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.
Decentralized communication protocol WalletConnect is embarking on the next phase of its growth with Smart Sessions, a new standard that will “redefine” wallet UX for the AI-powered future of the internet. In a new blog post, WalletConnect Foundation founder Pedro Gomes outlined his vision for a “seamless, intelligent onchain world” powered by AI agents communicating through Smart Sessions. “Smart Sessions aren't just a UX upgrade,” Gomes wrote, explaining that they “fundamentally reshape the ec...
Ethereum co-founder Vitalik Buterin wants to make it easier for average users to run Ethereum nodes by changing how they sync with the network, using regular consumer hardware. On Ethereum, a node can be built on any computer able to run its software and connect with others to share and verify data across the network. Working together, they validate transactions and maintain Ethereum's security. Having a full node is valuable as it means a user can maintain a local server that could run Ethereum...
When Netflix quietly announced plans to remove “Bandersnatch”—the groundbreaking interactive episode from Black Mirror—futurist and journalist Katie Schultz launched a campaign to preserve what she calls a pivotal moment in streaming history. Outraged at what she saw as the quiet erasure of a significant chapter in streaming innovation, Schultz launched a Change.org petition to preserve Bandersnatch—and within days, it gathered more than 6,500 signatures from show supporters. “This isn't just ab...
