Upgrade Proposal #14: Isthmus L1 Contracts + MT-Cannon
Summary: This poll asks OP holders if they support upgrading L1 contracts to support a hard fork for the Isthmus upgrade (see Upgrade Proposal #15), as well as upgrades to the fault proof VM (Cannon). The Cannon upgrade is designed to remove memory constraints and alters how multi-threading occurs. New operator fee parameters were also introduced.
We strongly recommend voters read the full summary of technical changes here.
Recommendation: Vote For. These changes are prerequisite for Isthmus, and also implement changes expected to improve the fault proof challenge system. The operator fee changes allow for different OP stack chain operators to better customize fees to suit their own provability stack if they so choose, as well as provide flexibility for other ways to utilize the fee. External audits or reviews for this and Upgrade Proposal #15 were completed by Coinbase and Spearbit.
