What is the underlying technology behind Cryptocurrency?

The underlying technology behind cryptocurrency is blockchain, a secure, digital ledger system that records and verifies transactions. Blockchain technology provides a distributed, immutable, and secure way of transferring data across a peer-to-peer network, ensuring data security and integrity while eliminating the need for intermediaries. This secure system makes it possible to store and verify data in a highly efficient manner, which is why it is the technology powering many modern cryptocurrencies like Bitcoin.
