Have you ever taken a photo of your passport, diploma or any other important document? One out of four manages their personal documents already digitally. By doing so, all security features are rendered void and verification is a hassle.

sproof provides an easy to use API that can be integrated in any application for digitally signing important documents.

Decentralized

sproof is completely decentralized and every entity manages their documents themselves. sproof does not act as an intermediary and thus does not need to be trusted.

Scalable

sproof is open and the source code can be verified by everyone. The sproof protocol is publicly available and sproof is documented in peer-reviewed scientific publications.

Transparent

sproof is transparent and all issued documents are publicly verifiable. The history of all digitally signed documents is visible to everyone in order to prevent fraud.

sproof allows you to issue important documents or register data in industrial applications with an unique signature and a timestamp. A verifier can easily check the integrity and authenticity of that data without the need of a single trusted third party.
