Abstract
For an encryption-protected decentralized and replicated blockchain file storage system maintained and managed by a channel of peers, the invention creates the additional levels of trust that are needed for peer voter authentication and transaction proposal endorsement. The invention effectively excludes hostile agents from influencing or impersonating legitimate voter peers through the mathematical strength of the K-of-N mechanism based on secret sharing with cryptographic hashing. In a further embodiment an extension to nested signatures is disclosed to enforce signing order.
