While Chrome's version of WebCore followed its development, a large amount of the original WebCore's code was dedicated to enabling features which Chrome does not use (such as its sandboxing and multi-process model in WebKit2, which differs from Chrome's implementation). By forking, Chrome developers were able to simplify the codebase by removing unneeded code, while also giving them greater flexibility in adding new features. The fork will also deprecate vendor prefixes; experimental functionality will instead be enabled on an opt-in basis. Aside from these planned changes, Blink currently remains relatively similar to WebCore. By commit count, Google has been the largest contributor to the WebKit code base since late 2009.
Blink's naming was influenced by the non-standard presentational blink HTML tag, which was introduced by Netscape Navigator, and supported by Presto and Gecko-based browsers until August 2013. Blink is a trademark of Open Source browser software company Nuanti, registered with the U.K. Intellectual Property Office. Nuanti is one of the original code contributors and maintainers of the browser's graphics subsystem prior to Google.
