Harmony vs IOTA

General

Description

Harmony Logo
Harmony
 (ONE)

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 Logo
Harmony
 (ONE)
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.

IOTA Logo
IOTA
 (IOTA)
IOTA underwent one of the most dramatic transformations in crypto: After years developing its own Tangle technology, the project made a radical pivot to the Move Virtual Machine in 2024. While the original vision of a fee-free machine economy was innovative, the DAG-based approach failed due to practical issues like the never-removed Coordinator and performance weaknesses. The move to Move represents both capitulation and fresh start: IOTA now uses proven blockchain technology instead of experimental approaches. The project maintains its IoT focus but must regain trust from a divided community and compete against established Move chains like Sui and Aptos. IOTA's industry partnerships and domain expertise remain valuable, yet the entire ecosystem must be rebuilt from scratch. For investors, IOTA is now a completely different project than before – less visionary but potentially more realistic. We follow the development with interest but currently don't recommend investment due to high uncertainties and strong competition. IOTA's story shows: Even innovative ideas can fail, but the courage for radical realignment deserves respect.
