Exploring the Block Details

A block is a core concept that can be thought of as a page in a ledger. A block contains transaction data and the hash of the previous block that ensures immutability and security in the blockchain network.

Navigating a Block Details Page

  1. Labels: Added to relevant blocks, labels provide additional information regarding them.
  2. Block Height: The block height, also known as block number, which indicates the position of a particular block in the blockchain.
  3. Age: How long ago a block was mined. Can be toggled with Date Time (UTC) to display the date and time at which the block is mined.
  4. Transactions: The number of transactions in the block. Contract internal transactions refer to transactions that are created from contract executions and  transact Ether.
  5. Mined by: Miner who successfully mined the block.
  6. Block Reward: The total block reward received by the miner for including the block in the blockchain. The breakdown of rewards (static block reward, gross transaction fees, deduction of burnt fees, uncle inclusion rewards) are also displayed.
  7. Uncles Reward: Rewards given to a miner who mined an uncled block that was included in the viewed block. Read more about uncles here.
  8. Difficulty: The amount of work required to mine a new block. The difficulty adjusts based on total hash power mining on the blockchain.
  9. Total Difficulty: Total difficulty of mining the chain (measured in hashes) until this block.
  10. Size: Size of the block in bytes. It is determined by the block's gas limit.
  11. Gas Used: The total gas used in the block. The gas used percentage (out of total gas limit) as well as percentage of gas used over the gas target are also included.
  12. Gas Limit: Total gas limit for the block.
  13. Base Fee Per Gas: Post-London Upgrade, this represents the minimum gasUsed multiplier required for a tx to be included in a block.
  14. Burnt Fees: Post-London Upgrade, this represents the part of the tx fee that is burnt: baseFeePerGas * gasUsed. The burnt fees percentage out of total transaction fees is also displayed.
  15. Extra Data: Any data that can be included by the miner in the block.
  16. Hash: The hash of the block header of the current block.
  17. Parent Hash: The hash of the block from which this block was generated, also known as its parent block.
  18. Sha3Uncle: The mechanism with which Ethereum Javascript RLP encodes an empty string.
  19. StateRoot: The root of the state trie.
  20. Nonce: Block nonce is a value used during mining to demonstrate proof of work for a block.
