What is Blockchain? Blockchain is a digital ledger technology that allows multiple parties to maintain a shared database of transactions and other data in a secure and transparent manner. In a blockchain, data is stored in blocks that are connected to each other in a chronological and decentralized manner. Each block contains a set of transactions, a timestamp, and a unique cryptographic code called a hash. Once a block is added to the chain, it cannot be altered or deleted without consensus from the network. This makes blockchain a secure and tamper-proof way to store data, making it useful for a variety of applications such as cryptocurrency transactions, supply chain management, and voting systems. Blockchains can be public or private, with different levels of access and permission requirements for participants. Advantages of Blockchain Technology : Security: Blockchain technology is highly secure and tamper-proof, as data is stored in a decentralized network and each bl...
