Espresso Systems, Polygon Labs Join Forces for Ether Scaling

Espresso Systems and Polygon Labs are teaming up to develop AggLayer, a solution aimed at addressing rollup interoperability issues.

Solution for shared sequencers Espresso Systems and Polygon Labs, developers of an Ethereum Layer 2 scaling solution, have announced their intention to work together on AggLayer, a solution to the problems of rollup interoperability.

Launched in January, AggLayer is an attempt to unify the blockchain industry’s disjointed liquidity by putting the user experience at the heart of scaling.

The AggLayer enables both quick and secure bridging and near-synchronous composability across rollups. The power to securely transport messages between rollups is what makes it possible to ensure that inputs on one blockchain are legitimate outputs from another, all at once.

Nevertheless, coordination layers are necessary for the interdependent rollup blocks to guarantee the security of cross-rollup message delivery. Espresso, as the coordinator, will ensure the unification of rollups prior to their settlement on the Ethereum network, a function on which the AggLayer will rely.

Espresso provides a platform for sequencers to buy the power to manage the ordering of transactions for multiple rollups at once. Sequencers like this make it possible for AggLayer-compatible rollups to communicate in synchronization, and AggLayer guarantees the security of these cross-chain transactions.

Also, thanks to HotShot consensus, transactions on rollups with Espresso incorporated will get preconfirmation almost instantly.

The technologies provide significant improvements to Ethereum’s security and user experience when used together. All Ethereum Layer 2 networks will be able to make use of both technologies to improve composability; therefore, the project teams will be working together to optimize Espresso and AggLayer compatibility.

Espresso Systems Raises $28 Million in Series B Funding, Debuts Cappuccino Testnet

Espresso Systems is developing a distributed network for rollup sequencers to coordinate with one another. While simultaneously participating in a system that unifies transaction sequencing across different rollups, this platform functions as a marketplace where sequencers can sell their blockspace.

Espresso Systems’ fifth testnet, Cappuccino, was recently released, signaling the impending launch of the Espresso marketplace. At the same time, a16z Crypto was the main investor in the $28 million Series B round of funding that the company had previously completed.
