How is MGW planed for the future? Now when some production MGW servers are running, will be there more servers and if the production servers will be offline, the new ones will work seamlessly?
Or if some big player will not trust other servers running 24/7 then he will make some own and will be sure that MGW will never stop working?
As far as I know, the MGW code was built with scalability in mind so it could be made to work with a larger pool of servers. So in theory it is possible, although it would require to be developed. Also, when phasing comes to the Nxt blockchain there will be several possible enhancements. This is why need to find a dev that can put focus on MGW coding in the near future. James is always there for critical interventions, but he will hardly have time to develop MGW.
For the coming production servers, the server specs have improved. Frohike is enhancing security, Anton (server admin working with Coinomat) has added a modification to automatically respawn the MGW daemon in case of software crash, and there's other monitoring features in the to-do list. So there are improvements in the short term, and I hope we'll find the way to have continuous development.
