Smart Contract Implementation

Beyond the Basics

• Smart contracts are immutable programs that can be used by the Ethereum blockchain. They cannot be changed once they are deployed therefore it is a sound commitment by both parties.
• Solidity: Language that smart contracts will be written in
  • Solc: Solidity compiler, used to compile smart contracts to return the ABI and Bytecode of a smart contract
    • ABI: Application Binary Interface
      • An array of function definitions to be used by our application
    • Bytecode:
      • Bytecode that is read by the Ethereum Virtual Machine, this project does not go further in depth of the EVM
• Ethersjs
  • Javascript library that’s developed to use smart contracts. It’s easy for beginners, and allows for simple contracts to be created and deployed
• Python compiler server
  • Meteor is unable to utilize Solc internally, so all smart contracts will be compiled by a python script on a server external to the app
• Ethereum network
  • Using the Ganache application by HardHat as a test network
    • Simulated the Ethereum blockchain
    • Keep track of transactions easily
    • Has a GUI for ease of use
  • May possibly create an assortment of dummy accounts with metamask and utilize Ethereum test networks that are available.
