BUIP095: BCH November upgrade - CHECKDATASIG & CHECKDATASIGVERIFY
Proposer: Andrew Clifford (@solex)
Submitted on: 2018-08-14
Status: passed

Motivation

Bitcoin Cash is advancing through decentralized development. Perhaps
this was easier early-on, but now the dust has settled from the fork and
a year has passed, there are many different voices pushing and pulling
development priorities. The upcoming 15 November 2018 general upgrade is
a major event, hence it would help if Bitcoin Unlimited, as an
organization, had an official position on the major elements of the
upgrade. This position is determined by the membership.

Objective

The purpose of the BUIP is to determine whether the BU membership
supports creating the following new op codes in the scheduled November
upgrade (this is a forking change).

Summary of Proposed Changes

Create new op codes:

OP_CHECKDATASIG and OP_CHECKDATASIGVERIFY

N/A

Impact

BU does not desire unintended forks in the BCH blockchain, so the BU
client will remain compatible with the final specification of the
November upgrade.
