Tezos' Tallinn Update Reduces Block Times to 6 Seconds

Tezos's Tallinn Update Shortens Block Times

The layer 1 proof-of-stake blockchain network Tezos deployed its latest protocol update, Tallinn, on January 26, 2026. With this significant update, block times have been reduced to 6 seconds. This change has significantly increased the overall efficiency and transaction speed of the network.

Benefits of the Update

According to Tezos's announcement, the Tallinn protocol not only shortens block times but also reduces storage costs. The new update has accelerated the finality times of the network, providing users with the opportunity to make transactions more quickly.

Bakers and Validation Processes

The Tallinn update allows the network validators, known as "bakers," to validate each block. In previous versions, only a subset was validating blocks. This new system includes the use of BLS cryptographic signatures, which combine hundreds of signatures into a single signature per block. This way, the load on nodes is alleviated, and block times can be shortened further.

Address Indexing Mechanism

The update introduces an indexing mechanism that removes "unnecessary" address data. Tezos spokespersons indicate that this mechanism increases storage efficiency by 100 times. This change significantly reduces the storage needs of applications running on Tezos.

Transformation in Speed and Efficiency

This update from Tezos demonstrates the efforts to create a blockchain network that can handle more transactions per second and adapt to increasing use cases. Unlike first-generation blockchains, Tezos has undergone a significant transformation in speed and efficiency through its updates.

Conclusion

Tezos's Tallinn update not only improves user experience by reducing block times to 6 seconds but also lowers storage needs. The innovations achieved in blockchain technology serve as an example for other networks in the industry.
