1. Multi-Source RPC Ingestion
Multiple independent endpoints. Lagging nodes auto-excluded based on block-height thresholds. Cross-validation catches silent inconsistencies single-source pipelines miss.
2. Transaction Root Reconstruction
Trie root recomputed from ingested transactions and verified against the block header. One missing tx = root mismatch. Cryptographic proof of completeness.
3. Log Bloom Verification
2048-bit Bloom filter recomputed from ingested logs and checked against the block header. Catches missing events, wrong topics, and truncated receipts.
4. Log Index Continuity
Log indexes validated as continuous per block. A gap = definitive proof of missing events. Deterministic complement to probabilistic Bloom verification.
5. Failed Tx Preservation
status: 0 as a first-class field. Full receipt data, gas consumption, all logs. Most providers silently drop failed txs — breaking MEV analysis, gas modeling, and security monitoring.
6. Immutable Parquet
Validated data written to compressed, immutable Parquet files with Bloom indexes. Never modified after write. Same query = same result, forever. The file is the proof.
