Glassnode: Public Keys of 6.04M BTC Exposed Onchain, 30.2% of Supply
- —Public keys of 6.04M BTC, 30.2% of supply, are exposed onchain per Glassnode
- —1.92M BTC exposed by address structure, 4.12M via reuse and partial spends
- —BIP-360 proposes P2MR output type removing key-path key exposure
- —BIP-361 would restrict sends to vulnerable addresses and tighten ECDSA/Schnorr after 3 and 5 years
Why it matters: Bitcoin's quantum migration hinges less on new signatures than on proving ownership of legacy coins, risking loss of access for inactive holders.
