Evaluation Process

MidChains evaluates:

  • What is changing?

  • Analysing the impact of those changes.

  

What is Changing?

  •  Consensus changes

    • CHIP-2021-03: Bigger Script Integers - This proposal expands the integer range allowed in BCH contracts (from 32-bit to 64-bit numbers) and re-enables the multiplication opcode (OP_MUL).

    • CHIP-2021-02: Native Introspection Opcodes - This proposal adds a set of new virtual machine (VM) operations which enable BCH contracts to efficiently access details about the current transaction like output values, recipients, and more – without increasing transaction validation costs.

 

Upgrade Preparation

For Bitcoin Cash users, this upgrade requires no preparation; payments can safely be made and accepted throughout activation. Existing wallet software will continue to function without upgrades.

Miners, exchanges and other node operators are advised to upgrade node software before May 15, 2022 to avoid service disruptions. The upgrade requires no downtime, and operations can proceed normally.
