Solana co-founder Anatoly Yakovenko, also known as Toly, has introduced a new concept called the “Meta Blockchain.” This approach aims to transform blockchain interoperability by consolidating data from various ecosystems into a unified, sequential stream. The framework allows developers to select the most cost-effective data availability (DA) layer in real time.
Importantly, the Meta Blockchain allows users and applications to submit transaction data to any compatible network, including Ethereum, Celestia, or Solana. It then compiles this information into a single, ordered ledger using a defined set of deterministic protocols.
There should be a meta blockchain. Post data anywhere, Ethereum, celestia, Solana, 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 cheapest currently available DA offer.
Yakovenko stated:
The Meta Blockchain maintains a consistent and verifiable order by embedding the latest block headers from all targeted DA layers within each transaction. For example, when users submit a transaction to Solana, it includes the most recent blocks from both Celestia and Ethereum. This sequencing places the Solana transaction directly after the events recorded on those other blockchains.
Optimizing Costs and Enhancing Developer Agility
Yakovenko argues that this configuration allows applications and users to choose the most cost-effective DA service at any given moment, without locking themselves into a single blockchain. This approach could prove transformative for platforms such as rollups and cross-chain aggregators, where transaction costs and processing capacity fluctuate significantly with network congestion.
Users can select the most affordable DA layer available at any given time, demonstrating that the Meta Blockchain framework empowers developers to improve both efficiency and cost-effectiveness simultaneously.
A Path Away from Centralized Sequencers
A key benefit of Yakovenko’s Meta Blockchain lies in its decentralized structure. The system uses deterministic merge rules to collect and arrange cross-chain data, eliminating the need for a centralized sequencer and ensuring transparent, trustless sequencing.
Additionally, the Meta Blockchain model aligns with the broader industry shift toward modular blockchain architecture. It structures networks to focus on distinct functions—such as execution, data availability, or consensus—and connects them through standardized protocols.
The proposal facilitates smooth coordination among various DA layers, advancing a more scalable and interconnected blockchain landscape. If implemented, the system would allow users to conduct transactions freely across different ecosystems, reduce costs, and enhance flexibility.
