A Bitcoin-clone (altcoin) Genesis block generator.

Hello, I'm mycroft!

I'm currently an unemployed software engineer. I also do devops stuff if that matters.

another issue not finding genesis block

Running latest version of master, this took 4 minutes on my machine:

./generate-genesis -nonce 1 -psz "03/May/2024 Bitcoin block" -timestamp 1714777860 -pubkey 000000000000000000000000000000000000000000000000000000000000000000

This command found a solution in a couple minutes:

./generate-genesis -nonce 1 -psz "03/May/2024 000000000000000000001ebd58c244970b3aa9d783bb001011fbe8ea8e98e00e" -timestamp 1714777860 -pubkey 000000000000000000000000000000000000000000000000000000000000000000

But this one ran for over half an hour without finding anything and exhausting the nonce space:

./generate-genesis -nonce 1 -psz "03/May/2024 Bitcoin block 000000000000000000001ebd58c244970b3aa9d783bb001011fbe8ea8e98e00e" -timestamp 1714777860 -pubkey 000000000000000000000000000000000000000000000000000000000000000000
nonce was reset. Timestamp is now 1714777861

psz length check too high?

Just a heads up in case you want to look into it.

It seems like the length check for psz is way too high. The tool allows me to attempt generating a block with a psz that is hundreds of characters. If I try that, it simply never finds a block.

Or maybe it isn't specifically the max psz length, but something related to longer pszs. All I know is that when I try generating a genesis block with a psz > 64 chars, I never succeed in minting a block even after having the script run for hours.
