QSDM

QSDM (Quantum-Secure Dynamic Mesh ledger) is a post-quantum-secure ledger with a two-tier node model — CPU-only validators run the PoE + BFT consensus, and miners run an additive, Mesh3D-tied Proof-of-Work that mints the native coin, Cell (CELL). Two CPU miner binaries ship today (qsdmminer and the friendlier qsdmminer-console); a CUDA production miner is planned to ship after external security review.

Transaction signatures use ML-DSA-87 (NIST FIPS 204) — the standardised post-quantum replacement for classical Ed25519 / Ed448 — so transactions signed today remain unforgeable against cryptographically relevant quantum adversaries tomorrow.

Rebrand notice. This monorepo is migrating from the transitional name QSDM back to QSDM. Existing folder names (apps/qsdm-landing/, apps/qsdm-nvidia-ngc/) and configuration identifiers (qsdm.* configs, QSDM_* env vars, X-QSDM-* headers) continue to work during the deprecation window. See QSDM/docs/docs/REBRAND_NOTES.md for the full migration table.

Repository layout

Path	What it is
QSDM/	Ledger node — Go implementation (consensus, storage, ML-DSA-87 signatures, wallet/token API). This is the cryptocurrency / chain layer; native coin is Cell (CELL).
QSDM/docs/docs/	User-facing documentation: API reference, mining protocol, node-role split, quickstart guides, rebrand notes, roadmap, deployment guides.
apps/	Products and sidecars that use the node but are not required to run the core ledger.
apps/qsdm-landing/	Static marketing site served at qsdm.tech. (Folder name retained during the rebrand deprecation window.)
apps/qsdm-nvidia-ngc/	Optional NVIDIA NGC GPU attestation sidecar — opt-in, per-operator API policy, not a consensus rule. See QSDM/docs/docs/NVIDIA_LOCK_CONSENSUS_SCOPE.md.

• Release notes: CHANGELOG.md

New? The operator wiki is a 10-minute read that explicitly answers the three questions every new node operator asks: do I need an NVIDIA GPU, do I need a paid NGC plan, and do I have to sync to your VPS? Spoiler: no, no, and no — but NVIDIA is the first-class path today and api.qsdm.tech is the recommended bootstrap peer for Phase 4.

Trust surface (live reference node)

The reference deployment at https://api.qsdm.tech/ publishes two endpoints that make its own coverage legible:

• GET /api/v1/trust/attestations/summary — aggregate attested / total_public ratio across the validator set.
• GET /api/v1/trust/attestations/recent — list of recent peer attestations with coarse region/GPU-arch metadata only (no PII).

Consumed by the landing page and the dashboard. See QSDM/docs/docs/NVIDIA_LOCK_CONSENSUS_SCOPE.md for why NVIDIA-lock is a transparency signal, not a consensus rule.
