# Discovery v5
|
||||||
|
## Introduction
|
||||||
|
This `eth/p2p/discoveryv5` directory holds a Nim implementation of the
|
||||||
|
discovery v5 protocol specified
|
||||||
|
[here](https://github.com/ethereum/devp2p/blob/master/discv5/discv5.md).
|
||||||
|
|
||||||
|
This specification is still in DRAFT and thus subject to change. In fact, it is
|
||||||
|
likely that the current packet format will change, see
|
||||||
|
https://github.com/ethereum/devp2p/issues/152.
|
||||||
|
|
||||||
|
This implementation does not support "Topic Advertisement" yet.
|
||||||
|
|
||||||
|
The implementation relies on other modules in the `eth` package, namely: `keys`,
|
||||||
|
`rlp`, `async_utils` and `trie/db`. The latter is likely to change, see
|
||||||
|
https://github.com/status-im/nim-eth/issues/242
|
||||||
|
|
||||||
|
## How to use
|
||||||
|
|
||||||
|
```Nim
|
||||||
|
let
|
||||||
|
rng = keys.newRng
|
||||||
|
privKey = PrivateKey.random(rng[])
|
||||||
|
(ip, tcpPort, udpPort) = setupNat(config) # Or fill in external IP/ports manually
|
||||||
|
ddb = DiscoveryDB.init(newMemoryDB())
|
||||||
|
d = newProtocol(privKey, ddb, ip, tcpPort, udpPort, rng = rng)
|
||||||
|
|
||||||
|
d.open() # Start listening
|
||||||
|
```
|
||||||
|
|
||||||
|
This will initialize the `Protocol` and start listening. However, as no
|
||||||
|
bootstrap nodes were passed in the `newProtocol` call, the created ENR will need
|
||||||
|
to be advertised somehow ("out of band"), so that the node can become known to
|
||||||
|
other nodes in the network.
|
||||||
|
|
||||||
|
To initialize with a bootnode or a set of bootnodes, the ENRs need to be passed
|
||||||
|
as parameter in `newProtocol`.
|
||||||
|
```Nim
|
||||||
|
d = newProtocol(privKey, ddb, ip, tcpPort, udpPort,
|
||||||
|
bootstrapRecords = bootnodes)
|
||||||
|
d.open() # Start listening and add bootstrap nodes to the routing table.
|
||||||
|
```
|
||||||
|
|
||||||
|
Now there are two ways to run the protocol.
|
||||||
|
|
||||||
|
One can call `d.start()` and two loops will be started:
|
||||||
|
1. Random lookup loop
|
||||||
|
2. Revalidation loop
|
||||||
|
|
||||||
|
The first loop will at specific interval do a lookup with a random `NodeId`.
|
||||||
|
This lookup will add discovered nodes to the routing table.
|
||||||
|
The second loop will at random ranged interval send a ping to the least recently
|
||||||
|
seen node in a random bucket. This is to keep the routing table cleared of
|
||||||
|
unreachable/dead nodes.
|
||||||
|
|
||||||
|
Or, one can decide to do this manually within its application by using the
|
||||||
|
available calls:
|
||||||
|
- `lookupRandom` and `lookup` for discovering more peers.
|
||||||
|
- `revalidateNode` or directly `ping` for revalidating nodes.
|
||||||
|
|
||||||
|
In the future, the random lookup loop might be altered to only run in case no
|
||||||
|
lookup was done in the last x minutes. This way `d.start()` could still be run
|
||||||
|
while maintaining control over the lookups.
|
||||||
|
|
||||||
|
Of course, in either scenario, lookups can still be done for actually finding a
|
||||||
|
specific node. There is a `resolve` call that can help with this, it will first
|
||||||
|
look in the local routing table and if it finds the node it will try to contact
|
||||||
|
the node directly to check if the ENR is up to date. If any of this fail a
|
||||||
|
`lookup` will be done.
|
||||||
|
|
||||||
|
## Test suite
|
||||||
|
To run the test suite specifically for discovery v5 related (discovery v5 + its
|
||||||
|
nim-eth dependencies) tests, one can run following command:
|
||||||
|
```sh
|
||||||
|
# Install required modules
|
||||||
|
nimble install
|
||||||
|
# Run only discovery v5 related test suite
|
||||||
|
nimble tests_discv5
|
||||||
|
```
|
||||||
|
|
||||||
|
## dcli
|
||||||
|
This is a small command line application that allows you to run a discovery
|
||||||
|
node. It also has the options to do a `ping` or `findNode` request to a specific
|
||||||
|
node, by providing its ENR.
|
||||||
|
|
||||||
|
### Example usage
|
||||||
|
```sh
|
||||||
|
# Build dcli
|
||||||
|
nim c -d:chronicles_log_level:trace -d:release eth/p2p/discoveryv5/dcli
|
||||||
|
# See all options
|
||||||
|
./eth/p2p/discoveryv5/dcli --help
|
||||||
|
# Ping another node
|
||||||
|
./eth/p2p/discoveryv5/dcli ping enr:<base64 encoding of ENR>
|
||||||
|
# Run discovery node
|
||||||
|
./eth/p2p/discoveryv5/dcli --log-level:debug --bootnode:enr:<base64 encoding of ENR>
|
||||||
|
```
|
||||||
|
|
||||||
|
### Metrics
|
||||||
|
Metrics are available for `routing_table_nodes`, which holds the amount of nodes
|
||||||
|
in the routing table.
|
||||||
|
|
||||||
|
To compile in an HTTP endpoint for accessing the metrics add the `insecure`
|
||||||
|
compile time flag:
|
||||||
|
```sh
|
||||||
|
# Build dcli with metrics
|
||||||
|
nim c -d:insecure -d:chronicles_log_level:trace -d:release eth/p2p/discoveryv5/dcli
|
||||||
|
# Run dcli with metrics
|
||||||
|
./eth/p2p/discoveryv5/dcli --metrics --bootnode:enr:<base64 encoding of ENR>
|
||||||
|
```
|
||||||
|
|
||||||
|
You can now see the metrics at http://localhost:8008/metrics. Or use e.g.
|
||||||
|
Prometheus to grab the data.
