Running a full node on the SUI blockchain is essential for network decentralization, validating transactions, and contributing to the blockchain ecosystem. This guide provides detailed instructions on setting up a SUI full node, including hardware requirements, installation steps, cost estimates, and best practices.
What is a Full Node on SUI?
A full node is a server that maintains a complete copy of the SUI blockchain, validating transactions and blocks without relying on third parties. Running a full node is crucial for:
- Decentralization – Contributing to the security and resilience of the network.
- Transaction Verification – Ensuring the accuracy and integrity of blockchain data.
- Data Access – Providing an API endpoint for applications interacting with SUI.
- Participation in Governance – Allowing more direct interaction with the SUI network.
System Requirements for Running a SUI Full Node
1. Hardware Requirements
| Component | Minimum Requirement | Recommended Requirement |
|---|---|---|
| CPU | 4-core (x86_64) | 8-core or more (x86_64) |
| RAM | 16 GB | 32 GB or more |
| Storage | 1 TB SSD (NVMe) | 2+ TB SSD (NVMe) |
| Network | 100 Mbps | 1 Gbps+ |
| OS | Ubuntu 22.04 LTS | Ubuntu 22.04 LTS |
2. Estimated Costs for Running a Full Node
| Service Provider | Estimated Monthly Cost (Minimum Setup) |
|---|---|
| AWS (EC2) | $100 – $300 |
| DigitalOcean | $80 – $200 |
| Vultr | $75 – $180 |
| Hetzner | $50 – $120 |
| Bare Metal Server | $150 – $500 |
Step-by-Step Guide: Installing a SUI Full Node
Step 1: Update System and Install Dependencies
sudo apt update && sudo apt upgrade -y
sudo apt install -y curl wget git build-essential clang cmake pkg-config libssl-devStep 2: Install Rust and Cargo
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
rustc --versionStep 3: Clone the SUI Repository
git clone https://github.com/MystenLabs/sui.git
cd suiStep 4: Build and Compile SUI
cargo build --releaseStep 5: Configure the Full Node
mkdir -p ~/sui-node
cd ~/sui-node
wget -O fullnode.yaml https://github.com/MystenLabs/sui/blob/main/crates/sui-config/data/fullnode-template.yamlStep 6: Start the SUI Full Node
RUST_LOG=sui=info ./sui-node --config-path fullnode.yaml
‘Participation in Governance’ sounds cool! I want to be part of that.
I love how detailed the instructions are. Thanks for sharing!
“Decentralization” sounds nice, but does anyone actually care about running their own node?
This guide is too technical. I bet most people will just stick to third-party services.
“API endpoint for applications”? Who even needs that? Most people just want to use crypto!
Seems like running a full node is only for tech geniuses! What about the rest of us?
Great post! I learned a lot about the importance of decentralization.
What if something goes wrong? Are there support options for running a full node?
Why do we need a full node anyway? This sounds too complicated for regular users.
I’m so excited to start my own full node after reading this!
“Estimated costs” are unrealistic. How is anyone supposed to start with these prices?
‘Participation in Governance’? Sounds like a fancy way to say ‘more work for us’.
I don’t see the point of all this hardware. Can’t we just trust others to run the nodes?
Wow, this makes it easy to understand how to contribute to SUI!
‘Transaction Verification’ is super important. Thanks for explaining it well!
Fantastic breakdown of requirements! I appreciate it!
Running a full node sounds exciting! I’m ready to dive in.
$100 a month? That’s way too expensive! How can anyone afford that?
This guide is so helpful! I can’t wait to set up my own SUI full node!
