Please don't shoot me 
I too reacted the same way when I read the topic title.Infact,being an optimistic blockchain supporter,I didn't even bother to open the article until the geek inside me pushed me to.Anyway,I was surprised.I mean we should embrace the changes right ? Here ya go,welcome HashGraph.

If hashgraph beats blockchain. Will bitcoin and other blockchain coin die?

The new consensus algorithm
Introducing Hashgraph a fair and fast, byzantine fault tolerant consensus algorithm. According to the founding Hashgraph team consisting of computer science and cybersecurity pioneers Dr. Leemon Baird and Mance Harmon, the hashgraph consensus method achieves the following notable feats:
Its fast: 250,000+ transactions per second and limited only by a users bandwidth (Pre-Sharding)
Its fair: mathematically proven fairness (via Consensus Time Stamping)
Its secure: bank-grade security (Asynchronous Byzantine Fault Tolerant)
Why is Hashgraph superior to Blockchain?
