Messaging apps are one of the most popular tools for everyday communication. There are various blockchain messaging apps on the market that integrate Web3 functionalities. The main goal of blockchain messaging apps is to provide users with a reliable, decentralized alternative to mainstream messengers. Blockchains use decentralized networks of nodes to process data. Messenger apps that use blockchains provide users with highly secure and private communication features. These features are becoming highly popular among users who value privacy and security when sending messages. However, centralized messaging apps are still far more popular than blockchain alternatives. Many users aren’t aware of the various blockchain messaging apps that provide top-notch security and preserve user privacy at all times. 

In this article, we’ll explore the key issues that plague centralized messaging apps. We’ll find out what kind of alternatives blockchain messaging apps offer. Also, we’ll look at some of the leading blockchain messaging apps on the market.

Centralized Messengers and User Privacy

Messenger apps like WhatsApp and Facebook Messenger are some of the market’s most popular centralized communication apps. There are numerous centralized messengers, and they follow a similar organizational pattern. Private companies own these messengers and entirely control all the operational aspects of the apps. The companies manage the storage of data and user messages. While some centralized messengers claim that they don’t store messages, others clearly state they store them on their siloed servers. The problem is that users can’t control what happens with their data and who has access to it. 

The main danger regarding user privacy and centralized messengers is potential platform hacks. Centralized messaging networks have closed cybersecurity systems. If a hacker manages to break into such a security system, all of the stored data is in danger. A centralized messenger is only as safe as the network’s security. Furthermore, if an app keeps messaging histories like Facebook Messenger, hackers can get control of all types of private information.

Centralized Messengers and Technical Issues

The centralized nature of mainstream messaging apps allows for numerous potential technical issues. Data shows that apps like WhatsApp and Facebook Messenger are prone to frequent crashes and network bugs. The main reason behind these crashes is the vast, centrally controlled operational mechanism. Keeping a centralized system with hundreds of millions of users smoothly operating is tough. For example, a minor app update regularly causes chaos in a centralized messaging system. That’s because the whole network needs to simultaneously update its mechanism, while a centralized data processing system controls the update process. App updates often cause the entire system to crash, rendering the apps useless until the network recovers. These crashes often take several hours to resolve, considerably disrupting businesses that rely on centralized messaging apps for communication.

When the network receives too many user requests, there isn’t any way to distribute the workload. Instead, all the traffic is processed centrally, leading to crashes. A decentralized alternative relies on numerous network nodes to process traffic and distribute the workload.

Blockchain Messaging Apps

Blockchain messaging apps use the sharp opposite regarding network structure compared to centralized messengers. These apps use blockchain technology to facilitate communication between users through blockchain transactions. Blockchains are a type of distributed ledger technology, essentially a decentralized network structure. Instead of one centralized system that processes traffic, blockchain messaging apps use many autonomous network nodes. 

The decentralized app structure makes blockchain messengers much more stable. Since numerous nodes process transactions, the network isn’t over-encumbered. Also, blockchain apps have potentially better security since they don’t use centralized servers. A hack of a few nodes won’t bring the network down. Additionally, blockchain technology focuses on preserving user privacy. Blockchain messaging apps don’t store user data or messaging history on company servers. 

Blockchain messaging apps are a good alternative to centralized apps in terms of security and privacy. However, these messenger apps are far from mainstream adoption, and their user base is far smaller than that of the leading centralized messengers.

Dust: One of the First Blockchain Messaging Apps

Dust is a veteran blockchain messaging app launched in 2014. The app uses blockchain technology to facilitate communication between users. Dust comes in the form of a classic messaging app that connects users through their mobile phone numbers. Users don’t need to provide additional data besides their phone number, which means the app is pseudonymous. Messages use end-to-end encryption; no one can view the message contents except the senders and receivers.

Dust is known for its “dusting” feature, which automatically erases all messaging history after 24 hours. Users can also delete messages themselves after reading. Plus, the platform doesn’t store messaging history anywhere. When a user deletes a message, it’s gone forever, and there’s no record of the message. Also, Dust has an integrated stealth search feature that allows users to browse the web anonymously.
