Book or record keeping methods, such as using a ledger, become increasingly complicated due to the increasing number of participants and the complexity of transactions. The traditional way of maintaining a ledger is for it to be centralized. This approach lacks transparency, leading to frequent disputes legally or not legally. It is also difficult to identify an error as parties involved in a transaction do not have an efficient real-time method to check and verify transaction facts against the ledger.  Blockchain technology can resolve the issues seamlessly. The decentralized and immutable ledger maintained on the chain virtually eliminates any chance of a dispute and brings trust between parties in transactions.  Blockchain allows for real-time queries and permits parties to ensure their correctness. Unlike the traditional way, where two trading parties kept entries in their respective ledgers, possibly leading to discrepancies, the blockchain ledger allows all parties to maintain a unified ledger, eliminating the possibility of inconsistencies.
