The Gemini dollar — the world’s first regulated stablecoin — combines the creditworthiness and price stability of the U.S. dollar with blockchain technology and the oversight of U.S. regulators. Get Gemini dollars 1-to-1 for U.S. dollars on Gemini. Gemini dollars can be used on the Ethereum network. ISSUER The Gemini dollar is issued by Gemini Trust Company, LLC, a New York trust company. BANK U.S. dollars that correspond to the Gemini dollars issued and in circulation are held at a U.S. bank and eligible for FDIC “pass-through” deposit insurance, subject to applicable limitations. EXAMINATION The U.S. dollar deposit balance is examined monthly by an independent registered public accounting firm to verify the 1:1 peg. All Independent Accountants’ Reports are published and available here. SECURITY AUDIT The Gemini dollar is a cryptographic token built on the Ethereum Network according to the ERC20 standard for tokens. The code of the Gemini dollar smart contracts has been audited by Trail of Bits, Inc., an information security research & development firm, whose report is publicly available here. Gemini was founded four years ago with a mission: build a bridge to the future of money. Gemini dollar aims to combine creditworthiness and price stability of the U.S. dollar with blockchain and the oversight of U.S. regulators, the New York State Department of Financial Service.

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.
