Verifiability in digital currencies refers to the ability to check the accuracy of transactions without the need for a central authority or third party. Bitcoin operates on an open-ledger network, meaning that all transactions are publicly recorded and can be independently verified by anyone on the network.

This allows for greater transparency and accountability in the financial system, as all transactions can be tracked and audited. Verifiability helps to reduce the risk of fraud and enhances trust in the digital currency system, as users can verify the accuracy of their transactions and balances.

In summary, verifiability in digital currencies ensures that all transactions are accurate, transparent, and can be independently verified without relying on central authorities or third parties. This helps to promote trust and security in the digital currency system.
