New York Agreement (SegWit2x) signed

Convened by Barry Silbert's Digital Currency Group on the eve of Consensus 2017, some 58 companies and mining pools controlling roughly 80-85% of hashpower signed a closed-door pact to activate SegWit and then hard-fork to 2MB blocks within six months. The deal that was supposed to end the block-size war instead set up its final act, as the "2x" half collapsed six months later for lack of consensus.
