Union. Installing the node

10.09.2024, 17:26
Content:

The Union network is a highly efficient zero-disclosure infrastructure layer for universal messaging, asset transfers, NFT and DeFi. It is based on consensus verification and does not depend on trusted third parties, multisignatures or computational multilateral cryptography.

Minimum system requirements:

  • Node type: Testnet.
  • CPU: 4.
  • RAM: 8 GB.
  • Storage: 150 GB.

Installation

Automatic installation

Installation script:

wget -O uniont https://raw.githubusercontent.com/111STAVR111/props/main/Union/uniont && chmod +x uniont && ./uniont

Manual installation

Server preparation:

sudo apt update && sudo apt upgrade -y
sudo apt install curl tar wget clang pkg-config libssl-dev jq build-essential bsdmainutils git make ncdu gcc chrony liblz4-tool -y
