Blockchain is a decentralized digital ledger technology that records transactions across a network of computers. This system ensures that once a transaction is entered, it becomes immutable and transparent, preventing any unauthorized alterations. Each block in the blockchain contains a list of transactions and is linked to the previous block, forming a chain. This structure ensures security and trust without the need for central authority. Blockchain is widely used in cryptocurrencies like Bitcoin, but its applications extend to various industries, including supply chain management, finance, and healthcare, offering enhanced transparency, traceability, and efficiency.
Examples of blockchains Stellar, Bitcoin, Ethereum, Binance Smart Chain, Cardano, Solana, Polkadot, Ripple, Litecoin, Chainlink, Tezos, Avalanche, Polygon, Tron, and EOS are some of the prominent blockchains shaping the digital landscape. Each of these blockchains offers unique features and functionalities, contributing to the diverse ecosystem of decentralized technologies.
