To demonstrate the use of zero-knowledge proofs, we are going to build a cryptocurrency service with similar functionality to the tutorial services in the Exonum All transactions are authenticated with the help of a digital signature cryptosystem, Ed25519, which is built into Exonum services.

Exonum: Byzantine fault tolerant protocol for blockchains. Conceived to expose remote infrastructures and services to application developers, most of the current Platform-as-a-services are based on proprietary technologies.

In this tutorial we create an Exonum service that implements a minimalistic cryptocurrency, and a single-node blockchain network processing requests to this service. The service accepts two types of transactions: creates a wallet with a default balance and transfers money between wallets.

exonum / private-currency. Watch 7. This is an Exonum service implementing a privacy-preserving cryptocurrency. The service hides the amounts being transferred among registered accounts (but not the identities of transacting accounts).

A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency's block chain contains every transaction ever executed in the currency.
