Key Takeaways

  • Telegram pushed a major upgrade earlier this week, adding blockchain-like encryption for Telegram voice and video calls.
  • The firm also launched several new gesture features and a gift management system.
  • Over the years, Telegram has transformed itself into a Web3 frontier.

Popular social media and messaging platform Telegram has introduced blockchain-inspired encryption for voice and video calls, with the option to add tens of thousands of participants via group calls.

The move will make internet calls on the platform more secure and accessible as the small team-driven company aims to grow its user base.

Telegram Opts for Blockchain Encryption

The latest update from Telegram allows for extremely secure group calls. Calls are safeguarded using blockchain-like technology and end-to-end encryption to ensure that nobody can tap into them, enhancing the security and privacy of its users.

The call feature was first introduced in 2021, and since then, the company has introduced several updates to enhance users’ experience and connectivity.

The latest update allows users to use links, QR codes, or direct invitations to invite up to 200 people to any Telegram call, including one-on-one calls. Telegram audio and video conversations can accommodate tens of thousands of participants in groups.

To confirm security, the encryption can be verified by comparing four randomly generated emojis on the screen. These calls use a distributed security architecture similar to blockchain technology and end-to-end encryption.

Telegram underlined its long-standing dedication to security by highlighting its open-source code and announcing a $100,000 reward for anyone who can crack its encryption, which has gone unclaimed for more than ten years.

Telegram Continues To Push Web3 Innovation 

The latest security upgrade with blockchain technology integration highlights its commitment to its Web3 promise.

Over the years, Telegram has pushed Web3 user-centric updates and features from time to time, be it NFT integration or crypto wallet support. 

The latest encryption features come just a month after the firm introduced Grok AI, a chatbot that enables users to have conversations with it. 

Telegram’s latest upgrade includes additional gesture controls, improved Telegram Business capabilities, a simplified appeals process for account restrictions, and end-to-end encrypted group calls. 

The company has begun rolling out the new features, and all users should be able to access them in the next few days.
