- waku/waku_mix/protocol.nim: drop the magic-2 cover-traffic fallback
and the hardcoded 10s epoch. Source cover-traffic totalSlots and
epochDuration from spamProtectionConfig when RLN is on (so cover
emission can't outpace proof minting), and from named waku
constants (WakuCoverTrafficTotalSlots=40, WakuCoverTrafficEpochDuration=60s,
~10 emissions/min/node) when RLN is disabled. Single ConstantRate
CoverTraffic.new call site at the end of the block; the if/else
only sets up spam protection. Addresses PR review comment on
protocol.nim line 102.
- waku.nimble: bump mix-rln plugin to 8ec5dc24 (latest on
feat/cover-traffic-epoch-support: messageId guard + drift-corrected
epoch timer) and pin nim-lsquic to #6d2bc489 (v0.2.0) so libp2p
1.15.3's certificate_ffi keeps finding EVP_PKEY in lsquic_ffi.nim.
- waku/common/option_shims: explain in a header comment that the file
exists because libp2p 1.15.3 dropped Option[T] overloads of
valueOr/withValue from libp2p/utility; can be removed once those are
restored upstream. Addresses PR review comment.
- simulations/mixnet/setup_credentials: drop the unused
SpammerUserMessageLimit constant (the "Higher" comment was wrong
since 3 < DefaultUserMessageLimit=4, and zerokit blocks proof-gen
past the per-user limit anyway, so it could never simulate a
spammer). Addresses PR review comment.
- simulations/mixnet/run_chat_mix{,1}.sh: pass --rln-user-message-limit=4
so the chat client's RLN budget matches the keystores baked at
limit=4, otherwise cover-traffic totalSlots vs RLN-budget mismatch
jams the sim.
Sim verified end-to-end:
- RLN-on (default sim config): PASS, ≥2 proof-verified per node,
cover-traffic metrics non-zero.
- RLN-off (mix nodes only, ad-hoc config): cover-traffic emits at
~13/min/node from the new waku defaults (target ~10/min); the
no-RLN code path is exercised correctly.
* update rendezvous to work with WakuPeeRecord and use libp2p updated version
* split rendezvous client and service implementation
* mount rendezvous client by default
