Welcome back to Day 10 (and the last day!) of my blockchain series. In this video I take the console Rock Paper Scissors dApp we built with Reach and actually deploy it to the Algorand TestNet. If “deploying to a blockchain” sounds scary, I promise it’s not—I walk through the exact differences between Reach’s local devnet (fast, private, great for development) and Algorand’s public testnet (a mirror of mainnet, but with worthless tokens—think Monopoly money). The big takeaway: testnet behaves like the real world, including confirmation times and public transaction history. I show you how I create and fund real testnet accounts using MyAlgo Wallet, including the important security bits around the 25-word mnemonic (seed phrase) and why you should never share it. Then we update the app config: switch the provider network to testnet, stop auto-creating accounts, and load accounts from mnemonics instead. Finally, I set the connector mode to ALGO-live, deploy the contract, accept the wager, and play a full round—so you can see the ~5 second block confirmation time in action. To wrap up, I inspect the transactions in the Algorand explorer, explain deposits vs wagers, and even decode an argument to prove that what you commit on-chain is public. Congrats—you just shipped a dApp to a real consensus network.
