Consensus Consensus is the core of any blockchain. Harmony integrates an efficient consensus protocol that combines POS with practical Byzantine fault tolerance (PBFT). Smart Contracts We will discuss latest ideas about deploying smart contracts in a high throughput, low latency environment and within a sharded blockchain architecture. Networking If you’ve been thinking a lot about networking, like some of our team members, check out our recent open-source contribution — Libunison, an end-ton-end (E2E) / peer-to-peer (P2P) networking library to support highly scalable and performant blockchain networks. Sharding Harmony scales to tens of thousands of nodes with full sharding of computation, states and communication. Inspired by Omniledger and Rapidchain, our approach incorporates staked voting and secure randomness for a modern scalable architecture.
