7.12 million Bitcoin public keys exposed, 35.4% of supply

Glassnode reported that 7.12 million BTC—35.4% of supply—sits in addresses with exposed public keys, while ChainQuery put the figure at 7.16 million BTC (35.6% of circulating supply) as of block height 975,029. ChainQuery's breakdown shows 1.94 million BTC in outputs whose keys were exposed at creation and 5.22 million BTC left in addresses whose public keys were revealed by past spending. Exposure does not mean private keys have been compromised or coins are moving; it reflects blockchain-visible key data. The distinction matters because exposed public keys are the focus of quantum-computing concerns over Bitcoin's cryptography. The differing figures stem from separate snapshot dates and classification methods, so watch for a standardized methodology and any protocol-level proposals to migrate exposed coins to quantum-resistant addresses.
