November 30, 2025 – Mina Protocol Mesa Testnet launches as the pre-flight phase for faster slot times and expanded zkApp limits, inviting community testing before the upcoming hard fork.
The Mina Protocol Mesa Testnet marks the beginning of public testing for the network’s next major upgrade. Announced on November 30, 2025, Mesa allows builders, validators, and contributors to experiment with new performance improvements before the hard fork.
The goal is to finalize the upgrade through iterative community feedback, ensuring stability and preparedness across the ecosystem.
Mesa introduces multiple upgrades designed to enhance Mina’s zero-knowledge infrastructure. Faster slot times aim to increase throughput across the chain, while higher limits for zkApp account updates, events, actions, and state sizes provide developers with greater flexibility.
These adjustments expand the design space for next-generation zero-knowledge applications that require more complex interactions.
Mina Protocol will publish a full hard-fork timeline after collecting data on Mesa’s performance and stability. The testnet includes several checkpoint phases, each designed to validate specific improvements before progressing to broader stages.
Contributors are encouraged to stress test the network, report issues, and help refine the upgrade before its mainnet deployment.
The Mesa Testnet represents a significant step toward improving Mina’s scalability and developer experience. By enabling more powerful zkApps and quicker confirmations, the update aims to increase adoption across Web3 sectors that require lightweight but secure zero-knowledge infrastructure.
Successful testnet results could strengthen Mina’s positioning as a core ZK-native blockchain heading into 2026.
