Blockchain and banking ledgers are both systems for recording transactions, but they differ fundamentally in their structure, management, and transparency.

Blockchain is a decentralized, distributed ledger technology where transactions are recorded across multiple computers in a network. Each transaction is grouped into a block, which is then linked to the previous block, forming a chain. This structure ensures that once a block is added, it cannot be altered, providing a high level of security and transparency. Blockchain operates on a consensus mechanism, where all participating nodes must agree on the validity of transactions, reducing the risk of fraud and tampering. It is inherently transparent, allowing all participants to view and verify the entire transaction history, making it particularly useful for cryptocurrencies and smart contracts.

Banking ledgers, on the other hand, are centralized records maintained by financial institutions to track account balances and transactions. These ledgers are controlled by the bank, which has the authority to update and manage the records. This centralization means that while banks can efficiently handle a large volume of transactions, the system is more susceptible to fraud and errors. Transparency is limited, as only authorized personnel within the bank have access to the complete ledger, and customers can only see their own account information.

Blockchain offers a decentralized, transparent, and secure alternative to traditional banking ledgers, which are centralized and controlled by individual financial institutions with restricted access and lower transparency.
