A quantum computer cracking Bitcoin's cryptography is the network's ultimate doomsday scenario. StarkWare researcher Avihu Levy just locked real BTC in storage the company says no quantum computer can open. Here's what makes it historic: - No fork, no upgrade needed - Runs on Bitcoin's existing rules - Live on mainnet, block 964,199 - Each spend costs $75 to $200 in GPU compute Over 6 MILLION BTC, 30% of supply, is still quantum-exposed, per Glassnode.
