'Solve.Care is a healthcare IT company that builds blockchain platforms which the team believes may improve the way healthcare is delivered and managed. The Solve.Care platform reportedly uses blockchain technology as the underlying distributed ledger for coordinating care, benefits and payments between all parties in the chain of healthcare: patients, doctors, pharmacies, laboratories, employers, insurers, and others. SOLVE tokens may be used to secure efficient and transparent healthcare administration around the world. The token supply is fixed and the price variable, as determined by market supply and demand. SOLVE token runs natively on the Ethereum blockchain and is designed to follow the ERC20 token standard. SOLVE utility tokens are the currency used for transactions on the platform. According to the foundation, they can be utilized to pay for Care Administration Network fees, establish Care.Wallets, purchase Care.Cards, and participate in Care.Marketplace services as well as pay for associated integration fees. In addition, SOLVE is reportedly used for the emission of Care.Coins and payments requiring Care.Coins.'
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.
