Description

Updates the contract listening and registration process, and inserts rateCommitments into the tree instead of idCommitments

A follow up PR will be created to:

  • accept the arguments into WakuRlnConfig, and allowing wakunode2 to be setup with rln-v2 credentials.
  • incrementing nonce per epoch

Changes

  • adds additional config option --rln-relay-user-message-limit to be set while running the keystore generator, which is included in the key creation in the keyfile
  • inserts rateCommitments into the tree instead of idCommitments

How to test

  1. Build wakunode2 RLN_V2=true make -j16 wakunode2
  2. Register to the membership set
./build/wakunode2 generateRlnKeystore \
--rln-relay-cred-path:./rlnKeystore.json \
--rln-relay-eth-client-address:https://<secret> \
--rln-relay-cred-password:sup3rsecure \
--rln-relay-eth-contract-address:0xABd93f37833107eDbAb58633ad5463aDEa1F95F4 \
--rln-relay-eth-private-key:<secret> \
--rln-relay-user-message-limit:5 \
--execute

which yields the below output:

libbacktrace error: no debugging symbols available. Compile with '--debugger:native'.

This PR may contain changes to configuration options of one of the apps.

If you are introducing a breaking change (i.e. the set of options in latest release would no longer be applicable) make sure the original option is preserved with a deprecation note for 2 following releases before it is actually removed.

Please also make sure the label release-notes is added to make sure any changes to the user interface are properly announced in changelog and release notes.

Nitpick comment: shall we add the units to make it clearer?

Unrelated to this PR but the valueOr and isOkOr result statements are very interesting

I think for further PRs we'd need to tackle all the discard statements that we have in rln code base.

May it be more explicit?

this may cause confusion about converting the rateCommitment into an IDCommitment, when that is not the case. here we have used seq[byte] to discern it from an IDCommitment. I don't see the value in creating a type for it i.e SerializedRateCommitment yet.

lgtm.

Out of curiosity, rlnRelayUserMessageLimit over which epoch size is applied? The default one of 1 sec?
