What is Blockchain?
Blockchain technology is a digital ledger that allows data to be stored globally on thousands of servers. It lets participants in the network verify and audit transactions independently and relatively inexpensively. A key feature of blockchain is that it ensures the fidelity and security of a record of data without the need for a trusted third party.
How Does Blockchain Work?
At its core, blockchain is a distributed database that maintains a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a cryptographic hash of the previous block, a timestamp, and transaction data. By design, blockchains are inherently resistant to modification of the data.
Benefits of Blockchain
Blockchain technology offers numerous benefits, including:
- Transparency: All network participants share the same documentation as opposed to individual copies.
- Security: Once a transaction is recorded, it cannot be altered without altering all subsequent blocks.
- Efficiency: Blockchain can streamline and automate processes that are traditionally time-consuming and prone to human error.
Blockchain and Cryptocurrency
Blockchain is the backbone of cryptocurrencies like Bitcoin and Ethereum. It provides a secure and decentralized way of recording transactions, which is essential for the functioning of any digital currency. For more on how blockchain powers cryptocurrencies, check out our guide to cryptocurrency.
