Shared sequencer resolution Espresso will associate with Ethereum layer-2 scaling resolution Polygon Labs to develop AggLayer (aggregation layer) in an effort to remedy rollup interoperability.
AggLayer was first launched in January. It’s designed to unravel the fragmented liquidity drawback within the blockchain house by centering scaling UX on one single, unified aggregation layer. AggLayer is just like Risc Zero’s “Kind 0” zkEVM, Zeth, a general-purpose programming language that may be EVM equal.
Each options are designed to allow transaction verification throughout a number of chains. Within the case of AggLayer, the protocol makes use of a course of referred to as “proof aggregation” to make sure that transactions throughout its ecosystems are legitimate.

In response to Polygon Labs paperwork, all transactions shall be assured on AggLayer with out having to depend upon a third-party bridging resolution.
In the long run, Polygon hopes that when a rollup creates a message for a vacation spot chain, it’ll additionally create a validity proof that verifies its accuracy instantaneously.
That’s one drawback that Anurag Arjun, the founding father of Avail, and his workforce are hoping to resolve.
Arjun notes that though cross-chain communication is nice for customers who belong to the identical ecosystem, as soon as they go away the ecosystem, they’re more likely to obtain a “subpar expertise.”

“If you wish to actually carry these rollups collectively, you want two issues primarily,” Arjun informed Blockworks. “You want a proof of ordering — the transaction knowledge ordering — within the sense that if a rollup has dedicated to a sure order of the transactions, you want some ensures for that. That’s what Avail validity proof [data availability sampling] supplies. And you then want the execution proofs, that are offered by the rollup themselves.”
The excellence that must be made is that proof aggregation itself just isn’t sufficient, and transaction ordering of those rollups is equally vital, Arjun mentioned.
“So whenever you mix ordering ensures with the precise execution proof, then that’s the reason we’re ready to do that orchestration — connecting these rollups,” he defined.
Nonetheless, the state of proving at this cut-off date just isn’t but on the pace of real-time verification, and all interdependent rollups have to be created, aggregated and verified collectively earlier than they’re settled on Ethereum.
That is the place Espresso is available in. Espresso would be the coordinator that unifies the interdependent rollups earlier than they’re settled onto Ethereum.
Ben Fisch, the CEO of Espresso Labs described the collaboration efforts between Espresso and Polygon as pivotal for each ecosystems.
“Our respective groups have been considering deeply about layer-2 interoperability during the last 12 months — it’s superb to see our options converge in such a synergistic approach. Polygon’s AggLayer and Espresso’s coordination layer are excellent enhances,” Fisch informed Blockworks.
Marc Boiron, CEO of Polygon Labs, shares this sentiment. He informed Blockworks he believes this new partnership will synergistically elevate interoperability inside Ethereum’s layer-2 setting.
“Whereas the AggLayer ensures the integrity of information trade amongst Ethereum layer-2s, Espresso’s sequencing market optimizes this course of by enabling environment friendly coordination and quick transaction finalization throughout a number of Ethereum layer-2s,” Boiron mentioned. “This built-in strategy markedly enhances the fluidity and consumer expertise of transactions inside Ethereum’s layer-2 community.”
Espresso’s newest partnership with Polygon on AggLayer exhibits the progress of the modular strategy to scaling Ethereum, one which stands in distinction to what, for example, the Nil Basis is working to realize with sharded layer-2s.
Misha Komarov, the founding father of Nil Basis, beforehand informed Blockworks that it goals to take a protocol-level strategy to interoperability by embedding the sequencer into the protocol to make it able to sending transactions between completely different shards.

“So mainly, which means it retains all of them composable, it retains all of them collectively, it retains the liquidity unified. It’s like no separation, no Balkanization of ETH is occurring, in actual fact,” Komarov mentioned.
In easier phrases, the 2 approaches may be seen as vertical versus horizontal scaling, although they mixed options of each to various levels.
“ZkSync and Polygon pursue vertical scaling — layer-2s and layer-3s — [while] on our aspect, we pursue horizontal scaling,” he mentioned. “We form of say, okay, modularity may be achieved in a greater approach. It is perhaps not even the modularity anymore.”
Whichever strategy finally prevails, there’s a widespread recognition that the fragmentation of UX and liquidity that presently prevails throughout many Ethereum scaling efforts is an obstacle to adoption.
“This complete trade is a contest of concepts,” Komarov provides. “A contest of who will get the higher concept and the primary one who will get there — the implementation of it — captures the market.”
