[Wu Blockchain News] Bitcoin Core Developer Proposes Collateral and Auction Mechanisms to Deter Quantum Theft

Under the framework, spending old coins once quantum attacks become feasible would require equivalent BTC collateral, with Quantum Landmines letting owners who pre-register cryptographic proofs protect funds and claim an attacker's collateral. The auction designs would impose financial risk on attackers even when original private keys are presumed lost, letting third parties compete for that collateral; in the Staked Auction variant, vulnerable BTC would be burned rather than returned to its owner. The proposals remain conceptual, with implementation details still to be worked out.
