Rising Code Challenges

Blockchain is the hottest technology now days, and smart contracts are the business logic or a protocol according to which all the transactions on a Blockchain happen. We are talking about develop and deploy a Smart contract on Ethereum blockchain, today. So I am assuming that you are familiar with the smart contracts. You knows what is smart contract and how it’s working. I am taking a small example to store and read a value on blockchain by smart contract. pragma solidity >= 0.4 . 16 < 0.7 . 0 ; contract SolidityStorage { uint256 storedData = 5 ; function set (uint256 _x) public { storedData = _x; } function get() public view returns (uint256) { return storedData; } } This is a basic example to store a value on blockchain. Let’s explain this example. pragma solidity >=0.4.16 <0.7.0; This is the compiler version of the solidity. You can change it to your requirements. Solidity is the language which use to create smart contract...
