Blockchain

Blockchain is a distributed ledger technology that securely records transactions across multiple computers in such a way that the registered data cannot be altered retroactively without the consensus of the network. It consists of a chain of blocks, each containing a list of transactions, and is maintained by a network of nodes that validate and confirm these transactions. The decentralized nature of blockchain ensures transparency and reduces the risk of fraud, as every participant in the network has access to the same information. Blockchain is the foundational technology behind cryptocurrencies like Bitcoin but has applications across various industries, including finance, supply chain, healthcare, and beyond, where secure and verifiable record-keeping is essential.
