Scalable and secure blockchain for a radically fair eonomy
Harmony is a scalable blockchain platform for a radically fair economy. It is one of the early blockchains to support sharding, having more than 4 shards of 1000 nodes at the time of writing. With those networks, they can produce a block in 5 seconds with finality.
Harmony uses a modified version of Proof-of-Stake consensus called Effective Proof-of-Stake (EPoS) which they claim to reduce centralization while supporting stake delegation, reward compounding, and double-sign slashing. At the time of writing Harmony has more than 17 million blocks and 10 million staked coins, with more than 130k transactions. Harmony is headquartered in California, United States.
