Solana co-founder Anatoly Yakovenko proposed making a “metablockchain” designed to cut back information availability (DA) prices whereas growing interoperability between a number of blockchain networks.

In a Could twelfth submit on X, Yakovenko defined that the proposed metablockchain is not going to act as a standalone layer, however as an aggregator. Accumulate and set up information from totally different chains beneath a unified transaction ordering system.

The important thing thought is to check with the most recent block headers from every taking part chain, permitting for a shared, deterministic manner of coordinating transactions.

He stated:

“We’d like a metablockchain. We submit information in all places and merge information from all chains right into a single order utilizing Ethereum, Celestia, Solana and particular guidelines.

Metablock Chain

Yakovenko instructed that metatransactions in Solana might embrace current blocks from Ethereum and Celestia. This strategy reduces transaction sequence uncertainty and allows customers to learn from the most affordable information availability options.

The Solana co-founder additional emphasised that fastened guidelines for merging transactions guarantee consistency throughout the system. This mannequin can cut back the dependency on centralized sequencers. That is typically seen as a single impediment in lots of roll-up ecosystems.

In his view, the best system makes use of a protocol that robotically merges information from all related chains with out the necessity for an exterior coordinator.

He stated:

“The lame model of this depends on exterior sequencers. I feel the cooler model is a merge rule that reads all chains. Customers can ship TXS anyplace.”

The problem of feasibility

This idea has sparked curiosity, however not everybody is certain of its practicality.

Celestia COO Nick White pushed the thought again by stating {that a} related proposal generally known as Da Multiplexers has lengthy been current within the concept however isn’t applied.

In keeping with White, such fashions improve operational complexity, because the rollup requires nodes in every DA layer to be run. Moreover, managing fork choice guidelines throughout a number of chains will lead to a big overhead rise and a restricted profit in return.

Nevertheless, Yakovenko believes that the provision of reasonably priced and accessible information will cut back the prices of different chain actions. He stated:

“By decreasing information availability, the whole lot else may be cheaper. Bandwidth is an irreducible bottleneck.”
