=====================================

Overview of a smart-contract life-cycle

Smart-contract deployment
-------------------------

- Smart contracts are deployed through transactions
    - The developer only needs to send a contract creation to the network
    - This transaction will contains the contract’s code
- Once created, the contract will have its own account
    - Its own address
    - Its own balance


Smart-contract calls and executions

- Smart contracts are called through transactions
- To call a contract you need its address
- If Bob wants to call a contract, he needs to send it a transaction
    - The transaction will contains the informations regarding which function he calls and what are the parameters (it required)
