A new proposal from BitMEX Research is reshaping how the crypto industry could respond to a future quantum computing threat, offering a “canary fund” mechanism instead of immediately freezing vulnerable coins.
The idea arrives at a moment when the Bitcoin community is actively debating how to defend against quantum risks—highlighting a deeper tension between security and decentralization.
A Different Approach to a Growing Concern
The proposal introduces a conditional system rather than a preemptive one. Instead of locking potentially vulnerable dormant coins in advance, BitMEX suggests waiting until a quantum threat is proven to exist.
At the center of the model is a special address built using a “Nothing-Up-My-Sleeve Number” (NUMS), a cryptographic construct where no one knows the private key.
If a sufficiently powerful quantum computer ever manages to break Bitcoin’s cryptography, this address becomes the test case.

How the Canary Fund Would Work
Participants can send Bitcoin to this address as a bounty. The incentive is simple: if a quantum-capable actor can spend from it, they effectively prove the threat is real.
That single event would act as a trigger. Only then would a broader defensive mechanism—such as freezing vulnerable coins—activate automatically.
Until that point, the system remains in what BitMEX calls a “canary watch state,” allowing normal network activity without disruption.
A Response to Controversy Around BIP-361
The proposal is a direct response to the recently discussed BIP-361, a draft idea suggesting that dormant Bitcoin susceptible to quantum attacks should be frozen preemptively.
That concept sparked backlash across the community, with critics labeling it “authoritarian” and “confiscatory,” arguing it could undermine Bitcoin’s core principles of ownership and immutability.
By contrast, BitMEX’s approach attempts to balance caution with restraint—intervening only when evidence justifies it.
Built-In Flexibility and Safeguards
The canary fund model includes mechanisms designed to reduce unintended consequences. Users contributing funds can withdraw using multisignature setups, maintaining control over their assets.
It also introduces a safety window beyond the five-year timeline proposed in BIP-361, allowing certain transactions to proceed while temporarily restricting outputs.
This layered structure reflects an effort to manage risk without imposing blanket restrictions on the network.
Even Its Critics Call BIP-361 a Placeholder
Notably, Jameson Lopp, co-author of BIP-361, has described his own proposal as a “rough idea for a contingency plan” rather than a finalized roadmap.
He acknowledged community discomfort, stating he does not favor the approach himself but views it as preferable to inaction if quantum capabilities advance rapidly.
The debate underscores how early-stage the industry still is in planning for post-quantum scenarios.
Market Reaction: Minimal, But the Stakes Are Long-Term
Despite the significance of the discussion, market reaction has remained muted. Quantum risk is still perceived as a future problem, not an immediate catalyst for price movement.
However, the implications are structural. Decisions made now could shape how Bitcoin evolves under extreme technological shifts.
Investor Psychology: Security vs. Principle
The divide reflects a deeper psychological split within the crypto community.
One side prioritizes proactive defense, even if it means altering long-standing rules. The other views such changes as a slippery slope that could weaken Bitcoin’s foundational guarantees.
BitMEX’s proposal sits between these positions, attempting to delay irreversible decisions until evidence forces action.
What Comes Next in the Quantum Debate
The conversation around Bitcoin quantum security is likely to intensify as research progresses and standards evolve globally.
Future proposals may refine these ideas further, combining elements of detection, incentives, and conditional safeguards.
What remains clear is that the industry is shifting from theoretical discussions toward practical contingency planning.
BitMEX’s canary fund proposal highlights a critical phase in Bitcoin’s evolution, where preparing for unlikely but high-impact risks must be balanced against preserving core principles. The outcome of this debate will influence not just security strategy, but the philosophy underpinning the network itself.
