Abstract
A method and a system for multi-factor authentication for blockchain services are proposed. The method comprises holding, by a server, an account of an end-user, the account being identifiable via an accountID; associating the accountID with a clientAddr by executing a pairing process; establishing, by the end-user, using a software application, an approval status for a multi-factor service in the server; in response to said established approval status, calling, by the server, a changeStatus function of a multi-factor provider smart contract operating in at least one blockchain, the changeStatus function including the established multi-factor approval status, the clientAddr, and a certificate termed ownerAddr; modifying, by the provider, the established approval status in the blockchain; delivering, by the provider, a notification to the end-user via the server when the established approval status is modified in the blockchain; and retrieving, by a smart contract developer the established approval status from the provider.
