Execution Layer
The Execution Layer is the component of a blockchain architecture where smart contracts are run and transaction state changes are computed. It is where the logic of decentralized applications is processed, turning raw transaction data into updated balances and states.
By separating the execution layer from the consensus layer, developers can innovate on how code is run without needing to change the underlying security and ordering rules of the network. This modularity allows for the creation of specialized execution environments that can handle different types of assets or complex computations.
It is the layer that users interact with directly when they swap tokens or mint NFTs. Security in this layer depends on the correctness of the code and the robustness of the virtual machine.
It is the primary site of innovation for decentralized finance protocols.
