How Blockchain Works
Blockchain stores transaction data in blocks and connects these blocks in a chain. Each block contains the hash of the previous block, ensuring data integrity. The core of blockchain is its decentralized ledger technology, which allows all participants to share the same data, enhancing trust. Consensus algorithms like Proof of Work and Proof of Stake play a crucial role in maintaining the network's security.

Advantages of Blockchain
One of the most significant advantages of blockchain is its transparency. All transactions are recorded on the blockchain, allowing anyone to access this information and build trust. Additionally, blockchain offers security against hacking attacks due to its robust structure. Each block includes the hash of the previous one, maintaining the integrity of the data. Finally, blockchain provides the benefits of decentralization. It can operate without a central authority, creating a transparent system that is not subject to control by any single entity. These characteristics establish blockchain as a foundation for innovative changes across various industries.
