At the end of November, an unknown person signed a signature tied to an extremely old block reward mined on Jan. 19, 2009, and the user published a message and verified signature linked to the reward on the forum bitcointalk.org. The message was tied to a bitcoin address associated with block 1,018, a block reward that was minted 16 days after Satoshi Nakamoto launched the network. Upon further investigation, onchain data shows that block 1,018 is linked to a great number of block rewards ostensibly mined by Hal Finney, and the signed block is also connected to the very first bitcoin transaction that derived from block 9.

Nakamoto's Neighbor: My Hunt For Bitcoin's Creator Led To A Paralyzed Crypto Genius

Hal Finney's light brown eyes are pointed down.

I've just asked him if he was involved in the creation of Bitcoin. The 57-year-old man's almost imperceptible eye movement is his only way of telling me that he was not, and that I've spent the last week caught in the same futile windmill-tilting that has ensnared so many other reporters trying to solve the puzzle of Bitcoin's mysterious creator known only as Satoshi Nakamoto.
