Almost all of your computing power can be directed at beneficial scientific and medical research while crunching Gridcoin.
See the list of Advantages & Features.
In Gridcoin, work units are given out by distributed project nodes within the BOINC network which uses their independent calculation to reward research. Gridcoin compares participants in each project by their subsidiary credits earned in BOINC to measure performance in relation to dynamic inner project network average.
BOINC has been rewarding scientific work units in a credit system since
Security in Gridcoin is derived from Blackcoin’s industry-leading Proof-of-Stake.
Consult these guides:
If you are in the pool, this is normal. If you are attempting to solo-stake, go through the following:
If you have just begun your BOINC journey it is quite possible your work units haven’t been verified by the necessary servers. Don’t Panic, Gridcoin is a game of patience. Just relax, take a day or two, and see if the problem persists. If so, proceed to the following steps.
To ensure your wallet is fully unlocked, lock your wallet with a passphrase (make it LONG, a password manager like KeePass is recommended) and then unlock it with “for staking only” UNticked.
Next, go to Help -> Debug Window, go to the Console tab and type
advertisebeacon
without the quotes.
This will (if successful) send a small transaction at the cost of 1 GRC. This should add your CPID with the next superblock.
To see if your CPID is included, go to the Console and type beaconreport
.
If your CPID is not included, wait for the next superblock. In case your
CPID isn’t included after a few superblocks, try resending your beacon
(advertisebeacon
).
Lock your wallet again, but this time unlock it with “for staking only” ticked.
Please check the config file page
If you are using the GUI you will see a transaction with a gold icon.
You can also lookup your address on a block explorer.

Magnitude is calculated separately for each project. When calculating research rewards, a user’s magnitude across every project is added together.
The reason for this is most likely that you have to resend your beacon,
which should be done every 6 months. For this either unlock your wallet
so that it sends automatically or type advertisebeacon
in the
console.
RAC is a rolling average over the past month. It is weighted to increase the value of more recent contributions. Gridcoin relies on the RAC values provided by the project to calculate your magnitude.
However, you can’t just compare your RAC between projects because different projects use different systems for how they calculate the RAC. Because of this the magnitude calculation also takes into account the total RAC for other crunchers earning Gridcoin.
Depending on your hardware you may want to keep away from some projects.
You can see estimated magnitude levels for your hardware here: http://quickmag.ml/cgi-bin/script.cgi
Unfortunately, data for some whitelisted projects like WCG are not available so they won’t be included in the estimate.
There are also overrun CPU projects or projects that do not provide constant work unit (WU) flow.
Try different projects and see whether your hardware can keep up a high magnitude. You can review your outcome magnitude in the wallet.
Anyway, if you like a project you should still support it, to keep the BOINC spirit up.
Additionally, you might not want to use your CPU to crunch for projects with GPU WUs. You can find CPU only projects by visiting the BOINC project list and looking out for projects that have the Radeon or Nvidia icon.
Yes, there are currently 2 operational pools:
That is perfectly normal when pool-mining you do work for the pool’s account and as a reward get transactions from the pool for the work you did. Because of this you do not work for your own CPID and have no magnitude.
Make sure you remove all existing projects, which use your account, from the BOINC manager before syncing to the pool.
Proof of Stake rewards will give you 10 GRC for each block you stake. If you are not in investor mode you will also receive your BOINC rewards on top of the 10 in the same block.
It takes 16 hours for GRC to become mature from the time of arrival in your wallet. After a specific set of coins have Staked, they will need to mature again for 16 hours before they can Stake again.
You may have a balance reserved in stake. If this ever happens to you do this in the console:
reservebalance true AMOUNT
Where AMOUNT is the amount you want to send
Wait for a few blocks
Then send it.
Yes. It means that those coins are currently on cooldown so they aren’t able to stake for the next 16 hours.
Yes, but you have to unlock it first. It’s recommended to unlock it “for staking only”.
The console walletpassphrase command does what clicking the lock button does.
To lock Type
walletlock
to unlock for a certain time type
walletpassphrase PASSWORD TIMEOUT
to unlock type
walletpassphrase PASSWORD
to unlock only for staking type
walletpassphrase PASSWORD TIMEOUT true
walletpassphrase "your passphrase in double quotes" timeout true
where timeout is the number of seconds, e.g. 10000 and true is a toggle that unlocks the wallet for staking only.
When you stake on a fork, the stake you see is not actually legitimate. When your wallet figures out that it is on a fork, you will see these rewards disappear as the wallet corrects itself. This process happens automatically. While frustrating, once off of the fork, you are still able to stake again.
Running “projects” in the console will list all the whitelisted projects you could possibly contribute to that would help your Gridcoin Research wallet.
That means you aren’t participating in those projects or the e-mail address you have in the conf file doesn’t match the e-mail address used in your BOINC manager on that machine. For every project you join, you also have to join the Gridcoin team on that project. Any changes about e-mail address on a project or team membership on a project take around a day to propagate.
You only need one wallet for each BOINC account/CPID (Cross Project Identifier). Optionally, you can use an account manager to help maintain projects in under CPID and avoid CPID splits. Your reward is based on the credit on your CPID. You can point as many machines and resources to a single account as you want and only need a single wallet to receive your reward. You do have to set “email=” in the config file to your BOINC email and must be running the wallet on a machine that has BOINC installed and is associated with all BOINC projects you would like to get credit for (they can be set to not retrieve new work) and each project must show at least some RAC on that machine (press “Update” in the BOINC software when a project which shows 0 contribution is selected).

We used to support detaching but a vote was made to calculate the magnitude on every project you still have valid RAC on; so GRC does not support detaching projects (it was supposed to prevent gaming the system). There is no difference if you score 0 on a project, as all are taken into account equally.
If you insist on not being paid for a specific project, change your team away from a recognised team for that project.
If you have some BOINC credits, you are in a recognised team and your email is correct in the gridcoinresearch.conf file. You should see a list of
your magnitude in each project when entering “explainmagnitude” to the debug console of the wallet (Help -> Debug Window -> Console). It may take 24-48 hours for new accounts to be populated.
A staking hash that is generated that is LESS than the target will stake. So the smaller the target (higher the diff) the LOWER the probability of staking.
This also means that diff is directly proportional to that average net coins staking on the network.
TL;DR: When more coins are staking the difficulty increases which makes it harder to stake and vice versa.
The formulas to calculate diff may be found in section 2.1 of the staking bluepaper.
Create a shortcut that links to the actual GRC program in Program Files directory and add the function at the end of the target, then properly name them for the function to execute:
Example with -rescan option: Make a new shortcut to
"C:\Program Files\GridcoinResearch\gridcoinresearch.exe"
Add the command to execute at the end of the ‘Target:’ line like
"C:\Program Files\GridcoinResearch\gridcoinresearch.exe" -rescan
Rename the shortcut to something like ‘GRC rescan’.
Then go to Advanced and tick on run as Administrator.
From now on when you double click on it, it will execute that Command Line function.
This way it is simpler and faster for newbies than CLI and batch.
After you double click on the tx in the list, write down the block number (not hash).
Then do
showblock blocknumber
And compare the details with details from explorer.
If you do want to get a block by hash, you would have to:
getblockhash blocknumber
getblock blockhash
But that is a little longer
Download the installer from Github or your package manager and install over your previous installation.
Do not delete the data folder. This contains important data like your keys which let you access your coins.
The wallet has an automated backup in place that will make backups every 24 hours into the walletbackups folder inside of your data folder.
Different methods were discussed in the Gridcoin Community Classroom #003: https://www.youtube.com/watch?v=JxrjUwX5XvA
The quick and easy way.
If it still doesn’t start you can try using the -salvagewallet flag.
Just try to just wait it out the wallet should automatically fix itself.
If it still hasn’t gone up after a few hours try this:
You can also try running the wallet as an administrator.
There is also an official thread for sync problem if it didn’t work.
Compare your highest block number with the one listed at gridcoinstats.eu
When the explorer is clearly ahead of you (> 9 blocks) and increasing about every 90 seconds, your node is most likely on the fork. You can wait till it syncs or rebuild the blockchain.
When you are clearly ahead of the explorer and / or the explorer has stopped incrementing on a regular basis, it’s more likely that the explorer will sync up with you and your connected nodes at some point.
Ensure you are running the latest wallet version.
You can try using the snapshot which you can get Here.
While it downloads, delete the peers.dat in your data folder - you may have a bad peer group.
You can also try to reboot your router to attempt to get a new IP, to make sure you are not banned by good nodes because of earlier behavior.
First, install telnet for your respective os.
Then open your command box and enter telnet addnode-us-central.cycy.me 32749
. If there is no response, your Firewall might have blocked the
port. Otherwise, your configuration might be wrong or your node may have been
temporarily banned by the
network.
Make sure you’re on the latest wallet version.
Syncing may seem to take longer with growing blockchain. If you get stuck use ‘reboot client’
Gridcoin Classic was the first iteration of Gridcoin. Gridcoin classic is no longer used and all coins were converted to Gridcoin Research coins via Proof of Burn. The Burn process ended on April 20, 2015. If you missed the Burn deadline, your coins are now in the possession of the Gridcoin Foundation and can no longer be claimed.
Start the client with the -testnet flag.
Try running the client with “-rescan” or run the console command “repairwallet”.
Delete the content of the folder called ‘txleveldb’ in the data folder and restart.
