Structured testing pushes Mesa closer to mainnet launch. * Guido Battigelli * Published: April 10, 2026 * 3:46 pm * Updated: April 10, 2026 * 3:46 pm Home > CryptoNews > structured testing pushes Mesa closer to mainnet launch. Table of Contents * Mesa Testnet completed 9 upgrade rehearsals and optimizations that reduced packaging time from 2 hours to 22 minutes. * The o1Labs team launched o1js 3.0 in preview, offering full compatibility with Mesa and zkApp migrations from Berkeley. * The next stage is Mesa Trail, which will exactly replicate the mainnet upgrade process and will include the Trailblazers incentive program. The engineering team at o1Labs published a detailed update on the status of Mesa, the next major protocol upgrade for the Mina network. The report documents the work carried out over the past month on the testnet, launched in November 2025 as an intentionally unstable pre-production environment, designed to detect issues early and lay the groundwork for a safe migration to mainnet. Among the most significant advances, the team completed nine upgrade rehearsals across different modes, configurations and architectures. Rehearsals 7 and 9 were corporate-scale, involving participants from multiple time zones and varying levels of experience to simulate a realistic upgrade scenario. During these tests, a glibc dependency issue was identified and resolved, and a bug preventing nodes from starting correctly under certain conditions was fixed. Mesa accelerates its infrastructure speed. One of the most notable achievements of the period was the optimization of the packaging pipeline, which reduced package generation time from two hours to just 22 minutes. The team also developed a real-time monitoring tool that allows users to visualize what percentage of active stake has migrated to the new version, and launched a dedicated explorer with a full history of blocks and transactions for all networks associated with Mesa. At the protocol level, the OCaml workstream completed the automatic upgrade mode for the hard fork, a substantial improvement over the manual process used in previous versions. The average block time on the Testnet was also corrected, and a persistent memory leak in the Mina daemon linked to the libp2p auxiliary code was resolved. The road to Trail. On the application development front, the team launched a preview version of o1js 3.0, which provides complete tooling for developers. The end-to-end migration pipeline was also completed to upgrade zkApps from Berkeley to Mesa, with successful tests of the upgrade mechanism carried out during recent rehearsals. The next stage of the process is Trail, which will start from a state similar to Berkeley's and execute a full upgrade replicating exactly what will happen on mainnet. Prior to its launch, a final rehearsal will be conducted after the code freeze. Simultaneously, the Trailblazers program will be launched, an initiative offering incentives for experienced node operators, selected to represent diverse geographies, hardware configurations and deployment environments.

The upgrade establishes Mina as the first zero knowledge (ZK) blockchain with native ZK programmability, enabling developers to build with a powerful framework for leveraging ZK features for scalability, privacy, and verification in their applicationsGENEVA, June 7, 2024 /PRNewswire/ -- Mina Protocol , the zero knowledge (ZK) blockchain for proving anything, has completed a major network upgrade process bringing enhanced ZK programmability to its mainnet. The upgrade enables zkApps to be built and deployed on the Mina mainnet, setting the stage for the development of new zero knowledge-powered use cases and equipping builders with a powerful and easy-to-use ZK developer toolkit.In development since 2021, the long-anticipated upgrade moves smart contract execution off-chain, and leaves verification on-chain, solving many of the most common blockchain infrastructure challenges, such as data constraints, scalability issues, and high gas costs. This paradigm shift makes it easier for developers to build with zero knowledge and create zkApps, granting new levels of control and ownership for users over their data.zkApps can enable and scale new use cases for voting, healthcare, digital identity, gaming, and much more. Examples of projects already building in the Mina ecosystem include PunkPoll , a censorship-resistant survey and voting platform, bioSNARKs , a stack for biotech data, Hakata , a solution offering "compliant privacy" for Web2 and Web3 companies, and Paima Studios , an engine for on-chain gaming. Unlike many other dApp platforms that use new programming languages, zkApps use o1js , a TypeScript-based library already understood by a wide pool of TypeScript developers who are now empowered to build with ZK.Kurt Hemecker , CEO of Mina Foundation , an organization serving the Mina Protocol and its ecosystem, said, "This upgrade not only marks a major milestone for the Mina community but is a significant breakthrough for the industry as a whole. The killer use cases for blockchain – DeFi, on-chain gaming, digital identity, blockchain interoperability, voting, secure supply chains, and compliance – all require zero knowledge proofs as a foundation to innovate and scale
