Rafael Schultz Kraft: Approximately 6.26 million BTC public keys have been made public on the chain

Glassnode co-founder Rafael Schultz Kraft stated that the public keys of approximately 6.26 million BTC addresses have been made public on the chain, 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 about 1.94 million were related to script types. This statistic does not represent the feasibility of quantum attacks in reality, nor can it be used to evaluate the security status of exchanges or custodians.
