Paxos Standard (PAX) was created by Paxos, a financial technology company on a mission to modernize finance by mobilizing assets at the speed of the internet. Paxos was the first virtual currency company to receive a charter from the New York State Department of Financial Services. As a chartered limited purpose trust company with fiduciary powers under the Banking Law, Paxos is able to offer regulated services in the crypto-asset and virtual commodities space. The Paxos team comes from a wide variety of backgrounds with a diverse array of experiences ranging from Wall Street to Silicon Valley. It’s led by CEO and co-founder Charles Cascarilla, who has spent his career as a customer, analyst, investor and now creator of financial technology. Paxos describes itself as “the first regulated Trust company with blockchain expertise”, and it is using that expertise to create a modern settlement solution that can eliminate risk and simplify settlements. What many people may not know about Paxos is that it was actually founded in 2012 as Paxos Trust Company, and that for most of its life it ran the cryptocurrency exchange itBit, which is still operates. The creation of Paxos was a pivot from an exchange platform to a company focused on creating a modern settlement platform using blockchain technology. Paxos has become the most widely adopted cryptocurrency in the fastest time frame, with support from over 20 exchanges and OTC desks in the first five weeks of its existence. It’s been picked up and listed by six of the top ten cryptocurrency exchanges, Binance, OKEx, Gate.io, ZB, KuCoin and DigiFinex. These exchanges are offering PAX as an alternative to the controversial Tether. Unlike the controversy surrounding the people who control Tether, there is no such obscurity when it comes to the people behind Paxos. The CEO and co-founder is Charles Cascarilla. He has over 15 years in financial services and has co-founded Cedar Hill asset management back in 2005. He has also worked and Bank of America and Goldman Sachs prior to that. The Paxos Standard (PAX) is the first digital asset to be issued by a financial institution and to be fully secured by the U.S. dollar. While other similar stablecoins have existed, there has been no proof of full U.S. dollar reserves, nor have these earlier assets been issued by a financial institution. The Paxos team has been fairly clear in declaring the different base that PAX is working from.
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.
