=== Abstract ===
  : //This document specifies a BIP16 like [[dido:public:ra:xapend:xapend.a_glossary:s:soft_fork|soft fork]] flag day activation of the segregated witness BIP9 deployment known as "segwit"((
"existing segwit deployment" refers to the [[https://github.com/bitcoin/bips/blob/master/bip-0009.mediawiki | BIP9 ]]"segwit" deployment using bit 1, between November 15th 2016 and November 15th 2017 to activate [[dido:public:ra:xapend:xapend.b_stds:defact:bitcoin:bips:bip_0141| BIP141]], [[dido:public:ra:xapend:xapend.b_stds:defact:bitcoin:bips:bip_0143| BIP143 ]], and [[dido:public:ra:xapend:xapend.b_stds:defact:bitcoin:bips:bip_0147| BIP147]].
)).//
  
=== Motivation ===
  : //Segwit increases the blocksize, fixes transaction malleability, and makes scripting easier to upgrade as well as bringing many other benefits.//

  : //It is hoped that miners will respond to this BIP by activating segwit early, before this BIP takes effect. Otherwise this BIP will cause the mandatory activation of the existing segwit deployment before the end of midnight November 15th 2017.//
