# Network Validation

GameChain network leverages a sophisticated consensus algorithm that not only promotes security but also incentivizes participant engagement through a fair and transparent validation process.

### Core Principles

The network's validation mechanism is built on three core principles:

* **Decentralization:** Ensuring the network remains protected against attacks and central points of failure by distributing validation power among a wide array of nodes.
* **Fairness:** Adopting a probabilistic approach to validator selection that rewards participants based on their stake, thus encouraging a healthy, competitive environment.
* **Security:** Implementing rigorous criteria and penalties for validators to safeguard against malicious activities and maintain network integrity.

### Validator Selection

Every five minutes, a new batch of validators is selected to verify the next block of transactions. This selection is based on a weighted random algorithm, where the probability of being chosen is directly proportional to the amount of $GAME tokens staked. The mechanism ensures that while larger stakeholders have a higher chance of being selected, smaller stakeholders still possess a significant opportunity to participate, thereby maintaining network decentralization.

#### Eligibility Criteria

To be eligible for selection as a validator, Game Nodes must:

* Own a Game Key license.
* Stake a minimum amount of $GAME tokens.

### Validation Process

Selected validators are tasked with verifying the transactions within their assigned block. This process is automatic and includes:

* Checking the validity of transaction signatures.
* Ensuring the transaction has not been previously included in the blockchain (double-spend prevention).
* Verifying that the transaction complies with network rules and protocols.

Upon successful validation, the block is proposed to the network to be added to the blockchain.
