Blockchain Technology is the next revolution in the digital sphere. A blockchain is a shared distributed database or ledger between computer network nodes, and it serves as an electronic database for storing data in digital form.  The novelty of a blockchain is that it fosters confidence without the necessity for reliable third data. Blockchain testing assists to deliver a high-quality product and meeting specific requirements.

In a blockchain, data is gathered in groups called blocks that include data sets. Blocks have specific storage capabilities; filling of which, seals and connects it to the block to create the data chain.

When decentralized, this creates an irreversible chronology of data by design. On the completion of input of a block, it is added to the timeline, and receives an accurate time stamp.

Use Cases of Blockchain Tech Across Various Industries

Decentralized security and trust are made possible by technology in several ways. This has led to several industries introducing this modern technology into their processes and operations.

Here are some use cases across various industries.

Banking and Finance

Banking is one sector that could stand to gain the most from incorporating blockchain into its corporate processes. Through this technology, users can make transactions and deposits at any time.

Customers can make transactions using blockchain in as little as 10 minutes. Banks can now safely and swiftly transfer money across organizations.


Healthcare providers may use blockchain to safely preserve their patients’ medical records. The ability to write a medical record onto the blockchain once we create and sign, assures patients that the alteration of records is not possible. These sensitive encrypted health records contain a secret key so that only authorized people can access them, maintaining their privacy.

Real Estate

We can use Blockchain technology for maintaining and signing property records which can be highly challenging for buyers and sellers today. Blockchain stores property records accurately and permanently in blocks with transparency and a clear description of timelines and ownership. Owing to its framework and operational policies requiring authentication/validation at every stage, it also reduces the possibility of fraudulent transactions.

Supply Chains

Businesses and consumers expect brands to ensure the authenticity of their products, while supply chain actors want improved visibility and responsible sourcing to reduce conflicts. Blockchain-based supply chain solutions assist executives in using data to manage current disruptions and fortify resilience for the future.

One-up/one-down visibility can be a constraint for supply chain networks. Smart contracts operate on the Blockchain supply chain solutions, which allows business owners to track and maintain operations and ensure visibility in real-time.


Blockchain facilitates a contemporary voting system. As demonstrated in the West Virginia midterm elections in November 2018, voting using the technology can end election fraud and increase voter turnout.

Tampering with votes would be next to impossible. Blockchain technology will also uphold electoral openness while lowering the number of people required to carry out an election and giving officials access to results almost immediately. As a result, there would be no need for recounts and no legitimate reason to be concerned that election fraud would occur. Blockchain is also ideal for preventing fake votes and fraudulent voter registration.

Testing Blockchain Applications

Testing a blockchain is essential to ensure that any errors in all ledgers are removed. This eventually shields a company from the drawbacks of a poorly functioning app. Implementing testing enables verification of the many parties the blockchain system depends on for operation and verification that the built ecosystem is operating as intended.

Testing will help lower the risk of introducing error-free new apps and ensure a seamless installation. Testing assures the delivery of high-quality goods and improves consumer experiences.

It is crucial in the case of public blockchain as real money is at stake. A single error in smart contracts might result in significant financial losses.

In a nutshell, testing blockchain apps involves inspection of every aspect of the chain from the ground up. This includes the chain itself and all the associated ledgers.

Challenges of Testing Next-Gen Blockchain Apps & Ways to Overcome

Blockchain testing is irreplaceable and lacks technical, functional, and legal competence. It encounters many problems due to developers’ weak conceptualisation, standardization, and abstraction skills.

Blockchain end-to-end testing necessitates a heterogeneous tool set for testing applications, without which the testing can be inadequate. Additionally, evaluating blockchain may be costly and time-consuming. Currently, very limited advanced tools or strategies are available for testing. Because there are so many different frameworks like Ethereum, Hyperledger, etc., it might be challenging to test them all.

Failure to do performance and load testing provides little to no insight into how the Blockchain application operates in real-world settings and under specific workloads and network circumstances.

More effort should be applied on teaching and training QA specialists about blockchain testing to get the most significant outcomes. Testing teams must improvise on testing methods and strategies to meet the requirements for the testing. Performance and load testing can help testers understand the capacity of the app under peak conditions. This helps in improving the performance of the app. Ensuring the blockchain is free of errors also helps enhance user experience and platform reliability. An experienced team with an aggregate knowledge of this technology can guarantee a thorough testing process across industries.

Experienced QA Testing Teams for Enhanced Blockchain Testing

Although blockchain technology is new to the digital sphere, an experienced testing team like QAonCloud can drastically enhance the quality of products through software testing and accuracy with their robust knowledge and subject matter expertise on the advanced technology. Additionally, QAonCloud testing teams can perform high-quality testing with suitable testing tools. Our testing solutions can be highly beneficial in rendering a secure and fail-proof technology for businesses across industries.
