Proxae

About

Proxae is a service that allows users to timestamp texts, ideas, and files on the Bitcoin blockchain, providing an immutable proof of existence. By computing a SHA-256 fingerprint locally and anchoring it to Bitcoin, users can prove they had a certain idea or document at a specific point in time without revealing the content itself. The process is private, as only the fingerprint is transmitted, and the proof is verifiable independently without requiring trust in Proxae. Targeted at creators, freelancers, developers, and authors, Proxae solves the problem of proving prior existence in cases of intellectual property disputes, plagiarism, or idea theft. It offers a free tier with unlimited certifications and a Pro tier with eIDAS-qualified PDF certificates for legal proceedings. The service is designed to be a permanent, complementary alternative to traditional methods like the Soleau envelope or bailiff reports. Proxae also provides an interactive demo and real-world scenarios showing how its proofs have been used to resolve disputes amicably or in court. The platform supports multiple languages and allows users to verify certificates without an account.
