Hashcash PoW Faucet

This project is a tribute to Hashcash and early cypherpunks and combines two ideas:

• Hashcash-style Proof of Work: Every signup and claim requires solving a stateless PoW challenge, inspired by the original Hashcash anti-spam mechanism proposed by Adam Back in 1997.
• Crypto-inspired accounts: Each user gets a “private key” after a PoW signup challenge that is stored in their browser and used to authenticate with the server. The server tracks your credits using an address derived from his private key, similar to a very simple wallet address, but never stores the key itself.
• Redeem mechanism and DEX: You can redeem by burning Credits for small tips in supported cryptocurrencies. An experimental, non-custodial P2P DEX also lets you trade Credits for VECO (more coins may be added later).
• No registration or personal data: You can create and use an account without email, username, or KYC. The server only sees anonymous keys and derived addresses, and there is no traditional signup form.
• Limited account creation per IP/day: For fairness and to limit abuse, this demo only allows a limited number of signups per IP address per day.
