Chat-side integration of the LEZ-backed RLN mix protocol:
- src/chat/delivery/waku_client.nim: mount waku_mix with onchain
RLN spam protection wired to logos_core_client fetchers; gate
the first publish on (a) gifter status confirmation, (b)
cushion of 2 poll intervals after confirmation, and (c) proof
root stability in the local valid_roots window; wrap mix
lightpush in withTimeout so vanished SURB replies surface as
Err instead of pinning the send coroutine.
- src/chat/client.nim: surface sendBytes errors via asyncSpawn
wrapped try/except instead of discarding the future (was
hiding every mix-publish failure).
- chat-side gifter client invocation (RLN membership service
wire format, EIP-191 ethereum-allowlist auth).
- Background membership status watcher that reconciles the
optimistic leaf returned by the gifter against the chain's
authoritative leaf via the status RPC.
Simulation harness (simulations/mix_lez_chat/):
- Spin up sequencer + run_setup + 4 mix nodes (one of which
runs the gifter service) + chat sender + chat receiver.
- SIM_NETWORK={local,testnet}, SIM_SLIM for testnet (reuses
shipped config_account + cached payment_account), Docker
image + GHCR for cross-platform testing.
- Strict mix-pool readiness gate, kademlia + RLN root activity
checks, gifter EIP-191 auth fixture, slim-mode submodule
minimization.
- TREE_ID_HEX pinned to the canonical testnet deployment.
Submodule bumps:
- vendor/nwaku to 8e6ba04 (LEZ-backed RLN mix + 2-phase gifter).
- vendor/logos-lez-rln to 950f287 (SPEL RLN program + mix sim
infrastructure + canonical testnet deploy).

- RUN_SLIM_TESTNET.md: slim sim recipe.
- cleanup/MODE_A_GIFTER_SLOT_BUG.md: per-signer nonce collision
postmortem driving the queue+worker fix.

# Slim sim against latest testnet deployment
|
|
|
|
```bash
|
|
git clone -b feat/sim-rln-gifter-auth-v2 git@github.com:logos-messaging/logos-chat.git
|
|
cd logos-chat && git submodule update --init --recursive
|
|
SIM_NETWORK=testnet SIM_SLIM=1 SIM_DELIVERY_TIMEOUT=1800 \
|
|
bash simulations/mix_lez_chat/run_simulation.sh --fresh
|
|
```
|
|
|
|
~15-25 min depending on testnet block timing. Pass: **ALL 15 CHECKS PASSED**.
|
|
|
|
Slim mode reuses the on-chain RLN programs at the shipped `TREE_ID` (committed in `vendor/logos-lez-rln/testnet/`) — no fresh deploy. The shipped payment account holds 1B RLNTOK (~1000 registrations) drawn from a 10B supply, refilled by re-running `vendor/logos-lez-rln/lez-rln/target/debug/run_setup` against testnet when needed.
|
|
|
|
`SIM_DELIVERY_TIMEOUT=1800` (30 min) is required: the gifter now serializes registrations through a single-writer worker that awaits chain confirmation between submissions to avoid per-signer nonce collisions. With testnet's ~60-90 s block cadence and up to ~6 jobs ahead in the queue, the chat sender (last in line) needs the longer delivery window. The default 300 s value would expire before its registration confirms.
|
|
|
|
If a run still fails after a clean retry: the most likely cause is a stale `~/.logos-lez-rln/payment_account_<TREE_ID>.txt` cache from a previous shipped TREE_ID. Wipe with:
|
|
|
|
```bash
|
|
rm -f ~/.logos-lez-rln/payment_account_*.txt \
|
|
~/.logos-lez-rln/supply_holding_*.txt \
|
|
vendor/logos-lez-rln/testnet/storage.json \
|
|
vendor/logos-lez-rln/testnet/wallet_config.json
|
|
```
|
|
|
|
and re-run — `seed_copy` will then re-seed from the shipped sidecars.
|
|
|
|
If you haven't built the modules on this machine before, run `bash simulations/mix_lez_chat/setup_and_run.sh` once first to build the dylibs.
