Overview
Blockstream is a Bitcoin infrastructure company founded in 2014 by cryptographer Adam Back alongside Bitcoin Core contributors including Pieter Wuille, Gregory Maxwell, Erik Svenson, and others. The company builds Bitcoin-focused technology across several product lines: the Liquid Network, a federated Bitcoin sidechain for faster and confidential asset settlement; self-custody hardware and software including the Blockstream Jade hardware wallet and Blockstream App; enterprise custody and treasury tools under Blockstream Enterprise; and Core Lightning, an implementation of the Lightning Network protocol. Blockstream's Bitcoin mining fleet/hosting business and the Blockstream Satellite service, which broadcasts the Bitcoin blockchain globally, were spun out into the independent company Blockstream Mining in 2025; its ASIC chip-design division was separately spun out into its own independent company. Neither is part of core Blockstream's operations today.
Blockstream has raised more than $600 million in disclosed private financing since 2014, most recently a $210 million convertible note round led by Fulgur Ventures in October 2024 to fund layer-2 development, mining expansion, and growth of its corporate Bitcoin treasury. The company operates from a global, largely remote team with hubs including the Cayman Islands, the San Francisco Bay Area, Montreal, Victoria, Lugano, Milan, and Tokyo.
Private securities are speculative, illiquid, and involve risk of complete loss of principal. You should be prepared to hold private securities for an extended period; there is no assurance of a secondary market, an IPO, or other liquidity event. You are fully responsible for conducting your own due diligence. Pricing is indicative — nothing here is an offer of securities.
