This week we unpack why the “quantum threat” to crypto is no longer theoretical, and what it really means for Bitcoin, Ethereum, and the internet’s core security plumbing. We go past the hype into the math, the timelines, and the brutal migration and governance challenges facing decentralized networks.

• How Shor’s and Grover’s algorithms actually break today’s cryptography (and what they don’t break), plus why public-key systems like RSA and ECDSA are living on borrowed time.

• Why millions of BTC and over 65% of all ETH are already considered quantum‑vulnerable, including how Bitcoin’s address types and Ethereum’s account model expose long-term holders.

• The new NIST post‑quantum standards (ML‑KEM, ML‑DSA, SLH‑DSA), how lattice-based cryptography works, and the real-world engineering trade-offs of much larger keys and signatures for TLS, Web PKI, and on-chain migration.
