Computer-implemented system and method for fault-resistant multi-node communication

A computer-implemented method of fault-resistant multi-node communication, the communication having a plurality of participating nodes, each node having its own public key and private key forming a public-private key pair, each node having a respective output address to which the communication is to assign tokens, the method comprising:

• encrypting, by a node of the plurality of participating nodes, a first output address using a first public key to obtain an encrypted first output address, the first output address being the respective output address of the node, the first public key being the public key of the node;
• adding the encrypted first output address to a set of encrypted output addresses;
• shuffling the order of encrypted output addresses in the set;
• sending the set to a next node;
• receiving a further shuffled set of addresses from another of the participating nodes, the further shuffled set of addresses including the encrypted first output address;
• replacing the encrypted first output address in the further shuffled set of addresses with the first output address;
• and
• forwarding the further shuffled set of addresses containing the first output address to a subsequent node.
