Purchasing Harmony (ONE) with a Credit or Debit Card

Harmony is a Layer-2 blockchain designed to support decentralized applications (dApps) and cross-chain finance. Harmony focuses on improving speed and scalability through sharding, which splits the blockchain into multiple segments, potentially allowing for faster transaction processing.  

ONE is the native cryptocurrency of the Harmony ecosystem. It serves multiple purposes, including paying transaction fees, ensuring network security, and incentivizing participants. 

Harmony's native token is available on CEX.IO, a well-known cryptocurrency exchange that allows eligible enthusiasts to buy and sell crypto in the U.S. and over 200 other supported jurisdictions worldwide. 

In this article, we explore what ONE is, and how to obtain this token with a credit or debit card on CEX.IO, effortlessly and securely. 

About Harmony

Built on Ethereum (ETH), Harmony aims to improve upon some of the network's current limitations around transaction costs, scalability, and throughput. 

It uses a technique called Random State Sharding, which randomly assigns validators to shards to improve security and potentially prevent any single validator from having too much control.

To ensure fairness and unpredictability when selecting validators, Harmony uses a technology called VRF (Verifiable Random Function). This process ensures that validators are chosen randomly and cannot be tampered with.

However, it's vital to note that Harmony faces intense competition in its quest to tackle the existing challenges of building decentralized applications. 

Several similar “Ethereum-killers” share the goal of high scalability and efficiency for dApp communities such as:

  • Solana (SOL) – Like Harmony, this proof of stake (PoS) blockchain platform also utilizes sharding for scalability, and aims to offer comparatively fast transaction speeds and low fees.
  • Cardano (ADA) – Another PoS blockchain platform with a focus on scalability and security. It utilizes a unique Ouroboros consensus mechanism for efficient block validation, and prioritizes a research-driven approach to pursue secure, sustainable growth.
  • Avalanche (AVAX) – This high-throughput platform utilizes a novel consensus mechanism that combines proof of stake and Directed Acyclic Graph (DAG) technology. This approach to network structure potentially allows for faster transaction finality and improved scalability.
  • Polygon (MATIC) – This layer-2 Ethereum scaling solution works to improve scalability for dApps built on the base network. It utilizes various scaling techniques, such as sidechains and optimistic rollups, in an attempt to achieve faster transaction speeds and lower fees.

The role of ONE in the Harmony ecosystem

The primary function of ONE is as the native cryptocurrency of the Harmony blockchain. It acts like digital cash, allowing users to fund transactions on the network. This includes interacting with decentralized applications (dApps) built on Harmony or transferring funds between user accounts.

ONE also plays a crucial role in maintaining the health and security of Harmony's network by acting as a governance token, and incentivizing network participants through staking. 

Similar to the CEX.IO staking program, where participants can potentially earn crypto rewards by locking their cryptocurrency holdings, ONE holders can stake their tokens to participate in securing the network. 

By participating, network users become validators responsible for verifying transactions and adding new blocks to the blockchain. In return for staking, they earn rewards in the form of additional ONE tokens.

Disclaimer: Please note that ONE is currently not available for staking on CEX.IO. We encourage our customers to thoroughly research the available tokens for staking and understand the associated risks and rewards before engaging in this process. 

Staking involves committing assets, and it is important to make informed decisions based on reliable information and your financial situation.
