 It's been [nearly a year](./20210914-simplex-chat-v0.4-released.md) since the users of SimpleX Chat terminal app started experimenting with the groups, and now it is available to mobile app users as well. Many bugs were fixed, the stability was improved, but there are both the features we need to add and the bugs we need to fix to make groups more useful - we really look forward to your feedback. You can send any suggestions via the app by choosing `Chat with the developers` via app Settings (or using `/simplex` command in the terminal app) – this would connect you to SimpleX team via its [fixed chat address](https://simplex.chat/contact#/?v=1&smp=smp%3A%2F%2FPQUV2eL0t7OStZOoAsPEV2QYWt4-xilbakvGUGOItUo%3D%40smp6.simplex.im%2FK1rslx-m5bpXVIdMZg9NLUZ_8JBm8xTt%23MCowBQYDK2VuAyEALDeVe-sG8mRY22LsXlPgiwTNs9dbiLrNuA7f3ZMAJ2w%3D).
 
-SimpleX network is decentralized, so how do groups work? Unlike Matrix or Signal that host the group profile and the list of group members on their servers, SimpleX servers have no information about the group's existence - only its members do. SimpleX network does not assign any globally unique identifiers to the group, there is only a local database identifier and the list of members stored on members' devices. A user has an independent connection to each member in a group. When a user sends a message to the group, the app sends this message independently to each member. You can read more about how groups work in [SimpleX Chat Protocol](../docs/protocol/simplex-chat.md#sub-protocol-for-chat-groups).

 But how can it scale, you might ask? It simply won't, and the current design for the groups is only suitable for relatively small groups of people who know each other well, definitely not larger than few hundred members – this design prioritized privacy and security of the group over its size or performance. For example, to send a message to the group of 100 members a user would need to send a total of ~1.6mb of data (as each message uses a fixed size block of 16kb). And if you were to send a 1mb file then it would also require sending it 100 times (provided each member accepts it).

 This release allows to access SimpleX messaging servers via Tor on all platforms:

 - Android app supports access via Tor using Orbot SOCKS proxy. Once you install and start Orbot, you need to enable `Network & Servers / Use SOCKS proxy` setting in the app to access SimpleX servers via Tor.
 - iOS app can also be used with Orbot iOS app (that is installed as a system-wide VPN provider). The only setting you might need to change is to increase network timeouts in the app - to do that you have to enable `Developer tools`, and then chose `Network & Servers / Advanced network settings / Set timeouts for proxy`.

 The [low level SimpleX protocols](https://github.com/simplex-chat/simplexmq/blob/stable/protocol/) were published long time ago, and updated to reflect the evolution of the protocols, the high level chat protocol was not published before. The reason for that was to allow us to iterate it quickly, without committing to any of the decisions.
