EIP-3607: Reject transactions from senders with deployed code

Browse Source 
Any transaction where tx.sender has a CODEHASH != EMPTYCODEHASH MUST
be rejected as invalid, where EMPTYCODEHASH =
0xc5d2460186f7233c927e7db2dcc703c0e500b653ca82273b7bfad8045d85a470.
The invalid transaction MUST be rejected by the client and not be included
in a block. A block containing such a transaction MUST be considered invalid.
