	% To explain the paper's contribution we can simply break down the title:
	% privacy-preserving and incrementally deployable support for Certificate
	% Transparency in Tor.
	%
	% To make a long story short, Tor Browser does not support Certificate
	% Transparency.  The reason why you want to do that is because it makes it
	% possible to detect if visited websites are being impersonated or not.
	%
	% For example, an attacker may want to impersonate a website to steal a
	% user's credit card number.  It is also helpful to de-anonymize a Tor user.
	%
	% So, our work focus on adding support for Certificate Transparency in Tor
	% Browser.  We do that while focusing on two key properties.
	%
	% The proposed solution should be _privacy-preserving_.  We achieve this
	% because of and how we use Tor.
	%
	% The proposed solution should also be incrementally-deployable, and in the
	% end have a stronger threat model than current Certificate Transparency
	% deployments in Chrome and Safari that trust so-called CT logs blindly.
	%
	% In more detail, our incrementally-deployable design goes from:
	%     pairs of CT logs that are trusted blindly, to
	%     at least one CT log is trusted blindly, to
	%     no CT log that is trusted blindly.
	%
	% It is fair to say that we have a strong threat model where the attacker
	% even has a zero-day exploit against Tor Browser.  In spite of this very
	% strong threat model, the involved performance overhead is modest.
