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 676,875 on 2021-03-29 (input_spend).

miningdutch reward address (coinbase-extracted)

Received block rewards as part of miningdutch's coinbase output across 25 block(s) between heights 819035 and 950154. 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.
