EVM Package

The EVM package implements the Luxd VM interface.

VM

The VM creates the Ethereum backend and provides basic block building, parsing, and retrieval logic to the consensus engine.

APIs

The VM creates APIs for the node through the function CreateHandlers(). CreateHandlers returns the Service struct to serve Subnet-EVM specific APIs. Additionally, the Ethereum backend APIs are also returned at the /rpc extension.

Block Handling

The VM implements buildBlock, parseBlock, and getBlock and uses the chain package from Luxd to construct a metered state, which uses these functions to implement an efficient caching layer and maintain the required invariants for blocks that get returned to the consensus engine.

To do this, the VM uses a modified version of the Ethereum RLP block type here and uses the core package's BlockChain type here to handle the insertion and storage of blocks into the chain.

Block

The Block type implements the Luxd ChainVM Block interface. The key functions for this interface are Verify(), Accept(), Reject(), and Status().

The Block type wraps the stateless block type here and implements these functions to allow the consensus engine to verify blocks as valid, perform consensus, and mark them as accepted or rejected. See the documentation in Luxd for the more detailed VM invariants that are maintained here.
