Post-quantum cryptography transition accelerates across tech and finance

The transition to post-quantum cryptography (PQC) is accelerating across the technology and financial sectors as organizations prepare for the potential arrival of quantum computing capabilities. Industry experts warn that the first quantum-enabled attacks on blockchain networks might not appear as dramatic hacks, but rather as untraceable wallet compromises where attackers derive private keys directly from public on-chain data, leaving no traditional forensic evidence of a breach.

To address these vulnerabilities, technical developments are focusing on “crypto-agility”—the ability of systems to update cryptographic standards without requiring complete architectural overhauls. BTQ Technologies and Taiwan’s Industrial Technology Research Institute (ITRI) have successfully validated a Quantum Compute-in-Memory (QCIM) architecture. This hardware-based approach, tested in a TSMC 28-nm environment, accelerates NIST-standardized PQC algorithms while reducing latency and power consumption for IoT, automotive, and industrial systems.

Major players like Binance and security vendors like Palo Alto Networks are also implementing defensive measures. While quantum computing is not viewed as an immediate threat to current blockchains, the industry is moving toward coordinated adoption of PQC to prevent a “harvest now, decrypt later” scenario, where encrypted data is captured today to be decrypted once quantum technology matures.
