Solana Labs co-founder Anatoly Yakovenko has proposed a new data availability (DA) solution to address blockchain fragmentation and interoperability issues. In a post on X, Yakovenko suggested the concept of a “meta blockchain” that can aggregate and order data from various layer-1 chains like Ethereum, Celestia, and Solana. This meta chain would utilize the most cost-effective DA offer available, according to Yakovenko. Data availability layers play a crucial role in ensuring that blockchains have the required data to validate transactions. Blockchain interoperability is a major concern for Web3 developers as current siloed layer-1 blockchain networks lack communication channels, necessitating cross-chain interoperability solutions such as DA layers. Ethereum’s upcoming Fusaka upgrade aims to enhance its capacity as a DA layer with the introduction of EIP-7594. This upgrade could potentially increase Ethereum’s value accrual if layer-2 blockchains continue to choose Ethereum for data availability. Yakovenko emphasized the importance of creating affordable DA solutions to reduce transaction costs associated with blockchain activities. He suggested that eliminating external sequencers and using a rule-based system to merge transactions across chains could further enhance interoperability. Industry leaders like Charles Hoskinson have also stressed the need for collaborative tokenomics and interoperability among leading blockchains to counter the competition from traditional tech firms entering the blockchain space. Cardano’s Minotaur protocol aims to align blockchain network incentives by combining multiple consensus mechanisms and networks to pay a unified block reward. By addressing these issues, the blockchain industry can move towards a more cooperative and sustainable equilibrium.
