What is One Harmony Coin

Harmony Technology

One Harmony Coin is the native token of Harmony Blockchain.

The Harmony Blokchain mainnet supports 4 different shards of 1000 nodes, which produces blocks in 2 seconds with finality.

Their community aims to build an open network of nodes, which operated and governed by a large community so called Pangaea.


Harmony One Coin Price Prediction


Harmony offers a different experience with various competitive edges:

  • Effective Proof-of-Stake (EPoS):
    • Harmony is Proof-of-Stake blockchain. The process of validator election is called Effective Proof-of-Stake (EPoS) which is the first sharding-focused PoS mechanism that prevents stake centralization.
    • In EPoS, validators with a large amount of staked tokens are obligated to run more nodes to support the network, while validators with less stake run fewer nodes where stakes are randomly and evenly distributed.
  • Fully Scalable Architecture
    • Harmony’s sharding works not only on the network transaction, or communication validation, but also on the blockchain state.
    • This feature makes Harmony fully scalable on all three aspects of the blockchain: network, storage and transaction processing.
  • Secure Random Sharding
    • The randomness used in the sharding is obtained with a distributed randomness generation algorithm (based on VRF and VDF).
    • Harmony re-shards the network in a non-interruptive manner using “Cuckoo Rule” to prevent against slowly adaptive byzantine adversaries.
  • Efficient and Fast Consensus
    • Harmony’s consensus algorithm is called Fast Byzantine Fault Tolerance or FBFT.
    • FBFT is a highly efficient and speedy consensus algorithm built upon the popular PBFT (Practical Byzantine Fault Tolerance) algorithm.
  • Scalable Networking Infrastructure
    • Harmony’s network layer is based on the industry-leading p2p protocol named libp2p.
    • To achieve high performance, Harmony adopts RaptorQ fountain code and use Adaptive Information Dispersal Algorithm to quickly and efficiently broadcast large blocks.
  • Asynchronous Cross-Shard Transactions
    • Harmony supports cross-shard transactions to achieve composability of assets and smart contracts between shards.
    • We designed a receipt-based asynchronous cross-shard communication mechanism which achieves eventual consistency so no double-spending is possible between shards.


One Harmony Coin

$ONE is the native token of the whole Harmony ecosystem in the standard of HRC-20.

The token has 18 decimals, with the smallest unit called Atto (~ 0.000000000000000001 ONE), and the second smallest unit is called Nano (~ 0.000000001 ONE)

$ONE token plays an important role that ensures the stability and security of Harmony network.

  • Pay for transaction fee
  • Stake to secure the network and earn reward
  • Open governance


Horizon Bridge

What is Harmony One Coin


This is a native bridge of Harmony which enables users to transfer tokens from Ethereum, or Binance Smart Chain to Harmony and vice versa.

Aside from the listed tokens, users can add a new token to the Horizon Bridge through a few steps.

You can find more information regarding the bridge on Harmony’s Docs.


Harmony One Dapps

Dapps on Harmony are growing quickly from DeFi to Gaming, NFT, DAO, etc. thanks to the development of Harmony SDK.

Harmony is now adopted by popular Ethereum Dapps as Sushi, Unifi Protocol, ViperSwap, etc.


Harmony One Coin Price Prediction

If the Harmony network keeps growing at this rate with more Dapps integrated,  more people will use $ONE to pay for transaction fees on Harmony.

It simply means the price will most likely go up in the long run.
