Blockchain projects are crypto currency at the same time?
For example, when I develop a project using the blockchain infrastructure, I develop a new crypto currency?
no. there are many blockchains intended to be developed on top of. that's why they exist. ethereum's getting all the hype right now because it's being trialled by companies looking to use blockchains for things.
go check an ethereum forum and the amount of projects will make your head spin.
as for whether there's a blockchain in real world use, the only truly widespread application is of course money such as bitcoin.
I would like to develop a blockchain project from scratch without using any infrastructure like ethereum. What is required for this?
I want to develop a blockchain-based project. When I develop a blockchain-based project from scratch, is this the crypto currency at the same time?
