Book of Secrets
1st Place Citrea HackBook of Secrets is a Bitcoin native dApp built on the Citrea Testnet to showcase privacy, ownership, and on chain creativity. Every user owns a personal on chain diary, each page holding an encrypted secret.
Secrets are encrypted with AES 256 before they ever hit the chain. Unlocking is dual path: a password hash check, or a cBTC payment gate so the writer can monetize a reveal. Won 1st place ($80) at the Citrea Hackathon.
- On chain diary: every page is a permanently stored encrypted secret
- AES 256 encryption before write, password hash or cBTC payment to unlock
- Built with ethers.js v6, Solidity, and Hardhat on the Citrea Testnet
