Alan Turing (1912-54), British mathematician. Turing was educated at Cambridge and Princeton. In 1937 he described a theoretical computer (a Turing machine) in rigorous mathematical terms, formalising the previously vague concept of computability. During the Second World War he worked as a code breaker at Bletchley Park, Britain's codebreaking centre. In 1939-40 Turing and Cambridge mathematician, Gordon Welchman, designed the British Bombe, which could break any Enigma-enciphered message. In later years he worked on Artificial Intelligence, devising the Turing test to decide whether a computer can be thought of as truly 'intelligent'. Turing committed suicide when prosecuted for his homosexuality, at that time a criminal offence.

This design is inspired by medieval heraldry. It depicts a griffin, gryphon or griffon, a mythical creature with the body, tail, and legs of a lion while the head and wings are those of an eagle. The griffin was a divine guardian, but here he symbolises the guardian of the blockchain. Because a blockchain’s security relies on cryptographic hashing functions, the mythical creature is called the "cryptohash griffin”. The design is very suitable for white backgrounds. A design with slightly brighter text is also available for black backgrounds. Use this design for yourself or anyone interested in blockchain, decentralisation and cryptocurrency.
