Block signature better documentation.
Block signature better documentation.

If the staking tx has a P2PK scriptsig input and a P2PKH scriptpubkey output, there is no way to obtain the public key from any of the scripts to verify the block signature.

Added a good description and an early verification failed return (before it was failing on the pubkey verification, when the problem is actually the staking transaction entirely).
