## Bitchat:动荡时期安全通讯 Bitchat是一款新的消息应用程序,旨在提供安全可靠的通讯,即使在没有互联网或蜂窝网络的情况下也能使用。它响应了巴勒斯坦人经历的通讯中断——以色列控制网络访问并经常造成干扰——Bitchat为WhatsApp等易受攻击的平台提供了一种重要的替代方案。 该应用程序利用直接蓝牙连接,创建一个“网状网络”,其中每部手机中继消息,扩展了超出直接范围的覆盖。当互联网可用时,消息会通过去中心化的中继网络路由,确保没有中央数据存储。重要的是,Bitchat不需要帐户、电话号码或SIM卡,优先考虑隐私和可访问性。 经Tech for Palestine (T4P) 验证,Bitchat在面临动荡的地区(如尼泊尔和马达加斯加)越来越受欢迎,这些地区的政府限制了传统的社交媒体。它具有基于位置的“Geohash”频道,用于社区连接和安全检查。鼓励用户通过“/c”命令定期清除消息,以提高安全性。结合Gaza Online的eSIM等服务,Bitchat旨在赋能个人和社区,在一切都失败时保持联系。 在App Store或Google Play下载Bitchat,开始安全通讯。

Bitchat is a new messaging app that allows users to chat securely with or without internet access. Download it today via the App Store or Google Play store to begin communicating safely, even when connectivity disappears.

Why Bitchat is needed

Palestinians are dependent on Israel for their access to electricity, telecoms, and internet routing. Israel has weaponized this dependence in Gaza by deliberately causing blackouts that have left Palestinians cut off from communicating with each other or with the outside world. The relentless bombing campaign has also destroyed or severely crippled any remaining communication infrastructure.

Even when Palestinians use regular communication methods, their conversations and messages can be monitored and recorded, leaving them exposed to surveillance and potential targeting.

The basic human right to communicate freely, and without interruption, has been denied to the Palestinian people.

The solution

Bitchat lets you keep messaging even when the internet or power is down. It connects phones directly through Bluetooth, and each phone helps pass messages along, allowing communication to stretch much farther than just your immediate area. Everything is fully encrypted so your conversations stay private.

When you do have internet or cell service, Bitchat can send your messages anywhere in the world using a network of relays. There is no central server that stores any of your data. You don’t need to create an account, share your phone number or email, or even have a SIM card to use it.

Staying connected when all else fails

Bitchat is an Israel-proof messaging alternative that continues to work even when traditional networks are shut down. The app also has “Geohash” channels that allows users to join location-based chats, so Palestinians can stay connected to their neighbors down the street or to the larger community in cities across the region. 

This lets Palestinians check on the safety of loved ones, organize and coordinate within their communities, and share critical news and updates.

Validated by T4P

T4P has evaluated the app, testing it in various conditions, and looked at the technology and governance of the application. After this evaluation, T4P recognizes it as a secure and resilient communication tool for Palestinian communities when faced with internet disruptions or outages. In addition, Tech for Palestine community members are among BitChat’s top code contributors.

Bitchat has seen a surge in downloads in countries facing civil unrest like Nepal, Indonesia, Côte d'Ivoire, and most recently Madagascar. The Nepali government blocked access to all major social media platforms, forcing civilians to search for alternative methods of communication.

WhatsApp is known to expose private data, potentially to Israel – and these breaches have been used to target Palestinians. Communicating via WhatsApp or social media presents the risk of exposing private data, limiting free expression, and undermining user privacy. BitChat does not have the same vulnerabilities and does not allow Meta to help Israel surveil Palestinians.

Get started

You can start using Bitchat easily, without even creating an account. To start, download the app from the App Store or Google Play store.

Once installed, the first thing you should do is change the default @anon username at the top. Click on it to change. 

The blue #mesh channel in the top right corner will indicate that you are active on your local bluetooth network. Next to it you will see an icon with the number of users connected within your network. Click on the icon and begin private conversations with users from the list.

We recommend confirming your friends’ and family members’ usernames in person when possible. This helps make sure you’re talking to the right people and avoids confusion or impersonation. Once you’ve confirmed someone’s identity, you can start messaging them privately. You can also “favorite” them so they’re easy to find later.

Begin messaging by using the “type a message…” box. Type in a forward slash / to open the menu for additional commands and options.

Locations:

If you click on the blue #mesh channel on the top right it will open the various location channels available.

  • #mesh: The mesh channel is your local bluetooth network that extends as far as the number of connected devices using Bitchat. So the more users with the ability to relay over distance, the larger the network. This is the channel that will allow you to communicate when all other networks are down. 
  • Location channels: You will see default channel names for your block, neighborhood, city, province, and region. These work best when connected to the internet.  
  • #Geohash: the geohash channel is a custom channel that you can start to connect with your immediate family or local groups. Type in a name for your channel and click teleport. Users within your network can then join it. 

Helpful tips:

  • It is encouraged to clear your messages with the command “/c” on a regular basis. This is good practice in the scenario where your phone is confiscated. Messages are only accessible on device as Bitchat has no central servers. If you delete the messages, they aren’t accessible anywhere. 
  • Gaza Online provides renewable eSIMs to restore internet access across Gaza, helping people stay connected and access essential services. Paired with Bitchat, it can help communication continue even when networks are down.

Stay connected, stay safe.
