📝 Original message:Do you mean BIP141?



Your example is an error by BIP141:



1*4 + 79999*1 = 80003 > 80000

Subject: [bitcoin-dev] BIP147 minor error



The BIP147 reads:

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.

The new rule is total sigop cost ≤ 80,000.

But the code implements:

if (nSigOps + (nWitSigOps + 3) / 4 > MAX_BLOCK_SIGOPS)

... error....

Which is not the same.


For example:

nSigOps = 1
nWitSigOps =79999

Is not an error by BIP definition but it's an error by the implemented code.

Regards, Sergio.
