It assumes the first public testnet +uses validators with stable public IP addresses or public DNS names. + +Kora is pre-alpha software. Treat this as a testnet procedure, not a production +mainnet security guide. + +## Overview + +The local devnet starts four validators in one Docker Compose network. That +works because the generated peer file can use Docker hostnames such as +`node0:30303`. A public testnet needs the same artifacts, but the peer file must +use addresses that every validator can dial from the public internet. + +For the first public testnet: + +- Every validator operator provides a stable P2P endpoint, preferably DNS such + as `validator-0.testnet.kora.network:30303`, or a static public IP such as + `203.0.113.10:30303`. +- Every validator opens the P2P port on that endpoint. +- All validators use the same finalized `peers.json`. +- Validators run the interactive DKG ceremony before starting consensus. + +Future iterations can document a private validator mesh using ZeroTier or a +similar VPN. A later P2P design could also explore iroh. Those are follow-up +designs and should not block the public-IP standup path described here. + +## Current Devnet Primitives + +The public testnet flow reuses the existing commands and files: + +- `keygen setup` generates `genesis.json`, `peers.json`, per-validator + `validator.key` files, and optional secondary identities. +- `kora dkg --peers ` runs the interactive DKG ceremony and writes + `share.key` and `output.json` into each validator data directory. +- `kora validator --peers ` starts a validator after DKG has + completed. +- `genesis.json` contains chain state only. It does not contain P2P endpoints. +- `peers.json` contains `participants`, `secondary_participants`, `threshold`, + and `bootstrappers`. + +The important difference from the Docker devnet is the `bootstrappers` section +in `peers.json`. `keygen setup` currently writes Docker-local addresses like +`node0:30303`; for a public testnet, replace them with public DNS names or +public IP addresses before running DKG. + +## Prerequisites + +Choose and record these values before generating artifacts: + +- Validator count, for example `4`. +- Threshold, for example `3` for a 4-validator testnet. +- Chain ID, for example a testnet-specific value distinct from local devnets. +- Public P2P endpoint for each validator. +- Optional secondary peer count. +- A shared release artifact or Docker image version that all validators will + run. + +Each validator host should have: + +- A static public IP address or stable DNS record. +- Inbound TCP open for the Kora P2P port, default `30303`. +- Outbound TCP allowed to every other validator P2P endpoint. +- NTP or another reliable clock sync service. +- Persistent disk for the Kora data directory. +- Log collection and a restart supervisor such as systemd, Docker restart + policy, or equivalent. + +RPC is currently started by the validator command on `0.0.0.0:8545`. Do not +leave RPC open to the internet unless that is an intentional testnet policy. +Prefer firewalling RPC to operator IPs, a bastion, or a public load balancer +that you explicitly control. + +## Address Handling + +Use public DNS names when possible: + +```text +validator-0.testnet.kora.network:30303 +validator-1.testnet.kora.network:30303 +validator-2.testnet.kora.network:30303 +validator-3.testnet.kora.network:30303 +``` + +Static public IPs are also valid: + +```text +203.0.113.10:30303 +203.0.113.11:30303 +203.0.113.12:30303 +203.0.113.13:30303 +``` + +The address in `peers.json` must be the address other validators can dial.

The public endpoint belongs in `peers.json`. +If a host is behind NAT, the public `host:port` must forward to the local Kora +P2P listener. + +## Artifact Layout + +Use one coordinator directory while preparing the network: + +```text +testnet-artifacts/ + genesis.json + peers.json + node0/ + validator.key + setup.json + node1/ + validator.key + setup.json + node2/ + validator.key + setup.json + node3/ + validator.key + setup.json + secondary0/ + validator.key + setup.json +``` + +After DKG, each validator directory also contains: + +```text +share.key +output.json +``` + +Artifact ownership: + +- Share `genesis.json` with every validator and secondary operator. +- Share the finalized `peers.json` with every validator and secondary operator. +- Give each validator operator only its own `nodeN/validator.key`. +- After DKG, keep each `nodeN/share.key` private to that validator. +- `output.json` is required for the validator to start and should be kept with + that validator's data directory. +- Do not publish `validator.key` or `share.key`. + +The current `keygen setup` command generates validator identity keys centrally. +For this first testnet, that means the coordinator must distribute each private +key securely.

Only the P2P port needs to be + broadly reachable by other validators. + +## Reset Or Re-DKG + +Changing validator identities, validator count, threshold, or DKG output creates +a new network ceremony. Coordinate resets explicitly: + +1. Stop validators. +2. Decide whether the existing chain data is being discarded. +3. Generate or agree on the new `peers.json`. +4. Clear old `share.key`, `output.json`, and partial DKG state from each + validator data directory if the ceremony is being restarted. +5. Run interactive DKG again. +6. Restart validators with the new artifacts. + +Do not mix old and new `peers.json`, `share.key`, or `output.json` files across +validators. + +## Future Improvements + +The current flow can stand up a public-IP testnet, but the rough edges are worth +tracking: + +- Add a `keygen setup` option that accepts an endpoint manifest and writes public + bootstrappers directly, avoiding manual `peers.json` edits. +- Add a flow for operator-generated validator identity public keys so the + coordinator does not create or distribute `validator.key` files. +- Add a per-host systemd or Docker Compose template for validators and + secondaries. +- Document a ZeroTier-based private validator mesh for closed rehearsals. +- Evaluate whether iroh can simplify future P2P connectivity and NAT traversal. +- Make RPC bind address configurable for the validator command, or document the + exact firewall/reverse-proxy pattern used by the public testnet.

"jacobgadikian@gmail.com" Date: Wed, 13 May 2026 18:12:52 +0200 Subject: [PATCH 006/162] feat(ledger): enhance ledger initialization and snapshot restoration - Added support for initializing the ledger with optional genesis allocation application. - Introduced new methods for restoring persisted snapshots in both `LedgerView` and `LedgerService`. - Updated `Cargo.toml` files to include new dependencies for `commonware-consensus` and `commonware-storage`. - Enhanced the runner to recover finalized state from archives, improving state management during node operation. --- Cargo.lock | 2 +

In Simplex BFT consensus this is catastrophic: the bad tx stays in the mempool and gets re-proposed every round, permanently stalling the chain. Replace `?` with `match` + `continue` for both transaction decoding and EVM execution errors. Invalid transactions are now logged with `tracing::warn` and skipped, allowing the remaining valid transactions in the block to execute normally. Co-Authored-By: Claude Opus 4.6 * fix(executor): emit placeholder receipts for skipped txs to preserve index alignment Skipping transactions with `continue` caused receipt indices to diverge from transaction indices. Downstream code (reporters) uses the receipt index as the transaction_index, so after a skipped tx all subsequent receipts would report wrong indices. Add `build_skipped_receipt()` helper that creates a failed receipt with `success: false, gas_used: 0` and emit it before continuing on both decode failures and execution errors. This ensures `receipts.len()` always equals `txs.len()`. Also fix rustfmt formatting and update tests to assert index-preserving behavior.

Capture the Handle returned by each .start() call and spawn a per-task watchdog that awaits the handle. If a critical task ever terminates (panic -> Error::Exited, or unexpected clean exit) the watchdog logs the failure and calls std::process::abort() so that systemd/k8s can restart the node.

This could cause incorrect behavior in clients relying on historical state. Since Kora uses QMDB which only maintains the latest state, this change adds reject_historical_block() validation that returns an explicit Unsupported error for any block parameter other than None, latest, pending, or the current head block number.

Observability stack: - Prometheus with scrape configs for validators and secondary node - Loki + Promtail for centralized log collection via Docker socket - 5 Grafana dashboards: overview, performance, transaction flow, stall diagnostics, and logs - Alert rules for consensus stalls, voter crashes, height drift, nullification rate, memory leaks, and mempool poisoning - Recording rules for pre-computed histogram quantiles and throughput Docker improvements: - Add loadgen binary to the Docker image build - Add observability services to docker-compose (prometheus, loki, promtail, grafana) behind the 'observability' profile Config quality fixes: - Fix recording rule kora:network_bytes_per_block division bug (was using boolean > 0 as divisor instead of actual rate) - Use clamp_min guards instead of > 0 for division-by-zero safety - Fix alerts: use < 0.001 instead of == 0 for float rate comparisons - Fix HeightDrift alert to filter by job="kora-validators" - Add missing 'for' duration to EfficiencyCliff alert - Fix broadcast_get_total label casing in transaction-flow dashboard - Remove unnecessary | logfmt parser from logs dashboard - Add timestamp pipeline stage to Promtail config - Fix Loki max_query_length from 721h to 720h Script improvements: - Add set -o pipefail to devnet-run.sh and devnet-stats.sh - Fix devnet-stats.sh shebang to use /usr/bin/env bash - Make Prometheus URL configurable in devnet-health.sh via PROM_URL - Fix Grafana datasource: set Loki to editable: false Co-Authored-By: Claude Opus 4.6 * fix(observability): address PR review feedback across dashboards and scripts - Fix COMPOSE_PROFILES check to only enable observability when explicitly requested, and include promtail in the service list - URL-encode PromQL queries in devnet-health.sh (curl -G --data-urlencode) - Add python3/date fallbacks for millis() in devnet-stats.sh - Add security warning comment for Docker socket mount in promtail.yml - Fix PromQL boolean inversion bugs: use clamp_min() instead of > 0 filter when dividing (kora-performance.json, 5 occurrences) - Fix brittle float == 0 comparison, use < 0.001 (kora-transaction-flow.json) - Add {job="kora-validators"} filter to exclude secondary node from validator-only metrics (kora-stall-diagnostics.json, kora-overview.json) Co-Authored-By: Claude Opus 4.6 --------- Co-authored-by: will pankiewicz Co-authored-by: Claude Opus 4.6 --- Justfile | 20 + docker/Dockerfile | 3 +- docker/Justfile | 9 +- docker/compose/devnet.yaml | 28 + docker/config/alerts.yml | 249 +++++++ docker/config/loki.yml | 35 + docker/config/prometheus.yml | 18 +- docker/config/promtail.yml | 69 ++ docker/config/recording-rules.yml | 77 +++ docker/grafana/dashboards/kora-logs.json | 277 ++++++++ docker/grafana/dashboards/kora-overview.json | 589 ++++++++++++++--- .../grafana/dashboards/kora-performance.json | 619 ++++++++++++++++++ .../dashboards/kora-stall-diagnostics.json | 506 ++++++++++++++ .../dashboards/kora-transaction-flow.json | 306 +++++++++ .../provisioning/datasources/prometheus.yaml | 9 + docker/scripts/devnet-health.sh | 124 ++++ docker/scripts/devnet-run.sh | 13 +- docker/scripts/devnet-stats.sh | 18 +- 18 files changed, 2881 insertions(+), 88 deletions(-) create mode 100644 docker/config/alerts.yml create mode 100644 docker/config/loki.yml create mode 100644 docker/config/promtail.yml create mode 100644 docker/config/recording-rules.yml create mode 100644 docker/grafana/dashboards/kora-logs.json create mode 100644 docker/grafana/dashboards/kora-performance.json create mode 100644 docker/grafana/dashboards/kora-stall-diagnostics.json create mode 100644 docker/grafana/dashboards/kora-transaction-flow.json create mode 100755 docker/scripts/devnet-health.sh diff --git a/Justfile b/Justfile index 5674983..7052aec 100644 --- a/Justfile +++ b/Justfile @@ -69,6 +69,10 @@ devnet-status: devnet-stats: cd docker && just stats +# Devnet health diagnostics report +devnet-health: + cd docker && just health + # Build docker images docker-build: cd docker && just build @@ -84,3 +88,19 @@ loadtest: # Stress test (10000 txs with 50 accounts) stresstest: cargo run --release -p loadgen --bin loadgen -- --total-txs 10000 --accounts 50 --broadcast-rpc-urls http://127.0.0.1:8546,http://127.0.0.1:8547,http://127.0.0.1:8548 + +# Provision the remote server (one-time) +remote-provision: + cd ansible && ansible-playbook playbooks/provision.yml + +# Deploy to remote server +remote-deploy *args: + cd ansible && ansible-playbook playbooks/deploy.yml {{args}} + +# Reset remote devnet (clean slate) +remote-reset: + cd ansible && ansible-playbook playbooks/reset.yml + +# Start observability on remote +remote-observe: + cd ansible && ansible-playbook playbooks/observe.yml diff --git a/docker/Dockerfile b/docker/Dockerfile index 925f2c7..92aa92f 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -38,7 +38,7 @@ RUN cargo chef cook --release --recipe-path recipe.json COPY . . # Build all binaries -RUN cargo build --release -p kora -p keygen +RUN cargo build --release -p kora -p keygen -p loadgen # ─────────────────────────────────────────────────────────────────────────── # Stage 4: Runtime -

2026 18:47:24 +0200 Subject: [PATCH 060/162] fix(dkg): correct 0-indexed share_index handling in validator startup (#115) * fix(dkg): use 0-indexed share_index directly instead of subtracting 1 The trusted dealer DKG produces 0-indexed share indices (0..n-1), but the validator startup code assumed 1-indexed shares and performed checked_sub(1). This caused the validator receiving share_index=0 to crash on startup, and shifted all other validators' indices by -1, breaking leader election. Replace checked_sub(1) with direct use of share_index plus a bounds check against participant count. Update the DkgOutput doc comment to correctly document 0-indexed shares.

The server exposes OpenMetrics-formatted data from the commonware runtime's built-in metric collectors at /metrics. Changes: - Add axum-based HTTP server spawned via commonware's labeled spawner - Add --metrics-addr CLI flag (default 0.0.0.0:9002) to ValidatorArgs - Wire metrics_addr through ProductionRunner builder pattern - Add axum as a workspace dependency for consistent version management The metrics endpoint is designed to be scraped by Prometheus for monitoring validator health, consensus performance, and resource usage.

By then node0 had advanced several consensus heights, so when a behind-validator was elected leader its `propose()` returned None (missing parent snapshot), nullifying ~26% of views at idle. Two-part fix: 1. Docker startup coordination: - Remove cascading `depends_on` between validators so all 4 start simultaneously via `docker compose up -d`. - Add a shared `startup_barrier` volume where each validator writes a ready-marker file. The entrypoint's `wait_for_barrier()` function blocks until all VALIDATOR_COUNT markers are present, ensuring no validator enters consensus before the others are ready. - `devnet-run.sh` clears stale barrier markers on each fresh start. 2. Better propose() diagnostics in app.rs: - `build_block()`: replace silent `?` on parent_snapshot lookup with an explicit `warn!` log naming the missing parent digest/height. - `propose()`: log a warning when `build_block` returns None so operators can distinguish "node catching up" from other failures.

If the process crashes between partition writes, the database is left in a state where partitions reflect different block heights. This commit adds commit sequence tracking to detect such partial commits on startup. Changes: - Add commit_seq field to QmdbStore, incremented after all three partition writes succeed - Inject sentinel commit sequence markers into each partition batch using well-known keys (COMMIT_SEQ_ACCOUNT_KEY, COMMIT_SEQ_STORAGE_KEY, COMMIT_SEQ_CODE_KEY) that are outside the normal key space - Add read_partition_commit_seqs() to read back markers and compare - Add PartitionCommitSeqs type with is_consistent() check - Add verify_partition_consistency() to CommonwareBackend - Wire the check into QmdbLedger::init_with_genesis() so the node refuses to start if partitions are inconsistent - Add InconsistentPartitions error variants to QmdbError and BackendError - Backward-compatible: databases without markers (pre-fix) pass the check - Recovery is deferred to issue #88 (block replay) Co-Authored-By: Claude Opus 4.6 * fix(storage): address clippy const fn and rustfmt lint failures Add `const` qualifier to `PartitionCommitSeqs::is_consistent()` and `QmdbStore::set_commit_seq()`, collapse struct literals onto single lines in tests, and sort imports alphabetically in ledger.rs. Co-Authored-By: Claude Opus 4.6 * fix(storage): resolve rustfmt formatting failures across QMDB crates Fix byte array line-wrapping (16 bytes per line), collapse single-line expressions, correct import grouping order per rustfmt.toml settings.

On startup, recover_finalized_state() reads this marker and compares it against the archive head to detect whether QMDB may be behind or inconsistent after a crash. The marker uses atomic write (write to temp, then rename) for crash safety. A missing marker is treated as benign (fresh node or first startup after upgrade). A mismatch is logged as a warning so operators can investigate potential state divergence. Closes #88 Co-Authored-By: Claude Opus 4.6 * fix(runner): use sha256::Digest constructor instead of ConsensusDigest type alias ConsensusDigest is a type alias for sha256::Digest, which is a tuple struct. Rust does not allow type aliases to be used as tuple struct constructors. Use the actual struct name sha256::Digest(bytes) instead. Also fix rustfmt formatting in spawn_ledger_observers signature and write_commit_marker if-let binding.

This change adds bookkeeping so a future GC pass can reclaim that dead storage: - Add `selfdestructed_addresses` field to `ExecutionOutcome` - Collect selfdestructed addresses during block execution in the REVM executor - Introduce `SelfdestructGcLog`: an append-only, human-readable log file (`selfdestruct-gc.log`) that records (block_height, address) pairs - Wire the GC log into `FinalizedReporter` so entries are written when finalized blocks contain selfdestructs - Initialize the GC log in the production runner at startup Actual disk reclamation requires upstream Commonware changes; this PR creates the tracking infrastructure so the GC queue is ready. Closes #104 Co-Authored-By: Claude Opus 4.6 * fix(consensus): add missing selfdestructed_addresses field to MockExecutor The ExecutionOutcome struct literal in proposal.rs tests was missing the new selfdestructed_addresses field, which would cause a compilation error. Co-Authored-By: Claude Opus 4.6 * fix(reporters): resolve clippy and fmt CI failures Move `pub use` into alphabetical position with other imports to satisfy rustfmt, suppress too_many_arguments on handle_finalized_update, and collapse nested if into a single condition for collapsible_if lint.

The Commonware resolver interprets this as "peer sent invalid data" and permanently blocks that peer. In a 4-validator cluster all 3 peers get blocked within milliseconds, making catch-up impossible. Introduce a NoOpBlocker that implements the Blocker trait with an empty block() method. Wire it into both the resolver (PeerInitializer) and the simplex engine in place of transport.oracle, which was the previous blocker. The P2P oracle still handles peer discovery and tracking; only the punitive blocking path is disabled. This is a Kora-side workaround. The ideal upstream fix would add retry/back-off semantics to the Commonware resolver so it can distinguish transient verification failures from genuinely Byzantine behaviour.

Transport layer: - Add CHANNEL_TX_GOSSIP (channel 5) alongside the existing consensus and marshal channels - Register the channel in all transport builders (production, simulated, network provider, bundle) - Add TxGossipChannel / SimTxGossipChannel wrapper types Runner wiring: - Spawn an outbound gossip task that reads from an internal mpsc channel and broadcasts raw transaction bytes to all peers via Recipients::All - Spawn an inbound gossip task that receives gossipped transactions, validates them against on-chain state, and inserts valid ones into the local mempool via LedgerService::submit_tx - Modify TxSubmitCallback to forward accepted RPC transactions to the outbound gossip channel - Add a bounded seen-set (HashSet, capacity 65536) shared between inbound, outbound, and RPC paths to prevent re-broadcasting and duplicate processing Co-Authored-By: Claude Opus 4.6 * fix(runner): use IoBuf::as_ref() for gossip inbound deserialization The P2P receiver returns commonware_runtime::IoBuf which does not auto-coerce to &[u8] for alloy_primitives::Bytes::copy_from_slice. Call .as_ref() explicitly to get the byte slice. Also fix rustfmt formatting of the trace! macro call. Co-Authored-By: Claude Opus 4.6 * feat(gossip): make transaction gossip opt-in via configuration Transaction gossip is now gated behind a `network.tx_gossip` config field (default false) and a `--tx-gossip` CLI flag. The P2P gossip channel is still registered in the transport layer for uniformity, but the inbound/outbound tasks are only spawned when enabled. The RPC callback conditionally forwards accepted transactions to gossip. The devnet compose defaults TX_GOSSIP to true so existing devnets keep gossip active, while production deployments remain opt-in. Co-Authored-By: Claude Opus 4.6 * style(runner): fix rustfmt line length in gossip info log Break the long info!() macro call across multiple lines to satisfy the rustfmt `use_small_heuristics = "Max"` setting. Co-Authored-By: Claude Opus 4.6 * fix(runner): remove explicit `ref` in implicitly-borrowing pattern In Rust 2024 edition, explicit `ref` binding modifiers are not allowed when the matched expression is already a reference. Remove the redundant `ref` keywords from the gossip/seen destructuring pattern.

From ace5feb92e43dffc619c1b4cd6a49d951259805b Mon Sep 17 00:00:00 2001 From: Will <9498646+wpank@users.noreply.github.com> Date: Sat, 23 May 2026 16:07:35 +0200 Subject: [PATCH 077/162] fix(runner): state sync and crash recovery for restarted validators (#149) (#192) Restarted validator nodes could not catch up to the running network due to multiple interacting failures: 1. After restart, only the HEAD snapshot existed in the cache. The consensus engine's ancestry walk would fail to find parent snapshots for any block not directly succeeding HEAD. 2. verify_block() returned false for valid blocks when the parent snapshot was missing, even during legitimate catch-up. The resolver interpreted false as "malicious peer" and permanently blocked them. 3. All peers were blocked within ~50ms, making the node permanently degraded. This commit fixes the problem with a layered approach: - Pre-populate the snapshot cache on startup by restoring the last 16 finalized blocks from the archive. This gives the ancestry walk multiple stop-points, reducing the number of blocks that need re-verification after restart. - Add catch-up trust to verify_block: when the parent snapshot is missing and the node's recovered height is significantly behind the block being verified, trust the finality certificate instead of returning false. The block has already been finalized by consensus (2/3+ validators verified it), so trusting it during catch-up is safe. - Track recovered_height in RevmApplication and advance it as blocks are successfully verified or trusted, so the node eventually exits catch-up mode.

A consensus-agreed block that failed to finalize would be permanently lost from the node's QMDB state, causing silent state divergence. Changes: - Add FinalizationError enum with 7 variants covering all failure modes - Classify errors as retryable (execution, root computation, missing snapshot, persist failures) or non-retryable (state root mismatch, evicted parent snapshot) - Add finalize_with_retry() wrapper with 3 attempts and exponential backoff (100ms, 200ms, 400ms) - Distinguish transiently missing parent snapshots (catch-up race) from permanently evicted ones via new LedgerService::is_snapshot_persisted() - Log attempt number, error kind, and full diagnostic context on failure - Log CRITICAL-level messages when all retries are exhausted Co-Authored-By: Claude Opus 4.6 * fix(reporters): resolve clippy and rustfmt CI failures Add `const` to `is_retryable` and `metric_label` methods to satisfy the `missing_const_for_fn` lint, and reformat the `BlockExecution::execute` call chain to match rustfmt style_edition=2024 expectations. Co-Authored-By: Claude Opus 4.6 * fix(reporters): add missing gc_log args in finalize_success_tests Two test call sites in finalize_success_tests passed 7 arguments to handle_finalized_update which expects 8. The gc_log parameter (added in #137) was missing from successful_finalization_persists_and_acknowledges and finalization_updates_block_index.

Restructure the per-account send loop from `for _ in 0..count` to `while sent < count` to correctly handle nonce resyncs without consuming a send slot. Remove the post-loop nonce rewind (`account.set_nonce(nonce)`) that would overwrite resynced values. Classify RPC errors into four categories -- nonce too low (implicit success), already in pool (implicit success), nonce gap (resync and retry), and transient (exponential backoff) -- instead of retrying all errors identically. Add periodic progress reporting every 5 seconds with success/failed/TPS counters, post-run inclusion verification comparing expected vs on-chain nonces, transport-only fallback in send_raw_transaction_to (semantic rejections no longer fall back to other validators), resilient nonce initialization with fallback across all RPC endpoints, and an optional --timeout-secs flag for overall load test duration limits. Closes #143 Co-Authored-By: Claude Opus 4.6 * fix(loadgen): rustfmt formatting for use_small_heuristics=Max Collapse chain call and info! macro to single lines to match rustfmt Max heuristic expectations. Co-Authored-By: Claude Opus 4.6 * fix(loadgen): correct verification metrics and log nonce resync failures The post-run verification was summing absolute on-chain nonces into total_confirmed, producing misleading metrics when accounts had pre-existing nonces. Track each account's starting nonce and compute per-run confirmed counts (chain_nonce - starting_nonce). Also add warn! logging and backoff when get_nonce_from_any fails during nonce gap and nonce-too-low recovery, replacing silent error swallowing with actionable diagnostics.

In both cases, the incomplete excluded set could cause transactions already included in recent unpersisted blocks to be re-included in a new proposal. Now both code paths explicitly detect the gap and refuse to build: - `app.rs`: returns `Option` instead of `BTreeSet`, with `None` signaling the caller to nullify the round - `proposal.rs`: logs a warning before returning the error It is safer to produce an empty block than to risk duplicate transaction execution.

This caused containers to hang for 30s until SIGKILL. - Register a SIGTERM handler alongside SIGINT in both the validator runner and the secondary peer CLI entry point - Use `tokio::select!` to resolve on whichever signal arrives first - Lower Docker stop_grace_period from 30s to 5s (shutdown is now fast) - Add `init: true` to validator containers so signals are forwarded correctly to PID 1 - Remove unused `futures` dependency from kora binary crate Co-Authored-By: Claude Opus 4.6 * style: fix rustfmt line-length wrapping for SIGTERM signal handler Reformat the `tokio::signal::unix::signal(...)` chain in both cli.rs and runner.rs to satisfy the style_edition=2024 max-width rules.

Before giving up on a missing parent snapshot, briefly poll (up to 5 x 10 ms = 50 ms) for it to become available. In the common case the snapshot arrives within the first few milliseconds, converting what would have been a nullified view into a successful proposal. Closes #156 Co-Authored-By: Claude Opus 4.6 * fix(runner): measure wait_ms from poll start, not function start The `wait_ms` diagnostic in `build_block` was using `start.elapsed()` which captured total time from the beginning of the function, including the initial (non-polling) parent snapshot lookup. This made the logged wait time appear longer than the actual polling duration. Introduce a `poll_start` instant captured immediately before the polling loop so that `wait_ms` accurately reflects only the time spent polling for the parent snapshot to become available.

Metrics added: - kora_txpool_size: current pool size gauge - kora_txpool_pending: pending (executable) tx count gauge - kora_txpool_queued: queued (future-nonce) tx count gauge - kora_txpool_rejected_total: rejected tx counter by reason label - kora_block_build_time_seconds: block build duration histogram - kora_block_txs_included: txs in last built block gauge - kora_blocks_finalized_total: successful finalizations counter - kora_finalization_failures_total: failed finalizations counter Co-Authored-By: Claude Opus 4.6 * fix(metrics): rustfmt line wrapping and clippy useless_conversion Fix CI failures: - Wrap long import and registry.register() calls to satisfy rustfmt - Remove .into_iter() on BLOCK_BUILD_BUCKETS since Histogram::new already accepts IntoIterator Co-Authored-By: Claude Opus 4.6 --------- Co-authored-by: will pankiewicz Co-authored-by: Claude Opus 4.6 Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: faddat <7142025+faddat@users.noreply.github.com> --- Cargo.toml | 1 + crates/node/metrics/Cargo.toml | 14 ++++ crates/node/metrics/src/lib.rs | 139 +++++++++++++++++++++++++++++++ crates/node/reporters/Cargo.toml | 1 + crates/node/reporters/src/lib.rs | 26 ++++++ crates/node/runner/Cargo.toml | 2 + crates/node/runner/src/app.rs | 17 ++++ crates/node/runner/src/runner.rs | 25 +++++- crates/node/txpool/Cargo.toml | 1 + crates/node/txpool/src/pool.rs | 90 +++++++++++++++++++- 10 files changed, 312 insertions(+), 4 deletions(-) create mode 100644 crates/node/metrics/Cargo.toml create mode 100644 crates/node/metrics/src/lib.rs diff --git a/Cargo.toml b/Cargo.toml index eabc4d6..368d47c 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -48,6 +48,7 @@ codegen-units = 1 # Local crates kora-builder = { path = "crates/node/builder" } kora-domain = { path = "crates/node/domain" } +kora-metrics = { path = "crates/node/metrics" } kora-cli = { path = "crates/utilities/cli" } kora-crypto = { path = "crates/utilities/crypto" } kora-backend = { path = "crates/storage/backend" } diff --git a/crates/node/metrics/Cargo.toml b/crates/node/metrics/Cargo.toml new file mode 100644 index 0000000..6b8e150 --- /dev/null +++ b/crates/node/metrics/Cargo.toml @@ -0,0 +1,14 @@ +[package] +name = "kora-metrics" +version.workspace = true +edition.workspace = true +rust-version.workspace = true +license.workspace = true +repository.workspace = true +description = "Application-level Prometheus metrics for Kora nodes" + +[lints] +workspace = true + +[dependencies] +prometheus-client.workspace = true diff --git a/crates/node/metrics/src/lib.rs b/crates/node/metrics/src/lib.rs new file mode 100644 index 0000000..2053887 --- /dev/null +++ b/crates/node/metrics/src/lib.rs @@ -0,0 +1,139 @@ +//!

Increase persisted retention from 64 to 256 to reduce eviction pressure. Add retry with exponential backoff for parent snapshot lookup during finalization to handle transient unavailability.

Add a proposal lag guard that skips proposals when the tip is more than 8 blocks ahead of the finalized height, preventing fast leaders from building unbounded chains of unfinalized snapshots. Co-Authored-By: Claude Opus 4.6 * fix(reporters): add missing node_state and gc_log args in test calls The handle_finalized_update function gained a node_state parameter in this PR, but the three test call sites were not updated. Two of them were also already missing the gc_log argument from a prior commit. This fixes all three to pass the correct number of arguments. Co-Authored-By: Claude Opus 4.6 * fix(alerts): update build duration thresholds for 1s leader timeout The leader timeout was reduced from 5s to 1s in this PR, but the alert thresholds and descriptions in alerts.yml still referenced 2s. Update SlowBlockBuild (p95 > 0.5s) and CriticalBlockBuild (p99 > 0.8s) to match the new 1s default.

If the bootstrap node is down when another node restarts (OOM, upgrade, crash), the restarting node enters a loop of 120s wait -> exit -> Docker restart -> 120s wait, unable to rejoin the network until the bootstrap peer comes back. The bootstrap wait only serves a purpose on first startup for initial peer discovery. On subsequent starts the node already has its DKG keys and peer configuration; the Commonware P2P layer handles reconnection internally. Changes: - Validator mode: skip barrier and bootstrap wait when last_committed_digest exists on the persistent /data volume (indicates the node has finalized at least one block before) - Secondary mode: write a .bootstrap_done marker after first successful bootstrap wait; skip the wait on restarts when the marker exists - Move .ready marker creation after all blocking startup checks in both validator and secondary modes so it accurately signals readiness - DKG mode is not affected (already has early exit on share.key) Co-Authored-By: Claude Opus 4.6 * fix(docker): merge main changes to resolve conflicts Agent-Logs-Url: https://github.com/Nunchi-trade/daeji/sessions/3eace897-2702-4c8b-ad7f-44db8b4e6c73 Co-authored-by: faddat <7142025+faddat@users.noreply.github.com> --------- Co-authored-by: will pankiewicz Co-authored-by: Claude Opus 4.6 Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: faddat <7142025+faddat@users.noreply.github.com> --- docker/scripts/entrypoint.sh | 80 ++++++++++++++++++++++++------------ 1 file changed, 54 insertions(+), 26 deletions(-) diff --git a/docker/scripts/entrypoint.sh b/docker/scripts/entrypoint.sh index 8bbfbbf..0145a73 100644 --- a/docker/scripts/entrypoint.sh +++ b/docker/scripts/entrypoint.sh @@ -116,26 +116,46 @@ case "$MODE" in log "DKG key fingerprints: share.key=${SHARE_KEY_HASH} output.json=${OUTPUT_HASH}" cp "${SHARED_DIR}/genesis.json" "${DATA_DIR}/" 2>/dev/null || true - touch "${DATA_DIR}/.ready" - # Wait for all validators to be ready before starting consensus. - # This prevents height drift caused by staggered startup: if the - # bootstrap node enters consensus minutes before the others, it - # advances heights alone and later leaders return None from - # propose() because they lack the parent snapshot. - wait_for_barrier "$VALIDATOR_COUNT" + # Detect whether this is a first startup or a restart by checking + # for the commit marker on the persistent /data volume.

Reduces average snapshot-wait latency from ~5-10ms to sub-millisecond. - Increase `MAX_PROPOSAL_LAG` from 8 to 32: the previous value was too tight after node restart, causing a livelock where the finalization pipeline could never catch up because all proposals were being skipped.

This kept ~27 seconds of cached consensus artifacts in memory at 93 blocks/s -- roughly 10x more than needed. Reduce both defaults to 256 to start pruning within ~2.7 seconds of startup and free memory in smaller chunks. The CheckpointedArchive's Certificates::prune() and Blocks::prune() implementations silently discarded the height parameter (no-op). Replace with tracing::warn! so skipped pruning is visible in logs and can be tracked via monitoring. The underlying immutable::Archive has no deletion API by design; switching to prunable::Archive is a follow-up. Co-Authored-By: Claude Opus 4.6 * fix(marshal): add tracing to dependencies for archive prune logging The tracing::warn! calls in the Certificates and Blocks prune() stubs require tracing as a regular dependency, not just a dev-dependency. Moves tracing from [dev-dependencies] to [dependencies] to fix E0433 "cannot find module or crate `tracing`" build errors. Co-Authored-By: Claude Opus 4.6 * fix(marshal): downgrade archive prune log from warn to debug The immutable archive's prune no-op fires on every marshal prune cycle (every few seconds). This is expected behavior, not an actionable warning. Use debug! to reduce log noise.

Rayon's work-stealing scheduler busy-waits via sched_yield when idle, and with BLS batches arriving only ~30 times/sec (~10ms each), the second thread spends >90% of its time in idle spin loops. On our 15-node devnet (0.75-1.2 CPU per container), this wastes ~0.21 cores per node and generates 100K+ involuntary context switches every 5 minutes. Additionally, set TOKIO_WORKER_THREADS=2 in the Docker entrypoint. Inside containers, Tokio defaults to the *host* CPU count (e.g. 12 on our Hetzner server) rather than the cgroup limit, spawning ~17 idle worker threads that compete for the CFS quota. This contributes to health-check timeouts and scheduling jitter under CPU pressure.

Co-Authored-By: Claude Opus 4.6 * fix(transport): increase resolver backlog to 2048 for catch-up reliability The removal of .with_backlog(2048) silently halved the resolver backlog from 2048 to 1024.

Pass ChangeSet by reference to compute_root_from_store (was by value). Eliminates one deep BTreeMap clone per block in verify_block, build_block, finalize_block, and replay — 4 clone eliminations total. 2. Pre-allocate Vec in StateRoot::transition. The buffer was starting at 0 capacity and growing through multiple reallocations. Now estimates ~128 bytes per account to minimize reallocs. 3. Batch 3 sequential block_on calls in StateDbAdapter::basic_ref into a single async block. Each block_on invocation has overhead from block_in_place + handle.block_on; batching reduces this 3x per account lookup during EVM execution.

This caused stale data to be returned between checkpoints. Introduce `LiveState`, a `StateDbRead` adapter that delegates every read through `LedgerService::latest_state()` to query the latest in-memory overlay. Wire it into `IndexedStateProvider` in the runner instead of the raw `QmdbState` handle. Also fix two block format deviations from the Ethereum JSON-RPC spec: - Add missing `sha3Uncles` field set to the keccak256 of an empty RLP list (required by EIP-1474, expected by ethers.js/viem) - Set `logsBloom` to 256 zero bytes instead of empty bytes (clients expect a fixed 256-byte bloom filter) Co-Authored-By: Claude Opus 4.6 * fix(rpc): fix import ordering and restrict EMPTY_UNCLE_HASH visibility Move `pub use live_state::LiveState` to the correct position within the import block to satisfy rustfmt's `group_imports = "StdExternalCrate"` ordering. Change `EMPTY_UNCLE_HASH` from `pub` to `pub(crate)` since it is only used within the kora-rpc crate, fixing a clippy unreachable_pub warning. Co-Authored-By: Claude Opus 4.6 * fix(ledger): make LiveState::new a const fn Clippy's `missing_const_for_fn` lint requires functions that can be evaluated at compile time to be marked `const`. `LiveState::new` simply assigns a struct field and qualifies. Co-Authored-By: Claude Opus 4.6 * fix(rpc): populate mix_hash with actual prevrandao instead of zero The mix_hash field in RPC block responses was hardcoded to B256::ZERO. Post-merge Ethereum repurposes this field to carry the prevrandao value, which the EVM PREVRANDAO opcode reads. Since the chain already computes a real prevrandao from VRF seeds during consensus, thread that value through IndexedBlock so the RPC response matches what the EVM executed with.

Fixes: - acknowledge_checkpoint: defer marshal acks between checkpoints and batch-drain at boundaries so the marshal knows exactly which blocks are durably persisted (Fix A) - is_durable_partition -> is_ephemeral_partition: invert the partition classification so unknown partitions default to durable/disk-backed rather than ephemeral/in-memory (Fix B) - application_metadata_height: validate buffer length (28 bytes) and version field (reject > 1024) to prevent treating corrupted metadata as a valid block height for sync decisions (Fix C) - CheckpointedArchive::should_sync: use floor-division boundary detection instead of exact modulo, so out-of-order block insertion past a boundary still triggers sync (Fix D) - restore_checkpoint_and_replay_tail: fail hard with anyhow::bail when a commit marker exists but does not match any archived block, instead of silently proceeding with potentially inconsistent state (Fix E) - CheckpointedArchive::new: clamp checkpoint_interval=0 to 1, matching the guards in NoSyncStorage and FinalizedReporter (Fix F) Also fixes broken test callsites (missing node_state arg, extra None) and adds three new unit tests for the archive boundary logic. Co-Authored-By: Claude Opus 4.6 * fix(clippy): use is_multiple_of and if-let for cleaner idioms Replace manual `% x == 0` with `is_multiple_of()` (clippy::manual_is_multiple_of) and `is_some()` + `expect()` with `if let Some()` to satisfy clippy lints. Co-Authored-By: Claude Opus 4.6 * fix(clippy): remove unused validate_commit_marker function The function's logic was inlined into restore_checkpoint_and_replay_tail with stricter safety guarantees (bail on mismatch instead of warning). The leftover definition triggers -D dead-code. Co-Authored-By: Claude Opus 4.6 * fix(storage): tighten ephemeral partition patterns to avoid false positives Use "-finalization-" and "-notarization-" (with trailing dash) instead of "-finalization" and "-notarization" to prevent matching the durable finalization archive partition names (e.g. "kora-finalizations-by-height-key").

With 15 validators, operators setting --threshold=10 would expect 10 active nodes to suffice, but N3f1 requires 11 -- causing silent liveness failure. Changes: - Remove --threshold from keygen setup and dkg-deal CLI args - Remove threshold field from DkgConfig struct; DkgConfig::t() now computes quorum via N3f1::quorum(n) instead of returning a stored value - DkgOutput::load() recomputes threshold from N3f1 on load, ignoring any stale value persisted in output.json (backward compatible) - peers.json now writes "quorum" instead of "threshold"; load_peers() no longer requires a threshold/quorum key (both formats accepted) - Add quorum logging at validator startup and DKG ceremony start - Remove --threshold from devnet.yaml compose commands Co-authored-by: will pankiewicz Co-authored-by: Claude Opus 4.6 --- bin/keygen/src/dkg_deal.rs | 17 ++-- bin/keygen/src/setup.rs | 31 +++--- bin/kora/src/cli.rs | 35 +++++-- crates/node/dkg/src/ceremony.rs | 4 +- crates/node/dkg/src/config.rs | 162 +++----------------------------- crates/node/dkg/src/output.rs | 18 +++- crates/node/dkg/src/tests.rs | 4 - docker/compose/devnet.yaml | 3 - 8 files changed, 91 insertions(+), 183 deletions(-) diff --git a/bin/keygen/src/dkg_deal.rs b/bin/keygen/src/dkg_deal.rs index e98df5a..1ea12aa 100644 --- a/bin/keygen/src/dkg_deal.rs +++ b/bin/keygen/src/dkg_deal.rs @@ -11,7 +11,7 @@ use commonware_cryptography::bls12381::{ dkg, primitives::{sharing::Mode, variant::MinSig}, };

Catch-up window collapsed after a single block: `is_catching_up()` checked `block_height > recovered_height + CATCH_UP_THRESHOLD` (2), but each trusted block advanced `recovered_height` via `fetch_max()`. After trusting one block at height N+3, `recovered_height` became N+3, so block N+4 was only 1 ahead -- below the threshold. The window shut after a single block. Fix: Split into two atomics -- `recovered_height` (immutable, set once at startup) and `last_verified_height` (advanced only by full-execution verification, never by certificate trust). The catch-up window stays open until full execution catches up to `recovered_height + 64`. 2. MAX_PROPOSAL_LAG=8 blocked proposals after restart: The finalization pipeline drains slowly during catch-up, so the gap between tip and finalized height quickly exceeds 8. Every proposal was skipped, preventing the node from producing blocks and slowing recovery. Fix: Increase MAX_PROPOSAL_LAG from 8 to 32. 3. FinalizedReporter permanently failed on evicted parent snapshots: When a parent snapshot was persisted then evicted from memory, `finalize_block` returned `ParentSnapshotEvicted` which was non-retryable. This stalled the entire finalization pipeline. Fix: Instead of returning an error, restore the block as a trusted persisted snapshot (the block is consensus-finalized, so its state root is authoritative). RPC indexing data is lost for these blocks, but the alternative was permanent pipeline death. Additional improvements: - Increase SNAPSHOT_PREPOPULATE_COUNT from 16 to 64 - Increase CATCH_UP_THRESHOLD from 2 to 64 - Downgrade catch-up trust log from warn to debug (expected during recovery) - Add info log when first full-execution verification passes recovery point - Better diagnostic fields in all recovery-related log messages Co-Authored-By: Claude Opus 4.6 * fix(recovery): advance last_verified_height and handle empty changesets during catch-up Fix two bugs in the node restart catch-up mechanism: 1. last_verified_height never advances: Certificate-trusted blocks are stored in the snapshot store but do not update last_verified_height. When a subsequent verify() call encounters these blocks, the ancestry walk stops (query_state_root returns Some), so the full-execution path is never reached, and last_verified_height stays stuck at the recovered_height. Fix: advance last_verified_height in the "already verified" early-return path of verify_block. 2. restore_persisted_snapshot loses state: Certificate-trusted snapshots are created with empty changesets over the current QMDB state. When a child block tries full execution against this parent, the state is wrong (missing intermediate changes), causing state root mismatch and permanent verification failure. Fix: during catch-up, fall back to certificate-trust when execution fails, compute_root fails, or state root mismatches, instead of rejecting the block. Also increase MAX_PROPOSAL_LAG from 32 to 64 (matching the value chosen in PR #224) to give finalization sufficient headroom during recovery.

This kept ~27 seconds of cached consensus artifacts in memory at 93 blocks/s -- roughly 10x more than needed. Reduce both defaults to 256 to start pruning within ~2.7 seconds of startup and free memory in smaller chunks. The CheckpointedArchive's Certificates::prune() and Blocks::prune() implementations silently discarded the height parameter (no-op). Replace with tracing::warn! so skipped pruning is visible in logs and can be tracked via monitoring. The underlying immutable::Archive has no deletion API by design; switching to prunable::Archive is a follow-up. Co-Authored-By: Claude Opus 4.6 * fix(txpool): enforce base fee floor in gas price validation Loadgen hardcoded max_fee_per_gas=0 and max_priority_fee_per_gas=0 in EIP-1559 transactions, but the chain's INITIAL_BASE_FEE is 1 gwei. The mempool's min_gas_price defaulted to 0, silently accepting transactions that would fail execution-time base fee validation. - Set loadgen gas prices to 10 gwei max fee / 1 gwei priority fee - Change PoolConfig min_gas_price default from 0 to 1 gwei (matching INITIAL_BASE_FEE) so the mempool rejects underpriced txs at intake Co-Authored-By: Claude Opus 4.6 * fix(ci): rustfmt comment alignment and marshal tracing dependency The CI format check requires trailing comments within a struct literal to be column-aligned. Add padding spaces to the max_tx_size comment so it aligns with the min_gas_price comment on the next line. The tracing::warn! calls in CheckpointedArchive's Certificates::prune() and Blocks::prune() implementations are in non-test code, so tracing must be a regular dependency rather than a dev-dependency.

Root cause: Docker Compose replaces (not merges) the environment list when a child service defines its own `environment:` key, so the TX_GOSSIP variable from the anchor was silently dropped for all four validator services. Fix: add TX_GOSSIP=${TX_GOSSIP:-true} to each validator's environment block so the variable actually reaches the entrypoint script. Also adds: - Prometheus metrics for gossip activity (broadcast, received, failed, invalid) so silent failures are immediately visible on /metrics - Explicit DISABLED log in entrypoint.sh when gossip is off, making misconfiguration obvious in container logs Co-Authored-By: Claude Opus 4.6 * fix(metrics): remove _total suffix from gossip counter names prometheus_client auto-appends _total for Counter types per OpenMetrics spec. Registering with _total suffix causes double-suffixed names like kora_gossip_tx_broadcast_total_total on the Prometheus endpoint. Co-Authored-By: Claude Opus 4.6 * fix(gossip): refresh state on each inbound transaction validation The gossip inbound handler captured qmdb_state() once at startup and reused it for all subsequent validations. As blocks finalized and nonces advanced, this stale snapshot caused valid transactions to be rejected (nonce appears "in the future" relative to old state). Now uses ledger.latest_state() on each validation, matching how the RPC tx_submit path already works. This was a root cause of gossip being reported as "completely non-functional" in devnet testing.

At 30 blocks/s this fills a 444 GB SSD in ~53 hours. Switch the archive backend from commonware's immutable::Archive to prunable::Archive, which supports removing old entries via a section- based pruning mechanism. Add a Prunable trait so CheckpointedArchive can forward prune calls from the marshal's Blocks/Certificates stores to the underlying prunable archive. Key changes: - Add Prunable trait + impl for prunable::Archive in archive.rs - Wire CheckpointedArchive's Blocks::prune / Certificates::prune to delegate to the inner archive instead of returning Ok(()) as a no-op - Add init_prunable / init_prunable_checkpointed to ArchiveInitializer using EightCap translator (8-byte key prefix for hash indexing) - Update runner, e2e harness, and integration tests to use prunable archives Co-Authored-By: Claude Opus 4.6 * fix(marshal): resolve clippy and fmt lint errors Fix use_self lint by replacing PrunableArchive::prune with Self::prune, fix default_constructed_unit_structs lint by using EightCap directly instead of EightCap::default(), and consolidate commonware_storage imports for rustfmt compliance. Co-Authored-By: Claude Opus 4.6 * fix(marshal): detect and remove legacy immutable archive partitions on upgrade When upgrading from immutable::Archive to prunable::Archive, the old backend's partitions (-metadata, -freezer-table, -freezer-key, -freezer-value, -ordinal) remain on disk while the new backend creates fresh partitions (-key, -value). This silently orphans all archive history and wastes disk space. Add ArchiveInitializer::migrate_from_immutable() which scans for legacy partition names, logs a warning, and removes them before the prunable backend is initialized. Called from the production runner for both the finalizations and blocks archives. Co-Authored-By: Claude Opus 4.6 * fix(marshal): move tracing from dev-dependencies to dependencies The migrate_from_immutable() method uses tracing::warn in production code, not just tests. Moving it to [dependencies] fixes the build.

Switch from allowlist (`is_ephemeral_partition`) to denylist (`is_durable_partition`): only `-application-metadata` partitions hit disk. Everything else — marshal freezer data, consensus caches, journals — stays in memory. The marshal's freezer data (block storage, ordinals, keys, values) was being written to disk on every block because the old allowlist didn't match marshal partition names, causing a 12x throughput regression (95→8 blocks/s). Also cap Tokio workers (8) and Rayon threads (2) inside Docker containers to prevent thread oversubscription — Docker exposes host CPU count (12) not cgroup limit (2), creating 24+ threads on 2 CPUs.

Changes: - Double snapshot poll budget from 50ms to 100ms (10 attempts x 10ms) so leaders wait long enough for the parent snapshot under contention - Raise MAX_PROPOSAL_LAG from 8 to 16 to prevent finalization stalls from cascading into proposal skips across all leaders - Reduce certification timeout from 10s to 5s to halve the stall per dead-leader rotation - Reduce nullification retry timeout from 2s to 1s for faster recovery from transient snapshot misses - Add three new Prometheus metrics (kora_proposal_snapshot_misses_total, kora_proposal_lag_skips_total, kora_snapshot_poll_wait_seconds) to distinguish nullification root causes in production Co-authored-by: will pankiewicz Co-authored-by: Claude Opus 4.6 --- crates/node/config/src/consensus.rs | 16 ++++++++++-- crates/node/metrics/src/lib.rs | 40 +++++++++++++++++++++++++++++ crates/node/runner/src/app.rs | 39 +++++++++++++++++++++------- 3 files changed, 84 insertions(+), 11 deletions(-) diff --git a/crates/node/config/src/consensus.rs b/crates/node/config/src/consensus.rs index b61c436..51a5fe2 100644 --- a/crates/node/config/src/consensus.rs +++ b/crates/node/config/src/consensus.rs @@ -35,10 +35,22 @@ pub const DEFAULT_SIMPLEX_WRITE_BUFFER_BYTES: usize = 16 * 1024 * 1024; pub const DEFAULT_SIMPLEX_LEADER_TIMEOUT_SECS: u64 = 1; /// Default Simplex certification timeout in seconds. -pub const DEFAULT_SIMPLEX_CERTIFICATION_TIMEOUT_SECS: u64 = 10; +/// +/// This bounds how long validators wait for enough votes to form a +/// finality certificate after notarizing a block.

Cache block hash with OnceLock: Block.id() (keccak256 of the encoded block) is now computed once and cached via OnceLock. Previously each call to id(), digest(), or commitment() would re-serialize and re-hash the entire block. On the consensus hot path a single block's hash is computed 3-6 times per round (propose, verify, finalize, index). The cache is propagated through Clone and excluded from PartialEq/Debug/codec. 2. Eliminate EvmState clone in extract_changes: Changed extract_changes() to take &EvmState instead of owned EvmState. The caller previously cloned the entire HashMap (accounts, storage BTreeMaps, bytecode) just so it could pass one copy to extract_changes and the other to db.commit(). Now we iterate by reference, copying only the individual field values we need, then move the original into commit(). 3. Empty block short-circuit: When txs is empty, skip EVM context construction, StateDb adapter cloning, State builder, and Journal allocation entirely. Empty blocks are the common case on low-load networks and consensus idle rounds. Pre/post execution hooks still run to maintain correct state transitions. All Block struct-literal construction sites are migrated to the new Block::new() constructor to support the private cached_id field. Co-Authored-By: Claude Opus 4.6 * fix: resolve CI format and clippy failures Make Block::new() const fn to satisfy missing_const_for_fn lint, and collapse multi-line function calls to single lines per rustfmt Max heuristics. Co-Authored-By: Claude Opus 4.6 * fix(block): correct doc comment for Block::new() cache behavior The OnceLock cache is lazily populated on first call to id(), not eagerly initialized in the constructor.

But the rest of the system runs a single static epoch: consensus uses Epoch::zero() (simplex config), EPOCH_LENGTH = u64::MAX in the runner, and the certificate provider's scoped() ignores the epoch. On a resolver backfill, marshal handle_deliver checks finalization.epoch() == epocher.containing(height).epoch(). With the 20-block epocher this was e.g. 0 != 164 at height ~3286, so every backfilled finalization was rejected ("invalid data received"). The finalization pipeline then never advanced and the proposal lag guard blocked all proposals, so a restarted validator could never catch up. Live consensus blocks don't go through this epoch check, which is why the network ran fine until a node restarted. Set DEFAULT_BLOCKS_PER_EPOCH to u64::MAX so the marshal uses a single epoch, matching consensus. Verified on a 4-validator devnet: before, a restarted validator stayed stuck and the marshal logged FINALIZED_CHECK with ep_fin=Epoch(0) vs ep_bounds=Epoch(164); after, a restarted validator catches up to the tip in ~8s and stays synced (gap 0) with zero epoch rejections. Follow-up: ideally thread the runner's EPOCH_LENGTH into the marshal init so the two epoch lengths can't diverge. --- crates/network/marshal/src/actor.rs | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/crates/network/marshal/src/actor.rs b/crates/network/marshal/src/actor.rs index fcd1511..4f480d5 100644 --- a/crates/network/marshal/src/actor.rs +++ b/crates/network/marshal/src/actor.rs @@ -72,7 +72,7 @@ impl ActorInitializer { pub const DEFAULT_VALUE_WRITE_BUFFER: NonZeroUsize = NZUsize!(1024 * 1024); /// The default blocks per epoch. - pub const DEFAULT_BLOCKS_PER_EPOCH: NonZeroU64 = NZU64!(20); + pub const DEFAULT_BLOCKS_PER_EPOCH: NonZeroU64 = NZU64!(u64::MAX); /// The default partition prefix. pub const DEFAULT_PARTITION_PREFIX: &'static str = "marshal"; @@ -238,7 +238,7 @@ mod tests { assert_eq!(ActorInitializer::DEFAULT_REPLAY_BUFFER.get(), 8 * 1024 * 1024); assert_eq!(ActorInitializer::DEFAULT_KEY_WRITE_BUFFER.get(), 1024 * 1024); assert_eq!(ActorInitializer::DEFAULT_VALUE_WRITE_BUFFER.get(), 1024 * 1024); - assert_eq!(ActorInitializer::DEFAULT_BLOCKS_PER_EPOCH.get(), 20); + assert_eq!(ActorInitializer::DEFAULT_BLOCKS_PER_EPOCH.get(), u64::MAX); assert_eq!(ActorInitializer::DEFAULT_PARTITION_PREFIX, "marshal"); } } From b481fdb1dc4ea289d36f71aee1b88296b7c2b8f7 Mon Sep 17 00:00:00 2001 From: Eren Yegit <115787683+erenyegit@users.noreply.github.com> Date: Mon, 25 May 2026 21:52:26 +0300 Subject: [PATCH 123/162] fix(devnet): mount startup_barrier into init-setup so just devnet config succeeds (#246) The interactive-DKG init container (init-setup) chowns /barrier in its setup command, but unlike init-config it didn't mount the startup_barrier volume at /barrier.

The ready health check writes its stall-detection state to /tmp/healthcheck_block. The write failed with Permission denied and, with set -e, the script exited 1, so every validator was reported unhealthy even though consensus and RPC were fully working. That made just devnet / just trusted-devnet time out at the [2/3] waiting-for-validators step. Fix: set the /tmp tmpfs mode from 0700 to 1777 (standard sticky, world-writable /tmp) on all services. The validator path is the one observed failing and validated; the observability services carried the identical mode and are fixed for consistency.

Per-connection limiter (primary): each jsonrpsee ConnectionId gets its own TokenBucket so one aggressive client cannot exhaust the budget for all others. Stale entries are pruned every 60s after 5min of inactivity to bound memory. 2. Global limiter (backstop): the original shared bucket is retained as an aggregate throughput ceiling to protect the node from total overload. Additionally, cap JSON-RPC batch requests to 50 calls via BatchRequestConfig::Limit to prevent a single HTTP POST from draining the entire per-connection budget in one shot. Note: jsonrpsee 0.24 only exposes ConnectionId (not peer IP) in request extensions, so the per-connection key is the TCP connection ID rather than the client IP address. This still provides meaningful isolation since each TCP connection gets a separate budget. A future upgrade to jsonrpsee 0.25+ could enable true per-IP keying.

This caused transactions with generous gas limits to be over-represented in the reward percentile distribution regardless of actual gas consumption, producing biased fee suggestions for wallets and gas estimators. Also adds input validation for reward percentiles: values outside [0, 100] or in non-monotonic order now return an INVALID_PARAMS error instead of being silently clamped.

Every deletion was verified with a full codebase grep before removal. Deleted zero-caller functions: - RevmExecutor::config() - ExecutionConfig::with_base_fee_params() - BlockContext::base_fee() - TxValidator::with_blob_base_fee() - RpcServer::with_cors() - TransactionPool::get() Removed unused re-exported constants from executor/src/lib.rs: - ACCESS_LIST_ADDRESS_GAS, ACCESS_LIST_STORAGE_KEY_GAS, MAX_BLOBS_PER_TX, TX_BASE_GAS, TX_CREATE_GAS, TX_DATA_NON_ZERO_GAS, TX_DATA_ZERO_GAS, TxValidator, ValidatedTx (all have zero external importers; the txpool has its own copies of these constants) Removed unused types from rpc/src/types.rs: - SyncStatus enum and SyncInfo struct (eth_syncing returns bool, not these types; only exercised in their own unit tests) Cleaned up FinalizationError in reporters/src/lib.rs: - Removed MissingParentSnapshot and ParentSnapshotEvicted variants (never constructed; the missing-parent case is handled via warn+restore instead) - Removed #[allow(dead_code)] since all remaining variants are now constructed Closes #298 Co-Authored-By: Claude Opus 4.6 * fix(executor): remove dead validation module The commit that removed the pub use re-exports from lib.rs left behind the `mod validation;` declaration and the entire validation.rs file. With no re-exports and no crate-internal consumers, all items in the module are dead code, triggering 21 Clippy errors (dead_code and unreachable_pub) on nightly. Remove the module declaration and delete the file entirely. Co-Authored-By: Claude Opus 4.6 * fix(executor): remove unused alloy-rlp dep and trailing blank line The previous commit removed the validation module but left behind the alloy-rlp dependency (causing clippy unused_crate_dependencies error) and a trailing blank line in lib.rs (causing rustfmt failure).

This made QMDB write failures completely invisible — no log, no metric, no error propagation. Changes: - Add `commit_failed: Arc` to QmdbHandle as a side-channel for the infallible DatabaseCommit trait - Log at error level and set the flag when DatabaseCommit fails - Add `take_commit_failure()` method to QmdbHandle to check and clear the flag - Add `take_commit_failure()` to StateDbRead trait with default `false` implementation; override in QmdbHandle to check the atomic flag - Add `ExecutionError::StateCommit` variant for surfacing the failure - Check the flag in RevmExecutor::execute() after the transaction loop and return ExecutionError::StateCommit if set Closes #258 Co-Authored-By: Claude Opus 4.6 * fix(storage): resolve CI failures in DatabaseCommit error surfacing - Fix private field access: add pub(crate) mark_commit_failed() method to QmdbHandle instead of directly accessing the private commit_failed field from adapter.rs (E0616) - Remove unused StateDbRead import from revm.rs (clippy) - Fix rustfmt formatting for .insert() calls in adapter.rs and qmdb.rs Co-Authored-By: Claude Opus 4.6 * fix(rpc): handle ExecutionError::StateCommit in RPC error mapping The new StateCommit variant added to ExecutionError was not covered in the exhaustive match inside execution_error_to_rpc, causing Build, Clippy, and Test CI to fail with E0004.

Previously, every state access during EVM execution called block_in_place, which blocked a tokio worker thread. With only 2 default worker threads, this meant 50% of async capacity was unavailable for consensus, networking, and RPC during block execution. The fix wraps executor.execute() calls in spawn_blocking at three sites: - build_block in app.rs (block proposal path) - BlockExecution::execute in execution.rs (verification + finalization) - build_proposal_async in proposal.rs (async proposal builder) Inside a spawn_blocking thread, the adapter's block_in_place call is a no-op (tokio >= 1.28), and Handle::block_on safely drives the state DB futures without occupying any async worker. All cloned values (executor, state, context, txs) are cheap: RevmExecutor is a small struct, OverlayState uses Arc, and BlockContext is a lightweight header wrapper.

This meant a malicious leader could propose blocks with non-increasing or far-future timestamps without rejection. Add two timestamp checks to `verify_block()` in app.rs: 1. Monotonicity: block timestamp must be strictly greater than the parent timestamp (matching the contract in `Block::next_timestamp`). 2. Future-drift: block timestamp must not exceed the validator's wall-clock time by more than 15 seconds. The parent timestamp is threaded through the verify chain: the `verify()` method captures the already-verified parent's timestamp from the ancestry stream and tracks it across the oldest-to-newest verification loop. Both checks are skipped during catch-up mode (certificate-trusted blocks).

Watchdog: `Error::Closed` now returns instead of calling `abort()`. When SIGTERM fires, the runtime drops all contexts, which resolves watched handles with `Error::Closed`. Previously this raced to `std::process::abort()` (SIGABRT / exit 134), bypassing all cleanup. Now the watchdog recognizes this as normal shutdown and returns cleanly. 2. Signal handler: adds a 200ms grace window after the shutdown signal so in-flight QMDB commits and log drains can complete before the runtime tears down task contexts. 3. RPC handles: `drop(rpc.start())` immediately cancelled both the HTTP and JSON-RPC server tasks. Changed to `let _rpc_handle = rpc.start()` so the handle lives until the enclosing scope returns, keeping RPC alive during normal operation and stopping it cleanly on shutdown.

The gauges are updated on every finalized block in the FinalizedReporter, giving continuous visibility into snapshot store health. - Add InMemorySnapshotStore::unpersisted_count() with unit test - Add LedgerView/LedgerService::snapshot_store_stats() accessor - Register both gauges in AppMetrics - Wire gauge updates in handle_finalized_update after each finalization Co-Authored-By: Claude Opus 4.6 * style: fix rustfmt formatting in ledger and reporters tests Apply cargo fmt formatting to setup_ledger calls in ledger tests and Block::new/assert_eq! calls in reporters tests to pass CI format check.

A correct calculate_base_fee() existed but was never called during block construction. This wires the existing function into all block production and verification paths so the base fee adjusts dynamically based on parent block gas usage per the EIP-1559 algorithm. Changes: - RevmApplication: add block_fees cache to track per-block gas_used and base_fee_per_gas keyed by consensus digest; seed genesis on startup - block_context() now takes parent_digest and computes the base fee via calculate_base_fee() from the cached parent gas data - build_block/verify_block record each block's fee data after execution - RevmContextProvider (finalization path): look up parent block from the BlockIndex to compute dynamic base fee for re-execution - replay_finalized_block: re-index blocks with real gas_used from execution so subsequent replay blocks derive correct base fees - seed_block_fee_cache: populate the fee cache from the BlockIndex after restart recovery so the first new blocks use correct base fees Closes #260 Co-Authored-By: Claude Opus 4.6 * fix(runner): clone block_index Arc before move and fix rustfmt formatting The block_index Arc was moved into with_block_index() and then borrowed later in seed_block_fee_cache(), causing E0382.

This caused browsers to block all cross-origin requests to the JSON-RPC endpoint, making browser-based dApps unable to interact with the node. Apply the same CORS layer to the jsonrpsee server via set_http_middleware() in both RpcServer::start() and JsonRpcServer::start(). Add a cors_config field and with_cors() builder method to JsonRpcServer for parity with RpcServer. Closes #263 Co-Authored-By: Claude Opus 4.6 * fix(rpc): use tower 0.4 ServiceBuilder for jsonrpsee set_http_middleware jsonrpsee 0.24 depends on tower 0.4, so its `set_http_middleware` method expects a `tower::ServiceBuilder` from tower 0.4. The crate also depends on tower 0.5 (for `ConcurrencyLimitLayer` and other middleware), which causes a type mismatch when tower 0.5's `ServiceBuilder` is passed to jsonrpsee's API. Add a renamed `tower_04` dependency (tower 0.4) and use `tower_04::ServiceBuilder` specifically for the two `set_http_middleware` call sites. The `CorsLayer` from tower-http 0.6 works with both tower versions since they share the same `tower-layer` 0.3.x types. Co-Authored-By: Claude Opus 4.6 * chore: regenerate Cargo.lock Co-Authored-By: Claude Opus 4.6 * fix: reset Cargo.lock to main (revert over-eager lockfile regeneration) The previous `cargo generate-lockfile` upgraded commonware-cryptography from 2026.4.0 to 2026.5.0, breaking the `From` impl and triggering RUSTSEC-2025-0055. Reset to main's lockfile which already contains tower 0.4.13; the only delta is wiring it into kora-rpc.
