Smart contracts in Ethereum get executed through a process called mining and validation on the Ethereum blockchain. When a smart contract is deployed, it becomes part of the Ethereum network's immutable ledger. Here's how the execution process generally works:
Deployment: A developer writes the smart contract code, usually in Solidity, and deploys it to the Ethereum blockchain using a transaction. This deployment transaction contains the bytecode of the smart contract and specifies the initial conditions, constructor arguments, and other relevant parameters.
Inclusion in Blocks: Once the deployment transaction is submitted to the network, miners compete to include it in a block. Miners collect pending transactions, including smart contract deployments, and validate them according to the consensus rules of the Ethereum network.
Execution: After a smart contract is deployed and included in a block, it becomes part of the Ethereum blockchain. From this point on, the smart contract can be invoked by users or other contracts. When a function within the smart contract is called, a new transaction is created, specifying the contract address and function parameters.
Mining and Validation: Miners process and validate the transaction containing the smart contract function call. They execute the code of the smart contract function in a simulated environment known as the Ethereum Virtual Machine (EVM). The EVM ensures that the execution of the smart contract function is deterministic and produces the same result for all nodes in the network.
Consensus: Once the transaction is validated and included in a block by the miners, it becomes part of the Ethereum blockchain. The state changes resulting from the execution of the smart contract function are recorded on the blockchain, and the transaction is considered finalized.
Confirmation: The smart contract function's execution is confirmed, and the results are visible to all participants in the Ethereum network. Users can query the blockchain to verify the outcome of the smart contract function call.
In summary, smart contracts in Ethereum are executed through a combination of decentralized mining and validation processes, ensuring the integrity and immutability of the blockchain. Smart contract development involves writing and deploying code that can be executed autonomously and trustlessly within the Ethereum network.
