7. Conclusion

1. Ethereum

The main features: Ethereum is a public open-source platform based on the Proof of Work idea. It gives developers a set of tools to use in order to create blockchain-based solutions in the Ethereum Virtual Machine environment. Ethereum includes its own programming language, Solidity, as well as its own cryptocurrency, Ether, which is used to execute transactions and run programs on the Ethereum network. The market value of one ETH was $2,236 at the end of May 2021, according to the Ethereum Price, making Ether the second most valuable cryptocurrency on the market behind Bitcoin.

Strong and weak points: Its high level of security owing to decentralization, low downtime, adaptability, and large community. Of course, there are flaws in the system. For example, as compared to other platforms, there are lengthy processing times and greater transaction prices, as well as scaling concerns. It’s worth mentioning, however, that the Ethereum team is now troubleshooting. In 2021, for example, the platform teamed up with Polygon, a company that wants to build Ethereum-compatible blockchain networks. In addition, Ethereum is undergoing a redesign known as Ethereum 2.0, which will work on the Proof of Stake (PoS) principle to improve security and scalability while also making Ethereum more accessible.

Use cases: The emergence of DeFi in 2020 and NFT in 2021, both of which are closely tied to Ethereum, has increased demand for the network. The number of Ethereum-based projects available is astounding. Aside from banking, the platform is used to develop voting systems, secure medical data storage, games, and social networks, among other things. The number of effective Ethereum use cases is growing, and Ethereum will be one of the most promising blockchain development platforms in the coming year’s thanks to continual developments.

2. Hyperledger Fabric

The main features: Hyperledger Fabric is a cross-industry blockchain network that lets developers use plug-and-play components to build blockchain-based solutions. The modular architecture is to thank for this. The platform was designed for usage by industrial enterprises and is permissioned, meaning that only authorized users have access to data. Hyperledger Fabric also has ‘chain codes,’ which are smart contracts.

Strong and weak points: Hyperledger Fabric combines the advantages of blockchain technology with improved security and privacy for sensitive data. It provides good performance and scalability, as well as the ability to set up a clear identity management system to regulate who joins the network. This is an example of a blockchain that can be used by businesses that aren’t involved in cryptocurrency projects.

The platform is always becoming better. Hyperledger Fabric 2.0, for example, was launched in January 2020. The update improves data privacy while also ensuring decentralized smart contract management.

Hyperledger Fabric, on the other hand, is not ideal for people seeking transparency. There are minimal use cases for this platform because the market is mostly focused on public blockchains.

Use cases: Hyperledger Fabric allows for private transactions and confidential contracts, making it appropriate for financial institutions that value privacy and security. Other enterprises, including healthcare, government, and supply chain corporations, can use the platform to build their own private blockchain network. HP, Amazon, Visa, Walmart, and more companies have already adopted this technology.

Despite fierce competition in the market, Hyperledger Fabric is one of the most popular solutions for building enterprise blockchains. According to IDC, enterprise blockchain spending in Europe has increased by 60% in the last year, and we can expect continued demand for this blockchain development platform.

3. Polkadot

The main features: Polkadot is a technology that allows for the creation of a multi-blockchain network with completely decentralized information exchange. Developers can establish new blockchains and connect existing ones in this ecosystem. You may use permission data from a private blockchain in a public blockchain thanks to Polkadot’s unique architecture, which supports para chains. It has a good potential of becoming one of the top blockchain development platforms in the coming years because it addresses the issues of blockchain scalability and interoperability.

Strong and weak points: Polkadot offers various advantages to both developers and consumers of blockchain technology. First, the network enables the processing and transmission of data between public and private blockchains in a rapid and safe manner. The platform is really scalable and useful. Second, it provides new potential for decentralized application developers. Polkadot, for example, allows individual blockchains to rely on common security characteristics by offering a single foundation for creating protocols. Polkadot is viewed by many blockchain specialists as a game-changing solution that makes the concept of a unified blockchain network more realistic than before.

Polkadot is a relatively young project, hence there are few use cases to fully understand the technology’s effectiveness. Some criticize it for its lack of decentralization, which is attributed to its reliance on its own DOT currency.

Use cases: Polkadot focuses exclusively on crypto projects, such as DeFi and NFTs. It teamed up with the Chainlink initiative in 2020 to recruit DeFi app developers. Transaction chains, IoT chains, oracle chains, identification chains, data distribution chains, and other types of chains can all be built on the platform. The platform’s popularity is growing, and we’re optimistic that new exciting initiatives in the Polkadot ecosystem are on the way.

4. Solana

The main features: Solana differs from other platforms in a number of ways. There are no sidechains or para chains on this first-level blockchain. The platform is decentralized and open-source. It has its own cryptocurrency, which is known as SOL. Nodes on the Solana blockchain are compensated for processing SOL transactions, and unlike many other blockchains, it does not require a minimum quantity of money to set up a node. Solana employs a new cryptic technique known as Proof of History (PoH). It enables increased scalability and transaction processing speed. Solana’s current throughput, according to representatives from the Solana Foundation, is 60,000 transactions per second.

Strong and weak points: The key benefits of Solana are not limited to transaction speed and cost. The platform also offers exceptional scalability and project compatibility. It also provides a good user experience, which is lacking in many decentralized initiatives.

Because Solana is a relatively new blockchain platform, it has yet to receive significant adoption, and many projects are still in the works. Many functionalities are in test mode, which implies there is a chance of a system crash. Furthermore, some developers argue that the blockchain is not sufficiently decentralized. Despite this, Solana has a lot of potential and numerous advantages over other cryptocurrencies like Ethereum.

Use cases: Although Solana has been on the market for some time, rising interest in NFTs resulted in a significant boom in 2021. Because mining non-fungible tokens on Solana is cheaper and faster than on Ethereum, many users and projects interested in non-fungible tokens have chosen it for further development. There are many of DeFi projects based on Solana, such as wallets, DEXs, and stablecoins. According to various sources, Solana’s ecosystem currently includes approximately 200 enterprises.

In addition, the network is still evolving. The Solana Foundation was established in 2020 to aid in the development of the environment. Solana Labs donated 167 million SOL coins to the foundation in exchange for this. In addition, Solana developers established a cross-chain bridge with Ethereum in October 2020, allowing for asset transfers between the two blockchains.

5. Cardano

The main features: Cardano is a proof-of-stake blockchain platform that is open-source. It has a multi-layered architecture and its own coin, ADA. Cardano is based on the Proof-of-Stake principle, which examines the amount of bitcoin in circulation. Smart contract functionality is available on the platform. The most appealing aspect of Cardano is its decentralized nature. The platform achieved 100 percent decentralization in 2021, and the network now has over 1500 validator pools.

Strong and weak points: Cardano is a powerful and scalable cryptocurrency. Its transactions are speedier and less expensive than the Ethereum network. The ability to make passive income by staking ADA coins is another feature that appeals to users. The platform places a strong emphasis on security. Ouroboros, a Cardano protocol, contains mathematical proof of the system’s permanence even if nodes are offline temporarily owing to a computer failure or power outage, for example. Because of its high decentralization, the system is exceptionally stable.

Cardano is characterized as an “academic blockchain” because it was created after much research and testing. On the one hand, this increases network trust, but on the other hand, it slows down the platform’s development. Much of the criticism stems from this, as the market is very competitive, and the speed with which new ideas arise is critical.

Use cases: Smart contracts, decentralized applications, and sidechains are the main areas of Cardano’s attention. The network also supports NFTs, propelling it to the top of 2021’s blockchains. Cardano is now being used to construct DEXs, NFT marketplaces, stable coins, lending protocols, and other applications.

The Cardano team has a well-defined strategy for upgrading the technologies they employ. The platform is likely to get a number of changes in the near future that will make it an even more appealing option for the creation of blockchain enterprises.

The post Top 5 Blockchain Development Platforms for 2022 appeared first on DX Business Group Software Solutions - Blog.

Before proceeding with a project, the first and foremost thing we must do is clearly define ideas and product orientation. If the initial idea is poorly tested or the core values are not seen through, the project will inevitably have problems with the wrong values; From there, hinder the later stages and sometimes the final result. To avoid this situation, we should use the Proof of Concept (or POC) method for software development – a term that is familiar but not less important. Although Proof of Concept does not produce a product, it does provide certain visions and assessments of the project’s advantages and disadvantages; thus, we can come up with clear solutions that the team can go in the right direction, with the right spirit and product style.

In the following topic on Proof of Concept, DX Business Group Software solutions will show you the importance of Proof of Concept and outline 5 critical factors to success.

What is a proof of concept in software development?

A proof of concept in the context of custom software development comes to be the validation of a functional or non-functional aspect of an information system or part of it, either by the technical area or by the user area.

We could say, for example, that acceptance tests are a specific type of proof of concept.

Proof of Concept Example

During the establishment and implementation of the project, Proof of Concept was highly appreciated, playing an indispensable role. Thanks to the Proof of Concept Guideline, Project Managers can see suspicious factors and potential risks that can hinder the success of the project. Proof of Concept helps both the client and the developer team to agree on the value and general direction of the project; On the other hand, it also helps developers easily identify ways to carry out the project to achieve the highest efficiency.

At DX Business Group, we will take an example of good Proof of Concept, with thorough steps we take to create a successful Proof of Concept for our software product:

Step 1: Define customer requirements

The first and also the most important step, is clearly defining the requirements of the client. Determining the requirements of the client to help us understand the feasibility of the project, understand the nature, and at the same time understand the capabilities of our human resources, thereby identifying and selecting personnel suitability to join the project.

Step 2: Action Planning

Next, the Developer team will analyze and consider the specific project requirements, thereby providing specific scenarios, timeline,s, and guidelines, as well as selecting the appropriate staff to pursue the project. Each stage of implementation, each step is streamlined with the client’s time and the Developers’s team.

Step 3: Implementation

Based on the established Action Plan, the project will be conducted in a 6-stage loop to ensure effectiveness.

The implementation will start a new process of analyzing customer requirements once more thoroughly to proceed to the Design step. Then, the product will be formed and developed with Development, preliminary completion and to the Testing step. In this step, Tester will carefully check and find out the wrong points of the product, so that the Developers can see and correct it more appropriately. By the fifth stage, the product is nearly completed and deployed soon, the Developers will conduct product testing operations with customers and move to the 6th stage – Review, listen to feedback from customers and edit to please customers, and make products more complete.

Step 4: Delivery

The product is now completely complete in accordance with the requirements and spirit of customers. We carry out the delivery of the product, and at the same time provide general information on how to use it, along with some necessary information to ensure smoothness during the operation of the product.

Therefore, 

It can be considered as a useful tool in the development process. However, it is convenient to adequately manage your expectations and objectives in the current context of the project and the information system, that is, what is intended to validate? What are the minimum thresholds required? Does the validation meet qualitative, quantitative or both criteria? What are the consequences of not exceeding them? Are the limits well calibrated concerning the effects on the Current status of the project and the current phase of its life cycle? Who will participate in the proofs of a concept and know in advance what aspects are not going to have the expected behavior?

Test levels

In a formal testing process, test levels are often very easily confused with test types, and although they are intimately related, they have different connotations in the process. To understand a little more, let’s start from the fact that the tests can be executed at any point of the software development process, and this is where the test levels allow us to understand the different aspects or stages where specific tests can be executed. Because of the above, it is common for some people to refer to the levels of evidence or try to classify them as developer tests, functional tests, and end-user tests.

Nevertheless, the appropriate terminology to apply to the different levels corresponds to the following four (4) classifications that are: unit tests, integration tests, system tests and acceptance tests. In each of these test levels, different types of tests may be executed, such as functional, non-functional, architectural tests and the change of the products associated.

Here is a brief description of each level of evidence:

1. Unit or Component Tests: These types of tests are typically executed by the development team. They consist of the execution of activities that allow the developer to verify that the unitary components are coded under robust conditions, that is, supporting the entry of erroneous or unexpected data and demonstrating, thus the ability to deal with errors in a controlled manner. Additionally, the tests on unitary components, usually denominated tests of modules or tests of classes, being the convention defined by the programming language, the one that influences the term to use. Finally, it is essential that all the functionality of each unit component be covered by at least two test cases, which should focus on testing at least one positive and one contrary feature
2. Integration tests: It is as well executed by the development team and consists of checking those elements of the software that interact with each other, work correctly
3. System Tests: This type of test should be executed ideally by a test team outside the development team, a good practice in this point corresponds to the outsourcing of this responsibility. The obligation of this equipment consists in the execution of test activities where it must be verified that the total functionality of a system was implemented according to the specification documents defined in the project. The test cases to be designed in this level of tests must cover the functional and non-functional aspects of the system. For the design of test cases at this level, the team must use deliverable test bases such as initial requirements, use cases, user histories, designs, technical and end-user manuals, etc…
4. Acceptance Tests: Independently of the fact that the testing process has been outsourced and that the firm responsible for these activities has issued a quality certificate on the system under test. It is essential that the client appoint personnel to be part of the business processes for the execution of acceptance tests, it is even recommended that the end users participating in this process be independent of the personnel that supported the development process. When the acceptance tests are executed in facilities or environments provided by the developer, they are called Alpha tests, when they are performed from the clients’ infrastructure, they are called Beta tests. In cases where the acceptance tests of the product have been executed in the supplier’s environment.

On the other hand, the security of a system or application does not depend on the use of SSL protocols, firewalls or compliance with an ISO 27000 standard. The form of security tests (penetration testing) at the end of the software development cycle is not enough either. Security is a factor that must be taken into account in each phase of development since the production of software is a process in which it is necessary to identify and correct vulnerabilities continuously.

The key, therefore, is in the following question;

Are we building secure software?

At our site we propose the following tools that help develop secure software:

Checkmarx, which is a source code tool used for security analysis, can be integrated with the most common SW development environments (Eclipse, MS-Visual Studio, Jira, Jenkins …) that will alert programmers to the vulnerabilities they enter in their code.

Blackduck, a tool for analyzing the security, licensing, and operation of third-party open-source libraries used in the developments themselves. Also integrable with the usual development environments.

In contrast, a security analysis tool for the running application based on IAST (Interactive Application Security Testing), or what are the same gray box tests.

We help our clients in the implementation of the Secure SW Life Cycle, an essential practice:

1. Analyzing the situation of SW processes and the SW development tools used.
2. Propose the most appropriate security tools in each case.
3. Performing concept tests for the proposed tools and their use in customer processes validity.
4. Forming and supporting development engineers.

From a practical point of view, the number of possibilities to exhaustively test a system is merely unmanageable; it is then necessary to use adequate techniques to maximize the number of essential failures found with the allocated resources. Each method used to detect defects leaves a residue of more subtle abnormalities against which this technique is ineffective.

The software test implies, therefore, the application of appropriate techniques and tools in the framework of a well-defined process, determined by the type of software development projects that are addressed.
