This is my endorsements for the Bitcoin Cash CHIPs targeted for activation on May 15th 2026.
TLDR; I fully support the activation of the four proposed CHIPs by Jason Dreyzehner.
Bitwise operators
Reactivation of old op codes. This is a no-brainier. Fully endorse.
Loops
One of the exciting building blocks for Bitcoin Cash Script once the VM Limits CHIP was deployed in 2024. Fully endorse.
Pay2Script
At first I was a bit skeptical regarding UTXO set growth, both regarding locking scripts that previously was implemented as P2SH(32) might now be significantly bigger and the increase of CashToken NFT commitments from 40 bytes to 128 bytes. Upon further review I think this change is net good. Fully endorse.
One of the first use-cases that comes to my mind is that indexers can find certain contracts by just scanning the UTXO set instead of scanning spent transactions to find a mapping between contracts and redeem script hashes.
Functions
This is a very exciting CHIP that will, together with Loops, unlock a lot of power to contract authors. Fully endorse.
Even though I find the predecessor CHIP (OP_EVAL) cleaner from a more academic point of view, where the stack is the state of the VM, I agree with the rationale of using a function table.
