# Consensus and Security

### Consensus Mechanism

* **Proof of Stake (PoS)**: Nodes participate in the consensus process by staking a certain amount of tokens, which helps secure the network. Nodes are chosen to create new blocks based on their stake, promoting fairness and energy efficiency.
* **Slashing**: To discourage dishonest behavior, nodes that act maliciously or fail to fulfill their responsibilities can have a portion of their stake "slashed" or removed.

### Security Audits & Updates

* **Regular Audits**: Continuous security audits are conducted to identify and mitigate potential vulnerabilities in the smart contracts and node software.
* **Dynamic Updates**: The blockchain supports on-chain governance for dynamically updating network protocols and algorithms to respond to emerging security threats or performance bottlenecks.
