hashcash

🗣️ 80 000 $BTC , whose movements have been actively tracked recently, belong to Adam Back — a British cryptographer, creator of #Hashcash , he is one of the few who personally communicated with Satoshi Nakamoto via e-mail in the early years of the project.

According to version #HBO , it is precisely Adam Back and Peter Todd who together form a kind of "collective" image of Satoshi Nakamoto — considering Adam Back's vast experience in cryptography, the number of wallets he controls may be much larger than we can imagine.

17 years ago, Satoshi Nakamoto wrote a letter to Adam Back (author of #Hashcash ).

In 2008, he was working on an article where he planned to reference the work "Hashcash - a DDoS protection mechanism." In the letter #Сатоши :
– asked Back to verify the quote,
– outlined the idea of an "electronic cash system" based on Proof-of-Work,
– suggested downloading the draft and contributing to the development of open-source code.

72 days later, #Whitepaper Bitcoin was published.
