According to BitMEX Research, the proposal under discussion can be abused via a five-step process that encrypts objectionable content into a block, completes a large on-chain payment to receive service, waits any duration, then publishes the decryption key and, if a reorg occurs, rebroadcasts the large payment with a higher fee to self, enabling a double spend, source: BitMEX Research on X, Oct 27, 2025. BitMEX Research states the design encourages both double-spend attacks and the propagation of objectionable content while giving attackers control over transaction timing and sequencing, source: BitMEX Research on X, Oct 27, 2025. The scenario explicitly targets large BTC payments post-service delivery, underscoring direct settlement risk if such a mechanism were adopted, source: BitMEX Research on X, Oct 27, 2025.
