Quantum exposure Always-exposed by design

P2TR · always-exposed

Taproot (P2TR) addresses use the x-only tweaked public key directly as the bech32m address. There is no hash layer in front (BIP-341); the pubkey is on chain from the moment of first funding. A sufficiently powerful quantum computer could derive the private key from the visible pubkey.

First revealed at block 836,695 on 2024-03-28 (p2tr_output).

foundryusa reward address (coinbase-extracted)

Received block rewards as part of foundryusa's coinbase output across 12521 block(s) between heights 838781 and 880227. Attribution derived from on-chain coinbase scriptSig tag matching plus Jameson Lopp's blocks.csv mapping; this is hard evidence the address received pool rewards under that pool's signature, not clustering inference.
