eCurrency Node Installation

eCurrency Node is the core service for running and maintaining the eCurrency blockchain. It can be built and deployed using Docker or installed locally via make.

Source code

git clone https://github.com/ecurrency-project/ecurrency-pos.git
cd ecurrency-pos

---

Installation method 1: Docker image

If you have Docker or Podman installed, pull the prebuilt node image from Docker Hub:

docker pull ecurrency/ecurrency

Alternatively, if you prefer to build the image from source yourself (for example, to verify it or after modifying the code), you can build it directly from the ecurrency-pos directory:

make docker

If you prefer to use Podman, edit the Makefile and replace the word docker with podman. Make sure you have make installed on your system.

The simplest way to run the node is to let Docker itself keep the container running (including across reboots) by starting it with the --restart=unless-stopped policy:

docker run -d --restart=unless-stopped --mount type=bind,source=/etc/qecurrency.conf,target=/etc/qecurrency.conf,readonly --volume /home/qecurrency/database:/database --read-only -p 9666:9666 -p 127.0.0.1:9669:9669 --name qecurrency ecurrency/ecurrency

If you built the image locally with make docker, use the image name qecurrency instead of ecurrency/ecurrency.

The Docker image also provides a web admin interface with a blockchain explorer and a wallet on port 9669. Run the container with this port published for localhost only (-p 127.0.0.1:9669:9669, as in the example above), then open it in your browser:

http://127.0.0.1:9669

If you are going to use the wallet, it is recommended to first set a password there, in the same web admin interface.

Alternatively, you can run the container as a systemd service — useful if you want logging to a file, running the node under a dedicated user, restart limits, or managing it alongside other system services. An example unit file can be found at:

systemd/system/qecurrency-docker.service

Once the node is running inside a Docker container, you can define a convenient alias:

alias qecurrency-cli='docker exec qecurrency qecurrency-cli'

Then you can verify the node is responding:

qecurrency-cli help

This should print the list of available node commands.

Running and usage

The node uses the following network ports:

• 9666 — peer-to-peer communication between nodes
• 9667 — management interface for qecurrency-cli (by default bound to localhost)
• 9668 — for REST API (disabled by default, can be enabled in the configuration file)
• 9669 — web admin interface with explorer and wallet (Docker image only, should be bound to localhost)

Make sure these ports are open in your firewall if required.

Basic CLI commands

qecurrency-cli help
qecurrency-cli help <command>

Main commands:

Command	Description
getnewaddress	Generates a new address and its private key
importkey <private-key>	Imports an existing private key
getaddressbalance <address>	Shows the balance of the specified address
listunspent <address>	Lists unspent outputs (UTXOs) for an address
createrawtransaction <inputs> <outputs>	Creates a new transaction
signrawtransactionwithkey <hexstring> <privatekeys>	Signs a transaction
sendrawtransaction <hexstring>	Broadcasts a signed transaction

---

Mining and rewards

After importing your private keys, they are used for block validation (if the node runs with generate=1, which is the default). In this case, the node will participate in block generation and gradually earn rewards — you will see your balance increase over time.
