Ecosystem Patents¶
Soqucoin Labs Inc. has filed a portfolio of United States provisional patent applications covering the post-quantum techniques used across the ecosystem. Each is filed under 35 U.S.C. 111(b) and converts to a non-provisional within twelve months to maintain priority. Assignee: Soqucoin Labs Inc.
This page summarizes what each patent covers and why the technique is needed. The blockchain (Soqucoin L1) and bridge/wallet (SOQ-TEC) patents are detailed below; the compliance product (PQCAT) portfolio is summarized at the end with a pointer to its own site.
Soqucoin L1 (blockchain)¶
| Patent | Application | What it covers | Why it is needed |
|---|---|---|---|
| PAT (Practical Attestation Technique) | SOQ-P001, 64/022,954 | Commits a batch of ML-DSA signatures to a fixed 100-byte Merkle root that attests to them; the signatures themselves stay in witness data. | ML-DSA-44 signatures are 2,420 bytes each. PAT gives a constant-size on-chain commitment so per-block verification and footprint stay tractable. Active from genesis. |
| SoquObscura Confidential Transactions | SOQ-P010 (patent pending) | Amount-hiding transactions using ABDLOP lattice commitments with LNP22 range/balance proofs and LaBRADOR block-level aggregation. See SoquObscura. | Quantum-safe on-chain privacy without elliptic-curve cryptography. In development. |
| Lattice-BP++ Confidential Transactions | SOQ-P002, 64/023,515 | Ring-LWE commitments, lattice ring signatures, and Dilithium-compatible stealth addresses for opt-in privacy. | The foundational lattice-privacy techniques. Superseded in implementation by SoquObscura; the patent covers the underlying methods. |
| LatticeFold UTXO-Bound Batch Verification | SOQ-P004, 64/026,715 | Recursive lattice folding for near-constant-time block validation of post-quantum confidential transactions. | Scales verification as confidential-transaction volume grows. Research, reserved. |
| USDSOQ Consensus-Enforced Stablecoin | SOQ-P007, 64/047,929 | Native UTXO asset typing with threshold lattice authority and consensus-enforced mint, burn, and freeze operations. See USDSOQ. | A stablecoin whose supply invariant and controls are enforced by consensus on a quantum-safe chain. Active on stagenet. |
SOQ-TEC (bridge and wallet)¶
| Patent | Application | What it covers | Why it is needed |
|---|---|---|---|
| SoquShield Post-Quantum Mobile Wallet | SOQ-P003, 64/023,076 | ML-DSA-44 key generation and signing in a managed cross-platform runtime (Dart/Flutter) across iOS, Android, and web. | Makes post-quantum key management usable on consumer mobile devices from a single codebase. |
| XMSS-Lite Revolving Vault | SOQ-P005, 64/035,857 | Hash-based one-time-per-leaf custody that advances the signing leaf after each use. | A captured signing key is usable at most once, so a compromise does not drain the vault. See SOQ-TEC Gateway. |
| Quantum Express Cross-Chain Transfer | SOQ-P006, 64/035,873 | Optimistic cross-chain asset transfer with deferred post-quantum attestation and fraud-proof windows. | Reduces cross-chain confirmation latency without giving up post-quantum security. Design stage. |
PQCAT (compliance)¶
PQCAT is Soqucoin Labs' post-quantum cryptography compliance scanner, a separate product line. Its patents cover confidential compliance verification and cryptographic risk assessment:
- Confidential Compliance Engine (PQCAT-P001, 63/999,796): privacy-preserving compliance verification that proves an organization's post-quantum posture without disclosing its inventory.
- CCE with HNDL Risk Quantification (PQCAT-P001B, 64/023,449): a harvest-now-decrypt-later exposure scoring model layered on the compliance engine.
- Cloud-Native PQ Compliance Assessment (PQCAT-P010, 64/023,535): automated discovery and CNSA 2.0 scoring of cryptographic assets across cloud infrastructure.
- 2026 filings: Provenance Passport (64/122,032), Closed-Loop Remediation (64/122,047), Quantum X-Ray (64/122,137), and Harvest Clock (64/122,164).
