Bitminter now has version-rolling ASICBoost support on all mining servers.

This means your DragonMint miners, and other future ASICBoost miners, will run full speed on Bitminter.

A big thanks to philipma1957 for helping with testing - it is much appreciated!

I believe we are the fourth pool to add this. It is still not supported by most pools.

Yes, there was just some BCH added to your account - nothing removed. As usual you can see all changes on your account under "my account" -> "transaction history" in the website menu.

Google is "helping" you. Go to google.com and log out from there, then go back to bitminter.com and try again. This time Google will ask you which Google account to use, because you logged out of Google.

You're either logging in with the wrong Google account or you didn't log in for several years and missed Google's transition from OpenID 2.0 to OpenID Connect.

Please use the contact form on the website to ask for help with this and we'll figure it out.

Looks like a repeat of a couple weeks back. AOL's OpenID server having intermittent issues.

If you would like a different type of login added to your account, contact support@bitminter.com

BCH (bitcoin cash) has been credited to accounts equal to their balance of BTC at the time of the fork (2017.08.01)

You can cash out your BCH using "my account" -> "send coins" in the website menu. First click "BCH" on that page. You will need to use a CashAddr style address. If your BCH wallet does not support CashAddr then you can use the address converter at https://cashaddr.bitcoincash.org/ - but note: DO NOT put a bitcoin address into this calculator. It is for BCH addresses from BCH wallets that do not support the new CashAddr addresses yet.

What is bitcoin cash?

Bitcoin cash (BCH) is a fork of Bitcoin (BTC). You can read more about it at https://bitcoincash.org/
It shares a transaction history with bitcoin up to the time of the fork. If a wallet had a bitcoin balance at the time of the fork then it is possible to unlock the same amount on the bitcoin cash blockchain. For every BTC prior to the fork there now exists a BCH.

Does this mean Bitminter will support all other forks?

No. Cash out your BTC to a wallet where you control the private keys, then you can take part in the forks you want. Always cash out. Take control of your coins.

Are we mining BCH now?

No. We are currently only mining BTC, plus NMC through merged mining with BTC.

It says my address is not a valid BCH address?

If you are trying to send BCH to a BTC wallet, stop immediately and get a BCH wallet you can send the coins to.

If you are using a BCH wallet that only supports legacy addresses, use the converter at https://cashaddr.bitcoincash.org/ to get a CashAddr type address.

If you are using a multi-currency wallet or online service that supports multiple currencies, make sure you are sending to a BCH address. Use the converter if necessary, but double check that you have picked a BCH address, not a BTC address.

I'm not working on more notifications yet.

But what I'd like to do is make a separate page with email preferences where you can choose what types of email you want to receive, and then add several new types of notifications.

One issue with sending more emails is that users of Microsoft email services (msn.com, outlook.com, hotmail.com, live.com) frequently report them as spam. They type in their email address when they create their account. Then they receive the email confirmation message and immeditaly report it as spam. This has gotten Bitminter banned from delivering email to these Microsoft services several times already.

Maybe all the toggles can default to off for Microsoft users.

Bitminter now supports Bech32 addresses. So you can cash out to native segwit addresses - those are the addresses starting with "bc1" as specified by BIP-173.

Note that many services don't support Bech32 yet. It's especially annoying that some block explorers don't appear to be able to look them up yet. But I'm sure this will change soon.

If you are using Bitcoin Core then you need to upgrade to version 0.16.0 to get Bech32 support.

More about Bech32:

It's not supported by Bitminter client. But you can use it at the Bitminter mining pool the same way you use it at any other pool. Probably with cgminer or bfgminer?

Damnit! I think I broke it. I'll have another look at it.

Thanks for letting me know

Yeah, I should probably add notifications by email. Currently there is the Yo thing, and also notifications in the chat.

Yeah, at that point you mine for fees.

Today you earn new coins + transaction fees. Once all coins have been created, the "new coins" will be zero. So transaction fees are then 100% of your earnings from mining.

Some miners used to wear lucky underwear. Perhaps what you are doing will work better to improve our luck.

Yes, the only way to get any income with mining is to find/create new blocks. The income from mining a block is the combination of new coins that are created with the block, and the transaction fees of all the transactions in the block.

When you create a new transaction because you want to pay someone, it just floats around on the bitcoin peer-to-peer network. It is not part of the permanent ledger that is the blockchain. To anyone observing the transaction it is merely an intention to pay, which may take place in the future. Another transaction sending the same coins somewhere else might become part of the blockchain instead. This transaction is considered unconfirmed. You might trust it to pay a cup of coffee, but not a car (certainly not a Lambo).

So you offer a transaction fee on your transaction, to incentivize miners to include it in a block. The miners mine a block with your transaction, they get paid and now your transaction is in a block. Your transaction is in the block at the top of the chain. It has 1 confirmation, which is the block it is in. It's somewhat more trustworthy. But what if there is a blockchain fork and the other side of the fork becomes the longest chain? Then this transaction may yet disappear. This becomes less likely as more blocks are added on top of the block with the transaction. Once there are 5 additional blocks the transaction is said to have 6 confirmations. This is often considered to be the point where you can assume it is a permanent part of the blockchain. The recipient can trust that the coins you sent them are now theirs. This is what you paid the miners for.


Currently the difficulty is almost 3.3 trillion (called billion in continental europe). This means it takes a tremendous amount of work to find a block. On average it takes 3.3 trillion (mining pool proofs of) work. If the difficulty goes up the average time to find a block goes up. If our hashpower goes up the average time to find a block goes down.

Compared to 3 months back, the difficulty is now 2.5x what it was. Our hashpower is 3.5x what it was. So our average time to find a block has gone down. Further increasing the hashpower will further reduce the time to find blocks. It makes all rounds (time between blocks) go by faster, but most importantly of course the long and unlucky ones.

Our amount of work since the last block is over 10.6 trillion. That's more than 3x the difficulty and is certainly bad luck. This is fairly rare.

The worst block we've had took an amount of work that was 11x the difficulty. This is the awful block of which we do not speak. Except I just did. Thankfully something like that is extremely rare.

This long round is getting rather annoying and several people have been trying to end it by renting extra hashpower, but had problems getting that to work.

Mining servers have been updated today to make rentals run more smoothly on Bitminter:

• Default worker difficulty is now 4096
• Auto detect Nicehash worker and use minimum difficulty 1 million
• Minor tweaks to difficulty auto adjustment algorithm

Yeah, those transaction fees, we get them when we mine a block. There's noone on the web collecting them. And noone is earning them in between blocks. When we create a block we put transactions in the block. We earn the new coins created in the block, plus the transaction fees for the transactions we put in the block.

It depends how the shifts look when the block is found. If we find a block now and you have work in 9 shifts then you get paid for those.

Your work gets registered in shifts. When someone mining in the pool finds a block you get paid. Your share of the coins from the block depends on your share of the work done in the last 10 completed shifts. If you stopped mining then after a while there will be new shifts where you have done no work.

No. Maybe it's complaining about low difficulty? Try setting the minimum difficulty on the worker you are using for rentals to 1048576. On the workers page, click the gear icon to access these settings.

You can see the total amount of work in the live stats. The best share of past rounds is always the block we found. We don't record a "best share so far" for the current round though.
