Jameson Lopp: quantum computers are far from breaking Bitcoin
- —Lopp: a usable quantum computer that breaks ECDSA is still far off
- —6.26M BTC (31.2% of supply) held in addresses with exposed public keys
- —1.71M BTC in old P2PK addresses, some attributed to Satoshi
- —BIP-360 and BIP-361 propose migration to post-quantum signatures
Why it matters: The quantum threat isn't imminent, but migrating legacy addresses will be Bitcoin's key technical challenge in the coming years.
