QSIG (Quantum Secure Interoperable Grid)
QSIG is a modular, AI-native security fabric for institutional and sovereign blockchain ecosystems. It coordinates audit, detection, response, custody, privacy, governance, network, and token security into a single composable grid, with support for 24+ chains and a PQC-aligned roadmap.
Role in the QIST Stack
Within QIST, QSIG functions as the multi-chain security and trust coordination layer:
- provides a reference model for unified security across heterogeneous L1/L2 environments
- enables research into sub-second detection and containment across multiple chains
- serves as a testbed for PQC integration across custody, transport, and attestation
Core Capabilities
- multi-chain coverage: unified enforcement and telemetry across 24 chains (EVM and non-EVM)
- eight infrastructure pillars: audit, detection, response, custody, privacy, governance, network, and token security
- AI-assisted defense: automated correlation and prioritization of incidents with target response under 5 seconds end-to-end
- PQC-aware roadmap: architecture explicitly designed to adopt Dilithium/Kyber across key custody, transport, and attestation surfaces
Research & Standards Focus
- formal models for cross-chain incident response SLAs
- PQC-ready custody and transport for institutional holdings
- techniques for adversarial simulation and red-teaming across 24-chain estates
- frameworks for governance-driven policy updates with cryptographic accountability
Collaboration Opportunities
QIST engages with:
- exchanges, custodians, and wallets integrating multi-chain security
- sovereign and institutional operators designing regulated chain infrastructure
- researchers working on PQC deployment strategies for blockchain systems
