A new patent application from IBM describes a blockchain-based web browser.

Filed on August 6 by the United States Patent and Trademark Office, IBM’s patent is for a web browser backed by a peer-to-peer network.

The browser collects pre-specified information from web browsing sessions, according to the patent. Browsing on a work computer versus a personal browser would demand different settings, for example.

As the company states, a blockchain-based browser “affords a system for storing browsing information such that privacy is preserved and places privacy in the ‘hands of a user’ rather than a third party.”

One potential use-case the document includes, among others, is an attack on a computer’s browser. IBM says tokens will verify a users browser session activities as they are packaged into blocks for the peer-to-peer network.

IBM’s blockchain web browser concept is not the only one in the field, however.

Norwegian web browser Opera company recently launched their iOS Opera Touch browser in June. Built for Web 3.0, Opera Touch has a built-in cryptocurrency wallet and connects seamlessly to Web 3.0 applications including ERC-20 tokens.
