Abstract
A client computer system implements a cryptocurrency wallet using derived cryptographic keys generated from an implicit certificate. The client computer system uses a root key pair that includes a root public key and a root private key to produce the implicit certificate. The implicit certificate is provided to other entities which generate derived public keys from the implicit certificate. In an embodiment, the client computer system encodes an identifier and additional information into the implicit certificate. In an embodiment, entities may derive one or more public keys from the implicit certificate, and the client computer system may derive corresponding private keys from the implicit certificate and the root key pair. In an embodiment, the client computer system generates a tree or derived key pairs that may be used to delegate portions of the cryptocurrency wallet to other computer systems.
