Overview
BlockchainBlockData is a powerful function in the Wolfram Language that provides detailed information about Bitcoin blockchain blocks. Whether you're a developer, researcher, or cryptocurrency enthusiast, understanding this functionality can help you analyze blockchain data more effectively.
Key Features and Properties
Core Properties of Bitcoin Blocks
When using BlockchainBlockData, you can access these fundamental properties:
- BlockHash: The unique cryptographic hash identifying the block
- BlockNumber: The position (height) of the block in the blockchain
- Timestamp: When the block was mined
- ByteCount: Size of the block in bytes
- Nonce: The random number used in the block's hash
- Version: Block protocol version
- Confirmations: Number of subsequent blocks confirming this block
- PreviousBlockHash: Reference to the preceding block
- MerkleRoot: The root hash of all transactions in the block
- TotalTransactions: Count of transactions included
- TransactionList: IDs of all transactions in the block
Financial Attributes ("Amounts")
The "Amounts" property returns an association with these financial metrics:
| Metric | Description |
|---|---|
| BlockReward | Mining reward for creating the block |
| TotalFee | Sum of all transaction fees in the block |
| TotalInput | Combined value of all transaction inputs |
| TotalOutput | Combined value of all transaction outputs |
Configuration Options
The function supports these configuration options:
BlockchainBase: Specifies which network to query
- Default: "Bitcoin" (mainnet)
- Alternative: "BitcoinTestnet" for testing network
MaxItems: Controls how many items to return
- Default: All available items
- Can specify numerical limits

Practical Examples
Basic Usage
Retrieve block by height:
BlockchainBlockData[500000]Get latest testnet block:
BlockchainBlockData[-1, BlockchainBase -> "BitcoinTestnet"]Query by block hash:
BlockchainBlockData["0000000000000000001234567890abcdef..."]
Advanced Applications
Calculate block size in MB:
BlockchainBlockData[-1]["ByteCount"]/10^6Extract miner information:
coinbase = First[BlockchainBlockData[-1]["TransactionList"]]; BlockchainTransactionData[coinbase]["InputScript"]
Common Issues and Solutions
- Nonexistent Hash: Returns $Failed if the hash doesn't exist
- Invalid Hash Format: Ensure proper 64-character hexadecimal format
FAQ Section
How do I access testnet vs. mainnet?
Use the BlockchainBase option with "Bitcoin" for mainnet or "BitcoinTestnet" for testnet.
What's the difference between BlockNumber and Confirmations?
BlockNumber is the position in the chain, while Confirmations counts how many blocks follow it.
Can I get transaction details from a block?
Yes, use the TransactionList property with BlockchainTransactionData.
