Tezos activated its twentieth protocol upgrade, Tallinn, following an on-chain governance process with participation from all bakers and the community. The update was developed by Nomadic Labs, Trilitech, and Functori.
Tallinn reduces Layer-1 block time to 6 seconds, accelerating transaction finality. The EVM-compatible Layer-2, Etherlink, confirms operations in under 50 milliseconds, now backed by Layer-1 finality in 12 seconds. All bakers can attest to each block using BLS signatures, which aggregate hundreds of signatures into a single one, reducing node load and enabling future block time reductions.
The upgrade introduces an Address Indexing Registry that improves storage efficiency by up to 100x for Michelson-based apps, eliminating redundant address data and lowering costs. The network maintains full decentralization and optimizes its infrastructure for enterprise applications, large NFT ledgers, and other setups with high storage demand.
Tallinn was activated without forks or interruptions, delivering improvements in speed, security, and efficiency across the entire Tezos blockchain.
