@primus_labs: the confidential infra for institutional onchain finance. FHE had a wall. Primus just showed how to climb it. Traditional FHE evaluated one simple gate at a time. A 64-bit operation meant thousands of gates, and thousands of bootstrappings. That was the wall. AutoHoG changes the shape of the problem. Primus's new FHE engine automatically designs custom gates that take multiple inputs and produce multiple outputs, then folds mergeable subcircuits into a single bootstrapping. On eight consumer NVIDIA RTX 5090s, hardware you can buy off the shelf, one 64-bit confidential transfer now takes about 90 milliseconds, throughput above 210 per second, bootstrapping around 5 milliseconds. Everything runs in integer arithmetic, so nodes produce byte-identical results. A confidential operation now finishes in under a tenth of a second on off-the-shelf hardware. The gap between FHE in theory and FHE that can actually run just got a lot smaller. AutoHoG. The wall just got lower.
