eth_getBlockByNumber
method is crucial here as it allows the script to fetch the entire block data, including the full list of transactions within each block. By doing so, the script can then iterate through these transactions to identify those that involve the specified address. This method provides a way to access historical data on the blockchain, making it a valuable tool for auditing and monitoring activities.
In a new file, paste the following code:
get_transactions_for_address
function, a meticulously designed piece of logic that scans the blockchain to identify transactions involving a specific address within a user-defined range of blocks. Here’s an overview of its operation:
from_block
to the ending block number in to_block
.from
) and recipient (to
) addresses. The transaction hash is captured and stored in a list if it identifies a transaction where the specified Ethereum address is either the sender or the recipient.from_block
and to_block
parameters. These values define the scope of your transaction search, and their optimal setting depends on your specific use case. Whether you’re interested in a brief snapshot of recent activity or an exhaustive historical audit, adjusting these parameters allows you to focus your query accordingly.
get_block
method can be resource-intensive—especially when dealing with a large range of blocks. One effective strategy for speeding up the data retrieval process is through parallelization. By employing multi-threading, you can distribute the workload across multiple threads, reducing overall runtime. The script includes a parallelized version of the core function, demonstrating how multi-threading can significantly improve performance.
