Tezos' Tallinn upgrade reduces block generation time to six seconds, significantly improving security and storage efficiency.
The Tezos (XTZ) blockchain has successfully implemented its 20th protocol upgrade, "Tallinn." This update shortens the block generation cycle to six seconds, expands the scope of validator participation, and reduces application storage costs by up to 100x.
The Tezos Foundation announced on the 26th (local time) that the Tallinn upgrade had officially been implemented on the mainnet after passing an on-chain governance vote. The upgrade, jointly developed by developers Nomadic Labs, Trillitech, and Punktory, marks the 20th protocol evolution since the network launched in 2018.
Block generation time reduced to 6 seconds… Final confirmation time also accelerated to 12 seconds.
The most notable change in the Tallinn upgrade is the shortened block generation interval. New blocks are now generated every six seconds, a shorter time than before, and transaction finality has been shortened to approximately 12 seconds (within two blocks). This move is interpreted as a move to increase dApp responsiveness and enhance the user experience, while also strengthening Tezos' position as a high-performance decentralized payment layer.
This upgrade also enhances compatibility with Tezos' Ethereum Virtual Machine (EVM)-compatible Layer 2 solution, Etherlink. Etherlink processes Layer 1-based final consensus within approximately 50 milliseconds, providing a significantly faster transaction experience.
All validators sign blocks… Security and reward predictability increase.
The validator structure has also been significantly improved. Previously, only a select number of validators could sign (certify) blocks, but with the implementation of Tallinn, all validators on the network can now sign all blocks. This is based on the Boneh–Lynn–Shacham (BLS) cryptographic signature technique. This feature allows multiple individual signatures to be combined into a single aggregate signature, contributing to increased security and reduced network load.
This restructuring of the validator structure is expected to have a positive impact on participants, as it will strengthen the overall security of the system and make staking rewards more predictable.
Introducing an address indexing registry…smart contract storage costs reduced by a factor of 100.
The Tallinn upgrade also focuses on improving storage efficiency for developers. Applications written in Tezos' native smart contract language, Michelson, will be introduced with the Address Indexing Registry. This is designed to significantly reduce storage space by eliminating duplicate address data.
The Tezos Foundation explains that this will improve storage efficiency by up to 100 times, which is expected to reduce costs and make it easier to develop applications that process large amounts of data.
On-chain governance highlights its strengths, continuing the success of non-disruptive network upgrades.
Tezos is a leading on-chain governance blockchain that has repeatedly implemented risk-free network upgrades. Tallinn was also implemented smoothly, without network outages or hard forks.
The foundation emphasized that “Tallinn is the cornerstone for a faster, more secure, and more cost-effective Tezos,” and that “it will immediately benefit a diverse user base, including dApp developers, NFT platforms, and enterprise blockchain solution providers.”
Tezos is an open-source blockchain platform that is attracting attention as an infrastructure for enterprises, institutions, and developers, boasting energy efficiency, protocol stability, and a flexible smart contract environment. With Tallinn, the network's competitiveness is expected to further increase with improvements in speed, security, and storage performance.
💡 "Blockchain that delivers both performance and security… Your analytical skills need to be upgraded, too."
As seen in the article about Tezos' "Tallinn" upgrade, complex technical and economic structures lie behind key variables like block generation speed, security, and storage efficiency.
