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 691,779 on 2021-07-19 (input_spend).

marapool reward address (coinbase-extracted)

Received block rewards as part of marapool's coinbase output across 509 block(s) between heights 699954 and 736992. 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.
