Vincoin Cash idea

Vincoin Cash tries to help everyone to understand all the nuances of the crypto industry related to the blockchain because this technology is our future. Millions of people are interested in using blockchain technology, and can see the potential for profit, however, most of them don’t know anything about the world of cryptocurrency. Most people still perceive interaction with the cryptocurrency as something very complex, incomprehensible and not reliable. Vincoin Cash is the solution to this problem. We are on a mission to build a more open, accessible and fair financial future!

Why Vincoin Cash is different ?

Vincoin Cash is fungible
Vincoin Cash is fungible because it is private by default. Units of Vincoin Cash cannot be blacklisted by vendors or exchanges due to their association in previous transactions.
Unlinkable
Being a great feature, untreaceability doesn’t protect a receiver from defining his or her balance through inspecting incoming messages to the user’s public address.
Analysis resistant
Vincoin Cash blockchain analysis resistance results from its unlinkability, and is rarely analyzed by confused persons within the blockchain chain.vincoin.cash.
Vincoin Cash is untraceable
Sending and receiving addresses as well as transacted amounts are obfuscated by default. Transactions on the Vincoin Cash blockchain cannot be linked to a particular user or real-world identity.
Vincoin Cash increases your capital
Wallet encryption allows you to secure your wallet, so that a password is required before you can spend your coins.
No intermediaries/regulators
Vincoin Cash blockchain transactions are not affiliated to one person, and do not need KYC. Sending and receiving addresses are automatically hidden, which guarantee’s complete security.

Ring signatures: Untraceable payments

We solve this dilemma by automatic creation of multiple unique one-time keys, derived from the single public key, for each p2p payment. The solution lies in a clever modification of the Diffie-Hellman exchange protocol[1]. Originally it allows two parties to produce a common secret key derived from their public keys. In our version the sender uses the receiver's public address and his own random data to compute a one-time key for the payment.

Double-spending proof

Fully anonymous signatures would allow spending the same funds many times which, of course, is incompatible with any payment system's principles. The problem can be fixed as follows.

Key image via one-way function

All users keep the list of the used key images (compared with the history of all valid transactions it requires an insignificant amount of storage) and immediately reject any new ring signature with a duplicate key image. It will not identify the misbehaving user, but it does prevent any double-spending attempts, caused by malicious intentions or software errors.
