Morning Minute: Mark Cuban Sells His Bitcoin

The problem they’re solving is the “Satoshi problem” that has haunted every quantum defense proposal so far. Bitcoin’s roughly 6.9 million coins in addresses with exposed public keys are directly vulnerable to any quantum computer powerful enough to run Shor’s algorithm against secp256k1 elliptic curve cryptography. BIP-361, authored by Jameson Lopp, proposed freezing those coins if they don’t migrate to quantum, but Cardano founder Charles Hoskinson pointed out a fatal flaw: “1.7 million coins can’t do that. It’s not possible. 1.1 million of which belong to Satoshi.” If Satoshi is dead or the keys are lost, there’s no way to migrate voluntarily.

AmericanFortress’s approach is different. Rather than requiring migration or imposing a freeze, their proposal uses a soft fork to create a protected dormancy state, essentially putting a quantum-resistant cryptographic lock around vulnerable addresses without requiring the owner to move the coins or prove control. The system layers multiple post-quantum signature schemes to prevent any quantum attacker from exploiting exposed public keys.

The proposal is in early-stage peer review and has not been submitted as a formal BIP. The parallel PACTs proposal from Paradigm researcher Dan Robinson offers another path, letting holders timestamp cryptographic proofs of ownership today and later unlock coins via quantum-resistant STARK proofs if the network freezes vulnerable addresses.
