Welcome!

First App

Blabber is the first app running on Semaphore with (hopefully) many more to come. Make an account! Send a Bleep! Visit blabber.social today. It is a simple demo, but is running on the live Semaphore network.

Literature

The fundamental problems of decentralized social networks are counterintuitive. This short writeup explains the mistakes in other projects, like email, and how Semaphore is different: Current Decentralized Social Networks are Doomed

Semaphore is the first decentralized blockchain without a cryptocurrency, which enables a protocol that functions without fees while also handling spam & personal moderation. This short writeup explains how building such a system is possible and what functionality the Semaphore design enables: Semaphore: Possibly not Doomed

How does Semaphore compare to alternatives?

Semaphore vs Farcaster

Semaphore vs Lens

Need a TL;DR? This short writeup is a very gentle introduction to the problems of centralized social networks and how Semaphore solves those issues: Semaphore 2-pager.

Need the opposite of a TL;DR? This not-so-short whitepaper has the technical details: Semaphore Whitepaper.
