Finney's identification rests on the surrounding historical record, so attribution should distinguish on-chain evidence from off-chain testimony and correspondence. ## Sources - [[articles/gamification/Lex Sportiva and Winning Without Bloodshed|Lex Sportiva and Winning Without Bloodshed]] - [Hal Finney, Bitcoin and Me](https://bitcointalk.org/index.php?topic=155054.0) ## Routes [[wiki/Satoshi Nakamoto|Satoshi Nakamoto]] · [[wiki/Bitcoin Block 170|Bitcoin Block 170]] · [[wiki/Bitcoin v0.1|Bitcoin v0.1]] · [[wiki/Attribution Stack|Attribution Stack]]
