This proposal outlines the implementation of MT-Cannon which removes memory constraints for the fault proof program, and introduces the Operator Fee which is the first phase of addressing the challenges in accurately pricing user fees when chains employ ZK proving, alt-DA, and custom gas tokens.

This proposal:

• upgrades Cannon, the fault proof VM to a new version that supports the MIPS-64 instruction set and supports running multi-threaded programs, removing memory constraints for the fault proof program (MT-Cannon), and
• introduces the first phase of a mechanism addressing challenges in accurately pricing user fees when chains employ ZK proving, alt-DA, and custom gas tokens (Operator Fee).
