The wiki's angle: Blockstream is the big-block side's favourite villain in fork history. This wiki sticks to what is documented: its founders' signatures on the 2015 roadmap and the Hong Kong statement.[2][3]

Blockstream was founded in 2014 by cryptographer Adam Back with Bitcoin developers and cryptographers including Pieter Wuille and Gregory Maxwell[1]. It is headquartered in Menlo Park, California, and raised $21 million in seed funding in 2014[1]. In August 2021 it raised $210 million at a $3.2 billion valuation[1].

In the block size war

Back, Maxwell and Wuille are among the signatories of the December 2015 roadmap “Capacity increases for the Bitcoin system”[2]. Back signed the February 2016 Hong Kong Roundtable statement as Blockstream's President[3].

Recent

In July 2026 Blockstream and Cantor Fitzgerald cancelled a planned SPAC merger that would have listed Blockstream on Nasdaq, citing “current market conditions”[1].
