Title: Generating first block after genesis Post by: crontabaltlinux on March 03, 2019, 05:58:05 AM Hi! I'm currently developing a test altcoin in educational purposes, and can't for some reason generate first pow blocks after generating genesis block. Couple of years ago i successfully made workable fork of fork of dash (or something similar with terribly outdated codebase), but I'm totally unable to reproduce it with modern codebase.
So, to the point. I used PIVX repo, changed chainparams.cpp accordingly: - removed old checkpoints; - generated new keys; - updated ports all over the codebase; - changed pchMessageStart numbers; - updated unixtime; - changed coin name all over the codebase; - generated genesis (and it was correct, i checked it many times); - compiled it; - launched coind; - launched cpuminer, and it failed with the following in log: Code: 2019-02-28 16:55:09 ERROR: CheckProofOfWork() : hash doesn't match nBits I re-generated genesis with code in chainparams.cpp - it was the same as with genesis generator. I tried gen=1 and setgenerate true, and again received the same error, and hashespersec=0 in getmininginfo. I started searching the web, and found a lot of same questions without any answer. For example, this one looks absolutely same - https://bitcoin.stackexchange.com/questions/79767/cannot-mine-genesis-first-block-pivx-fork-clone I tried the kind of solution from this thread - https://bitcointalk.org/index.php?topic=2152157.0;prev_next=next - but without any success too. I assumed that maybe i'm missing something, and tried to do the same with some other PIVX forks. The first one was this - https://github.com/IchibaCoin/ICHIBA - with the same error. The second one was this - https://github.com/cruxcoinsource/CruxCoin - with the same error too. Then i scratched my head, thought deeply, and run diff for all files in /src/ folder of both coins with my testcoin. Files were totally same and differed only where they were different between crux and ichiba. I tried all possible combinations of bools in this part of chainparams.cpp: Code: fMiningRequiresPeers = true; And when fMineBlocksOnDemand was set to true, command setgenerate true returned that wallet keypool is empty, and keypoolrefill command had no effect. What am i doing wrong?..))) Title: Re: Generating first block after genesis Post by: ShllFT on December 23, 2020, 12:28:25 AM Hi!
