Connect external full node

Protocol exercised: Relay + RLN Relay — attaches an additional logos-delivery node to the simulated network as a full relay participant with its own RLN membership.

If you want to attach a node with some custom configuration to the simulated Logos Delivery network — perhaps a different image, a different RLN epoch length, or any other knob — you can do it as follows. Bear in mind that if this node uses different RLN parameters (e.g. rln-relay-epoch-sec or rln-relay-user-message-limit) than the rest of the network, the gossipsub layer will treat its messages as invalid and you won't see them propagate.

• ⚠️set your own staticnode

docker run -it --network logos-delivery-simulator_simulation wakuorg/nwaku:latest \
      --relay=true \
      --rln-relay=true \
      --rln-relay-dynamic=true \
      --rln-relay-eth-client-address=http://foundry:8545 \
      --rln-relay-eth-contract-address=0xCf7Ed3AccA5a467e9e704C703E8D87F634fB0Fc9 \
      --rln-relay-epoch-sec=1 \
      --rln-relay-user-message-limit=1 \
      --log-level=DEBUG \
      --staticnode=/ip4/10.2.0.16/tcp/60000/p2p/16Uiu2HAmAA99YfoLitSXgY1bHaqjaTKhyrU4M4y3D1rVj1bmcgL8 \
      --pubsub-topic=/waku/2/rs/66/0 \
      --cluster-id=66

You can for example try to connect a node running in a different cluster-id or other weird scenarios.

You can also try to connect multiple nodes with a loop. Note the &. Remember to kill the new nodes once you are done.

for i in {1..5}; do
    docker run -it --network logos-delivery-simulator_simulation wakuorg/nwaku:latest \
      --relay=true \
      --rln-relay=true \
      --rln-relay-dynamic=true \
      --rln-relay-eth-client-address=http://foundry:8545 \
      --rln-relay-eth-contract-address=0xCf7Ed3AccA5a467e9e704C703E8D87F634fB0Fc9 \
      --rln-relay-epoch-sec=1 \
      --rln-relay-user-message-limit=1 \
      --log-level=DEBUG \
      --staticnode=/ip4/10.2.0.16/tcp/60000/p2p/16Uiu2HAmAA99YfoLitSXgY1bHaqjaTKhyrU4M4y3D1rVj1bmcgL8 \

      --cluster-id=66 &
done

🎯Goals:

• Connect a different node(s) to the network for some ad hoc test.
• See how the network reacts to a node with different configuration.

👀Observability:

• Check the new node logs, ensuring the behaviour matches the expected.
