We’ve been saying for a long time that we need “something like a CAP theorum for IPLD.” By this, I mean that we need a way to talk about the design tradeoffs that are made when designing data structures in IPLD.

This is going to end up looking a lot different than the CAP theorem but the end goal is to have something that provides us a blueprint for how to discuss the performance tradeoffs of different data structure designs.

Anyway, here’s my attempt at a first draft. It’s incomplete but I need some feedback in order to iterate on it and turn it into a proper PR.

I've known people at nodejitsu for years, since before the company even existed. I still consider many of them friends. That said, somebody over there has lost their mind.

Trademarks are an important part of open source. They protect the integrity of the trust that is built by any project. A classic example of why this is the case is Firefox. Suppose that a malware producer takes the Firefox codebase, which is free and open source, packages up their malware with it and then releases it as "Firefox". Then they buy search advertising and suddenly their bad and malicious version of Firefox is the first result on search engines across the web. This is clearly a bad thing for Firefox and open source everywhere, but what can Mozilla do to protect their community of users?

They can't enforce a software license since the use is permitted under the Mozilla Public License. They can, however, enforce on these hypothetical bad actors using their trademark on the word "Fi
