Could somebody please clarify something for me? The way I understand it, blockchain is a technology that entails many computers in a network maintaining a single ledger. All the computers all work together to make sure the ledger is the same on all computers. Is that about right? If that's right, then what is this article even talking about? I mean, blockchain is basically just a way to store and communicate information, isn't it? Automatically tracking supply chains could be done without blockchain.
Blockchains can use
oracles to record data onto the blockchain automatically. For example, blockchains can keep track of the temperature at which food products are stored and record the data onto the blockchain. And since blockchains are untamperable, they provide transparency.
