Dr. Adam Back, CEO of Blockstream, received the first email from Satoshi about Bitcoin, but now focuses on developing infrastructure and scaling solutions at Blockstream. Blockstream's innovations include the Liquid Network, a sidechain for faster and more confidential transactions, and a hardware wallet that allows for trustless trades without giving up custody. Back believes that the identity of Satoshi is becoming less important as Bitcoin continues to function as a decentralized system. SideSwap, a startup, offers a trustless central order book for companies around Liquid and has created their own hardware wallet for faster innovation. Blockstream CEO Adam Back believes that the altcoin market has become saturated with over 3 million coins, including memecoins, but there is still room for improvement in scaling blockchains.
