Is somebody working on a DAG implementation using dgraph?

I came across dgraph recently and I see the value over traditional sql or nosql implementations. Especially the GraphQL style of querying.

Recently the DAG (Directed acyclic graph) as the alternative to blockchains gains popularity because of low transactions fees and fast throughput.

Current implementations like IOTA or Byteball uses rocksdb or mysql as a database layer that adds lots of boilerplate to the code and probably are way slower than dgraph.

I’m wondering if somebody already thought about how to implement a DAG solution based on dgraph.

Not sure if anyone is doing this yet. Happy to help someone if they try implementing a DAG over Dgraph. @ciocan do you what kind of queries are done for a DAG?
