OP vs NFT Verification
NFTs create a blockchain record of ownership — but anyone can mint someone else's photo as an NFT. The blockchain proves who minted it, not who captured it. NFTs don't verify that the content itself is authentic or unaltered.
Where NFT Verification Falls Short
NFT Verification has a place, but it wasn't designed for provenance.
Anyone can mint someone else's photo — the blockchain records the minter, not the creator. Stolen art is rampant in NFT marketplaces.
No connection to original capture — an NFT created after the fact has no cryptographic link to the moment the photo was taken.
Environmental and cost overhead — minting on proof-of-work chains has significant energy costs; even proof-of-stake chains charge gas fees.
Requires blockchain infrastructure — verification depends on chain availability, wallet software, and marketplace-specific standards.
How OP Is Different
OP uses the C2PA standard to embed cryptographic provenance directly in the file.
Provenance starts at creation — the C2PA manifest is embedded when the file is first signed, establishing origin from the source.
No blockchain required — verification uses standard cryptographic operations on the file itself. No wallet, no chain, no fees.
Embedded in the file — the provenance travels with the content, not in a separate ledger that can become disconnected.
Zero environmental overhead — signing and verification are lightweight cryptographic operations with negligible energy cost.
