What is peer and seed in hermes relayer?

Question

Hello, I've been setting up the hermes relayer between my chain and cosmos hub. But I don't know the exact meaning of peer and seed. Please give me some explanations about peer and seed.

We do not use this terminology in Hermes but rather talk about:

• source and destination chain when talking about the relaying flow of a packet
• host and reference chain when talking about IBC clients

May I ask where you have seen mention of peer and seed in relation with Hermes?

In any case, for any pair of chains specified in the configuration, Hermes will relay packets in both directions between the chains.

Hope that helps!

Thank you for your reply. If I am going to run my node, I must give the seeds information to app.toml file. Here I mean seed node and peer node

For starting & operating a full node, you will need to look at network specific documentation. For example, if you want to operate an Osmosis node, start here: https://docs.osmosis.zone. For Evmos, check this out: https://docs.evmos.org/validators/mainnet.html. Each network has their specific details, which include seed node details.

There is also the chain registry, which include publicly-accessible seed nodes for all networks, examples for akash

Thank you for your reply. It helps me a lot but I have some questions. If I set up the relayer between my chain and cosmos hub, do I have to set up the relayer on the machine running my node? and why do I have set the daemon settings?

do I have to set up the relayer on the machine running my node?

Not necessarily, the relayer and your network can be on separate machines.

and why do I have set the daemon settings?

I don't understand, would you mind rephrasing? See also https://docs.osmosis.zone/osmosis-core/relaying/relayer-guide/
