But you have to accept the fact that despite the silence of OP. This is a project that is still active upto some extent. Normally projects who teams are silent never run for long but this project is up and running for almost 2 to 3 years. Even today it has volume of 0.7 million USD, which clearly indicates that its up and running.
If you see timeline of MASS on its website then its very much complete but we haven't heard anything that whether all targets mentioned on timeline are achieved or not? For instance, MASS Cross-chain Development and release of the MASS Cross-chain protocol was expected by June 2020 but we dont know whether its achieved or not.
