We can spin up a localnet with Kurtosis and receive new execution blocks through the engine_newPayloadV3 endpoint.

After creating a Genesis block (see: #48)
and the ability to execute transactions (#21), the next step is to be able to validate transactions that come through the engine_newPayloadV3 method.

So the steps would be:

• Set the genesis block as the head of the chain. Create the initial world state.
• Receive a new execution block. Run transactions through the rEVM.
• Update the world state and compare the state root with the one specified in the block header.
• If state root is valid, set the new block as the head of the chain.
• Wait for a new execution block and repeat.

Maybe this issue can be split into smaller issues.
