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 857,181 on 2025-04-22 (nested_witness_reveal).

What we know about this address 1 findings

ocean reward address (coinbase-extracted)

Received block rewards as part of ocean's coinbase output across 271 block(s) between heights 898303 and 925450. 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.
