Publication number: 20240022429Abstract: In validating a new validator for a proof-of-origin blockchain, an announce message is received including: a unique tag (T) uniquely identifying one fixed communication line of a subscriber of a fixed communication operator; a peer identifier (peer@) of the new validator; an identifier of an authorised signer, and a cryptographic signature (S2) of the authorised signer over at least the unique tag (T) and the peer identifier (peer@); validity of the announce message is verified, including checking from the PoO blockchain that the authorised signer is registered there as an authorised signer and checking the cryptographic signature (S2) of the authorised signer in the announce message. If each checking of the verifying is positive, then accepting the new validator for the PoO blockchain and mapping in the PoO blockchain the unique tag with at least the peer identifier, otherwise refusing the new validator.Type: ApplicationFiled: June 28, 2023Publication date: January 18, 2024Inventors: Bart THEETEN, Michael TIMMERS
