SECURE TRANSACTIONAL SYSTEM IN A P2P ARCHITECTURE

摘要

The invention relates to a secure P2P transactional system comprising a set of nodes (WN) communicating by messages (WM), each message comprising data to be processed by a program (WP) and the hash of the program to be used at the destination node on the input data contained in this message, wherein, upon receiving a message and by using the hash contained in this message, each node is capable of causing the execution of the program to be used on the input data contained in said received message, said program generating an output message containing output data generated by the program and the hash of the program. The system is characterized in that at least certain programs are capable of being executed in a zero-knowledge proof mode (ZKP) and of including in output messages a zero-knowledge proof information for verification by the destination node.
