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."

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!

An essay explaining why we don't plan to use MLS:
A sidenote, is that Nostr's Whitenoise avoids its main problem.
TL;DR: MLS security model is "Trust me bro".
