Solana co-founder Anatoly Yakovenko has proposed making a “meta blockchain” designed to decrease knowledge availability (DA) prices whereas boosting interoperability throughout a number of blockchain networks.
In a Could 12 submit on X, Yakovenko defined that the proposed meta blockchain wouldn’t function a standalone layer however as an aggregator. It could collect and set up knowledge from numerous chains beneath a unified transaction ordering system.
The important thing thought is to reference the newest block headers from every collaborating chain, enabling a shared and deterministic technique for aligning transactions.
He acknowledged:
“There needs to be a meta blockchain. Submit knowledge anyplace, Ethereum, celestia, Solana, and use a particular rule to merge knowledge from all of the chains right into a single ordering. This might really permit the meta chain to make use of least expensive presently accessible DA provide.”
Meta Blockchain
Yakovenko prompt {that a} Meta transaction on Solana might embody current blocks from Ethereum and Celestia. This method would cut back uncertainty in transaction sequencing and permit customers to learn from the most affordable knowledge availability answer.
The Solana co-founder additional emphasised {that a} mounted rule for merging transactions would guarantee consistency throughout the system. This mannequin might cut back reliance on centralized sequencers, which are sometimes seen as single factors of failure in lots of rollup ecosystems.
In his view, an excellent system would use a protocol that routinely merges knowledge from all related 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 thought, noting that related proposals, referred to as DA multiplexers, have lengthy existed in idea however are not often applied.
In response to White, such fashions enhance operational complexity as a result of rollups must 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 knowledge availability will decrease the price of different on-chain actions. He stated:
“Making knowledge availability low-cost permits for making all the pieces else low-cost. Bandwidth is the irreducible bottleneck.”
