Solana co-founder proposes ‘meta blockchain’ to unite decentralized ecosystems

Solana co-founder Anatoly Yakovenko has proposed creating a “meta blockchain” designed to lower data availability (DA) costs while boosting interoperability across multiple blockchain networks.

In a May 12 post on X, Yakovenko explained that the proposed meta blockchain would not serve as a standalone layer but as an aggregator. It would gather and organize data from various chains under a unified transaction ordering system.

The key idea is to reference the latest block headers from each participating chain, enabling a shared and deterministic method for aligning transactions.

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. This would actually allow the meta chain to use cheapest currently available DA offer.”

Meta Blockchain

Yakovenko suggested that a Meta transaction on Solana could include recent blocks from Ethereum and Celestia. This approach would reduce uncertainty in transaction sequencing and allow users to benefit from the cheapest data availability solution.

The Solana co-founder further emphasized that a fixed rule for merging transactions would ensure consistency across the system. This model could reduce reliance on centralized sequencers, which are often viewed as single points of failure in many rollup ecosystems.

In his view, an ideal system would use a protocol that automatically merges data from all connected chains without needing an external coordinator.

He said:

“A lame version of this relies on an external sequencer. I think the cooler version is just a merge rule that reads all the chains. So users can send txs anywhere.”

Feasibility challenge

While the concept has sparked interest, not everyone is convinced of its practicality.

Celestia COO Nick White pushed back on the idea, noting that similar proposals, known as DA multiplexers, have long existed in theory but are rarely implemented.

According to White, such models increase operational complexity because rollups need to run nodes for each DA layer. Additionally, managing the fork-choice rules across multiple chains would significantly raise overhead, offering limited benefits in return.

However, Yakovenko remains confident that affordable and accessible data availability will lower the cost of other on-chain activities. He said:

“Making data availability cheap allows for making everything else cheap. Bandwidth is the irreducible bottleneck.”
