Adam Back (born July 1970) is a British cryptographer and crypto-hacker.
He is the inventor of hashcash, the proof-of-work system used by several anti-spam systems. A similar system is used in bitcoin.[1] Hashcash has also been used in a number of other protocols such as combating blog spam,[2] and defending against user namespace pollution.[3]
He implemented credlib,[4] a library that implements the credential systems of Stefan Brands and David Chaum.
He was the first to formalize the Non-Interactive Forward-Secrecy[5] security property for email and to observe that any Identity Based Encryption scheme can be used to provide Non-Interactive Forward Secrecy.
He is also known for pioneering the use of ultra-compact code with his 3-line RSA in Perl[6] signature file and non-exportable T-shirts[7] to protest the (now relaxed) United States cryptography export regulations.
Today he is CEO of Blockstream, a company that seeks to further the development of bitcoin and blockchain technology.[8]
He has a computer science Ph.D. from University of Exeter.
