Substrate - is considered as one of the three core technologies that make up the future Web3 vision. Substrate is commonly used in Polkadot's ecosystem.

So what is Substrate? Why is the Substrate Framework mentioned so much?

What is Substrate?

Substrate is a modular framework for building and developing blockchain projects. This modular framework allows developers to build various blockchains based on libraries with custom or ready-made components. The creator of this tool is Dr. Gavin Wood, Co-Founder of Ethereum.

Each project represents different functions on Parachain. These projects are built using the Substrate engine. We can create these projects in other languages, but we can simplify and cut down on a lot of the time required for the process with the Substrate tool.

Notable Features of Substrate

  • Substrate is inherently integrated with the BFT (Byzantine Fault Tolerance) consensus algorithm, thus ensuring that the blockchain remains active in the event of one or more nodes being down, or disabled.
  • A peer-to-peer (P2P) network
  • Provides a WebAssembly developer toolkit to ensure high-performance developed applications.

Benefits of Substrate

  • Substrate is the fastest way to create a blockchain - Substrate will most likely solve the hardest problems for you such as the data layers and the consensus mechanism. To get started, simply use the default options and you're good to go!
  • Substrate is new, but very popular - Although it has only been released since 2018, there are now more than 170 projects using Substrate.
  • Substrate is more flexible than other blockchain networks - You are completely free to choose custom blocks or develop your own blocks using Substrate. Even with smart contracts, you can completely build your own, as long as you make sure that your blockchain can work.
  • To become a blockchain developer, Substrate is the fastest way - Substrate uses Rust language, quite similar to JavaScript in command line, but similar to C++ in terms of logic. So if you only know JS, you will waste no time getting used to Rust.

Notable Substrate Structure and Compatibility

Notable structure

  • Built on WebAssembly;
  • Industry Standard Networking Libp2p;
  • Highly scalable;
  • Rust-based primary implementation for speed and reliability Javascript secondary implementation for development
  • Wasm WebAssembly interpreter, written in Rust.


Not all blockchains are suitable for all networks. With Substrate, however, you can combine features to fit the needs of each project:

  • Ink Smart Contract
  • Status and transactions are encrypted.
  • Limited asynchronous call options.
  • Locked account level.
  • Administrative tools and methods such as stakeholder referendums, approval voting, and qualified abstentions.

Do Substrate and Polkadot necessarily need to go together?

If you follow Polkadot, you will see the term “Substrate” appear very often. This makes many people mistakenly believe that Substrate belongs to Polkadot, and that all Substrate projects are parts of Polkadot. However, this is not correct. There are many independent chains built with Substrate, and not all projects built on Substrate are in the Polkadot ecosystem.

Projects built on Substrate

Currently, there are more than 170 projects built on Substrate, including some prominent names such as: Kusama, Chain X, Chain Link, etc. With the rapid growth in the number of projects, Substrate has shown that it's a fairly simple and easy-to-use toolkit, which makes it a popular choice for blockchain developers.

BHO Network's BHO Chain is also built on the Substrate foundation, with proven stability, performance, and security. With NPoS consensus protocol instead of conventional PoW, BHO Chain can effectively save energy, and be environmentally friendly. In addition, BHO Chain has many other benefits, such as the Cross-chain Bridge feature that allows the transfer of crypto assets, tokens or data from one blockchain to another; and optimization for DeFi and NFT.


With the development of projects in the Polkadot ecosystem, Substrate is an essential technology in the future Web 3.0 vision. Substrate provides developers with a set of tools to create and develop blockchain quickly and simply. Substrate helps projects easily access and develop on the Polkadot ecosystem in particular and other ecosystems in general, including the ecosystem of the upcoming BHO Network.

We hope you have a good overview of Substrate. Follow BHO Network's channels for instant updates on market news and projects!
