MeshChain status (operator truth)

Integrity posture (Track A+)

Control	Status
Signed BlockAcks (ed25519)	yes
Leader schedule height % N on apply	yes
Mint external_ref uniqueness	yes
Faucet mints via gossip --peer	yes (set MESH_MINT_PEER)
Producers reject untrusted SyncResponse	yes
Block-by-block catch-up (BlocksRequest)	yes
Atomic chain_state.json writes	yes
Append-only block archive data/blocks/{h}.json	yes
Equivocation detect (same height, two hashes)	yes
Mempool dry-run against state	yes
Gossip line size + per-peer rate limit	yes
Multi-tx blocks (≤16)	yes
protocol_version in genesis / Hello	yes (v1)
Faucet daily + global rate caps	yes

Known limitations

1. PoA, not open consensus — seats are coordinator-approved; restack may wipe state.
2. Public finality is TCP PoA — Meshtastic air path is first-class for submit + tip + relay; cloud seed still finalizes on TCP. Full LoRa-only validator set is next.
3. Faucet is a hot minter — capped, not a treasury; testnet only (needs internet).
4. Solana hybrid vault — experimental on devnet; not mainnet-ready (needs internet).
5. Short ids are 8 bytes — full pubkey always bound on register.
6. No on-chain validator governance — mesh genesis-extend + restack for set changes.

Deploy checklist (seed)

cargo build -p mesh -p meshchain-node --release
# install binary + faucet_server.py on host
export MESH_MINT_PEER=127.0.0.1:9100
# unset MESH_ALLOW_OFFLINE_MINT on public hosts
systemctl restart meshchain-testnet   # or host equivalent
./scripts/status_public_seed.sh

Ops: live smoke / observer / archive

# 1) Public e2e (join → wallet → faucet → balance)
./scripts/test_public_e2e.sh

# 2) External observer (any machine)
mesh join-public
meshchain-node run --data-dir ./data --observer \
  --listen 0.0.0.0:9110 --peer 34.172.103.125:9100

# 3) Merge block archives + tip checkpoint (on seed host data dir)
./scripts/backfill_block_archive.sh /opt/meshchain/data/host
# → data/.../blocks/MANIFEST.json + checkpoints/tip.json
# Full blocks only exist from archive_first (post-integrity deploy).
# Earlier heights: applied[] hashes only; observers use SyncResponse.
