🔐 9 crypto organizations launch the Quantum Alliance: ~6 M of $BTC (30.2% of the supply) already have an exposed public key. Not stealable today — but the risk is being prepared for now.

📌 The facts (Alliance + CoinDesk, Oct. 16, 2026)
• 9 organizations (Quantus, Midnight Foundation, Postquant Labs, Hacken, The Vault…) are creating an open standards body
• Goal: define what “quantum-ready” means and how to verify it
• ~6 M BTC exposed (30.2%); ~1.1 M of those attributed to Satoshi
• No current machine can break Bitcoin cryptography; some experts cite ~2028 as a possible window

🧠 How it works
When you sign a transaction, your public key remains on the ledger. A sufficiently powerful quantum computer (using Shor’s algorithm) could derive the private key from that public key. Today: impossible. Tomorrow: migration to plan for.

⚖️ The nuance
• This is NOT an imminent crash: theft isn’t possible with current hardware
• Freezing “vulnerable” BTC (an idea under debate, including Satoshi’s) = a debate about property rights, not a consensus
• The real cost = coordinating wallets, exchanges, miners — not just changing a formula

👤 Idrissa, a ride-hailing driver in Dakar, keeps a little BTC on an app. He doesn’t need to panic tonight. But understanding “exposed public key” helps him ignore scams like “sell your BTC before quantum computing arrives.”

✅ A distant threat ≠ an invented threat. Shared standards = less marketing, more evidence.

Are you already following the post-quantum migration… or waiting for your exchange to do it for you? 👇
