I am working on an ethereum project but I have some doubts. I have a backend that connects to the blockchain via web3.js. To connect to the blockchain I use a geth node. I understand that the sequence is this:

send transacrion enter image description here listen to events enter image description here my questions are:

  • What is the component sending the transaction? Is it the backend component or the geth node?
  • Then suppose that another smart contract in the network emits an event that I want to capture. What is the component that captures the event? Is it the backend component or the geth node?
