Quantum exposure Reuse-exposed

P2SH · reuse-exposed

P2SH 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 551,886 on 2018-11-29 (p2sh_redeem_reveal).

poolin reward address (coinbase-extracted)

Received block rewards as part of poolin's coinbase output across 1328 block(s) between heights 551647 and 571278. 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.
