Ring the Alarm, Get Paid: BitMEX Proposes Quantum Canary Fund as BTC Freeze Alternative

BitMEX Research has dropped a hot take on how to handle the quantum computing apocalypse—and surprisingly, it doesn't involve politely asking Satoshi's coins to stay put. They've pitched a "canary fund" as a less controversial alternative to freezing quantum-vulnerable dormant Bitcoin.

The proposal, dubbed a "canary watch state," would only trigger a full freeze if a quantum computer capable of stealing BTC actually exists and makes its move. Think of it as a very expensive tripwire rather than a blanket "no touchy" sign.

Here's the twist: the system creates a special BTC address using a "Nothing-Up-My-Sleeve Number" (NUMS). The private key is unknown, but it's a valid address that theoretically could be spent by a powerful enough quantum computer. Users can donate BTC to this address as a bounty—essentially paying any quantum-capable actor to "ring the alarm" by spending from it.

Only when someone spends from the canary address does the freeze automatically activate, proving the quantum threat is real. It's basically a honeypot, but for mathematicians with supercomputers. Come at the king, you better not miss.

This approach stands in contrast to BIP-361, which proposed unconditionally freezing dormant, quantum-vulnerable Bitcoin. That proposal drew significant community backlash, with critics calling it "authoritarian" and "confiscatory." Twitter did what Twitter does, and the discourse went exactly how you'd expect.

Under BitMEX's canary watch state, old coins could still be spent—provided malicious quantum actors don't touch the canary fund. Investors can use multisig and withdraw anytime. Your coins, your keys, your quantum drama.

"While this approach adds complexity and risk, given how controversial any coin freeze is, mitigating the impact using this type of system may be worth consideration," BitMEX noted. Translation: we know this is weird, but frozen coins are weirder.

BIP-361 co-author Jameson Lopp clarified his proposal was merely a "rough idea for a contingency plan." He told Cointelegraph it was a "rough sketch" addressing a potential "looming circulating supply shock" if quantum computing advances to the point that a post-quantum signature scheme achieves Bitcoin consensus. In other words: calm down, it was a whiteboard exercise.

In short: nobody knows if quantum-secure cryptography will even work. But at least someone's brainstorming. And if quantum computers do crack Bitcoin's keys, at least we won't have to wonder who's behind it—we'll just watch the canary get eaten.
