Blockchain is the backbone of most cryptocurrencies. It's a distributed database that stores information about all transactions in the network. The main advantage of blockchain is its security and transparency. Each block contains data about the previous block, making it nearly impossible to tamper with information. Additionally, every participant in the network has access to all the information, making the system open and transparent.
