Solana’s co-founder Anatoly Yakovenko, popularly known as Toly, has proposed a new idea that’s capturing attention in the crypto community: a “Meta Blockchain. ” The concept is straightforward, at least in theory. Data can be posted on any chain—Ethereum, Celestia, Solana, or others—and then all that data would be merged into a single, ordered history by applying a shared rule. The innovative part?This approach would allow apps or users to pick the cheapest data availability layer at any moment, instead of being limited to just one chain. “There should be a meta blockchain, ” Toly tweeted. “Post data anywhere…and use a specific rule to merge data from all the chains into a single ordering. This would actually allow the meta chain to use the cheapest currently available data availability offer. ” He elaborated on the mechanism: a transaction posted on Solana (dubbed a MetaTX) would carry block headers from Ethereum and Celestia. In this way, the transaction would be provably ordered after related activity on those chains at that time. There’s no need for guesswork or centralized control—just a universally agreed-upon ordering rule. But what about a torrent-like system? Developer Belac offered his twist: “What if the meta chain were a peer-to-peer node/seeder network?

Like a torrent system that stores multi-chain data in pieces, with participants earning by seeding historical blocks. This might solve the history problem and make the system community-operated. ” It’s an intriguing idea, definitely aligned with decentralization principles—but Toly was less enthusiastic about that route. “That’s a completely different thing, ” he replied. “The whole point is to use a globally agreed-upon merge rule without running a network yourself. ” Why is this important? If realized, it could revolutionize how developers work across multiple chains. Imagine writing once, posting anywhere, and obtaining a single, unified history—all while choosing the chain offering the best data availability price at the time. In today’s modular blockchain landscape, projects often experiment with combinations: one chain for execution, another for data, perhaps yet another for consensus. Toly’s suggestion fits snugly into this trend but streamlines it by avoiding the need to establish an entirely new network. It functions more as a protocol-level rule than a full infrastructure rebuild. Moreover, it could be especially impactful for rollups, aggregators, or any applications managing extensive cross-chain operations. Tracking events across different chains is complicated, and this approach might provide a simpler, cost-effective solution. So, what’s next? There’s no whitepaper, no GitHub repository, no developer network—just the tweet. But sometimes, that’s enough to spark something big. The Meta Blockchain idea is still just in its infancy—but in a space where ideas propagate rapidly and unconventional solutions succeed, it wouldn't be surprising if a prototype emerges sooner rather than later.
