What is the technology behind Signal? — Sofvare Solutions LLP
Encrypted messaging app Signal is witnessing tremendous growth as it has now been ruling at position 1 on the “Top Free Apps” section of Apple and Google’s App Store (in 40 countries). On the other hand, WhatsApp is seeing a decline following a major update concerning the privacy of more than 2 billion users. Owing to this, WhatsApp (by Facebook) was forced to release clarifications regarding what information will be used and in what sense.
Signal is an independent nonprofit. They are not tied to any major tech giants and will never be acquired by the other. All the development is possible by grants and donations made by people like you.
In 2017, Brian Acton, co-founder of WhatsApp, left WhatsApp. Brian in an interview with Forbes stated he left over a dispute with Facebook regarding the monetization of WhatsApp. He voluntarily left $850 million in unvested options a few months before vesting was completed. He also noted that he was coached by Facebook executives to mislead European regulators regarding Facebook’s intention to merge Facebook and WhatsApp user data.
In 2018, Acton invested $50 million in Signal Foundation, a cheque to keep the games on. Signal from then on relies on grants and donations.
“If Signal gets to a billion users, that’s a billion donors. All we have to do is get you so excited about Signal that you want to give us a dollar or 50 rupees. The idea is that we want to earn that donation. The only way to earn that donation is building an innovative and delightful product. That’s a better relationship in my opinion” -Brian Acton
After the buzz of the recent WhatsApp updates, Elon Musk tweeted and told his followers to use Signal.

Providing the best alternative to any instant messaging providing end-to-end encryption, Signal in less than 12 hours became talk-of-the-town (globe to be precise).
As per several tech channels, the application has gained over 65 million new users in less than a week. The proof of this can be seen in Playstore stats (released by Signal on Twitter).
Let’s briefly discuss the Technology used behind Signal
Signal is an open-source project, the users can get direct access to its code via G itHub, which means its privacy and security can be regularly checked by independent experts.
Signal’s USP is its focus on privacy. The encrypted app allows users to send messages and make calls via the internet. It supports group chats and video calls too.
Signal for Android is built using Java, Signal for Desktop is developed on JavaScript, Signal for iOS, and developed using Swift and the server is built in Java.
Signal’s Future Plans
The company recently hosted Ask me Anything (AMA) on reddit in order to answer any questions regarding their business standards, gain feedback from old and new users, and interact with the users.
Few possible major updates include:
- User ID System:
Telegram has adapted this system, where a user can pick a unique id and can just share this id, allowing the user’s to keep even their phone number secret. - Will they be able to sustain the application with this increasing user base without Ads?
Signal is structured as a non-profit and is supported by billions of users, similar to organizations like Wikipedia. They will never sell ads and have designed the app in a manner that they know nothing about their users, and so there is no chance of target ads. - Working on Backups and automatic chat transfer on Android/iOS. Support for simple markdown like bold, strikethrough, underline, etc.
- The company is aware of Linux users and will probably roll out distributions for officially supported versions in the future.
- Localization
The app is currently localized into more than 100 languages. They will keep doing so for other languages as well.
Owing to significant growth and answering several questions, the organization with less than 50 members was on foot for hours.
“The growth is just amazing, it’s been so fast in the last 72 hours that not too many of us have gotten very much sleep. That’s a good problem.” -Brian Acton
