# net2o — reinventing the Internet # net2o is the attempt to reinvent the Internet. It's free software available under the [AGPLv3](https://www.gnu.org/licenses/agpl-3.0.en.html). ## Authors ## Principal author of net2o is * Bernd Paysan ## Get it and try it ## net2o is currently under early alpha test. [Get it](get-it.md) and [try it](try-it.md). There are lots of things [to do](todo.md). ## What's broken? ## * The internet bases on assumptions 20-30 years old * These assumptions are wrong today * Much of it followed the “good enough” principle * There's a huge pile of accumulated cruft * Fixing this mess one-by-one is the wrong attempt ## What for? ## I've a dream: A peer-to-peer network, where services like search engines or social networks aren't offered by big companies, who in turn need to make money by selling the privacy of their users. Where all data is encrypted, so that access is only possible for people who have the key and really are authorized. Which layman can use without cryptic user interfaces. Where the browser is a platform for running useful applications without the mess of Flash and JavaScript. Without the lag of “buffer bloat” and without the speed problems of a protocol not designed to be assisted by hardware. [Richard Stallman on how to fix the surveillance systems](https://www.theguardian.com/commentisfree/2018/apr/03/facebook-abusing-data-law-privacy-big-tech-surveillance) ## What needs to be fixed? ## * IP: Use switch-based simple routing, don't route every packet * TCP: Most data just needs to be obtained reliable, the order doesn't matter. And TCP's flow control is broken (delay minimized is the way to go). * Encryption everywhere: This is no longer an expensive operation (and for symmetric encryption, fast hardware implementation is feasible) * P2P instead of client-server * A new API (render layer, markup language, scripting) — the browser is there for serious applications now. Rendering is done with OpenGL ES, GUI layer is [MINOΣ 2](https://fossil.net2o.de/minos2). net2o has been inspired by Open Network Forth from Heinz Schnitter. ## What third party technology do we use ## * [ed25519](ed25519.md) from Dan Bernstein (in the donna version from floodyberry) * [Keccak](http://keccak.noekeon.org/) (original reference implementation) * [Threefish](https://www.schneier.com/threefish.html) as block cipher in ECB mode and in [Threefish AEAD mode](threefish.md) as backup for Keccak. * ([wurstkessel](wurstkessel.wiki) from myself — now replaced by Keccak) ## Documentation ## The documentation is work in progress. The seven layers of net2o are not equal to the ISO-OSI layers, but this layering provides a familiar starting point: 1. Physical layer — this is not part of net2o itself. 2. [Topology](topology.md) 3. [Encryption](encryption.md) 4. [Flow Control](flow-control.md) 5. [Commands](commands.md) 6. [Distributed Data](distributed-data.wiki) 7.
