Changpeng Zhao Floats Freezing Satoshi's Bitcoin to Blunt a Future Quantum Theft

Changpeng Zhao, the founder and former chief executive of Binance, has proposed freezing up to one million Bitcoin linked to the pseudonymous creator Satoshi Nakamoto if those coins remain unmoved after a future transition to quantum-resistant signatures. He raised the idea during a June 18 podcast appearance, arguing that long-dormant wallets secured by older cryptography would be the first targets once a sufficiently powerful quantum computer exists.

The proposal sits inside a broader and unresolved disagreement among Bitcoin developers. A draft standard known as BIP-361 would let holders migrate coins to quantum-safe addresses and would eventually freeze legacy wallets that fail to move, including an estimated 1.7 million coins tied to early pay-to-public-key outputs. Satoshi's untouched holdings are the largest single block within that set.

The underlying tension is sharp. Freezing coins, even to prevent theft, means the network's participants would override the control of a wallet whose owner has not consented, which works against the idea that valid private keys alone control funds. Supporters respond that doing nothing leaves those coins available to whoever first builds the machine to break their cryptography, which would itself be a form of confiscation and a sudden increase in available supply. Both sides agree the threat is not imminent. The disagreement is whether the remedy preserves or violates the rule that makes Bitcoin credible.
