Harmony - is a low-cost consensus platform

Hello all of you . Welcome back to blogs. Today I will introduce you to a project that is highly appreciated. That is the Harmony project. As far as I know, this project is being invested by many investors. They have called for more than 18 million dollars. Here are the details so you can understand more about the project as well as if you want to invest

What is Harmony

Harmony is an open infrastructure for 10B people in the future. Harmony builds a high-performance consensus platform that will enable decentralized economies for everyone. Recent Harmony has earned $ 18 million in seed rings

Harmony is a fast and secure blockchain. Join a group of 12 people in Silicon Valley with 7 engineers from Google / Apple / Amazon and 2 doctors. Their public networks are active and completely open source. Important innovations of harmony are in deep protection (safe bet & reshaping with decentralized randomness) and in peer-to-peer networks (optimal cross-routing, rapid mass spread)

Target Harmony :

Harmony is providing scalability and decentralization. The promise of blockchain is to allow decentralized coordination at scale but no platform can achieve both. Harmony aims to change that.

Harmony believes in bringing value by first building a solid foundation on which people can build great blockchain products and use cases. To this end, They tried to focus on the core protocol, and are proud of our progress so far. At the same time, Harmony found that the core protocol under construction was just a base. Harmony's journey - into the vast wilderness blockchain - starts here,

Vision Harmony :

Today, only hundreds of thousands of people are participating in decentralized markets. Harmony wants to help millions of people participate in a completely fair economy. They believe that a scalable architecture and design of a public blockchain is critical to mainstream adoption and high-value use cases. Through the combination of innovations that have been studied in traffic networks, consensus protocols and system tools, Harmony thinks that the expanded blockchain protocol of Harmony can eventually support the market for billions of users.

Benefits of Harmony

Harmony helps businesses build marketplaces of fungible tokens (energy credits, security offerings) and non-fungible assets (game collectibles, real estate). Harmony developing zero-knowledge proofs for data sharing (ad exchanges, credit ratings) while preserving the consumer’s privacy.

Through a combination of innovations studied in traffic networks, consensus protocols and system tools, Harmony will support consensus protocols for billions of users.

Now Harmony has released testnet 2.0 (explorer) in April 2019 and has deployed core features including FBFT consensus, Cuckoo rule sharing, smart contract, canceled string structure revoke. Mainnet launched at the end of the second quarter / early Q3 of 2019.

Technical differences compared to existing projects:

Harmony is a state-based POS protection protocol, while current protocol projects are primarily based on POW. Consensus of Harmony is a fast BFT algorithm, using multiple sig BLS and linear scaling with number of nodes, while many existing projects use consensus based on old single strings (like Bitcoin) . The consensus of Harmony has no disc and is immediately finite, while the current sequence has a fork and does not have an immediate finite amount. Harmony provides a safe random source that can be demonstrated by the latest technology Verification Delay Function (VDF), ensures the security of segments and provides fair randomness for applications. . However, most existing security protection protocols are not protected by randomness, so it is vulnerabl

Harmony’s Foundational Node Operator Program

Harmony is an unauthorized protocol - anyone can join, leave and contribute to the network.

That said, it is equally important and practical to ensure that the protocol is secure from Day 1, and therefore the validation team needs to keep the protocol safe and stable. Therefore, Harmony has started the Founder button operator program to ensure that they will have an early community of external buttons / validators to help restart the network.

Harmony has kept the geographic diversity as an important criterion to welcome some early community / certification communities. Some areas are the Founding node operators from: United States, United Kingdom, Thailand, Russia, Taiwan, Canada, Czech Republic, China, Korea.

Launching Testnet & Staking Nodes

Harmony Testnet now has complete features for scalability. In the last few weeks, our engineers as well as external contributors worked relentlessly to deliver:

• Faster consensus using BLS multi-signatures & gossiping broadcast
• Node staking on beacon chain using smart contracts
• Secure resharding with Cuckoo Rule
• Robust peer discovery via libp2p bootnodes & Kademlia routing

Harmony will launch the mainnet in the coming months and there will be the following stages:

1. Token Transfer: genesis block, consensus with beacon chain, rate-limited transfer
2. Open Mining: node staking, block rewards, data aggregation
3. Open Governance: network resilience with 50% external nodes
4. Scalability: sharding with thousands of nodes, country-fencing for GDPR
5. Data Sharing: identity resolution & range queries via zero-knowledge proofs
6. Performance: fast routing, rateless erasure code, libunison, wasm

Controlling your own data must be a basic human right. Harmony will disrupt the centralized models like credit rating agencies or ad exchanges. Range queries, such as Do you have a net worth of $1M or more? Are you interested in a job offer with $200k salary in a Fortune 100?, now enable customers and business to interact with limited privacy exposure.

Open source for community and developers

Now Harmony is expanding its business model by having long-term relationships with developers to promote the project and they have developed two modes of sustained operations:

1. For developers:

Harmony has been open source since January 2019 and has more than 2,700 commitments with more than 100 stars from the community. They actively participate in the Harmony Discference forum discussions at talk.harmony.one and on Discord. In Q1 2019, Harmony also announced a $ 1 million technical bonus on Gitcoin to build a full set of developers. Tools with the goal of being the most accessible platform for developers to build .

2. For business:

Harmony has collaborated to develop organically to use replaceable token (energy credit, security service) and non-fungal assets (collectibles, real estate). Many of their partners are long-term friends and collaborators and have a close working relationship with them. Harmony is currently developing partnerships with asset use cases, stablecoin, energy credit transactions, game collection and advertising.

The importance of open source

Open source is also important to build an ecosystem. If we want others to use Harmony to create decentralized applications or build additional services that integrate with Harmony like wallets, they need to be able to look inside and see how it works. The source makes it easy for people to extend the protocol and create the entire ecosystem around it.

Features included:

Basic consensus protocol with O(n) complexity

Basic validator server

P2p network connection and unicast

Account model and support for Solidity

Simple wallet program

Mock beacon chain with static sharding

Information disposal algorithm using erasure encoding (to be integrated)

Blockchain explorer with performance report and transaction lookup

Transaction generator for loadtesting
