Nice. The blockchain looks stable now, lets see where it goes.
As it turns out, not really stable.
It just stops yesterday for no reason after block 12299.
Node restarting does not help.
Also changing chain id made nodes ignore old blocks.
As for the mining pools - I think you must recompile new version with the new chain id.
I would think that you can't just change the ChainID in-flight without further changes to the code.
Didn't check your source, but on Doge it would need quite a few changes to make that happen when the chain already has blocks with the old ChainID.
