Tools like Etherpad and Google Docs are transformative ways to collaborate on text (including code); I've used them in contexts as varied as making unofficial transcripts of statements at UN agencies to liveblogging conference presentations -- but they all share a weakness, which is that whomever owns the document server can see everything you're typing.
Cryptpad is a free/open project that uses some of the ideas behind blockchain to implement a "zero-knowledge" version of a collaborative document editor, ensuring that only the people working on a document can see it. The crypto keys are stored in a "fragment identifier" in the URL, so sharing the URL is the same as sharing permission to read and edit the doc. It's on Github, and licensed GPL V3.
CryptPad uses a variant of the Operational transformation algorithm which is able to find distributed consensus using a Nakamoto Blockchain, a construct popularized by Bitcoin. This way the algorithm can avoid the need for a central server to resolve Operational Transform Edit Conflicts and without the need for resolving conflicts, the server can be kept unaware of the content which is being edited on the pad.

After years of hearing a steady drumbeat about the necessity of surfing the web under the protection of a VPN, even the most technophobic among us are starting to come around. But even knowing the dangers one can face from cybercrooks phishing for information from unsuspecting victims online, those last holdouts still have some fears. […]
You may not realize it, but some of the biggest films in movie history have been edited using the same tools some of you use to cut your video of vacationing at Disney World. Giant movies from Oscar favorites The Social Network and Gone Girl to blockbusters like Avatar, Deadpool, and last year’s Terminator: Dark […]
Now that the initial furor and shortages have subsided, it’s probably not a bad time to start considering your long-term cleaning and disinfecting plans. Sure, that might seem anywhere from overly cautious to outright ridiculous, but the threat of COVID-19 appears poised to be present for a while and the need for quick travel clean-up […]
