A blockchain ledger differs from a standard ledger in several ways: 1) It is decentralized, meaning there is no central authority controlling the data. Instead, multiple nodes on the network collectively maintain the ledger. 2) Transactions are recorded in blocks that are linked together through cryptographic hashes, creating an unalterable history of transactions. 3) Once a block is added to the chain, it cannot be modified or deleted without altering subsequent blocks, making it tamper-proof and resistant to fraud.
