Solana co-founder proposes meta chain to fix blockchain fragmentation

Solana Labs co-founder Anatoly Yakovenko proposed a new data availability (DA) solution to improve 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,” Yakovenko said.

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

Blockchain interoperability is one of the most pressing issues for Web3 developers, since today’s siloed layer-1 (L1) blockchain networks have no means of communicating or exchanging data, creating a need for crosschain interoperability solutions like DA layers.

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.

Making data availability cheap makes “everything else cheap”

Creating cheaper DA solutions is essential to reduce the costs associated with blockchain-based transactions, Yakovenko said in a response to his initial post, adding:

“Making data availability cheap allows for making everything else cheap. Bandwidth is the irreducible bottleneck.”

He also 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.”

Other prominent blockchain industry leaders have also called for more interoperability and collaborative tokenomics among the leading blockchains.

Speaking at Paris Blockchain Week 2025, Cardano founder Charles Hoskinson emphasized the need for collaborative economics in the crypto industry to counter growing competition from traditional tech firms entering the blockchain space.
