(from old site) Offers total payment confidentiality, while still maintaining a decentralized network using a public blockchain. Transactions automatically hide the sender, recipient, and value of all transactions on the blockchain. Only those with the correct view key can see the contents. Users have complete control and can opt-in to provide others with their view key at their discretion. Uses a novel cryptographic method to verify payments. Uses a zero-knowledge proof construction called a zk-SNARK. 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.
