Introduction solidity
- 2. Plan 1. Smart contract bases 2. Solidity syntax 3. Workshop: create your subcurrency ERC20
- 3. Bases ◎ Feature => it must do what it has to do ◎ “Code proof” => security gapes (ex: reentrency with theDAO, visibility function with multisig parity) ◎ “Cryptoeconomic proof” => good incentives (ex: random number for gamling) ◎ Optimize complexity => cf. gas, big O ◎ Optimize storage => cf. state variable, types 5 challenges to develop a smart contract:
- 4. Bases Smart contract must be perfect before the production
- 5. Solidity Syntax https://remix.ethereum.org ◎ Variables & operators ◎ Conditions and loops ◎ Input and output parameters
- 6. Create subcurrency - specifications (mvp) ◎ Supply is limited and defined by the creator ◎ People can transfer to another wallet ◎ Credit (balance < 0) is not authorize
- 7. Create subcurrency - specifications ERC20 https://github.com/ethereum/EIPs/blob/master/ EIPS/eip-20-token-standard.md Let’s go!
