 ### AggLayer v1 (AL1)
-The AggLayer is the interoperability layer at the heart of Polygon 2.0. All CDK chains connect to the AggLayer to enable features such as seamless and efficient cross-chain communication, unified liquidity, and more. AggLayer v1 (AL1), is the first version of many planned iterations that relies on ZK checks to ensure operational soundness, and a unified bridge infrastructure.

 ### Rollups
 Rollups refer to blockchain scaling solutions (in the context of Ethereum) that carry out transaction execution on L2, and then post updated state data to a contract on L1. There are different types rollups, two of the most popular being optimistic, and zero-knowledge (ZK) rollups. Follow the links below to learn more:

 ### Zero-knowledge is the key
 
-Fundamentally, building this web of ZK-powered L2s comes down to one challenge: trustless, off-chain computation. In order to scale Ethereum, one needs to preserve Ethereum’s execution logic while making it more efficient.

-The best way to accomplish this goal is through zero-knowledge cryptography as it is capable of providing verifiable proofs that attest to the integrity of off-chain computations. Otherwise, scaling technologies often have to add additional social-economic mechanisms to mediate off-chain computations. The consequence of which is delayed settlement of transactions.
