Quantum Risk and Cryptographic Assumptions in 2025

Quantum computing is no longer a distant possibility.
It introduces emerging risk to the cryptographic assumptions underlying digital asset systems.

In 2025, developments from IBM, IonQ and other quantum research groups
have accelerated timelines, moving “Q-Day” from theoretical risk toward practical consideration.

Community Pulse: Perceived Quantum Risk

In our LinkedIn poll,

Quantum risk is perceived primarily through cryptographic break,
with less attention to migration inertia and system readiness.

This reflects a bias toward visible failure points,
while underestimating the slower constraints that determine whether systems can adapt.

How Quantum Computing Breaks Today’s Security

•  Shor’s Algorithm

Breaks RSA and ECC – the backbone of most blockchain and AI model signatures.
This affects the reliability of current digital signature schemes.

•  Grover’s Algorithm

Halves symmetric encryption strength (e.g., SHA-256).
What once took 2^256 guesses may soon take just 2^128.

•  Harvest Now, Decrypt Later

Attackers are storing encrypted data now to decrypt post-Q-Day.
Quantum doesn't need to break in today – it just needs to wait.

•  Systemic Risk Targets

The Q-Day threat extends to:

▪︎ Bitcoin wallets
▪︎ DeFi protocols
▪︎ AI intellectual property
▪︎ DAO governance systems

Systems dependent on cryptographic trust are exposed to varying degrees.

Post-Quantum Cryptography (PQC)

NIST Standards Finalized (2024–2025)

•  ML-KEM (Kyber) – for encryption
•  ML-DSA (Dilithium) – for digital signatures
•  SLH-DSA(SPHINCS+) – stateless hash-based
•  HQC – backup encryption scheme

Hybrid Cryptography: The Migration Strategy

•  NIST encourages migration via hybrid models (classical + PQC) to enable graceful fallback.
•  PQC introduces trade-offs including larger key sizes, but modern infra is increasingly optimized to support them.

Compliance Timelines

•  Migration timelines are emerging across financial infrastructure in major jurisdictions.

AI’s Dual Role: Accelerator & Defender

•  AI as Threat: AI may accelerate certain attack vectors and optimization processes.

•  AI as Defense: AI-driven PQC migration tools + anomaly detection + zk-resilience.

Example: zk-proof systems and decentralized AI model signatures (e.g. Bittensor)
are beginning to explore quantum-resilient approaches.

Industry Voices: What Experts Are Saying

“Quantum computing is not just a lab experiment anymore—it's a strategic risk. The sooner blockchains migrate to PQC, the better their chance of surviving the next decade.” — Dr. Dustin Moody, NIST PQC Lead

“Crypto’s threat model needs a 180° rethink in the face of quantum. ZK proofs, consensus design, and MEV markets could unravel unless we harden the crypto layer today.” — Zaki Manian, Co-Founder, Cosmos & Sommelier

"If your compliance plan doesn’t include quantum risk, it’s incomplete. Regulators are catching up faster than most teams realize." — Eva Chen, Digital Asset Regulatory Advisor, Singapore MAS

Action Map for Investors, Builders and Policymakers

Investors

  • Demand PQC Audits: Prioritize quantum readiness.

  • Watch Protocol Upgrades: Ethereum, Chainlink, QRL, Algorand.

Builders

  • Start PQC Migration: Adopt NIST-approved libraries (ML-KEM, ML-DSA, etc).

  • Design for Cryptographic Agility: Swap crypto primitives as standards evolve.

  • Join Community Pilots: Test hybrid models (zk + MPC + PQC).

Policymakers

  • Mandate Migration Deadlines: Report PQC-readiness by sector.

  • Fund Open R&D: Support tools, standards, and testing.

  • Coordinate Globally: Align timelines and signature protocols.

Scenario Framing: System Readiness vs Exposure

Scenario 1: Quantum-Ready

  • Lattice-based signatures protect smart contracts

  • Onchain provenance remains intact

  • zk systems and identity proofs remain verifiable

Scenario 2: Unprepared

  • Bitcoin wallets exposed post-decryption

  • DAO treasuries inaccessible

  • AI model provenance collapses

  • Cross-border payments lose cryptographic backing

Quick FAQ: What Readers Want to Know

•  How close are we to a practical quantum attack?

Estimated 5–10 years, but "harvest now, decrypt later" means risks are already live.

•  Can AI models be quantum-forged?

Model integrity mechanisms may be affected under quantum conditions.

•  Is PQC too slow or costly?

No. Lattice algorithms are faster than RSA. Key size is manageable. What’s missing is adoption.

What This Means for Cryptographic Trust

Quantum computing introduces uncertainty into the assumptions underlying cryptographic trust. 

As those assumptions become less reliable, trust shifts from
what systems are designed to guarantee → what remains reliable under changing conditions.
