You work through a production-ready demo that performs private token transfers on the Chromia blockchain. Transfer amounts stay hidden from the public ledger, yet every transaction keeps its full integrity. ## Course overview The demo application covers the whole lifecycle of a private token through four core operations: 1. **Balance creation (faucet)**: Sets up public token balances so you have something to demonstrate with. 2. **Shield operation**: Uses ZKP to turn public tokens into private notes. 3. **Private transfer**: Moves private tokens from one user to another with full privacy and smart consolidation. 4. **Unshield operation**: Uses ZKP to turn private notes back into public tokens. After finishing the course, you will know how these pieces combine into a secure, private token system on Chromia. ## Key features The system you study includes these features: * **Complete privacy**: ZKP keeps both balances and transfer amounts hidden. * **Bank-grade security**: Keys are derived hierarchically and protected with password-based encryption. * **Smart consolidation**: Notes are consolidated automatically, so transfers go through without extra steps. * **Cross-user encryption**: Notes are shared securely between users with asymmetric encryption. * **Production ready**: Includes session management, auto-lock, and enterprise security. * **MetaMask integration**: Connects to the wallet and manages accounts without friction. * **Modern UI**: A straightforward interface that updates balances in real time.
