• Threshold Authorization Without Threshold Signatures: Signature-Agnostic MPC Custody

  July 9, 2026 · arXiv:2607.08226

  Dariia Porechna

  A dual-gate architecture that separates member authentication from threshold authorization, enabling post-quantum signature migration in MPC custody without redesigning the approval protocol.

• SILMARILS: Information-Theoretic and Quantum-Secure Designated-Verifier Signatures

  May 18, 2026 · arXiv:2605.03230

  Hassan Khodaiemehr, Khadijeh Bagheri, Chen Feng, Dariia Porechna

  A lightweight designated-verifier signature framework built on Shamir secret sharing, with security proofs in the random oracle and quantum random oracle models.

Reports

Each report maps named institutions, chains, and products to concrete PQ risk and new issuance decisions.

• Is Hyperledger Besu Quantum-Safe? An Institutional Post-Quantum Risk Assessment

  August 3, 2026

  No. Mainline Besu is not end-to-end post-quantum safe. Five coupled migration surfaces, DTCC and institutional exposure, privacy risk, TPS impact, and a practical remediation path.

• Your Chain Will Not Save You: Post-Quantum Institutional Risk Across Ethereum, Solana, and Canton

  July 1, 2026

  Why chain upgrades cannot fix immutable contracts, frozen standards, exposed public keys, ONCHAINID, ERC-2612, SPL Token, Canton privacy, and custody flows. EO 14412 and CBOM-ready analysis across $71T+ mapped exposure.

• The Post-Quantum Institutional MPC Custody Crisis 2026

  June 12, 2026

  15 institutional MPC custody providers protect $10T+ in digital assets, but none are post-quantum safe. Why hash-based PQ signatures break MPC custody and what institutions must do before NIST 2030.

• Post-Quantum Exposure Map 2026

  May 28, 2026

  The institutional map of post-quantum and privacy exposure across tokenized finance. 20+ named institutions, 30+ products, 11 chains. Legacy exposure is a migration problem. New issuance is a choice.

• Post-Quantum Signature Security Ranking 2026: Why SPHINCS+ Is the Only Institutional-Grade Choice

  May 18, 2026

  SPHINCS+ is the only NIST post-quantum signature with zero algebraic assumptions. Ranked against all 12 schemes for institutional deployment in 2026.

• Cryptographic Migration Debt: The Post-Quantum Risk Framework for Institutional Digital Asset Programmes

  May 2026

  Post-quantum exposure framework for boards, risk committees, and digital asset teams. Maps cryptographic migration debt across stablecoins, RWAs, custody, and settlement before NIST deprecation deadlines.

• Already Broken: The Post-Quantum Threat to Stablecoins, Tokenized Finance, and Privacy Chains

  March 2026

  27 institutions. Zero published post-quantum migration roadmaps. CISA 2027 federal agency deadline. Eight independent migration perimeters. The case that institutional blockchain infrastructure is already at risk.
