Genesis Block Coinbase (Satoshi Nakamoto)

The 50 BTC subsidy from Bitcoin's genesis block. The original coinbase UTXO is structurally unspendable across most Bitcoin Core code paths because the genesis transaction is hard-coded as a special case. The address has received many subsequent donations over the years but has never spent a satoshi.

ckpool reward address (coinbase-extracted)

Received block rewards as part of ckpool's coinbase output across 1 block(s) between heights 539209 and 539209. 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.
