Reading through chainparams.cpp in the source code I find this line:
const char* pszTimestamp = "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks";
This is the same message that appears in the genesis block for Bitcoin. I think it would be a nice idea if we changed this message to reflect something about Zcash and about the time of its release (28 Oct 2016).
As I understand the message was purely to “anchor” the genesis block to a particular time in history. Yes, it is interesting it was a British newspaper.
