Fault-tolerance

The article proposes a Raft variant using finite projective planes to form small, intersecting quorums (blocs) so progress can occur with fewer than a majority; it illustrates with a 7-node Fano-plane example and analyzes probabilistic trade-offs and open questions.

Facebook’s Gorilla is an in‑memory, write‑through time‑series DB that stores billions of series with sub‑millisecond reads, up to 40k queries/sec, and heavy compression to fit 26 hours of data in RAM, scaling horizontally across clusters.

Two quantum-computing bombshells (Caltech with lower-overhead fault-tolerance and Google with a smaller Shor’s-algorithm circuit) dramatically lower the qubit threshold to threaten current cryptography, accelerating the push to quantum-resistant schemes, particularly risking Bitcoin and 256-bit ECC.
