Cryptocurrency Advanced: Service with Data Proofs

The extended version of the Cryptocurrency Service implementing data proofs. This project demonstrates how to bootstrap your own cryptocurrency with Exonum blockchain.

See the documentation for a detailed step-by-step guide how to approach this example.

Cryptocurrency demo

Exonum blockchain keeps balances of users and handles secure transactions between them.

It implements most basic operations:

  • Create a new user
  • Add funds to the user's balance
  • Transfer funds between users

Install and run

Using docker

Simply run the following command to start the cryptocurrency service on 4 nodes on the local machine:

docker run -p 8000-8008:8000-8008 exonumhub/exonum-cryptocurrency-advanced:demo

Docker will automatically pull image from the repository and run 4 nodes with public endpoints at, ..., and private ones at, ...,

To stop docker container, use docker stop <container id> command.


Getting started

Be sure you installed necessary packages:

Install and run

Below you will find a step-by-step guide to starting the cryptocurrency service on 4 nodes on the local machine.

Build the project:

git clone

cd exonum/examples/cryptocurrency-advanced/backend

cargo install --path .

Generate template:

mkdir example

exonum-cryptocurrency-advanced generate-template example/common.toml --validators-count 4

Generate public and secrets keys for each node:

exonum-cryptocurrency-advanced generate-config example/common.toml  example/pub_1.toml example/sec_1.toml --peer-address -c example/consensus_1.toml -s example/service_1.toml -n

exonum-cryptocurrency-advanced generate-config example/common.toml  example/pub_2.toml example/sec_2.toml --peer-address -c example/consensus_2.toml -s example/service_2.toml -n

exonum-cryptocurrency-advanced generate-config example/common.toml  example/pub_3.toml example/sec_3.toml --peer-address -c example/consensus_3.toml -s example/service_3.toml -n

exonum-cryptocurrency-advanced generate-config example/common.toml  example/pub_4.toml example/sec_4.toml --peer-address -c example/consensus_4.toml -s example/service_4.toml -n

Note that in case of copying files with consensus and service keys to the other machines, you must change the access permissions of these files for every machine. For example:

sudo chmod 600 consensus_1.toml
sudo chmod 600 service_1.toml

Finalize configs:

exonum-cryptocurrency-advanced finalize --public-api-address --private-api-address example/sec_1.toml example/node_1_cfg.toml --public-configs example/pub_1.toml example/pub_2.toml example/pub_3.toml example/pub_4.toml

exonum-cryptocurrency-advanced finalize --public-api-address --private-api-address example/sec_2.toml example/node_2_cfg.toml --public-configs example/pub_1.toml example/pub_2.toml example/pub_3.toml example/pub_4.toml

exonum-cryptocurrency-advanced finalize --public-api-address --private-api-address example/sec_3.toml example/node_3_cfg.toml --public-configs example/pub_1.toml example/pub_2.toml example/pub_3.toml example/pub_4.toml

exonum-cryptocurrency-advanced finalize --public-api-address --private-api-address example/sec_4.toml example/node_4_cfg.toml --public-configs example/pub_1.toml example/pub_2.toml example/pub_3.toml example/pub_4.toml

Run nodes:

exonum-cryptocurrency-advanced run --node-config example/node_1_cfg.toml --db-path example/db1 --public-api-address --consensus-key-pass pass --service-key-pass pass

exonum-cryptocurrency-advanced run --node-config example/node_2_cfg.toml --db-path example/db2 --public-api-address --consensus-key-pass pass --service-key-pass pass

exonum-cryptocurrency-advanced run --node-config example/node_3_cfg.toml --db-path example/db3 --public-api-address --consensus-key-pass pass --service-key-pass pass

exonum-cryptocurrency-advanced run --node-config example/node_4_cfg.toml --db-path example/db4 --public-api-address --consensus-key-pass pass --service-key-pass pass

Install frontend dependencies:

cd ../frontend

npm install

Build sources:

npm run build

Run the application:

npm start -- --port=8280 --api-root=

--port is a port for Node.JS app.

--api-root is a root URL of public API address of one of nodes.
