Blockchain is a decentralized database consisting of a chain of blocks that store information about cryptocurrency transactions. Its unique structure ensures transparency and security in the system.

Decentralization: Data is stored on multiple computers, eliminating a single point of failure.
Transparency: Every transaction is recorded in the ledger and accessible to network participants.

Immutability: Records cannot be altered or deleted, enhancing trust in the system.
