Blockchain technology is revolutionizing the digital world by offering a decentralized way to store and share information 🚀. At its core, a blockchain is a chain of blocks, where each block contains a list of transactions. These blocks are linked through cryptographic hashes, securing the data within.
Why Blockchain Matters?
Blockchains are designed to be immutable and transparent 🔓, making them ideal for applications requiring trust and accountability. Common use cases include cryptocurrencies like Bitcoin and Ethereum.
How Does Blockchain Work?
Traditional databases rely on a central authority for control, but blockchain uses a peer-to-peer network 👨💻👩💻 to validate and record data. Each participant (node) has a copy of the entire blockchain, ensuring trust through consensus mechanisms like Proof of Work or Proof of Stake.
