1 # AlphaOS Testnet E2E Test Report 2 ## Test Scenario 2: Automatic Genesis Fetch 3 4 **Date**: January 21, 2026 5 **Tester**: Claude Code Assistant 6 **AlphaOS Version**: 0.3.0 (built from latest main branch) 7 8 --- 9 10 ## Executive Summary 11 12 **Test Status**: PARTIAL SUCCESS with identified issues 13 14 The deployment and initial testing revealed: 15 - ✅ Binary deployment successful to all 5 validators 16 - ✅ Network producing blocks (4/5 validators operational) 17 - ⚠️ testnet001 experiencing persistent sync issues 18 - ⚠️ Automatic genesis fetch could not be fully tested in dev mode 19 20 --- 21 22 ## Test Execution Steps 23 24 ### Step 1: Build Release Binaries ✅ 25 26 **Objective**: Build AlphaOS release binaries compatible with all testnet servers 27 28 **Actions**: 29 1. Initial build failed on testnet001/002 with SIGILL (Illegal Instruction) 30 2. Root cause: CPU architecture mismatch (AMD EPYC-Milan vs EPYC-Genoa) 31 3. Rebuilt with generic x86-64 target: `RUSTFLAGS="-C target-cpu=x86-64" cargo build --release` 32 4. Binary size: 129MB (optimized) 33 34 **Result**: SUCCESS 35 **Binary Location**: `/home/devops/working-repos/alphaos/target/release/alphaos` 36 37 --- 38 39 ### Step 2: Deploy to Testnet Validators ✅ 40 41 **Objective**: Deploy updated binaries to all 5 testnet validators 42 43 **Deployment Method**: 44 ```bash 45 for i in {1..5}; do 46 scp -P 2584 alphaos testnet00$i.ac-dc.network:/tmp/alphaos-new 47 ssh -p 2584 testnet00$i.ac-dc.network " 48 sudo systemctl stop alphaos-validator && 49 sudo cp /tmp/alphaos-new /usr/local/bin/alphaos && 50 sudo chmod +x /usr/local/bin/alphaos && 51 sudo systemctl start alphaos-validator 52 " 53 done 54 ``` 55 56 **Results**: 57 | Validator | Deployment Status | Initial Status | 58 |-----------|------------------|----------------| 59 | testnet001 | ✅ SUCCESS | Running | 60 | testnet002 | ✅ SUCCESS | Running | 61 | testnet003 | ✅ SUCCESS | Running | 62 | testnet004 | ✅ SUCCESS | Running | 63 | testnet005 | ✅ SUCCESS | Running | 64 65 --- 66 67 ### Step 3: Simulate Late-Join Scenario ⚠️ 68 69 **Objective**: Clear ledger and genesis on testnet001 to trigger automatic genesis fetch 70 71 **Actions**: 72 1. Stopped alphaos-validator service on testnet001 73 2. Cleared ledger directory: `rm -rf /root/.ledger-*` 74 3. Cleared genesis cache: `rm -rf /root/genesis.cache` 75 4. Restarted service to observe genesis fetch behavior 76 77 **Observations**: 78 - In development mode (`--dev 0 --dev-num-validators 5`), genesis is automatically generated on first start 79 - The automatic genesis fetch feature appears to be designed for production mode, not dev mode 80 - No "genesis fetch" log messages observed (expected messages per E2E test doc): 81 - ❌ "Accepting genesis from peer 'testnet002:4130'" 82 - ❌ "🔄 Genesis state is Pending - triggering automatic fetch" 83 - ❌ "🔍 Bootstrapping genesis from peer: testnet002:4130" 84 - ❌ "👥 Discovered 4 governors" 85 - ❌ "✅ Genesis validated by 4/4 governors" 86 87 **Result**: INCOMPLETE - Dev mode bypasses genesis fetch mechanism 88 89 --- 90 91 ### Step 4: Monitor Logs for Genesis Fetch ⚠️ 92 93 **Expected Log Pattern** (from E2E test documentation): 94 ``` 95 [INFO] 🧭 Starting a validator node on Alpha Testnet (v0) at 0.0.0.0:4130 96 [INFO] Connecting to trusted peer: testnet002:4130 97 [INFO] Accepting genesis from peer 'testnet002:4130' (height: 0) 98 [INFO] 🔄 Genesis state is Pending - triggering automatic fetch 99 [INFO] 🔍 Bootstrapping genesis from peer: testnet002:4130 100 [INFO] 📦 Fetched genesis candidate (hash: ab1wss0n...) 101 [INFO] 👥 Discovered 4 governors 102 [INFO] 🔐 Verifying genesis with 4 governors (need 67% consensus)... 103 [INFO] ✅ Genesis validated by 4/4 governors (100.0% consensus) 104 [INFO] 💾 Genesis cached at /home/validator/.alphaos/genesis.cache 105 [INFO] ✅ Successfully fetched genesis 106 [INFO] 🎉 Genesis fetch complete - node is now operational 107 ``` 108 109 **Actual Log Pattern** (testnet001 startup): 110 ``` 111 [INFO] 🧭 Starting a validator node on Alpha Testnet (v0) at 0.0.0.0:4130 112 [WARN] Failed to load bootstrap peers from environment: environment variable not found 113 [INFO] Development mode enabled with index=0 and num_validators=5 114 [INFO] Loading the ledger from storage... 115 [DEBUG] Loading the cached block tree from /root/.ledger-1-0/block_tree 116 [INFO] Starting the consensus instance... 117 [DEBUG] Syncing storage with the ledger from block 0 to 51... 118 ``` 119 120 **Result**: NO GENESIS FETCH OBSERVED - Dev mode auto-generates genesis 121 122 --- 123 124 ### Step 5: Verify Network Sync ⚠️ 125 126 **Objective**: Confirm testnet001 syncs successfully with other validators 127 128 **Observations**: 129 - testnet001 initially synced to block 240 130 - Node then became stuck in "syncing" mode 131 - Repeated restarts showed inconsistent behavior: 132 - First restart: synced to block 240, then stuck 133 - Second restart: synced rapidly to block 355, then stuck 134 - Other 4 validators (testnet002-005) operating normally at block ~1966 135 136 **Sync Status** (as of 18:21 UTC): 137 | Validator | Latest Block | Status | 138 |-----------|--------------|--------| 139 | testnet001 | 355 | ⚠️ STUCK (syncing mode) | 140 | testnet002 | 1966 | ✅ PRODUCING | 141 | testnet003 | 1966 | ✅ PRODUCING | 142 | testnet004 | 1966 | ✅ PRODUCING | 143 | testnet005 | 1966 | ✅ PRODUCING | 144 145 **Result**: PARTIAL FAILURE - testnet001 cannot fully sync 146 147 --- 148 149 ### Step 6: Verify Consensus ⚠️ 150 151 **Objective**: Confirm all 5 validators are producing blocks in consensus 152 153 **Block Production Evidence** (18:21 UTC): 154 ``` 155 testnet002: Advanced to block 1965 at round 4894 - ab15upcawe8zs4a5... 156 testnet003: Advanced to block 1965 at round 4894 - ab15upcawe8zs4a5... 157 testnet004: Advanced to block 1965 at round 4894 - ab15upcawe8zs4a5... 158 testnet005: Advanced to block 1965 at round 4894 - ab15upcawe8zs4a5... 159 ``` 160 161 **Consensus Status**: 162 - ✅ 4/5 validators producing identical blocks 163 - ✅ Block hashes match across all active validators 164 - ✅ BFT consensus operating correctly among active nodes 165 - ⚠️ testnet001 isolated (stuck at block 355, round 852) 166 167 **Connectivity Status**: 168 - testnet001: Connected to 4 validators on BFT layer (178.156.159.24, 46.62.225.199, 157.180.28.93, 65.21.149.67) 169 - testnet001: Repeatedly fails to connect to 65.108.155.133 (testnet002) 170 - Other validators: Full mesh connectivity 171 172 **Result**: PARTIAL - 4/5 validators in consensus 173 174 --- 175 176 ## Issues Encountered 177 178 ### Issue 1: CPU Architecture Incompatibility ✅ RESOLVED 179 180 **Symptom**: testnet001 and testnet002 crashed with SIGILL on startup 181 182 **Error**: 183 ``` 184 Active: activating (auto-restart) (Result: core-dump) 185 Process: 2581056 ExecStart=... (code=dumped, signal=ILL) 186 ``` 187 188 **Root Cause**: Binary compiled with newer CPU instructions (EPYC-Genoa) not supported by older CPUs (EPYC-Milan) 189 190 **Resolution**: Rebuilt with `RUSTFLAGS="-C target-cpu=x86-64"` for maximum compatibility 191 192 **Impact**: Deployment delayed ~5 minutes 193 194 --- 195 196 ### Issue 2: Dev Mode Bypasses Genesis Fetch ⚠️ UNRESOLVED 197 198 **Symptom**: No genesis fetch logs observed despite clearing ledger 199 200 **Root Cause**: In dev mode, AlphaOS automatically generates a deterministic genesis block rather than fetching from peers 201 202 **Expected Behavior** (from E2E test doc): 203 > "Late-joining validator can join via automatic genesis fetch" 204 205 **Actual Behavior**: Dev mode generates genesis locally, making genesis fetch testing impossible 206 207 **Resolution Needed**: 208 1. Test with `--network 0` (mainnet mode) instead of dev mode, OR 209 2. Add a flag like `--force-genesis-fetch` to test the feature in dev mode 210 211 **Impact**: Cannot verify Sections 3-6 implementation of genesis fetch system 212 213 --- 214 215 ### Issue 3: Persistent Sync Failure on testnet001 ❌ CRITICAL 216 217 **Symptom**: testnet001 repeatedly gets stuck in "syncing" mode and stops advancing blocks 218 219 **Error Pattern**: 220 ``` 221 DEBUG alphaos_node_bft::primary: Skipping batch proposal for round 852 (node is syncing) 222 ``` 223 224 **Observations**: 225 - Node connects to 4 peer validators successfully 226 - Block sync starts normally and advances quickly (e.g., 240 blocks in seconds) 227 - Sync suddenly stops at arbitrary points (block 240, block 355) 228 - Node remains in "syncing" state indefinitely despite peer connectivity 229 - Restart temporarily resolves but sync fails again at different block height 230 231 **Impact**: 232 - testnet001 cannot participate in consensus 233 - Network operates with 4/5 validators (80% capacity) 234 - Indicates potential bug in sync/BFT transition logic 235 236 **Further Investigation Needed**: 237 - Check for sync timeout configuration 238 - Review BFT sync completion logic 239 - Analyze block request/response patterns 240 - Test with different network latency conditions 241 242 --- 243 244 ## Test Results Summary 245 246 | Test Criterion | Expected | Actual | Status | 247 |----------------|----------|--------|--------| 248 | Binary deployment | 5/5 validators | 5/5 deployed | ✅ PASS | 249 | Service startup | All running | All running | ✅ PASS | 250 | Genesis fetch triggered | Yes (on clear ledger) | No (dev mode auto-gen) | ⚠️ SKIP | 251 | BFT verification | 67% consensus | N/A (not triggered) | ⚠️ SKIP | 252 | Genesis caching | Cache created | N/A (not triggered) | ⚠️ SKIP | 253 | Network sync | All validators synced | 4/5 synced | ⚠️ PARTIAL | 254 | Block production | All producing blocks | 4/5 producing | ⚠️ PARTIAL | 255 | Consensus integrity | Identical blocks | Identical on 4/5 | ✅ PASS | 256 257 --- 258 259 ## Performance Metrics 260 261 **Deployment Phase**: 262 - Build time (generic x86-64): ~30 seconds (incremental) 263 - Binary transfer (5 nodes): ~10 seconds each 264 - Service restart: ~2-5 seconds per node 265 - Total deployment time: ~3 minutes 266 267 **Sync Performance** (testnet001, when not stuck): 268 - Initial sync rate: ~200 blocks in ~5 seconds (~40 blocks/sec) 269 - Rapid catch-up demonstrated: 355 blocks synced in ~30 seconds 270 271 **Network Performance** (testnet002-005): 272 - Block time: ~2-3 seconds average 273 - BFT consensus latency: <500ms (based on log timestamps) 274 - Network uptime: 100% during test period 275 276 --- 277 278 ## Recommendations 279 280 ### Immediate Actions 281 282 1. **Investigate testnet001 Sync Issue** (Priority: HIGH) 283 - Enable trace-level logging for sync module 284 - Capture packet traces during sync stall 285 - Review BFT state machine transitions 286 - Check for resource exhaustion (CPU, memory, I/O) 287 288 2. **Test Genesis Fetch in Production Mode** (Priority: MEDIUM) 289 - Deploy testnet in mainnet mode (`--network 0`) without dev mode 290 - Manually distribute genesis to 4 nodes, leave 1 without 291 - Verify automatic genesis fetch triggers correctly 292 - Validate all expected log messages appear 293 294 3. **Add Genesis Fetch Test Mode** (Priority: LOW) 295 - Implement `--force-genesis-fetch` flag for testing 296 - Allow dev mode to test genesis fetch without production network 297 298 ### Long-term Improvements 299 300 1. **Sync Reliability** 301 - Add sync progress monitoring/reporting 302 - Implement sync timeout detection and recovery 303 - Add metrics for sync stall detection 304 305 2. **Deployment Automation** 306 - Create deployment script with compatibility checking 307 - Automate binary verification across different CPU architectures 308 - Implement rolling deployment with health checks 309 310 3. **Monitoring & Alerting** 311 - Deploy Prometheus metrics collection 312 - Set up Grafana dashboards for validator health 313 - Configure alerts for sync failures, consensus drops 314 315 --- 316 317 ## Conclusion 318 319 The testnet deployment was partially successful. The updated AlphaOS binaries were successfully deployed to all 5 validators, and 4 out of 5 are producing blocks in consensus. However: 320 321 **Successes**: 322 - ✅ Binary deployment pipeline works correctly 323 - ✅ CPU architecture compatibility issue resolved 324 - ✅ 4/5 validators operating in healthy consensus 325 - ✅ BFT consensus mechanism functioning correctly 326 327 **Limitations**: 328 - ⚠️ Automatic genesis fetch could not be tested in dev mode 329 - ⚠️ testnet001 experiencing critical sync issues 330 - ⚠️ Genesis caching and BFT verification untested 331 332 **Critical Issue**: 333 - ❌ testnet001 sync failure requires immediate investigation 334 335 **Test Scenario 2 Status**: INCOMPLETE - Genesis fetch testing blocked by dev mode behavior. Recommend retesting in production mode configuration. 336 337 --- 338 339 ## Appendix: Configuration Details 340 341 **Validator Configuration** (testnet001): 342 ``` 343 Network: 1 (testnet) 344 Dev Mode: 0 (first validator in 5-node devnet) 345 Dev Validators: 5 346 Node Port: 4130 347 BFT Port: 5000 348 REST Port: 3030 349 Peers: 178.156.159.24:4130,46.62.225.199:4130,65.21.149.67:4130,157.180.28.93:4130 350 Validators: 178.156.159.24:5000,46.62.225.199:5000,65.21.149.67:5000,157.180.28.93:5000 351 ``` 352 353 **Server Specifications** (all validators): 354 - CPU: 8 cores (AMD EPYC) 355 - RAM: 30 GiB 356 - OS: Ubuntu (Linux 6.8.0) 357 - SSH Port: 2584 358 - Firewall: UFW (configured for AlphaOS ports) 359 360 **Network Topology**: 361 ``` 362 testnet001 (65.108.155.133) - STUCK 363 testnet002 (178.156.159.24) - HEALTHY 364 testnet003 (46.62.225.199) - HEALTHY 365 testnet004 (65.21.149.67) - HEALTHY 366 testnet005 (157.180.28.93) - HEALTHY 367 ``` 368 369 --- 370 371 **Report Generated**: 2026-01-21 18:25 UTC 372 **Test Duration**: ~35 minutes 373 **AlphaOS Commit**: Latest main branch (rebuilt with x86-64 compatibility)
