In the age of abundance, proof-of-origin is your most valuable asset. Numbers Protocol is building a decentralized network that makes provenance a universal standard of truth for digital assets. The future of AI depends on the integrity of its training data. Numbers makes it possible to trace, prove, and protect human content and real-world assets at the source. ## Core Technology - [Capture Cam](https://numbersprotocol.io/build): The first decentralized Web3 camera app that registers digital media with blockchain-backed provenance at the moment of creation - [ERC-7053](https://numbersprotocol.io/blog/erc-7053-transforming-digital-media-provenance-for-the-modern-web): Interoperable Digital Media Indexing standard for blockchain-based provenance - [C2PA Integration](https://numbersprotocol.io/blog/what-is-c2pa-add-c2pa-easily-with-capture): Coalition for Content Provenance and Authenticity implementation for content verification - [Numbers Blockchain](https://numbersprotocol.io/blog/numbers-mainnet-ushering-in-a-new-era-of-digital-media-trust): Carbon-neutral, sustainable blockchain infrastructure for digital media provenance - [ProofSnap Mobile](https://numbersprotocol.io/proofsnap#mobile): Field reporter-ready camera that seals photos and videos with on-chain credentials at capture time - [ProofSnap Browser Extension](https://numbersprotocol.io/proofsnap#extension): One-click web capture tool that stores full-page snapshots, source code, and metadata with C2PA credentials ## Key Use Cases - [Digital Authenticity](https://numbersprotocol.io/blog/what-is-provenance-and-why-we-need-it): Combating AI-generated misinformation and ensuring content authenticity - [News Media](https://numbersprotocol.io/blog/redefining-visual-storytelling-how-blockchain-and-ai-empower-news-media): Ensuring integrity and provenance for visual storytelling and journalism - [War Crime Investigations](https://numbersprotocol.io/blog/exposing-the-truth-how-numbers-protocol-is-revolutionizing-war-crime-investigations-with-starling-lab-and-rolling-stone): Emmy-nominated work with Starling Lab and Rolling Stone - [Election Integrity](https://numbersprotocol.io/blog/how-c2pa-and-blockchain-verify-election-news-and-combat-misinformation): Verifying election media and fighting disinformation - [Evidence Preservation](https://numbersprotocol.io/proofsnap): Capture mobile footage and live webpages with cryptographic proof for legal and compliance workflows ## Developer Resources - [Capture API](https://numbersprotocol.io/blog/add-c2pa-label-easily-with-capture-api): Easy integration of C2PA labels and blockchain provenance - [IPFS Integration](https://numbersprotocol.io/blog/step-by-step-guide-to-seamless-data-storage): Decentralized storage for digital assets - [Build on Numbers](https://numbersprotocol.io/build): Open and decentralized network built on Web3 principles ## Community & Ecosystem - [About Numbers](https://numbersprotocol.io/about): Making provenance a universal standard of truth for assets - [Ecosystem Projects](https://numbersprotocol.io/ecosystem): Community-powered network ensuring transparency, ownership, and trust - [Blog](https://numbersprotocol.io/blog): Latest updates, technical articles, and use cases - [Use Cases](https://numbersprotocol.io/use-cases)
