It’s difficult to create a blockchain from scratch. In light of this, it’s critical to offer a secure platform that users and apps can rely on; to do this, you need to have the appropriate technologies, such as distributed network communication and sophisticated cryptography. Additionally, the ecosystem needs to handle the problems with current blockchains and how those flaws affect that particular blockchain protocol.
Before creating a blockchain, factors like as governance, upgradeability, interoperability, and even the blockchain trilemma—giving up one “aspect” of decentralization, security, and scalability to accommodate the other two—should be taken into account. It would also be beneficial if you thought about the appropriate use case for your blockchain and the motivation for its creation. To overcome these issues, the substrate is an ideal choice for creating a unique blockchain that is tailored for particular use cases. It is an excellent fit for cutting-edge and complex blockchains and a terrific choice for programmers who wish to create a blockchain that is easily upgradable over time, customisable, and interoperable.
You can create use cases that are unique to your requirements and get around the difficulties of reusing a general-purpose blockchain provided by smart contracts by employing substrate. For instance, developers do not have to put up with drawbacks like inheriting a blockchain’s unique architecture or the laborious upgradability method.
After learning the fundamentals of substrate, you may be wondering if it can help you create a blockchain with definite use cases that targets your specific sector. So, let’s use this article to better grasp the substrate framework’s application cases.
What’s the Substrate?
It is essential to fully comprehend substrate before proceeding to the substrate use cases. The Substrate is akin to a Software Development Kit (SDK), giving programmers access to the essential elements of every blockchain so they can design a protocol that is both comparable to and unique from other blockchains.
Common blockchain components like storage, consensus, and cryptography account for the similarities. You can combine or alter these common traits to suit the goals of your project using the framework that the Substrate offers. It makes it possible for a chain to grow far faster than it could for anyone else.
As a blockchain foundation, the Substrate lets users create chains that are quicker, easier, less expensive, and safer. It’s
- Flexible: Substrate is meant to be a modular and adaptable toolkit that lets you build a chain out of completely diverse parts.
- Open: The architecture and substrate toolkit are made available to users under an open-source license.
- Interoperable: Blockchains created using the Substrate can communicate with other blockchains created in a comparable manner. Additionally, it can be linked to another blockchain using bridges or Polkadot parachains if necessary.
- Future-proof: The Substrate can be upgraded, disassembled, and modified.
Applications of the substrate framework
Use cases for substrate frameworks differ. By offering the ideal setting for the development of blockchain-based applications, it makes developers’ jobs easier. The most well-known substrate application cases are as follows:
The substrate is a blockchain framework that allows for the creation of personalized, fully autonomous blockchains. It is the quickest and least labor-intensive method of launching a blockchain because it doesn’t require any external technology to operate. The essential elements, such as networking, data layer, transaction queue, consensus, and more, are taken care of for the developer by substrate. Furthermore, you can use a pallet that meets your needs to upgrade your blockchain project over time.
The substrate is modular and expandable. A standard blockchain architecture may restrict you in some areas of customization, depending on the use case. A substrate is more adaptable in this sense, though. It gives you the freedom to decide at various points in your blockchain development process between ease of development and technical freedom. You can create new blocks or use custom ones. You are allowed to either develop a smart contract with your own functionality or not create one at all. With substrate, you can alter the smart contracts through the on-chain upgrade process, in contrast to Ethereum smart contracts, which are unchangeable once they are deployed.
When linked to the parachain, blockchains constructed on a substrate can take advantage of its security features and other advantages while remaining autonomous or interoperable.
The development of parachains is a significant substrate application case. In the Polkadot ecosystem, which operates in parallel to the relay chain and takes advantage of its advantages—such as shared security or payment settlements—parachains play a crucial role. Parachains’ architecture protects user data privacy while enabling quicker transactions at a reduced cost.
Through the substrate, anyone can install a parachain that is specially designed for a given use case. The substrate makes the procedure easier overall, even though it can be constructed using different software options and tools.
Substrate is a superior choice when constructing parachains, as evidenced by the following characteristics:
WASM runtime engine: excellent performance and forkless upgrades are guaranteed by the substrate’s WASM compatibility.
consists of modules for development.
The Byzantine Fault The algorithm for tolerance consensus: When some nodes are broken or disabled, the BFT consensus mechanism makes sure that the parachain or blockchain continues to function.
It can communicate with all cloud nodes and implement a browser node with ease.
With substrate assistance, you can immediately deploy the projects you’ve built to Polkadot and begin executing.
Cross-platform database storage abstraction is provided by Substrate.
Parachain and substrate are hence complementary. The substrate is your best bet if you want to construct a parachain on Polkadot. It is a straightforward yet helpful tool that can help you build a strong, dynamic, and extremely functional parachain. Furthermore, a solo chain can be joined to a parachain or transformed into a parachain by the substrate.
Pallets Pallets are domain-specific runtime modules that enable us to have a modular design. The pallets are like discrete logic parts that define your blockchain’s functionality. It is possible to add more than one pallet to our runtime, and each pallet serves a specific purpose in meeting the blockchain’s business requirements.
Numerous pre-built pallets are typically available on the substrate developer site. If it doesn’t meet your needs, though, you can create a custom pallet for a substrate runtime by using the macros in the FRAME programming environment.
The substrate node template has a FRAME-based runtime. FRAME is a programming library that composes modules or pallets to make it easier to construct substrate runtime. With Substrate, you may build an application-specific pallet that can be used to assess how well your blockchain or application works. For example, you can use substrate to build a pallet for your application if you wish to use the zero-knowledge proof feature.
Users must use a cross-chain bridge, which is a collection of correctly written code that includes smart contracts, to move tokens or other digital assets, smart contract events or instructions, or even data across different blockchains. A cross-chain bridge makes guarantee that two chains with dissimilar rules, regulations, governance structures, etc., can nevertheless collaborate securely.
Constructing bridges across chains is a noteworthy application of substrates. To take advantage of all the advantages of relay chain and parachain, you may use substrate to create a cross-chain bridge that connects your blockchain application to both the Polkadot network and any other blockchain network. It can provide your network with genuine interoperability, enabling users to move assets, data, and more between chains. This might raise the asset’s worth.
The substrate framework provides a comprehensive set of parts and building blocks for the development of bridges. However, if the pre-built pallets don’t meet the specifications of your application, you can also use the substrate to construct a bridge that meets your needs.
In order to more readily take advantage of shared security and connectivity, parathreads extend the idea of parachains. Polkadot offers the opportunity to become a parachain if their application requires high throughput, and is currently more accessible to projects who might not have the resources to obtain a specialized parachain slot. Any development team can use parathreads to bootstrap their application and access the relay chain.
Parathreads are a good fit for the following three uses:
- Applications that require a Polkadot on-ramp
- Applications that fear losing their parachain slots
- Applications with a higher read-to-write ratio
Anyone can use parathread to link their application to Polkadot’s relay chain and take advantage of its features, such as interoperability. Substance can assist you in building your parathread.
The Polkadot network center chain that is constructed using the substrate is known as the relay chain. It is in charge of consensus, cross-chain interoperability, and network security. Every parachain is linked to the relay chain and utilizes its advantages.
You can initiate your Polkadot-style relay chain using substrate. Substance lessons with a variety of templates are available for everyone to access. If the current templates aren’t adaptable enough for your use case, you can build one yourself or get in touch with a substrate development business that can help you with the process.
