v1.2.0

Release Notes v1.2.0 Version 1.2.0 introduces the Helium protocol fork and major enhancements across both MPC and gcEVM, including improved arithmetic circuits, expanded bit-width support, and new debugging capabilities. The update focuses on extending computational expressiveness, improving correctness of arithmetic operations, and providing developers with better visibility into MPC execution.

Changes from v1.1.4

New Fork: Helium

• Introduces updated arithmetic logic across MPC and gcEVM.

• Ensures network-wide alignment for expanded bit-width operations and improved circuit behavior.

MPC – Key Fixes & Improvements

Improved Circuits for Multiplication & Division

1. Updated multiplication and division circuit implementations.

2. Improved correctness and performance based on refined internal circuit structures.

3. Adjusted MPC pricing parameters to reflect updated computation cost.

Trace Debug Support for MPC Operations

1. Introduces developer-facing trace/debug capabilities.

2. Disabled by default, intended for development and testing.

gcEVM – Key Fixes & Improvements

Support for 128-bit and 256-bit Arithmetic

1. Extended gcEVM instruction set and execution logic to handle 128-bit and 256-bit operations natively.

2. Ensures correct integration with updated MPC arithmetic circuits.

3. Enables private smart contracts to execute broader, more complex arithmetic functions.

Fixes

1. Fix for validateCipherText so it wont check nesting level of the caller enabling to use it with Proxy Contracts
