View ChartHarmony (ONE) is an open-source, Layer-1 blockchain platform built to facilitate the creation and use of decentralized applications (DApps). The network is designed around random state sharding, a technique that divides the chain into smaller parts so transactions and data can be processed in parallel, allowing blocks to be produced in seconds. Harmony runs the Ethereum Virtual Machine (EVM), which means Ethereum applications can be deployed on its mainnet with 2-second transaction finality and fees described as 1000 times lower. The native protocol token, ONE, powers the entire economic system: it is used to pay transaction fees, stake for block rewards, and participate in governance. ONE has 18 decimals. Total supply figures reported across sources sit around 15.02 billion to 15.03 billion ONE, with circulating supply similarly cited near 15 billion. Harmony launched its mainnet in June 2019 and began staking in May 2020, and it remains an active EVM-compatible network focused on scalability and DeFi adoption.
Token allocation from total supply includes 22.4% for the initial seed sale, 12.5% for the additional Launchpad sale, 16.9% for the founding team and developers, 26.4% for protocol development, and 21.8% for the remaining allocation. The seed sale raised $18.3 million at $0.0065 per token in May 2018. A node round raised $5,500,000, headed by Binance Labs and HashKey Capital. The Initial Exchange Offering via Binance Launchpad raised $5 million at $0.003175 per token at the end of May 2019.
Harmony was founded in 2017 by Stephen Tse, who serves as Founder and CEO. Dr. Tse holds a Ph.D. from the University of Pennsylvania specializing in cryptographic protocols and type theory, interned as a researcher at Microsoft while finishing his degree, worked as a senior engineer at Google starting in 2006 for four years, founded Spotsetter in 2011 which was later acquired by Apple, and became a principal engineer for Apple in 2014. Co-founders include Rongjian Lan, who presented the Harmony technical whitepaper; Sahil Dewan; and Nick White. Leo Chen is a core team member. The founding team comprises twelve people, seven of whom are former employees of Google, Apple, Microsoft, and Amazon. The co-founders were all infrastructure engineers who previously worked for Google, Amazon, Apple, and Facebook, with experience spanning AI and machine learning, blockchain, VR, and compilers.
Harmony uses Proof of Stake through a mechanism called FBFT (Fast Byzantine Fault Tolerance), a proof-of-staking consensus based on a similar mechanism largely used in academia. On its consensus layer it applies Effective Proof of Stake (EPoS) to enable Sybil resilience. Random state sharding divides the chain into parts that execute transactions and store data in parallel. A Verifiable Random Function (VRF) is used for unbiased and unpredictable shard membership, so nodes and validators are assigned and re-assigned in a randomized manner. Erasure coding keeps the network fast and reliable. Under EPoS, members may stake directly or delegate holdings to an active validator in exchange for block rewards, and the design incentivizes delegation to smaller validators to lessen stake concentration. EPoS also includes incentive compounding, double-sign slashing to keep validators honest, and unavailability checking. The network presently supports a thousand nodes distributed across four shards that work together to generate new blocks every eight seconds with finality, meaning there is no threat of a competing fork. The project intends to create additional shards and support more nodes in the future.
Harmony's core differentiator is its focus on solving blockchain scalability through random state sharding combined with proof of stake. By splitting the chain into shards that process transactions and store data in parallel, Harmony aims to avoid the congestion problems faced by older networks. Its EVM compatibility means developers can bring Ethereum applications to a chain offering 2-second transaction finality and fees described as 1000 times lower. The network's use of a Verifiable Random Function for shard membership, erasure coding for reliability, and Effective Proof of Stake for Sybil resilience reflects an engineering-heavy approach. The project also emphasizes strengthening decentralization to accelerate DeFi adoption, and its Harmony Grants program is designed to support innovation and attract developers to the mainnet. With 640 of its 1,000 nodes maintained by community members, Harmony has cultivated a participatory node community alongside its technical design.
ONE is the native token supporting the monetary flow of the entire Harmony economic system. Users must pay a small transaction fee in ONE to access the network, making it the unit of account for on-chain activity. Token holders can stake ONE on the network in exchange for block rewards, either by staking directly or by delegating holdings to an active validator. ONE also carries voting and governance rights, allowing holders to participate in decisions about the network. More broadly, the token incentivizes and rewards a wide range of participants, including developers, validators and stakers, investors, and community members who build, secure, and govern the network. Harmony leverages blockchain to align the incentives of stakeholders, developers, and businesses while enabling them to construct open markets for fungible and non-fungible tokens and assets.
Harmony is positioned as most beneficial for developing DApps and solutions capable of powering the construction of DApps, providing a highly scalable service with swift and efficient transactions. The project created Effective Proof of Stake on its consensus layer to enable Sybil resilience, and its Harmony Grants program aims to support innovation and attract developers to the mainnet. According to the project's website, Harmony was expected to introduce cross-shard contracts and a cross-chain infrastructure by the end of 2021, and in 2020 the team hoped to achieve cross-border usefulness, decentralized development, and auditable privacy. The network's node footprint reflects an evolving ecosystem: of 1,000 nodes, 640 are maintained by community members, while the Harmony Foundation looks after the remaining nodes without receiving staking payments. The team wants to offer the remaining node slots to the community as the network evolves. The platform focuses on strengthening decentralization to accelerate the ecosystem's DeFi adoption.
Harmony does not use proof-of-work mining. Instead, network security and block production are handled through Proof of Stake via FBFT and Effective Proof of Stake. Participants acquire ONE and either stake it directly or delegate it to an active validator in exchange for block rewards. EPoS includes incentive compounding, double-sign slashing to keep validators honest, and unavailability checking. The design incentivizes users to delegate to smaller validators, aiming to lessen stake concentration. Staking on Harmony began in May 2020. Because rewards depend on validator performance and network conditions, participants should review validator metrics and understand slashing and unavailability rules before committing tokens. Running a node or choosing a reliable validator are the primary ways to participate in securing the network and earning rewards.
Harmony ONE holders should follow standard self-custody practices. Store tokens in a wallet where you control the private keys, and never share seed phrases or private keys with anyone. When staking, verify validator identity and track record, and be aware that EPoS includes double-sign slashing and unavailability checking, so validator misbehavior or downtime can affect returns. Because ONE is an EVM-compatible asset, be cautious when interacting with smart contracts and DApps, and confirm contract addresses before approving transactions. Keep software and wallet firmware up to date, use hardware wallets for significant holdings, and consider splitting assets across multiple wallets to reduce single points of failure. The August 2026 exploit, in which an attacker unauthorizedly minted approximately 4 billion ONE tokens through a consensus-layer bug, illustrates that risks can originate at the protocol level rather than only from user error, so staying informed about network incidents and official communications is part of a sound security routine.

Harmony (ONE) secures its network through Effective Proof-of-Stake (EPoS), a variant of Proof-of-Stake that lets holders stake ONE directly or delegate to an active validator in exchange for block rewards. EPoS uses the Verifiable Random Function (VRF) to assign and re-assign nodes across shards in a randomized way, and it actively incentivizes delegation to smaller validators to reduce stake concentration. It also includes double-sign slashing and unavailability checking to keep validators honest. Staking began in May 2020.
On the supply side, annual issuance is set at 441 million ONE tokens and declines over time, which holders often describe as deflationary tokenomics. Because new issuance adds to circulating supply, sustained demand from staking, transaction fees and governance use is what determines whether ONE's long-term price absorbs that inflation. If network usage grows faster than issuance, the dilution effect weakens; if not, new supply can pressure the price.
Harmony (ONE) runs the Ethereum Virtual Machine (EVM) on top of a sharded architecture, so developers can port Ethereum applications to a faster, cheaper environment. The network currently supports around 1,000 nodes across four shards, producing blocks roughly every eight seconds with finality, which keeps transaction fees low compared with congested Layer-1 chains.
Low gas fees matter for ONE demand because cheaper transactions encourage more DeFi, DApp and NFT activity, and every interaction still requires ONE for fees and staking. The Harmony Grants program is designed to attract developers to the mainnet, and the project has targeted cross-shard contracts and cross-chain infrastructure to deepen its ecosystem. As TVL and on-chain usage expand, more ONE gets locked in staking and contracts, tightening circulating supply. That combination of higher utility and reduced float is the main channel through which upgrades can support ONE's value.
A spot ETF would be a regulated fund that holds Harmony (ONE) directly and issues shares that trade on traditional stock exchanges. That structure lets institutions and brokerage clients gain ONE exposure without managing wallets, private keys or exchange accounts themselves.
For ONE, sustained institutional inflows would likely improve liquidity, tighten spreads and add a steadier layer of demand alongside retail trading. Greater institutional participation also tends to raise legitimacy and can create a firmer price floor, because large holders often treat the asset as a longer-term allocation rather than a short-term trade. That said, ETF approval and adoption depend on regulatory decisions and on the maturity of ONE's market. Any inflow effect is gradual and does not remove the volatility that comes with a smaller-cap Layer-1 asset.
Harmony (ONE) and Ethereum both run the EVM, but they scale differently. ONE uses state sharding and Effective Proof-of-Stake to split nodes and blockchain state into parallel shards, targeting fast finality and low fees. Ethereum relies on a single execution layer plus Layer-2 rollups for scaling. The comparison below summarizes the key differences.
| Dimension | Harmony (ONE) | Ethereum (ETH) |
|---|---|---|
| Core Positioning | Sharded EVM Layer-1 for fast, cheap DApps | Largest smart-contract settlement layer |
| Supply Model | Annual issuance of 441M ONE, declining | Fixed issuance plus EIP-1559 burn |
| Consensus | Effective Proof-of-Stake with VRF sharding | Proof-of-Stake with L2 scaling |
| Main Use Cases | DeFi, DApps, micro-payments, NFTs | DeFi, stablecoins, L2 rollups, NFTs |
For ONE, the value question is whether sharding speed and low fees translate into real usage and fee demand. Faster, cheaper blocks can attract developers, but they only lift ONE's price if activity and staking lock-up grow enough to offset issuance.
On BTCC, you can attach stop-loss (SL) and take-profit (TP) orders to any ONE/USDT perpetual contract position. The logic differs for longs and shorts:
You can also use a trailing stop, which automatically follows the price as it moves in your favor. This lets you lock in profits and, once the trade is safely in profit, move your stop-loss up to break-even so a reversal cannot turn a winner into a loser. Always size the position so the distance to your stop-loss matches the risk you are willing to take.
The current price of Harmony (ONE) is $0.002429, with a market cap of $37.897594M and 24h trading volume of $39.735112M. The circulating supply is 15.03B (max supply ∞).
Because ONE trades around the clock across many venues, these figures move continuously. For the most accurate live numbers, check the ONE/USDT perpetual contract page on BTCC, where you can also view the live order book, recent trades, funding rate and open interest before placing an order.
Harmony (ONE) is influenced by three layers of drivers:
Security events matter too: the 2022 Horizon Bridge hack and the 2026 unauthorized minting incident both hit ONE's price sharply, showing how sensitive the market is to supply and trust shocks.
The all-time high of Harmony (ONE) is $0.379832, reached on 2021-10-26 09:20; the all-time low is $0.000232, recorded on 2026-08-12 22:35.
Comparing the two extremes shows how volatile ONE has been across its full market cycle, from the 2021 bull market peak to the lows that followed later supply and security shocks. For a complete view, open the ONE/USDT chart on BTCC and inspect the full-cycle candlestick history, including volume and moving averages, before making any trading decision.
Reading ONE candlesticks starts with the anatomy of each candle:
Combine these signals on the ONE/USDT chart on BTCC rather than relying on any single indicator.
You do not need to hold spot ONE to profit from a falling price. On BTCC you can short ONE/USDT perpetual contracts: open a short position at a higher price, then close it (buy back) at a lower price to lock in the price difference as profit.
This gives you two-way trading opportunity. In a bear market or during a pullback, a short position can generate gains while long-only holders wait for a recovery. Because perpetual contracts also support leverage, the same price move can produce a larger percentage return, but losses are magnified in the same way. Always pair a short with a stop-loss above your entry and consider a take-profit near a support zone where price may bounce.
Yes. BTCC offers flexible leverage on ONE/USDT perpetual contracts, up to 50x, subject to the platform's risk rules and position limits.
Leverage magnifies both gains and losses: a small adverse move can wipe out a large share of your margin, and liquidations can happen quickly in volatile markets. Beginners should start at 2x to 10x and always attach a strict stop-loss before entering. As you gain experience and a consistent process, you can adjust leverage to match your risk tolerance and the volatility of ONE at that moment. Never risk more margin than you can afford to lose on a single trade.
After registering on BTCC, you can switch to Demo Trading mode and receive virtual funds, such as 100,000 USDT, to practice without risking real money. The demo environment uses real ONE market data, so prices, candles and order books behave like the live market.
Use it to rehearse the full workflow: adjusting leverage, placing market and limit orders, setting take-profit and stop-loss levels, and testing a trailing stop. You can also practice position sizing and see how quickly a leveraged ONE position reacts to volatility. Once your process feels consistent, you can move to live trading with real funds and the same order tools.
Follow these four steps to buy and trade Harmony (ONE) on BTCC:
Start with a small position and low leverage while you learn how ONE moves, and use the demo account first if you are new to futures. Always confirm your SL/TP before submitting, since ONE can be highly volatile.
