联网：ProtonVPN等 + Tor Browser等
- Online: ProtonVPN etc. + Tor Browser etc.
断网：蓝牙/本地WiFi + Briar等（信号屏蔽、断网情况之下的，某种互联。使得相关机构，需要安排大量的资源和人力，才能尽可能地，将事发地的人与事，进行全域覆盖和筛查。采取这样一种，不解决问题、解决提出问题的人，的处理和应对方式，又无形之中，增加了维稳的巨量成本。）
- Offline: Bluetooth/local WiFi + Briar etc. (A kind of interconnection under the situation of signal shielding and disconnection. It makes the relevant agencies need to arrange a lot of resources and manpower to cover and screen the people and events in the incident area as much as possible. Taking such a way of dealing with and responding to the problem by not solving the problem but solving the person who raises the problem, it also invisibly increases the huge cost of maintaining stability.)
- For complete anonymity, there is the Nostr series.
