- In Comm, each community is hosted on somebody's keyserver. - You can set up a keyserver on your laptop or in the cloud. - Comm won't host your keyserver for you. (We don't want to have access to your data!) - You don't need a keyserver to join a community, but you do need one to create a community. Keyservers enable us to offer the sort of sophisticated feature set that typically relies on corporate servers on the cloud, without sacrificing the privacy of our users. - Each community on Comm contains a tree structure of chat threads. Our threads are sort of like channels in Discord, but they can be nested inside each other. - Comm supports "sidebars", which are sort of like threads in Slack. Sidebars are created in response to a message in a parent thread. - Along with the default chat functionality, Comm also supports a library of apps to customize your community. We're launching with a Calendar app, and have more apps in the pipeline!

Self is the privacy-first way to prove you're human and verify who you are online (or give your agent a secure identity), without handing over your personal data. Trusted by Google, Opera, and 15M+ users. Verify your real-world identity once using a biometric passport, biometric national ID cards, Aadhaar, or any other supported identity document. Once registered, you can prove the specific attributes services require, such as your humanity, age, or nationality, without ever disclosing the underlying document or your personal information. Key Features: PROOF OF HUMAN: Prove you're a real person rather than an automated or duplicate account. AGE VERIFICATION: Confirm you're over 18 (or any age threshold) without revealing your birthday. Built for social apps, marketplaces, and age-gated services. PRE-KYC: Verify your eligibility (age, country of residence, sanctions, etc.) before any KYC process, only sharing your personal information with companies and institutions once necessary. AGENT ID: Delegate your identity credentials to your autonomous agent, unlocking broader utility and access across the internet. PRIVACY BY DESIGN: Self is using the latest zero-knowledge technology, fully audited by the world’s best security experts. All data is stored locally on the user’s device — never on any servers. When a user verifies their identity, a verifiable credential is created and saved securely in the app. There’s no cloud storage, no centralized database, and no way for anyone - including Self - to access the data without the user's consent. "We’re committed to ensuring developers can build faster with reduced friction while maintaining industry‑leading security standards," said Rich Widmann, Google. "Integrating Self allows us to further this mission with frontier zero‑knowledge solutions." Why Self Defend against bots and duplicate identities Meet age and compliance requirements without surrendering personal information Carry one verified identity across the apps you use, instead of re-uploading documents at every sign-up Help establish a global standard for verified identity that keeps people, not platforms, in control of their data
