Facecoin

Proof of Face: A Cryptocurrency Powered by Machine Pareidolia

Facecoin is a sovereign rollup on Celestia where participants mine FACE tokens by finding inputs whose visual representations contain machine-detectable faces. Miners search locally for nonces that produce face-like images, then submit proofs as transactions. The chain verifies the claim, awards FACE tokens, and mints the face image as an NFT.

Block production is handled by a standard sequencer -- Proof of Face lives entirely at the application layer, making the chain deployable with off-the-shelf Celestia rollup frameworks.

This project extends Rhea Myers' 2014 conceptual artwork Facecoin and draws on Clovers Network's proof-of-search model.

Key Features

• Proof of Face mining -- find machine-perceived faces in hash-derived images, submit proofs as transactions
• Dynamic difficulty -- face detection confidence threshold adjusts with mining activity
• Native NFTs -- every valid proof mints a face image NFT for the miner
• FACE token -- native currency with halving emission schedule
• Sovereign rollup on Celestia -- standard sequencer for blocks, Celestia for data availability
• Minimal custom code -- only the face detection module is custom; everything else is off-the-shelf Rollkit + Cosmos SDK
• Bridgeable -- tokens and NFTs can bridge to Ethereum and Solana
