Patent attributes
Systems and methods for cryptologic blockchain interoperability are provided. A furnisher participant of a furnisher DLT network may receive a request to export or share token data stored on a furnisher blockchain that stores the token data based on a furnisher DLT. The furnisher participant may transmit, to a plurality of validator participants of the furnisher DLT network, a consensus request to certify the token data is stored on a furnisher blockchain. The furnisher participant may receive certifications that the token data is stored on the furnisher blockchain. The certifications may include digital signatures respectively signed by the validator participants. The furnisher participant may generate a multi-signature certification message. The furnisher participant may communicate the multi-signature certification message to the data receiver. The data receiver may verify the digital signatures based on public keys of the validator participants of the furnisher DLT network.
