Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
Maybe it's mind game, all bot busy for find test , and newly bots maybe also block by ping many times, and in background they play real 66 bit puzzle transaction 
A professional bot definitely does not use mempool.space or similar APIs. It uses its own node, so blocking is only for inexperienced bots that use third-party APIs.You actually need full-node distro. And mempool in local network .You should use a separate machine just for that, and another very powerful machine for the Bot and BSGS/Keyhunt.
So, how many machines you have ?
Five just in my room.
What you talking about? I do it with just my Ryzen 9 3900x with VMs when needed.
I have umbrelOS with node & mempool on seperate machine.
It can be a NUC or any small PC. I don't want to waste RAM at all with VMs on a machine with BSGS server.
