About Proxae Expand
Proxae provides a service for creators and professionals to establish verifiable, permanent proof of creation for their digital assets. It achieves this by anchoring cryptographic fingerprints of files and web pages in the Bitcoin blockchain.
This method offers a trustless alternative to traditional notarization, leveraging the inherent immutability of Bitcoin's ledger. The platform calculates fingerprints client-side, ensuring user privacy and independent verification.
With OpenTimestamps integration and shareable proof links, users can easily demonstrate prior existence of their work. An optional Pro tier adds eIDAS qualified certificates for enhanced legal standing, catering to those who require stronger evidentiary value.
