UniverseRPC - RPC standard that allows communication with all cosmos-sdk based chains

[adrianbrink]

The UniverseRPC should be a standard RPC that exposes common functionality of all cosmos-sdk based chains. It is a module that serves the RPC endpoints over Tendermint RPC. A request is made against the UniverseRPC server, which then forwards it to Tendermint RPC, which then goes back into the UniverseRPC module through the query calls.

One of the great advantages of Ethereum with Web3 is that no matter which application logic (smart contract) the same RPC endpoints still work.

Let's have a discussion around UniverseRPC and how we can enable developers to build against a common RPC interface and then be able to deploy that code against any chain that implements it.

The currently exposed routes: https://github.com/tendermint/tendermint/blob/master/rpc/core/routes.go

The idea is that UniverseRPC would provide extra functionality on top of that which is general to every application.
Ideally, almost no one should interact with Tendermint RPC directly, but rather build on top of UniverseRPC.

We need to consider how it works with the light-client.
