The last few weeks we open-sourced the ThingsIX code for the packet-handling on our Github. As ThingsIX is a open project, everyone is welcome to contribute.
We are currently testing packet-handling internally. Soon we will provide instructions how to join the testing of the data-network on testnet. Currently only gateways where users can configure their packet-forwarder endpoints are supported.
Later this year we are planning to launch the data-network (so no rewards yet) in production according to our roadmap.
