Hi everyone, I am new to etherscan and crypto in general. My question is I want to process the list of transactions on a wallet and send pings to my client, I have read at multiple places that I can use startblock and endblock to specify volume of transactions I want, still its not fully clear to me. What I want is all transactions after a specific blocknumber for a specific wallet, any help would be greatly appreciated. TL;DR: What exactly are blockNumber, start_block and end_block
