Abstract: A method of generating wallets for discrete blockchain networks comprising receiving a primary and a first secondary seeds, generating an enhanced hierarchical deterministic (HD) wallet, comprising deriving an enhanced parent public key and an enhanced parent private key from the primary seed, generating a first toughened HD wallet, comprising deriving a first toughened parent public and private key pair from the first secondary seed, deriving a first toughened primary child public/private key pair from a function including as inputs the first toughened parent public/private key pair, a first parent chain code, and the enhanced parent public key, and performing an identity registration and certification procedure for both the enhanced and the first toughened HD wallets. An identify of a user associated with each of the enhanced and the first toughened HD wallets is verifiable by an external blockchain network because of the identity registration and certification procedures.
