Solana’s Meta Chain Vision: A Bold Step Toward Blockchain Unity
Yakovenko Proposes Crosschain Data Layer to Break Blockchain Silos
Anatoly Yakovenko, co-founder of Solana Labs, is pushing for a radical solution to one of blockchain’s oldest problems: fragmentation. In a proposal posted on May 12, Yakovenko laid out plans for a “meta chain”—a new data availability (DA) layer designed to unify crosschain data across multiple layer-1 networks, including Ethereum, Celestia, and Solana.
“This would actually allow the meta chain to use the cheapest currently available DA offer,” Yakovenko wrote on X.
At its core, the proposal envisions a shared DA infrastructure that sorts and aggregates data across blockchains, eliminating the isolation between today’s L1 chains and paving the way for seamless interoperability.
Why a Meta Chain Matters Now
The current state of blockchain architecture has created data silos. Major networks operate independently, lacking built-in mechanisms to exchange data or communicate effectively. This fragmentation hampers user experience, dApp functionality, and industry scalability.
Yakovenko’s meta chain would serve as a central point of trustless data coordination, enabling developers to write crosschain applications without worrying about technical compatibility between protocols.
Ethereum’s Coming Upgrade Also Targets DA
Solana isn’t alone in targeting the data availability layer as the industry’s next battleground.
Ethereum’s upcoming Fusaka upgrade, expected in late 2025, will introduce EIP-7594, a significant step in expanding Ethereum’s data availability capacity. If Ethereum can scale efficiently, it could maintain dominance as the preferred DA provider for existing layer-2 networks.
But as Yakovenko points out, cost is king.
“Making data availability cheap allows for making everything else cheap,” he noted. “Bandwidth is the irreducible bottleneck.”
By choosing the most cost-effective DA solution in real-time, the proposed meta chain would not only bring chains together—it could dramatically lower transaction costs across the board.
Sequencer-Free Future?
Yakovenko also hinted at an ambitious next step: removing external sequencers altogether. By adopting a rule-based protocol to merge transactions across multiple chains, users could eventually send transactions to any blockchain without intermediaries.
This kind of automation could simplify user interaction across chains while preserving security and decentralization.
The Bigger Picture: Cooperation, Not Competition
Others in the blockchain world echo Yakovenko’s call for unity. At Paris Blockchain Week 2025, Cardano founder Charles Hoskinson criticized the current adversarial state of crypto tokenomics.
“The problem right now… is the tokenomics and the market structure are intrinsically adversarial. It’s sum 0,” Hoskinson said.
Cardano’s answer? A multi-resource consensus system dubbed “Minotaur”, aiming to share block rewards across multiple networks—a practical implementation of collaborative tokenomics.
