TRON Streams

You can find the schema here.

TRON produces blocks approximately every 3 seconds, offering high throughput for transactions and smart contracts.

Structure of On-Chain Data​

The TRON Protobuf Streams provide three main message types for different use cases:

  • BlockMessage: Full blocks with detailed transaction information
  • TokenBlockMessage: Focused on token transfers
  • DexBlockMessage: Specialized for DEX (Decentralized Exchange) trading activity

Block-Level Data​

Each block in the stream includes a BlockHeader with fields such as:

  • Number: Block height in the chain
  • Hash: The unique identifier of the block
  • Timestamp: When the block was produced
  • ParentHash: Hash of the previous block
  • TxTrieRoot: Merkle root of transactions
  • AccountStateRoot: State root hash
  • TransactionsCount: Number of transactions in this block

The BlockMessage also includes:

  • Chain: Information about the blockchain
  • Witness: Details about the block producer (Super Representative)
    • Address: The witness account address
    • Id: Witness identifier
    • Signature: Block signature

Transaction-Level Data​

Transactions include:

  • TransactionHeader: Core transaction data

    • Hash: Transaction hash
    • Fee: Transaction fee
    • Index: Position in the block
    • Expiration: When the transaction expires
    • FeeLimit: Maximum fee allowed
    • Signatures: Transaction signatures
    • FeePayer: Account that pays the fee

  • Result: Execution outcome

    • Status: Transaction status
    • Success: Whether transaction succeeded
    • Message: Error message if failed

  • Receipt: Resource consumption details

    • EnergyUsageTotal: Total energy consumed
    • EnergyFee: Fee paid for energy
    • NetUsage: Bandwidth used
    • NetFee: Fee paid for bandwidth

Contract Data​

The Contract section contains detailed information about smart contract interactions:

  • Address: Contract address

  • Type: Contract type (e.g., "TransferContract", "TriggerSmartContract")

  • TypeUrl: Protocol buffer type URL

  • Arguments: Contract-specific arguments

  • InternalTransactions: Sub-transactions created during execution

    • CallerAddress: Initiator address
    • TransferToAddress: Recipient address
    • CallValues: Assets transferred
    • Note: Additional information

  • Logs: Event logs emitted by the contract

  • Trace: Detailed execution trace (similar to EVM)

  • RewardWithdraw: Information about reward distribution

Token Data​

The TokenBlockMessage stream provides information about token transfers:

  • TokenTransfer: Records token movements with:
    • Sender: Address sending tokens
    • Receiver: Address receiving tokens
    • Amount: Amount of tokens transferred
    • Currency: Detailed token information
    • Success: Whether the transfer succeeded

TRON supports multiple token standards:

  • TRC10: Native TRON tokens identified by TokenId
  • TRC20: Similar to ERC20 on Ethereum
  • TRC721/TRC1155: Non-fungible tokens

DEX (Decentralized Exchange) Data​

The DexBlockMessage stream is specialized for DEX trading activity:

  • DexTrade: Records of trades executed on DEXs
    • Buy/Sell: Both sides of the trade
    • Dex: Information about the exchange
    • Success: Whether the trade succeeded
    • Fees: Trading fees paid

TRON-Specific Features​

TRON has several unique features compared to other blockchain protocols:

  • Energy and Bandwidth Model: Instead of a simple gas model, TRON uses Energy for smart contract execution and Bandwidth (Net) for transaction size
  • Witness System: Block producers are called Witnesses or Super Representatives
  • Contract Types: TRON has predefined contract types for common operations
  • TRC10 Tokens: Native token support without smart contracts, referenced by TokenId
  • Resource Delegation: Users can delegate resources to each other

Using This Stream in Python, JavaScript, and Go​

Python, JavaScript, and Go code samples can be used with these streams by changing the topic to one of:

  • tron.raw.proto (for raw block data)
  • tron.transactions.proto
  • tron.tokens.proto
  • tron.dextrades.proto
  • tron.broadcasted.raw.proto (for raw broadcasted block data)
  • tron.broadcasted.transactions.proto (for broadcasted transactions)
  • tron.broadcasted.tokens.proto (for broadcasted token transfers)
  • tron.broadcasted.dextrades.proto (for broadcasted DEX trades)

The Python package bitquery-pb2-kafka-package includes all schema and is up to date so you don't have to manually install schema files.
