What is Harmony?

Harmony (ONE) is a blockchain platform launched in 2019 by Stephen Tse and his team. It was designed to address scalability and decentralization issues in blockchain networks. Harmony operates as a Layer 1 blockchain using a unique consensus mechanism called Effective Proof-of-Stake (EPoS), which enhances security and reduces centralization risks. This protocol enables fast and cost-efficient transactions, supporting applications in decentralized finance (DeFi), non-fungible tokens (NFTs), and other smart contract-based services. The native token, ONE, serves multiple purposes within the Harmony ecosystem, including paying transaction fees, participating in network governance, and staking to secure the network. Harmony is distinguished by its sharding technology, which divides the network into smaller, manageable pieces (shards) to process transactions in parallel, significantly improving throughput and speed. This innovative approach positions Harmony as a significant player in the blockchain space, focusing on scalability, efficiency, and interoperability.

When and how did Harmony start?
