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 blockchain database is managed autonomously using a peer-to-peer network and a distributed timestamping server.
How Does Blockchain Work?
When a transaction is initiated, it is broadcasted to a peer-to-peer network of computers, known as nodes. These nodes validate the transaction using known algorithms. Once verified, the transaction is combined with others to create a new block of data for the ledger. The new block is then added to the existing blockchain, in a way that is permanent and unalterable.
Benefits of Blockchain Technology
Blockchain 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 reduce the time and cost associated with intermediaries and manual processes.
Blockchain and Cryptocurrency
Blockchain is the backbone of cryptocurrencies like Bitcoin and Ethereum. It provides a secure and decentralized way of recording transactions, making it ideal for digital currencies. For more on how blockchain powers cryptocurrencies, check out our guide to cryptocurrency.
