"Solana Labs co-founder Anatoly Yakovenko proposes a 'meta blockchain' to improve data availability"

May 13, 2025 at 07:03 pm

"In a May 12 post on X, Yakovenko proposed a “meta blockchain” to aggregate and order data posted across multiple layer-1 chains, including Ethereum, Celestia and Solana."

Solana Labs co-founder Anatoly Yakovenko has proposed a novel data availability (DA) solution to mitigate persistent fragmentation and lack of interoperability across blockchain networks.

In a May 12 post on X, Yakovenko proposed a "meta blockchain" to aggregate and order data posted across multiple layer-1 chains, including Ethereum, Celestia and Solana. This would actually allow the meta chain to use the cheapest currently available DA offer.

Data availability layers are third-party solutions ensuring that blockchains have the necessary data to validate transactions.

"If you have a meta blockchain that aggregates and orders (e.g., with a small BLS signature) data posted by e.g., Celestia, Ethereum, Solana, and aggregates it in a meta block, and signs it with a BLS key to allow efficient verification by any chain," Yakovenko said.

"This would actually allow the meta chain to use the cheapest currently available DA offer. e.g., if Celestia is cheaper this epoch, and Solana is cheaper next epoch, the meta chain can switch. This would make DA as cheap as the cheapest L1 and enable efficient cross posting and use of any L1."

This integration would provide a simple and efficient method for transferring transactions or state updates between blockchains, fostering seamless interoperability.

Other leading blockchains are also focused on improving DA solutions. Ethereum's upcoming Fusaka upgrade, expected in late 2025, will focus on scaling the Ethereum mainnet's capacity as a DA layer by introducing EIP-7594.

This upgrade may boost Ethereum's value accrual, depending on whether existing layer-2 blockchains continue choosing Ethereum for data availability in the future, a Binance Research spokesperson told Cointelegraph.

Making data availability cheap makes everything else cheap

Furthermore, Yakovenko noted that making data availability cheaper is crucial to lower the costs associated with blockchain-based transactions.

"The point is to make data availability as cheap as possible, which in turn makes everything else cheap. e.g., if you can pay $0.05 to post a block of data on-chain, it becomes cheaper than a gasless transaction. Transaction relay becomes free as it’s a simple copy operation," he said.

Moreover, Yakovenko suggested that a more advanced solution could eliminate external sequencers by using a rule-based system to merge transactions across chains, allowing users to send transactions anywhere.

"This would allow e.g., a user to send a transaction to any chain they want (e.g., send ether to another user, or make a domain transfer on Ropsten). Transactions in different chains would be merged by a rule-based system (e.g., an STJ) to form a meta transaction that can be posted on any chain."

Aiming to align blockchain network incentives, Cardano has been working on "Minotaur," a multi-resource consensus protocol that combines multiple consensus mechanisms and networks to pay a unified block reward to multiple networks at the same time.
