Mastering Blockchain Programming with Solidity

Life cycle patterns

A Solidity contract is created either by deploying a new contract or by creating from within a contract. Apart from these, a contract and its functions can follow a different life cycle. A Solidity contract can also be destroyed by calling the selfdestruct function. Once a contract is destroyed, it cannot be recreated on the same address. 

Similarly, using the timestamp's global variables and time units, contract states can also be moved. It is also possible to allow the contract functions to be called based on these timestamps. Let's look into the life cycle design patterns.
