Glassnode co-founder: Approximately 6.26 million BTC public keys have been disclosed on-chain, accounting for 31.2% of the circulating supply

Co-founder of Glassnode, Rafael Schultze-Kraft, stated based on on-chain data that approximately 6.26 million BTC public keys have been exposed, accounting for 31.2% of the current supply, up from 24.8% at the beginning of 2021.

Among them, about 4.33 million were exposed due to address reuse, and approximately 1.94 million are related to script types. He emphasized that this statistic does not indicate that quantum attacks are realistically feasible, nor can it be used to assess the security status of exchanges or custodians.
