Many websites online have been using the power of visitors hardware to mine cryptocurrencies which is considered not fair. This is possible by embedding a script into their website and whenever a user browse their site, the script starts making use of their computer processing power. The scripts may not be quickly detected on desktop PC’s due to the minimal effect it has on it but cannot be said as same for users with mobile phones.
Today, Opera has announced that Opera Mini and Mobile for Android will come with a crypto-jacking feature to help protect its browser from crypto scripts. The blocking feature has already been implemented in their desktop browser this month. Smartphone users who make use of Opera’s mobile browsers will see improvement in terms of speed and responsiveness.
It is worth mentioning that Opera is the first major browser to implement such kind of protection in its desktop line and now doing same for its mobile browsers in order to halt Cryptocurrency mining scripts.
Jan Standal, VP Product Marketing at Opera says:
When you browse the web, there are no visual clues that your device is exposed to mining
A single webpage you visit can take up to 4.5 hours of your battery time, if you keep the tab open. This often turns out to be just the battery time you needed to use a ride-hailing app or check the map to get home
Opera Cryptocurrency mining protection which may yet be fully available can be tested at Cryptojacking Test to see if it works as expected. The website helps users to check if their browser is affected by Crypto mining activities.
