Demystifying Blockchain Technology: How It Works Under the Hood
Demystifying Blockchain Technology: How It Works Under the Hood Introduction Blockchain technology has become synonymous with cryptocurrencies like Bitcoin, but its potential reaches far beyond digital money. Understanding how blockchain works under the hood reveals why it’s considered a revolutionary technology for secure, decentralized data management. What is Blockchain? A blockchain is a distributed ledger that records transactions in a secure, immutable way. It consists of a chain of blocks, each containing a batch of transactions. The ledger is maintained across a network of computers (nodes), making it decentralized. Core Components Blocks: Each block holds transaction data, a timestamp, and a cryptographic hash of the previous block. Hash: A unique identifier created by a cryptographic function. It links blocks together and ensures data integrity. Nodes: Computers in the network that maintain copies of the blockchain and validate transactions. Consensu...
