On September 13, Taiko posted on X that the team is working on upgrading the Taiko-based rollup protocol to a new 1.9.0 version and preparing for Ontake (the first TaikoBCR protocol fork). Ontake brings the following features to Taiko L2: - Enhanced L2EIP-1559: The base fee is adjustable at L1, and eventually all relevant parameters will be managed by the DAO at L1. - Initial support for transaction reconfirmation: block proponents can confidently build multiple blocks without first submitting the old block to L1. Batch support: Blocks can be proposed and proven as a batch, opening the door to proof aggregation, which will further reduce gas costs. - Calldata for contract proponents: Proponents can use Calldata without signature verification. This means that when using Calldata to obtain data availability, the proponent can be either a contract or an EOA.
