After reading about IPFS and do few examples about it. I'm thinking of few questions, if anyone read my post and know answer, plz explain me, you're doing good thing
1. When I upload my file to IPFS, it will be stored somewhere in some nodes. But if I want to download my file, at least one of those nodes has to be online right?
2. When a file upload to IPFS, supposed it uploaded to IPFS and then IPFS delivers it to my computer (whole file or few blocks of it), so this process is automatically? Even when I don't give it permission?
3. Is the process of delivery file into IPFS network automatic, can I affect it to deliver to some of specific nodes?
Thank you for reading and answering my questions!
