It appears Telegram also does not work without VPN in Russia.
We will be implementing connection rotation and redundancy it may reduce the impact. In any case, preventing transport-level blocking is a hard problem, especially if they start using LLM for traffic analysis. It is better to solve it in dedicated VPN solutions, not in the apps.

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: https://github.com/simplex-chat/simplex-chat/releases/tag/v6.5.0-beta.3
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: https://simplex.chat/reproduce/

Community Vouchers are pure utility tokens:
- can only be used to pay for servers
- cannot be traded
- cannot be sold
- have fixed price
- expire in 6-12 month.
This is not something you can "trade" or "invest" in.

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.

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!

Always happy to chat. Ethereum support for smart contracts and native support for zero-knowledge proofs being rolled out this year makes it the best choice to develop solutions that require network-wide consensus - there is no alternative. It's not a cryptocurrency choice as some people think.
This choice is purely technical, and not political or ideological - it's simply tech that at the moment works better than alternatives and is the most stable.
I commented some points on X, will repost here.

2025-10-30 13:42:53 CET

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: https://simplex.chat/token/
You can get a free NFT on Ethereum mainnet that will provide access to testnet when launched - planned for 2026.

What I mean is that Nostr relays can track which IP addresses read messages from which group IDs, creating an association with transport level identities of the users. While it's indeed mitigated to some extent by Tor/VPN, which was SimpleX design defence early on, the valid criticism of this argument that either Tor should be built into the clients (which wasn't and won't be the case with SimpleX, and is not the case with Nostr clients), as most users won't use Tor, and will assume that declared security properties hold without any additional measures.
What's worse is that even with Tor or VPN, Nostr relays can associate the list of group IDs with client sessions that read them, and observing sessions over time they would be able to statistically "recognise" users by the list of groups they get messages from. To mitigate this risk clients have to use different connections (and Tor circuits) when reading from different groups, and it's neither practical nor part of the spec. SimpleX clients offered this feature (transport isolation) as opt in.
So the response of SimpleX network design that addressed this criticism was using two independent relays in the message routing path, where the first one can see client session and transport address, but cannot see destination message queue address. And the second relay can see destination queue address, but has no information that could identify the transport session of the client. And the clients are programmed to choose relays operated by different parties to mitigate collusion risks.
What I was saying about our future chat relays design is that they are the usual messaging clients under the hood, just high volume, and won't have any network connection to the group members, even an indirect one, as they will be communicating via the existing messaging network.

As for address rotation, it's currently possible manually, so they are not completely static, and this feature is used a lot, and it will be automatic next year. The challenge with automatic rotation is reduced usability - data backups do not allow restoring connections, so it requires smarter approach to make sure that the solution is usable.

2025-08-13 09:18:29 CEST

- reply

This has the same problem that was drawing criticism with early design of SimpleX network - while there is no persistent/observable identity on the protocol level, there is a fixed transport identity - relays can see which IP addresses communicate with which IP addresses. So it would require a similar solution to what we did with SimpleX network to mitigate it.

An essay explaining why we don't plan to use MLS: https://www.poberezkin.com/posts/2025-08-12-mls-the-naked-king-of-end-to-end-encryption.html
A sidenote, is that Nostr's Whitenoise avoids its main problem.
TL;DR: MLS security model is "Trust me bro".

To address some incorrect criticism:
> Did you know @SimpleX Chat now has a blockchain/shitcoin built in (called Flux)?
Nope, that's not true. There is no built-in coin. Flux the company offers their servers to the app users. Not their coin.
> Did you know they've also started doing "content moderation"—blocking users, groups and 3rd party servers?
Also not true. We cannot block users, as there are no users, and we do not block 3rd party servers. We do remove addresses of groups that distribute CSAM from our servers, without any impact on users privacy.
> Yeah, so far it's only to stop CSAM distribution but we all know how that's a slippery slope. The good old "Think of the children" tactic. If there's a method to ban, block or censor, it will be used and ABUSED.
Not true. Freedom of speech without SOME restriction cannot exist - unlimited freedom always leads to abuses of power and tyranny. Study some history. Our freedom ends where the freedom of our neighbours starts, so some limits absolutely must exist to defend our freedom.
> SimpleX Chat ... not decentralized
Not true as well - there are 100s if not 1000s of community run servers. If you don't want to use ours or Flux's, use your own or anybody else's - it's all in a single network.
> not censorship-resistant.
This is correct, and this will change, as was explained in livestream.
Censorship-resistance and privacy are technically contradictory requirements, so they have to be balanced.
> I also found out they are getting funded by VCS such a Village Global
We were never hiding it, and who are it's LPs is irrelevant - they have no influence or control on SimpleX Chat.

5. Does the company log timestamps/IP addresses? Yes
This is incorrect, we never logged IP addresses and access timestamps of the users.

4. Directory service could be modified to enable a MITM attack? Yes
This is incorrect, as there is no user directory service at all (and no knowledge of even the number of users), and MITM by servers is not possible by design, even without optional security code verification (that exists to mitigate MITM by the channel you used to pass one-time invitation link, e.g. email).
