Running RNode (non-Docker)

Rnode is the instance, where the smart-contracts are executed. This chapter describes, how to install and setup the rnode instance on your pc and connect to an existing network.

Install RNode

We deliver RNode software in a variety of installation packages. Installation packages are available at both RChain and Github. We recommend using the latest release.

In the command examples below, you must update based on the version number of RNode you want by replacing "x" with the numbers in your installation version.

Should there be errors, when you install RNode for the first time, please make shure that you have the newest Java version installed.

Linux

This part describes, how to setup a rnode instance on linux

Install JDK (Java)

The rnode instance for linux needs the Java JDK preinstalled. Many distribution have this included into their os.

sudo apt-get update
sudo apt-get install -y software-properties-common
sudo add-apt-repository -y ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install -y openjdk-11-jdk

sudo systemctl stop rnode && dnf remove rnode && rm -rf /var/lib/rnode/rspace && sudo dnf install ./rnode-x.x.x-1.noarch.rpm
Other Linux distributionsTarball (.tgz)Prerequisites
Java - We recommend Open JDK 11, https://openjdk.java.net/projects/jdk/11/

Libsodium - https://download.libsodium.org/doc/ installed in a standard prefix (/user or /user/local)

First time installation:
tar -xvf rnode-x.x.x.tgz
cd rnode-0.x.x
./macos_install.sh

Note:
The macos_install.sh script installs the Homebrew package manager on your machine and then installs libsodium.
If you already have Homebrew installed on your machine, you can refer to the script for how to install libsodium directly.

ARM

You can run RNode on Raspberry pi. An example of this, including installation and deployment instructions, is available at https://github.com/kayvank/arm-rnode.

To connect to an existing network

Please fill in the <bootstrap ID>. The current network ID is posted on RChain public testnet information.

rnode run --network-id <arg> --shard-id <arg> --bootstrap <arg> --finalization-rate <arg> --fault-tolerance-threshold <arg> --synchrony-constraint-threshold <arg> --fork-choice-stale-threshold <arg> --fork-choice-check-if-stale-interval <arg> --drop-peer-after-retries <arg> --give-up-after-skipped <arg>
  • --network-id <arg> The network to run on (testnet , mainnet).
  • --shard-id <arg> The network is splitted into shards for scaling.
  • --bootstrap <arg> The bootstrap server for initial connection to the network.
  • --finalization-rate <arg> Block finalization is triggered after adding every 'n' blocks. Use this option to configure this.
  • --fault-tolerance-threshold <arg> Float value representing that the node tolerates up to fault-tolerance-threshold fraction of the total weight to equivocate.
  • --synchrony-constraint-threshold <arg>Float value representing that the node waits until at least synchrony-constraint-threshold fraction of the validators (by stake weight) proposed at least one block since is node's last proposal.
  • --fork-choice-stale-threshold <arg> Node will request for fork choice tips if the latest FCT is more then ForkChoiceStaleThreshold old.
  • --fork-choice-check-if-stale-interval <arg> Interval for check if fork choice tip is stale.
  • --drop-peer-after-retries <arg> Fair round robin dispatcher drop inactive peer after round robin rounds. After giving up several times the peer gets dropped from the queue.
  • --give-up-after-skipped <arg> Fair round robin dispatcher give up and try next peer after skipped packets. Skipped packets are buffered in other peers packet queues.

Examples:

  • run rnode
./rnode run --network-id mainnet --shard-id root --bootstrap "rnode://487e2c0c519b450b61253dea0a23b4d184a50089@node0.root-shard.mainnet.rchain.coop?protocol=40400&discovery=40404" --finalization-rate 1 --fault-tolerance-threshold -1 --synchrony-constraint-threshold 0 --fork-choice-stale-threshold 30minutes --fork-choice-check-if-stale-interval 30minutes --drop-peer-after-retries 0 --give-up-after-skipped 0
  • help documentation
./rnode --help

if the message: - Waiting for first connection is there for more than 1 minute, please check your ports and ip: Network Configuration
