DOT) is the native cryptocurrency of the Polkadot network, a "layer zero" protocol designed to connect and secure multiple specialized blockchains (called parachains).

Unlike traditional cryptocurrencies used only as digital money, the DOT token serves three distinct utility and infrastructure use cases:

1. Network Staking and Security

Polkadot uses a Nominated Proof-of-Stake (NPoS) consensus mechanism to protect the network. DOT holders lock up (stake) their tokens to act as or vote for trustworthy validators. In exchange for securing the multi-chain ecosystem, staking participants earn regular crypto rewards.

2. On-Chain Ecosystem Governance

The token grants absolute governance rights to its community through the Polkadot OpenGov system. DOT holders vote directly on network decisions, such as approving protocol upgrades, adjusting transaction fees, and managing the community treasury.

3. Purchasing Computational Coretime

To run an independent blockchain on Polkadot's secure infrastructure, developers must have access to the central Relay Chain's block space. DOT is used to purchase Agile Coretime, a dynamic, pay-as-you-go processing resource required to execute smart contracts and transmit cross-chain data safely.
