Odaily Planet Daily News Taiko posted on X that the team is working on upgrading the Taiko-based rollup protocol to the new 1.9.0 version and preparing for Ontake (the first Taiko BCR protocol fork). Ontake can bring the following features to Taiko L2: - Enhanced L2 EIP-1559: The base fee is adjustable in L1, and eventually all relevant parameters will be managed by L1's DAO; - Preliminary support for transaction reconfirmation: Block proposers can deterministically build multiple blocks without submitting old blocks to L1 first; - Batch support: Blocks can be proposed and proved as a batch, opening the door to proof aggregation, which will further reduce Gas costs; - Calldata for contract proposers: Proposers can use Calldata without signature verification. This means that when using Calldata to obtain data availability, the proposer can be either a contract or an EOA.
