About Harmony

What is Harmony?

Harmony is a blockchain and smart contract platform designed for decentralized applications, aiming to strike a balance between decentralization, scalability, and security. It uses multiple parallel blockchains (“state sharding”) to drastically reduce latency and produce new transaction blocks within seconds.

Our opinion

Harmony is a relatively new Layer-1 blockchain and a fresh competitor in the realm of smart contract platforms. What sets Harmony apart is its use of Random State Sharding, which essentially means executing network tasks in parallel to quickly produce new transaction blocks, thereby boosting efficiency. To maintain security in this setup, Harmony utilizes VRF (Verifiable Random Function) to ensure unpredictable, unbiased, verifiable, and immediate randomization, enabling a fair validation process. For its consensus mechanism, it relies on Effective Proof of Stake (EPoS), tailored to fit the sharding concept. Like all newer smart contract platforms, Harmony still has to prove itself, especially when it comes to solidifying its technological foundation. Currently, the most well-known project running on the Harmony blockchain is the blockchain game DeFi Kingdoms. Overall, the number of projects building on Harmony remains quite limited. We’re continuing to watch Harmony from the sidelines, but for now, investing in its cryptocurrency feels too risky for us.
