What is Web 3? 
Web 3 is the internet of the future. But can’t be defined to just one of several converging technologies and trends, as there are so many.
One thing we know for certain, it will include cryptocurrencies, Blockchains, and other products of cryptoeconomic design. It’s supposed to encompass any technology that helps reform the centralized internet and lets users take back control over their digital lives. 
Krystian Kolondra, EVP at Opera, Head of Browsers, said: 

Blockchain technologies bring the power and control back to the people, they can securely sign transactions and identify themselves to websites, without unnecessarily oversharing their data.”‘

“The web has transformed our lives. We are now continuously online. But the more time we spend online, the more we need tools that help us control the security and privacy of our digital lives. With this Major upgrade, we are taking the first step into Web 3, the new Web, where users are in control. We believe every browser in 2019 should be Web-3 ready.” He added.

Sign transactions with your smartphone

The crypto Wallet in the Opera computer browser syncs with the crypto Wallet in the Opera browser for Android. This means wallet keys never leave the users’ smartphones. In practice, whenever they need to identify themselves to a Web 3 website or sign a transaction on the Blockchain, users get a notification on their smartphone. They can confirm it in the same way they unlock their system, using, for example, facial recognition or their fingerprint.
Krystian Kolondra says:

Blockchain technology has evolved from just storing funds or speculation into a technology which will shape the Internet of tomorrow. We decided to speed up the development of Web 3 by opening all our browsers across all operating systems to it. This makes Opera the first major browser developer to do so.”

The Crypto Wallet feature is planned to also be added to Opera’s iOS browser, Opera Touch, soon.

A faster VPN service for more security and privacy 

The demand for VPN services keeps growing. Currently, one-third of VPN users around the globe use this solution with the intent to stay anonymous on the Web. Opera is the only browser maker to provide a fast and free browser VPN. 
The unlimited browser VPN enhances users’ online privacy and improves their security when using public networks they don’t trust. 
The browser VPN establishes a secure, encrypted tunnel which protects users’ data from third parties and hides their geographical location from websites. The browser VPN service is also a no-log service, which means that the VPN servers do not log and retain any activity data, all to protect users privacy.
