- Coinbase's advisory council—including Scott Aaronson (UT Austin), Dan Boneh (Stanford), and Justin Drake (Ethereum Foundation)—says quantum computers aren't a current threat to Bitcoin but argues technical migration to post-quantum signatures should begin immediately, separate from the governance debate.
- Roughly 6.7 million bitcoin are exposed to future quantum attacks, including about 1.7 million sitting in approximately 20,000 early pay-to-public-key addresses likely tied to Satoshi Nakamoto and other lost-key holders who can never move them to safety.
- Project11 estimates another 5 million or so bitcoin are exposed through address reuse, though most of those are believed to be active holdings in exchange wallets rather than permanently abandoned coins.
- The council refused to pick sides on freezing vulnerable coins, writing that there is no correct answer and noting the three leading proposals—Hourglass, BIP-361 from developer Jameson Lopp, and PACTs from Paradigm's Dan Robinson—are compatible and could be adopted together.
- The hard-deadline camp argues unmigrated coins must become unspendable to prevent a future quantum-capable state actor, potentially a sanctioned nation like North Korea, from stealing a stash large enough to crash Bitcoin's price and taint the network's legitimacy.
- The opposing camp calls any freeze confiscation and a violation of the absolute property rights Bitcoin was built on, warning it sets a precedent for government-pressured coin seizures later.
- The report's two firm commitments: start the engineering work on post-quantum signatures now and give users clear communication, noting Ethereum has already spent years on post-quantum preparation while Bitcoin has not acted.
Why it matters: About 6.7 million bitcoin—roughly a third of all mined BTC—sit in a governance no-man's-land: technically exposed to a future attack, politically radioactive to freeze. The panel's refusal to choose means the burden shifts to the wider Bitcoin community, which must now weigh preventing a catastrophic state-actor heist against upholding the protocol's immovable property-rights ethos—with no consensus mechanism yet in place to resolve it.
