Blockchain technology is a decentralized, distributed, digital ledger system that records and stores data in a secure, immutable, and permanent way. It is used to track, store, and manage digital assets and transactions.
An example of blockchain technology is Bitcoin. Bitcoin is a digital currency system that uses blockchain technology to track and store transactions. It is secure, transparent, and decentralized, meaning that no single entity controls it. Each transaction is recorded on a public ledger, and users can verify the accuracy of the transaction with the help of cryptographic algorithms.
