🤝 Anti-censorship and anti-surveillance communication protocol
Introduction
Berty is an anonymous, secure, peer-to-peer protocol that doesn’t need an internet connection to function.
There is a protocol that uses advanced cryptography and a messenger app that is built on top of the protocol.
- No phone number or email required to create an account
- End-to-end encryption used to encrypt all conversations
- Focus on leaking as little metadata as possible
- Decentralized, distributed, serverless
- No concensus, no blockchain
- No internet connection required (uses the BLE technology and mDNS)
- Free forever, no data stored, transparent code, open-source
Berty is currently developed by Berty Technologies, a French non-profit organization.
Usages:
- When you need to share sensitive information.
- If you want to communicate with good anonymity.
- If you don’t want to use servers, because you want full control of your data.
- In countries that have censorship and restrict network access and usage.
- In areas with weak or no connection or cell reception.
- When you travel and you want to communicate safely through insecure public connections.
Note: the project is made by a small team of humans who are not experts and who make mistakes. Please, do not hesitate to point out if you notice a bug or something missing. See the contribute section below.
We cannot promise to give you the best app, but we can commit to doing our best in that direction.
Development Status
Berty is still under active development and should not be used to exchange important data.
The current Berty Messenger implementation is not using the Berty Protocol yet, but OrbitDB directly. Which means the encryption is not safe, but the good news is that the current Berty Messenger app is already a P2P one!
The current Berty Protocol is partially implemented. The API will certainly change in a near future, so be prepared to have breaking changes if you start using it right now.
We will open betas for the different packages and apps soon, so anyone will be able to give it a try even without the coding skills. Subscribe to our newsletter if you want to be notified.
Note: this is an ongoing work. The repos are being opened progressively, and there will be more changes and updates.
Berty Protocol
A generic SDK that allows developers to write P2P applications. It contains everything needed (encryption, identities, network routing, group management, account management, device management, application lifecycle) so you can just focus on the high-level features of your app.
The main concept of the Berty Protocol is the “group”, a virtual place where multiple devices can share messages and metadata using OrbitDB , which itself relies on IPFS .
Get it: go get -u berty.tech/berty/v2
Berty Messenger
A messenger application written in React Native , that uses the Berty Protocol using gomobile-ipfs , which, in its turn, is using gomobile .
Main items in the repo
- ./go : Where all the Golang code belongs.
- ./go/pkg/bertyprotocol : Berty Protocol Golang SDK to create secure and autonomous groups using IPFS.
- ./go/framework/bertybridge : gomobile entrypoint.
- ./go/cmd/berty : Main Berty CLI, containing:
berty daemon: Runs the whole Berty Protocol instance.berty demo: Development/debugging subcommand which aims to show the internal features more easily.berty mini: Simple CLI messenger app using Berty Protocol.
- ./go/cmd/rdvp : A Rendez-Vous Point server.
- ./js : Where all the Javascript/Typescript code belongs, containing:
- The Berty Messenger application, written in React Native.
- ./docs : Mostly auto-generated documentation.
Philosophy
We want to contribute to the world of free, secure communication without fear of censorship and surveillance.
Open source is more secure, since anyone can examine the code, improve it and maintain it. Our ultimate goal is to completely lose control of Berty and have it evolve as a global community project.
Contributing
