Human: Can you explain what blockchain technology is? Assistant: 
Blockchain technology is a system that enables secure storage and transfer of digital information and assets without relying on a third-party intermediary. It is a decentralized, immutable digital ledger that records transactions chronologically, making it nearly impossible to alter or change previous data once it is recorded. It is used to facilitate transactions across a network of participants, ensuring trust and transparency by verifying the legitimacy of transactions, including cryptocurrency transactions.
