Tezos has activated its Tallinn protocol upgrade, reducing base-layer block times to six seconds.
The upgrade marks the 20th major protocol update since Tezos launched in 2018.
Tezos said the upgrade was implemented without a network fork.
Tallinn allows all network validators, known as bakers, to attest to every block rather than a limited subset.
“This is achieved through the use of BLS cryptographic signatures, which aggregate hundreds of signatures into just one per block,”
Tezos spokespeople said.
Tezos added that the change reduces node load and enables future reductions in block times.
The upgrade also introduced an address indexing mechanism to remove redundant address data.
Tezos said the new indexing system improves storage efficiency by a factor of 100.
The changes are designed to lower latency and speed up transaction finality across the network.
Tezos said the upgrade supports higher throughput as blockchain use cases continue to expand.
The move reflects a broader industry push toward faster settlement and improved base-layer performance.
At the time of reporting, Tezos price was $0.569.
