Quantum Threat Alliance Forms: 6.4 Million Bitcoin's Keys Already Exposed, and Experts Can't Even Agree on When the Threat Arrives
Bitcoin's greatest "nobody can change it" achievement — fixed supply, unbreakable keys — is being eyed by something that doesn't exist yet: a quantum computer.
Three key facts
Nine crypto companies jointly launched the "Quantum Alliance" to develop common quantum-resistant security standards for Bitcoin, Ethereum, and other blockchains. According to CoinDesk, the Alliance's concern is that future quantum computers could reverse-engineer a wallet's public key to uncover its private key and steal funds. The Alliance estimates that about 6.4 million bitcoin (30.2% of the supply) already have their public keys exposed, including roughly 1.1 million attributed to Satoshi Nakamoto. The Alliance also clarifies: no existing quantum computer is powerful enough to steal coins this way today.
Experts disagree sharply on "when it happens." The Vault's chief revenue officer Bryn Bennett said: "Nobody knows the date, but the estimates keep falling, and the risk is one we can already plan for." Postquant Labs CTO Richard Carback went further, calling 2028 a "realistic" date for a machine capable of breaking today's cryptography. Recent research has cut the estimated computing power needed to attack bitcoin and Ethereum by half.
The hardest part isn't the tech — it's "should we touch those coins." If Satoshi's 1.1 million bitcoin are actually stolen by a quantum attack, the community faces an awkward choice: whether to freeze, move, or place the vulnerable bitcoin in a trust. The report notes such proposals have raised concerns about "property rights" and "network neutrality," and any security upgrade would require broad coordination across the entire Bitcoin ecosystem.
Wang Dou's Take
Start with the absurdity: a ledger famed for "fixed supply, immutability" now has as its core debate topic — whether to forcibly modify it to save coins that can't be modified. For a decade, "code is law" was shouted from the rooftops; now, the moment a quantum threat is raised, the first proposals on the table are "freeze, move, place in a trust" — all human intervention. So-called immutability, once it involves your own people's money, becomes "negotiable."
The second interesting thing is the industry's collective silence on timing. An alliance seriously preparing to counter a threat can't even agree on which year it arrives — optimists say 2028, cautious ones say 2035 or later, a gap of seven or eight years. What does that mean in engineering terms? It means you can neither rebuild the entire network now (too early, too costly) nor do nothing (in case 2028 is real). So everyone chose the least troublesome path: form an alliance, publish standards, make a good show of posture. As for the real migration, wait until everyone finishes arguing.
Finally, Satoshi's 1.1 million coins. Untouched for over a decade, treated by countless people as "the anchor of faith." The current situation is this: whoever builds the first usable quantum computer can likely take them — possibly "with the blessing of whichever national government." In other words, bitcoin's most sacred asset may ultimately belong neither to Satoshi nor to the community, but to whoever builds the machine first and happens to be tolerated by some government. That picture is more ironic than any hacker movie.
