Portal master accumulator was removed from the network specs as a content type shared on the network, as since the merge this is a finite accumulator (pre-merge only). So in this PR the accumulator gets removed as network type and gets instead baked into the library. Building it is done by seperate tooling (eth_data_exporter). Because of this a lot of extra code can be removed that was located in history_network, content_db, portal_protocol, etc. Also removed to option to build the accumulator at start-up of fluffy as this takes several minutes making it not viable. It can still be loaded from a provided file however. The ssz accumulator file is for now stored in the recently created portal-spec-tests repository.
Portal Network Wire Protocol
Introduction
The fluffy/network/wire
directory holds a Nim implementation of the
Portal Network 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 page.
Test suite
To run the test suite specifically for the Portal wire protocol, run following commands:
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
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>
