Error on handling HoneyBadger message. #64

Open SurfingNerd opened 2 years ago

SurfingNerd commented 2 years ago

we do have a lot of HoneyBadger message that can not be handled.

One known origin for this message is a missmatch between the HBBFT Signing key and the Transaction Signing Key as we have in the protocol here: https://github.com/DMDcoin/openethereum-3.x/issues/62 IN this case block production did not work anymore, because 1 out of 2 Nodes missed out, so we did not get the 2/3 majority.

But there might be other cases that need get attention.

it happens if a node drops out of current honey badger set, on the next block the node is not known to the honey badger engine, and cannot handle messages from the past. This is very common
