# Supported subset will eventually be found here:
# https://github.com/ethereum/stateless-ethereum-specs/blob/master/portal-network.md#json-rpc-api
#
# In order to already support these calls before every part of the Portal
# Network is up, one plan is to get the data directly from an external client
# through RPC calls. Practically just playing a proxy to that client.
# Can be done by just forwarding the rpc call, or by adding a call here, but
# that would introduce a unnecessary serializing/deserializing step.
