Blockchain

Blockchain is a decentralized digital ledger technology that records transactions across multiple computers in a way that the registered information cannot be altered retroactively. Each data block contains a list of transactions and is linked to the previous block, forming a chain. This structure ensures transparency, security, and immutability, as altering any single block requires the consensus of the entire network. Blockchain technology is most commonly associated with cryptocurrencies like Bitcoin but has applications beyond that, including supply chain management, smart contracts, and secure record-keeping in various industries. In the context of human resources (HR), blockchain can be used for improving recruitment processes, securing employee records, and enhancing the verification of credentials.
