Controversy

In 2019, the Bitcoin community had its eye-rolling when Amaury Sechet, the self-described “benevolent dictator” of the Bitcoin ABC claimed he was Satoshi Nakamoto in a tweet ^[3]. Although bitcoin core developer Gregory Maxwell claims that pretending to be Satoshi could be easier than expected, and according to some hypotheses, Amaury Sechet would be joking,^[7] perhaps just to show how easy it can be to try to pretend to be Satoshi. In other tweets, he said ^[5]

Crypto Coin News asked me about being Satoshi. I obviously told them I was. Because I am.

However, in an interview with CCN in 2019, Amaury Sechet said he didn't create Bitcoin and the move was a demonstration of what other scammers have done. ^[6]

“It was a demonstration of what other scammers have done. It takes the wind out of their sails. Craig Wright, others before him. Others will do it after.”

“So, for example, a couple years ago Craig Wright claimed to ‘prove he was Satoshi’ by simply copying some pre-existing signatures out of the blockchain and posting somewhat obfuscated instructions on verifying them. It was figured out pretty quickly, but still managed to fool a lot of people– they were too caught up in the mumbojumbo to think of the obvious.”
