 # Aggregation layer
 
-Polygon 2.0 envisions a protocol layer that seamlessly connects any ZK-enabled L2 or L1 chain. This layer of interoperability is referred to as the **aggregation layer**, or **AggLayer**.
+Solving the scalability problem in blockchains means scaling access to shared state and liquidity across many chains. To do so requires a new approach to blockchain architecture, namely, aggregated blockchains. Polygon Labs researchers and engineers have designed a solution–the **aggregation layer**, or **AggLayer**–which will seamlessly connect any ZK-enabled L2 or L1 chain.

 Let's take a deeper look at cross-chain transfers.
 
-First of all, we understand execution of atomic cross-chain transactions to mean that, with every set of transactions a user submits to multiple chains, the user has the guarantee that either all transactions are execute successfully or none of them is included in any chain.[^1]
