Quantum exposure Not exposed

Not currently exposed

This address does not appear in ChainQuery's revealed_addresses registry. Either it has never been spent from (the pubkey is still hidden behind its hash) or it has never received funds. Hashed-type addresses (P2PKH, P2WPKH, P2SH, P2WSH) remain quantum-safe under current cryptography until the first outgoing spend reveals the pubkey.

ocean reward address (coinbase-extracted)

Received block rewards as part of ocean's coinbase output across 43 block(s) between heights 918568 and 930920. 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.
