Bitcoin Unlimited should follow through on their existing support for restricting the transaction version and prepare a working implementation with activation logic for May 2022.


Bitcoin unlimited should:

  1. Publicly announce that they are in favor of restricting the transaction version.
  2. Help set up, or contribute to, a testnet where the restrictions to the transaction version can be verified, before end of August.
  3. Help finalize a specification document based on, or as part of, the CHIP before the end of October.

For example, they could support CHIP-2021-01-Restrict Transaction Versions.md · master · bitcoincash / CHIPs · GitLab


Bitcoin Unlmited benefits from being an active participant in the Bitcoin Cash (BCH) ecosystem, and should be proactive and take part in its development.


There are people in Bitcoin Unlimited who believe that it is getting stagnant, partly due to lack of BUIPs and BUIP engagement. It is undeniably the case that both of these metrics have gone down, but it is not clear what the reason for this result is.


This proposal should fit within existing approved budgets for Bitcoin Unlimited development.
