+
+As the blockchain industry grows, the demand for energy-efficient, secure, and decentralized solutions increases.
+At Pactus, we are committed to addressing these challenges by designing a blockchain network that
+provides sustainability without compromising performance and security.
+
+## Energy Efficiency at the Core of Pactus
+
+One of Pactus standout features is its ability to operate with minimal energy requirements.
+Unlike most blockchain networks that demand significant computational power or high-spec dedicated servers,
+Pactus validators can run on devices as energy-efficient as a
+[Raspberry Pi Zero](https://www.raspberrypi.com/products/raspberry-pi-zero/), which consumes just 2 watts of power.

+
+By leveraging affordable personal computers and shared Virtual Private Servers (VPS),
+Pactus ensures both energy efficiency and decentralization.
+This means more people can participate in our network without needing expensive, specialized hardware.
+
+## The Building Blocks of Efficiency
+
+### SSPoS Consensus Model
+
+At the heart of Pactus is the
+[Solid State Proof of Stake (SSPoS)](https://docs.pactus.org/protocol/consensus/proof-of-stake/) consensus model.
+This approach uses a fixed committee of 51 validators, which changes over time.
+The limited committee size reduces the complexity and the number of messages exchanged during consensus,
+enabling efficient network operations without compromising security or scalability.
+
+The dynamic nature of committee membership ensures that the network remains decentralized and secure,
+with validators regularly rotating based on a fair selection process.
+
+### Pruned Nodes
+
+Pactus supports [pruned nodes](https://docs.pactus.org/tutorials/pruned-nodes/),
+which store only the last 10 days of blockchain data instead of the entire transaction history.
+This innovation significantly reduces storage requirements—from gigabytes to just a few hundred megabytes—and
+allows new validators to sync with the network in just [few minutes](https://snapshot.pactus.org/).
+
+### User Friendly Interface
+
+Pactus offers both a user-friendly [GUI](https://pactus.org/download/#gui) and
+a powerful [CLI](https://pactus.org/download/#cli), providing flexibility for users of all levels.
+These interfaces make it simple for anyone to download and run Pactus on their chosen machine.
