The theoretical mechanism forces attackers to post matching collateral, risking total loss if an owner triggers a pre-committed cryptographic trap.
Key point 1 of 3
01
Cory Fields published a theoretical framework on Nov. 4 using "quantum landmines" to deter future quantum key recovery attacks .
Key point 2 of 3
02
Attackers targeting legacy addresses would be forced to deposit equal collateral into a timelock, which original owners can seize using pre-signed proofs .
Key point 3 of 3
03
Inactive or abandoned UTXOs would be protected by secondary auction models that destroy targeted coins and penalize malicious spenders .
Context
Shor's algorithm poses a theoretical long-term threat to older Bitcoin address formats that expose public keys on-chain.
Why it matters
If implemented, legacy coin holders would face collateral requirements and pre-commitment steps to safely migrate funds, while attackers would face substantial financial risks…
What to watch
Developer discussions on the Bitcoin development mailing list regarding consensus requirements and alternative post-quantum signature proposals.
