for collecting canonical **head** (non-finalized) blockchain data from multiple beacon nodes with high availability (HA) support. Unlike Cannon which processes finalized epochs, Horizon operates at the chain head, subscribing to real-time beacon node SSE events and deriving structured data from head blocks. + +The module addresses the challenge of reliably collecting head data across distributed beacon node infrastructure while ensuring: +- **No duplicate events**: When connected to 10 beacon nodes all reporting the same block, only one set of derived events is emitted +- **No missed blocks**: A consistency fill iterator guarantees every slot is processed, even if SSE events are dropped +- **Immediate head tracking**: After downtime, the module immediately resumes head tracking rather than waiting for backfill to complete +- **HA deployment**: Multiple Horizon instances can run safely with coordinator-based state sharing + +## Goals + +- Derive the same event types as Cannon (beacon blocks, attestations, slashings, deposits, withdrawals, etc.) but for head data instead of finalized data +- **Use identical event types as Cannon** - xatu-server routes events by `MODULE_NAME` (HORIZON vs CANNON), not event type +- Support connecting to multiple upstream beacon nodes simultaneously +- Provide local deduplication to prevent emitting duplicate events when the same block is reported by multiple beacon nodes +- Enable HA deployments where multiple Horizon instances coordinate via the existing Coordinator service +- Implement a dual-iterator design: HEAD iterator for real-time data + FILL iterator for consistency catch-up +- Ensure the FILL iterator never blocks HEAD processing - they operate independently +- Achieve feature parity with Cannon's 13 derivers for head data +- **Refactor derivers into shared package** - both Cannon and Horizon use the same deriver implementations +- **End-to-end validation** - verified working with Kurtosis ethereum-package and all consensus clients + +## User Stories + +### US-001: Create Horizon module skeleton and CLI command +**Description:** As an operator, I want to run Xatu in "horizon" mode so that I can collect head data from my beacon nodes. + +**Acceptance Criteria:** +- [ ] New `pkg/horizon/` directory structure mirrors Cannon's organization +- [ ] `cmd/horizon.go` command added to CLI with `xatu horizon` subcommand +- [ ] Basic configuration loading with YAML support +- [ ] Metrics server starts on configured address +- [ ] Module logs startup message with version and instance ID +- [ ] Graceful shutdown on SIGTERM/SIGINT +- [ ] Typecheck/lint passes + +### US-002: Multi-beacon node connection

+- [ ] Configuration accepts array of beacon node URLs with optional headers +- [ ] Each beacon node connection is established independently +- [ ] Health checking per beacon node with configurable interval +- [ ] Failed connections are retried with exponential backoff +- [ ] Metrics track connection status per beacon node +- [ ] At least one healthy beacon node required to operate +- [ ] Typecheck/lint passes + +### US-003: SSE event subscription for head blocks +**Description:** As a data collector, I want Horizon to subscribe to beacon node block events so that I receive real-time notifications of new head blocks. + +**Acceptance Criteria:** +- [ ] Subscribe to `/eth/v1/events?topics=block` SSE stream on each beacon node +- [ ] Handle SSE reconnection on connection loss +- [ ] Parse block event payload (slot, block root, execution_optimistic flag) +- [ ] Route block events to deduplication layer +- [ ] Metrics track events received per beacon node +- [ ] Typecheck/lint passes + +### US-004: Local deduplication by block root +**Description:** As a data collector, I want Horizon to deduplicate block events locally so that the same block reported by multiple beacon nodes only triggers derivation once. + +**Acceptance Criteria:** +- [ ] TTL-based cache keyed by block root (configurable TTL, default 2 epochs / ~13 minutes) +- [ ] First block event for a root triggers derivation +- [ ] Subsequent events for the same root within TTL are dropped +- [ ] Cache cleanup runs periodically to prevent memory growth +- [ ] Metrics track cache hits/misses and deduplication rate +- [ ] Typecheck/lint passes + +### US-005: Coordinator-based slot location tracking +**Description:** As an operator running multiple Horizon instances, I want them to share state via the Coordinator so that they don't process the same slots. + +**Acceptance Criteria:** +- [ ] New `HorizonLocation` protobuf message with HEAD and FILL slot markers +- [ ] `GetHorizonLocation` and `UpsertHorizonLocation` Coordinator RPC methods +- [ ] Location tracked per deriver type and network (similar to Cannon) +- [ ] Atomic location updates to prevent race conditions +- [ ] Metrics expose current HEAD and FILL slot positions +- [ ] Typecheck/lint passes + +### US-006: HEAD iterator for real-time slot processing +**Description:** As a data collector, I want a HEAD iterator that processes slots as they arrive so that I immediately capture head data. + +**Acceptance Criteria:** +- [ ] HEAD iterator receives slot notifications from SSE deduplication layer +- [ ] HEAD iterator fetches full block data for the slot +- [ ] HEAD iterator passes block to derivers for event extraction +- [ ] HEAD iterator updates coordinator location after successful derivation +- [ ] HEAD iterator operates independently from FILL iterator +- [ ] HEAD iterator can skip slots if they've already been processed (race with FILL) +- [ ] Typecheck/lint passes + +### US-007: FILL iterator for consistency catch-up +**Description:** As an operator, I want a FILL iterator that ensures no slots are missed so that I have complete data even if SSE events are dropped. + +**Acceptance Criteria:**

processed before fetching +- [ ] FILL iterator has configurable batch size for efficiency +- [ ] FILL iterator has rate limiting to avoid overwhelming beacon nodes +- [ ] FILL iterator updates coordinator location after successful derivation +- [ ] Typecheck/lint passes + +### US-008: Dual-iterator coordination +**Description:** As an operator, I want HEAD and FILL iterators to coordinate so that HEAD always takes priority and they don't duplicate work. + +**Acceptance Criteria:** +- [ ] HEAD iterator has priority - FILL never blocks HEAD processing +- [ ] Separate location markers in coordinator: `head_slot` and `fill_slot` +- [ ] On startup, HEAD iterator immediately begins tracking new blocks +- [ ] On startup, FILL iterator begins from `fill_slot` toward `HEAD - LAG` +- [ ] Both iterators skip slots marked as processed by the other +- [ ] Configurable bounded range for FILL (e.g., never fill more than N slots back) +- [ ] Typecheck/lint passes + +### US-009: Refactor derivers to shared package +**Description:** As a developer, I want derivers shared between Cannon and Horizon so that we maintain a single source of truth for derivation logic. + +**Acceptance Criteria:** +- [ ] Create new `pkg/cldata/` package for shared consensus layer data derivation +- [ ] Move block fetching and parsing logic to shared package +- [ ] Move all 13 deriver implementations to shared package +- [ ] Derivers accept an iterator interface (epoch-based for Cannon, slot-based for Horizon) +- [ ] Derivers accept a context provider interface for client metadata +- [ ] Cannon

Clean up old Cannon deriver directory Remove v1/ and v2/ directories now that all derivers are in pkg/cldata/: - Remove pkg/cannon/deriver/beacon/eth/v1/ (beacon_blob, beacon_committee, beacon_validators, proposer_duty) - Remove pkg/cannon/deriver/beacon/eth/v2/ (attester_slashing, beacon_block, bls_to_execution_change, deposit, elaborated_attestation, execution_transaction, proposer_slashing, voluntary_exit, withdrawal) - Move adapters.go to pkg/cannon/deriver/adapters.go (used to bridge Cannon types to shared cldata interfaces) - Update event_deriver.go to reference only cldata shared derivers - Simplify config.go with unified DeriverConfig type This cleanup removes ~4,900 lines of code that was duplicated in the shared pkg/cldata package. --- pkg/cannon/cannon.go | 79 ++- .../deriver/{beacon/eth/v2 => }/adapters.go | 2 +- pkg/cannon/deriver/beacon/eth/v1/CLAUDE.md | 6 -

Adds `HORIZON_XATU_COORDINATOR_AUTHORIZATION` override for setting coordinator authorization secrets. 2. Implements a `BlockEventBroadcaster` to deduplicate block events before distribution. 3. Refactors block event consumption to use a `DualIterator` which multiplexes HEAD and FILL logic, replacing direct HeadIterator usage. 4. Adds configuration for iterator settings and a startup timeout for beacon nodes in `horizon.yaml`. 5. Adds reorg tracking and rollback logic for block-based derivers to maintain consistency after chain reorganizations. 6. Updates E2E tests to configure Kurtosis devnet with custom genesis time and disables future forks for stability. --- cmd/horizon.go | 27 ++++ deploy/kurtosis/horizon-test.yaml | 1 - deploy/kurtosis/xatu-horizon.yaml | 6 + docs/horizon.md | 3 +- example_horizon.yaml | 4 + pkg/horizon/block_broadcaster.go | 113 ++++++++++++++ pkg/horizon/config.go | 17 +++ pkg/horizon/ethereum/beacon.go | 12 +- pkg/horizon/ethereum/config.go | 6 + pkg/horizon/horizon.go | 101 +++++++++++-- pkg/horizon/iterator/dual.go | 235 ++++++++++++++++++++++++++++++ pkg/horizon/iterator/epoch.go | 78 +++++----- pkg/horizon/iterator/fill.go | 143 ++++++++++-------- pkg/horizon/iterator/head.go | 134 ++++++++--------- pkg/horizon/overrides.go | 4 + pkg/horizon/reorg_helpers.go | 102 +++++++++++++ pkg/horizon/reorg_labels.go | 81 ++++++++++ pkg/horizon/reorg_tracker.go | 74 ++++++++++ scripts/e2e-horizon-test.sh | 117 +++++++++++++-- 19 files changed, 1056 insertions(+), 202 deletions(-) create mode 100644 pkg/horizon/block_broadcaster.go create mode 100644 pkg/horizon/iterator/dual.go create mode 100644 pkg/horizon/reorg_helpers.go create mode 100644 pkg/horizon/reorg_labels.go create mode 100644 pkg/horizon/reorg_tracker.go diff --git a/cmd/horizon.go b/cmd/horizon.go index 64b6f85d7..5b7a32fc0 100644 --- a/cmd/horizon.go +++ b/cmd/horizon.go @@ -63,6 +63,15 @@ var HorizonOverrides = []HorizonOverride{ overrides.XatuOutputAuth.Value = val }, }), + createHorizonOverride(HorizonOverrideConfig{ + FlagName: "horizon-xatu-coordinator-authorization", + EnvName: "HORIZON_XATU_COORDINATOR_AUTHORIZATION", + Description: "sets the authorization secret for coordinator requests", + OverrideFunc: func(val string, overrides *horizon.Override) { + overrides.CoordinatorAuth.Enabled = true + overrides.CoordinatorAuth.Value = val + }, + }), createHorizonOverride(HorizonOverrideConfig{ FlagName: "metrics-addr", EnvName: "METRICS_ADDR", @@ -72,6 +81,24 @@ var HorizonOverrides = []HorizonOverride{ overrides.MetricsAddr.Value = val }, }), + createHorizonOverride(HorizonOverrideConfig{ + FlagName: "horizon-beacon-node-url", + EnvName: "HORIZON_BEACON_NODE_URL", + Description: "sets a single beacon node URL (overrides configured list)", + OverrideFunc: func(val string, overrides *horizon.Override) { + overrides.BeaconNodeURLs.Enabled = true + overrides.BeaconNodeURLs.Value = val + }, + }), + createHorizonOverride(HorizonOverrideConfig{ + FlagName: "horizon-network-name", + EnvName: "HORIZON_NETWORK_NAME", + Description: "overrides the network name detected from the beacon node", + OverrideFunc: func(val string, overrides *horizon.Override) { + overrides.NetworkName.Enabled = true + overrides.NetworkName.Value = val + }, + }), } // horizonCmd represents the horizon command diff --git a/deploy/kurtosis/horizon-test.yaml b/deploy/kurtosis/horizon-test.yaml index 55733afee..90eb5e3a4 100644 --- a/deploy/kurtosis/horizon-test.yaml +++ b/deploy/kurtosis/horizon-test.yaml @@ -72,4 +72,3 @@ global_log_level: info # Port publishing disabled - we'll use docker network for connectivity port_publisher: nat_exit_ip: KURTOSIS_IP_ADDR_PLACEHOLDER - public_port_start: 32000 diff --git a/deploy/kurtosis/xatu-horizon.yaml b/deploy/kurtosis/xatu-horizon.yaml index 3e93c0ad2..75a07cc31 100644 --- a/deploy/kurtosis/xatu-horizon.yaml +++ b/deploy/kurtosis/xatu-horizon.yaml @@ -35,6 +35,12 @@ coordinator: # Multi-beacon node pool - all 6 consensus clients # Update these URLs after starting the Kurtosis network ethereum: + # Override network name for Kurtosis devnet + overrideNetworkName: kurtosis + + # Allow extra time for clients to become healthy after genesis + startupTimeout: 5m + beaconNodes: # Lighthouse - name: lighthouse diff --git a/docs/horizon.md b/docs/horizon.md index 4f0addea2..594e0f961 100644 --- a/docs/horizon.md +++ b/docs/horizon.md @@ -116,7 +116,7 @@ Horizon uses a dual-iterator architecture to ensure both real-time data collecti - **Priority**: Highest - never blocks, processes events immediately - **Location Tracking**: Updates `head_slot` in coordinator after processing each slot -### FILL Iterator (Planned) +### FILL Iterator - **Purpose**: Catches up on any missed slots between restarts - **Mechanism**: Walks slots from `fill_slot` toward `HEAD - LAG` - **Configuration**: @@ -301,6 +301,7 @@ Horizon requires a single `yaml` config file.

Unlike Cannon which processes finalized epochs, Horizon operates at the chain head, subscribing to real-time beacon node SSE events and deriving structured data from head blocks. - -The module addresses the challenge of reliably collecting head data across distributed beacon node infrastructure while ensuring: -- **No duplicate events**: When connected to 10 beacon nodes all reporting the same block, only one set of derived events is emitted -- **No missed blocks**: A consistency fill iterator guarantees every slot is processed, even if SSE events are dropped -- **Immediate head tracking**: After downtime, the module immediately resumes head tracking rather than waiting for backfill to complete -- **HA deployment**: Multiple Horizon instances can run safely with coordinator-based state sharing - -## Goals - -- Derive the same event types as Cannon (beacon blocks, attestations, slashings, deposits, withdrawals, etc.) but for head data instead of finalized data -- **Use identical event types as Cannon** - xatu-server routes events by `MODULE_NAME` (HORIZON vs CANNON), not event type -- Support connecting to multiple upstream beacon nodes simultaneously -- Provide local deduplication to prevent emitting duplicate events when the same block is reported by multiple beacon nodes -- Enable HA deployments where multiple Horizon instances coordinate via the existing Coordinator service -- Implement a dual-iterator design: HEAD iterator for real-time data + FILL iterator for consistency catch-up -- Ensure the FILL iterator never blocks HEAD processing - they operate independently -- Achieve feature parity with Cannon's 13 derivers for head data -- **Refactor derivers into shared package** - both Cannon and Horizon use the same deriver implementations -- **End-to-end validation** - verified working with Kurtosis ethereum-package and all consensus clients - -## User Stories - -### US-001: Create Horizon module skeleton and CLI command -**Description:** As an operator, I want to run Xatu in "horizon" mode so that I can collect head data from my beacon nodes. -

-### HEAD Iterator -- FR-14: HEAD iterator MUST process slots immediately when SSE events arrive -- FR-15: HEAD iterator MUST fetch full block data from any healthy beacon node -- FR-16: HEAD iterator MUST pass blocks to all enabled derivers -- FR-17: HEAD iterator MUST update coordinator location after derivation -- FR-18: HEAD iterator MUST skip slots already processed by FILL iterator -

- Beacon node pool metrics (node status, blocks fetched, cache hits/misses) - - SSE subscription metrics (events, connection status, delays) - - Reorg metrics (events, depth histogram, ignored, last event tracking) - - Deduplication cache metrics (hits, misses, size) - - Iterator metrics (HEAD, FILL, Epoch) with processed/skipped/position tracking - - Usage section with CLI flags and docker/build/dev run commands - - Minimal and production configuration examples -- Files changed: - - docs/horizon.md (new - 549 lines) -- **Learnings for future iterations:** - - Follow existing docs pattern: Table of contents, Usage, Requirements, Configuration, Running Locally - - Use markdown tables for configuration options (Name, Type, Default, Description columns) - - ASCII art diagrams are effective for architecture visualization - - Metrics reference should be organized by component/category for easier lookup - - Include both minimal and production config examples for different use cases - - Cross-reference related docs (e.g., cannon.md for output sink details) - - Use comparison tables when contrasting similar modules (when to use which) ---- - -## 2026-01-21 - US-034 - -- What was implemented: - - Added xatu-horizon service to docker-compose.yml with "horizon" profile - - Service follows same pattern as xatu-cannon with environment variables for configuration overrides - - Created deploy/local/docker-compose/xatu-horizon.yaml with full Horizon configuration: - - Multi-beacon node support (single node placeholder, configurable via HORIZON_BEACON_NODE_URL) - - Coordinator config pointing to xatu-server:8080 - - DedupCache, Subscription, Reorg, EpochIterator configs - - All 13 derivers enabled (9 block-based + 4 epoch-based) - - Output sink to xatu-server - - Added horizon and horizon-vals output handlers to xatu-server.yaml: -

- docker-compose profiles allow optional services: --profile horizon to include xatu-horizon - - xatu-server routing uses module filters (HORIZON vs CANNON) to separate traffic - - Same event types (BEACON_API_*) can come from different modules, filter by module name - - Config file naming convention: xatu-.yaml in deploy/local/docker-compose/ - - Environment variable naming convention: HORIZON_* for horizon service overrides ---- - -## 2026-01-21 - US-035 - -- What was implemented: - - Created deploy/kurtosis/ directory for E2E testing configuration - - Created horizon-test.yaml with ethereum-package config for all 6 consensus clients: - - Lighthouse + Geth - - Prysm + Nethermind - - Teku + Erigon - - Lodestar + Reth - - Nimbus + Besu - - Grandine + Geth - - Created xatu-horizon.yaml with Horizon config for connecting to all beacon nodes - - Created xatu-server.yaml with server config for E2E test event routing - - Created README.md with comprehensive documentation: - - Architecture diagram showing Kurtosis network + Xatu stack integration - - Step-by-step setup instructions - - Network connectivity instructions - - Validation queries for ClickHouse - - Cleanup commands -- Files changed: - - deploy/kurtosis/horizon-test.yaml (new - ethereum-package config) - - deploy/kurtosis/xatu-horizon.yaml (new - Horizon multi-beacon config) - - deploy/kurtosis/xatu-server.yaml (new - server E2E config) - - deploy/kurtosis/README.md (new - E2E test documentation) -- **Learnings for future iterations:** - - Kurtosis E2E tests follow pattern from sentry smoke test: separate Kurtosis network + docker-compose xatu stack - - ClickHouse setup is provided by main docker-compose.yml, not duplicated in Kurtosis config - - Beacon node URLs in Kurtosis follow pattern: cl--: (e.g., cl-lighthouse-geth:4000) - - Prysm uses port 3500 by default, other clients use 4000 - - Network connectivity between Kurtosis and docker-compose requires docker network connect - - ethereum-package config format: participants array with el_type, cl_type, count, optional extra_params ---- - - -## 2026-01-21 - US-036 - -- What was implemented: - - Created scripts/e2e-horizon-test.sh - automated E2E test script for Horizon - - Script orchestrates full E2E test lifecycle: - - Builds Xatu Docker image (unless --skip-build) - - Starts docker-compose stack (ClickHouse, Kafka, PostgreSQL, xatu-server) - - Spins up Kurtosis Ethereum testnet with all 6 consensus clients - - Waits for genesis (~120 seconds) - - Connects Kurtosis beacon node containers to xatu network - - Generates Horizon config dynamically with actual container names - - Starts Horizon container - - Waits for data collection (~2 epochs / ~15 minutes) - - Runs 7 validation queries against ClickHouse - - Reports pass/fail status with colored output - - Cleans up all resources on exit (unless --skip-cleanup) - - Script options: --quick (1 epoch), --skip-build, --skip-cleanup - - Validation queries check: beacon blocks, deduplication, slot gaps, execution transactions, elaborated attestations, proposer duties, beacon committees - - Updated deploy/kurtosis/README.md with Quick Start section and detailed Manual Test Procedure -- Files changed: - - scripts/e2e-horizon-test.sh (new - 400+ lines automated E2E test script) - - deploy/kurtosis/README.md (updated - Quick Start section, Manual Test Procedure) -- **Learnings for future iterations:** - - Follow sentry-smoke-test.yaml pattern for network bridging: connect Kurtosis containers to docker-compose network - - Kurtosis container names follow pattern: cl--- (e.g., cl-lighthouse-geth-001) - - Use `kurtosis enclave inspect ` to discover actual container names - - Generate Horizon config dynamically to avoid hardcoding container names - - Allow 60s buffer after epoch wait time for event processing through pipeline - - ClickHouse queries need FINAL keyword to see latest data after recent inserts - - Use trap for cleanup to ensure resources are freed even on script failure ---- - -## 2026-01-21 - US-037 - -- What was implemented: - - Created scripts/e2e-horizon-validate.sql with 8 comprehensive validation queries - - Query 1: Duplicate blocks check - detects if deduplication fails (should return empty) - - Query 2: Slot gaps check - detects FILL iterator issues (should return empty/minimal) - - Query 3: Module verification - confirms meta_client_module = 'HORIZON' - - Query 4: Events per deriver - counts all 13 deriver types (block-based + epoch-based) - - Query 5: Slot coverage summary - shows min/max/expected/actual slots and coverage % - - Query 6: Block latency analysis - avg/min/max processing latency in seconds - - Query 7: Events by node - confirms dedup (all events attributed to single Horizon instance) - - Query 8: Recent blocks - sanity check showing 10 most recent slots - - Query 9: Validation summary - automated pass/fail check for CI (all should return 1) - - Updated deploy/kurtosis/README.md with Expected Results section documenting each query -- Files changed: - - scripts/e2e-horizon-validate.sql (new - 200+ lines of validation queries) - - deploy/kurtosis/README.md (updated - added Expected Results section with detailed explanations) -- **Learnings for future iterations:** - - Use FINAL keyword in ClickHouse queries to see latest data from ReplacingMergeTree tables - - lagInFrame() with OVER (ORDER BY slot) for gap detection in ClickHouse - - Validation summary query uses boolean expressions for automated pass/fail - - Expected counts help operators understand what "normal" looks like for each deriver - - Separate SQL file makes queries reusable and easier to maintain than inline in scripts ---- From 80655b65cf7737e09e1126061b1bac5b75b1950d Mon Sep 17 00:00:00 2001 From: Sam Calder-Mason Date: Fri, 23 Jan 2026 13:53:03 +1000 Subject: [PATCH 63/64] refactor(cldata): implement registry-based deriver pattern Replace verbose individual deriver implementations with a declarative registry pattern that eliminates boilerplate code. Changes: - Add registry.go for declarative deriver specifications - Add generic.go as universal deriver handling run loop, backoff, tracing - Add event_builder.go for common event creation logic - Add factory.go for creating derivers from registry - Add extractors/ package with 13 focused extractor functions - Update horizon.go to use factory pattern (~110 -> 35 lines) - Update cannon.go to use factory pattern (~280 -> 55 lines) - Remove 13 verbose deriver files (~5500 lines deleted) Code reduction: ~75-80% for simple derivers, ~60-70% for complex ones. --- pkg/cannon/cannon.go | 331

[Kurtosis](https://docs.kurtosis.com/install/) installed -2. Docker and Docker Compose installed -3. Xatu Docker image built: `docker build -t ethpandaops/xatu:local .` - -## Running the E2E Test - -### Step 1: Start the Xatu Stack - -From the repository root: - -```bash -# Start all xatu infrastructure (ClickHouse, Kafka, PostgreSQL, etc.) -docker compose up --detach -``` - -### Step 2: Start the Kurtosis Network - -```bash -kurtosis run github.com/ethpandaops/ethereum-package \ - --args-file deploy/kurtosis/horizon-test.yaml \ - --enclave horizon -``` - -### Step 3: Get Beacon Node URLs - -After Kurtosis starts, get the actual service URLs: - -```bash -kurtosis enclave inspect horizon | grep -E "cl-.+-http" -``` - -Update the `xatu-horizon.yaml` file with the actual URLs, or set environment variables. - -### Step 4: Connect Networks - -Connect the Kurtosis containers to the xatu-net docker network: - -```bash -# Get the Kurtosis network name -KURTOSIS_NETWORK=$(docker network ls | grep horizon | awk '{print $2}') - -# Connect xatu containers to Kurtosis network (for beacon node access) -docker network connect $KURTOSIS_NETWORK xatu-server -docker network connect $KURTOSIS_NETWORK xatu-horizon -``` - -Or connect Kurtosis containers to xatu-net: - -```bash -for container in $(kurtosis enclave inspect horizon | grep cl- | awk '{print $1}'); do - docker network connect xatu_xatu-net $container -done -``` - -### Step 5: Start Horizon - -Start Horizon with the Kurtosis configuration: - -```bash -docker compose --profile horizon up xatu-horizon -``` - -Or run locally: - -```bash -xatu horizon --config deploy/kurtosis/xatu-horizon.yaml -``` - -### Step 6: Verify Data in ClickHouse - -Query ClickHouse to verify Horizon is producing data: - -```bash -docker exec xatu-clickhouse-01 clickhouse-client --query " - SELECT - meta_client_name, - COUNT(*) as events - FROM default.beacon_api_eth_v2_beacon_block - WHERE meta_client_module = 'HORIZON' - GROUP BY meta_client_name -" -``` - -## Validation Queries - -A comprehensive set of validation queries is available in `scripts/e2e-horizon-validate.sql`.

Despite receiving SSE events from multiple beacon nodes, Horizon's dedup cache ensures only one event per block is processed. - -### Query 2: Slot Gaps Check -**Expected:** Empty or minimal results - -Large gaps (>1 slot) between consecutive blocks indicate the FILL iterator may not be catching up properly. However, some gaps are acceptable: -- Gaps of 1 slot are normal (consecutive slots) -- Gaps may occur for genuinely missed blocks (no proposer) -- During initial sync, gaps are expected until FILL catches up - -### Query 3: Module Verification -**Expected:** All rows have `meta_client_module = 'HORIZON'` - -This confirms events were generated by the Horizon module and not by Cannon or other sources. - -### Query 4: Events Per Deriver -**Expected counts after 2 epochs:** - -| Event Type | Expected Count | Notes | -|------------|---------------|-------| -| beacon_block | ~64 | 32 slots/epoch × 2 epochs | -| elaborated_attestation | >1000 | Multiple attestations per block | -| execution_transaction | 0+ | Depends on test network activity | -| proposer_duty | ~64 | One duty per slot | -| beacon_committee | >100 | Multiple committees per epoch | -| beacon_validators | >0 | Chunked validator states | -| attester_slashing | 0 | Rare event, typically 0 | -| proposer_slashing | 0 | Rare event, typically 0 | -| deposit | 0+ | Only if deposits occur | -| withdrawal | 0+ | Only if withdrawals enabled | -| voluntary_exit | 0 | Rare event, typically 0 | -| bls_to_execution_change | 0 | Rare event, typically 0 | -| beacon_blob | 0+ | Deneb+ only, depends on blob txs | - -### Query 5: Slot Coverage -**Expected:** -- `coverage_percent` > 90% -- `actual_slots` close to `expected_slots` - -If coverage is significantly below 100%, check: -1. The FILL iterator is running -2. The LAG setting isn't too large -3. No beacon node connectivity issues - -### Query 6: Block Latency -**Expected:** -- `avg_latency_seconds` < 30s for real-time blocks -- `min_latency_seconds` should be low (< 5s) for HEAD-processed blocks -- `max_latency_seconds` may be higher for FILL-processed blocks - -### Query 7: Events by Node -**Expected:** All events attributed to Horizon instance name (e.g., `horizon-e2e-test`) - -Events from all beacon nodes should be deduplicated into a single stream. The `meta_client_name` should match the configured Horizon instance name. - -### Query 8: Recent Blocks -**Expected:** Shows the 10 most recent slots with block data - -Use this for quick visual verification that data is flowing. The `slot` values should be recent and increasing. - -### Validation Summary -**Expected:** All columns return `1` (true) - -| Check | Expected | Description | -|-------|----------|-------------| -| has_beacon_blocks | 1 | Beacon blocks are being collected | -| no_duplicates | 1 | Deduplication is working | -| has_attestations | 1 | Attestation deriver is working | -| has_proposer_duties | 1 | Proposer duty deriver is working | -| has_committees | 1 | Committee deriver is working | -| good_coverage | 1 | >90% slot coverage | - -If any check returns `0`, investigate the specific deriver or component. - -## Cleanup - -```bash -# Stop Kurtosis network -kurtosis enclave stop horizon -kurtosis enclave rm horizon - -# Stop xatu stack -docker compose down -v -``` - -## Consensus Clients Tested - -| Client | EL Pair | Beacon API Port | -|------------|------------|-----------------| -| Lighthouse | Geth | 4000 | -| Prysm | Nethermind | 3500 | -| Teku | Erigon | 4000 | -| Lodestar | Reth | 4000 | -| Nimbus | Besu | 4000 | -| Grandine | Geth | 4000 | - -## Manual Test Procedure - -For debugging or step-by-step execution, follow this manual procedure: - -### Step 1: Build the Xatu Image - -```bash -cd /path/to/xatu -docker build -t ethpandaops/xatu:local . -``` - -### Step 2: Start the Xatu Stack - -```bash -docker compose up --detach -``` - -Wait for all services to be healthy: -```bash -docker compose ps -``` - -### Step 3: Start the Kurtosis Network - -```bash -kurtosis run github.com/ethpandaops/ethereum-package \ - --args-file deploy/kurtosis/horizon-test.yaml \ - --enclave horizon-e2e -``` - -Wait for the network to start (this may take 2-3 minutes). - -### Step 4: Get Beacon Node Containers - -```bash -kurtosis enclave inspect horizon-e2e | grep -E "^cl-" | grep -v validator -``` - -### Step 5: Connect Networks - -Connect Kurtosis containers to the xatu network: - -```bash -for container in $(kurtosis enclave inspect horizon-e2e | grep -E "^cl-" | grep -v validator | awk '{print $1}'); do - docker network connect xatu_xatu-net "$container" 2>/dev/null || true - echo "Connected: $container" -done -``` - -### Step 6: Generate Horizon Config - -Create a config file with actual beacon node URLs: - -```bash -# Get container names -LIGHTHOUSE=$(kurtosis enclave inspect horizon-e2e | grep cl-lighthouse | grep -v validator | head -n1 | awk '{print $1}') -PRYSM=$(kurtosis enclave inspect horizon-e2e | grep cl-prysm | grep -v validator | head -n1 | awk '{print $1}') -TEKU=$(kurtosis enclave inspect horizon-e2e | grep cl-teku | grep -v validator | head -n1 | awk '{print $1}') -LODESTAR=$(kurtosis enclave inspect horizon-e2e | grep cl-lodestar | grep -v validator | head -n1 | awk '{print $1}') -NIMBUS=$(kurtosis enclave inspect horizon-e2e | grep cl-nimbus | grep -v validator | head -n1 | awk '{print $1}') -GRANDINE=$(kurtosis enclave inspect horizon-e2e | grep cl-grandine | grep -v validator | head -n1 | awk '{print $1}') - -echo "Beacon nodes:" -echo " Lighthouse: $LIGHTHOUSE" -echo " Prysm: $PRYSM" -echo " Teku: $TEKU" -echo " Lodestar: $LODESTAR" -echo " Nimbus: $NIMBUS" -echo " Grandine: $GRANDINE" -``` - -Update `deploy/kurtosis/xatu-horizon.yaml` with these container names. - -### Step 7: Start Horizon - -```bash -docker run -d \ - --name xatu-horizon \ - --network xatu_xatu-net \ - -v $(pwd)/deploy/kurtosis/xatu-horizon.yaml:/etc/xatu/config.yaml:ro \ - ethpandaops/xatu:local \ - horizon --config /etc/xatu/config.yaml -``` - -### Step 8: Monitor Progress - -Check Horizon logs: -```bash -docker logs -f xatu-horizon -``` - -Check block count in ClickHouse: -```bash -docker exec xatu-clickhouse-01 clickhouse-client --query " - SELECT COUNT(*) as blocks - FROM beacon_api_eth_v2_beacon_block FINAL - WHERE meta_client_module = 'HORIZON' -" -``` - -### Step 9: Run Validation Queries - -After waiting 2 epochs (~13 minutes), run the validation queries from the "Validation Queries" section above. - -### Step 10: Cleanup - -```bash -# Stop Horizon -docker stop xatu-horizon && docker rm xatu-horizon - -# Stop Kurtosis -kurtosis enclave stop horizon-e2e && kurtosis enclave rm horizon-e2e - -# Stop docker-compose -docker compose down -v -``` - -## Notes - -- The E2E test uses the main docker-compose.yml which includes ClickHouse with full schema migrations -- Horizon connects to all 6 beacon nodes simultaneously, testing the multi-beacon node pool functionality -- Block deduplication ensures only one event per block root despite receiving from multiple beacon nodes -- The coordinator tracks progress, allowing Horizon to resume from where it left off -- The automated script (`scripts/e2e-horizon-test.sh`) is recommended for CI/CD pipelines
