Jack Dorsie It doesn’t waste time. After his departure from Bluesky in 2024, Twitter Co -founder resumed the idea Decentralized and safe messaging systemThe field, unlike its previous initiatives, a new experiment called The essence It is based on Bluetooth and does not require the Internet to work.
In the publication of his account, Jack Dorsie describes the essence as “A weekend project to find out about Bluetooth networks, relay and storage and shipping models, message encryption models and some other things“
In general, Bitchat is a P2P application based on Bluetooth This does not need the Internet, or servers or telephone numbers. “Only pure and encrypted communication“Dorsie mentions the GitHub project on the web.
Susk is compatible with the iPhone and Mac, so users can Send ephemeral messages to other people and gain access to chatsThe field since the application does not require a phone or email number to use it, there is no need to create an account. All messages are encrypted and exist only in the memory of the device, so they are removed when they leave the application.
In terms of security, Bitchat offers End -ed encryption with keys X25519 + AES-256-GCM in private messages. The rooms use the ARGON2ID + AES-256-GCM password production, so participants can communicate with confidence. Dorsy mentions other additional encryption functions, such as the digital signatures of the Ed25519 to check the authenticity of the message and keys to the keys generated in each session.
How Bitchat works, the new “WhatsApp” Jack Dorsy, who does not need the Internet
One of the most striking characteristics of this experiment is that he does not need Internet or servers to work. The bitch is based on Decentralized net network that transfers messages via BluetoothField
Bickat decides the need for safe and private communication, which does not depend on the centralized infrastructure. Using the advantages of the Bluetooth grid with low consumption, Bitchat allows a direct exchange of messages in physical proximity, with automatic messages that expand the effective area outside the Bluetooth direct connections.
According to the technical document, Suzuka implements Personalized protocol on BluetoothA field in this grid each device acts as a client and peripheral devices, which allows Transmit messages through a few jumpsThis means that if the user is far from the user C, but B is one of them, the messages will move from A -> B -> C.
The application uses local clusters formed by users They are in the range of 30 meters. The architecture connects these clusters through Bridge nodesAllowing messages to jump over the network and achieve devices that are outside the range. If you send a message, and the person is disconnected, The message will be stored in the cache And it will be sent when it connects again.
Because all communication is carried out between nearby devices that make up the grid, Switch does not need servers or accountsThe message field uses the compression of LZ4, which will retain the bandwidth of up to 70%. Jack Dorsie mentioned that he was planning to launch Hybrid version with Wi -fi Direct supportWhat will increase the volume and throughput, as well as other improvements to guarantee that the messages have reached their destination, even if the network is saturated.
The current version SUSKA can be checked using TestFlight in iOS and MacOSThe field at the moment is not a version of Android, although Dorsy notes that the protocol is intended to be independent of the platform.
