Abstract
Blockchain technology, while maturing, is still lacking features that would be considered indispensable in real-world business applications. In particular, the lack of transaction confidentiality in a public blockchain is a challenging problem. In this paper, the concept of aVirtual Private Blockchain (VPBC) is proposed as a mechanism to create a blockchain architecture with properties akin to those of a private blockchain, however leveraging existing public blockchain functionality. A VPBC can be set up between individuals or organisations, does not require any significant administrative maintenance, inherits all the functionality from the public blockchain, and achieves anonymity and transaction confidentiality with respect to any public blockchain node who does not belong to the VPBC. Building on this theoretical concept, it is then shown how the cryptographic technique of secret sharing can be used in order to implement a simple VPBC architecture. A proof-of-concept architecture has been created and early experiments indicatethat the creation of VPBCs for potential real-world applicationscenarios might be feasible.
