Adam Back responded to the crypto community's speculation on the X platform that "Blockstream founder Adam Back is Bitcoin founder Satoshi Nakamoto". He said that he entered the bitcoin-wizards IRC channel in 2013 and asked a lot of Bitcoin technical questions, such as address balance and UTXO, and provided the IRC channel log at the time, indicating that he was still learning about Bitcoin. Adam Back pointed out that although he learns quickly and is creative, he did not propose concepts such as Schnorr signatures, confidential transactions, mining decentralization, client verification, and side chains until the second half of 2013, further proving that he is not Satoshi Nakamoto.
