With the maturity of the heterogeneous cross-chain protocol Polkadot (Polkadot), the blockchain will enter the era of multi-chain interconnection. Polkadot connects multiple different parachains together. Parachains can interact and collaborate with multiple chains. Just like computers in the Internet era, they can carry more and richer distributed applications.

Polkadot is undoubtedly the best blockchain framework for building a full set of commercial infrastructure, and Substrate aims to provide developers with tools for developing Web3.0 applications and products.

They believe that the Polkadot ecology will produce a large number of brand-new distributed applications. In order to help the Polkadot ecological development and cultivate more Web3.0 infrastructure and applications, They launched the "Polkadot Hackathon" to help Substrate developers better follow suit. 0 to 1 Form a team and start a landing project to build innovative products of the Polkadot ecology. The winning team will receive generous bonuses, technical and resource support, and become a member of the Polkadot ecology in a true sense.

The second summer Polkadot Hackathon Developer Entrepreneurship Competition was officially opened on May 13th . It was co-hosted by Parity, Web3 Foundation, OneBlock+ community and PolkaWorld, and co-sponsored by IOSG, SNZ, Hashkey, Fenbushi Capital and Multicoin.

7. Technical resource reference

Substrate allows you to create a customized blockchain by making and integrating different modules. It comes with everything needed to build a blockchain. Using the Substrate module, you can easily create the content you need, or make your own custom logic, making the construction of the blockchain faster, easier, and safer than ever.

Include:

• Chain upgrade without hard fork: Upgrading the blockchain has never been easier. With Substrate, upgrading on-chain logic is as easy as submitting a transfer transaction.

• Cross-language support for WebAssembly : WebAssembly is the next web standard. You can write your blockchain logic in any language, including C/C++, C#, Typescript and Rust, and then compile it to WebAssembly format.

• Directly compatible with the Polkadot network: Your Substrate blockchain will be compatible with the Polkadot network, so that it can easily become a parachain of the Polkadot network and communicate with other chains.

• Future-oriented blockchain: With functions such as no-fork on-chain upgrades, lightweight clients, and off-chain working machines, your Substrate blockchain is ready for the innovation brought about by future Web 3.0.
