Get to know some alternative message solutions based on Blockchain

We live in an age where we are always in touch with other people, and today the WhatsApp application is a favorite to do so. But does Blockchain have no alternatives?

Since being acquired in 2014 by Facebook WhatsApp has never stopped growing. It currently has more than 1 billion users per month and more than 30 billion messages a day are transmitted. With increasing concern about user privacy, messaging has been increasing its security by adding a two-factor verification layer and automatic end-to-end encryption. But is it enough?

In January 2017 it was reported that the encryption protocol used by WhatsApp could be exploited. This means that although messages are encrypted on both devices so that they can not be read during the transmission, they are decrypted locally on the smartphone. To verify that the device receiving the message is the intended recipient, each user has a public key. This key can be changed when you reinstall the application or switch to a new phone.

The original story, published by The Guardian newspaper, said that since WhatsApp had the ability to change security keys for offline users, it is possible to intercept and decrypt messages. WhatsApp could force you to resend your messages with the new security key and allow access to the messages.

This is just one of WhatsApp's problems, as well as data sharing between the messaging application and Facebook and the fact that message backups made to "ordinary" cloud accounts such as iCloud and Google Drive are not encrypted.

Nowadays, we regularly see that Blockchain can bring many benefits to the world. Can messaging applications also help? There are several messaging applications that, in addition to offering the ability to send instant messages, also allow users not to worry about cases of theft or data manipulation.

Stick with three examples of messaging applications that use Blockchain in their services.

Kakao Talk
This application has a concept similar to Skype. Kakao Talk allows you to call your contacts for free and exchange instant messages. Like other applications, just the phone number to register. Kakao Talk is available for Android, iPhone and Windows Phone, on mobile phones, and for computer. The PC version allows you to send files up to 100 MB and you can also set the lock mode for greater privacy protection.

Status is a Blockchain-based application that operates as a messenger and decentralized browser. However, it is important to note that Status is not like the ordinary messaging service; in addition to chatting, Status allows you to send Ethereum-based payments and issue smart contracts to friends. The platform also gives users the opportunity to interact with decentralized applications running on the Ethereum network. In this way, the application transforms the device into a client node that has the ability to access the Ethereum ecosystem from anywhere.

The last application on this list is Vibeo. It's another Blockchain-based application designed to bring communication to the next level. Users can communicate individually or even set up conference calls. Vibeo supports voice and video calls and you can use instant messaging. All interactions on the platform occur safely and in Blockchain.
