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 Might 12 publish on X, Yakovenko defined that the proposed meta blockchain wouldn’t function a standalone layer however as an aggregator. It might collect and set up knowledge from numerous chains below a unified transaction ordering system.
The important thing thought is to reference the most recent block headers from every collaborating chain, enabling a shared and deterministic technique for aligning transactions.
He said:
“There ought 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 at the moment accessible DA provide.”
Meta Blockchain
Yakovenko prompt {that a} Meta transaction on Solana may embrace latest blocks from Ethereum and Celestia. This method would scale back uncertainty in transaction sequencing and permit customers to learn from the most cost effective knowledge availability answer.
The Solana co-founder additional emphasised {that a} mounted rule for merging transactions would guarantee consistency throughout the system. This mannequin may cut back reliance on centralized sequencers, which are sometimes seen as single factors of failure in lots of rollup ecosystems.
In his view, a really perfect system would use a protocol that mechanically merges knowledge from all linked chains while not 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, generally known as DA multiplexers, have lengthy existed in idea however are hardly ever applied.
Based on White, such fashions enhance 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 increase overhead, providing restricted advantages in return.
Nevertheless, Yakovenko stays assured that inexpensive and accessible knowledge availability will decrease the price of different on-chain actions. He stated:
“Making knowledge availability low-cost permits for making every thing else low-cost. Bandwidth is the irreducible bottleneck.”
