If I send you bitcoin, that transaction is simultaneously recorded on the more than 12,000 computers, servers, and other devices that Bitcoin runs on. Everyone on the chain can see the transaction, and no one can alter or delete it. Or you can send me a non-fungible token (NFT) on the Ethereum blockchain, and that transaction is simultaneously recorded across all the computers (also known as “nodes”) that Ethereum runs on. These two examples explain, roughly, what blockchain technology is: a way to keep unalterable records of transactions on multiple computers such that a new transaction cannot be recorded on one computer without simultaneously recording it on all the others. The applications of blockchain have grown well beyond cryptocurrency and NFTs, as governments and industries from health care to agriculture to supply-chain operations leverage the technology to improve efficiency, security, and trust.
