Blockchains are just Databases? Right?

The emergence of blockchain technology has brought about a paradigm shift in how data is stored and managed. While traditional databases have been the backbone of data management for decades, blockchain technology has the potential to revolutionise this space. In this article, we will explore the reasons why blockchains are better than databases.

Decentralization and Transparency

One of the key advantages of blockchain technology is its decentralization. Unlike databases that are managed by a central authority, blockchains are distributed across a network of nodes. This means that no single entity has control over the data, and all nodes in the network have access to the same information. This decentralization makes blockchains more resistant to cyber-attacks and data breaches since an attacker would need to compromise a majority of nodes in the network to manipulate the data.

Furthermore, the transparency of the blockchain makes it easier to track the history of transactions. Every transaction is recorded in a block, which is then added to the chain of previous blocks. This creates an immutable ledger that cannot be altered without the consensus of the majority of nodes in the network. This transparency is particularly useful in applications such as supply chain management, where it is important to track the movement of goods from one location to another.

Improved Security

Blockchains use advanced cryptography to secure the data stored on the network. This means that the data cannot be altered without the proper cryptographic keys, making blockchains more secure than traditional databases. Furthermore, the decentralized nature of blockchains means that there is no single point of failure. If one node in the network is compromised, the other nodes can continue to operate and maintain the integrity of the network.

Smart Contracts

Another advantage of blockchains is the ability to use smart contracts. Smart contracts are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. These contracts are stored on the blockchain and automatically execute when the conditions of the contract are met. This eliminates the need for intermediaries, such as lawyers and banks, which can reduce transaction costs and increase efficiency.

Cost Efficiency

Blockchains can also be more cost-efficient than traditional databases. Since blockchains are decentralized, there is no need for a central authority to manage the data. This means that the costs associated with maintaining a central database, such as servers and IT staff, can be significantly reduced.


In conclusion, blockchains offer several advantages over traditional databases. The decentralization and transparency of the blockchain make it more secure and resistant to cyber-attacks. Smart contracts eliminate the need for intermediaries, reducing transaction costs and increasing efficiency. Furthermore, the cost-efficiency of blockchains can make them a more attractive option for businesses and organizations looking to manage their data in a more secure and efficient manner

What is OAuth 2.0 and why every company uses it

Secure your organisation using OAuth 2.0

OAuth 2.0 is a widely used authorization framework that provides a secure and convenient way for businesses to access APIs. APIs, or application programming interfaces, are the backbone of modern web and mobile applications. They allow different software applications to communicate with each other, enabling data sharing and providing valuable functionality. However, in order to ensure the security of the API, it’s important to use an authorization framework like OAuth 2.0.

OAuth 2.0 is an open standard that allows businesses to provide secure access to their APIs. It’s widely used by companies such as Google, Facebook, and Microsoft, as well as many other businesses. OAuth 2.0 works by providing access tokens, which are used to authenticate and authorise API requests. The access tokens are issued by an authorization server, which ensures that the API requests are coming from an authorised source.

There are several benefits to using OAuth 2.0 to secure your API. First and foremost, it provides a high level of security. By requiring access tokens, you can ensure that only authorised users and applications are able to access your API. This helps prevent unauthorised access and protects your data. In addition, OAuth 2.0 is a widely recognized standard, which means that many developers and businesses are familiar with it. This can make it easier to integrate your API with other applications and services.

Another benefit of using OAuth 2.0 is that it can help improve the user experience. OAuth 2.0 allows users to grant permissions to third-party applications without giving away their login credentials. This can be a major convenience for users, as they don’t have to create new accounts or remember additional login information. This can also help improve user engagement, as users are more likely to use an application that integrates seamlessly with their existing accounts.

In conclusion, using OAuth 2.0 to secure your API is a smart choice for businesses looking to provide secure and reliable access to their data. It provides a high level of security and improves the user experience. If you’re considering using an API in your business, it’s important to take the necessary steps to secure it. OAuth 2.0 is an excellent option to consider

The importance of DMARC

In today’s world, email has become an integral part of both personal and professional communication. Unfortunately, this has also led to a rise in email fraud and scams. As a result, many organizations have adopted Domain-based Message Authentication, Reporting, and Conformance (DMARC) as a means of protecting their email infrastructure from these threats.

DMARC is an email authentication protocol that is designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing. DMARC allows the domain owner to specify which mail servers are authorized to send email on behalf of their domain. In essence, DMARC is a policy that tells email receivers what to do with email that fails SPF (Sender Policy Framework) and/or DKIM (DomainKeys Identified Mail) authentication checks.

One of the main benefits of DMARC is that it helps to prevent phishing attacks. Phishing attacks are fraudulent emails that are designed to look like they are from a legitimate source, such as a bank or an e-commerce site. These emails often contain a link that, when clicked, leads the recipient to a fake website where they are asked to provide sensitive information. By implementing DMARC, organizations can reduce the likelihood of these types of attacks by ensuring that emails from their domain are only sent from authorized mail servers.

DMARC also helps to improve email deliverability. When an email fails DMARC checks, the receiving server can be configured to reject the message, quarantine it, or mark it as spam. This means that legitimate emails sent from unauthorized servers will be blocked, while legitimate emails sent from authorized servers will be delivered. By improving email deliverability, organizations can ensure that their messages are reaching their intended recipients.

In addition to improving security and deliverability, DMARC also provides valuable reporting information. DMARC reports provide organizations with information about how their domain is being used, including the number of messages that are being sent, which servers are sending them, and whether or not they are passing authentication checks. This information can be used to identify potential security issues and to optimize email delivery.

In conclusion, DMARC is an essential tool for protecting email infrastructure and reducing the risk of email fraud. By implementing DMARC, organizations can prevent phishing attacks, improve email deliverability, and gain valuable insights into their email traffic. As email continues to play an increasingly important role in communication, the importance of DMARC will only continue to grow.
