Hashcash PoW Faucet

This small 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 this browser and used to authenticate with the server. The server tracks your HCC using an address derived from this private key, similar to a very simple wallet address, but never stores the key itself.
• 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 (demo rule): For fairness and to limit abuse, this demo only allows a limited number of signups per IP address per day.

Disclaimer: Credits (Hash Cash Credits - HCC) in this demo are play points only. They have no monetary value, do not represent a claim against us and have no fixed or implied exchange rate. Any crypto tip is purely discretionary, may be small, irregular or skipped entirely, and can be changed or discontinued at any time. There is no guaranteed probability, minimum or maximum payout and no right or expectation of any payment. The displayed ranges are not guaranteed and are provided for guidance only. The experimental DEX is non-custodial: we do not hold or escrow your coins; payments are made directly on-chain between users. Trades may fail, expire, or be delayed (including due to network conditions, confirmations, wrong amounts, or chain reorgs). Use at your own risk.
