cross-posted from the 'new new 9.2' catcoin thread:
It's been a fun day of node attacks, fake blocks, and amateurish DoS attempts. Yet CAT blocks just keep flowing towards 46331. Life is Good!
It's best, as a developer, to generally assume poor configuration or outdated clients rather than assume you are under attack.
This is *probably* the result of 9.1.1 nodes that got restarted and are trying to download the blockchain. I'm seeing the same problem, so it seems the best solution would be that both forks release new versions.
I can make the problem go away (for me) if I change the PCHmessage after some block (like maybe 46331), but you will still have problems with old 9.1.1 clients (that for all we know are still mining). If you can also change the 'new 9.1.1' catcoin thread to point to **new** binaries you'd also have a better chance at fixing this problem.
