Harmony Protocol aims to scale blockchain to 10M transactions/second and 100-millisecond latency. Harmony will bring 1,000x speed and capacity to the next generation of the decentralized economy, enabling marketplaces for 10B people and 100B devices.
Harmony builds an open marketplace at Google-scale for the decentralized economy. This project aims to provide a consensus protocol over the open Internet at 10 million transactions per second with 100-millisecond latency and at most 0.1% fee. Harmony’s goal is to be 1,000+ times faster and cheaper than Bitcoin and Ethereum. We are
rebuilding the decentralized economy with 10x innovations in all components: transport network (Google’s UDP, Bloom tables, 5G mobile), consensus protocol (Byzantine committees, acyclic graphs, monopolist fees), and system tooling (unikernels, multi-core in Rust, zero-copy streaming).
We believe communication is the key to the future of humans and machines to create in harmony. As the gateway for microtransactions or online business, our fee must be at most 0.1% of the transaction value to support new marketplaces of metered content or fractional work.
As the infrastructure for the world’s data firehose, our bandwidth must scale to 10M tx/sec to support data from supply chain IoT devices or energy grids. Yet, all of the above must settle agreements within 100 milliseconds to support instant reactions for autonomous robots or on-chain quotes in exchanges.
We employ technical innovations that are already proven in research and implementation. For example, Google’s UDP currently powers 35% of its traffic (or 7% of the Internet) with 50% latency improvement, OmniLedger Byzantine protocol benchmarks to 13,000 tx/sec and 1.5 sec latency with 1,800 hosts, while unikernels in Rust archives 10M concurrent connections on a standard 96-core machine on Amazon Cloud.
