Solana co-founder Anatoly Yakovenko has introduced the concept of a meta-blockchain. This idea involves placing data in any chains and then merging them into a single sequence according to established rules.
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.

“This approach aims to use the most cost-effective data availability (DA) solution at any given time,” he noted.
In its simplest form, a transaction could reference the headers of the latest blocks from potential DA layers like Ethereum, Celestia, or Solana. Thus, it would be guaranteed to be ordered after confirmation in the chains, Yakovenko described the mechanism.
According to him, this is not akin to a torrent system with a network of P2P seeders.
“This is a completely different matter. The essence is simply to use a globally agreed merging rule and not to run any network independently,” he explained.
Celestia Labs COO Nick White warned that implementing such a concept would face technical and economic challenges. For instance, it would become much more expensive to prove the canonicity of a chain for a cross-chain bridge.
People have talked about DA multiplexers for a while, they’re not that useful since then your rollup requires running a node of each of the DA layers and your fork choice rule becomes really complex, which just explodes the overhead and complexity for very little gain.
Just use…

“There have been talks about DA multiplexers for some time, but they are not very useful since their combination requires running a node of each layer, and the fork choice rules become really complex, which just sharply increases overhead and complexity for very little gain,” the expert added.
Kevin Wang, co-founder of Nervos Network, countered, suggesting that the idea of multiplexers will continue to evolve. However, solutions will be based not on DA but on state or resource locks.
multiplexing will happen but imo it’s not going to be around DA but around state/resource locks — a meta liquidity solution is simply a better product than a meta DA solution.
One opens a path to revenue; the other is a way to optimize cost

“A meta liquidity solution is simply a better product than a meta data availability solution. One opens a path to revenue; the other is a way to optimize cost,” he believes.
Earlier, ForkLog explored the concept of network abstraction in educational cards, aimed at eliminating the fragmentation of the Web3 space and simplifying cross-chain interactions.
