That’s configurable by homeserver owner, it’s just a default value
It's kinda dead now since most active members migrated to another room, give me your MXID if you wanna join 😁
That's configurable by homeserver owner, it's just a default value
Source code and details: https://git.anarchists.space/nemesis/Vigil
A privacy-friendly anti-spam system for account registration on a public Matrix Synapse homeserver. Before an account is created, the client solves an Argon2id puzzle that is intentionally slow and memory-intensive, taking approximately 30 minutes by default, though the homeserver owner can configure the duration. This makes large-scale bot registration expensive.
Synapse's own open registration gets turned off; Vigil is the only thing that can create an account, and it only does that once a client proves it solved a fresh puzzle.
Features
- Privacy-friendly
- A lot harder to bypass than traditional anti-spam systems
- Optional CLI tool to solve cryptographic challenges for people who don't wanna use JavaScript
- Small codebase
Codebase is small and easy to audit. The panic button wipes all chat history in a room and blocks future messages. OnionShare fully depends on Tor’s built-in encryption for message security while NanoChat has its own encryption, which means you can host it on different anonymity networks.
Anubis is for blocking AI crawlers, not DDoS attacks
There are no user identities (not even cryptographic ones), and room encryption key is stored in URL which is never sent to server. Anyone can choose any nickname and you can access official instance (https://nanochat.anarchists.space/) through Tor.
We were under attack from a Singaporean botnet for two weeks, so I had to put our Forgejo instance behind Cloudflare because of that 🥲
