Defining Blockchain
At its core, blockchain is a distributed ledger technology. Imagine a digital ledger, similar to a spreadsheet, that records transactions across a network of computers. Each participant in the network has a copy of this ledger, which is constantly updated and synchronized. Every time a new transaction occurs, a record of that transaction is added to each participant’s ledger, creating an immutable and transparent history.
Key Characteristics of Blockchain
Decentralization: Blockchain networks are not controlled by a single entity. Instead, they are distributed across multiple computers, or “nodes,” ensuring no central authority can manipulate the system. Transparency: All transactions on the blockchain are visible to all participants, providing an unprecedented level of transparency. This makes it difficult to alter or manipulate data without the network’s knowledge. Immutability: Once a transaction is recorded on the blockchain, it cannot be altered or deleted. This immutability ensures the integrity of the ledger and builds trust among users. Security: Blockchain networks employ cryptography to secure transactions and protect data. Each transaction is encrypted, and the decentralized nature of the network makes it highly secure, as there is no single point of failure.
Blockchain’s Impact on Industries: Transforming Traditional Processes
