# Portal Network Wire Protocol
|
|
## Introduction
|
|
The `fluffy/network/wire` directory holds a Nim implementation of the
|
|
[Portal Network Wire Protocol](https://github.com/ethereum/portal-network-specs/blob/master/state-network.md#wire-protocol).
|
|
|
|
The wire protocol builds on top of the Node Discovery v5.1 protocol its
|
|
`talkreq` and `talkresp` messages.
|
|
|
|
For further information on the Nim implementation of the Node Discovery v5.1
|
|
protocol check out the
|
|
[discv5](https://github.com/status-im/nim-eth/blob/master/doc/discv5.md) page.
|
|
|
|
## Test suite
|
|
To run the test suite specifically for the Portal wire protocol, run following
|
|
commands:
|
|
```sh
|
|
git clone git@github.com:status-im/nimbus-eth1.git
|
|
cd nimbus-eth1
|
|
|
|
# To bring the git submodules up to date
|
|
make update
|
|
|
|
# Build & run Portal wire protocol encoding test
|
|
./env.sh nim c -r ./fluffy/tests/test_portal_wire_encoding
|
|
# Build & run Portal wire protocol network test
|
|
./env.sh nim c -r ./fluffy/tests/test_portal_wire_protocol
|
|
```
|
|
|
|
## portalcli
|
|
This is a small command line application that allows you to run a node running
|
|
Discovery v5.1 + Portal wire protocol.
|
|
|
|
*Note:* Its objective is only to test the protocol wire component, not to actually
|
|
serve content. This means it will always return empty lists on content requests
|
|
currently. Perhaps in the future some hardcoded data could added and/or maybe
|
|
some test vectors can be created in such form.
|
|
|
|
The `portalcli` application allows you to either run a node, or to specifically
|
|
send one of the Portal message types, wait for the response, and then shut down.
|
|
|
|
### Example usage
|
|
```sh
|
|
git clone git@github.com:status-im/nimbus-eth1.git
|
|
cd nimbus-eth1
|
|
|
|
# Build the fluffy tools
|
|
make fluffy-tools
|
|
|
|
# See all options
|
|
./build/portalcli --help
|
|
# Example command: Ping another node
|
|
./build/portalcli ping enr:<base64 encoding of ENR>
|
|
# Example command: Run a discovery + portal node
|
|
./build/portalcli --log-level:debug --bootstrap-node:enr:<base64 encoding of ENR>
|
|
```
