Is there a google like search engine where I can search for text contained in various Ethereum transactions? Maybe I can search for: + Mitch McConnell email address + Lindsay Graham noodz + special edition cryptokitty + chemtrail air force base + chemtrail CIA airport + chemtrail dow chemical + jfk real killer + kidnapping proof of life all sorts of weirdo shit that someone might be writing to the blockchain for either public surreptitious communications, or just to write it down for posterity Is there a search engine in general that will do this for Ethereum, or for Ethereum and other popular blockchains?
