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 964,001 on 2026-08-25 (p2sh_nested_p2wpkh_reveal).

btccom reward address (coinbase-extracted)

Received block rewards as part of btccom's coinbase output across 1049 block(s) between heights 834355 and 965928. 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.
