On November 15, 2022, a discussion was started on bitcointalk.org. The creator of the thread asked for signatures to be shared by anyone who was interested in sharing signatures which corresponded with their oldest mined Bitcoin blocks. After 11 days, a new bitcointalk.org profile had been created. “Onesignature” shared a signed message linking to a reward block from January 19, 2009, which was associated with Bitcoin block 1018, which was created 16 days after Satoshi Nakamoto launched the network.
Mysterious Person Signs Message Linked to BTC Block 1018, Reward Minted 16 Days After Bitcoin Launch
An unknown user named “Onesignature” signed a message linking to Bitcoin block 1018. This is an old reward from a block created on January 19, 2009. The owner of Bitcoin.org, known as “Cobra”, discovered the block signature. Cobra tweeted, “A user ‘Onesignature’ appeared and posted the signature of a key associated with block #1,018. For context, there are probably a handful of people in the world who can sign with a January 2009 key.”
The bitcointalk.org users have shared the signed messages of Onesignature for the first time a bitcoin address was viewed on December 2, 2022. The BTC address “1E9Yw” was the recipient of dust transactions and was first seen on April 15, 1999. The signature (HCsBcgB+Wcm8kOGMH8IpNeg0H4gjCrlqwDf/GlSXphZGBYxm0QkKEPhh9DTJRp2IDNUhVr0FhP9qCqo2W0recNM=) is associated with the Bitcoin address “1NChf”. The block reward (1018) was kept in the wallet until June 14, 2011.
A user also found that the coins mined and transferred in 2011 had “private keys from addresses that were mined before the address mentioned above.” People in the post speculated if Onesignature was actually Satoshi Nakamoto, however, Cobra provided more details on Twitter and said it was not an address from a “Patoshi block”, a block associated with the creator of Bitcoin. She said it was “unlikely out Satoshi.”
