Mina ends the upgrade mechanism test plan to ensure seamless transition of Berkeley upgrades, and will then upgrade Mina Devnet

On March 6th, O(1)Labs, the Mina development team, announced that they have completed the Upgrade Mechanism Testing (UMT) program with MinaFoundation to ensure a seamless transition to the Berkeley upgrade. The focus of the UMT program was to verify end-to-end and dry-running upgrade mechanisms and tools, which are a part of the Berkeley upgrade. O(1)Labs stated that they will upgrade Mina Devnet later.

The three main features of the Mina Berkeley upgrade include the use of o1js (previously known as SnarkyJS, a TypeScript library for writing zkApps) for ZK programming; the Mina proof system Kimchi enhances security and efficiency, helping to create recursive ZK proofs; and the cancellation of excess rewards (temporary incentives for increasing staking in the early stages of the mainnet).
