How does it work?

Fully decentralized peer-to-peer network

The whole BitDust network consists of equal nodes, every device acts as a client and server for others at same time. The user authorizes in the network by himself and safely interacts with others using his ID and a secret key.

Distributed Data Storage

Each BitDust network participant have a chance to allocate his data on machines of other users - his suppliers. Uploaded data are backed up and organized into RAID array for ensuring possibility of reliable recovery.

Automatic Data Recovery

Each supplier gets a double portion of information: the data themselves in encrypted form and RAID-copy, which enables recovery by data loss. The whole process is done automatically and does not need any action from the user.

User Information Protection

All service packets are digitaly signed and personal user data is also encrypted with one of his secret keys – suppliers do not have access to your data. Only with a correct private key you can restore the uploaded data.

Anonymous Network Log-On

For network log on you do not need to pass through any authorization, provide your email or phone number to someone. There is no support team or call center or "head" office. BitDust contributors are just enthusiasts, they are not running "centralized" user information acquisition or some kind of users accounting on the network.

Uses Distributed Hash-Table

Distributed hash-table is used for service information storage, connection between users and maintenance of the network as a whole.

Transmits Data by TCP and UDP

Nodes in the BitDust network are connected to each other directly and data are transmitted using the protocols TCP and UDP.

Users Connections beyond NAT

There are situations when network connection between nodes which are behind NAT cannot be established - receive direct incoming connections in regular manner is not possible. In those cases a distributed hash-table for service information storage is used, similar to rendezvous-point principle other nodes will help you to connect to the network.

Managed by Finite State Machines

BitDust project is developed based on principles of automata-based programming and open project documentation. This is a programming paradigm in which a program or its fragment is represented as a model of some finite state machine.
