# What is Proof-of-Stake (PoS)? Proof-of-Stake (PoS) is a consensus mechanism that allows blockchain networks to validate transactions and secure the network without the need for energy-intensive mining. Instead of miners competing to solve complex mathematical problems, validators are chosen based on the amount of tokens they stake in the network. ### Key Features of PoS: * Energy-efficient compared to Proof-of-Work (PoW). * Validators are rewarded for maintaining the integrity of the network. * Higher transaction throughput and lower fees. * Reduced centralization risks compared to PoW. ### How Inertia Implements PoS and How It Works Inertia Chain uses a delegated Proof-of-Stake (DPoS) mechanism to enhance network efficiency. Validators and delegators work together to secure the network while earning staking rewards. Key Participants in the PoS Network: * Nodes: Maintain and verify blockchain data. * Validators: Stake IRTA Coin to validate transactions and secure the network. * Delegators: Users who stake their IRTA Coins with validators to earn rewards. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
