Bitcoin developer Agustin Cruz has released a draft of a Bitcoin Improvement Proposal (BIP) called "Quantum Address Migration Protocol (QRAMP)" on the Bitcoin Dev mailing list, suggesting a hard fork to force users to migrate funds from old addresses that are vulnerable to quantum attacks to quantum resistant sub wallets. If the migration is not completed before the deadline, its Bitcoin will be unusable, essentially equivalent to destruction. At present, the proposal is still in the draft stage and has not yet been assigned a formal BIP number, nor has a consensus been reached within the community. （Protos） https://www.
