SN2 will be a pure decentralized mobile app for small and medium groups. Its first version will provide a messenger, a public key infrastructure (certificate creation and exchange), point-to-point and end-to-end security (encryption and signing). Version 1 will solely be based on Bluetooth communication.

We work on a currency system which is not even based on P2P networks but purely on Ad-hoc networks. (Cannot work? Of course it can. We do since Bronze Age.

SN2 will be a proof of concept. It proofs that mobile apps can work even with total loss (or deliberate avoidance) of Internet access. We see three primary fields:

• Localized games in short range networks
• Apps for search and rescue scenarios in regions with loss of Internet access
• Groups with highest security needs. SN2 gives full control over used networks. In its most paranoid version – SN2 will not use Internet and will not leave any trace.

SN2 is (still) mostly used as test field for other related software components, which are

• ASAPJava (Basis of the Ad-hoc communication features and cryptography)
• ASAPAndroid (Layer 2 (point-to-point) connections for Java, e.g. Bluetooth)
• ASAPCertificateExchange (decentralized PKI based on ASAP)
• MakanJava (messenger application logic based on ASAP)
• ASAP currency (comming soon - hopefully)

This project glues all components together for testing and for demonstration purposes. Peer-to-peer (P2P) is not the last step of decentralization. SN2 / ASAP is.

SN2 is a pure non-profit project. Most work is done at HTW Berlin. Don't hesitate to contact me.

While the technical basis became quite stable, we are still in pre-releases with SN2. The release and test plan is more or less for internal use - but feel free to have a look. Features and usage will be explained on this page as soon as release 1 ist out.

You are welcome to join. Contact me. There is also a short summary of steps how to add a new component to SN2.
