## Sample Notice |
|
|
|
|
|
This dataset contains **a small sample** of the full BlockDB Raw Blocks dataset. |
|
|
It is provided **for evaluation, research, and interoperability testing only**. |
|
|
|
|
|
If you need full historical coverage, real-time streaming, or end-of-day (EOD) exports |
|
|
please contact us directly: |

|
## Dataset Overview |
|
|
Each block entry contains the complete structural and integrity metadata required to reconstruct or verify the block state: |
|
|
hashes, parent linkage, miner address, gas and size metrics, timestamps, extra data, and lineage identifiers (_tracing_id, _computed_receipt_root). |
|
|
|
|
|
|
|
|
## Chains and Coverage |
|
|
ETH, BSC, Base, Arbitrum, Unichain, Avalanche, Polygon, Celo, Linea, Optimism (others on request). |
|
|
Full history from chain genesis; reorg-aware real-time ingestion and updates. |
|
|
|
|
|
|
|
|
## Schema |
|
|
List of columns exactly as delivered: |
|
|
|
|
|
• block_number BIGINT - Sequential block number |
|
|
• block_hash BYTEA - 32-byte block hash |
|
|
• parent_hash BYTEA - 32-byte parent block hash |
|
|
• receipts_root BYTEA - Root hash of all receipts in the block |
|
|
• miner BYTEA - 20-byte miner (beneficiary) address |
|
|
• gas_limit NUMERIC(78,0) - Maximum gas allowed for the block |
|
|
• extra_data BYTEA - Arbitrary ≤32-byte payload embedded by the block producer |
|
|
• size BIGINT - Total block size in bytes (header + transactions + receipts) |
|
|
• timestamp_utc TIMESTAMPTZ - UTC timestamp when the block was mined |
|
|
• _tracing_id BYTEA - Deterministic tracing ID of this block record |
|
|
• _computed_receipt_root BYTEA - Recomputed receipts root (BlockDB integrity check) |
|
|
• _computed_receipt_timestamp_utc TIMESTAMPTZ - Timestamp when the receipts root was computed or revalidated |
|
|
• _created_at TIMESTAMPTZ - Record creation timestamp |
|
|
• _updated_at TIMESTAMPTZ - Record last update timestamp |
|
|
|
|
|
|
|
|
### Notes |
|
|
• Use encode(block_hash, 'hex') to convert binary values to hex for presentation or joins. |
|
|
• Every block record is verified against the node RPC. |
|
|
|
|
|
|
|
|
## Lineage |
|
|
Each block record includes a deterministic _tracing_id, forming the root lineage reference for all derived BlockDB datasets (swaps, liquidity, and token prices). |
|
|
This ensures verifiable traceability, reproducibility, and proof-of-derivation for every downstream record. |
|
|
|
|
|
|
|
|
## Common Use Cases |
|
|
• Benchmarking node or indexer consistency across chains |
|
|
• Establishing canonical ground truth for analytics or compliance systems |
|
|
• Foundation layer for derived token, swap, and liquidity datasets |
|
|
• Validating receipts and state integrity with recomputed roots |
|
|
|
|
|
|
|
|
## Quality |
|
|
• Verifiable lineage: deterministic cryptographic hashes per row |
|
|
• Reorg-aware ingestion: continuity and consistency across forks |
|
|
• Complete historical coverage: from chain genesis to present |
