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.

My UK publisher, Head of Zeus, has published the official tour schedule for the British tour for Walkaway, with stops in Oxford (with Tim Harford), London (with Laurie Penny), Liverpool (with Chris Pak), Birmingham, and the Hay Literary Festival (with Dr Adam Rutherford). Hope to see you there!
My publicist just found an extra box of the cool promotional Walkaway multitools, and she’s generously offered to give them to the next 100 people to reserve tickets to the May 7th Walkaway event at Chicago’s Royal George Theater, where I’m presenting with CARDS AGAINST HUMANITY creator Max Temkin (current ticket-holders, don’t worry, you get […]
Carol from Cheapass Games writes, “In our continuing quest to bring back the very best classic Cheapass Games, we’re creating a new boxed set of Button Men, our strategy dice combat game. This time around, the characters will appear on cards, rather than pin-back buttons, but since they’re all 1950s era gangsters, the ‘button men’ […]
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
