5.1.1.2 Parachain on Polkadot

The Integritee parachains are compatible with the polkadot-omni-node, therefore, there is no need to use Integritee's collator release. Instead, we recommend to use the latest polkadot-omni-node.

Spec Requirement

We suggest to meet these minimal requirements although slightly weaker HW may work as well:

• 2TB NVMe SSD.
  • seq. write performance should be > 1000 MB/s. Consider that SSD's get slower the more full they get. Also, they wear out with intense usage)
• 16GB RAM
• CPU won't matter much, but go for maximum single-core performance rather than many cores.

Build the Omni-Node

Skip this step if you want to use the pre-built binary.

We assume you're building on ubuntu 22.04

sudo apt update && sudo apt upgrade
sudo apt install -y build-essential clang curl git jq libssl-dev pkg-config protobuf-compiler
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
rustup target add wasm32-unknown-unknown
cargo install polkadot-omni-node

Run Collator as a Systemd Service

We assume you use ubuntu 22.04.
