What is a Blockchain Token? We have answers

People are just becoming acquainted with the idea of digital money in the form of cryptocurrencies like bitcoin, where transactions are recorded on a secure distributed database called a blockchain. And now along comes a new concept: the blockchain-based token, which I’ve been following as a blockchain researcher and teacher of courses about cryptocurrency and blockchain tokens.In the last 18 months, digital developers have raised more than US$20 billion through a funding process called “initial coin offering” – many of which use tokens. There are two common categories of them: “utility” tokens and “security” tokens.Utility tokensUtility tokens are essentially cryptocurrencies that are used for a specific purpose, like buying a particular good or service. For example, if you want to store information online, the most common way today is to become a customer of a hosting service like Google Drive, Dropbox or Amazon Web Services. You reserve a certain amount of storage space on those companies’ servers and pay for it with dollars, euros, yen or other national currencies.Security tokensA security token, sometimes called a “tokenized security” or a “crypto-security,” is more than a currency – it often represents ownership in an underlying real-world asset. Like traditional stocks or bonds, they’re regulated by the U.S. Securities and Exchange Commission. Regular securities are tracked either on paper or – more likely these days – in a centralized database. Security tokens use a blockchain system – a decentralized database – to do the tracking of who owns which assets.
