Canada's Post-Quantum Cryptography Deadline Is Here — What It Means for Bitcoin, Ethereum, and Solana
Canada just fired the starting gun on post-quantum cryptography. As of this month — April 2026 — every federal department must submit a migration plan to replace the encryption algorithms that protect government systems, banking infrastructure, and by extension, the blockchain networks that serve Canadian institutions. It is the first concrete sovereign deadline in any G7 nation, and it forces a question the crypto industry has been deferring: what happens to $308 billion in stablecoins, 6.5 million exposed BTC, and entire Layer-1 architectures built on cryptography that a future quantum computer could shatter?
The answer is no longer theoretical.
