Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

How to succesfully Invest and Basics

This was written for a different group /stocks it got deleted so hopefully this time it works !
Disclaimer
I dont want to sell you or recommend anything ! Just my expierence and little help so enjoy. If you want to ask me anything feel free, I try so answer everything.

This article is meant to be a small guide that helps you to find your way. Its based on my experience and knowledge, I gained throughout the years. Iam by far no professional. Iam just a guy who loves to invest. If you are new and have few grands to invest this article might help you.
My motivation to write this article was because when I turned 20 I got a small loan of 1 milli.... just few grands from my parents plus the savings I made from working. For me it was clear that I want to invest them. I always liked the idea making money and not really working for it! (Spoiler its kinda true and kinda not)
So I sum up few steps which will helped me to orientate and maybe help you to make your first investement
Step one 1. Where I can Invest?! You can basicly invest in everything. They are infinite options but I just cover up few topics.
They are 5 investments I would like to adress.
  1. Stocks.
    1. Real estate
    2. Options
    3. Start-ups
    4. Krypto n+1. art, old cars, drugs?! (Don’t do or sell drugs pls!)
Stocks (my fav.) I love stocks. I love understanding what the company’s plans are and where they are heading.
They are 3 different types of investment strategies.
  1. Short term (daily) That’s usually daily trading. That means you invest and sell on a daily basis. If your not a expert it can frustrating and the chances that you will lose is high. Many people forget that you have to pay taxes and fees so even if you for example invest 1.000 and sell for 1.050 within 20 min. You will have to pay some fees and taxes and with luck, you are where you started. It only makes sense when you invest a lot, otherwise it makes no sense and to be honest I don’t know any person which makes profit with it.
Difficulty: Hard
Stress Lvl: High
Risk: Medium/High
Profit: Usualy bad
Investement: Medium
  1. Mid term (6month – 1 year+) You buy some stocks for a longer period of time and hope it will go up soon.
This investment is much easier and less risky than short term. You see a stock going up and up so you invest 5k and hope you can ride a little on this upwards trend. Its fairly easy but you have to keep an eye on the market. A good example is VW it dropped because it has some Image problems. Thats a chance to invest! It will most likely to recover because its the biggest automarker in the world and it did. It happend 1000 times and normaly big companies dont fail they are exception but without risk you dont get anywhere
Difficulty: Medium
Stress: Medium
Risk: Medium
Profit: Good
Investment: Low
  1. Long term ( 1-2years – 10 years+) Means you want to invest for a long time you are not only interested in making a quick buck but making a slow and steady progress. You are not interested if the stock goes up or down but you are more interested how much divendend they pay. Usualy they go up very slowly but steady. A good example for this type of stock is Royal Dutch (shell) it has ist up and downs but compared to other stocks ist stable. The dividend is 6% which is insanly good no other big company will pay you that every year. You invest 10.000€ and get every year 600€ which means a holiday for free. Also the work is very little, you only have to check the stocks every few weeks/month You wont get rich but its better than having it in the bank.
Difficulty: Easy
Stress: Low
Risk: Low
Profit: Low
Investment: Low-Medium
Before you invest check the company read the news and get a good overview. I have to admit Iam a fanboy at heart. When a stock of one of my fav. company’s has potential and it does make sense to invest it feels like buying tickets for my favorite Rockband. You support and cheer them on and if they grow you grow with them. BUUUUUUT don’t get my wrong never buy stocks just because you like the company or they have a cool name.
All in all Stocks are a great Investment!
Real Estate
If you want to invest in houses it’s a very save and profitable investment but it depends on your area and country you are coming from. In Germany most objects are overpriced right now so it wouldnt make any sense to buy some. In generell the more money you have the better. They will will be much more people who can afford an cheap flat/condo than the other way around. So expensive objects are better! The optimum is always a shitty apartment in a very good area. Also buying objects in bad areas cause lots of trouble with tenant. Crazy families who refuse to pay, messy people etc. this can end in a stressful situation so beware of that.
If you are already rich af than buy propreties
Example
I went once to an auction and most apartments are sold for double the estimated value. It would take ages (20+ years) to get your investment back. So beware of your market situation.
Difficulty: Easy
Stress: Usualy low/medium
Risk: Low
Profit: Medium
Investment: High
Options
Options are basicly betting that a stock with go up or down. You can bet on nearly everything. You can make lot of money very quick and lose everything even quicker. For me option trading is gambling with few extra steps. The difference is you can lose more than you invest. They are cases where people invest 1000€ and lose -120.000€ because suddelny the market changed.
If you have gambling problems and tendency to gamble this is absolutly not for you. You can see here (in the forum) lots of bad examples where people going full YOLO on something and lose a ton of money. They save up a little, invest in something even more risky and lose again.
I know a friend who makes good money from it but he has a clear head and read many books about this topic he uses software to analyse the situation and everything and he admits that sometimes he doesnt understand what happend. Of course options are not the devils tool but I like to be the voice against it. The truth is in the middle.
Iam a person who likes to understand what am I doing. After reading and learning about it, for more than a year I was more confused than before. It is probably because Iam to stupid for it, so I gave it up and moved on. Options are not for me
Difficulty: very hard (at least for me)
Stress: high
Risk: low - very risky
Profit: It can be everything
Investment: low
  1. Start-ups
Start-ups are also a great business opportunity. I was lucky enough to invest once a little bit into a upcoming company from my firend. He showed me his company and the plans for the future. I already helped him with few shows and stuff so I knew how everything worked.
The biggest bullshit I ever saw are the analyse prediction of the future sales. During the last few years I saw few of them and they all predicted that the company will make an absurd amount of money. It looked like high cool project all shiny and with big numbers. To be honest I dont even know who pay these people to make such bullshit predictions, seriously.
(as you can see I love talking from my life so forgive me my dear)
Long story short I still invested because I understood their model. They existed and already made great progress. I made 50% profit in 3 years. I am still very happy and greatful to had such good chance to invest and would do it again.
They biggest question is how do I find such chances ?
Tell people you are intersted to invest maybe a friend of you will start an company and you can invest or help you to find such a opprtunity. I went to many start up meetings and talk about a lot with my friends. They dont want to hear it but I tell them anyway and if there is a chance they will call me.
Few Tipps:
- Look for already existing companys
- Most companys give you a very good inside look before you invest! If not watch out they hide something.
- Try to understand what they are doing and where they are heading
- Look what the will offer you for your money!
Difficulty: Medium/hard
Stress: Medium/low
Risk: Medium/High
Profit: Good/Very good
Investment: From Low to high
  1. Krypto
Boy oh boy where to start. I heard to many experts saying yeah krypto thats future boyyyyyy I invested everything BOYYYYYYY and in few month I will be rich BOIIIIII. I heard this story so often that Iam allgeric to it now. This irregulated mess based purly on speculations wasnt anything form me. I didnt invest a cent into it and had lots of chances when bitcoin was 300-500 €. It didnt simply fit into my portfolio. It had no function for me. You could pay for your drugs in the deep web and some hipster pizzerias accepted it but in generell it had no function. So investing into kryptos is just speclutions it has no real fundation what I like.
My friends who invested early made a ton of money but all the people on the Hypetrain crashed.
Difficulty: I dont know
Stress: Depends how much storys you make about it on Instagra´m
Risk: Over 9000
Profit: It can be everything from super high to low in just few days
Investment: What ever you want, if this is still to expensive for you, make your own coin and hope some Idiot buys it!
Now you know my knowledge ehh more like my opionen on few things now its time for……. Step. 2. Get a rough overview
Back than I didn’t know where to start so I asked everybody for advice like parents, friends , my parents friends, banks, forums, news etc. and got very different results.
Friends and family can be a good source of information how they did it. Of course often investments are impossible to repeat because they are 20 years ago but they can give some good advice. Its nice to hear few cool stories.
Example
Royal Dutch shell hast wo different stocks. One based in england (B) one Dutch version (A) (explained very simple, not 100% accurate). If you purchase Royal Dutch (A) you have to pay a 15% withholding tax that you wouldnt when you buy Royal Dutch (B).
Banks
Banks are terrible to ask. I always had shitty experience. The lured me into meetings, only to sell some shitty investment models from which they make some good money of me or some stupid insurence. They are not interested in your loses or profits they are interested to sell you the next stupid investement from which the make money. They never keep their promises and if you loose they will cheer you up and show their new hot investement and so on and so on until you loose and they drop you.
My mom works kind of in the finance sector and you wont believe home money older people lost ton of money because of this. I also found few very shady investements opportunities who would be illegal but I wont get into detail cause I dont have 100% proof for it and I also dont want to get in any trouble. As you can see Iam not big fan oft them and do not recommend!
News/charts/indexes/Forums
For me charts & news works the best. It’s easily so see what’s going on and gives you a great overview. The chart showed that a stock dropped 5%?! Good! Read the news/forums and find out what is going on! It’s that easy you don’t need 15 monitors and crazy software to understand what is happening. Dont make it to complicated! Have an easy overview about the market which you would like to invest.
Example
My parents invested around a year ago alot in Tesla. It was before Model 3 was released. Tesla had no expierence in mass production and it was clear (at least to me) that they wont have an easy start. They still made no profit and it was the first step to play with the big boys. Back than the Tesla stock was way over 300€ and it was based a lot on speculation and hype. It couldnt live up to they hype and dropped ≈ 30% - 35%.
  1. Few points & strategies
No Emotions
Never ever let your emotions guide you. Stocks are not based on a stomach feeling or any other emotion. Dont invest just because you like Elon Musk or Apple or anything. If I have a the chance to invest into one because the timing is right. Always make sure you know what you are doing. When it can wait a day, sleep a night about it and be sober! You can get sucked up into this world you will start giving a shit if you lose one grand and start digging deeper and deeper and lose sense the value of it. Stay sober and now when you have to stop.
Making losses
It will happend and dont freak out !
They are two options how to handle it and it depends on few things.
  1. Sell them, you see the ship is sinking and their no possibility you can save it than sell it, It hurts but better early than it is to late. Or you find a better possibility to invest for example a start up than its also fine.
  2. Keep it! Turning a Short/Mid-term investement into a long-term investement. Check first if the company will recover from it. For example the VW stocks dropped a lot due it scandal few years ago but it was clear that they will not go bankrupt so after a while they recover from it. Technically the market will grow infinite so after every crash they reach new heights, if you can wait that long the chances are high that you will make some profit and do not lose any money. Maybe the profit will be small but better than losing everything.
Diversity
Dont put all your eggs in one basket but also dont but every egg in a different basket. Have a good mix that you can still have an overview about your investment. Dont depend on one investment something bad can always happend. Having a good mix is important some investments will go up and few will go down. Its rearly that everything will crash (expect crises). So you can sell the good one and keep the bad ones until they go up.
Scams
Online
Stick to the basics! They are a ton of scammers online who want to show you a way to make fast money. Its mostly some MLM (multi level markting) aka Pryamide sheme, some buying and reselling some stuff from China or some weird option trading platform where pay in and your money is gone in 5 min without any trace o fit (no chance getting it back)! The Instagram advertisment is so ridiculous and I feel stupid mentioning it but hey if it wouldnt work they wouldnt exist. So please dont be this guy….
Offline
I really wanted to invest and have an own start-up. I met many people and visited countless seminars. Few of them offered me to invest but it was a mostly a mess. Onced I got fooled. A friend and I meet a person who had a start up for social media. We had some meetings restaurant he paid everything for us and looked very legit. I worked 3-4 month in this start up 3-4 hours a day, even on weekends for free. Only later to find out I was the only one working in it. (My friend pulled out very early cause he wanted to focus on his PhD) They rest oft he Team did absolute nothing! All the money the company generated was based on my work. They didnt make a lot of money but around 600-800€ a month. The founder spend all the money on vacation and stuff. I never got anything. They wanted to sell me 10% of the company for 15.000€. I always said I need more inside infos, which of course I never got. So I pulled out and they went mad and threaten me to sue me. I feel to this day ashamed that I trusted them and didnt saw it.
If you want get into something like this make a contract dont rely on handshakes people will tell you everything and wont keep it. I learned it the hard way
Be open minded
I met enough people who dont want to share with me their portfolio because they are scared that I will steal something from them. Its stupid! Talk to as many people als possible about your investment. Some amazing things can happend. I meet to many great people because of that and with some I share a 5+ years long friendship maybe we dont share the same ideas but I leanred a lot of it and sometimes I made some profit because of it! Be open !
Prediction & graphic lines
When I did my first Investment (it was gold) I read every morning every article about it I could for at least a solid year. Every monring 20 min Thats rouhly 120 hours. Thats time I will never get back. It was wasted time. The news/articels predicted everything. It was a rollercoaster. I believed it in the beginning because it was new to me. It really messed me up and I spend way to much time overthinking. Its fine to see a prediction but the more extreme it is the more it will never happend.
Also the trendlines are mostly worthless. I read so many people talking about the 50 day trendline or the 200 day trendline. It only idicates if a stock goes up or down but people interepte everything into it. “Oh yeah you can see the restience at 12.50 if it will drop below everbody will sell“. The next day it dropped and nothing happend. Dont believe everything in the internet. (lol)
Keep it simple
Dont make it to complicated you can have the best infos and charts and everything in the world and still lose everything. So dont make it to hard for yourself.
THE MOST IMPORTANT ADVICE
No depts
Dont take a credit just because you know a great investment. No matter how much you could earn DO NOT TAKE A CREDIT. This can not only ruin you financily but also your family and your whole life. This is no joke! Make no depts.
DO NOT MAKE FUCKING DEBTS!
My Strategy
It is a mixture of long term and mid-term stock investments. Its very easy I invested in:
Before I buy some
- Royal Dutch because of the high dividend
- Deutsche Bank when the hit nearly a all time low hoping to recover (still hoping ☹ )
- Lufthansa because they bought few airlines and hopefully will grow but its not (thanks Greta !)
- Tesla because they are low and made some good deals for the future. (update, sold it and made 30-35% in 6 weeks)
Am I rich or making a lot of money?! Hell no! But Iam making enough to pay for my holidays and few extras. I am patient enough to sit out bad times. I never sold anything with loose and I want to keep it that way. I like having a clean record.
Thanks for reading and feel free to ask my everything.

The Great Bitcoin Bull Market Of 2017 by Trace Mayer

By: Trace Mayer, host of The Bitcoin Knowledge Podcast.
Originally posted here with images and Youtube videos.
I just got back from a two week vacation without Internet as I was scouring some archeological ruins. I hardly thought about Bitcoin at all because there were so many other interesting things and it would be there when I got back.
Jimmy Song suggested I do an article on the current state of Bitcoin. A great suggestion but he is really smart (he worked on Armory after all!) so I better be thorough and accurate!
Therefore, this article will be pretty lengthy and meticulous.
BACKGROUND
As I completely expected, the 2X movement from the New York Agreement that was supposed to happen during the middle of my vacation flopped on its face because Jeff Garzik was driving the clown car with passengers willfully inside like Coinbase, Blockchain.info, Bitgo and Xapo and there were here massive bugS and in the code and miners like Bitmain did not want to allocate $150-350m to get it over the difficulty adjustments.
I am very disappointed in their lack of integrity with putting their money where their mouths are; myself and many others wanted to sell a lot of B2X for BTC!
On 7 December 2015, with Bitcoin trading at US$388.40, I wrote The Rise of the Fourth Great Bitcoin Bubble. On 4 December 2016, with Bitcoin trading at US$762.97, I did this interview:

As of 26 November 2017, Bitcoin is trading around US$9,250.00. That is an increase of about 2,400% since I wrote the article prognosticating this fourth great Bitcoin bull market. I sure like being right, like usual (19 Dec 2011, 1 Jul 2013), especially when there are financial and economic consequences.
With such massive gains in such a short period of time the speculative question becomes: Buy, Hold or Sell?
FUNDAMENTALS
Bitcoin is the decentralized censorship-resistant Internet Protocol for transferring value over a communications channel.
The Bitcoin network can use traditional Internet infrastructure. However, it is even more resilient because it has custom infrastructure including, thanks to Bitcoin Core developer Matt Corrallo, the FIBRE network and, thanks to Blockstream, satellites which reduce the cost of running a full-node anywhere in the world to essentially nothing in terms of money or privacy. Transactions can be cheaply broadcast via SMS messages.
SECURITY
The Bitcoin network has a difficulty of 1,347,001,430,559 which suggests about 9,642,211 TH/s of custom ASIC hardware deployed.
At a retail price of approximately US$105/THs that implies about $650m of custom ASIC hardware deployed (35% discount applied).
This custom hardware consumes approximately 30 TWh per year. That could power about 2.8m US households or the entire country of Morocco which has a population of 33.85m.
This Bitcoin mining generates approximately 12.5 bitcoins every 10 minutes or approximately 1,800 per day worth approximately US$16,650,000.
Bitcoin currently has a market capitalization greater than $150B which puts it solidly in the top-30 of M1 money stock countries and a 200 day moving average of about $65B which is increasing about $500m per day.
Average daily volumes for Bitcoin is around US$5B. That means multi-million dollar positions can be moved into and out of very easily with minimal slippage.
When my friend Andreas Antonopolous was unable to give his talk at a CRYPSA event I was invited to fill in and delivered this presentation, impromptu, on the Seven Network Effects of Bitcoin.
These seven network effects of Bitcoin are (1) Speculation, (2) Merchants, (3) Consumers, (4) Security [miners], (5) Developers, (6) Financialization and (7) Settlement Currency are all taking root at the same time and in an incredibly intertwined way.
With only the first network effect starting to take significant root; Bitcoin is no longer a little experiment of magic Internet money anymore. Bitcoin is monster growing at a tremendous rate!!

SPECULATION
For the Bitcoin price to remain at $9,250 it requires approximately US$16,650,000 per day of capital inflow from new hodlers.
Bitcoin is both a Giffen good and a Veblen good.
A Giffen good is a product that people consume more of as the price rises and vice versa — seemingly in violation of basic laws of demand in microeconomics such as with substitute goods and the income effect.
Veblen goods are types of luxury goods for which the quantity demanded increases as the price increases in an apparent contradiction of the law of demand.
There are approximately 16.5m bitcoins of which ~4m are lost, ~4-6m are in deep cold storage, ~4m are in cold storage and ~2-4m are salable.
(http://www.runtogold.com/images/lost-bitcoins-1.jpg)
(http://www.runtogold.com/images/lost-bitcoins-2.jpg)
And forks like BCash (BCH) should not be scary but instead be looked upon as an opportunity to take more territory on the Bitcoin blockchain by trading the forks for real bitcoins which dries up more salable supply by moving it, likely, into deep cold storage.
According to Wikipedia, there are approximately 15.4m millionaires in the United States and about 12m HNWIs ($30m+ net worth) in the world. In other words, if every HNWI in the world wanted to own an entire bitcoin as a 'risk-free asset' that cannot be confiscated, seized or have the balance other wise altered then they could not.
For wise portfolio management, these HNWIs should have at least about 2-5% in gold and 0.5-1% in bitcoin.
Why? Perhaps some of the 60+ Saudis with 1,700 frozen bank accounts and about $800B of assets being targetted might be able to explain it to you.
In other words, everyone loves to chase the rabbit and once they catch it then know that it will not get away.
RETAIL
There are approximately 150+ significant Bitcoin exchanges worldwide. Kraken, according to the CEO, was adding about 6,000 new funded accounts per day in July 2017.
Supposedly, Coinbase is currently adding about 75,000 new accounts per day. Based on some trade secret analytics I have access to; I would estimate Coinbase is adding approximately 17,500 new accounts per day that purchase at least US$100 of Bitcoin.
If we assume Coinbase accounts for 8% of new global Bitcoin users who purchase at least $100 of bitcoins (just pulled out of thin error and likely very conservative as the actual number is perhaps around 2%) then that is approximately $21,875,000 of new capital coming into Bitcoin every single day just from retail demand from 218,750 total new accounts.
What I have found is that most new users start off buying US$100-500 and then after 3-4 months months they ramp up their capital allocation to $5,000+ if they have the funds available.
After all, it takes some time and practical experience to learn how to safely secure one's private keys.
To do so, I highly recommend Bitcoin Core (network consensus and full validation of the blockchain), Armory (private key management), Glacier Protocol (operational procedures) and a Puri.sm laptop (secure non-specialized hardware).
WALL STREET
There has been no solution for large financial fiduciaries to invest in Bitcoin. This changed November 2017.
LedgerX, whose CEO I interviewed 23 March 2013, began trading as a CFTC regulated Swap Execution Facility and Derivatives Clearing Organization.
The CME Group announced they will begin trading in Q4 2017 Bitcoin futures.
The CBOE announced they will begin trading Bitcoin futures soon.
By analogy, these institutional products are like connecting a major metropolis's water system (US$90.4T and US$2 quadrillion) via a nanoscopic shunt to a tiny blueberry ($150B) that is infinitely expandable.
This price discovery could be the most wild thing anyone has ever experienced in financial markets.
THE GREAT CREDIT CONTRACTION
The same week Bitcoin was released I published my book The Great Credit Contraction and asserted it had now begun and capital would burrow down the liquidity pyramid into safer and more liquid assets.
(http://www.runtogold.com/images/Great-Credit-Contraction-Liquidity-Pyramid.jpg)
Thus, the critical question becomes: Is Bitcoin a possible solution to the Great Credit Contraction by becoming the safest and most liquid asset?
BITCOIN'S RISK PROFILE
At all times and in all circumstances gold remains money but, of course, there is always exchange rate risk due to price ratios constantly fluctuating. If the metal is held with a third-party in allocated-allocated storage (safest possible) then there is performance risk (Morgan Stanley gold storage lawsuit).
But, if properly held then, there should be no counter-party risk which requires the financial ability of a third-party to perform like with a bank account deposit. And, since gold exists at a single point in space and time therefore it is subject to confiscation or seizure risk.
Bitcoin is a completely new asset type. As such, the storage container is nearly empty with only $150B.
And every Bitcoin transaction effectively melts down every BTC and recasts it; thus ensuring with 100% accuracy the quantity and quality of the bitcoins. If the transaction is not on the blockchain then it did not happen. This is the strictest regulation possible; by math and cryptography!
This new immutable asset, if properly secured, is subject only to exchange rate risk. There does exist the possibility that a software bug may exist that could shut down the network, like what has happened with Ethereum, but the probability is almost nil and getting lower everyday it does not happen.
Thus, Bitcoin arguably has a lower risk profile than even gold and is the only blockchain to achieve security, scalability and liquidity.
To remain decentralized, censorship-resistant and immutable requires scalability so as many users as possible can run full-nodes.
(http://www.runtogold.com/images/ethereum-bitcoin-scability-nov-2017.png)
TRANSACTIONS
Some people, probably mostly those shilling alt-coins, think Bitcoin has a scalability problem that is so serious it requires a crude hard fork to solve.
On the other side of the debate, the Internet protocol and blockchain geniuses assert the scalability issues can, like other Internet Protocols have done, be solved in different layers which are now possible because of Segregated Witness which was activated in August 2017.
Whose code do you want to run: the JV benchwarmers or the championship Chicago Bulls?
As transaction fees rise, certain use cases of the Bitcoin blockchain are priced out of the market. And as the fees fall then they are economical again.
Additionally, as transaction fees rise, certain UTXOs are no longer economically usable thus destroying part of the money supply until fees decline and UTXOs become economical to move.
There are approximately 275,000-350,000 transactions per day with transaction fees currently about $2m/day and the 200 DMA is around $1.08m/day.
(http://www.runtogold.com/images/bitcoin-transaction-fees-nov-2017.png)
What I like about transaction fees is that they somewhat reveal the financial health of the network.
The security of the Bitcoin network results from the miners creating solutions to proof of work problems in the Bitcoin protocol and being rewarded from the (1) coinbase reward which is a form of inflation and (2) transaction fees which is a form of usage fee.
The higher the transaction fees then the greater implied value the Bitcoin network provides because users are willing to pay more for it.
I am highly skeptical of blockchains which have very low transaction fees. By Internet bubble analogy, Pets.com may have millions of page views but I am more interested in EBITDA.
DEVELOPERS
Bitcoin and blockchain programming is not an easy skill to acquire and master. Most developers who have the skill are also financially independent now and can work on whatever they want.
The best of the best work through the Bitcoin Core process. After all, if you are a world class mountain climber then you do not hang out in the MacDonalds play pen but instead climb Mount Everest because that is where the challenge is.
However, there are many talented developers who work in other areas besides the protocol. Wallet maintainers, exchange operators, payment processors, etc. all need competent developers to help build their businesses.
Consequently, there is a huge shortage of competent developers. This is probably the largest single scalability constraint for the ecosystem.
Nevertheless, the Bitcoin ecosystem is healthier than ever before.
(http://www.runtogold.com/images/bitcoin-ecosystem.jpg)(/images/bitcoin-ecosystem-small.jpg)
SETTLEMENT CURRENCY
There are no significant global reserve settlement currency use cases for Bitcoin yet.
Perhaps the closest is Blockstream's Strong Federations via Liquid.
PRICE
There is a tremendous amount of disagreement in the marketplace about the value proposition of Bitcoin. Price discovery for this asset will be intense and likely take many cycles of which this is the fourth.
Since the supply is known the exchange rate of Bitcoins is composed of (1) transactional demand and (2) speculative demand.
Interestingly, the price elasticity of demand for the transactional demand component is irrelevant to the price. This makes for very interesting dynamics!
(http://www.runtogold.com/images/bitcoin-speculation.jpg)
On 4 May 2017, Lightspeed Venture Partners partner Jeremy Liew who was among the early Facebook investors and the first Snapchat investor laid out their case for bitcoin exploding to $500,000 by 2030.
On 2 November 2017, Goldman Sachs CEO Lloyd Blankfein (https://www.bloomberg.com/news/articles/2017-11-02/blankfein-says-don-t-dismiss-bitcoin-while-still-pondering-value)said, "Now we have paper that is just backed by fiat...Maybe in the new world, something gets backed by consensus."
On 12 Sep 2017, JP Morgan CEO called Bitcoin a 'fraud' but conceded that "(http://fortune.com/2017/09/12/jamie-dimon-bitcoin-cryptocurrency-fraud-buy/)Bitcoin could reach $100,000".
Thus, it is no surprise that the Bitcoin chart looks like a ferret on meth when there are such widely varying opinions on its value proposition.
I have been around this space for a long time. In my opinion, those who scoffed at the thought of $1 BTC, $10 BTC (Professor Bitcorn!), $100 BTC, $1,000 BTC are scoffing at $10,000 BTC and will scoff at $100,000 BTC, $1,000,000 BTC and even $10,000,000 BTC.
Interestingly, the people who understand it the best seem to think its financial dominance is destiny.
Meanwhile, those who understand it the least make emotionally charged, intellectually incoherent bearish arguments. A tremendous example of worldwide cognitive dissonance with regards to sound money, technology and the role or power of the State.
Consequently, I like looking at the 200 day moving average to filter out the daily noise and see the long-term trend.
(http://www.runtogold.com/images/bitcoin-price-200dma-nov-2017.png)
Well, that chart of the long-term trend is pretty obvious and hard to dispute. Bitcoin is in a massive secular bull market.
The 200 day moving average is around $4,001 and rising about $30 per day.
So, what do some proforma situations look like where Bitcoin may be undervalued, average valued and overvalued? No, these are not prognostications.
(http://www.runtogold.com/images/bitcoin-price-pro-forma.png)
Maybe Jamie Dimon is not so off his rocker after all with a $100,000 price prediction.
We are in a very unique period of human history where the collective globe is rethinking what money is and Bitcoin is in the ring battling for complete domination. Is or will it be fit for purpose?
As I have said many times before, if Bitcoin is fit for this purpose then this is the largest wealth transfer in the history of the world.
CONCLUSION
Well, this has been a brief analysis of where I think Bitcoin is at the end of November 2017.
The seven network effects are taking root extremely fast and exponentially reinforcing each other. The technological dominance of Bitcoin is unrivaled.
The world is rethinking what money is. Even CEOs of the largest banks and partners of the largest VC funds are honing in on Bitcoin's beacon.
While no one has a crystal ball; when I look in mine I see Bitcoin's future being very bright.
Currently, almost everyone who has bought Bitcoin and hodled is sitting on unrealized gains as measured in fiat currency. That is, after all, what uncharted territory with daily all-time highs do!
But perhaps there is a larger lesson to be learned here.
Riches are getting increasingly slippery because no one has a reliable defined tool to measure them with. Times like these require incredible amounts of humility and intelligence guided by macro instincts.
Perhaps everyone should start keeping books in three numéraires: USD, gold and Bitcoin.
Both gold and Bitcoin have never been worth nothing. But USD is a fiat currency and there are thousands of those in the fiat currency graveyard. How low can the world reserve currency go?
After all, what is the risk-free asset? And, whatever it is, in The Great Credit Contraction you want it!
What do you think? Disagree with some of my arguments or assertions? Please, eviscerate them on Twitter or in the comments!

Bitcoin Mining & The Beauty Of Capitalism

Authored by Valentin Schmid via The Epoch Times,
While the price of bitcoin drops, miners get more creative... and some flourish.
The bitcoin price is crashing; naysayers and doomsayers are having a field day. The demise of the dominant cryptocurrency is finally happening — or is it?
Bitcoin has been buried hundreds of times, most notably during the brutal 90 percent decline from 2013 to 2015. And yet it has always made a comeback.
Where the skeptics are correct: The second bitcoin bubble burst in December of last year and the price is down roughly 80 percent from its high of $20,000. Nobody knows whether and when it will see these lofty heights again.
As a result, millions of speculators have been burned, and big institutions haven’t showed up to bridge the gap.
This also happened on a smaller scale in 2013 after a similar 100x run-up, and it was necessary.

Time to Catch Up

What most speculators and even some serious proponents of the independent and decentralized monetary system don’t understand: Bitcoin needs these pauses to make improvements in its infrastructure.
Exchanges, which could not handle the trading volumes at the height of the frenzy and did not return customer service inquiries, can take a breather and upgrade their systems and hire capable people.
The technology itself needs to make progress and this needs time. Projects like the lightning network, a system which delivers instant bitcoin payments at very little cost and at virtually unlimited scale is now only available to expert programmers.
A higher valuation is only justified if these improvements reach the mass market.
And since we live in a world where everything financial is tightly regulated, for better or worse, this area also needs to catch up, since regulators are chronically behind the curve of technological progress.
And of course, there is bitcoin mining. The vital infrastructure behind securing the bitcoin network and processing its transactions has been concentrated in too few hands and in too few places, most notably China, which still hosts about 70 percent of the mining capacity.

The Case For Mining

Critics have always complained that bitcoin mining consumes “too much” electricity, right now about as much as the Czech Republic. In energy terms this is around 65 terawatt hours or 230,000,000 gigajoules, costing $3.3 billion dollars according to estimates by Digiconomist.
For the non-physicists among us, this is around as much as consumed by six million energy-guzzling U.S. households per year.
All those estimates are imprecise because the aggregate cannot know how much energy each of the different bitcoin miners consumes and how much that electricity costs. But they are a reasonable rough estimate.
So it’s worth exploring why mining is necessary to begin with and whether the electricity consumption is justified.
Anything and everything humans do consumes resources. The question then is always: Is it worth it? And: Who decides?
This question then leads to the next question: Is it worth having and using money? Most people would argue yes, because using money instead of barter in fact makes economic transactions faster and cheaper and thus saves resources, natural and human.

_Merchants exchange goods with the inhabitants of Tidore, Indonesia, circa 1550. Barter was supplanted by using money because it is more efficient. (Archive/Getty Images)_If we are generously inclined, we will grant bitcoin the status of a type of money or at least currency as it meets the general requirements of being recognizable, divisible, portable, durable, is accepted in exchange for other goods and services, and in this case it is even limited in supply.
So having any type of money has a price, whether it’s gold, dollar bills, or numbers on the screen of your online banking system. In the case of bitcoin, it’s the electricity and the capital for the computing equipment, as well as the human resources to run these operations.
If we think having money in general is a good idea and some people value the decentralized and independent nature of bitcoin then it would be worth paying for verifying transactions on the bitcoin network as well as keeping the network secure and sound: Up until the point where the resources consumed would outweigh the efficiency benefits. Just like most people don’t think it’s a bad idea to use credit cards and banks, which consume electricity too.
However, bitcoin is a newcomer and this is why it’s being scrutinized even more so than the old established players.

Different Money, Different Costs

How many people know how much electricity, human lives, and other resources gold mining consumes or has consumed in the course of history? What about the banking system? Branches, servers, air-conditioning, staff? What about printing dollar notes and driving them around in armored trucks?
What about the social effects of monetary mismanagement of bank and government money like inflation as well as credit deflations? Gold gets a pass here.
Most people haven’t asked that question, which is why it’s worth pointing out the only comprehensive study done on the topic in 2014. In “An Order of Magnitude” the engineer Hass McCook analyzes the different money systems and reaches mind-boggling conclusions.
The study is a bit dated and of course the aggregations are also very rough estimates, but the ball park numbers are reasonable and the methodology sound.
In fact, according to the study, bitcoin is the most economic of all the different forms of money.
Gold mining in 2014 used 475 million GJ, compared to bitcoin’s 230 million in 2018. The banking system in 2014 used 2.3 billion gigajoules.
Over 100 people per year die trying to mine gold. But mining costs more than electricity. It consumes around 300,000 liters of water per kilogram of gold mined as well as 150 kilogram (330 pounds) of cyanide and 1500 tons of waste and rubble.
The international banking system has been used in all kinds of fraudulent activity throughout history: terrorist financing, money laundering, and every other criminal activity under the sun at a cost of trillions of dollars and at an order of magnitude higher than the same transactions done with cryptocurrency and bitcoin.
And of course, while gold has a relatively stable value over time, our bank and government issued money lost about 90 percent of its purchasing power over the last century, because it can be created out of thin air. This leads to inflation and a waste of physical and human resources because it distorts the process of capital allocation.

_The dollar has lost more than 90 percent of its value since the creation of the Federal Reserve in 1913. (Source: St. Louis Fed)_This is on top of the hundreds of thousands of bank branches, millions of ATMs and employees which all consume electricity and other resources, 10 times as much electricity alone as the bitcoin network.
According to monetary philosopher Saifedean Ammous, author of “The Bitcoin Standard,” the social benefit of hard money, i.e. money that can’t be printed by government decree, cannot even be fathomed; conversely, the true costs of easy money—created by government fiat and bank credit—are difficult to calculate.
According to Ammous, bitcoin is the hardest money around, even harder than gold because its total supply is capped, whereas the gold supply keeps increasing at about 1-2 percent every year.
“Look at the era of the classical gold standard, from 1871, the end of the Franco–Prussian War, until the beginning of World War I. There’s a reason why this is known as the Golden Era, the Gilded Age, and La Belle Epoque. It was a time of unrivaled human flourishing all over the world. Economic growth was everywhere. Technology was being spread all over the world. Peace and prosperity were increasing everywhere around the world. Technological innovations were advancing.
“I think this is no coincidence. What the gold standard allowed people to do is to have a store of value that would maintain its value in the future. And that gave people a low time preference, that gave people the incentive to think of the long term, and that made people want to invest in things that would pay off over the long term … bitcoin is far closer to gold. It is a digital equivalent of gold,” he said in an interview with The Epoch Times.
Of course, contrary to the gold standard that Ammous talks about, bitcoin doesn’t have a track record of being sound money in practice. In theory it meets all the criteria, but in the real world it hasn’t been adopted widely and has been so volatile as to be unusable as a reliable store of value or as the underlying currency of a productive lending market.
The proponents argue that over time, these problems will be solved the same way gold spread itself throughout the monetary sphere replacing copper and seashells, but even Ammous concedes the process may take decades and the outcome is far from certain. Gold is the safe bet for sound money, bitcoin has potential.
There is another measure where bitcoin loses out, according to a recent study by researchers from the Oak Ridge Institute in Cincinnati, Ohio.
It is the amount of energy expended per dollar for different monetary instruments. One dollar worth of bitcoin costs 17 megajoules to mine versus five for gold and seven for platinum. But the study omits the use of cyanide, water, and other physical resources in mining physical metals.
In general, the comparisons in dollar terms go against bitcoin because it is worth relatively less, only $73 billion in total at the time of writing. An issue that could be easily fixed at a higher price, but a higher price is only justified if the infrastructure improves, adoption increases, volatility declines, and the network proves its resilience to attacks over time.
In the meantime, market participants still value the fact they can own a currency independent of the government, completely digital, easily fungible, and limited in supply, and relatively decentralized. And the market as a whole is willing to pay a premium for these factors reflected in the higher per dollar prices for mining bitcoin.

The Creativity of Bitcoin Mining

But where bitcoin mining lacks in scale, it makes up for it in creativity.
In theory—and in practice—bitcoin mining can be done anywhere where there is cheap electricity. So bitcoin mining operations can be conducted not where people are (banking) or where government is (fiat cash) or where gold is (gold mining)—it can be done everywhere where there is cheap electricity
Some miners are flocking to the heat of the Texan desert where gas is virtually available for free, thanks to another oil revolution.
Other miners go to places where there is cheap wind, water, or other renewable energy.
This is because they don’t have to build bank branches, printing presses, and government buildings, or need to put up excavators and conveyor belts to dig gold out of the ground.
All they need is internet access and a home for the computers that look like a shipping container, each one of which has around 200 specialized bitcoin mining computers in them.
“The good thing about bitcoin mining is that it doesn’t matter where on earth a transaction happens, we can verify it in our data center here. The miners are part of the decentralized philosophy of bitcoin, it’s completely independent of your location as well,” said Moritz Jäger, chief technology officer at bitcoin Mining company Northern Bitcoin AG.

Centralized Mining

But so far, this decentralization hasn’t worked out as well as it sounds in theory.
Because Chinese local governments had access to subsidized electricity, it was profitable for officials to cut deals with bitcoin mining companies and supply them with cheap electricity in exchange for jobs and cutbacks. Sometimes the prices were as low as 2 dollar cents to 4 dollar cents per kilowatt hour.
This is why the majority of bitcoin mining is still concentrated in China (around 70 percent) where it was the most profitable, but only because the Chinese central planners subsidized the price of electricity.
This set up led to the by and large unwanted result that the biggest miner of bitcoin, a company called Bitmain, is also the biggest manufacturer of specialized computing equipment for bitcoin mining. The company reported revenues of $2.8 billion for the first half of 2018.

Tourists walk on the dunes near a power plant in Xiangshawan Desert in Ordos of Inner Mongolia, in this file photo. bitcoin miners have enjoyed favorable electricity rates in places like Ordos for a long time. (Feng Li/Getty Images)Centralized mining is a problem because whenever there is one player or a conglomerate of players who control more than 50 percent of the network computing power, they could theoretically crash the network by spending the same bitcoin twice, the so called “double spending problem.“
They don’t have an incentive to do so because it would probably ruin the bitcoin price and their business, but it’s better not to have to rely on one group of people controlling an entire money system. After all, we have that exact same system with central banking and bitcoin was set up as a decentralized alternative.
So far, no player or conglomerate ever reached that 51 percent threshold, at least not since bitcoin’s very early days, but many market participants always thought Bitmain’s corner of the market is a bit too close for comfort.
This favorable environment for Chinese bitcoin mining has been changing with a crack down on local government electricity largess as well as a crackdown on cryptocurrency.
Bitcoin itself and mining bitcoin remain legal in China but cryptocurrency exchanges have been banned since late 2017.
But more needs to be done for bitcoin to become independent of the caprice of a centralized oppressive regime and local government bureaucrats.

Northern Bitcoin Case Study

Enter Northern Bitcoin AG. The company isn’t the only one which is exploring mining opportunities with renewable energies in locations other than China.
But it is special because of the extraordinary set up it has for its operations, the fact that it is listed on the stock exchange in Germany, and the opportunities for scaling it discovered.
The operations of Northern Bitcoin combine the beauties of bitcoin and capitalism in one.
Like Texas has a lot of oil and free gas and it makes sense to use the gas rather than burn it, Norway has a lot of water, especially water moving down the mountains due to rainfall and melting snow.
And it makes sense to use the power of the movement of the water, channel it through pipes into generators to create very cheap and almost unlimited electricity. Norway generates north of 95 percent of its total electricity from hydropower.

A waterfall next to a hydropowerplant near Sandane, Norway, Oct. 25, 2018. (Valentin Schmid/The Epoch Times)Capitalism does not distinguish between renewable and fossil. It uses what is the most expedient. In this case, it is clearly water in Norway, and gas in Texas.
As a side note on the beauties of real capital and the fact that capital and the environment need not be enemies, the water in one of the hydropowerplants close to the Northern Bitcoin facility is piped through a generator made in 1920 by J.M. Voith AG, a company from Heidenheim Germany.
The company was established in 1867 and is still around today. The generator was produced in 1920 and is still producing electricity today.

Excess Power

In the remote regions of Northern Norway, there aren’t that many people or industry who would use the electricity. And rather than transport it over hundreds of miles to the industrial centers of Europe, the industries of the future are moving to Norway to the source of the cheap electricity.
Of course, it is not just bitcoin mining, but other data and computing heavy operations like server farms for cloud computing that can be neatly packaged into one of those containers and shipped up north.
“The containers are beautiful. They are produced in the middle of Germany where the hardware is enabled and tested. Then we put it on a truck and send it up here. When the truck arrives on the outside we lift it on the container vehicle. Two hours after the container arrives, it’s in the container rack. And 40 hours later we enable the cooling, network, power, other systems, and it’s online,” said Mats Andersson, a spokesman for the Lefdal Mine data center in Måløy, Norway, where Northern Bitcoin has its operations. Plug and play.

(Northern Bitcoin)If the cheap electricity wasn’t enough—around 5 cents per kilowatt hour compared to 17 cents in Germany—Norway also provides the perfect storage for these data containers, which are normally racked up in open air parks above the ground.
Also here, the resource allocation is beautiful. Instead of occupying otherwise useful and beautiful parcels of land and nature, the Northern Bitcoin containers and others are stored in the old Lefdal olivine mine.
Olivine is a mineral used for steel production and looks green. Very fitting. Hence also the name of the data center: Lefdal Mine.
“We take the green mineral out and we take the green IT in,” said Andersson.

Efficiency, Efficiency

Using the old mine as storage for the data center makes the whole process even more resource efficient.
Why? So far, we’ve only been talking about bitcoin mining using a lot of energy. But what for? Before you have actually seen the process in action—and it is similar for other computing operations—you cannot imagine how bizarre it is.
Most of the electricity is used to prevent the computers from overheating. So it’s not even the processors themselves; it’s the fans which cool the computer that use the most juice.
This is where the mine helps, because it’s rather cool 160 meters (525 feet) below sea level; certainly cooler than in the Texas desert.
But it gets even better. On top of the air blow-cooling the computer, the Lefdal data center uses a fresh water system to pump through the containers in pipes.
The fans can then circulate air over the cool pipes which transfer the heat to the water. One can feel the difference when touching the different pipes.
The fresh water closed circle loop then completes the “green” or resource efficiency cycle by transferring its heat to ice cold water from the nearby Fjord.
The water is sucked in through a pipe from the Fjord, the heat gets transferred without the water being mixed, and the water flows back to the Fjord, without any impact on the environment.
To top it all off, the mine has natural physical security far better than open air data centers and is even protected from an electromagnetic pulse blast because it’s underground.

Given this superlative set up, Northern Bitcoin wants to ramp up production as fast as possible at the Lefdal mine and other similar places in Norway, which have more mountains where data centers can be housed.
At the moment, Northern Bitcoin has 15 containers with 210 mining machines each. The 15 containers produce around 5 bitcoin per day at a total cost of around $2,500 dollars at the end of November 2018 and after the difficulty of solving the math problems went down by ~17 percent.
Most of it is for electricity; the rest is for leasing the containers, renting the mine space, buying and writing off the mining computers, personnel, overhead, etc.
Even at the current relatively depressed prices of around $4000, that’s a profit of $1500 per bitcoin or $7,500 per day.
But the goal is to ramp it up to 280 containers until 2019, producing 100 bitcoin per day. Again, the company is in the sweet spot to do this.
As opposed to the beginning of the year when one could not procure a mining computer from Bitmain even if one’s life depended on it, the current bear market has made them cheap and relatively available both new and second had from miners who had to cease operations because they can’t produce at low bitcoin prices.

Northern Bitcoin containers inside the Lefdal Mine data center in Måløy, Norway. (Northern Bitcoin)What about the data shipping containers? They are manufactured by a company called Rittal who is the world market leader. So it helps that the owner of Rittal also owns 30 percent of the Lefdal mine, providing preferential access to the containers.
Northern Bitcoin said it has enough capital available for the intermediate goal of ramping up to 50 containers until the end of year but may tap the capital markets again for the next step.
The company can also take advantage of the lower German corporate tax rate because revenue is only recorded when the bitcoin are sold in Germany, not when they are mined in Norway.
Of course, every small-cap stock—especially bitcoin companies—have their peculiarities and very high risks. As an example, Northern Bitcoin’s financial statements, although public, aren’t audited.
The equipment in the Lefdal mine in Norway is real and the operations are controlled by the Lefdal personnel, but one has to rely on exclusive information from the company for financials and cost figures, so buyer beware.

Norway Powerhouse?

Northern Bitcoin wants to have 280 containers, representing around 5 percent of the network’s computing power.
But the Lefdal mine alone has a capacity to power and cool 1,500 containers in a 200 megawatt facility, once it is fully built out.
“Here you have all the space, power, and cooling that you need. … Here you can grow,” said Lefdal’s Andersson.

A mine shaft in the Lefdal Mine data center in Måløy, Norway. The whole mine will have a capacity for 1500 containers once fully built out. (Valentin Schmid/The Epoch Times)The Norwegian government was behind an initiative to bring computing power to Norway and make it one of the prime destinations for data centers at the beginning of this decade.
To that effect, the local governments own part of the utility companies which operate the power plants and own part of the Lefdal Mine and other locations. But even without notable subsidies (i.e. cash payments to companies), market players were able to figure it out, for everybody’s benefit.
The utilities win because they can sell their cheap electricity close to home. The computing companies like IBM and Northern Bitcoin win because they can get cheap electricity, storage, and security. Data center operators like Lefdal win because they can charge rent for otherwise unused and unneeded space.
However, in a recent about face, the central government in Oslo has decided to remove cryptocurrency miners from the list of companies which pay a preferential tax rate on electricity consumption.
Normally, energy intensive companies, including data centers, pay a preferential tax on electricity consumed of 0.48 øre ($0.00056 ). According to a report by Norwegian media Aftenposten, this tax will rise to 16.58 øre ($0.019) in 2019 for cryptocurrency miners exclusively.
The argument by left wing politician Lars Haltbrekken who sponsored the initiative: “Norway cannot continue to provide huge tax incentives for the most dirty form of cryptocurrency output […] [bitcoin] requires a lot of energy and generates large greenhouse gas emissions globally.”
Since Norway generates its electricity using hydro, precisely the opposite is true: No greenhouse gas emissions, or any emissions for that matter would be produced, if all cryptomining was done in Norway. As opposed to China, where mining is done with coal and with emissions.
But not only in Norway is the share of renewable and emission free energy high. According to research by Coinshares, Bitcoin’s consumes about 77.6 percent of its energy in the form of renewables globally.
However self-defeating the arguments against bitcoin mining in Norway, the political initiative is moving forward. What it means for Northern Bitcoin is not clear, as they house their containers in Lefdal’s mixed data center, which also has other clients, like IBM.
“It’s not really decided yet; there are still big efforts from IT sectors and parties who are trying to change it. If the decision is taken it might apply for pure crypto sites rather than mixed data centers, like ours,” said Lefdal’s Andersson.
Even in the worst-case scenario, it would mean an increase from ~5 cents to ~6.9 cents per kilowatt hour, or 30 percent more paid on the electricity by Northern Bitcoin, which at ~$3250 would still rank it among the most competitive producers in the world.
Coinshares estimates the average production price at $6,800 per Bitcoin at $0,05 per kilowatt hour of electricity and an 18-months depreciation schedule, but concedes that a profitable miner could “[depreciate] mining gear over 24-30 months, or [pay] less for mining gear than our estimates.”
Jäger says Northern Bitcoin depreciates the equipment over three years and has obtained very favorable prices from Bitmain, making its production much more competitive than the average despite the same cost of electricity. In addition, the natural cooling in the mine also reduces electricity costs overall.

Cheap Producer Advantage

At the moment, however, the tax could be the least of any miners worry, as the bitcoin price is in free-fall.
But what happens when the price crashes further? Suffice it to say that there was bitcoin mining when the dollar price was less than 1 cent and there will be bitcoin mining at lower prices thanks to the design of the network.
Mao Shixing, the founder of mining pool F2pool estimated 600,000 miners have shut down since the November crash in price, according to a report by Coindesk.
As it should be in a competitive system, the most energy intensive and obsolete machines are shut down first.
As with every other commodity, when the price drops, some miners will leave the market, leaving space for cheaper competitors to capture a bigger share. But with bitcoin this is a bit simpler than with copper or gold for example.
When a big copper player goes bankrupt, its competitors have to ramp up production and increase cost to increase their market share. With bitcoin, if 3,000 computers get taken off the total mining pool, they won’t be able to mine the approximately 5 bitcoin any longer.
However, because the difficulty of solving the computationally intensive cryptographic tasks of bitcoin decreases automatically when there are fewer computers engaged in the task, the other players just have to leave their machines running at the same rate for the same cost and they will split the 5 bitcoin among them.
“The moment the price goes down, our production price will go down as well,” said Jäger, a process that already happened from November to December when the difficulty decreased twice in November and the beginning of December.
This naturally favors players like Northern Bitcoin, which are producing at the lower end of the cost spectrum. They will be the ones who shut down last.
And this is a good thing. The more companies like Northern Bitcoin, and countries like Norway—even with the extra tax—the more decentralized the bitcoin system.
The more computers there are in different hands mining bitcoin, the more secure the system becomes, because it will be ever more difficult for one player to reach the 50 percent threshold to crash the system. It is this decentralized philosophy which has kept the bitcoin system running for 10 years. Whether at $1 or $20,000.

newbie lurker - some BTC impressions from the non-initiated

Disclaimer: Work in computer field, wanted to take a look at BTC as an investment, or mining it. It was a bit hard to get things going (considering I'm not a PC user newbie or something) and because I came in late, it was disappointing to realise mining without ASICs etc is essentially pointless, unless I mine an altcoin via CPU or GPU (mostly pointless), or perhaps take a chance on a less-adopted purchase like eth. I get it of course though, cheap power, early adoption, increasing difficulty, limited coins. I tried to read up anyway..
recently, I guess the drama with Craig Wright drew me in (I mean, it's quite the tale/effort) - to see what the latest state of things were. I was considering buying some BTC now its come down from the maximum height it was at. I've also been seriously considering buying a chunk of Litecoin, given it mirrors BTC value movements and has a higher quantity (though I worry about its adoption and always being seen as second-rate to BTC perhaps?)
All that said, I just wanted to share some first impressions, from someone coming from Fiat to BTC and trying to make it feel OK. Don't burn me and I know some are invalid...it's just me communicating an initial perception.
  1. The personalities and the basic infighting over the protocol(s). This has the potential to cause loss of value to the currency. This doesn't appear to be resolving. What am I to think? 2Mb blocks, soon?
  2. The delays and problems with the network transaction rate. I want to know I can send the BTC reliably, easily, between wallets or accounts etc. I don't know that right now. The horror stories of no confirmations, stuck transactions (incorrectly calculated fees), and various other extensive delays, are horrifying to someone like myself who doesn't have a fortune to invest (/lose/get stuck in limbo)
  3. Exchange credibility. again let me explain... If a bank exists in Australia it has to meet a lot of regulatory requirements, including guaranteeing customer deposits, holding insurance of various forms, not over-leveraging, etc. This means that the number of actual banks that fail (and result in all customers losing all funds) is miniscule. Mt Gox is hardly an isolated incident. In 2 weeks I've found literally - 20+ current issues happening, from people waiting extended periods of time to cash out from BTC to USD, or BTC to AUD, to $79 just going missing from an exchange account (explanation was bank charges when moving the converted fiat value around). Total loss of access to coins (stolen, shutdown, run). While this might statistically be 'rare' (compared to # of users), the severity when it happens is very high.
  4. As a value store. OK great, if I bought big anywhere before what 2010, I'm rolling in money now, and if I bought big at just the wrong time, I'm only down 70%. In theory that's not bad, from a gambling/probability perspective. However - as a value store, this variability is terrifying. I can put $1million into USD or AUD in a government-guaranteed savings account and feel very safe that this money will retain on the high side of 90% of its value or increase perhaps 5-10% value. The risk of total loss is near-zero. This gives me the comfort level needed to store real value in this way. BTC moving between $350 - $850 wildly with no apparent definitive reason (it's not like a stock where a company has made an announcement and rises rapidly/retains most afterwards), causes me to not want to use it as a store of value. The loss possibility is too high, the stress from experiencing the variance is too high.
  5. The Numeracy of it. $100 sounds nice, it's 100 of something right? $1 sounds OK, it's at least a whole number. It's quite obvious $1,000 is starting to become a lot, and $1,000,000 even more so. This is the reason that when you see a very devalued currency, it seems laughable. Like paying 36,721,941.06 bellarussian rubles per month in rent, doesn't seem 'right' to most people. Because we're used to the metric system. Bitcoin has a problem here for 'everyday' usage. Devs/enthusiasts wildly proclaim No! What! It's just 0.01 BTC! you can divide it up to 100,000 times (or whatever the resolution really is). BTC will reach $35,000 per coin! OK if it does. The problem's worse. 1BTC means I will spend for example, 0.0013428 BTC on petrol today. Does that really sound reasonable to you? I don't think society is quite at the point yet where it's like Black Mirror and we have a huge number of 'credits' on our screen. Even then, I'd want to see the decimal point somewhere else. Working for 3.5BTC per year for example, is not a nice sounding thing. OK sure you say, let's make another unit. Call it... mBTC. It will be 1,000th of a BTC. So in the future when BTC is $35,000 USD, one mBTC will be $3.50(USD equiv). The USD will inflate, more than BTC, since BTC is not inflationary. This potential increase in Bitcoin's value (some argue, increasing forever) means the required Unit for small daily purchases continues to change. mBTC will work for $35k BTC's but it won't work for $350k BTCs.
  6. I'm confused about the security. It's one thing to have a hash-based peer to peer system with an effective crypto scheme - but when the end user of this system, is subject to processes and systems that are by nature difficult to understand, this makes them prone to human-induced insecurity. A little like a highly-complex password policy on a network that results in users handwriting their password on a post-it note. Also at first I thought...Paper wallets (so I'm just printing my keys now? how the heck is that secure unless I lock it up in a safe? this is not security. Can anyone copy my keys and use them?). I don't need people to answer about how paper wallets work because I did end up reading up on it, I'm explaining my initial confusion and questions. Same went for electronic offline wallet systems, versus online wallets, versus exchanges that hold your coins, verus sending them to an offline computer. I mean really. If this was a commercial line of products the product manager would slap the developers and say STANDARDISE! how are you expecting people to seriously adopt this. Open platforms and software can (and should!) still create, drive, and adhere to standards.
Anyway, I digress, I still bought a small portion of some BTC (I mean..I'm not an IDIOT ;p). But - the things I went through - given I already know the general field quite well - and the thoughts, concerns, etc I had, do mean investing in this currency is going to be tough for a period of time that is perhaps longer than some of the estimates I see. I noticed its picking up a lot in the mainstream retail industry (places accepting BTC) which will help a lot. However the sorts of things listed above, do need to get sorted.
As an aside, not preaching here, but there's a reason most commercial companies don't allow their development teams to run the company, and I have to say these reasons are really showing through at the moment in the BTC arena. Just because as a group BTC supporters are generally anti-centralisation, doesn't mean you have to be anti-standards, or anti-organisation. Also to prevent unnecessary criticism and infighting, it's wise for there to be a common public image and an agreed upon set of standards, not this bickering, public infighting, dramatic stuff going on all the time.
Blockchains and their usage is stealing BTC's thunder a little lately too. I hope the BTC players can get things back on track a bit. The problems are making it all too easy for talented devs to go to Blockchain projects and leave the drama behind.
DISCLAIMER2: I apologise for misunderstanding, offensive comments, please don't steal my dog and burn my pet bird in retribution. Just throwing out there first impressions. I know I probably also misunderstand the 'security' of fiat and make many other potentially grave errors, but what I'm doing here, is communicating my first perceptions which I think will be shared by some, and unfortunately, for most people, perception=reality

The PHANTOM Technical Whitepaper[Version 0.1] The PHANTOM TeamPHANTOM Technical Whitepaper V2 pass2

We considered the attack strategy when the attacker tried to double the expenses by "over" the system speed. A “massive” attack means that, in order to double the expenses, the attacker tries to give the dual spending transaction a very large weight so that it will exceed the legal subtleties. When the allowed weight is unbounded, s policy is a threat to the network. As a solution, we can limit the transaction's own weight from above, or set it to a constant value. When the maximum self-priority of a transaction is m, the best attack strategy is to generate a transaction with its own weight, m, that refers to a dual-overhead transaction. When the INP is compared to the attacker's computing power, the ut flow of an "honest" transaction is large enough so that it is possible to estimate the likelihood of a double-spending transaction having a greater cumulative weight. formula). The attack method of constructing the "parasite chain" makes the height or score-based approval strategy obsolete because the attacker's site has higher value on these indexes than LE. The ultimate tangled. On the other hand, the PhantomTip selection algorithm described in Section 4.1 seems to provide protection against such attacks. The Phantom hint selection algorithm also provides extra incentives to prevent delay nodes. Resistance of F. to quantum computing It is well known that a sufficiently large quantum computer 35 can very effectively deal with problems that rely on trial and error to find a solution. Finding a "now" process, eating a bitcoin block is a good example. Since today, we must check an average of 268 non-CES to find a suitable hash that allows new blocks to be generated. (Everybody knows) TOM computer words need to handle INSTRON(N) operations to solve problems similar to the Bitcoin puzzle mentioned above. The same problem also requires INSTEM(N) operations on a classic Song computer. Therefore, the quantum computation r value is about 268 = 234 ≈ 17 billion times, which is more efficient than a classical computer on mining a bitcoin blockchain. In addition, it is worth noting that if a blockchain does not increase its difficulty, as a response to increased hash capabilities, the rate of isolated blocks will be increased. For the same reason, "heavy weight" attacks will also be more effective on quantum computers. However, as suggested in Section 4, limiting the weight from above will effectively prevent qua, as will computer attacks. This is obvious because the number of that need to be checked to find the right hash to issue a non-Ces transaction is not unreasonable. Age on Aver is about 38 years old. Therefore, the "ideal" quantum computer's efficiency gain is 34 = 81, which is quite acceptable. What's more, the algorithm used to implement the structure is such a time to find a random number. In order to obtain a wide range of applications, the applications on the chain need a platform that is flexible enough to meet the following requirements: Supporting millions of users to compete with companies such as ebay, uber, airbnb, and facebook requires high-performance technologies capable of handling tens of millions of active users. In some cases, the application may not reach a critical number of users, so a platform that can handle a large number of users is crucial. Cross-chain transaction of Free Usage Application developers of cross-chain transaction need to provide users with the flexibility to trade cross-chain transactions for free; users should not pay to use the platform or benefit from their services. A blockchain platform, which is freely available to users, may be used more widely. Developers and companies can develop effective cross-chain monetization strategies. Easy to upgrade and failback Businesses building blockchain-based applications need the flexibility to enhance the new features of their applications. The platform must support software and smart contract upgrades. All non-trivial software is affected by errors, even the most rigorous formal verification. The platform must be robust enough to fix bugs when bugs inevitably occur. Low latency A good user experience requires reliable feedback with a delay of no more than a few seconds. Longer delays can frustrate users and make applications built on the blockchain uncompetitive with existing NOs. N-block chain alternatives: the platform should support low latency for transaction latency. Due to the order-dependent steps of DPOS's large super nodes, some applications cannot implement parallel algorithms. Applications such as swaps need enough sequential performance to handle hi. Gh volume. Therefore, the platform should support fast sequential performance. Parallel performance Large applications need to divide workloads across multiple CPUs and computers. Consensus algorithm (BFT) The PHANTOM.IO software uses the only known decentralized consensus DPOS algorithm. This algorithm can satisfy the performance requirements of the application program on the blockchain, that is, the trust proof of delegation (DPO). Lander algorithm, using PHANTOM.IO software to hold tokens on the blockchain, can select block producers through a continuous approval voting system. Anyone can choose to join the block. Produce, and will have the opportunity to produce blocks, as long as they can persuade token holders to vote for them. PHANTOM.IO software allows blocks to be generated precisely every 0.5 seconds, and exactly one producer is authorized to generate blocks at any given point in time. If there is no editing time in the SCH generation block, then skip the block of that time slot. When one or more blocks are skipped, there is an interval of 0.5 or more seconds in the blockchain. Used in software, blocks are produced in n rounds (x blocks per unit, n producers per time). At the beginning of each round, n unique producers were decided by Toke's vote. n holder, the selected manufacturer arranges the order according to the agreement of n or more manufacturers. If a producer misses a block and has not produced any blocks in the past 24 hours, they will be considered to be removed from therein until they inform the blockchain that they intend to start producing blocks. Gain: it ensures that the network runs smoothly, by minimizing the number of blocks missed by the non-scheduled producers, which have proven to be unreliable. Under normal circumstances, the DPOS blockchain does not experience any bifurcation because block producers cooperate in producing blocks rather than compete. If there is a fork, the consensus will switch to the longest chain in automatic way. This method works because the speed at which blocks are added to a block fork is directly related to the percentage of block producers that share the same block. DPOS consensus: in other words, the length of the blockchain forks of more manufacturers grows faster than the lesser forks of manufacturers, because the more producers, the less the forks, and they are ignored. In addition, any block manufacturer should not produce two fork blocks at the same time. A block maker that prevents doing so is likely to be eliminated. This type of cryptographic evidence for dual production of m can also be used to automatically clear abusers. Byzantine fault tolerance was added to the traditional handicapped organization, allowing all producers to sign all blocks as long as no producer marks two blocks with the same time stamp or the same block height. A 15-minute painter has signed a block that is considered irreversible. Any Byzantine writer must sign two blocks with the same time stamp or block, resulting in treasonable cryptographic evidence. Under this model, an irreversible consensus should be reached within 1 second. Transaction confirmation A typical association of organizations of persons with disabilities has 100% of producers involved. After an average transaction time of 0.25 seconds, the transaction can be considered as confirming 99.9% certainty. In addition to disabled people's organizations, PHANTOM.IO also added asynchronous Byzantine Fault Tolerance (ABFT) to accelerate irreversibility. The aBFT algorithm provides 100% irreversibility confirmation within 1Seco. The software requires that each transaction contain a portion of the hash of the most recent block header. This hash provides two purposes: To prevent replay of transactions on forks that do not include reference blocks; and Signals when a particular user and their listed shares are placed on a particular fork. Over time, all users will eventually confirm the blockchain directly, which makes it difficult to fake chains because fakes cannot migrate transactions from legitimate chai. Haploid generation (code) Named permission levels For use in software, accounts can define named permission levels, and each permission level can be derived from higher level named permissions. Each named privilege level defines one privilege; one privilege is a threshold multi-signature check that consists of the keys and/or naming privilege levels of other accounts. For example, the “Friends” permission level on the account can be set to be controlled equally by any friend of the account. Another example is the Steem blockchain, which has three hard-coded named permission levels: owner, activity and release. Delivery licenses can only perform social actions such as voting and post-processing, while Active permissions can do everything except change the owner. The owner's permission is for refrigerated and can do all things. The PHANTOM.IO software allows each account holder to define their own hierarchy and grouping of actions. Permission mapping The PHANTOM.IO software allows each account to define the mapping between any other account's contracts/operations or contracts and their own named permission levels. For example, account holders can map ac. The counting holder's social media applies for the account holder's "friend" permission group. With this map, any friend can post the account holder’s identity on the account holder’s social media. Even numbers, they will put their account holders, they still use their own keys to sign the action. This means that it is always possible to determine which friends use the account and how to use it. Evaluation authority When an action of "Action" is passed, the PHANTOM.IO software will first check whether Alicepc's permission map. If nothing is then mapping. If no more matches are found, the map is assumed to point to the named permission group Once the mapping is identified, the threshold multi-signature process and the rights associated with the naming authority verify the signature authority. If it fails, it will move upwards. Go to parent permissions and eventually point to owner permissions. Default permission group The technology also allows all accounts to have an "Owner" group that can complete all tasks, and can do any "Activity" group other than changing the owner group. All other permission groups S are derived from "activity". Parallel Computing of Permission The permission evaluation process is "read-only" and changes to the permissions of the transaction do not take effect until the end of the block. This means that all keys and permission calculation transactions can be executed in parallel. In addition, it means that you can quickly verify permissions without starting expensive application logic, and these logic must be rolled back. Finally, it means that transaction privileges can be evaluated when pending transactions are received without having to re-evaluate them when applied. For all things considered, privilege validation represents a significant percentage of the calculations needed to validate transactions, making this a read-only and trivial parallel process can greatly improve performance. When replaying to regenerate a deterministic state from the operation log, there is no need to re-evaluate the rights. The block of facts contained in the known product is sufficient to skip this step, which greatly reduces the computational load associated with replaying a growing blockchain. Actions of mandatory delays Time is a key component of security. In most cases, it is not possible to know if the private key has been stolen until it is used. Time-based security is used when people have applications that require a key to be stored on a computer connected to the Internet for daily use. PHANTOM.IO software enables application developers to indicate certain operations that must wait for the minimum value of each operation, and they can be applied after being included in a block. During this time, they can be cancelled. When these operations are broadcasted, users can receive notifications via email or text messages. If they are not authorized, then they can use the account recovery process to restore their account d withdrawal actions. The delay required depends on how sensitive the operation is. Buying coffee may not be delayed and is irreversible within a few seconds, while buying a house may require a 72-hour clean-up time. It may take up to 30 days for the entire account to be handed over to the new control. The actual delay is chosen by the application developer and the user. Application deterministic parallel execution Blockchain consensus depends on deterministic (repeatable) behavior. It means that all parallel executions must be freed from the use of mutexes or other locking primitives. Without locks, there must be some way to ensure that transactions that can be executed in parallel do not produce ambiguous results. Software designed in 2018 will run a single thread, but it contains the data structures necessary for future multithreaded, parallel execution. Based on PHANTOM.IO software, once the parallel operation is enabled, the task of the block manufacturer is to transfer the actions to independent fragments so that they can be evaluated. The schedule is the output of the block producer and will be executed, but the process of generating the schedule is not deterministic. This means that block producer S can use parallel algorithms to schedule transactions. When part of the parallel execution means that when a script generates a new Action, it will not be delivered immediately, but it plans to deliver it in the next cycle. The reason is that it cannot be Ivered immediately because the receiver may actively modify its state in another fragment. Minimum communication delay Delay is the time it takes for receiving a response after an account sending an Action to another account. The goal is to enable two accounts to exchange operations back and forth in a single block. There is no need to wait 0.5 seconds between each action. To achieve this, PHANTOM.IO software divides each block into loops. Each loop is divided into fragments and each fragment contains a trans-list of actions. Each transaction contains a set of operations to be delivered. This structure can be visualized as a tree in which alternating layers are processed sequentially and in parallel. Region Cycle (order) Fragments (parallel) Transaction (order) Action (order) Receiver and notification account (parallel) Transactions generated in one cycle can be delivered in any subsequent cycle or block. The block generator will always add a loop to the block until the maximum wall-clock time passes or there is no n. EW generates the transaction to be delivered. You can use static analysis of blocks to verify that in a given period, no two fragments contain transactions that modify the same account. As long as the invariants remain unchanged, the block ca will remain unchanged. n Processes by running all fragments in parallel. Read-only operation handler Some accounts may be able to handle a pass/fail based operation without modifying their internal state. If this is the case, these handlers can be executed in parallel as long as they are read only. The Ly operation handler for a particular account is contained in one or more shards within a specific period. Multi-account atomic transactions Sometimes it is necessary to ensure that actions are delivered and accepted by multiple accounts. In this case, both operations are placed in one transaction and two accounts will be allocated. The same pieces and actions apply in sequence. Non-equilibrium partial evaluation Scale block chain technology requires that the components be modular. Everyone doesn't have to run everything, especially if they only need to use a small part of the application. Exchange application developers run full nodes to display Exchange status to users. This exchange application does not require the status associated with social media. The software allows any full node to select any subset of applications to run. If the application never depends on stat, operations passed to other applications will be safely ignored. Subjective best effort scheduling The software cannot force the vendor to pass any action to any other account. Each block producer makes its own subjective measurement of computational complexity and time. This applies to whether a transaction is generated by a user or automatically generated by a smart contract. In the boot blockchain using PHANTOM.IO software, at the network level, all transactions count toward the computational bandwidth cost based on the number of WASM instructions executed. However, each block producer using the software can use its own algorithms and metrics to calculate resource usage. When a block producer concludes that a deal or account has consumed a prop. When generating their own blocks, they simply reject the transaction; however, if other block producers consider the transaction, they will still process the transaction. In general, as long as a block producer considers a transaction to be valid, and all other block producers accept it under resource use restrictions, it may take 1 minute to find the producer's transaction. In some cases, the producer may create a block that contains a transaction that is out of the acceptable range. In this case, the next block producer may choose to reject block D. The tie will be broken by the third producer. This is no different from what would happen if a large block caused network propagation delays. The society has noticed a pattern of abuse. Remove ballots from hooligan producers. This subjective evaluation of computational costs has forced people to accurately measure the time to run. With this design, there is no need for PRESI. Calculating directives greatly increases the opportunity for optimization without breaking the consensus. Proof of integrity When using the proof of Merkle from an external blockchain, there is a big difference between knowing that all transactions are valid and knowing that no transactions have been skipped or OMI. Although it is impossible to prove that all the recent transactions are known, it can be proved that there are no loopholes in the history of the transaction. PHANTOM.IO Software Tool is achieved by assigning a serial number to each operation passed to each account. Users can use these serial numbers to prove that all operations for a specific account have been processed. And they are processed in order. Conclusions PHANTOM.IO software is designed based on proven concepts and best practices and represents the basic progress of blockchain technology. The software is part of the overall blueprint. For a blockchain society with global scalability, decentralized applications can be easily deployed and managed.
