HBD @ethereum. Over 10 years ago, I got into crypto thanks to my lab mate @loi_luu’s btc mining pool research in 2014 and @VitalikButerin’s seminar back on 3 Jun 2015, when he presented @ethereum and blockchain tech at @NUSingapore . Then back in 2016 when doing more research on p2p privacy, was lucky to have tech discussions with Vitalik on Ethereum p2p issues like potential eclipse attacks and solutions. Good old days.
