Blockchain is a decentralized digital ledger technology that records transactions across multiple computers in a way that ensures the security, transparency, and immutability of the data. Here are some detailed insights into blockchain technology: Decentralization:Unlike traditional centralized databases managed by a single entity, blockchain is maintained by a network of computers (nodes). Each node has a copy of the entire blockchain, ensuring that no single point of failure or control exists. Transparency and Immutability:Once data is added to the blockchain, it cannot be altered or deleted. This immutability provides a high level of security and trust. All transactions are visible to all participants in the network, promoting transparency. Security:Blockchain employs cryptographic techniques to secure data. Each block contains a unique hash and the hash of the previous block, forming a chain. Any attempt to alter a block would change its hash and break the chain, making tampering
