The pursuit of enhanced efficiency and interoperability within the blockchain sphere continually drives innovation. A notable recent contribution to this discourse comes from Anatoly Yakovenko, a co-founder of Solana, who has introduced the intriguing concept of a “metablockchain” designed to bridge disparate networks.
Yakovenko’s Vision: The Metablockchain
Yakovenko envisions a system capable of consolidating data from various blockchains, including prominent players like Ethereum, Celestia, and Solana itself. The core objective is to establish a unified transactional order across these otherwise distinct ecosystems. He suggested that such a “meta blockchain” could allow data to be posted across any of these chains, with a specific rule merging this information into a single, coherent sequence. A key advantage highlighted is the potential for this overarching structure to dynamically select and utilize the most cost-effective Data Availability (DA) solution available at any given moment.
Potential Mechanics and User Benefits
Illustrating the concept, Yakovenko explained that a metatransaction could, for example, be anchored on the Solana network while incorporating the latest block headers from Ethereum and Celestia. This mechanism would ensure that the transaction’s placement in the overall order respects all preceding events on the connected chains, thereby maintaining consistency. Such a design could offer users a valuable choice between transaction finalization speed and cost. He also noted the feasibility of a hybrid approach, provided that the rule for merging data from different chains is deterministic and predictable.
Industry Perspectives and Challenges
Yakovenko’s proposal has sparked discussion among other developers in the space, eliciting both support and cautious skepticism.
Supportive Views and Explorations
Nader Dabit, a developer associated with EigenLayer, expressed enthusiasm for the idea, noting that he had previously encountered an attempt to build something similar leveraging EigenDA and Celestia. Dabit indicated an intention to investigate the progress of that earlier project. In response to a query about Solana itself serving as a DA layer, Yakovenko emphasized that Data Availability must be inexpensive to reduce the cost of all other system components, identifying throughput as the primary bottleneck.
Concerns Over Complexity
However, not all reactions were unreservedly positive. Nick White, a co-founder of Celestia, voiced concerns about the potential for such “DA multiplexors” to become overly complex. He argued that these systems might not be very practical, as rollups would need to operate nodes for every integrated DA layer. Furthermore, White suggested that the rules for determining the correct chain fork could become excessively convoluted, ultimately leading to unnecessary operational overhead without delivering substantial commensurate benefits.
