摘要
This invention relates to a method of selectively authenticating a user of a blockchain with a smart contract deployed on said blockchain. The user has a hierarchical deterministic keys wallet comprising a path between the user's master private key and a private key specific to the smart contract, this path comprising a plurality of branches each carrying an index, the smart contract being univocally identified by one or several indices of branches followed by said path. The user can issue a transaction from an issuing account address, obtained by hashing the public key corresponding to said 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.
