Encrypted messaging on a Proof-of-Stake blockchain.
DigitalNote is a hybrid PoW/PoS cryptocurrency with native encrypted messaging, zero-knowledge STARK proofs, masternodes, an on-chain social protocol, and a name registry — reimplemented from the ground up in Rust.

- Encrypted Messaging (SMSG) — End-to-end encrypted, relayed through masternodes. Ephemeral (1h), standard (24h), extended (7d), persistent (30d), or anchored on-chain permanently.
- zk-STARK Proofs — Message authentication via hash-based zero-knowledge proofs. No trusted setup. Quantum-resistant.
- Social Protocol — Posts, follows, tips, replies, threads, topic feeds. All at the protocol level with cryptographic identity.
- Federation / ActivityPub — XDN nodes speak ActivityPub. Posts and profiles bridge to the fediverse (Mastodon, Pleroma, etc.) — extending the social layer beyond the XDN network with end-to-end encryption advantages no standard fediverse server can match.
- Name Registry (XNS) — Human-readable names registered on-chain via OP_RETURN. Fees burned (10 XDN–10,000 XDN depending on length).
- Masternodes — 2M XDN collateral. Message relay, transaction locking, sidechain validation, governance.
- Tithe System — Voluntary per-block donation from staking rewards. Configurable percentage and destination.
