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 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 manage knowledge from varied chains beneath a unified transaction ordering system.
The important thing concept is to reference the most recent block headers from every collaborating chain, enabling a shared and deterministic technique for aligning transactions.
He acknowledged:
“There must be a meta blockchain. Put up knowledge wherever, Ethereum, celestia, Solana, and use a selected rule to merge knowledge from all of the chains right into a single ordering. This is able to really permit the meta chain to make use of most cost-effective at present accessible DA provide.”
Meta Blockchain
Yakovenko steered {that a} Meta transaction on Solana may embrace current blocks from Ethereum and Celestia. This method would cut 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} fastened rule for merging transactions would guarantee consistency throughout the system. This mannequin may cut back reliance on centralized sequencers, which are sometimes considered 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 while not having an exterior coordinator.
He mentioned:
“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 wherever.”
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 comparable proposals, often known as DA multiplexers, have lengthy existed in idea however are not often carried out.
Based on White, such fashions improve 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 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 mentioned:
“Making knowledge availability low-cost permits for making every part else low-cost. Bandwidth is the irreducible bottleneck.”
