Substrate is a concept that is mentioned a lot in the Polkadot ecosystem, so let’s find out what substrate is? What does it have to do with Polkadot in the article below

What is Substrate?

Substrate was created to address the shortcomings of previous networks. These developers discovered that they were recreating many of the same features in the early days of Bitcoin and Ethereum, but with different limitations in terms of scale, governance, forks, interoperability, and upgradeability.

As a result, substrate was created with the goal of removing the need for developers to recreate the fundamentals when creating and optimizing blockchain.

Substrate is understood as a Software Development Kit (SDK) that supports building a separate blockchain based on a library with custom or pre-made components.

Some highlights of Substrate

  • Flexible: Substrate is a fully modular blockchain framework, developers instead of building blockchains that are bound to an existing module, they can modify the module to fit the project.
  • Interoperable: Substrate-based blockchain networks can choose to operate as a solo chain, a single chain with bridges, or integrate as a parachain. Integration as a parachain allows independent Substrate-based blockchains to gain interoperability with other independent blockchains.
  • Open source: Substrate uses familiar open source protocols such as Libp2p and JSON-RPC, developers are not tied to a specific design, In addition to the available tools, the project developer You can also use tools created by people in the Substrate developer community. The combination of open source, customizable architecture, rich tools, and a strong community make Substrate the most open technology for building blockchain networks.
  • Future-Proof: Blockchain technology is developing at a rapid pace and has promoted many other new technologies such as Zero Knowledge, Consensus Mechanisms, Cryptographic Libraries… Substrate allows blockchain to synchronize with new technology when it appears.

Relation between Substrate and Polkadot

All Substrate-based blockchains are seamlessly compatible with Polkadot, providing access to a rich, interoperable ecosystem of parachains, applications, and resources. There are currently about 185 projects being built on Polkadot’s substrate at the time of writing. The construction on Polkadot’s substrate has some notable points as follows:

  • Polkadot is a layer-0 protocol and mutichain network that lays the foundation for the future of Web3. Substrate is a major blockchain software development tool used by developers to create the parachains that make up the Polkadot network.
  • Substrate allows developers to build specialized blockchains for any use case and is used by tech company Parity Technologies to create Polkadot itself, demonstrating its high level of performance, flexibility, and robustness. .
  • Substrate can be used to build any type of blockchain, not just Polkadot parachains. Connecting to Polkadot offers a multitude of benefits, including built-in security, cross-chain interoperability, and access to Polkadot’s growing ecosystem of platforms, applications, and end-users.
  • Building a custom blockchain with Substrate offers more freedom, flexibility, and optimization than building on a general purpose smart contract blockchain.
  • Essentially, Substrate is an SDK with which you can build parachains, and Polkadot is a means of securing blockchains and allowing them to communicate with each other. Although they work together, Polkadot and Substrate are not dependent on each other. Polkadot parachains can be built and maintained without touching Substrate, and blockchains built with Substrate do not need to be connected to Polkadot. Substrate-based chains can exist as ‘solo-chains’ on a standalone basis.


Substrate provides developers with the tools they need to quickly scale blockchain without having to deal with too much. Substrate helps projects easily access and create strong development on the Polkadot ecosystem in particular, and other ecosystems in general, due to the rapid development of the Polkadot ecosystem.
