Ethereum Layer 2 Taiko has enabled permissionless sequencing and proving following its mainnet rollout and token launch — claiming to become the first rollup to do so.

Permissionless sequencing allows anyone to sequence Taiko blocks in a decentralized way, the team said, in contrast to other Ethereum rollups that currently rely on centralized sequencers to order their blocks, introducing various risks.

In a process known as based sequencing, block ordering for Taiko is carried out by Ethereum mainnet validators and block builders, the project says.

“This type of block ordering, created by Ethereum researcher Justin Drake, inherits liveness and security guarantees from Ethereum base layer,” Taiko said.

In terms of permissionless proving, participants can now spin up a Taiko node and …
