Tezos completes Tallinn upgrade, cutting app storage costs by up to 100x

The Tezos blockchain successfully activated its 20th protocol upgrade, Tallinn, through a decentralized on-chain governance process. Developed by Nomadic Labs, Trilitech, and Functori, this upgrade introduces significant performance enhancements, including reducing layer 1 block times to six seconds and strengthening security via universal validator attestations using BLS signatures. A key feature is the new Address Indexing Registry, which can reduce application storage requirements by up to 100 times, significantly lowering costs and increasing throughput for enterprise applications and large NFT ledgers. Yann Régis-Gianas of Nomadic Labs highlighted that this decentralized adaptation proves Tezos' reliability. Furthermore, Tallinn enhances Tezos' role as a settlement layer for Etherlink, its EVM-compatible L2, by providing L1 finality in just two blocks (12 seconds).
