Abstract: A system and a method of detection of an attack on a computer network including a plurality of nodes, the method including: associating the plurality of nodes with each other in a distributed ledger configuration; producing, by a requesting node of the plurality of nodes, a request to set a value of at least one key derivation parameter; performing a vote of confidence among a subset of the plurality of nodes regarding the validity of the request; and detecting an attack on at least one node of a plurality of nodes according to the vote of confidence.

Abstract: A system and a method of routing transactions between nodes of a computer network, by at least one processor. Embodiments of the method may include: receiving a destination feature vector (DFV) for at least one destination node of a plurality of destination nodes of the computer network; receiving a transaction request to route a transaction between a source node of the computer network and the at least one destination node; extracting from the transaction request one or more transaction parameters; and selecting a destination node from the plurality of destination nodes based on one or more of the transaction parameters and the DFV of the at least one destination node.
