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.

Syscoin is “a global network, a distributed ledger, a decentralized database and a blockchain. It is also a cryptocurrency, an altcoin, a digital currency and a tradable token.” Originally launched in late 2014 and created through a Bitcoin fork, the current version brings us to Syscoin 2.1 and has an algorithm that allows it to be merge-mined with Bitcoin. Merge mining is simply the ability for miners to simultaneously mine two different cryptocurrencies based on the same algorithm. The project attempts to remove the middleman and put money directly back into merchants/consumers hands, eliminating hefty fees currently charged by big corporations like Amazon and eBay. To facilitate near-zero fee transactions, you can use its native cryptocurrency, Syscoin (SYS), to pay for goods on the marketplace. However, you can also pay using alternate cryptocurrencies such as Bitcoin or Zcash. Syscoin is led by a team of developers and was created by its current core developer, Sebastian Schepis. According to Proof of Developer, a website that verifies, evaluates, and ranks developer teams, Syscoin received 5 stars in 2014. Blockchain Foundry maintains Syscoin as its flagship product, with a mission to “disrupt markets by leveraging the potential of blockchain technology”. In March of 2017, Blockchain Foundry partnered with the Microsoft Azure ecosystem and is one of the founding members of the Digital Identity Foundation (DIF). Other founding members of the DIF include the likes of corporate giants such as Microsoft, Accenture, ConsenSys, and more. Syscoin’s blockchain delivers faster speeds along with lower transaction fees than its predecessor, Bitcoin. It can support 750 tps, and with the upcoming masternode release, it will support more than 300,000 tps. For now, it’s one of the cheapest cryptocurrencies regarding transaction fees (behind zero-fee transaction cryptocurrencies such as NEO and NANO), even cheaper than XRP.' Some of the features highlighted on the SysCoin website includes :- 1. Buy/Selling goods on the blockchain 2. Brokerage on the blockchain 3. Issue and trade certificates on the blockchain 4.
