In general Verisart seeks engineers interested in applying cryptography at real world problems. Our problem lies within the art market as we address the problem of proving provenance for artworks and building evidence based certificates of authenticity. We recognize that cryptography is not a magic bullet. We want to use it intelligently to provide evidence where possible for people to interpret, like the web of trust. We’re looking for people who understand how to apply cryptography to problems. While understanding the mathematical backgrounds to cryptography is great, it’s not essential if you understand how the cryptographic primitives like hashing and message signing work together to solve real problems. We value passion and hard work when tackling challenges and above all else although an interest in arts and collectibles is helpful.
