Polygon Labs CEO Marc Boiron and co-founder Brendan Farmer discussed everything about the AggLayer, a decentralized protocol built by Polygon that enables fast, secure cross-chain interactions and allows different chains to use the same native bridge. This allows users to seamlessly move assets across chains in the AggLayer ecosystem. 
The AggLayer aims to unify blockspace so that it feels like a single chain, improving user experience. Boiron and Farmer also discussed the potential for Layer 2 solutions to scale Ethereum, the benefits of zero-knowledge technology, and the future of Polygon's proof-of-stake chain.

Background of Brendan and Marc and how they joined Polygon

A brief description of what Polygon is overall

What the AggLayer is and how it aims to enable the best of monolithic and modular blockchains

How Brendan differentiates the AggLayer from its competitors, such as Optimism's Superchain or Cosmos and why he believes that zk-technology is such a game changer

How the interoperability experience gets better in such a system, according to Marc and Brendan, and what will become possible that's not now

Which chains can use the AggLayer and how it works to improve security across chains

The tradeoffs between the various types of zkEVM provers 

How projects should decide their architecture and when it would make sense to tap the AggLayer

Why projects should build on the AggLayer, including layer 1s, according to Marc

How Layer 1s can still join the AggLayer and retain their own consensus and sovereignty 

Why Polygon believes that zk-technology is the future of blockchain architecture

Why the Polgyon zkEVM suffered an outage on March 30

Whether Layer 3s are needed to scale the Ethereum ecosystem
