Polkadot is a decentralized platform that enables interoperability between different blockchain networks. This means that it allows for seamless communication and interaction between various blockchains, enabling the creation of a unified network.
In other words, Polkadot acts as a bridge between different blockchain ecosystems, allowing them to interact with each other in a secure and efficient manner.
To achieve this interoperability, Polkadot uses a unique approach called 'heterogeneous chains'. This means that it allows for multiple blockchain networks to coexist and interact with each other in a single network.
This is achieved through the use of relayers, which act as intermediaries between different blockchains. They ensure that transactions are securely relayed across different networks.
The importance of Polkadot lies in its ability to create a unified network, allowing for the creation of new use cases and applications. This can lead to increased adoption and mainstream acceptance of blockchain technology.
In addition, Polkadot's interoperability enables the creation of decentralized finance (DeFi) platforms that can interact with each other seamlessly.
