# Numbers Protocol > Provenance infrastructure for humans and AI Numbers Protocol is a decentralized provenance protocol that records, tracks, and verifies the origin and history of digital media on blockchain. Numbers Protocol provides infrastructure for recording and verifying the provenance of digital media and real-world assets on blockchain. Users can register content on-chain, verify authenticity through asset profiles and reverse-image search, and declare how their work may be used in AI training. The protocol uses open standards including C2PA, ERC-7053, and ERC-7517, and operates the Numbers Mainnet as a dedicated provenance blockchain. - Type: Protocol - Sector: Infrastructure - Status: Active - Founded: 2022-12-01 - Profile: https://thegrid.id/profiles/numbers_protocol ## Products - [Numbers Protocol](https://thegrid.id/profiles/numbers_protocol): Numbers Protocol is a provenance infrastructure protocol enabling digital media creators and organizations to establish verifiable on-chain records of asset origin and modification history. It uses ERC-7053, an indexing standard for EVM-compatible blockchains, to assign unique identifiers to media assets and log changes through a Git-style commit system. The protocol includes a verification engine with reverse-image search and cross-chain provenance lookup for registered media assets. (Cross-chain Infrastructure, Live, Main Product) - [Numbers Blockchain](https://thegrid.id/profiles/numbers_protocol): Numbers Blockchain is an EVM-compatible blockchain built as an Avalanche Subnet, providing on-chain infrastructure for digital media provenance. Operating with Chain ID 10507 and NUM as its native currency, the network restricts deployments to media provenance-related smart contracts. It implements the ERC-7053 indexing standard, allowing applications to log verifiable media records accessible through a public block explorer. (L1, Live) - [ProofSnap](https://thegrid.id/profiles/numbers_protocol): ProofSnap is a content authenticity application available as a mobile app and browser extension that seals media captures with verifiable provenance. The mobile app locks GPS coordinates, device ID, and timestamps on the Numbers Blockchain alongside C2PA credentials at capture time. The browser extension creates timestamped screenshots of web pages with tamper-proof metadata sealed on IPFS and the blockchain for legally documentable evidence. (Decentralised Identity, Live) - [Capture](https://thegrid.id/profiles/numbers_protocol): Capture is a Web3 media management platform for creating, registering, and monetizing digital content with on-chain provenance on the Numbers network. It provides a mobile camera application for recording media directly to the Numbers Blockchain, a dashboard for managing authenticated digital assets, and a developer SDK for integrating provenance features into applications. An embeddable widget, Capture Eye, enables web publishers to display content credentials and support direct media purchases. (Developer Tooling, Live) ## Assets - [NUM Token (NUM)](https://thegrid.id/profiles/numbers_protocol): NUM is the utility token of Numbers Protocol. It is used for paying provenance protocol fees on ERC-7053 content records, staking to secure the Numbers Mainnet, and participating in governance. Each ERC-7053 provenance write on Numbers Mainnet requires NUM as a protocol fee, separating proof creation from value settlement, which uses stablecoins.
