block chain explorer Terminology

Block hash: refers to the hash value of this block, calculated based on the parent hash. When you want to view a certain block, you can query it through the block hash.

Block Height: Starting from the creation block, the fast height is recorded as 1. After each block is generated (different public chains, the number of blocks generated at a time may not necessarily be 1, such as Filecoin), increase by 1.

Transactions: Refers to the total number of transactions contained in the block, including both regular transactions and transactions that automatically execute smart contracts.

Block Reward: refers to the number of coins contained in this block.

Size: refers to the block size, not a fixed value, and is related to the number of transactions, but the maximum value for each block is 2M.

Transaction fee: The transaction fee in Ethereum, which is equal to the gas consumed multiplied by the price of gas. The transaction fee is related to the number of bytes occupied by the transaction and is not related to the size of the transfer amount.

Gas Limit: refers to the maximum amount of gas that can be used in this block. Only when the consumed gas is less than the gas limit (gas p="" limit), can the packaging be successful. Otherwise, it fails and starts from scratch<= ">

Difficulty: measures the average number of operations required to mine a block, reflecting how long it takes to mine a certain number of blocks at a certain level of difficulty. In addition, there is a total difficulty, which is the total mining difficulty of all blocks on the public chain.
