BUIP094: BCH November upgrade - Re-enable Op Codes
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 re-enabling the following op codes for the scheduled November upgrade (this is a forking change).

Summary of Proposed Changes

Re-enabling op Codes:

  • OP_MUL
  • OP_LSHIFT
  • OP_RSHIFT
  • OP_INVERT

Budget

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.
