Polkadot is a cross-chain network protocol created by Ethereum co-founder Dr. Gavin Wood, designed to connect public chains, private chains, consortium chains, oracles, and other Web3 applications. Its core idea is to achieve communication and data transfer between multiple chains through the Relay Chain, breaking down the information silos of a single blockchain.

Polkadot adopts a heterogeneous multi-chain architecture, where each parachain can customize its logic according to its own needs while sharing the security of the entire network.

What are the functions of DOT?

DOT is the native token of the Polkadot network, and it mainly serves the following three roles:

1. Governance: Users holding DOT can participate in proposals, voting, and protocol upgrades on the Polkadot network.
2. Staking: Supporting validators by staking DOT to ensure the security and consensus mechanism of the network.
3. Bonding: Developers need to lock up DOT to apply for deploying their own parachain.

What are the technical highlights of Polkadot?

1. Heterogeneous multi-chain structure: Polkadot supports the parallel operation of different types of blockchains, allowing each chain to focus on specific tasks.
2. Cross-chain interoperability: Trust-minimized information transfer and asset exchange through relay chains.
3. Scalability: Multiple parallel chains can process transactions simultaneously, achieving high throughput performance.
4. Upgrade mechanism: Network upgrades can be performed without hard forks, ensuring continuous technological evolution.
5. Improved governance mechanism: Community governance is conducted through on-chain voting, which is transparent and efficient.

The relationship between DOT and investors

As a token, DOT’s value is reflected not only in the trading market but also in ecological governance and network maintenance. For ordinary investors, holding DOT represents:

• You can earn rewards through staking;
• can participate in important decisions;
• There is an opportunity to support potential projects launching on the Polkadot ecosystem.

How is DOT performing in the current market?

As of June 2025, the price of DOT is around $4. Although it has fallen from its historical peak, the technical value of Polkadot is gradually gaining market recognition, driven by the expansion of Web3 applications and the cross-chain auction mechanism. However, investors still need to trade cautiously and be aware of the risks.

Summary:

What is DOT? It is not only the economic engine of Polkadot, but also the key to the multi-chain world of Web3. For users who want to participate in the future of the internet, understanding DOT and Polkadot is the first step into the cross-chain era.
