<human>:  Explain blockchain technology.
<bot>: Blockchain technology is an immutable, distributed digital ledger that records transactions publicly and chronologically. It is a peer-to-peer network of computers working together to validate and store transaction records across a decentralized network. Data stored on the blockchain is distributed and secure, meaning it can be accessed by multiple parties, with each instance having the same records. Transactions are verified through cryptography, and each block in the chain is linked to the previous one with a unique identifier or “hash”. This technology is revolutionary for its trustless approach to transactions and ownership, and it has been used to create many new opportunities in the global market.
