  • Chuen (ed) 20156 (†855 p.21): … Bitcoin … uses an asymmetrical algorithm that generates two separate but asymmetrically linked keys: a public key and a private key. The keys are asymmetrical in the sense that the public key is derived from the private key but it is computationally impossible to obtain a private key from a public key. … The private key, on the other hand, must be kept secret and safely.
