What is DOT?
Polkadot (DOT) FAQ
Polkadot allows multiple blockchains (called parachains) to run in parallel while sharing security through a central chain known as the Relay Chain. This enables scalability, high throughput, and secure interoperability between chains.
DOT is the native cryptocurrency of the Polkadot network and plays a critical role in its functionality. It is used for governance, allowing holders to participate in decision-making processes such as protocol upgrades and network policies. DOT also supports the network’s security through staking, where users lock up their tokens to validate transactions and earn rewards in return. Additionally, DOT is essential for bonding, a mechanism used to connect new parachains to the network by temporarily locking tokens during their onboarding process.
Polkadot uses on-chain governance where token holders, the Council, and the Technical Committee collaborate to propose and vote on changes. This transparent model enables continuous evolution of the network.
Polkadot’s security model is based on shared security through the Relay Chain and Nominated Proof of Stake (NPoS). Validators secure the network, while nominators support them by staking DOT. Disclaimer: it’s crucial to do your own research (DYOR) before engaging in any kind of investment.
