— the most recent block in the blockchain and the current state of the blockchain at the most recent blockearliest
— the earliest available or genesis blockpending

eth_getBlockTransactionCountByNumber
code examples
Use case
eth_getBlockTransactionCountByNumber
can be used to analyze how many transactions are included on the Arbitrum blockchain in a certain period. On average, a new block is generated on the Arbitrum mainnet every 0.3 seconds, resulting in approximately 12,000 blocks per hour. Using the ethers.js library, one can inspect the past 12,000 blocks starting from the latest block, retrieve the hash of each block, and use eth_getBlockTransactionCountByNumber
to find the number of transactions in each block to sum them.
index.js
eth_getBlockTransactionCountByNumber
is a bit more straightforward compared to the example shown using eth_getBlockTransactionCountByHash
for this same use case, you don’t need to extract the block hash; instead, you can query the transaction count directly.
This example is made using the ethers.js library, and you can notice that it requires more parsing compared to web3.js, and the results are given as hexadecimal.Body
