P2PKH · reuse-exposed

P2PKH addresses hide the pubkey behind a SHA-256 + RIPEMD-160 hash UNTIL the first outgoing spend, which reveals it in the signature script or witness data. This address has been spent from, so its pubkey is permanently on chain. Every subsequent UTXO at this address is just as exposed as the moment of first spend.

First revealed at block 334,921 on 2014-12-19 (input_spend).

Received block rewards as part of eclipsemc's coinbase output across 82 block(s) between heights 334481 and 400824. 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.
