Global Dollar (USDG) vs Zcash (ZEC)

Global Dollar (USDG) is a single currency stablecoin pegged to the US dollar that is regulated under the Monetary Authority of Singapore (MAS). USDG is issued by Paxos Digital Singapore (PDS) and will always be fully redeemable from Paxos on a one- to-one basis for US dollars. USDG combines the stability and reach of US dollars with the added security and efficiency of blockchain technology. USDG is always available and accessible, offering high transfer speeds and programmability. USDG is always available for 1:1 redemption for US dollars, 24/7. Paxos Digital Singapore Pte. Ltd. (PDS), the issuer of USDG, has secured full approval from the Monetary Authority of Singapore (MAS) as a Major Payments Institution (MPI) to offer digital payment token services. This approval aligns USDG with MAS' forthcoming stablecoin framework, positioning it at the forefront of regulatory compliance. MAS, a globally recognized prudential regulator, is known for its robust oversight of stablecoins and commitment to stringent consumer protection standards. USDG's issuance will adhere to strict regulatory standards, including requirements for value stability, capital adequacy, redemption and par and comprehensive disclosure. Specific regulatory obligations include substantial capital reserve requirements, frequent regulatory examinations, monthly independent attestations of reserve assets, monitoring of operating procedures and annual audits of reserve assets. It also provides protection from bankruptcy by holding stablecoin reserve assets in segregated accounts held on trust by PDS for the benefit of USDG holders. USDG represents the pinnacle of regulated stablecoins, offering unparalleled stability, security and compliance in the rapidly evolving world of digital finance.

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.
