in that case, some businesses don't really need blockchain, but for financial reasons, the existence of blockchain is needed by everyone
because the other function of blockchain is to make all transactions that occur, safer, cheaper and faster. Everyone must be able to use blockchain in the right interests, not in advertising systems, blogging and so on, where there are already centralized parties that are already perfect, although there must also be those that require transparency and require using blockchain
Yeah we need blockchain technology because I heard that with the use of blockchain technology thins will be more easy and we will feel comfort while using Blockchain in the future. Time is near that people will use blockchain technology. Understanding this technology is not easy because one of my friends is doing his Ph.D. degree in blockchain technology.
