Funding the future with the future of currency
**About the Einsteinium Foundation** The Einsteinium Foundation was created to help, in any small way it can, raise funding for cutting edge scientific research. To this aim we created Einsteinium, a new crypto currency (similar to Bitcoin), to gather funds that can be distributed to projects the community chooses. Combined with donations from the community at large we will help fund some of the most innovative projects currently under-way or help seed those waiting to start.
The core developers are pleased to present the 126.96.36.199 Elizabeth milestone leisure release. This is a leisure release primarily aimed at non-mandatory items and bug fixes leading up to the Fern mandatory milestone release. This release also enables us to whitelist teams other than Gridcoin as a stepping stone for the implementation of no team requirement in Fern. Enjoy! https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/188.8.131.52 Changelog...
Add freedesktop.org desktop file and icon set #1438 (@a123b)
Hey guys, I thought I would put together an in-depth tour of the Gridcoin wallet software for all of our recent newcomers. Here I'll be outlining all the features and functions the windows GUI wallet has to offer, along with some basic RPC command usage. I'll be using the windows wallet as an example, but both linux and macOS should be rather similar. I'll be including as many pictures as I can as embedded hyperlinks. Edit: Note that since I originally made this there has been a UI update, so your client will be different colors but all the button locations are in the same place. This is my first post like this, so please forgive me if this appears a little scatter-brained. This will not cover the mining setup process for pool or solo miners. When you launch the wallet software for the first time you should be greeted with this screen.
If you're a pool miner or investor, press cancel.
If you're a solo miner, enter your email you used to sign up for projects and press OK.
If you're not sure or haven't decided yet, press cancel. We can come back to this later.
After that prompt, you should be left sitting on the main overview tab with several fields on it. From top to bottom:
Available: All coins available to be sent or staked (I'll cover this term later).
Stake: All coins that are currently staking.
Unconfirmed: All coins that have been received and have not yet received 110 confirmations.
Total: All coins in your wallet. (The sum of the above fields)
Blocks: How many blocks your client has in it's chain. Your wallet just started syncing with the network so this number will be low.
Difficulty: How difficult it is for someone to stake the next block.
Net Weight: An estimate for how many coins are staking on the entire network.
Coin Weight: How many of your coins that are currently staking.
Magnitude: A quantifier for how much work you put in mining. For solo miners only. For pool miners, this value will always be 0.
Project: Displays the projects you're working on, one at a time. For solo miners only. For pool miners, this will always say "INVESTOR".
CPID: Cross Project Identifier. Used to keep track of users across projects. For solo miners only. For pool miners, this will always say "INVESTOR".
Status: Displays various status messages.
Current Poll: Displays the latest poll.
Client Messages: Displays various client messages.
Now onto the other tabs on the left side. Currently we're on the Overview tab, lets move down to the Send tab. This tab it pretty self-explanatory, you use it if you want to send coins, but I'll go over the fields here:
Pay To: Enter a valid gridcoin address to send coins too. Gridcoin addresses always start with an S or and R.
Label: Enter a label here and it will put that address in your "address book" under that label for later use. You can leave it blank if you don't want it in your address book.
Message: Enter a message here if you want it attached to your transaction.
Amount: How many coins you want to send.
Add Attachment: Leave this alone, it is broken.
Track Coins: This doesn't do anything.
Now down to the Receive tab. Here you should have a single address listed. If you double click on the label field, you can edit it's label.
New: Generate a new address.
If you click on an address, the rest of the options should be clickable.
Copy: Copy the selected address to your clipboard.
Show QR Code: Show a scan-able QR code for the selected address.
Sign Message: Cryptographically sign a message using the selected address.
The Transactions tab is pretty boring considering we have no transactions yet. But as you can see there are some sorting tools at the top for when you do have transactions listed.
ADDRESS BOOK TAB
The Address Book is where all the addresses you've labeled (that aren't yours) will show up.
Verify Message: Verifies a message was signed by the selected address.
The rest of the functions are similar to the functions on the Receive tab.
Onto the Voting tab. There wont be any polls because we aren't in sync yet.
Reload Polls: Pretty self-explanatory, I've never had to use this.
Load History: By default, the wallet will only display active polls. If you want to view past polls you can use this.
Create Poll: You can create a network-wide poll. You must have 100,000 coins as a requirement to make a poll. (Creating a poll does not consume the coins)
Display coin control features (experts only!): This allows you to have a great deal of control over the coins in your wallet, check this for now and I'll explain how to use it further down. Don't forget to click "Apply".
ENCRYPTING YOUR WALLET
Now that all of that is out of the way. The first thing you'll want to do is encrypt your wallet. This prevents anybody with access to your computer from sending coins. This is something I would recommend everyone do. Go to Settings > Encrypt Wallet and create a password. YOU CANNOT RECOVER YOUR COINS IF YOU FORGET YOUR PASSWORD. Your wallet will close and you will have to start it up again. This time when it opens up, you should have a new button in the bottom left. Now if you want to stake you will have to unlock your wallet. Notice the "For staking only" box that is checked by default. If you want to send a beacon for solo mining or vote, you will need to uncheck this box.
GETTING IN SYNC AND ICONS
Before we continue, Let's wait until we're in sync. Depending on your internet speeds, this could take from several hours to over a day or 2. This can be sped up by using Advanced > Download Blocks, but this can still take several hours. This is what an in-sync client should look like. Notice the green check to the right of the Receive tab. All of these icons give you information when you hover your mouse over them. The lock The arrow tells you if you're staking. If you aren't staking, it will tell you why you're not staking. If you are staking it will give you an estimated staking time. Staking is a very random process and this is only an estimate, not a countdown. The connection bars tell you how many connections to the network you have. The check tells you if you're in sync.
WHAT IS STAKING?
Now I've said "stake" about a million times so far and haven't explained it. Gridcoin is a Proof of Stake (PoS) coin. Unlike bitcoins Proof of Work (PoW), PoS uses little system resources, so you can use those resources for scientific work. PoS works by users "Staking" with their balance. The higher the balance, the higher the chance to create, or "stake" a block. This means you need to have a positive balance in order to stake. Theoretically, you can stake with any amount over 0.0125 coins, but in practice it's recommended to have at least 2000 coins to reliably stake. Staking is important for solo miners, because they get paid when they stake. Pool miners don't need to stake in order to get paid however. So if you want to solo mine, you'll need to buy some coins from an exchange or start in the pool first and move to solo when you have enough coins. In addition to Research Rewards for miners, anyone who holds coins (solo miners, pool miners, and investors) gets 1.5% interest annually on top of your coins. So it can be beneficial for pool miners to stake as well. Here is a snippet of what a research rewards transaction looks like from my personal wallet. I have a label on that address of "Payout address" as you can see here.
UTXOS AND COIN CONTROL
At this point you'll need some coins. You can use one of our faucets like this one or this one to test coin control out. First let me explain what a UTXO is. UTXO stands for Unspent Transaction Output. Say you have an address with 0 coins in it, and someone sends you 10 coins like I've done here. Those 10 coins are added to that address in the form of a UTXO, so we have an address with one 10 coin UTXO in it. Now we receive another 5 coins at the same address, like so. Now we have an address with one 10 coin UTXO and one 5 coin UTXO. But how do we view how our addresses are split up into different UTXOs? Earlier we checked the "Display coin control features" box in Settings > Options > Display. Once that's checked you'll notice there's another section in the Send tab labeled "Coin Control Features". If you click the "Inputs" button, you'll get a new window. And look, there's our 2 UTXOs. All UTXOs try to stake separately from each other, and remember that the chance a UTXO has to stake is proportional to it's size. So in this situation, my 10 coin UTXO has twice the chance to stake as my 5 coin UTXO. Now wallets, especially ones that make a lot of transactions, can get very fragmented over time. I've fragmented my wallet a little so I can show you what I'm talking about. How do we clean this up? We can consolidate all this into one UTXO by checking all the boxes on the left and selecting OK. Now pay attention to the fields on the top:
Quantity: The total amount of UTXOs we have selected.
Amount: The total amount of coins we have selected.
Fee: How much it would cost in fees to send all those UTXOs (more UTXOs = more transaction data = more fees)
After Fee: Amount - Fees.
Bytes: How large the transaction is in bytes.
Priority: How your client would prioritize making a transaction with this specific set of UTXOs selected had you not used coin control.
Low Output: If your transaction is less than 0.01 coins (I think).
custom change address: You can set the address you get your change back at, by default it will generate a new address.
So let's fill out our transaction so we end up with 1 UTXO at the end. In "Pay To:" Just put any address in your wallet, and for the amount put what it has listed in the "After Fee" Field. Just like this. Notice how we get no change back. Now click "Send", we'll be prompted to enter our passphrase and we're asked if we want to pay the fee, go ahead and click "Yes". Now if we go back to the Overview tab we get this funky icon. If you hover your mouse over it, it says "Payment to yourself", and the -0.0002 GRC is the network transaction fee. (Ignore the first one, that was me fragmenting my wallet) Now if we look at the Coin Control menu, we can see that we've slimmed our wallet down from 7 UTXOs to 1. Now why would you want to use coin control? 2 Situations:
UTXOs less than 0.0125 coins cannot stake. So you can combine a lot of tiny, useless UTXOs into 1 bigger one that can stake.
After a UTXO stakes, it cannot stake for another 16 hours. So if you have 1 large UTXO that is big enough to stake more than once every 16 hours, you can split it into smaller UTXOs which can allow you to stake slightly more often.
By default, the wallet will always generate a new address for change, which can make your wallet get very messy if you're sending lots of transactions. Keep in mind that more UTXOs = larger transactions = more fees.
Sidenote - When you stake, you will earn all research rewards owed reguardless of which UTXO staked. However, you'll earn the 1.5% interest for that UTXO. Not your whole wallet.
A fork is when the network splits into multiple chains, with part of the network on each chain. A fork can happen when 2 blocks are staked by different clients at the same time or very close to the same time, or when your client rejects a block that should have been accepted due to a bug in the code or through some other unique circumstance. How do I know if I'm on a fork? Generally you can spot a fork by looking at the difficulty on your Overview tab. With current network conditions, if your difficulty is below 0.1, then you're probably on a fork. You can confirm this by comparing your blockhash with someone elses, like a block explorer. Go to [Help > Debug Window > Console]. This is the RPC console, we can use to do a lot of things. You can type help to get a list of commands, and you can type help [command you need help with] (without the brackets) to get information on a command. We'll be using the getblockhash [block number] command. Type getblockhash [block number] in the console, but replace [block number] with the number listed next to the "Blocks:" field on the Overview tab. This will spit out a crazy string of characters, this is the "blockhash" of that block. Now head over to your favorite block explorer, I'll be using gridcoinstats. Find the block that you have the hash for, use the search bar or just find it in the list of blocks. Now compare your hash with the one gridcoinstats gives you. Does it match? If it matches, then you're probably good to go. If it matches but you still think you're on a fork, then you can try other block explorers, such as gridcoin.network or neuralminer.io. If it doesn't match, then you need to try to get off that fork. How do I get off a fork?
Just wait for an hour or two. 95% of the time your client is able to recover itself from a fork given a little time.
Restart the client, wait a few minutes to see if it fixes itself. If it doesn't restart again and wait. Repeat about 4 or 5 times.
Find where the fork started. Using the getblockhash command, go back some blocks and compare hashes with that on a block explorer so you can narrow down what the last block you and the block explorer had in common. Then use reorganize [the last block hash you had in common]. Note that reorganize takes a blockhash, not a block number.
A listening node is a node that listens for blocks and transactions broadcasted from nodes and forwards them on to other nodes. For example, during the syncing process when you're getting your node running for the first time, you're downloading all the blocks from listening nodes. So running a listening node helps support the network. Running a gridcoin listening node is simple. All you need to do is add listen=1 to your gridcoinresearch.conf and you need to forward port 32749 on your router. If you don't know how to port forward, I'd suggest googling "How to port forward [your router manufacturer]".
I'm new to the Gridcoin scene, but I did some Bitcoin mining a few years back, I stopped prematurely now seeing what BTC is worth... Anyway I got interested in Gridcoin when I found it and Boinc, with the whole furthering science option and gaining cryptocurrency by crunching in the process, very cool. Right now I've been pool crunching somewhat on and off for maybe the last week, mainly using my "higher end" cough laptop, right now the pool reports I'm racking in about 1 mag at .25 GC a day. Now I'm expecting/hoping for my mag to reach 2-3 (or even higher?) over the next few weeks if I keep at it. Currently I've had one payout from the pool of just under one GC.. But I found a site today claiming to freely give 3 free GC, so I'm hoping by my next payout to have 5 GC in total, and I'm planning on using my wallet for staking purposes for now. TLDR Which leads to my question, what does staking do for Gridcoin, and what does it matter to me? Am I rewarded a certain amount of coin when I stake a block? I made a receiving address to my wallet in case anybody feels generous and wants to help a newbie out :) S8D9F8ggxUs4jpQj4JLndet3q2knXpaRBg For Science and Exploration!
I bought bitcoin in the paradigm of free transactions being included whenever and moderate fee transactions being included next block. That has already changed with htting the max block size.
Thorbinator in /btc at https://www.reddit.com/btc/comments/3wnb3t/is_it_rbtc_or_rbigblocks/cxxu4gu PSA: Mining code change in Bitcoin Core is eliminating free/low fee transaction confirmation The free transaction system in Bitcoin is a beautiful thing. The miners are already getting paid well through block rewards and as long as the cap isn't being hit, there's not a particular disincentive to include it, so a lot of miners end up including them "just because" since it's built into the system by default and makes some sense (they're mining the coins too; it's nice to be able to move them freely or at least cheaply (they often generate some of the largest transactions and thus end up paying fees themselves regularly unless they deliberately mine their own transactions instead of paying fees)). All clonecoins (with the possible exception of LTC at some very peak times, but AFAIK they're still generally far below cap and thus not affected either) still have this. Although, actually, come to think of it, DOGE has already changed away from this themselves iirc: They have a minimum transaction fee of 1 DOGE I thought, and it accumulates with 1 DOGE being the basic unit for fees, part of why fractional DOGE aren't tipped. So what are the best clonecoins to give good free transaction support? We would want to have a shorter block time (1 min if possible; 2.5 min acceptable) in my opinion to increase throughput and consistency of performance. We would not want it to be facing current demand with an insistence on maintaining the cap (excludes LTC). We would not want it to have already made moves to higher transaction fees (excludes DOGE). Interlude: why clonecoins? The block size cap is exactly where clonecoins can shine: what is fundamentally a quibble upstream means that having code which is substantially similar is an advantage: the upstream code is trusted and reliable, with known faults which can be anticipated and mitigated and fixed with small, easy changes. There's a substantial base of code and knowledge which supports the same technology and be trivially (compared to original development) imported. There's also the classic gold:silver:copper argument which I find quite convincing and also illustrated in the current case. Consider transaction fees: as we go from BTC to LTC to DOGE we reduce transaction fees but also reduce marketcap, liquidity, and long-term "certainty". Essentially we pay something else in exchange for these reduced fees, which is taking a risk holding something which isn't gold. I think an issue like "Free Transactions" is an excellent one upon which to make a stand. I think it is clearly reasonable to allow a hodler to be able to move their coins every couple weeks or so for free or cheaply, just as a basic courtesy, and within a few months at absolute worst case and to work hard to avoid facing a situation where could not in practice be moved quickly with low to moderate fees (1 hour being slow, 10 minutes being reasonable, 1 minute or less being faster than needed generally but nice). In practice, it's nice if free transactions can work practically every block, or at least every hour, but I think that's probably unlikely to be possible in the long-term for a popular coin. And it just makes for a lot of nice use-cases which otherwise aren't possible, things which are considered "spam" by some upstream networks: colored coins, dust, tests, whatever it may be. I think it's great for people to be able to play around with their coins. If they want to make some dust and the miners have the excess capacity to mine it, so be it. There are enough solutions in place or already planned upstream for dealing with chain / utxo pruning and efficiency that I think it can be easily handled. If BTC wants to turn away demand, everyone else should be preparing for rain rather than planning to following such a brilliant upstream strategy. This has been the best thing to happen for LTC since, well BTC. And LTC hasn't even really done much to encourage long-term adoption on that basis, given that there are stated plans not to raise the block cap. DOGE as mentioned already has minimum fees but otherwise is a relatively good choice in this respect (1 DOGE minimum fee being like 30 satoshi right now is not a crazy amount to contemplate; even at "large" 20 DOGE transaction fee <1000 satoshi transaction fee looks to be rather competitive with a normal BTC transaction fee for the near future at leats). So, attempting to answer my own question by going down the coinmarketcap rankings (market cap as rough approximation for liquidity / market strength which is certainly another important store-of-value consideration, although it has important drawbacks as well, not addressed herein) and ruling out anything that's not a fairly basic clonecoin, just for the purposes of looking for "Bitcoin with actual commitment to free transactions" among top clonecoins:
Bitcoin - nope
Ripple - not a clone
Litecoin - not dedicated to free transactions (not raising cap)
Ethereum - not a clone
Dash - not a clone (arguable, but going to consider it out of scope here)
Dogecoin - not dedicated to free transactions (still good for cheap transactions)
Stellar - not a clone (of Bitcoin)
Peercoin - worth consideration; its market cap is almost $10 million. It has PoS instead of PoW, which is generally considered either a significant advantage or a significant disadvantage depending on who you ask. I'm not certain of their transaction fee policy, but iirc apart from PoS they stayed pretty much a true clonecoin, so if it's still got the old Bitcoin free transaction rules, it's good.
Bytecoin - Large supply coin, which might be good for this. $5 million market cap; 7 sat unit price. And transactions on a recent block with 0.01 BCN fees So with (far) less than 1 satoshi transactions, I think that would be the closest to "free transactions" so far in this list. Perhaps this also explains some of its popularity. Oh, oops, I hadn't remembered / realized that this was based on CryptoNote, Not technically a clonecoin then. Otherwise looks like a very good contender for "cheap transactions", although possibly not "free transactions".
Monero - not technically a clonecoin (of Bitcoin).
NuShares - not a clonecoin
Rubycoin - Don't really know anything here but coinmarketcap has it marked as not-mineable. It's gone from being a <2000 satoshi coin to being around a 45000 satoshi coin from August to now. Strangely the last 100 blocks only had 2 transactions in each block, which I think with this type of PoS is the minimum. Another block just generated with 3 transactions. Okay, so they have a 0.0001 RBY transaction fee, which would be 4.5 satoshi at this point.
GridCoin - I'm going to go with "not a clonecoin" here, but I'll look at it anyhow because I like it. ~$3.6 million market cap, which ain't bad. I can't quickly find the transaction fees here. A guess of 0.0001 would put it at 0.2 satoshi transactions which would be fairly impressive for cheap transactions. I don't see any immediate references to free transactions though.
Alright, that's more than enough for this installment of what was originally going to be a reply in /btc, then turned into a post for /cryptocurrency. If people show some interest, I'll definitely go through more of the top market cap coins looking for any clonecoins which have a commitment to free transactions. So far I'd say I haven't seen any in the top 25 on coinmarketcap, but I could certainly be missing something, and if so, please feel free to let me know! Also, we need a rambling / rant flair. I will suggest that now. Edit: Apparently AutoModerator had labeled this spam. ;-( Using my new powers to declare it's not spam.
