Raft Consensus with a Minority of Nodes

A researcher proposes a modification to the Raft consensus protocol that allows progress with fewer than a majority of active nodes under certain constraints, using mathematics from finite projective planes—the same mathematical structure underlying the card game Spot It! The key insight is that just as any two cards in Spot It! share exactly one symbol, any two sets of nodes in this modified system share at least one node, maintaining consistency while reducing the quorum requirement. This approach demonstrates how elegant combinatorial mathematics can solve practical distributed systems problems.
