The KUB PoS mechanism provides several benefits, including energy efficiency, scalability, faster transactions, and strong security measures that ensure network integrity, enable nodes to operate correctly, and enhance the security and decentralization of the blockchain network. ## Staking on KUB Network [Staking](/run-a-kub-node/run-a-validator-node/validator-staking.md) involves depositing the KUB Coin to activate the validator. A validator's role includes storing data, processing transactions, and adding blocks to the blockchain. This active participation helps secure the KUB network, benefiting all users and allowing validators to earn additional KUB Coin rewards. ## Validators A [validator](/run-a-kub-node/becoming-a-validator.md) is a group of individuals who validate transactions on the KUB network to ensure their security and the decentralization of KUB. ### Pool Node A pool node on the KUB network allows delegators to delegate their KUB Coin to this node type, increasing staking power and the chances of the node validator to mine a block on the KUB network. Those considering pool staking should have at least 100,000 KUB and a computer connected to the internet, which must maintain 100% uptime. ## Delegators [Delegators](/governance/delegate-kub-coin.md) are groups of individuals who participate in validating transactions with the validators. The delegators jointly stake the KUB coin with the validator to delegate authority to the validator to validate the transaction. The delegators receive rewards based on the proportion of staking power under which the delegator can do without its technical knowledge or infrastructure. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.kubchain.com/run-a-kub-node/overview.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
