On Nov. 15, 2022, a post was created on the forum website bitcointalk.org and the thread’s creator asked people to share signatures tied to some of their oldest mined bitcoin blocks. 11 days later, a newly created bitcointalk.org profile, called “Onesignature,” shared a signed message tethered to an extremely old block reward created on Jan. 19, 2009. The key was associated with bitcoin block 1,018 which was created 16 days after Satoshi Nakamoto launched the network.
