AssetSupportNetwork

The Ravencoin network consists of nodes communicating on port 8767.

There are three networks:
Mainnet which uses a network identifier RAVN
Testnet which uses a network identifier RVNT
RegTest which uses a network identifier CROW

An additional command has been added to the network for asset support. This can be used by SPV nodes to get information about assets without interacting with a centralized API or a Remote Procedure Call.

getassetdata

The following is the specification for this new network call - available starting with network version 70018

Example 1: Request for asset name that doesn't exist

   Request -> getassetdata
