One example method includes receiving, by each node in a group of nodes that is organized in a logical hypercube topology, a message from a primary node that is a member of the group of nodes. When none of the nodes in the group of nodes are faulty, for each of 'n' prepare phases and ‘n’ commit phases of a communication protocol, transmitting, by each node to only a first respective pair node, a first group of one or more messages accumulated by the node, receiving, by each node from only a second respective pair node, a second group of one or more messages accumulated by the second respective pair node and, after the ‘n’ prepare phases and ‘n’ commit phases have been completed, each of the nodes has accumulated at least a minimum number of total messages to declare consensus.

Hypercube topology for byzantine fault tolerant solutions to reduce network communication overhead of PBFT-based protocols

Reducing network communication overhead in computing systems. In a computing system that uses messages to achieve consensus, a communication protocol is adapted to include row-wise and column-wise broadcast phases. This reduces communication complexity significantly compared to all-to-all communication protocols. In the event of faulty nodes, a post phase is introduced that allows additional communications in order to achieve consensus. Even when the post phase is required, the communication complexity is reduced compared to all-to-all based communication protocols.
