## Deploying to Testnet How to deploy our smart contracts to the Rinkeby testnet --- Different types of Ethereum networks: - Local (Ganache, Geth, OpenEthereum, etc.) - Test (Ropsten, Rinkeby, Kovan, Görli, etc.) - Main (only one) --- **Why deploy to a testnet?** --- Test your dapp before release! Smart contracts are immutable once deployed --- We'll be using the Rinkeby testnet Instead of PoW or PoS, Rinkeby is a proof-of-authority network --- **Proof-of-Authority** Uses predetermined trusted entities to reach consensus Pros? Cons? --- ### Obtaining free Ether on Rinkeby --- ### Deploying from Remix with MetaMask --- ### Deploying our Truffle project with Infura --- ## Project Status Update Deploy your dapp on a testnet and show it off to the class!
