I. Project

1. Why is the project call "Harmony" ?

Harmony is the beautiful music when we sing in different notes but resonate. It’s analogous to our high-performance protocol of multiple shards but reaching consensus.Listen to our theme song “Teach the World to Sing In Perfect Harmony!”

2. What about Harmony project

Harmony is an open infrastructure, a high-throughput, low-latency, low-fee consensus platform designed to power decentralized economies in the future.

Their goal is to provide scalability and decentralization. The promise of blockchain is to allow decentralized coordination at scale but no platform can achieve both.

Harmony is built to aim to change that.Harmony implements a full stack approach to solving consensus at the scale level. Harmonyi applies innovations 10 times in every class in consensus algorithms, systems and networks to maximize network performance while maintaining hierarchy. Harmony's end-to-end integration allows for faster iterations and more robust optimization than the modular approach.

Through the consensus platform, their consensus protocol uses design principles such as shending and pipelining to parallel transaction processing. This allows them to effectively handle connection latency and allow their throughput to expand according to the size of the network.

II. Technology

1. Core Technical Innovations

Harmony is the highly scalable, minimal-fee and provably secure blockchain that will serves as the backbone of next-generation decentralized applications. Harmony innovates on both protocol and networking layers of blockchain by introducing:

- Highly scalable BFT consensus using BLS multi-signature.

- Secure distributed randomness generation protocol using VDF (Verifiable Delay Function).

- Adaptive PoS-based sharding mechanism guaranteeing the network security

- Kademlia routing and erasure encoding for optimal network usage

2. How is Harmony different from other public blockchain?

Unlike other pow systems, Harmony uses the pos mining algorithm. This algorithm provides users with high processing power and high security against attacks. Harmony consensus protocol has activated the system of adjustable block sizes to find solutions to the attacks occurring in existing blockchains. Blocks can be reduced to small sizes in order to prevent large whales who want to have a network with this system and which largely dominate their blockchains. In contrast to the Ethereum blockchain, there is no problem in the Harmony system as the number of users increases and the scalability of the blocks does not cause any unforeseeable problems. This system prevents the construction of new blocks on the missing and incorrect processes in the blockchains based on the logic of filling the free spaces on the computers. Each block can move independently and interact with other blocks.

III. Competitors

In late 2018 and early 2019, there are a lot of projects which aims to provide a new ecosystem for decentralized applications that is faster and cheaper than Ethereum. Some of them include Zilliqa, Kardia Chain, Harmony, Lighstreams, Solana, Jura, X-Block and so on. Most of them are still in the development stage, so comparing them is a bit hard as there are no clear indicators of real network performance. However, we can still compare other things.First of all, let's compare Harmony with several existing ecosystems which is already active (on mainnet). Who are they? Ethereum and Zilliqa. It is clear that Harmony aims to solve the problem of Ethereum, which is clearly indicated on their tech proposal. Ethereum doesn't use any sharding (yet) and they have limited TPS at this moment. Zilliqa on the other hand just finished their bootstrapping phase and is now looking to enter full mainnet. However, they're still young and it needs more real network performance to prove how strong their network will be. Harmony should be able to compete with Zilliqa, especially with their state sharding proposal which is claimed to provide better scaling solution than using transaction and network sharding only.So how about the other projects that are still on funding or early development stage such as Kardia, and so on? Most of them still don't offer any real usage yet. So the competition is pretty much open. It will depend on which project can deliver the highest scalability and also how many of them can acquire users / dapps on top of their platform. So I personally don't see any issue that limits Harmony from competing with their existing or future competitor. This is pretty much still an open space.

IV. Roadmap

V. Team

Very few teams have combined expertise in academic research, global-scale engineering, and long-term company building. And while that’s who we are, it’s our down-to-earth vision of a better world that drives us.

Their team members have built systems at the largest scale in the world’s top tech companies. They've worked on exciting projects at Google Maps, Apple Siri, and AWS Infrastructure—and now we’ve come together to build Harmony.

What is Harmony for me?

For myself, I have long concluded that this is a good project, the main thing in any project is the benefits for people. The project has very ambitious plans to conquer the market! So, you should spend a little time to research this project more closely through the links below:
