In our quest to meet the needs of users who seek to store value in a crypto-asset that is less volatile and less inflation sensitive, we established close relationships and partnerships with several technology companies to ensure we fulfilled our mission. Fortunately, through these strategic partnerships, we were able to come up with our gold and blockchain-based products that harnessed the power and stability of gold and integrated them with the technological security of the blockchain network. We again took the initiative to create multiple layers of proprietary technologies, protocols, and secure processes to ensure the safety of our client’s assets. We value security and have made it our top-most priority. Therefore, we have invested in a range of over and above security features aimed at protecting our client’s privacy along with our products. One of the security features that we will talk about today is our multi-tiered, multi-firewall architecture.  

What exactly is Multi-Tiered, Multi-Firewall Architecture?

Multi-tiered, multi-firewall architecture is a term that is mostly used in software engineering to refer to a client-server architecture that has the application processing, data management, and presentation functions separated physically and logically. This kind of multi-tier architecture is also referred to as the n-tier architecture. The “n” in the n-tier architecture refers to any number from 1 and up. For example, an n-tier architecture with 1 tier is referred to as a single-tier architecture. The tiers can go up to 5 or more, however, the most common and popular multi-tier architecture being used is the three-tier architecture.

The underlying design behind the multi-tier, multi-firewall architecture is that different functions are separately hosted on different or several machines ensuring that services are provided without resources being shared. Basically put, this means that by using the multi-tiered, multi-firewall architecture, we end up providing top-notch services to our clients. And as research shows, great products are usually built on multi-tier architecture. Separating these components into different and separate tiers increases the scalability and maintenance of each function. This enables new technologies to be applied to each tier easily without necessarily having to redesign the whole system.

To get a proper understanding of the multi-tier, multi-firewall architecture, we are going to look at the three-tier architecture that happens to be the most popular n-tier architecture in use today. In a three-tier architecture, the application is divided into three different tiers, namely:

  • Presentation Tier
  • Logic Tier
  • Data Tier

Each tier represents a separate function and component of the overall application that can be separated and isolated from the overall application and the other components. Furthermore, the three-tier application typically stores sensitive information in the logic tier which ensures that this information remains isolated from the presentation tier.

Functions of Each Tier

  • Presentation Tier

This tier can also be referred to as the user interface. This is what the user sees and interacts with on the surface level. Its main function is to translate tasks and results and display them in a manner that the user can understand. It also acts as an intermediary between the user and the logic tier by passing along the user’s different actions and requests to the logic tier.

  • Logic Tier

This tier goes by different names such as the business logic, data access tier, or the middle tier. This tier controls the applications process by carrying out detailed processing such as processing commands, performing calculations, evaluating and making logical decisions, and moving data between the two other tiers. It basically thinks and assesses what is allowed by the application and what is possible, along with other decisions.   

  • Data Tier

This tier acts as a database server by storing all the data used in the application. Data can be securely stored and safely retrieved from this tier and passed back to the logic tier for processing and eventually to the user. A huge volume of data can be stored in this tier and can be accessed in a matter of seconds. It also improves the entire application’s performance and scalability.

Who Developed the Multi-tier, Multi-firewall Architecture?

The multi-tier architecture was developed by Professor John J. Donovan under OEC (Open Environment Corporation), a tools company that he founded in 1991 in Cambridge, Massachusetts. Donovan identified that the technological environment was essentially changing at a rapid rate and needed to find a way to make applications more user-friendly and accessible for non-technical users. In his quest to do so, he pioneered the three-tier architecture that found major acceptance and success with customers and investors alike.

Benefits of This Technology

The following are some of the benefits of using this technology. They include:

  1. Enhanced Security: Each tier can be secured separately using different methods.
  2. Separate Management: You can modify and add to each tier separately without interfering with the functioning of the other tier.
  3. Scalability: More resources can be added to each tier without necessarily affecting the other tier.
  4. Offers Flexibility: Each tier can be expanded in any manner that you dictate based on your capabilities.
  5. Ease of Adding New Features: Separation of tiers ensures that you can introduce a new feature and add it to the desired tier without getting in contact with the other tiers.
  6. Efficiency in Development: Each tier can be separately managed and worked on by different teams or professionals.
  7. Re-Usable: Because the application is divided up into entirely different tiers, you can easily re-use each tier for a different project. For instance, if you need to use the same program albeit on a new data set, you can replicate the logic and presentation tiers and then create an entirely new data tier.

Detracting factors of the Technology

  1. More networks, computers, and processes are involved and therefore, if the hardware and network bandwidths are not good enough, the performance of the whole application or website may be slow.
  2. The overall structure is complex, expensive, and difficult to implement and maintain. Therefore, a lot of effort is needed to manage tasks.


As you can see, we at DinarDirham take great pride in putting the security of our clients’ assets as our first priority. We are very thankful for the existence of such security technology as it has helped us ensure that our clients feel safe as they use any of our products. We hope that you too can see how it has benefitted the overall security of our products. Again, this is just one of the many security features that we have adopted to ensure the safety of our products whether in our hands or in the customer’s hands. We highly encourage you to check out our blockchain and gold-based products at our main website, particularly, our gold price-backed token, the DinarCoin.
