An Ethereum node needs to do three things in order to send smart contracts to the blockchain:
1) It needs to compile the solidity code into EVM bytecode
2) It needs to deploy the bytecode to the blockchain
3) It needs to interact with the deployed contract to execute its code
In order to compile the solidity code, the node needs to have the solidity compiler installed. The solidity compiler turns the high-level solidity code into EVM bytecode, which can be run on the Ethereum Virtual Machine.
Once the bytecode has been generated, it needs to be deployed to the blockchain. This can be done with the help of a smart contract deployment tool, such as the Truffle framework.
Once the contract has been deployed, the node needs to interact with it in order to execute its code. This can be done using the Ethereum RPC API.

Q: How is smart contract deployed in blockchain?
A: There is no one-size-fits-all answer to this question, as the deployment of a smart contract on a blockchain will vary depending on the specific platform being used. However, in general, a smart contract is deployed by first deploying the code to the blockchain, and then deploying the data associated with the contract (i.e. the contract’s “state”).
Q: How does Ethereum execute smart contracts?
A: Ethereum executes smart contracts by running a virtual machine on each node in the network. The virtual machine, called the Ethereum Virtual Machine (EVM), is responsible for executing the code of the smart contract.
Q: How are smart contracts stored on the ethereum Blockchain?
A: Smart contracts are stored on the blockchain just like any other transaction. They are immutable and can be viewed by anyone on the network.
Q: How does Ethereum work in depth?
A: Ethereum works by maintaining a shared ledger of all transactions that have ever occurred on the network. This ledger is called the blockchain, and it is stored on every computer that runs the Ethereum software. Whenever a new transaction is made, it is added to the blockchain, and all of the computers on the network update their copies of the ledger. This ensures that everyone has the same record of all transactions, and no one can fraudulently add or change any entries.
In order to make a transaction, you need to have a certain amount of “ether” – the currency of the Ethereum network. Ether is created through a process called “mining”, and it can be bought and sold on exchanges.
When you make a transaction, you specify what action you want to happen. This could be something like sending ether to another person, or it could be a more complicated action like creating a new smart contract.
Your transaction is then sent to the network, where it is verified by miners. Once it is verified, it is added to the blockchain and the action is executed.
