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
