Polkadot (DOT), often called “Dot coin,” is a blockchain platform designed to connect multiple blockchains into a single unified network. Launched in 2020 by Ethereum co-founder Dr. Gavin Wood, it aims to solve one of blockchain’s biggest challenges—interoperability—allowing different chains to share data and assets securely.

Polkadot’s architecture is built around a central Relay Chain that provides security and consensus, while independent blockchains, known as parachains, run in parallel to increase scalability. This structure enables faster transactions and the ability to customize blockchains for specific use cases.

The DOT token serves three main purposes: governance (allowing holders to vote on network upgrades), staking (securing the network and earning rewards), and bonding (connecting new parachains).

Currently priced around $3.88 USD, DOT has experienced volatility but remains a key player in the Web3 and decentralized application space. With its focus on scalability, security, and cross-chain communication, Polkadot is positioned as a foundation for the next generation of blockchain innovation, appealing to both developers and long-term crypto investors.
