+title: How to use Prune Node?
+weight: 3
+---
+
+## Preface
+
+The Pactus Blockchain supports pruned nodes to help users manage storage efficiently by retaining only
+the most recent and relevant data. This tutorial will guide you step-by-step on how to prune your node,
+whether using the command line or the graphical interface.
+
+## What is a Pruned Node?
+
+In the context of blockchain, a "pruned node" refers to a type of node that retains
+only a certain portion of the blockchain history, rather than the entire ledger.
+This is achieved by deleting old transaction data while maintaining the most recent and relevant blocks,
+often referred to as the "head" of the blockchain. This selective data retention allows nodes to
+operate without the need for extensive storage, enabling more participants to run nodes and contribute
+to network security and decentralization.
+
+## Key Features of Pruned Nodes
+
+1. **Storage Efficiency**: A primary advantage of pruned nodes is their reduced storage footprint.
+   This makes it feasible for users with limited hardware resources to run a node, thus increasing
+   the overall accessibility and decentralization of the network.
+
+2. **Faster Synchronization**: Because pruned nodes do not require the entire blockchain history,
+   they can sync with the Pactus network faster than full nodes. This facilitates quicker participation
+   in consensus and transaction validation.
+
+3. **Maintained Security**: Despite lacking full transaction history, pruned nodes still maintain enough
+   data to validate current transactions effectively. Therefore, they can participate in consensus
+   mechanisms without compromising network security.
+
+4. **Increased Participation**: By lowering the barriers to entry, pruned nodes can significantly
+   encourage more users to participate in staking and validating transactions, contributing to
+   a more robust and decentralized network.
+
+## Benefits of Pruned Solid State Proof of Stake Nodes
+
+1. **Scalability**: As the Pactus network grows, the size of the blockchain can become cumbersome.
+   Pruned nodes help mitigate this issue, allowing Pactus to scale efficiently without overwhelming infrastructure.
+
+2. **Energy Efficiency**: Coupled with the inherent efficiencies of Solid State Proof Of Stake, pruned nodes further
+3. reduce the environmental impact of Pactus operations. With fewer resources required for storage and data processing,
+   the Pactus network can operate more sustainably.
+
+4. **Enhanced Decentralization**: The ability for more participants to run nodes increases the decentralization of the network.
+   A more decentralized network is generally more resilient to attacks and manipulation, which bolsters the integrity
+   of the blockchain.
+
+5. **User Empowerment**: Pruned nodes empower users by making it easier for them to participate actively in the Pactus
+   ecosystem without needing significant technical expertise or substantial hardware investment.
+
+## How to Use a Pruned Node in Pactus?
+
+### Prune Your Full Node
+
+1. Stop your running full node with `CTRL+C`.
+2. Run the command
+
+```cmd
+./pactus-daemon prune -w <PATH-TO-WORKING-DIR>
+```
+
+3. Restart your pruned node with
+
+```cmd
+./pactus-daemon start -w <PATH-TO-WORKING-DIR>
+```
+
+### Initiate and Import New Pruned Node
+
+1. Download the Pactus CLI from [Pactus Downloads](https://pactus.org/download/).
+2. Open the Pactus directory (adapt the version as needed)
+
+```cmd
+cd pactus-cli_1.4.0
+```
+
+3. Import the pruned node with
+
+```cmd
+./pactus-daemon import -w <PATH-TO-WORKING-DIR>
+```
