What is Harmony (ONE) blockchain and why it is getting so much traction?

Harmony is getting a lot of traction because it addresses core blockchain concerns, is energy-efficient, has cross-chain capabilities, offers lower gas fees and has a huge potential for nonfungible tokens (NFTs).

Maintain decentralization and security

Harmony thinks its network can scale while maintaining decentralization and security because it uses sharding, which divides validators into multiple groups and allows them to approve transactions and new blocks simultaneously. Harmony can now process 2,000 transactions per second (TPS), which is comparable to Visa, ONE of the world’s largest payment networks. Harmony believes it will process 10 million TPS in the long run.

On the other hand, Harmony does not compromise security or decentralization even as it scales. For example, the network assigns nodes or computers that join the network and validate transactions, to distinct shards via a distributed randomness generation mechanism. Harmony also keeps the minimum number of ONE tokens required for nodes to join the network as validators and preserve decentralization at a low level.


Many blockchain networks are now adopting the proof-of-stake model, which Harmony has employed since its inception. As a result, nodes put up existing tokens as collateral in this procedure to have a chance to be chosen at random to validate transactions. For a block to be approved, several validators must check transactions. Harmony stands out from other networks because its architecture and proof-of-stake consensus method allow it to complete blocks in under two seconds.

Cross-chain capabilities

Additionally, Harmony introduced Horizon, a cross-chain interoperability bridge with Ethereum, allowing assets to be exchanged between the two networks. This innovation can revolutionize cross-border payments and make cryptocurrency exchanges more convenient. Harmony has also established connections with other blockchains, such as Binance.

By allowing nodes on other blockchain networks to validate transactions, Harmony’s platform can transfer data across various blockchain networks, regardless of whether they use proof-of-stake or proof-of-work governance. 

Lower gas fees

Harmony’s network seldom becomes clogged, thanks to its high TPS and usage of proof-of-stake validation. As a result, it does not have high gas fees, which are now a fraction of a penny per transaction on Harmony. 

On the other hand, a network like Ethereum sees far more overall demand and transactions than Harmony. Still, Harmony claims that it can alleviate congestion issues by simply adding additional shards, even if the network is fully utilized and witnessing exceptionally high demand.

Huge potential for NFTs

The network’s cross-chain capabilities open up some exciting possibilities for NFTs, which are secure digital art, video and audio assets that may be transmitted on a blockchain network. Moreover, cheaper gas expenses may make the network appealing to developers interested in minting NFTs.

According to Harmony, bridging NFTs from ONE network to another may be costly at first, but subsequent transactions will be inexpensive. Harmony also announced on Twitter that it is working on NFT lending, NFT verification and fractionalization, among other features.
