 ### 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.

 A contract on the LxLy bridge utilizes its message passing capabilities to pass arbitrary messages between L1 and L2.  This is not a separate component, and is part of the LxLy bridge's architecture.
 
 ### POL (Token)
-The POL token powers the Polygon 2.0 ecosystem through a native re-staking protocol that allows token holders to validate multiple chains, and perform multiple roles on each of those chains (sequencing, ZK proof generation, participation in data availability committees, etc.)

 ### 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:

 The Polygon Knowledge Layer consists of two parts. Firstly, documents that developers need in order to build with Polygon protocols. Secondly, resources necessary for learning about Polygon technologies.

-Polygon technologies will help developers build in an elastically scalable and unified ecosystem of ZK-powered Layer 2s on Ethereum, where users can create, program and exchange value.
+Polygon technologies will help developers build in an elastically scalable and *unified* ecosystem of ZK-powered Layer 2s on Ethereum, where users can create, program and exchange value.
 
-The Polygon 2.0 vision is a unified multichain ecosystem. A web of interoperable ZK-powered Ethereum L2s, with near-instant and atomic L2 <> L2 transactions, and designed to empower developers to build without limitations. Developers will choose to build dApps, design and launch dedicated application-specific L2 chains, or migrate existing EVM Layer 1 chains to become an L2.

-The endgame of Polygon 2.0 is for developers to build in an environment that feels and functions more like the internet. This means a blockchain ecosystem that can scale without limit, seamlessly unified, and backed by the decentralization and security of Ethereum.

 ### 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.
