As the blockchain ecosystem continues to evolve, the rollup environment faces serious challenges, especially in terms of sequencer centralization. Taiko, a leader in this field, is pioneering a solution through its ‘Roll Up Foundation’ initiative. According to taiko.mirror.xyz, this innovative approach aims to decentralize the rollup process by enhancing layer 1 (L1) sequence blocks.
Understanding roll-up economics
Rollups are critical to scaling Ethereum as it creates its own economic model. Centralized rollups have their own transaction ordering mechanisms, such as First Come First Serve (FCFS), Priority Gas Auction (PGA), and Timeboost. These mechanisms provide a variety of economic opportunities for rollup operators. However, the centralized sequencer’s monopoly on transaction orders allows it to concentrate power within a single entity by capturing maximum extractable value (MEV) and collecting all priority fees.
‘Based rollup’ perspective
Taiko’s ‘rollup base’ represents a shift towards a more decentralized, permissionless block-building approach. Initially it was thought that MEVs could not be generated, but ‘base rollups’ allow anyone to propose blocks, redistributing MEV opportunities and thus decentralizing the process. In this model, proposers must compete for a priority fee to be included in the L1 block, ensuring that the proposer willing to sacrifice the most profit wins.
Tyco’s unique economic cycle
Taiko operates on a unique economic model that includes a multi-proof structure. Users of Taiko’s Layer 2 (L2) network first pay a fee divided into a tip and a base fee. Tips reward L2 block proposers and base fees support Taiko DAO Treasury. Block proposers must also cover L1 and prover fees. Taiko’s unique fee distribution and block building mechanism aims to encourage decentralization and community participation.
Increased profitability
The profitability of ‘base rollups’ is affected by L1 gas price and L2 gas usage. Taiko’s proponents make money through trading tips by calculating profitability based on gas prices, base fees, and L1 costs. Additionally, the protocol upgrade scheduled for November 15th aims to address current issues with base fee calculations, potentially increasing revenue opportunities for operators and proposers.
Future prospects and additional revenue streams
In the future, Taiko plans to introduce pre-confirmation, which promises to improve user experience and proposer profitability. Pre-confirmation allows bulk offers and immediate transaction confirmation, but slightly reduces activity. Taiko is also exploring additional revenue streams, including selling sequencing rights through an in-protocol marketplace and extracting more value by outsourcing the block construction structure.
Taiko aims to build a path towards a more decentralized and economically secure blockchain ecosystem through innovation through ‘rolling up the foundation’. As the industry continues to explore and experiment with these concepts, the potential for new revenue models and improved decentralization remains promising.
