Question

digitital cash has following characteristics​

Answer 1

Answer:

Digital cash aims to mimic the functionality of paper cash, by providing such properties of anonymity and transferability of payment. Digital cash is intended to be implemented data which can be copied, stored, or given as payment (for example, attached to an email message, or via a USB stick, bluetooth, etc). Just like paper currency and coins, digital cash is intended to represent value because it is backed by a trusted third party (namely, the government and the banking industry).

Ideal properties of a Digital Cash system

Ideal properties of a Digital Cash systemIdeal properties:

Secure. Alice should be able to pass digital cash to Bob without either of them, or others, able to alter or reproduce the electronic token.

Anonymous. Alice should be able to pay Bob without revealing her identity, and without Bob revealing his identity. Moreover, the Bank should not know who Alice paid or who Bob was paid by. Even stronger, they should have the option to remain anonymous concerning the mere existence of a payment on their behalf.

Portable. The security and use of the digital cash is not dependent on any physical location. The cash should be able to be stored on disk or USB memory stick, sent by email, SMS, internet chat, or uploaded on web forms. Digital cash should not be restricted to a single, proprietary computer network.

Two-way. Peer-to-peer payments are possible without either party required to attain registered merchant status (in contrast with today's card-based systems). Alice, Bob, Carol, and David share an elaborate dinner together at a trendy restaurant and Alice pays the bill in full. Bob, Carol, and David each should then be able to transfer one-fourth of the total amount in digital cash to Alice.

Off-line capable. The protocol between the two exchanging parties is executed off-line, meaning that neither is required to be host-connected in order to proceed. Availability must be unrestricted. Alice can freely pass value to Bob at any time of day without requiring third-party authentication.

Wide acceptability. The digital cash is well-known and accepted in a large commercial zone. With several digital cash providers displaying wide acceptability, Alice should be able to use her preferred unit in more than just a restricted local setting.

User-friendly. The digital cash should be simple to use from both the spending perspective and the receiving perspective. Simplicity leads to mass use and mass use leads to wide acceptability. Alice and Bob should not require a degree in cryptography as the protocol machinations should be transparent to the immediate user.

These are ideal properties, and no known system satisfies them all
