Abstract: An example operation may include one or more of generating, by a data management node, a profile token based on a data profile of a data provider (DP) node, receiving, by the data management node, a transaction request from a service provider (SP) node to access data from the DP node over a blockchain, acquiring, by the data management node, consent of the SP node based on the profile token, generating, by the data management node, a consent token based the consent of the SP node, and allowing access to data of the DP node by the SP node based on a verification of the consent token.

Abstract: An example operation may include one or more of connecting, by a participating node, to a blockchain configured to store user assets, receiving, by the participating node, login data from a user, receiving, by the participating node, an asset transfer request from the user identified by the login data, the asset transfer request including identification data of an asset recipient, confirming, by the participating node, that the user is an owner of the asset based on a previous asset transfer transaction associated with the user, verifying, by the participating node, integrity and validity of the asset based on blockchain records, determining, by the participating node, that the asset recipient is a registered user of the blockchain, in response to the determining, by the participating node, that the asset recipient is the registered user of the blockchain, encrypting, by the participating node, an asset transfer transaction by a public key associated with a private key of an auditor; and providing, by the par
