Polkadot Hackathon 2022 co-hosted by Parity Technology and OneBlock is in full swing.Up to now, 30+ teams and over 130 developers from China, Germany, Nigeria, South Korea, Australia, Argentina, and other global areas have registered.At present, 20% of registration came from overseas participants, while 80% are Chinese participants.
The registration for Polkadot Hackathon 2022 is still open.There are individual participants looking for teammates and open seats in some teams.Beyond the developers, we are also looking for talents in UI, product design, operations, etc.
If you have relevant skill sets, you are also very welcome to participate in our hackathon and organize your team to build the project.Please join our Discord to find the best-match team and teammate for you and hone your skill together with us!
Developer Resources In order to better support the development experience of all hackathon participants, we prepared developer resources and guides for all of you.You can read through the following documents, tutorials, and courses to familiarize yourself with Substrate and Polkadot, which would help you to create the best hackathon project with ease.
Substrate allows you to customize blockchain by making and integrating different modules.
It comes with everything you need to build a blockchain.Using the Substrate module makes it easy to create the content you need and your own custom logic, making building blockchains faster, easier, and more secure than ever.
It has the following features:
Upgrade without Hard Fork Nodes: Upgrading a blockchain has never been easier.
With Substrate, upgrading on-chain logic is as easy as submitting a transaction.WebAssembly Cross-Language Support : WebAssembly is the next-generation Web standard.You can develop blockchain in any programming language, including C/C++, C#, Typescript, and Rust, and then compile it into WebAssembly format.Directly Compatible with Polkadot networks : All Substrate-based chains are seamlessly compatible with Polkadot, which can be easily integrated into Polkadot to become a parachain or parathread.Future-Proof : Features like On-chain upgrades without hard fork nodes, light client, and offchain workers empower Substrate blockchain to drive the future innovation of Web 3.0.1) For Beginners in Substrate/Polkadot：
Official Substrate Docs
Here are the most comprehensive explanations of Substrate technical knowledge.
It covers content from basic principles to design decisions that Substrate is built on as well as the specific skills needed to be an effective Substrate blockchain developer.It is the best entry point for beginners to get a head start in Substrate.Substrate Tutorial
https://substrate.dev/en/tutorials
A step-by-step tutorial about how to use Substrate to develop your own dApps and build frontends to interact with them.You can start with on-chain storage applications.Substrate Basics 101 Chinese Course
Substrate Basic 101 Chinese Course is jointly created by the official engineers of Parity Technology APAC and OneBlock+ community.There are six online video tutorials and coding assignments after each class to help learn Substrate from 0 to 1.Polkadot Official Docs
https://wiki.polkadot.network/docs/en/learn-launch
Detailed explanations about a part of Polkadot network behaviors and principles.Polkadot-JS
