Blockchain as a repository of data is a use case that is also being debated. Anatoly Yakovenko, co-founder and CEO of Solana Labs, floated the idea of a meta blockchain, a hypothetical structure that would solve the problem of cheap data availability in the digital space.

In social media, Yakovenko commented on the idea, explaining that this meta-blockchain would be an aggregation of blocks coming from different chains, including Solana, Celestia, and Ethereum. He stated:

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.

Furthermore, Yakovenko explained that this would allow for taking advantage of the cheapest data availability offering at each moment.

While the price of onchain data might seem cheap across several blockchains at the moment, Yakovenko’s proposal would cater to projects focused on saving large datasets on-chain. “Making data availability cheap allows for making everything else cheap. Bandwidth is the irreducible bottleneck,” he stressed.

The meta-blockchain proposal would also improve the decentralization and availability of this information due to its distribution across several blockchains, even when there are currently specialized projects targeting this use case. “User can pick the fastest finality vs price. I think a mix would make sense as long as the merge rule is deterministic,” Yakovenko assessed.

Additionally, Yakovenko also explained how this could become a reality, proposing a transaction structure to make it possible. “Simple way to do this would be for the tx to reference the latest block headers from the potential DA layers. So MetaTX posted to Solana would include the last observed block from eth and celestia,” he stressed.
