- Polygon and Espresso work together to address the fragmented liquidity in the blockchain industry.
Developer of shared sequencers Espresso Systems and Ethereum layer-2 scaling solution Polygon Labs have teamed up. The partnership aims to develop and create an aggregating layer (AggLayer) that may be able to address the issue of fragmented liquidity between interoperable rollups.
The goal of AggLayer, which debuted in January, is to facilitate transaction verification throughout several chains by use of a procedure known as “proof aggregation.”
By doing this, it guarantees the validity of transactions between its ecosystems without depending on outside bridge solutions. According to Polygon Labs documentation, every transaction on AggLayer will be guaranteed, giving users a flawless experience.
A decentralized system called the Espresso Shared Sequencer connects various L2s by acting as both a sequencer and a data availability point. To better accomplish autonomy, neutrality, and cooperation among EVM chains, an architecture of this kind improves credibility, interoperability, and alignment with Ethereum.
Other initiatives, including Nil Foundation, are also developing integrated or modular solutions to Ethereum’s scalability problem. In contrast, Nil Foundation is focusing on “horizontal” scaling by integrating the sequencer into a protocol to facilitate transactions across several shards, whereas initiatives like zkSync are targeting “vertical” scaling.
Espresso had already received huge funding, including $28 million from a Series B round headed by a16z crypto. Espresso is noteworthy because it acts as a shared sequencing marketplace where rollups can bid on the right to construct their blocks.
Through an auction, rollups can provide sequencing timeslots to shared sequencers thanks to this market. From this end, Espresso will serve as the coordinator to bring all of the interconnected rollups together before Ethereum settlement.
