What is Blockchain?
Blockchain technology is a digital ledger that records transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network. This makes blockchain a secure and transparent way to conduct transactions without the need for a central authority.
How Does Blockchain Work?
At its core, blockchain is a chain of blocks, where each block contains a list of transactions. Each block is connected to the one before and after it, creating a chain. This structure ensures that once a block is added to the chain, it cannot be changed without altering all subsequent blocks, which requires the consensus of the network majority.
Key Features of Blockchain
- Decentralization: Unlike traditional ledgers or databases controlled by a single entity, blockchain is distributed across multiple nodes, making it more secure and less prone to fraud.
- Transparency: All transactions on the blockchain are visible to all participants, ensuring transparency and trust among users.
- Immutability: Once a transaction is recorded on the blockchain, it cannot be altered or deleted, ensuring the integrity of the data.
Benefits of Blockchain Technology
Blockchain offers numerous benefits across various sectors, including finance, healthcare, and supply chain management. Some of the key benefits include reduced transaction costs, increased security, and improved traceability of transactions.
