Zcash is a decentralized and open-source cryptocurrency that offers privacy and selective transparency of transactions. Zcash payments are published on a public blockchain, but the sender, recipient, and amount of a transaction remain private. Zcash is based on peer-reviewed cryptographic research, and built by a security-specialized engineering team on an open source platform based on Bitcoin Core's battle-tested codebase. Our improvement over Bitcoin is the addition of privacy. Zcash uses advanced cryptographic techniques, namely zero-knowledge proofs, to guarantee the validity of transactions without revealing additional information about them. How Zcash works Zcash encrypts the contents of shielded transactions. Since the payment information is encrypted, the protocol uses a novel cryptographic method to verify their validity. Zcash uses a zero-knowledge proof construction called a zk-SNARK, developed by our team of experienced cryptographers based on recent breakthroughs in cryptography. These constructions allow the network to maintain a secure ledger of balances without disclosing the parties or amounts involved. Instead of publicly demonstrating spend-authority and transaction values, the transaction metadata is encrypted and zk-SNARKs are used to prove that nobody is cheating or stealing. Zcash also enables users to send public payments which work similarly to Bitcoin. With the support for both shielded and transparent addresses, users can choose to send Zcash privately or publicly. Zcash payments sent from a shielded address to a transparent address reveal the received balance, while payments from a transparent address to a shielded address protect the receiving value.

Gulden is a second-generation peer-to-peer cryptocurrency which was created to provide a secure, simple and fast method of performing financial transactions between private individuals, customers & service providers and also corporate entities. Like many recent cryptocurrencies, the primary design criteria were to improve the security and usability of the currency and its underlying transaction authorisation technology (when compared to the original cryptocurrency - Bitcoin). The purpose of these changes was to simplify use and increase its adoption as a convenient, cheap and safe form of payment. The original initiative for this currency came from Rijk Plasman with the first working implementation released on the 4th April 2014. Initially called the “Gulden coin”, this was subsequently abbreviated in October 2015 to “Gulden”. The name Gulden comes from the German and Dutch term for “gold coin” and is the Dutch name of the Dutch guilder, the pre-euro currency of the Netherlands. Gulden Coin is the currency that enables the user to pay safely, conveniently and quickly. Moreover, it is a lucrative investment opportunity at the moment, considering that since entering the market in 2016 the developers have increased to a market capital of 39,883,259 USD with about 800,000 USD. The model of making cryptocurrencies accessible to ordinary consumers in the future holds enormous potential in the fintech sector.
