Unless you’ve been living under a rock, you’re probably aware of Blockchain and its potential for reforming the tech world. This technology has helped mitigate the traditional challenges various industries face over the years, allowing them to seize better opportunities.
Blockchain technology is at the heart of Bitcoin, the world’s most popular cryptocurrency. With the popularity of Bitcoin, Blockchain has received a lot of attention. People are now using Blockchain in non-cryptocurrency applications as well as Works.
As a result, this article will go over Building A Blockchain In.NET Core. Learn how to create blockchain technology in ASP.NET.
What is Blockchain?
Blockchain is a database. What is a database? A database is a well-organized collection of information. Alternatively, a data structure that stores data. As a result, Blockchain is merely a data structure that stores data. As the name suggests, there will be a chain of blocks.
Blocks Chain:
The basic blockchain architecture diagram is shown below.
This basic Blockchain is comprised of a linked list of blocks. The following are the properties of each block.
- Index
- Timestamp
- Previous Hash
- Hash
- Data
The first block is a special block called the genesis block. The genesis block is the only one with no preceding blocks and no data.
Implementation:
We will add two classes to this data structure: Block and Blockchain.
Block:
Blockchain:
After those two classes, we can create an instance of the new Blockchain.
And we can add blocks to it.
The code is shown below.
The Blockchain data will be serialized into JSON and output in the console.
Validation
Data security is one of the advantages of using Blockchain. Data security means tampering with old data, and changing the method of securing new data is prevented by both cryptographic and non-centralized storage. However, Blockchain technology is simply a data structure in which data can be easily changed in this manner.
As a result, we need a method to validate the data. This is why I added an IsValid method to the code.
The IsValid method will check two things.
- Check the previous block’s hash to see if it has been changed and recalculated.
- Then, before and after data tampering, we call IsValid to see if there are any data issues.
The Validation result will remain false because the validation examines not only the current block but also the link to the previous block.
What if an attacker recalculates the hashes of the current and subsequent blocks?
The verification is successful after all of the Blocks have been recalculated. Because Blockchain is a decentralized system, this is only sent to one node. Tampering with one node is possible, but tampering with all nodes in the system is impossible.
What exactly is ASP.NET?
ASP.NET is an open-source server-side web application framework. It was created by Microsoft at the turn of the century and ran on Windows. ASP.NET allows developers to create dynamic content-driven websites, web applications, and Denver web design services. It creates simple, fast, and scalable solutions based on HTML5, CSS, and JavaScript.
Dot Net technology is still widely used in business. Because Share IT works with many enterprise-level businesses, we consider ASP dot NET our golden goose.
.NET is a developer platform that includes tools, programming languages, and libraries for various applications.
The base platform contains components that apply to all types of apps. ASP dot NET and other frameworks extend .NET with components for developing specific types of apps.
There are the following features of the.NET platform:
- Base libraries for working with strings, dates, files/IO, and other data types in the C#, F#, and Visual Basic programming languages
- Editors and tools for Windows, Linux, macOS, and Docker.
How to develop blockchain technology in ASP.NET:
Yes, if you keep the decentralized concept in mind when writing your code. A Blockchain does not require the use of a specific language.
However, to contribute to the community currently developing blockchain-based applications, coding platforms of top cryptocurrencies such as Solidity, which is used in Ethereum smart contracts, are recommended.
This is not to say that the Blockchain is limited to those platforms. You could create something amazing, so use the core concepts while experimenting with the existing stuff.
How can I implement blockchain technology in asp.net:
Yes, Blockchain is a concept that can be implemented with ASP.NET.

This is not to say that the Blockchain is limited to those platforms. You could create something amazing, so use the core concepts while experimenting with the existing stuff.
Is ASP.NET going away?
It shouldn’t be dying; now is the best time to be a NET developer or learn. NET. Reasons for this include:
ASP.NET Core – runs on Windows, Linux, and OSX. Xamarin – write code once, reuse it, and deploy most of it to native mobile for iOS, Android, and Windows devices.
- NET Core is extremely fast. Recent benchmarks show that it outperforms many other languages, including NodeJS. It’s open source, and Microsoft is letting the community drive a lot of the innovation, so we’re seeing more features that we want rather than what Microsoft thinks we want.
- C# is a lovely programming language.
Conclusion:
Blockchain is a new name in technology but will not be forgotten. Even in its early stages, the technology has gained enormous popularity, beginning with the first application of cryptocurrencies. With each passing day, more application areas are discovered and tested. Once the technology is adopted and accepted globally, it will transform our daily lives.
A blockchain is a chain of blocks. It makes use of cryptography to ensure data integrity. Visual Studio 2017 can be used to open and run the sample code.
