By what they (the MACH Alliance) term it I guess it's all the right letters and they are in some order, but really it's a database with a GraphQL API, an integration layer, some orchestration and another GraphQL layer. But the big thing is it's domain specific and in the end most MACH are just distributed monoliths.
There's no magic frontend either.
