This talk during San Francisco Blockchain Week covers Harmony on 1. uniform scaling at 500 tx/sec per shard, 2. social wallets with One-Time-Password (OTP), and 3. economics games & fair prices for NFT markets.

In the midst of winter, I found there was, within me, an invincible summer. And that makes me happy. For it says that no matter how hard the world pushes against me, within me, there’s something stronger – something better, pushing right back. – Albert Camus ❄️
