CoinJoin

On 22 August 2013 Maxwell, posting as gmaxwell, opened the Bitcointalk thread “CoinJoin: Bitcoin privacy for the real world”, arguing that Bitcoin's only privacy came from pseudonymous addresses that are “fragile and easily compromised”[1].

Block size war

Fork Wars cites a May 2015 bitcoin-dev post in which he argued that hard-fork changes “should only be made if they're almost completely uncontroversial”[2]. It treats his December 2015 “Capacity increases for the Bitcoin system” as a SegWit-first plan with further increases “when justified”, not a 2 MB pledge[2]. He is listed among the signatories of that roadmap[3].

Blockstream

Blockstream was founded in 2014 by Adam Back with developers including Pieter Wuille and Gregory Maxwell[4].
