The proposals aim to protect dormant coins vulnerable to quantum attackers by introducing collateral and auction-based defenses rather than relying solely on post-quantum signature upgrades. The approach matters because a large share of Bitcoin's supply sits in old addresses whose public keys could eventually be exposed to quantum decryption. Details of how each mechanism would be enforced at the protocol level remain the key item to watch as discussion develops.
