The Chrome development team is planning in a future version to enable support for Signed HTTP Exchanges (SXG). It will allow you to store verified copies of web pages on other sites, they will look like the original. As noted, for the formation of the signature is used full-time private key of the TLS certificate with an active extension CanSignHttpExchanges.
Protocol support is necessary for security, since technology AMP (Accelerated Mobile Pages) gives the user the cached version of the page. SXG will allow you to certify copies of pages of an electronic signature that will solve the problem with displaying in the address bar of another domain and eliminate the possibility of MITM attacks. SXG in Chrome will improve safety and will make it impossible to create a fake page requesting username, password, and financial information.
In addition, the technology will allow SXG to extend the web application in a mode peer-to-peer without a Central server. Finally, this technology will find use in content delivery networks (CDN). At the moment support SXG is already in Chrome 71, but its not yet activated.
