== Goal of this meeting ==
Weekly check-in about the status of anti-censorship work at Tor.
Coordinate collaboration between people/teams on anti-censorship at the Tor Project and Tor community.

== Announcements ==
*
== Discussion ==
* what to do with moat bridges once we turn off BridgeDB?
* The plan is to switch off BridgeDB on 2024-09-09.
* Currently, moat bridges are reserved exclusively for moat. When rdsys stops distributing moat bridges, those bridges will get no new users. They will only have the users that already knew about them. (The "request bridge" button in Tor Browser uses moat, after the switch the button will get bridges from circumvention settings instead.)
* meskio will configure rdsys so new bridges are not assigned to that distributor
* meskio will monitor the usage of moat bridges to decide when to move them somewhere
* During the transition period, the request bridge button will display a captcha (because Tor Browser is expecting one), but it will be a placeholder captcha: https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/issues/182 https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/blob/617c6ced3900e2bbe462605a6f68aaebba6e0582/pkg/presentation/distributors/moat/captcha.jpg
== Actions ==
== Interesting links ==
== Reading group ==
* We will discuss "SpotProxy: Rediscovering the Cloud for Censorship Circumvention " on September 12
* https://www.cs-pk.com/sec24-spotproxy-final.pdf
* https://censorbib.nymity.ch/#Kon2024b
* Questions to ask and goals to have:
* What aspects of the paper are questionable?
* Are there immediate actions we can take based on this work?
* Are there long-term actions we can take based on this work?
* Is there future work that we want to call out in hopes that others will pick it up?

onyinyang: 2023-08-29
Last week(s):
- continued with key rotation integration work
- collected issues and TODOs for all Lox work that needs to be done before deployment
Next week:
- finish up key rotation integration work
- add pref to handle timing for pubkey checks in Tor browser
- update lox protocols to return duplicate responses for an already seen request
- add trusted invitation logic to tor browser integration:
https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42974
- Work on outstanding milestone issues:
in particular: https://gitlab.torproject.org/tpo/anti-censorship/lox/-/issues/69
- key rotation automation
Later:
- begin implementing some preliminary user feedback mechanism to identify bridge blocking based on Vecna's work
- improve metrics collection/think about how to show Lox is working/valuable
- sketch out Lox blog post/usage notes for forum
(long term things were discussed at the meeting!): https://pad.riseup.net/p/tor-ac-community-azaleas-room-keep
- brainstorming grouping strategies for Lox buckets (of bridges) and gathering context on how types of bridges are distributed/use in practice
Question: What makes a bridge usable for a given user, and how can we encode that to best ensure we're getting the most appropriate resources to people?
1. Are there some obvious grouping strategies that we can already consider?
e.g., by PT, by bandwidth (lower bandwidth bridges sacrificed to open-invitation buckets?), by locale (to be matched with a requesting user's geoip or something?)
2. Does it make sense to group 3 bridges/bucket, so trusted users have access to 3 bridges (and untrusted users have access to 1)? More? Less?
