What is Harmony (ONE)?

Harmony, an open-source blockchain network, offers fast and cost-effective transactions, with support for cross-chain transfers. It emphasizes scalability through secure sharding while maintaining security and decentralization. Its mainnet has four shards with 1,000 nodes, enabling quick block times. Harmony’s native cryptocurrency, ONE, serves various roles, such as governance, staking, and transaction fee collection, supporting the ecosystem’s economic activities.

In this AAG academy article, we’ll explore Harmony and ONE in-depth, covering their functions and applications. We’ll examine the platform’s strengths, potential drawbacks, and address common queries to provide a comprehensive understanding of Harmony’s ecosystem.

What is Harmony

Harmony is an open-source blockchain network designed for fast, cost-effective transactions and diverse functionalities like digital asset exchange and secure identity management. It stands out by supporting cross-chain transfers involving major blockchains like Ethereum and Binance, promoting blockchain interoperability. Harmony prioritizes scalability as it aims to address the limitations of other blockchain networks.

One of its key innovations is secure sharding, a technique that enhances transaction throughput by dividing and managing blockchain data effectively. Harmony maintains a high level of security and decentralization while improving scalability through sharding. Its mainnet consists of four shards, each with 1,000 nodes, resulting in extremely fast block times of around two seconds. The platform also boasts a global node network managed by the Pangaea community, comprising roughly 800 of the 1,000 nodes and involving validators from over 100 countries, reinforcing Harmony’s commitment to decentralization and inclusivity.

What is ONE

ONE is Harmony’s native cryptocurrency, divisible into 18 decimal units, and plays a pivotal role in the platform’s economic system. It has diverse utility functions, including serving as a governance token, enabling users to participate in essential decisions, and staking ONE tokens to become validators, earning rewards. Additionally, ONE tokens are collected as transaction fees, facilitating economic transactions and supporting the platform’s growth.

ONE tokens have multifaceted utility within the Harmony ecosystem, acting as governance tools for community members to influence platform decisions. Users can also stake ONE tokens to become validators and earn rewards while contributing to network security. Moreover, ONE tokens are collected as transaction fees, ensuring the smooth flow of economic activities within the ecosystem.

How does Harmony (ONE) work

Harmony employs random state sharding, significantly enhancing scalability and transaction speed while ensuring efficient block generation. This sharding method divides the database into smaller, manageable segments known as shards, effectively reducing latency and enabling near-instant transactions. The use of a distributed randomness generation process in conjunction with an adaptive proof-of-stake (PoS) consensus mechanism empowers Harmony with security, scalability, and straightforward verification capabilities.

Harmony’s network benefits from the Fast Byzantine Fault Tolerance (FBFT) protocol, a variant of the BFT protocol. FBFT enhances the network’s speed and efficiency by enabling parallel transaction processing. By implementing aggregate signatures, Harmony effectively reduces communication overhead, allowing more than 250 validators to reach consensus in under two seconds, further improving the network’s performance.

Pros and Cons of Harmony

Investing, trading or engaging with the Harmony blockchain and ONE proposes a few pros and cons:


Decentralized Applications (DApps): Harmony is a noteworthy player in the world of DApps, enhancing blockchain infrastructure to provide faster and more reliable solutions.

Ambitious Project: Harmony is an ambitious project that aims to revolutionize the blockchain space with its innovative approach.
