According to BlockBeats, on October 8, Blockstream CEO Adam Back responded to the reasons for not being Satoshi Nakamoto, saying, "In 2013, I joined the Bitcoin wizards IRC and asked a lot of questions to learn more about Bitcoin. For example, the balance held by the address and utxo coins, etc. There are records in the logs of the IRC channel, so the developers in the channel are sure that it is not me. I learned quickly and proposed schnorr signatures, transaction ductility fixes (similar to segwit), confidential transactions (now applied to Liquid Network), commitment TX, pooled decentralization (such as stratum V2), client verification, side chains, etc. in late 2013."
