A Novel Post-Quantum Approach: "Proof-Of-Decay" (Cryptographic Half-Life) for Unmigrated Dormant UTXOs
In briefProposed quantum defense: “Proof-of-Decay” for dormant unmigrated coins
SummaryThis Delving Bitcoin post proposes a middle path for old, exposed-key outputs that remain unmigrated to post-quantum addresses after a deadline: their balances would slowly decay on a block-height schedule, with decayed satoshis burned or sent to the miner reward pool. The author argues this avoids both a hard freeze and leaving coins fully exposed. The post asks developers whether such decay can be enforced at the consensus script level and whether it offers better game-theoretic protection.
