My mistake.

Do you mean BIP141?=

=C2=A0

Your example is an error by BIP141:

=C2=A0

1*4 + 79999*1 =3D 80003 > 80000

=C2=A0

From: bitcoin-dev-bounces@lis= ts.linuxfoundation.org [mailto:bitcoin-dev-bounces@lists.linuxf= oundation.org] On Behalf Of Sergio Demian Lerner via bitcoin-dev=
Sent: Monday, 21 March, 2016 10:51
To: bitcoin-dev <= ;bitcoin-dev@lists.linuxfoundation.org>
Subject: [bitcoin-= dev] BIP147 minor error

<= /u>=C2=A0

The BIP147 reads:=

Sigop cost is defined. The cost of a sigop in t= raditional script is 4, while the cost of a sigop in witness program is 1. =

The new rule is total sigop cost =E2=89=A4 80,0= 00.

But the code implements:

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

=C2=A0... error....

Whic= h is not the same.


For ex= ample:

nSigOps =3D 1
nWitSigOps =3D79999

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

Regards, Sergio.
