The Tezos blockchain has reached a new, significant milestone with the activation of its twentieth protocol evolution, named Tallinn.
The update, developed by Nomadic Labs, Trilitech, and Functori, was approved and implemented through an on-chain governance process that actively involved both the bakers (network validators) and the community.
This achievement further solidifies Tezos’ reputation as one of the most reliable blockchains, capable of quickly adapting to market demands without ever disrupting network operations.
According to Yann Régis-Gianas, Head of Engineering at Nomadic Labs, “adapting to market demands 20 times in 7 years, without ever experiencing interruptions and in a completely decentralized manner, is irrefutable proof of the reliability and long-term vision of Tezos.”
Dramatic Reduction in Block Times: Just 6 Seconds
One of the most revolutionary aspects of the Tallinn upgrade is the reduction of Layer-1 block time to just 6 seconds. This means that transactions are confirmed much more quickly, reducing latency and accelerating finality on the network’s censorship-resistant settlement layer.
This innovation integrates seamlessly with Etherlink, the EVM-compatible Layer-2 solution of Tezos, which already confirms transactions in less than 50 milliseconds. Now, thanks to the Layer-1 finality achieved in two blocks (i.e., 12 seconds), the user experience and transaction security are further enhanced.
Enhanced Security and More Predictable Rewards
Another innovation introduced by Tallinn concerns the block validation mechanism. From now on, all bakers can attest to every block, no longer just a selected subset. This change enhances network security and makes staking rewards more predictable for participants.
The key to this innovation lies in the adoption of BLS cryptographic signatures, which allow the aggregation of hundreds of signatures into one per block. This lightens the load on network nodes, paving the way for potential further reductions in block times in the future.
Application Storage Up to 100 Times More Efficient
The Tallinn update also introduces a feature called Address Indexing Registry, which promises to revolutionize storage management for applications using the Michelson runtime.
By eliminating redundant address data, apps adopting this functionality can benefit from up to 100-fold reduction in storage costs and increased throughput capacity.
Yann Régis-Gianas emphasized how this innovation was developed by listening to the needs of builders on Tezos: “Our development team is excited to deliver such drastic improvements for enterprise-level applications, large NFT ledgers, and other solutions that manage many addresses.”
Seven Years of Continuous Evolution Without Forks
Since its launch in 2018, Tezos has stood out for its ability to evolve without ever resorting to forks, thanks to an on-chain governance system that constantly involves the community and validators. Each protocol update has introduced new features designed to enhance the experience for both users and developers.
With Tallinn, Tezos takes another step forward towards a faster, more secure blockchain optimized for enterprise use, without ever compromising decentralization.
This upgrade is yet another demonstration of the network’s ability to quickly adapt to user needs and ensure longevity through continuous innovation and optimization.
Tezos: A Blockchain Designed for the Future
Tezos is an open-source, energy-efficient blockchain designed to support institutions, developers, and businesses in managing and transferring value in a digital environment. Thanks to its modular and scalable design, Tezos is perfectly suited for the deployment of next-generation decentralized applications.
Among the first projects to implement Proof of Stake on a global scale, Tezos has earned the respect of the international community for its robust governance, ability to upgrade over time, and advanced smart contract functionalities.
Conclusions: a Constantly Growing Ecosystem
The Tallinn upgrade marks a new era for Tezos, reaffirming its status as one of the most dynamic and innovative blockchains on the global scene. The reduction in block time, enhanced security, reward predictability, and storage efficiency are just some of the advantages that will make Tezos even more attractive to developers, businesses, and end users.
