Capture

Powered by Numbers Protocol, Capture is a toolset that registers images and videos as on-chain assets, delivered as a web dashboard, an iOS app and multi-language SDKs. The pain point it addresses is that, with generative content everywhere, it is hard to prove where material came from and when: files are signed with C2PA content credentials at capture time, registration records are written on-chain under the ERC-7053 standard, originals are stored in decentralised storage, and licence terms for editorial, commercial and training use can be set on-chain.

The asset page records the content identifier, creator, timestamp and signature information for third parties to verify; developers embed signing into their own products with the SDK, and the dashboard supports batch uploads of up to 1,000 files. The product targets photographers, newsrooms and archives, and media files can be registered in batches and listed in a licensing marketplace. The ProofSnap app and the SDKs are free, while registration and signing are billed per call. In the content provenance category Capture is discussed as a C2PA implementation.
