Blockchain, sometimes referred to as Distributed Ledger Technology (DLT), makes the history of any digital asset unalterable and transparent through the use of decentralization and cryptographic hashing. Blockchain is an especially promising and revolutionary technology because it helps reduce risk, stamps out fraud and brings transparency in a scalable way for myriad uses.
Cryptocurrencies are digital currencies (or tokens), like Bitcoin, Ethereum or Litecoin, that can be used to buy goods and services. Just like a digital form of cash, crypto can be used to buy everything from your lunch to your next home. Unlike cash, crypto uses blockchain to act as both a public ledger and an enhanced cryptographic security system, so online transactions are always recorded and secured.
Tokens can be music files, contracts, concert tickets or even a patient's medical records. Most recently, Non-Fungible Tokens (NFTs) have become all the rage. NFTs are unique blockchain-based tokens that store digital media (like a video, music or art). Each NFT has the ability to verify authenticity, past history and sole ownership of the piece of digital media. NFTs have become wildly popular because they offer a new wave of digital creators the ability to buy and sell their creations, while getting proper credit and a fair share of profits.
