Streaming real-time txns

Macha's highly efficient system fetches real-time events with near 0% latency. This function listens to events triggered from the current timestamp of running the node.

A stream is initiated which periodically checks for new events. For every valid event caught, the loop is run to decode the associated data. This data arrives RawData which cannot be utilized directly. Hence, it must be deciphered and simplified to a usable form. The decoded data consists of - method params, function name, transaction hash and the transaction receipt.

To get the data of all previous transactions, head to the next section.

Fetching historical txns

In this section, we go over how historical transactions are fetched. Crate ethers is used to create a client and fetch all previous transactions. The results can be restricted by start_block and end_block as the lower bound and upper bound respectively.

Once this data is received successfully, it is formatted and added to the database as shown above.
