Critics worry it contradicts Bitcoin's decentralized nature, yet some see anti-spam as necessary.
The proposal aims to delete "junk" UTXOs, raising ethical concerns about digital property rights.

QRAMP introduces a quarantine mode for legacy UTXOs to ensure post-quantum spendability with a two-phase commit and spend flow.
The mechanism avoids destination substitution by requiring on-chain commitment and matching spend phase proofs without historical lookups.
It proposes fee sponsorship for the commitment phase and seeks feedback on preventing destination substitution and consensus feasibility.
