Harmony (ONE) is a decentralized blockchain-based platform. The Harmony platform was launched in May 2019 as part of Binance Launchpad's initial exchange offering in May 2019. Since its core network’s launch in June 2019, Harmony has grown and has more than 1,000 nodes as of the time of writing.
The project aims to solve the problem of achieving both scalability and decentralization. The Harmony team also promises to deliver high throughput with low latency and cost. All this is achieved by a combination of a proof-of-stake consensus mechanism and sharding technologies.
Harmony was founded as a company in 2018. In April 2019, the company raised $18 million in funding from investors such as Silicon Valley-based Consensus Capital, Hong Kong-based Lemniscap VC, and others.
Harmony uses random state segmentation (sharding) to improve scalability and speed up transactions and block creation.
Sharding allows the network to divide the database into smaller segments to reduce latency. In addition, segmentation eliminates the risk of network congestion, allowing near-instantaneous transactions.
The segmentation technique is based on a distributed randomness generation procedure that uses an Effective Proof-of-Stake consensus mechanism. This combination ensures security, scalability, and simple and easy verification.
Thus, the Harmony blockchain is divided into four shards (networks). These shards run in parallel, but are verified by separate stakeholder groups. This enables a "division of labour" that makes the blockchain more efficient and reduces latency.
The Fast Byzantine Fault Tolerance (FBFT) protocol used by the Harmony network is an improved version of the BFT protocol. FBFT increases the speed and efficiency of the Harmony network through parallel transaction processing. At the same time, Harmony minimizes communication costs by signing transactions using aggregate signatures, allowing 250 or more validators to reach consensus in less than two seconds. Instead of asking all validators to broadcast their votes, the leader runs a multi-signature signing process to collect the validators’ votes in a multi-signature and then broadcast it.
Harmony is compatible with the Ethereum Virtual Machine (EVM). This maximizes interoperability and allows smart contracts to be deployed and executed in the same way as in the Ethereum network. This allows applications built on Harmony to be fully interoperable with many other blockchains using its native bridge.
Harmony can be used to build decentralized applications in different industries: financial industry, gaming industry, healthcare, etc. Harmony will allow tokenization of physical world assets or issuance of special types of tokens, such as loyalty tokens, credits, etc. A promising direction will be the creation of Harmony-based NFT marketplaces.
The platform is optimized for both enterprise-level and public networks. The platform implements EVM to provide a flexible and scalable environment for developers. The Harmony team has launched Horizon, the Ethereum-Harmony cross-chain bridge. Horizon allows free conversion of funds between Harmony and Ethereum blockchains, including any ERC-20 tokens. The protocol supports trading and has its own ONE utility token, which is also used as the primary way to pay commissions on the Harmony network.
Google Chrome plugins and online wallets are various means of storing Harmony cryptocurrency. Harmony Wallet is available as a plugin for Google Chrome. There are also third-party wallets for storing ONE.
The Harmony platform operates on its native ONE Token. It has several use cases.
First, ONE token is used in staking. Potential node runners need to stake a certain amount of ONE token to be elected as a validator. ONE token holders are also able to delegate their ONE tokens to the existing validators to participate in the staking process. The more ONE token staked, the more secure the network becomes. Elected validators who successfully sign blocks will receive block rewards in ONE tokens as a compensation.
Second, the tokens are used to pay for various Harmony fees, including transaction fees, storage fees, and gas fees.
And finally, ONE token holders are allowed to vote within the platform's government system.
The total supply of ONE tokens equals 21 million. Of the total number of ONE tokens, 22.4% were allocated to the initial seed sale. Another 12.5% were reserved for additional sales on Launchpad. Harmony's founding and development team received 16.9% of the total offering. About 26.4% of ONE tokens were allocated for protocol development and another 21.8% for ecosystem development.
As with other PoS-based networks, Harmony validators stack native blockchain tokens to participate in system validation and receive rewards. The minimum amount of tokens to run an active validator is 10,000 ONE.
However, validators are responsible for their performance. If a validator misses 1/3 of the blocks in an era the validator temporarily loses its slot. And if a validator is spotted double-signing, it loses at least 2% of its stake, depending on how many slots are corrupted, as this behavior is considered malicious. A fraction of the staked tokens is slashed as penalties.Slashing penalties are imposed on both validators and delegators.
For those who want to participate in staking without running a validator, delegating is the best way to participate and earn blockchain rewards. ONE holders can delegate their tokens to existing validators using the official Staking Explorer. A portion of the block reward earned by the validator will be paid to the delegator.
Block rewards earned are stored in a separate delegator reward balance, which can be immediately deposited into the delegator's account balance. Block rewards can also be placed again to achieve a multiplier effect.
The Harmony ONE token can be purchased on centralized exchanges like Binance, Huobi, or KuCoin.
The Harmony ONE token can be purchased on decentralized exchanges like SushiSwap (on Harmony) and SeeSwap.
It is up to you where to buy the ONE token. It is worth taking into account that decentralized exchanges allow you to do this more anonymously, you do not need to pass KYC procedures to use them, on the other hand the cost of transactions may be higher than on centralized exchanges, while there is a risk of your funds being held by the exchange.
To understand if Harmony is a good investment and try to make an ONE price prediction, you need to do your own research on the project.
All the data for research is available on the project page on our website: check out the technical features of the project in this review, try to use the app, see if the information about the team is available and the team is open for communication, and using the project dashboard and the ONE price chart, assess the project usage rates as well as the token price movement and the number of its holders.
The Harmony team consists of 20 employees with a broad experience in economics and technology. Some of the team members used to work for big corporations such as Microsoft, Google, Apple, and Amazon. In particular, they developed Google Maps and Apple Siri.

The Harmony protocol has been audited by Peckshield in January, 2020.
More than 78 dApps have been built on Harmony. The top projects are a DeFi game DeFi Kingdoms, a multipurpose dApp Tranquil Finance developed for the fantasy world Defiraverse, Curve, and Sushi. Harmony has its own cross-chain bridge Horizon that allows exchange of crypto assets between Ethereum, Binance Smart Chain and Harmony networks. There is also a beta version of a Harmony-Bitcoin bridge.
Harmony has numerous partnerships with various projects in the industry, the whole list can be found here. Some most notable partners include Chainlink, whose oracle service was integrated with Ethereum onto Harmony, and Matic which also allows for further interoperability between Harmony and Ethereum.
The Harmony team plans to focus on expanding the developer community and forging new partnerships. One of the team's main goals is to build a cross-chain ecosystem by bridging Bitcoin, Polkadot, Cosmos, and other popular blockchains.
Also, the team works on implementing zero-knowledge proof technology into blockchain. One of the already created products is ZkDAO, which will further increase decentralization by growing the validator community and putting network management in the hands of DAOs.
