# PoS Working Mechanism in Inertia Chain

1. Users stake IRTA Coin to participate in network validation.
2. Validators are selected based on their staked Coins and reputation.
3. Transactions are validated and added to the blockchain.
4. Validators earn rewards in IRTA Coins.
5. Delegators share in the rewards by staking their Coins with validators.

### Why Inertia is More Cost-Effective Than PoW Blockchains

* Lower Energy Consumption: PoW-based blockchains require significant computational power, whereas Inertia's PoS model is energy-efficient.
* Reduced Transaction Fees: Inertia Chain’s optimized PoS mechanism reduces transaction costs compared to PoW-based blockchains like Bitcoin and Ethereum.
* Faster Transactions: Higher throughput ensures quick confirmations with lower fees.
* Scalability: Unlike PoW networks, PoS-based Inertia Chain can handle more transactions per second, reducing congestion and improving cost-effectiveness.
