The future is coming
Now we come to the critical part, and that is the blockchain, which is a decentralised system, meaning no one controls it, yee-hah! The blockchain uses digital recorded transactions across many, many computers, so this cannot be tracked, altered, hacked or stolen without knowing the calculations of over a million different combinations within 5 seconds of each block. And the best part, the blockchain is not controlled by any authoritative figures such as banks and governments.
Think of the possibilities in how we can use the blockchain? You bought a costly item, and you will have the digital records stored on the blockchain that the article belongs to you and will only work with your private data. If the item is lost or stolen, it will be useless without you transferring the records over.
