The design of Bitcoin allows computers to compute a hash with 2 iterations of the SHA256 compression function instead of 3 on all but 1 out of every 2^32 attempts. When Satoshi chose SHA256d for Bitcoin, did he intend to allow this?

This defines "midstate" as the "precomputed hash state after hashing the first half of the data." I've heard "midstate" used in the context of speeding up hashing. How does using a midstate speed up hashing?

I read somewhere that a node is banned for 24 hours. However I found the Misbehaving() function which makes state->fShouldBan = true;. But I could not find any other function that makes state->fShouldBan = false;. It seems that banning is…
