integrated rln DoS protection into mix and ran basic scenarios successfully by chaitanyaprem · Pull Request #3693 · logos-messaging/logos-delivery

chaitanyaprem · 2026-01-23T05:48:41Z

Description

Still a work in progress.
This integrates RLN as spam protection mechanism to be used for mix.
As of now it uses OffChainGroupManager and logos-messaging for broadcasting membership changes and general coordination.
Rate limit is currently set to 100msgs per 10secs per node (any mix node).

Note that i don't want to merge this until we integrate RLN membership management with a smart contract in Logos blockchain is merged.

Dependency

This branch carries the extended kademlia discovery integration as one of its commits (cherry-picked from the original pre-rebase tip). That kademlia work is being delivered separately in #3850 (feat: kademlia discovery). Merge plan: this PR should not be merged until #3850 is merged + tested on master, after which this branch will be rebased on top of master and the duplicate kademlia content dropped.

@Ivansete-status i have noticed that these topic handles are called one after the other.
I don't see any reason to not call them concurrently which might make relay message local processing faster.

Bundles: - Extended kademlia discovery integration for mix node pool (waku/discovery/waku_kademlia.nim, tools/confutils/cli_args.nim) - RLN spam protection plugin (vacp2p/mix-rln-spam-protection) wired in: WakuMix gains mixRlnSpamProtection + publishMessage callback, per-hop proof generation / verification, membership coordination via /mix/rln/metadata/v1 content topic - chat2mix sim app: filter-subscribes to spam-protection coordination topic, defers publishing until mix node pool is populated - Makefile: automated librln_mix_v2.0.0.a build via scripts/build_rln_mix.sh and mix-librln target - simulations/mixnet: 5-node mixnet sim infrastructure (config1-4.toml, run_*.sh, build_setup.sh, setup_credentials.nim, README, roundtrip_check.sh automated round-trip verification) Rebase fixes: - Plugin previously vendored as submodule; now a nimble requires entry pinned to logos-co/mix-rln-spam-protection-plugin@037f8e10 - waku.nimble: zlib < 0.2 pin to keep nimble lock resolution stable (upstream zlib HEAD bumped to 0.2.0) - apps/chat2mix/config_chat2mix.nim: replace `defaultValue: parseIpAddress("...")` with IpAddress literal, works around confutils macro generating `defaultValueHelpName(): string {.raises: [].}` that violates the raises pragma when stringifying a parseIpAddress call - config.nims: nimble setup --noNimblePath reordering Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

… retry WakuMix.start() previously ran a single sequential pipeline that ended with mixRlnSpamProtection.registerSelf() — which publishes the new member's idCommitment to other mix nodes via relay. With master's flow (switch.start() then reconnectRelayPeers() then ...), running registerSelf inline would either: - block startup for ~62s when reconnectRelayPeers backs off, or - run before relay peers exist and silently no-op. Split the start() proc into: - method start*(WakuMix): local-only init (cred load, tree restore, plugin start). Safe to await before peers are connected. - proc registerDoSProtectionWithNetwork*(WakuMix): kick off a background task that retries registerSelf + saveTree indefinitely until the broadcast lands. Cancelled when WakuMix.stop() is invoked. waku_node.start() now wires these in order: switch.start() wakuMix.start() # local init, errors propagate reconnectRelayPeers() # may back off; no longer blocks mix wakuMix.registerDoSProtectionWithNetwork() # fire-and-forget retry node.started = true Re-call safety: registerDoSProtectionWithNetwork no-ops if a prior task is still running. Lifecycle: WakuMix.stop() cancelAndWait()s the task before calling plugin.stop(). For keystore-loaded nodes the first attempt early-returns successfully (membershipIndex already set); the retry path only exercises for fresh joins where the initial broadcast hits a not-yet-subscribed network.
