Solana co-founder Anatoly Yakovenko has proposed making a “meta blockchain” designed to decrease information availability (DA) prices whereas boosting interoperability throughout a number of blockchain networks.
In a Might 12 put up on X, Yakovenko defined that the proposed meta blockchain wouldn’t function a standalone layer however as an aggregator. It might collect and arrange information from varied chains underneath a unified transaction ordering system.
The important thing concept is to reference the newest block headers from every collaborating chain, enabling a shared and deterministic methodology for aligning transactions.
He said:
“There needs to be a meta blockchain. Submit information anyplace, Ethereum, celestia, Solana, and use a selected rule to merge information from all of the chains right into a single ordering. This could really enable the meta chain to make use of most cost-effective at present obtainable DA provide.”
Meta Blockchain
Yakovenko urged {that a} Meta transaction on Solana might embrace latest blocks from Ethereum and Celestia. This strategy would cut back uncertainty in transaction sequencing and permit customers to profit from the most cost effective information availability answer.
The Solana co-founder additional emphasised {that a} fastened rule for merging transactions would guarantee consistency throughout the system. This mannequin might scale back reliance on centralized sequencers, which are sometimes seen as single factors of failure in lots of rollup ecosystems.
In his view, a super system would use a protocol that mechanically merges information from all linked chains without having an exterior coordinator.
He stated:
“A lame model of this depends on an exterior sequencer. I believe the cooler model is only a merge rule that reads all of the chains. So customers can ship txs anyplace.”
Feasibility problem
Whereas the idea has sparked curiosity, not everyone seems to be satisfied of its practicality.
Celestia COO Nick White pushed again on the concept, noting that related proposals, often known as DA multiplexers, have lengthy existed in idea however are hardly ever applied.
In accordance with White, such fashions improve operational complexity as a result of rollups have to run nodes for every DA layer. Moreover, managing the fork-choice guidelines throughout a number of chains would considerably elevate overhead, providing restricted advantages in return.
Nonetheless, Yakovenko stays assured that reasonably priced and accessible information availability will decrease the price of different on-chain actions. He stated:
“Making information availability low cost permits for making every thing else low cost. Bandwidth is the irreducible bottleneck.”
