+*Small evaluation sample.*
 
-## Sample Notice
+**`0122`** · `blockdb_evm.b0122_function_results_v1` - On-chain function call return values versioned by block. Uses `contract_id` (26 bytes) to support metamorphic contracts; primary key is `(contract_id, block_number, call_data)`.
 
-This dataset contains **a small sample** of the full BlockDB Raw Function Results dataset.  
-It is provided **for evaluation, research, and interoperability testing only**.

-## Dataset Overview
-On-chain contract function call return values versioned by block. Each row records the raw output of a deterministic view function call at a specific block height, enabling time-travel queries over any contract's on-chain state. Uses a 26-byte contract_id (consistent with the contracts dataset) to correctly handle metamorphic contracts.

-
-## 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:
-
-	•	contract_id BYTEA – Part of PK; 20 bytes (address) + 4 bytes (creation block BE) + 2 bytes (tx_index BE); links to b0121_contracts_v1
-	•	block_number BIGINT – Part of PK; block at which the value was read
-	•	block_time TIMESTAMPTZ – UTC timestamp when the block was mined
-	•	call_data BYTEA – Part of PK; raw call data used to invoke the function
-	•	signature_hash BYTEA – 4-byte selector (keccak256(signature)[0..3])
-	•	result BYTEA – Raw return data from the function call (null if reverted)
-	•	timestamp_utc TIMESTAMPTZ – UTC timestamp when the function call result was recorded
-	•	_tracing_id BYTEA – Deterministic tracing ID of this function result record
-	•	_created_at TIMESTAMPTZ – Record creation timestamp
-	•	_updated_at TIMESTAMPTZ – Record last update timestamp
-
-
-### Notes
-	•	Primary key: (contract_id, block_number, call_data) enables point-in-time lookups per contract per call.
-	•	result is raw ABI-encoded bytes; decode using the ABI for the matching signature_hash.
-	•	NULL result indicates a reverted call at that block.
-	•	Use encode(contract_id, 'hex') to convert binary values to hex.
-
-
-## Lineage
-Each function result record includes a deterministic _tracing_id, providing:
-
-	•	Provenance tracking from raw RPC calls to versioned contract state snapshots
-	•	Reproducible analytics and signal extraction
-	•	Cross-system consistency checks (RPC vs. indexers vs. internal warehouses)
-
-
-## Common Use Cases
-	•	Historical state reconstruction and time-travel queries
-	•	Token metadata and balance lookups at specific blocks
-	•	Contract configuration and parameter tracking over time
-	•	Price oracle and external data feed analysis
-	•	Governance proposal and voting state tracking
-
-
-## Quality
-	•	Verifiable lineage: deterministic cryptographic hashes per row
-	•	Reorg-aware ingestion: continuity and consistency across forks
-	•	Complete historical coverage: from chain genesis to present
