Sigops per block is currently limited to 20,000. We change this restriction as follows: -''Sigop cost'' is defined. The cost of a sigop in traditional script is 4, while the cost of a sigop in witness program is 1. +Sigops in the current pubkey script, signature script, and P2SH check script are counted at 4 times their previous value. +The sigop limit is likewise quadrupled to ≤ 80,000. -The new rule is total ''sigop cost'' ≤ 80,000. +In addition, opcodes within the witness program are counted identical to as previously within the P2SH check script. +That is, CHECKSIG is counted as only 1 sigop in a witness program, despite P2SH check script's CHECKSIG becoming 4 sigops with the forementioned change. == Examples == |
