Tezos Tallinn Upgrade Live — Cuts Block Time to 6 Seconds
The Tezos network went live with the Tallinn upgrade on Jan 25, 2026, shaving average block time down to roughly 6 seconds. Tallinn is the platform's 20th major protocol update since launch in 2018 and was implemented without requiring a fork, demonstrating smoother on-chain governance and lower operational disruption for validators and users.
Faster blocks are expected to improve transaction throughput and responsiveness for dApps and DeFi protocols built on Tezos, while the forkless activation reduces fragmentation risk and coordination overhead. The upgrade could boost XTZ utility in payments and time-sensitive applications, though real-world performance gains will depend on adoption by node operators and developers integrating the new timing parameters.
