Problem
During RLN testing with different network sizes and RLN config, it was noticed that sometimes when there are many consecutive RLN membership registrations occurring and many messages published by other already registered nodes, then some messages in the network are identified as spam.
This happens while the messaging rate is well within the RLN limits and should not lead to any spam messages being identified by the nodes.
Impact
These messages are not spam and should be relayed. This erroneous identification of spam messages could lead to nodes disconnecting from a peer because it seems like it is spamming
To reproduce
Using the waku-simulator https://github.com/waku-org/waku-simulator:
- env. config:
NWAKU_IMAGE=harbor.status.im/wakuorg/nwaku:v0.30.0
NUM_NWAKU_NODES=1
RLN_RELAY_EPOCH_SEC=60
RLN_RELAY_MSG_LIMIT=400
TRAFFIC_DELAY_SECONDS=0
MSG_SIZE_KBYTES=3
MAX_MESSAGE_LIMIT=400
- Run the simulator and wait for the network to stabilise and start publishing messages
- Run this command to register multiple RLN memberships consecutively:
docker run --network waku-simulator_simulation alrevuelta/go-waku-light:4fe5a81 \
--eth-endpoint=http://foundry:8545 \
--contract-address=0xCf7Ed3AccA5a467e9e704C703E8D87F634fB0Fc9 \
register \
--priv-key=ac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 \
--user-message-limit=150 \
--amount=20
- It may be necessary to increase the amount of memberships to register or run the command again.
Expected behavior
These messages should be valid.
