Proofivy

Proofivy is an infrastructure platform that provides cryptographic proof of ownership for digital files and enables web publishers to monetize artificial intelligence scrapers. Instead of uploading entire raw files to public infrastructure, the service anchors SHA-256 cryptographic hashes directly to the Ethereum blockchain, establishing an immutable timestamp for the committed fingerprint without exposing sensitive underlying content.

How provenance and x402 monetization work

Proofivy functions through two core architectures: Digital Seals and the x402 pay-per-article protocol. For provenance, a user's client calculates a content identifier using SHA-256 and commits the hash onchain through smart contracts. When using the native iOS application, commits are signed with the user's key and submitted via an address managed by Proofivy. Through its dedicated smart contract, creators can convert timestamped proof commits into tradeable NFTs to transfer digital rights. For publishers, Proofivy runs x402 server infrastructure that identifies automated scrapers and requests micropayments in Base USDC, keeping human reader access intact while settling machine transactions onchain in seconds.

Pricing and contract operations

Public interaction with the Proofivy smart contracts requires payment in ETH. Standard public commits cost 0.001 ETH each, while public onchain text messages cost 0.002 ETH. The NFT contract allows users to convert established proofs into NFTs for free, excluding the necessary network gas fees. Organizations and enterprises can organize under Guilds, which waive per-operation transaction fees for validated team members through subscription plans and custom onboarding.

Adoption and development milestones

The proofivy.com domain was registered in August 2021. The platform released its first mobile version on the Apple App Store in March 2023, joined the Content Authenticity Initiative in June 2023, and moved commit anchoring to Ethereum mainnet the same month. More than 10,000 works have been secured across creative and scientific fields, including work by The Lab for Germinal Center Biology. CryptoSlate deployed Proofivy's x402 infrastructure as the first production implementation of pay-per-article charging for AI access.

Operational risks and architectural trade-offs

Proofivy handles data verification rather than decentralized storage, meaning users remain entirely responsible for storing original files matching the registered hashes. Mobile submissions route through a Proofivy-operated Ethereum address, introducing a custodial execution layer between the mobile user and the network.
