Alex Thorn, Research Director at Galaxy Digital, said the Bitcoin community is gradually reaching an initial consensus on the quantum-computing threat. The dominant view holds that Satoshi Nakamoto's P2PK-addressed assets should not be interfered with, in order to preserve Bitcoin's core ownership attributes.
Thorn's framing rests on a structural detail: the roughly 1.1 million BTC attributed to Nakamoto is not held in a single address but distributed across approximately 22,000 P2PK addresses, averaging around 50 BTC each. That fragmentation means a future quantum attacker would not unlock a single billion-dollar wallet in one move — they would have to break 22,000 separate signatures, a materially harder problem than the public narrative suggests.
Why it matters
The quantum debate in Bitcoin has long been framed as a binary: a sufficiently powerful quantum computer could one day derive private keys from exposed public keys and drain early-mineable coins. The consensus Thorn describes reframes it as a phased engineering challenge rather than an existential cliff — the more interesting question becomes which address types (P2PK first, then reused P2PKH) get deprecated via soft fork, and on what timeline.
Market impact
For now the read-through is muted. With the largest quantum-exposed tranche (Satoshi's stash) effectively treated as politically off-limits, attention shifts to the smaller pool of legacy P2PKH addresses with exposed public keys, and to the migration mechanics a future soft fork would impose. No protocol action is imminent, and $BTC price reaction to the comments was negligible.
Frequently asked questions
-
What did Alex Thorn say about Bitcoin and quantum computing?
Thorn, Galaxy Digital's research director, said the Bitcoin community is gradually reaching an initial consensus that Satoshi Nakamoto's P2PK-addressed coins should not be interfered with, in order to preserve Bitcoin's core ownership attributes.
-
Why is Satoshi's BTC stash considered hard to attack quantumly?
The roughly 1.1 million BTC attributed to Nakamoto is distributed across approximately 22,000 P2PK addresses averaging around 50 BTC each. A quantum attacker would have to break 22,000 separate signatures rather than drain a single wallet in one move.
-
Are P2PK and P2PKH the same thing?
No. P2PK (Pay-to-Public-Key) is an older, simpler script type used in early Bitcoin blocks; P2PKH (Pay-to-Public-Key-Hash) is the more common modern address format. P2PK addresses expose the public key directly on-chain, making them the most quantum-exposed address type.
-
Would a quantum attack on Satoshi's coins require a soft fork?
Satoshi's coins have never been moved, so the corresponding private keys have never been revealed. Any future quantum attacker would first need to derive those keys from the exposed public keys, then sign a valid transaction — a hard problem, not a foregone conclusion. The community consensus Thorn describes treats…

How did $BTC react to Thorn's comments?
There was no notable market reaction. The quantum threat remains a long-tail, multi-year engineering question rather than a near-term catalyst, and the price of $BTC was effectively unchanged in response to the remarks.
