Abstract: Examples described herein relate to integrating a blockchain-enabled reader with a blockchain network over machine-to-machine communication protocol. A subscriber node may receive event data published by a publisher node. The event data may be communicated to the publisher node from a blockchain-enabled reader using a machine-to-machine communication protocol. The event data may be attested by the blockchain-enabled reader using a decentralized identity provisioned to the blockchain-enabled reader from the blockchain network. The decentralized identity of the blockchain-enabled reader may be verified. The event data may be submitted by the subscriber node to a distributed ledger upon successful verification of the decentralized identity of the blockchain-enabled reader.

Abstract: In some examples, a system is to receive, from a client device, a query comprising a representation of blockchain information of an entity associated with an electronic device that advertised the representation. The system is to further determine whether a client entity associated with the client device has a privilege to access response information that is responsive to the query, and in response to determining that the client entity has the privilege to access the response information, send, to a blockchain network, a request containing the blockchain information to obtain the response information.

Abstract: Implementations of the disclosure are directed to proving and creating on a distributed ledger a verifiable transaction record of a transaction between a user associated with user device and an agent associated with agent system, where the identities of the user and agent are hidden. Some implementations are directed to providing for hidden identity of claims where a distributed ledger identity of a user may be masked from an agent.

Abstract: Some implementations of the disclosure are directed to: receiving an encrypted message from an entity, the encrypted message including a request to determine if a claimant of a distributed attestation is a holder of the distributed attestation; decrypting the encrypted message; using at least a public key of the entity to determine whether the entity is authorized to obtain information about the distributed attestation; and if the entity is authorized to obtain information about the distributed attestation, transmitting a response message to the entity indicating if the claimant of the distributed attestation is the holder of the distributed attestation. Authorization of the entity to obtain information about the distributed attestation may be based on role based access control rights to obtain information about the distributed attestation.

Abstract: Implementations of the disclosure are directed to proving and creating on a distributed ledger a verifiable transaction record of a transaction between a user associated with user device and an agent associated with agent system, where the identities of the user and agent are hidden.
