We published the whitepaper about Community Credits - a closed loop prepaid payment system to fund servers and client application in decentralized SimpleX network: https://simplex.chat/credits/whitepaper.pdf About Community Credits:

SimpleX Community Credits

Alain Brenzikoher presented it at Web3 Summit: SimpleX Community Credits: Making Privacy Profitable.

We updated SimpleX Chat Privacy Policy and Conditions. What changed: Stronger privacy commitments: - explicitly states that preset servers do not log IP addresses. - you can verify clients and servers via reproducible builds. quantum-resistant end-to-end encryption. - messages are irreversibly removed from preset servers on delivery or after 21 days. - transparency commitment by client apps. New private one-time connection links and public addresses: - your profile data is encrypted on the server - only people with the link can access it, not the servers. - one-time link profile data is removed once the connection is established. Public channels (beta): - chat relays are used to deliver messages to channel subscribers. - chat relays cannot identify subscribers. Commit with the change:

A big news for SimpleX Chat privacy and security: Android apps released via GitHub and F-Droid are now 100% reproducible! It means that you can easily verify that the app is secure, even if the download site was hacked. From v6.5 our release process is: 1) build Android apps on two independent machines and confirm they are 100% identical; 2) cryptographically "sign" them; 3) add signature files to the release page so you can verify. v6.5 beta.3 release:

New in v6.5-beta.3: fix opening new contact request on remote desktop. fix remote desktop failing to receive new events after error. iOS: fix dial...

Server and Linux desktop builds were already reproducible, and Android APKs are now as secure. Anyone can check it themselves - no coding needed, just follow our simple guide to verify the app is genuine or run the build yourself:

Our users asked many questions about Chat Control, as discussions were restarted in the EU this week. SimpleX Chat is an open-source app where users control the code and the servers they use. Therefore it is impossible to implement any client-side scanning, and it will not happen. If the law is passed, two options are possible: - we might need to stop offering preset servers to the EU users. - we will not need to change anything - this is the most likely outcome. Our operations are always consistent with our Privacy Policy (https://simplex.chat/privacy), and we would rather shut down than do anything that contradicts this agreement with our users.

"Code alone doesn't cut it. Not code alone, not code widely distributed, not even code widely used. Some measure of toleration in society for activities conducted in private is necessary for long term success. Not convenient, not easier, but necessary." Eric Hughes, "Kid Gloves or Megaphones" (email to Cypherpunk mailing list), 1996

Huge thank you to all for feedback and suggestions on Community Vouchers plan! FAQ: 1. Can we still use our servers? Yes, and it will be improved (read full FAQ). Community Vouchers are completely opt-in, and intended only for server payments by the large groups. 2. How is it possible to provide privacy on public blockchain? In the same way as we provide private communications on the public Internet - by using per-purchase addresses, not per user as in wallet apps, and by using zero-knowledge proofs to verify ownership. 3. How many Community vouchers will be pre-sold and available during public sale? None! No Community Vouchers will be made available to any insiders or to the public sale – it would have made them investment contracts. Community Vouchers are restricted utility tokens. 4. What problems do vouchers solve? - unlinkability of purchase to usage, thanks to zero-knowledge proofs. - trust to server operators - funds will be only unlocked to them after infrastracture is provided. - revenue sharing with network - it will be codified in blockchain contract. 5. Are you considering other blockchains? Yes, as long as they are sufficiently mature, and natively support smart contracts and zero-knowledge proofs. Send your suggestions!

We plan to adopt zkEVM networks for problems that require network-wide consensus: - public names - server registry - server infrastructure payments using Community Vouchers represented by SMPX utility tokens on some L2 network TBC Please read the plan and FAQ here:

An essay explaining why we don't plan to use MLS:

MLS: The Naked King of End-to-End Encryption

Evgeny Poberezkin

A sidenote, is that Nostr's Whitenoise avoids its main problem. TL;DR: MLS security model is "Trust me bro".
