# NanCoin ¤ — The Nullar Protocol

> NanCoin is a conceptual art project: a cryptocurrency permanently pegged to absolute zero. Maximum supply ¤0, every balance ¤0, ownership 100%. Everyone already owns the maximum. It has no monetary value, no ticker, no token contract on any blockchain, and is not an investment. Code and content are CC0 (public domain).

- Consensus: Proof of Nothing. Network: Nullar Mainnet. Blocks: 1 (Genesis Block #0). Finality: Absolute.
- Maximum supply ¤0. Circulating supply ¤0. Your balance ¤0. Ownership 100%.
