Questions about RPC

Open rairyx opened this issue 6 years ago • 4 comments

Regarding the RPC structure https://github.com/libp2p/specs/tree/master/pubsub#Implementations In what case would an RPC message include multiple content messages from multiple sources? How can one know the original sender of the RPC?

Each Message in the RPC includes the peer ID of the peer that sent the message and a signature.

Thanks @Stebalien I want to do some routing based on RPC instead Message before applying floodsub/gossipsub, is it possible? Sometimes the Message doesn't contain from field(omitted by the sender), how to distinguish different messages/RPC in this case?

Yes? I'm not sure what you're asking.

Messages must contain the from field.

@Stebalien

Yes? I'm not sure what you're asking.

I'm wondering if one can relay the RPC message in whole to one random peer before publish the messages inside the RPC one by one to multiple peers as floodsub/gossipsub do.

Messages must contain the from field.

Isn't the from field optional as defined in rpc.proto? In case the sender want to hide its ID.
