Bitcoin-backed rewards that increase in purchasing power over time

Bitpoints.me is an open-source wallet merging proven privacy and interoperability protocols: Cashu ecash for private bearer tokens, Nostr for decentralized identity, and Bluetooth mesh networking (from BitChat) for offline peer-to-peer transfers.

Unlike traditional points that lose value to inflation, Bitpoints are denominated in Bitcoin (sats). As Bitcoin's purchasing power increases, so do your rewards. What buys a coffee today might buy lunch tomorrow.

Built on open protocols, Bitpoints work with any merchant accepting Bitcoin or Lightning. Your rewards aren't locked to one business—spend them anywhere in the global Bitcoin economy.

• Cashu ecash protocol: Bearer tokens with no transaction history
• No accounts or tracking: Your spending is your business
• Offline-capable: Send and receive without internet via Bluetooth mesh

Every component is open source and based on established protocols:

• Cashu: Chaumian ecash for Bitcoin
• Nostr: Decentralized identity (NIP-05, NIP-60)
• BitChat Mesh: Noise Protocol-encrypted Bluetooth mesh networking

• Bearer tokens with no transaction history
• End-to-end Noise Protocol encryption for all mesh transfers
• Ephemeral peer IDs prevent tracking
• No personal data collection

• Offline transfers: Send/receive without internet
• Multi-hop relay: Reach peers up to 7 hops away
• Peer discovery: Find nearby Bitpoints users automatically
• Broadcast mode: Send rewards to all nearby users
• Noise Protocol encryption: Military-grade E2E encryption
• Battery optimized: Adaptive duty cycling

• Receive via Lightning address: [email protected]
• Auto-claim tokens from Lightning payments
• NIP-05 verified identity
• LNURL-pay support

• Non-custodial: You control your keys
• Social backup options (NIP-60 encrypted to trusted contacts)
• Seed phrase derived from wallet (one backup for everything)
• Open source and auditable
