Parameters

  1. block hash (string, required): The hash of the block to retrieve details for

​
Response

The method returns an enhanced block object with additional calculated fields.

​

    • number — the block number
    • hash — the block hash
    • parentHash — the parent block hash
    • timestamp — Unix timestamp of the block
    • gasLimit — maximum gas allowed in the block
    • gasUsed — total gas used by all transactions
    • miner — address that mined/validated the block
    • baseFeePerGas — base fee per gas (post-EIP-1559)
    • transactions — array of transaction objects
    • transactionCount — number of transactions in the block
  • issuance — block reward issuance information
    • blockReward — reward for mining the block
    • uncleReward — rewards for uncle blocks

Use cases

The ots_getBlockDetailsByHash method is essential for:
  • Block explorers: Display comprehensive block information when accessed by hash
  • Block verification: Retrieve detailed information for specific known blocks
  • Cross-reference validation: Verify block data using hash identifiers
  • Fee reconciliation: Calculate total fees for specific blocks
  • Fork detection: Analyze blocks on different chain branches
  • Archive queries: Access historical block data by hash
  • Integration testing: Verify specific blocks in test scenarios
  • Audit trails: Reference specific blocks in compliance reports
  • Performance benchmarking: Analyze specific blocks for metrics
  • Research tools: Study particular blocks of interest
This method is particularly useful when you have a block hash from an event log or transaction receipt and need to retrieve comprehensive block information.
