The [RPC Interface](./rpc-interface.md) is specified in this repository.
## Identify
**Note: This protocol is a placeholder and will be updated once the discv5
discovery protocol is added to this document**
#### Protocol Id: `/eth/serenity/id/1.0.0`
The Identify protocol (defined in go - [identify-go](https://github.com/ipfs/go-ipfs/blob/master/core/commands/id.go) and rust [rust-identify](https://github.com/libp2p/rust-libp2p/blob/master/protocols/identify/src/lib.rs))
allows a node A to query another node B which information B knows about A. This also includes the addresses B is listening on.
This protocol allows nodes to discover addresses of other nodes to be added to
peer discovery. It further allows nodes to determine the capabilities of all it's connected
peers.
### Configuration Parameters
The protocol has two configurable parameters, which can be used to identify the
type of connecting node. Suggested format:
```
version: `/eth/serenity/1.0.0`
user_agent: <client name and version>
```
## Discovery
**To be updated to incorporate discv5**
Discovery Version 5
([discv5])(https://github.com/ethereum/devp2p/blob/master/discv5/discv5.md)
will be used for discovery. This protocol uses a UDP transport and specifies
its own encryption, ip-discovery and topic advertisement. Therefore, it has no
need to establish establish streams through `multistream-select`, rather, act
as a standalone implementation that feeds discovered peers/topics (ENR-records) as
`multiaddrs` into the libp2p service.
