Glassnode estimates that 7.12 million BTC, or 35.4% of Bitcoin's supply, has public keys already visible onchain. A powerful enough quantum computer could one day use those keys to derive private keys.
And the interesting part is why those keys are exposed.
For most common Bitcoin address types, the public key stays hidden until you spend from that address. Once you do, the key becomes permanently visible onchain. Any BTC left at that address, or sent there later, becomes exposed.
Here's Glassnode's breakdown:
- 25.8% of Bitcoin's supply is exposed through address reuse, including 11.6% held at exchange-linked addresses.
- Another 9.6% is exposed by design, mainly through older P2PK outputs and Taproot.
That means nearly 73% of Bitcoin's current exposure comes from address reuse, something holders can address today by moving their BTC to fresh, unused addresses.
No protocol upgrade needed, just a transaction.
Since 2017, exposure from address reuse outside exchanges has fallen from roughly 21% to 14.2% of supply. Meanwhile, exchange-related exposure has climbed to 11.6%.
In other words, more of this exposure is now concentrated at exchanges.
Moving BTC to a fresh address reduces exposure while the coins sit there. But spending them again can reveal the public key before the transaction confirms. Fully addressing that risk will require quantum-resistant signatures.
We don't yet have a quantum computer capable of breaking Bitcoin's cryptography. And that's precisely why now is a good time to address the risks we already know how to reduce.
Heads up:
As the next phase of qms testnet makes a return next month. So, while waiting;
It's best to remind you that QMS is looking for experienced developers and teams building DeFi, trading apps, stablecoins, PQSAs, wallets, agents, etc
