In the hyperconnection world we live in, the majority of messaging applications rely on the Internet, central servers, and businesses that control how messages are sent. That means your privacy is invalid.
However, as explained by Cryptonoticia, the Bitcoiner ecosystem has several variants that allow messages and communication without those requirements.
The recently released option is Bitchat. It was conceived by Jack Dorsey, a Twitter Co -Founder (now X), and raises another alternative. Open source apps (P2P) that work from individual to person, No internet connection is required and you can send Bitcoin (BTC).
Bitchat is currently available on Apple devices, and according to Dorsey, it will soon be Android.
After downloading the application, a simple chat interface will open directly so you can see below.
Click the “#meh” option (upper right) to search for close contacts classified by distance (Location Channel): From the block, it passes through everything It has a neighborhood, city, region, and even a radius of 1,250 km.
Why should I use Vichat?
You should use Bitchat because you get the following benefits:
Bichat offer Intermediate Privacy and Independence. This application does not require any information such as email or phone numbers. This reduces fingerprints and limits the possibility of governments and businesses accessing communications.
The cryptocurrency ecosystem has many examples of centralization, including Tether’s ability to freeze USDT transactions. Bichat I’ll leave that logic It coincides with the principles that promoted the creation of Bitcoin, decentralization, resistance to censorship, and freedom of pairs.
- Vichat is internet-independent:
If you are at a festival without a traffic light, in a rural area, or in the middle of a blackout, You can continue to connect to Bitchat. Critical situations such as war, natural disasters, network reduction or protest contexts, or low authoritarian regimes, are scenarios where applications can be even more useful.
For example, in April 2025, an electric power outage affected Spain, France and Portugal, leaving thousands of people in communicado. So, if Bitchat could have maintained the connection.
In addition to chat, the application includes the ability to connect with other nearby bitcoiners and send BTC directly. In the meantime there are no banks or payment processors. Only the Bitcoin network, its nodes and miners were distributed.
The ability to send BTC arises from the possibility of creating and signing Bitcoin transactions off-linethe mesh network extends until it reaches a node connected to the network. To generate transactions, you need a Bitcoin wallet that is compatible with Bittat.
Signed transactions are packaged as messages in formats that are read on the Bitcoin network (usually hexadecimal). Bitchat uses a messaging protocol to encapsulate this data. Ensure that it is compatible with Bluetooth mesh networks Until you reach a node connected to Bitcoin.
This option is especially useful for merchants who can receive payments without relying on centralized intermediaries. If Bitchat integrates Lightning Network (LN) networks in the future, they will pay for them. They may be even faster and have lower transaction costs.
- Mesh networks that extend the Bluetooth range:
Bitchat is based on a Bluetooth mesh network (Bluetooth mesh network English) and the system Devices connect directly to each other to broadcast data.
That means communication occurs between nearby devices or through intermediate nodes. No connection to central infrastructure required Ideal for rural environments and emergencies, such as the web or mobile network.
Bitchat allows you to “jump” messages from devices on your device. The device will expand to about 300 meters, or more if there are enough link users.
The application was created by developers Jack Dorsey and Callebtc. Strengthening the direction of technology autonomy; It is related to Cypherpunk ideology.
How does Vichat work?
Technical operations combine several layers. The first is a Bluetooth mesh network based on Bluetooth Low Energy (BLE) technology. Each device acts as a node that connects to nearby devices.
If you want to send a message to someone from a direct reach, the system uses multiple jump mechanisms (Multi-hop)): Your message Passing through other nodes until you reach your destination. This logic remembers traditional emails where letters pass through several offices and reach the final recipient.
in parallel, Bitchat offers options to use Oursa functioning distributed communication protocol relay (Resender) It was distributed online.
This way, the application can operate in two modes: No connection via NOSTR using local Bluetooth or global connection.
To ensure privacy, applications use noise protocols. Messages can only be read by those who send and receive them.
Not requesting a personal identifier increases anonymity. However, Bitchat makes it clear that the private messaging protocol has not yet passed an external security audit. Possible vulnerability becomes clear.
Among the technical optimizations is message compression using a technique called LZ4. The size of the data sent will be reducedand extends the autonomy of the device with an adaptive battery mode that adjusts energy consumption according to use.
In short, the vichats combine Bitcoin decentralization with practical design for daily messaging. You can maintain private communication without relying on the Internet, while also embedding BTC transmissions into an environment that reflects the values that have created cryptocurrency.
