She discussed many major research challenges and technical gaps existing between theory and practice in crypto currency domain. To make the students understand better, the presentation barely had any technical terms and was explained well with many examples. The session was very interactive and multiple questions were presented giving everyone a chance to think including the speaker. This session is very useful for our students to familiarize the functional/operational aspects of crypto currency Ecosystem and able to understand the emerging abstract models for Block chain Technology. The students felt very enlightened and are eager for another guest session, since these sessions give students a chance to get acquainted with the buzz going around in the corporate world. At last, the vote of thanks was proposed by Mr. Harichandar.D, Final Year B.E/Mechatronics. Totally 110 persons were benefitted from this program.
