MULTI-INSTANCE ARCHITECTURE SUPPORTING TRUSTED BLOCKCHAIN-BASED NETWORK

Abstract:

An example embodiment performed by a scoped software application executable on a computing device of a computational instance within a trust group of computational instances of a remote network management platform may involve obtaining a representation of one or more transactions involving the computational instance. The embodiment may also involve encrypting the representation, using a pre-shared key to which at least some computational instances within the trust group have access. The embodiment may also involve placing the encrypted representation into a data block that also includes: (i) a first output generated by applying a hash function to content from a previous data block of a blockchain-based transaction ledger, and (ii) a second output generated by applying the hash function to the encrypted representation and the first output. The embodiment may also involve distributing copies of the data block to blockchain-based transaction ledgers within each computational instance of the trust group.
