Quantum Alert: China's Commercial Quantum Computer and the Urgency for Post-Quantum Cryptography
Quantum Decryption will render blockchain useless and Decryptable
With Quantum Computing，it is a threat to Human Digital Economy which is base on Secured Transactions
Critical Alert: December 2025
China has launched Hanyuan No. 1, the world's first commercially available neutral-atom quantum computer, with over 100 qubits and real-world sales already underway (including exports). This milestone accelerates the global quantum race and underscores the growing threat to current cryptographic systems.
While blockchains are NOT at immediate risk of decryption today, the clock is ticking faster toward "Q-Day" — the point where large-scale quantum computers could break ECC and RSA encryption used in Bitcoin, Ethereum, and beyond.

The PQC Era Is Here — Migration Is Urgent
The Post-Quantum Cryptography (PQC) transition is no longer optional:
NIST standards (ML-KEM, ML-DSA, SLH-DSA) finalized in 2024.
Major adoption in 2025: Cloudflare (>50% traffic hybrid PQC), OpenSSL defaults, Apple ecosystems, browsers.
Governments and enterprises mandating PQC for critical infrastructure.
HARVEST NOW, DECRYPT LATER THREAT
TRUST NOW, FORGE LATER THREAT
| Threat Level | Current Status | Timeline to Worry |
|---|---|---|
| Quantum Hardware | 100+ qubit commercial systems (China's Hanyuan No. 1) | Immediate accessibility for research/optimization |
| Blockchain Decryption | Not possible yet (needs millions of logical qubits) | 2030s–2040s estimated for full breaks |
| Harvest-Now-Decrypt-Later | Active threat today | Migrate ASAP |
| PQC Adoption | Rapidly accelerating | Now — to avoid future crises |
Action Steps
Assess exposure: Avoid address reuse in crypto wallets.
Migrate to PQC: Implement hybrid cryptography in systems.
Monitor upgrades: Watch Ethereum/Bitcoin proposals for quantum-resistant signatures.
Stay informed: Follow NIST, Cloudflare, and quantum research updates.
The future is quantum-secure — but only if we act now.
Working Together
CREATE A COMMITTEE THAT HELP EACH OTHER TO BE PQC ENABLED.
