Bitcoin Scaling Watch: News & Guides to Navigate the Coming Clash of Code


As bitcoin heads into July, the protocol stands on the cusp of major changes to its code.

The result of years of heated discussion on how to expand the capabilities of bitcoin for greater transaction volumes, two key proposals now stand on the verge of potentially disrupting or upgrading the network.

While generally described as a “civil war,” the battle over bitcoin’s technical roadmap is more nuanced.

Yet, that’s not to say there couldn’t be real consequences.

To help readers understand this turbulent time, we’re assembling content, both new and old, to serve as a guide to the debate and a real-time way to track news and updates.

In the days to come, we’ll be updating this post as a resource. We’re happy to consider collaborations and improvements as we seek to inform the world about changes and movements in bitcoin code.

Guides & Explainers

Along the way, we’ll release new guides and explainers aimed at taking high-level looks at some of the more granular aspects of the code proposals.


The most widely supported (and most controversial proposal), Segwit2x has perhaps the greatest chance of being activated.

In this explainer piece, Alyssa Hertig outlines (in simple terms) what the proposal aims to do, what inspired it and how it works.

BIP 148

In response to perceptions miners and startups are pushing their view on the bitcoin roadmap, some users have threatened revolt.

BIP 91

A complement to Segwit2x, BIP 91 may well end up mediating between the two proposals.

Here, Alyssa Hertig and Bailey Reutzel outline how it works, who’s running the code and what will happen if (and when) it goes live.
