MAINNET PREVIEW · NIST FIPS 204 · NVIDIA-LOCKED

Post-quantum distributed trust,
NVIDIA GPU-attested by design.

QSDM is the Quantum-Secure Dynamic Mesh Ledger — a non-AI, hardware-agnostic electronic-cash and smart-contract fabric with a native coin, Cell (CELL). ML-DSA-87 post-quantum signatures, a dynamic 2D/3D mesh topology, Proof-of-Entanglement BFT consensus on CPU-only validators, and an additive NVIDIA-locked GPU mining layer that mints Cell from attested proofs.

Use QSDM

Three ways to use it today.

You don't need a server to start. A QSDM wallet runs in your browser; mining runs on a home NVIDIA GPU; a validator runs on a modest VPS. Each path is independent and production-usable on its own.

Wallet · Browser + CLI · Self-custody

Hold & sign with ML-DSA-87

The wallet at qsdm.tech/wallet.html generates a quantum-secure keypair, encrypts the private key with your passphrase, and lets you sign or verify any message — entirely in your browser. The companion qsdmcli wallet subcommand produces byte-identical keystores offline.

PBKDF2-HMAC-SHA-256 (600 000 iterations) + AES-256-GCM
Browser WASM module reuses cloudflare/circl — same code as the validator
No server keeps your key; nothing about a generated keypair leaves your tab

Miner · NVIDIA-locked · v2 only

Mine Cell on your GPU

Mining mints Cell (CELL) from attested NVIDIA proofs. The live mainnet runs v2 only — the v1 CPU path is rejected at consensus (ReasonBadVersion) and the v1 reference binary is no longer a public release artefact. Every accepted proof carries an NVIDIA attestation: nvidia-cc-v1 on Hopper / Blackwell datacenter GPUs with Confidential Compute, or nvidia-hmac-v1 on consumer RTX cards with a registered (node_id, gpu_uuid, hmac_key) tuple and a 10 CELL bond.

Hardware: any NVIDIA GPU you control + a host clock within 60 s of UTC
Tooling: qsdmminer-console --protocol=v2 — setup wizard, live panel, v2 client
On-chain: qsdmcli enroll bonds 10 CELL to your node_id
Funding caveat: v0.4.0 has no public faucet yet — new operators need a transfer from an existing CELL holder. The browser wallet's Send transaction tab (v0.4.0 Phase B) lets a holder sign a self-custody transfer entirely in-browser. See Appendix B.
Consumer rigs: an entry-level RTX 3050 (Ampere, sm_86) is enough — 4.06× over a 32-thread Xeon at n=4096 cells. Step-by-step setup: RTX 3050 cookbook.
Forged or replayed proofs are slashable (qsdm/slash/v1)
Halving emission, 90 M lifetime mining cap, 0 % pre-mine

Validator · CPU-only · VPS-class

Run a validator

Validators are the consensus tier. They run Proof-of-Entanglement + BFT on CPU-only VPS-class hardware and earn transaction fees. No GPU required. NVIDIA NGC attestation is available as an opt-in transparency signal, but it never gates consensus.

Why it matters

Post-quantum, hardware-bound, non-AI.

QSDM combines three properties that no other production ledger ships together: lattice-based signatures that survive a quantum adversary, GPU-anchored mining identity, and Proof-of-Entanglement consensus that doesn't burn watts to order transactions.

Post-quantum

Harvest-now-decrypt-later safe

ML-DSA-87 (NIST FIPS 204) keeps today's signatures verifiable after ECDSA and RSA are broken.

Hardware-bound

Sybil-resistant by silicon

Miners attest with an NVIDIA-locked proof bound to an enrolled operator key. Cloning costs real money — the bond burns on forgery.

Throughput

Mesh, not a chain

Cells can have multiple parents. Submeshes route by fee and geotag. No single block interval throttles the network.

Energy

No PoW in consensus

PoE uses cryptographic linkage, not brute hashing. The GPU mining layer is additive and can halt with zero impact on chain liveness.

Non-AI

Deterministic governance

Rule-based quarantines, snapshot voting, manual submesh templates. Auditable, reproducible, AI-free.

Open

libp2p + WASM + REST

GossipSub transport, WebAssembly contracts, REST + Prometheus endpoints. Nothing proprietary at the seams.

Operable

Single binary · two platforms

One Go binary. Ubuntu 24.04+ and Windows 10+ today; macOS in development. Systemd + Caddy deploy in under an hour.

Auditable

Metrics + signed releases

Prometheus scrape, audit reports with severity gates, cosign-signed binaries + container images, SLSA-attested npm tarball.

Live

Current release: v0.4.0 — ML-DSA-87 consensus, v2 NVIDIA-locked mining with active forged-attestation and double-mining slashers, qsdm-sdk@0.3.0 on npm, GHCR container images at :0.4.0, and the self-custody wallet now includes a Send transaction tab that signs a fully client-side ML-DSA-87 envelope and POSTs it to the new /api/v1/wallet/submit-signed endpoint — the sender's private key never leaves the browser. Detail in RELEASE_NOTES_v0.3.0.md and on the GitHub releases page.

Under the hood

How the pieces fit.

A single Go binary terminates consensus, storage, and the public API. Caddy fronts TLS; libp2p is the peer transport. The browser wallet talks to the same REST surface as the SDKs.
