CHIP Revised: Bigger Script Integers

A new revision to the Bigger Script Integers CHIP has been published. This revision adds a full technical specification and an extensive Rationale section documenting design decisions made in the specification.

The Bigger Script Integers Cash Improvement Proposal (CHIP) expands the integer range allowed in BCH contracts (from 32-bit to 64-bit numbers) and re-enables the multiplication opcode (OP_MUL).

By allowing contracts to efficiently operate on larger numbers, this proposal enables new use cases, improves contract security, and reduces transaction sizes.
