Rust Post-Quantum cryptography

Auditable & minimal JS implementation of public-key post-quantum cryptography

Assembly super-optimization via constraint solving

Post-quantum QUIC-based VPN

A pure python implementation of ML-KEM (FIPS 203) and CRYSTALS-Kyber

Python 3 bindings for liboqs

Semantic SBOM/CBOM diff, quality scoring, and TUI analysis tool for CycloneDX/SPDX — covering component changes, dependency shifts, license conflicts, vulnerabilities, cryptographic inventory grading, and PQC compliance (CNSA 2.0, NIST IR 8547).

The SPHINCS+ reference code, accompanying the submission to NIST's Post-Quantum Cryptography project

Secure, fast, and portable C90 implementation of ML-KEM / FIPS 203

Official Rust client for Quantova, the post-quantum Layer-1 — built by Quantova alongside qweb3.js and qweb3.py. Connect, derive Q addresses, use the QVM and QNS, and sign with post-quantum keys. Quantova's own implementation, not a fork or copy.

A python implementation of the signature scheme Falcon

Post-quantum Web3 client SDK for the Quantova Layer-1 blockchain. JavaScript/TypeScript, shipped as CommonJS + ESM with type definitions. Falcon/Dilithium/SPHINCS+ signing, the q_* JSON-RPC namespace, QVM contracts (Solidity ABI), QNS .q names, fee/gas oracle, batch requests, real-time event hooks, REST client, and a qweb3-cli.

Open-source core banking platform — 61 DDD domains with event sourcing, CQRS, and a schema-first GraphQL API. Multi-asset accounts, exchange, lending, compliance, x402/MPP machine payments, and a non-custodial wallet backend. Laravel 12 / PHP 8.4. Reference implementation: the GCU basket currency.
