What is real in 2026
- Device: two terminals, history-dependent resistance (LTP / LTD).
- Update rule at the device: pair STDP or triplet STDP. No backprop required.
- Prototypes named in literature: Cs3Bi2Br9/NiO, 2D InSe (fJ-class reports), photon-controlled memristors, halide perovskite / BaTiO3 variants.
- Nearby chips (not claimed as Dualis): BrainChip AKD1500 event neuromorphic; Intel Loihi 2 / IBM NorthPole in-memory compute.
DualisCapax does not manufacture or ship memristive synapses. This page is a software sketch.
Software sketch of a resistance update
Not hardware. A slider sends a pre/post spike pair. Conductance G moves toward LTP if the post spike is after the pre spike, LTD if before. Units are fake.

Ed25519 vs HMAC (tickets)
HMAC-SHA256 is a shared secret. Anyone who has the secret can mint a ticket. That is local IPC only.
Ed25519 is asymmetric: a private key signs RFC 8785 canonical JSON; a public key verifies. Sovereign / production tickets must not treat HMAC as equivalent.
Ice passkeys on this site are WebAuthn on the phone. They are not memristors and they are not a factory root key.
