Harmony is an EVM compatible layer-1 blockchain that uses a a proof-of-stake (PoS) consensus mechanism with its mainnet launched in June 2019. It claims to be the first platform to combine PoS and sharding to improve scalability. It uses four shards each with a limit of 250 validators and claims to have maximum throughput of 2,000 transactions per second. Its native token, ONE, can be used to pay for transactions, staking and on-chain governance; however, it burns all transactions fees.
Its Beacon Chain or Shard 0 is responsible for transmitting information between the other three shards while it also offers an Ethereum-Harmony cross-chain called Horizon, which allows developers to interact and transact between the two networks.
In September 2021, the company launched a USD 300 million ecosystem fund to offer investments and grants to startups working on applications and protocols on its network. The platform supports various dApps such as GameFi, DeFi, DAOs, metaverse, and NFT marketplaces.
Key customers and partnerships
The company partnered with Singapore-based Game Space , a GameFI-as-a-service platform, to help Web2 game developers onboard Web3 functionality. The two companies also planned to promote blockchain games and NFT-related projects to boost Web3 adoption.
Funding and financials
Harmony raised USD 18 million in a token presale in April 2019 from various investors including Lemniscap VC, BCA Fund, UniValues Associates, and Consensus Capital, who purchased over 2.8 billion tokens.
