The Future is here: Blockchain Technology and Smart Card

We are inundated with information from a diverse set of blockchain applications—crypto currencies, funds transfers, asset registries, and the Internet of Things (IoT) payment. We are so busy that we don’t even have time to keep our information safe. I am sure there is a way to solve the issues starting from security to scalability and ease of use.

We are quite sure that this type of conversation often plays out in the corporate corridors these days. While business leaders know how to run their business in general, they are also looking for help in generating, storing, and managing the user’s cryptographic keys of the Blockchain applications so that they can concentrate on their business. If keys can be stored and accessed securely then handling cryptographic keys of the Blockchain applications can stop becoming a burden and turn into a pillar of strength.


How does one break this deadlock and secure data of Blockchain applications? Smart card and blockchain technology is a perfect match for proper management of cryptographic data of applications. They are like cheese and wine, delivering the life’s greatest information security pleasures.

The blockchain is a revolutionary technology that helps businesses create faster and secure applications that fulfill stringent security requirements. Its crucial innovation”Times New Roman”,”serif””>—decentralized ledger—is secured with the help of cryptographic keys that ensures security, immutability, and no vulnerability in the network. Inspite of these cryptographic keys, applications face common security issues. Therefore, it is essential to manage cryptographic keys effectively, as the loss of any of these keys leads to the permanent loss of the respective Blockchain asset. This is where smart card technology comes into the picture. Smart cards can be used to effectively manage cryptographic keys, thereby enabling efficient and secure transactions in the Blockchain applications. Private keys are stored on smart cards separate from the public keys.

Smart cards are essentially chips that stores data read by machines. They are embedded with microprocessors to allow smooth transactions. These cards are an essential component of most of the credit/debit cards, SIM cards, and hotel key cards, which are considered the most common, used forms of smart cards today.

The mode of installation, the architecture, and configuration of the smart card processor play a vital role in determining the cryptographic operation times. The time required for carrying out complex cryptographic operations has been minimized. For instance, signing a 1024-bit RSA modulus [30] would require a fraction of a second, while hash function evaluations are accomplished even sooner.

Applications of Smart Card Technology

Smart cards have been in use ever since they were introduced. They have revolutionized the way a business operates.

  • A smart card is a hardware capable of performing operations such as key pair generation with minimum power consumption in the least possible time duration. The secure key pairs are capable of handling attacks of a critical and advanced nature of blockchain applications.
  • Smart card technology protects private keys inside hardware with tamper-resistant hardware security and interaction restricted to a limited set of commands and responses, which indirectly increases the overall security of blockchain applications.
  • It provides straightforward access to cryptographic keys. The smart card can be a simple card, USB device, mobile device, microSD, an embedded secure element chip, or a wearable device. These devices enable easy, portable, user-controlled access to the keys for performing Blockchain transactions.
  • They provide Blockchain applications a secure platform and an established, standardized security evaluation and certification program for protecting keys.

Blockchain applications are the new oil, but it is crude, and when used with the help of one of the smart technology smart card will bring new gold nuggets. Smart cards securely store private keys which are part of the cryptocurrency transactions. Blockchain applications with the help of smart cards help businesses earn more revenue and retain more customers.

Should You Upgrade and benefit to Drupal 8 Now?

Drupal 8 has a number of improvements, and this will upgrade is proven to be the last difficult upgrade. You will enjoy all the benefits of Drupal 8 which makes your business stronger, and looking to the future, you will have an upgrade path to Drupal 9 and beyond. You’re not going to gain anything by waiting to upgrade your website. In fact, you will be losing market share to those who are already moving forward.

Drupal 8

Drupal 8 has over 200 new features and improvements over the Drupal 7 release. Drupal 9 was built, from the ground up, to be backwards compatible with Drupal 8. In order to do this, you need to employ developers who really know the underpinnings to convert and clean out older deprecated code that will be removed in Drupal 9. Your upgrades going forward will be painless. Any work done in Drupal 7 will have to be rewritten when Drupal 7 code gets deprecated out. Which is one big reason why you should upgrade now!

The two biggest changes are the mobile first framework Symfony 4/5 and Twig 2.0 scripting for theming. Below outlines what they are and why an upgrade will benefit you now.


Symfony has extensive libraries and offers a lot of functionality that Drupal needs. Symfony also works very well with Twig. This provides a mobile friendly framework that is Object Oriented making APIs to third party products better.

PHP-based Twig is a faster, simpler, more secure theming engine than PHPtemplate engine. Now you can use HTML/CSS and don’t have to know PHP to theme Drupal pages.

Some of the other best enhancements include:


Drupal 8 seamlessly supports mobile, it is fully responsive and will automatically reshape elements to look good on any screen size. Drupal 8 Administrative themes are responsive, making administration easier on a mobile device.


We all know that website performance is critical for your business and to rank well on the search engines. Drupal 8 delivers – utilizing Facebook’s BigPipe Technology to load content much faster through caching.

Entities are stored in cache and JavaScript loads upon demand, which dramatically increases the speed of your website. Caching is fully automatic and configurable. JavaScript computerized testing is automatic manner, making integration easier and more reliable.


Layout builder can create custom visual layouts arranging content on a page or across different content types using a drag and drop interface.


The WYSIWYG editor is now integrated into its core, making it more user-friendly with the seamless creation and formatting of the content for nontechnical admins. Media handling is much easier.

Drupal 8 has four core modules that allow the full translation of everything with dynamic, language-based displays, using multiple admin languages and translation workflows.


A system-based configuration management system (collection of admin settings that determine how the site default functions) improves the use of Git, by allowing the versioning of the configuration without production data.


Drupal 8 Varbase provides an easy to use backend with an excellent graphic user interface that provides: Fully Optimized On-page SEO, Responsive Previews & Mobile Ready, Easy Media Management, Landing Pages Creator, graphical admin dashboard, Social Media Tools, Multilingual Translation and Advanced Web-forms. We have deployed Drupal 8 website with Varbase and our customers absolutely love how functional and easy it makes website administration.

Drupal 7 End-Of-Life (EOL) 

Drupal 7 and Drupal 8 versions EOL is November 2021, which means no new features, no bug fixes, no Security Advisories and no vulnerabilities reported for core or contributed modules, themes. Now that Drupal 8 is stable and the contrib modules are all completed, it only makes sense to work in Drupal 8 going forward.

All of these capabilities are far above what is currently in Drupal 7 or Drupal 6, for that matter. Many times, our customers wait for the next release, which in case would be Drupal 9. However, the beauty of upgrading now is you can get those capabilities now which make your business more competitive and successful. So, what are you waiting for? Upgrade now!
