A blockchain is a list of growing records called blocks, blocks are tied up or linked together by cryptography. You could imagine this, blocks represent several different aspects of a data transition all tied up together securely by cryptography. A blockchain holds valid transactions, hashed and coded into a Merkle tree. A Merkle tree is a summary of all the transactions in a block. In addition to that, blockchain will fundamentally change the business model that affects gaming. It will lean more towards the players and players’ freedom.
