Ethereum 2 Roadmap, Buterin’s Open Problems and Findora’s Auditable Privacy are great models for bringing the best research results — via our $7M grants — to Harmony Mainnet.

Lecture Abstract

Ready for Ethereum 3.0? In this talk, Stephen Tse covers cryptography already in use on blockchain mainnets such as Ethereum, ZCash and Harmony. Highlights include non-custodial exchanges with zero-knowledge rollups, stateless clients with a logarithmic number of headers, and cross-chain composability for decentralized finance. He surveys the latest usage metrics, competitive landscape and why cryptography is the 1000x magic for building open platforms.

Outline of research notes at

Stephen also focuses on scaling cryptography by bringing the best research results to production. With this engineering approach, Harmony achieves high performance by optimizing its consensus protocol with Boneh–Lynn–Shacham signatures, securing sharding membership with unbiasable randomness, and compressing delegation states for open staking.

Cross-chain composability for recent explosion of decentralized finance.

About Harmony

Harmony is a fast and open blockchain for decentralized applications.

Our protocol has achieved secure and random state sharding. Harmony Mainnet supports thousands of nodes in multiple shards, producing blocks in a few seconds with instant finality. Our staking mechanism reduces centralization while supporting stake delegation, reward compounding and double-sign slashing.

Are we decentralized yet? Harmony aims to build an open network of nodes operated and governed by a large community.

About Stephen Tse

Stephen (Harmony Founder & CEO) has been obsessed with protocols and compilers since high school. He reverse-engineered ICQ and X11 protocols, coded in OCaml for more than 15 years, and graduated with a doctoral degree in security protocols and compiler verification from the University of Pennsylvania.

Stephen was a researcher at Microsoft Research, a senior infrastructure engineer at Google, and a principal engineer for search ranking at Apple. He founded the mobile search Spotsetter with institutional venture capital; Apple later acquired the startup.
