What happens to that block? E.g, in Bitcoin, when a node receives an invalid block, it absolutely refuses to add it to the blockchain. I realize that PoS stake blockchains, like Flow, operate differently.
If a node tries to forge an invalid block signature, or do anything byzantine, the other nodes will detect the behavior, not include it, and the node’s stake will be slashed to punish them. Does that make sense? Do you need more detail than that? I could find someone to elaborate
