The Latecomer’s Guide to Crypto (Published 2022)

You can think of a blockchain like a Google spreadsheet, except that instead of being hosted on Google’s servers, blockchains are maintained by a network of computers all over the world. These computers (sometimes called miners or validators) are responsible for storing their own copies of the database, adding and verifying new entries, and securin... See more

Bitcoin used a blockchain to keep track of transactions. That was notable because, for the first time, it allowed people to send and receive money over the internet without needing to involve a central authority, such as a bank or an app like PayPal or Venmo.
