Blockchain is a method of tracking transactions using a public, globally-distributed ledger. It is most commonly used for cryptocurrency, such as Bitcoin. Blockchain automatically and securely keeps a historical record, or ledger, of all transactions; working across a network of computers, cryptocurrencies can operate without a central authority. It is already revolutionizing online gambling and is now emerging in video games. For example, an emerging trend in gaming culture is the integration of cryptocurrency and non-fungible tokens (NFTs). NFTs allow blockchain to issue one-of-a-kind digital assets with unique attributes, meaning that players can acquire securely stored in-game assets. (Source: IntentaDigital http://bitly.ws/sLEU)
