So I did the reindex-chainstate=1 and removed the pound sign. Now Bitcoin Core wallet is running again, but now it's starting back from 2009, which was the reason I was afraid I'd have to do.

I see. Let me try this one. Thanks.

How do I do the reindex-chainstate files?

Hi all,

I am having issues with starting my Bitcoin Core wallet on a Windows. I keep getting error stating: Error reading from database.

I've tried to uninstall and reinstall different BC version, still the same error and the wallet won't start. It was previously fully synced.

At the bottom of the debug log, it shows LevelDB error: Corruption block checksum mismatch: F:\Bitcoin\chainstate/3348075.ldb.

From reading on a couple of other posts with similar problem, it looks like the recommendation was to save the wallet.dat and delete and restart everything.

My question is, is it possible to delete the 3348075.ldb from the chainstate folder and restart from there? Would that help minimize having to resync the entire blockchain again?

Thank you.

Any guide on on how to set up your own stratum address? I have a bitcoin core running on testnet.

So I was able to set up an account on miningrigrentals. But does anyone by chance have a stratum address:port for me to use to mine tBTC?

Testnet hashrate is over 500TH/s now. I would love to be able to mine on testnet.

I did look into miningrigrental, but I can't set up a new account. They wouldn't send me an email confirmation to confirm my account.

I don't have one of those USB sticks to connect to. Preferably something that will work with the builtin GPU on the Windows that I can mine testnet btc or that I use the pool to connect to maybe nicehash or something.

Ok. Thanks.

Thank you for your response. And of course, it's not rocket science. But if it was easy to find, I would've found it. There's a difference between finding some out of date information that put you in the kinda right direction vs. actually finding the answer to your problem. In reality, there are not that many people in the world who mine mainnet bitcoin. So finding people who mine testnet bitcoin is even smaller than a needle in a haystack. I understand the the discussion is getting off topic. Ending it here. Thanks again for your reponse.

Ok. But how do you get cgminer to work?

Are you mining with an Asic or GPU? I've tried to set up a pool to connect to my fullnode and mine with GPU via cgminer but nothing works. Also, do you have a pool address that can be shared with me? Thanks.

Hey all,

So I've tried to set up my own pool but no luck. So I've decided that maybe if I can use a public testnet for mining btc, then that would be a better option to mine tBTC. Does anyone have the info on a pool that I can use to mine solo tBTC? Thanks.

Do you have a suggestion on which pool I can use to mine testnet btc with a builtin GPU on my Windows computer?

Ah ok.

So I just did a pool test on nice hash and it says pool is incompatible. But it didn't have the option for sha256t and only had option for sha256. However, on mempool, you can clearly see that nicehash is doing testing on testnet. So the pool that I set up doesn't work is what I'm thinking. Anyone has suggestions on to set up a better pool?

Interesting. So it's an auction for testnet btc? How legit is this site?

How do you create a mining pool for testnet btc?

Hey all,

Just curious, is anyone interested in exchanging a full testnet BTC to me? TYIA.

Hey guys. I'm glad I found the right thread. But basically, I've been trying to mine testnet btc using cgminer but no success so far. I'm getting multiple errors. One is Fatal JSON error. The other is need to specify at least one pool server.

I am basically trying to mine with my Windows computer using the built in GPU which is a AMD 550. The cgminer that I am using is 3.7.2. I've seen other version like 4.9.2 but it seems like that version is for asic only.

Could someone post a sample cgminer config for me? Also, I have a testnet full node running. I am supposedly having a P2Pool running also via dockerfile. It shows online. But maybe my config is wrong or something. In any case, can someone post a sample of how I should config my cgminer for a single GPU on a Windows desktop?

Thank you.
