The Tallinn protocol upgrade marks Tezos’ 20th major update since launching in 2018, and was implemented without a network fork.
Tezos, a layer-1 proof-of-stake blockchain network, implemented its latest protocol upgrade, Tallinn, on Saturday, which reduced block times on the base layer to 6 seconds.
The latest upgrade is the 20th update to the protocol, which reduces block times, slashes storage costs and reduces latency, resulting in faster network finality times, according to an announcement from Tezos.
Tallinn also allows all network validators, known as “bakers”, to attest to every single block, rather than a subset of validators attesting to blocks, which is how validators verified blocks in previous versions of the protocol, Spokespeople for Tezos explained:
