# Bitcoin Block 170 **Domain:** Cryptocurrency history / Settlement record **Doc Type:** Developed Wiki Node **Maturity:** Developed **Collection:** [[collections/Gamification|Gamification Collection]] ## Definition **Bitcoin block 170** contains the first non-coinbase spend generally recognized as a person-to-person Bitcoin transfer: 10 BTC historically attributed to Satoshi Nakamoto sending to Hal Finney. The block timestamp is approximately January 12, 2009 at 03:30 UTC, corresponding to the evening of January 11 in Pacific time. ## Significance The date variation is chiefly a timezone-rendering issue, not evidence of competing transactions. The identity attribution is an off-chain evidentiary bridge layered onto a cryptographic settlement record that does not itself name sender or recipient. ## Sources - [[articles/gamification/Lex Sportiva and Winning Without Bloodshed|Lex Sportiva and Winning Without Bloodshed]] - [Block 170 explorer record](https://mempool.space/block/00000000d1145790a8694403d4063f323d499e655c83426834d4ce2f8dd4a2ee) ## Routes [[wiki/Hal Finney|Hal Finney]] · [[wiki/Satoshi Nakamoto|Satoshi Nakamoto]] · [[wiki/Cryptoeconomic Settlement|Cryptoeconomic Settlement]] · [[wiki/January 9 2009 Cluster|January 9 2009 Cluster]]
