For today’s Monday Minutes, Tom discusses his recent work with blockchain and NFTs, or non-fungible tokens. Blockchain is a specific type of database in which information is stored in chains, as opposed to tables in an Excel spreadsheet. He gives a simplified explanation of how data is stored and encrypted in a blockchain. Bitcoin is the most known type of data stored in a blockchain. Tom touches on why some people prefer bitcoin over traditional banking and how blockchains protect the data stored inside them.
