Origin and Development History
Background
Harmony was created by Harmony Protocol in 2019, aiming to solve scalability and security limitations in existing blockchain networks.
It emerged during the blockchain technology boom, with the goal of providing a fully scalable, secure, and decentralized infrastructure through innovative sharding technology.
Harmony's launch brought new possibilities to developers and enterprises seeking high-performance blockchain solutions.
Key Milestones
- 2019: Mainnet launch, achieving full sharding implementation including transaction confirmation, network communication, and blockchain state.
- Ongoing Development: Continuous optimization of Adaptive Information Dispersal Algorithm for cross-shard communication.
- Ecosystem Growth: Expansion in decentralized exchanges, gaming platforms, and IoT applications.
- Network Security: Implementation of DRG (Distributed Random Generation) process for unpredictable and fair shard validation.
With support from the Harmony community and development team, Harmony continues to optimize its technology, security, and real-world applications.
How Harmony Works
No Central Control
Harmony operates on a globally distributed decentralized computer network (nodes), free from bank or government control.
These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, granting users greater autonomy and enhancing network resilience.
Blockchain Core
Harmony's blockchain is a public, immutable digital ledger that records every transaction.
Transactions are grouped into blocks and linked through cryptographic hashing to form a secure chain.
Anyone can view the records, establishing trust without intermediaries.
Sharding technology further enhances performance by dividing the network into multiple shards that process transactions in parallel, enabling logarithmic scaling as the number of shards increases.
Ensuring Fairness
Harmony employs Proof of Stake (PoS) with optimized PBFT consensus mechanism to validate transactions and prevent fraud such as double-spending.
Validators maintain network security through token staking and block validation, earning ONE rewards.
Its innovation includes DRG-based shard randomization for unpredictable, fair, verifiable, and scalable validator selection, while ensuring small stakers can participate and preventing malicious actors from gaining control of single shards.
Secure Transactions
Harmony uses public-private key cryptography to protect transactions:
- Private keys (like secret passwords) are used to sign transactions
- Public keys (like account numbers) are used to verify ownership
This mechanism ensures fund security while transactions remain pseudonymous.
Atomic locking mechanism enables secure cross-shard transactions, maintaining consistency across shards through direct communication between shards via Kademlia routing.
Circulation Overview
As of January 19, 2026, Harmony (ONE) has a circulating supply of 14,823,972,008.76 tokens, with a total supply of 14,824,544,762.76 tokens. The circulation ratio stands at approximately 99.996%, indicating that nearly all issued tokens are currently in circulation. Harmony employs an inflationary model with no maximum supply cap (∞), allowing for continuous token issuance to support network operations and validator rewards.
Price Volatility
Harmony (ONE) reached its all-time high price of $0.37902 on October 26, 2021, driven by increased market interest in scalable blockchain solutions and broader cryptocurrency market momentum during that period. The token experienced its lowest recorded price of $0.00127355 on March 13, 2020, coinciding with broader market volatility and early-stage project development phases. These price movements reflect the dynamic nature of market sentiment, adoption patterns, and evolving perceptions of the project's technological capabilities.
