Bitcoin Cash (BCH) developers and community members have been actively voicing their support for two Cash Improvement Proposals (CHIPs) ahead of a November 15 lock-in deadline. The “VM Limits” (Virtual Machine Limits) and “BigInts” (Big Integers) CHIPs seek to streamline smart contract capabilities onchain for the Bitcoin Cash network and enable more possibilities for developers to build on the protocol.
VM Limits and BigInts — Two proposed upgrades for Bitcoin Cash
First, it may be necessary to point out that Bitcoin Cash already has functioning UTXO (unspent transaction output)-based smart contract capabilities, allowing for smart contracts to be executed on-chain. This was made possible via the CashTokens CHIP back in 2023.
The two CHIPs gaining support for the 2025 network upgrade are:
CHIP-2021-05 VM Limits: Targeted Virtual Machine Limits
CHIP-2024-07 BigInt: High-Precision Arithmetic for Bitcoin Cash
These two dovetailing proposals aim to make smart contracts on BCH much more efficient, and to render “previously-theoretical use cases immediately practical.” So what are the use cases?
2025 BCH upgrade proposals see massive community support, with some caveats
General Protocols initially had some reservations about one of the 2025 CHIPs, as it was a relative latecomer to the table compared to previous proposals.
