The reason why blockchain has not been applied on a large scale is that its infrastructure is not perfect, and even the largest Ethereum has some obvious defects. Therefore, the blockchain industry now needs to have a protocol to enable interoperability between various chains. Only by building roads on infrastructure to achieve interoperability, can more applications run on it. The future is the era of multi chain, and assets and information are interconnected.

Polkadot, based on Web3 0's underlying system is interconnected, and Polkadot 's cross chain function can also introduce other module resources, let them combine freely, and let Web3 give birth to more business ecology.

Based on this, we are optimistic about the future of Polkadot and the future ecological construction based on Polkadot！
