I am a beginner to Dapps on ethereum and smart contracts but I wanted to ask three questions on building on top of ethereum.
Firstly, how fast would an Dapp with a token will the transactions per second and the time of a smart contract to be executed the same as the ethereum blockchain.
Secondly, I hear ethereum uses IPFS, like AWS S3, for storage but what will cost to storage data and how fast will can it be uploaded and downloaded, if it was 1 Mb?
Lastly, do need to download the whole ethereum blockchain to be able use a Dapp built on top of ethereum?
I know, there alot of questions but I am just curious and Thank you, in advance, for answering my questions.
