P2WPKH · reuse-exposed

P2WPKH 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 685,750 on 2021-06-01 (input_spend).

Received block rewards as part of f2pool's coinbase output across 329 block(s) between heights 685347 and 691063. 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.
