It will be based on following principles:
1. Does not support scripting on core level. New transaction types are supported through plug-in system and soft forks. Decentralized contracts might be realized in future based on "proof of execution" and supernodes approach.
2. POS consensus. Improvements to counter the "nothing-at-stake" argument will be considered, but plain-vanilla POS is deemed to be "secure enough"
3. Main focus is on usability and connection to "real world" economy
- At launch fiat and BTC assets are supported. Fiat assets are backed by existing fiat payment systems/banks.
- Asset to asset swap/trading is supported on the core level, which allows to offer quasi stock exchange user experience, with trading against fiat currencies.
- User-friendly interface resembling online banking or online broker interfaces. Realized as a browser plugin.
Basically users have a full-scale crowdfunding/trading platform right at launch, with native fiat currencies support. User experience is close to usual financial website experience.
4. Reputation system is considered to be vital, and will be realized soon after the launch. It will be based on voting system which is an integral part of the core. Also account activity will be used to define the account karma (issued assets, transactions volume etc).
5. Scalability is considered to be the main problem which will need to be tackled eventually, and some basic scalability improvements will have to be made on the core level right from the start.
6. Strict development practices. All major changes in the core should be approved by the stakers community through voting.
7. The client will be coded in low-level programming language (C/C++)
All in all the network has a "NXT Classic" feel, with improved user-friendliness, strict development practices, connection to existing fiat networks, and high-load ready.
1) JL777, after the seperation of SuperNET and NXT after a disagreement about "Backward Compatibility", is currently building a Chrome App which will have asset/BTC pairs. These will be atomic swaps.
