Abstract
An authentication method for a user who has a hierarchical deterministic keys wallet including a path between the user's master private key and a private key specific to a smart contract, the path including a plurality of branches each carrying an index, the smart contract being univocally identified by one or several indices of branches followed by the path. The user can issue a transaction from an issuing account address, obtained by hashing the public key corresponding to the specific private key in an asymmetric cryptosystem, and can sign this transaction using the specific private key. The smart contract uses the signature to verify that the transaction was really issued from the issuing account address in question.
