Tezos' Tallinn Upgrade Reduces Block Time to Six Seconds

The Tezos blockchain has successfully implemented its 20th protocol upgrade, named Tallinn, which brings significant enhancements to the network.

One of the most notable changes is the reduction of block time from eight seconds to six seconds, enabling Level 1 finality in just 12 seconds. This improvement aims to provide lower latency for transactions while ensuring that all bakers can validate each block, enhancing security and predictability in rewards.

Developed by a team from Nomadic Labs, Trilitech, and Functori, the Tallinn upgrade also introduces the Address Indexing Registry. This feature can vastly improve storage efficiency—potentially up to 100 times—by minimizing redundant data in smart contracts, which is particularly beneficial for enterprise applications within the Michelson execution environment.

The effectiveness of the bakers to confirm blocks will activate once over half of the validators switch to the tz4 address format, leveraging the BLS signature scheme for improved network functionality.

Despite these advancements, the native token XTZ remains relatively stable at around $0.58, a stark contrast to its peak of $9.12 in October 2021. As of now, the total value locked in the Tezos protocol is $35.2 million, primarily driven by the Youves synthetic asset platform and the Sirius decentralized exchange.

Tezos co-founder Arthur Breitman previously highlighted the need for a fundamental basis in cryptocurrencies, pointing to this as a potential risk moving forward.
