Development technical guide | the most complete technical documents, tutorials and courses of substrate and Polkadot

Substrate It allows you to create customized blockchains by making and integrating different modules . It comes with everything you need to build a blockchain . Use Substrate Modules make it easy to create what you need , Or make your own custom logic , Give Way Building blockchains is faster than ever , More relaxed , More secure .

It has ：

• No hard forked chain upgrade required ： Upgrading the blockchain has never been easier . It was used Substrate, Upgrading chain logic is as easy as submitting a transfer transaction .

• WebAssembly Cross language support for ：WebAssembly It's the next one Web standard . You can write your blockchain logic in any language , Include C / C ++,C＃,Typescript and Rust, Then compile to WebAssembly Format .

• Direct compatibility Polkadot The Internet ： Your Substrate Blockchain will work with Polkadot Network compatibility , So you can easily become Polkadot Parallel chains of networks , And communicate with other chains .

• Future oriented blockchain ： Upgrade on the Forkless chain , Lightweight client and Off chain machine And so on , Your Substrate Blockchain is the future Web 3.0 Ready for innovation .
