A recent endorsement by Tesla CEO Elon Musk has propelled privacy-focused messaging app Signal to the very top of major app charts—partly thanks to WhatsApp’s recent controversial announcement.
Use Signal
— Elon Musk (@elonmusk) January 7, 2021
“Use Signal,” Musk tweeted on January 7—a day after Facebook-owned WhatsApp, one of Signal’s competitors, began pressuring its users to share their personal data with its parent social media.
According to app analytics platform App Annie, Signal is currently the most popular free app on both AppStore and Google Play. WhatsApp, on the other hand, is ranked 13 on iOS and 27 on Android.
Signal is known for using an end-to-end encryption (E2EE) protocol. In cryptography, this method is used to establish a communication channel between two parties that is impossible to “eavesdrop” on.
In E2EE, special encryption keys are created on a sender’s device, which only the recipient is able to decode. This means that data is protected not only from hackers and other malicious actors but from the Internet, server, and service providers as well. While the message itself can be intercepted and copied, it cannot be decoded without the appropriate keys.
“I trust Signal because it’s well built, but more importantly, because of how it’s built: open source, peer reviewed, and funded entirely by grants and donations. A refreshing model for how critical services should be built,” Twitter CEO Jack Dorsey said in the past.
Private messaging app Signal has become the most downloaded app across both iOS and Android platforms in Hong Kong, following the adoption of a Chinese law that impacts free speech within the special administrative region. Mobile app analytics firm App Annie reports (via Bloomberg) that the app has topped the charts for both Apple’s App Store and the Google Play Store in Hong Kong, which has more than 7.5 million residents. On Tuesday, Hong Kong began enforcing the Law of the People's Republic...
After WhatsApp’s announcement, Edward Snowden, America’s most notorious whistleblower, also confessed that he is using Signal every day—and still hasn't died from it.
“Here's a reason: I use it every day and I'm not dead yet,” Snowden said in a reply to a user asking whether Signal can really be trusted.

As Decrypt reported, demand for Signal exploded following the surge of protests in the US this summer. At the time, the app just entered into the top 10 apps in the “Social Networking” category on iOS.
Today, it’s the number one overall.
DFZ Labs, the creators of the Ethereum NFT project Deadfellaz, will launch a new asset verification tool that allows users to connect online and offline assets without signing blind transactions or smart contract approvals. Coldlink, now in beta, enables blockchain users to connect their blockchain address to any asset in Web2, Web3, or real life without incurring the security risk of blind signing or smart contract approvals, DFZ Labs said. “To ‘Coldlink’ something is to connect any digital ass...
Scammers are using cracked versions of TradingView Premium to drain crypto wallets. The app is disguised as a “cracked” version of the real TradingView Premium app. Downloads of the malware infused versions are being distributed via Reddit and have often been found in cryptocurrency sub Reddits. Victims have reported having their entire crypto wallets emptied. They were then impersonated by the scammers, who used their details to send out phishing attempts encouraging the victims’ contacts to d...
In a London office on Thursday, BitcoinOS developers completed the final code commit that would open-source BitSNARK, a specialized protocol enabling zero-knowledge verification on Bitcoin. The move to open-source BitSNARK “unlocks programmability on Bitcoin” and aims to help developers “build and experiment in ways that were previously impossible,” Edan Yago, CEO and co-founder of BitcoinOS, told Decrypt. The release follows BitcoinOS's July 2024 demo, which verified the first zero-knowledge pr...
