HARMONY : IMPROVING THE SHARDING SYSTEM

Introduction

Since the inception of Bitcoin in the year 2008, blockchain as a concept became known all over the world. Though decentralized money and its application is becoming well known in the world today, there is still a combat between the real and fake core bitcoin aspiration, this is so because in the cryptocurrency world today, there are so many imitators and wanna-bes choking the original Bitcoin aspiration to a corner. From the onset, Bitcoin was created as a peer-to-peer payment system, this system allows people to transact and transfer value without the help of a middleman. As time went on and as people began to invest into Bitcoin, its network began to overload and became unable to keep the pace thereby slowing overall performance and even more expensive.

About The Harmony Platform

Harmony is a decentralized sharding-based platform, backed by the blockchain technology to address the problems of so many blockchains. Harmony will solve these problems by merging autheticated research reports and also engineering practices in an optimally tuned system. Harmony has been proved and confirmed scalable, secure and energy efficient. Harmony proves to be the best in it consensus algorithm

What Is Sharding?

Sharding is a type of database partitioning that separates very large database into smaller, faster and more easily managed parts called data shards. It also means a small part of a whole.

Harmony breaks through in the following aspects:

Consistent Cross-Shard Transactions: Harmony uses an atomic locking mechanism to make sure of the constitency of cross-shard transactions, this means that Harmony supports a cross-shard transaction.

Secure Sharding: Due to the application of (DRG) distributed ramdomness generation, harmony sharding has been proven secure. The (DRG) can not be predicted, it is not bias, it is also verifiable and scalable. Harmony reshards the network in an irregular or discontinuous arrangement to prevent slow adaptive byzantine competitor.

Fully scalable : Harmony do not only shard the network interaction and transaction validation like zilliqa, it also shards the blockchain state, this is what makes Harmony a scalable blockchain.




Harmony Consensus Mechanism

The factor that cross-checks how secure and fast a blockchain is, is the consensus protocol.
The Consensus Protocols

1. The PoW ( Proof-of-Work): This powers Bitcoin, it is also a process that assigns miners to find a lasting solution to a cryptographic problem, the winner stands to get the right to choose the next block and by doing that gains more token rewards, as well as parallelize transaction processing

2. The PBFT ( Practical Byzantine Fault Tolerance): This protocol was researched and found for more than 20years in the academia, in the PBFT protocol one node is elected as the "leader" and the other nodes are the "validators". The consensus round involves two very important phase, the prepare phase and the commit phase.


The Shard Chain and The Beacon Chain

What is a shard chain?

The shard chain processes, validates and stores its own transaction and states. Shard only processes transaction that concerns it. Even though a shard is independent and works on its own it none the less communicates with other shard blockchains via cross-shard interaction.

Cross-shard communication: this is a vital ingredient of whatever sharding- based blockchain. The capability of cross-sharding removes every obstacle in between shard and spreads benefits of a single shard above itself. These are the 3 categories of a cross-shard communication :

Main-chain-driven: The Zilliqa project depends on the main chain to process transaction across shards.
Client driven: Omniledger has proposed a client-driven shard transaction mechanism whereby orders between shard are retrieved and sent to shards by the client.
Shard-driven: there is a proposal from the Rapidchain, that states that messages between shards are to be directly sent by nodes without the help of a third party.


The Beacon Chain

This is a special blockchain that is willing to serve added purposes when put in comparison with the other shard chains. the beacon chain can also be referred to as a shard, so to speak. Aside from processing transactions, beacon chain carries out the following funtions:

Generating random number &
Accepting stakes.
In the Beacon chain is a platform where stakers becomes validators by depositing their tokens.

Meet The Team




Conclusion

Harmony is a sharding platform that is secure, scalable and adresses challenges that the sharding sectors have been facing for a while now, harmony will be using consensus protocols to make sure to serve their users well, in harmony there will be no place for slow or delayed transaction, for they are working their fingers out to make sure to eradicate the era of delays and in-efficiency. Harmony will be making deepsharding easy and much more affordable.

Overview

Blockchain is making history by shifting power from centralized entities into the hands of the consumers. It has empowered people to manage their own assets without the intervention of any banks, brokers, or institutional monitors. This is a welcome necessity since people risk too much today by allowing their crypto assets to be controlled by a central entity. They don’t realize that it is not them but Wallets, Exchanges, & Lending Platforms that are controlling their assets. Hence, they have given up control of their identity, privacy, and money because they believe that they don’t have a choice. But not anymore. 

We aim to be the access point that provides people with this choice. BtcCredit is an all-in-one decentralized wallet which gives you complete control of your Blockchain asset to Hold, Exchange, Lend, Borrow, Invest, and Stake. This document outlines the design of a Decentralized Next-Gen Banking Ecosystem that is powered by decentralised multi-currency wallet, decentralised p2p lending, and decentralised p2p Exchange capabilitie

Market Analysis of P2P Lending

It is cited, that “According to Morgan Stanley, the market for Global Marketplace Lending may reach $290bn. by 2020, with an expected Compound Annual Growth Rate of 51% from 2014 to 2020.”

The BTC Credit team is trying to showcase the potential of this market, in order to explain that their truly innovative peer-to-peer wallet solution holds great potential. 

Fixing the Lending Market

Today the inflation-adjusted interest rate in different countries varies based on the available liquidity. In high liquidity market, Europe, interest rates are between 0.5-5 %, in Russia 12-15 %, in India 12 % and in Brazil 32 %. This shows a clear inequality in the way access to the lending market is distributed across the world. We believe that this inequality between the borrowers should be flattened and huge market value can be created in the process, especially through opportunities of Arbitrage. Banks charge 5-12% interest on loans and compensate you 0-1% for holding your assets with them. With the rise of crypto-currencies and Blockchain, you can now become your own banking institution. BtcCredit makes this a reality for you. Not just this, you decide whom you want to lend your money to, on which interest rate, and it what mode. All of this is available thanks to Blockchain technology, on which the Wallet of BtcCredit relies on.

Traditional P2P-Lending

Traditional P2P lending is similar to institutional lending, where some measure of credit history and creditworthiness of the borrower is taken into account. The creditworthiness of the borrower decides the type of loan deal he/she is offered. The method to calculate the risk/credit score is managed through proprietary algorithms/artificial intelligence. The differentiation is also maintained through how defaults are handled, and penalties are imposed.

Crypto P2P-Lending

There are some existing Crypto lending platforms which are following different business models. On one end they are a just like a traditional p2p lending platform with the ability to accept cryptocurrencies as collaterals. On the other end, they deploy the entire loan contract on the blockchain and execute events on the loan agreement through smart contracts. 

The blockchain technology, with its fully transparent and incorruptible transaction ledger, forms the ideal system for managing the loan with its parameters like tenure, interest rate, crypto collateral, etc. 

There are many platforms that offer crypto lending:

● Sofin 

● Everex 

● Ethlend 

● Lendoit 

● Btcpop

Competitive Analysis

P2P Lending Platforms can be divided into three main categories: 

1. Traditional P2P - Lending within the same country and in that country’s currency 

2. Cryptocurrency without Smart Contract - Lending globally with cryptocurrencies like Bitcoin 

3. Cryptocurrency using Smart Contract - Lending using Blockchain Smart Contract as an intermediate.

Notable Competitors

Lending Club (Traditional P2P) - Lending Club is a US peer-to-peer lending company, headquartered in San Francisco, California. It was the first peer-to-peer lender to register its offerings as securities with the Securities and Exchange Commission (SEC) and to offer loan trading on a secondary market. Lending Club operates an online lending platform that enables borrowers to obtain a loan and investors to purchase notes backed by payments made on them. Lending Club is the world's largest peer-to-peer lending platform.
The company claims that $15.98 billion in loans have originated through its platform up to December 31, 2015. BTCPOP (Cryptocurrency Loan without Smart Contract) - BTCPOP Ltd. was founded in 2014 and has developed into an established peer-to-peer lending site. BTCPOP's peer-to-peer lending is based on reputation and not on credit score. Users can get loans from other members or make money by lending - all by using Bitcoin. The BTCPOP solution doesn’t offer Smart Contracts.

ETHLend (Cryptocurrency Using Smart Contract) - A fully decentralized peer-to-peer lending platform using Smart Contract on Ethereum Blockchain for lending Ether by using tokens as a collateral. But ETHLend does not generate scores, nor does it offer any Compensation Fund to protect lenders. Lately, they have added a section to their WhitePaper about oracles and insurance, but it conflicts with their approach of using tokens as collateral, so the situation is unclear

SALT (Fiat Using Cryptocurrency as Collateral) – Centralized fiat currencies loan platform for loan amounts higher than $5000. It uses the Smart Contract only for depositing cryptocurrency as collateral. Their target market is borrowers with cryptocurrencies who do not want to liquidate their cryptocurrency into fiat currencies. Only accredited investors and qualified financial institutions can become lenders on SALT.

The Lender’s Pride

The Lender’s Pride platform proposes to enable a loan marketplace with some unique features. The system being proposed will form a forum for lenders and borrowers to check loan and loan request offerings including the loan parameters being offered. Based on their own risk perception ability to repay interest, the lenders and borrowers will “handshake” with each other to create a loan agreement on the blockchain.

How Does it Work?

As a lender, a user enters the system and funds his system generated Wallet with USDTs. The system creates a lending profile where his acceptable loan parameters are recorded. The lender's loan profile becomes a part of a “credit marketplace”. As a borrower, the user enters the system with his system generated Bitcoin wallet. The bitcoin funds in the wallet form the collateral against the potential loan. The borrowing requirement also becomes a part of the “credit marketplace”. A system internal logic automatically matches and suggests existing loans and borrowers. A borrower or lender can also manually select from a set of loan offerings or borrower's requirements. 

Once a loan is selected, and both sides agree to the parameters on the book, a “handshake” is said to have taken place, which will result in a deployment of a smart contract on the Ethereum network. The borrower's wallet will be funded with the requested USDT and a schedule for repayment gets created.

The repayment is recorded as the borrower deposits the instalment of USDT back into his WSDT wallet. A set of terms and conditions kick in in case the payment is delayed, is not enough or is more than required instalment.

Defining the BTC Credit Platform Keeping the competitors in mind and analyzing the market conditions and trends, BTC Credit has been able to identify 4 key verticals when it comes to the services offered by its Wallet: 

1. P2P Lending and Borrowing

2. P2P Crypto Exchange 

3. Handpicked ICO Investments 

4. Interests through Staking


All of these services will be offered with the help of a Wallet on the platform. Think of the platform as a Bank and the Wallet as a Bank Account. Analogous to the Banking System today, the user can load the Wallet with fiat or cryptocurrencies and use the funds to avail services in all the 4 verticals mentioned above.

Repayment Conditions

When the Contract is completed or in case of foreclosure the borrower's request for the return of their collateral of BTC deposited they can raise a request for BTC withdrawal and it can be completed. 

Normal repayments - The Admin Pays the Lender instalment regularly and the Borrower pays the Admin Regularly, the system will be notified by the blockchain of the next instalment date of the Borrower.

Instalment Delayed - If the Borrower Missed the date to Pay the instalment the API Interface will notify the Front-end of the Missing instalment of the Borrower. The borrower gets 3 days of grace period to pay the instalment. if the instalment is paid within 3 days no fine will be charged.

Instalment Delayed and Missed - If the Borrower missed the date of instalment he will be given 3 days of a grace period and even he misses to pay the Borrower will be fined for the particular instalment.

Borrower Defaulter - If the Borrower is unable to pay 3 consecutive instalments the system will be notified by the blockchain as the Borrower is Defaulter and the Front end can Confiscate its collateral.

Pre Closure Loan - If the borrower wants to Pre Close the contract he can close the Contract by paying the Principle + 5% Interest and close the contract but he can do only if he has paid 3 consecutive instalments

Extra instalment Payment - Here the instalment Amount is 1010 Every 30 Days, assuming the user deposits 1500 USDT/LTD and he is willing to pay more than the instalment Amount he can do it, but the next monthly instalment amount doesn't change its kind of foreclosure that meant the extra amount will be deducted from the last instalment, so if the amount is greater than the Last instalment then it will consider the Second Last and So on, if the Extra amount is greater than Last 3 instalment he has to either Pre close the entire contract or he can lower the Tenure till 3 instalment. 

IF the user is Doing foreclosure he can pay 5% Interest and Close the Contract by paying the remaining Principle and 5% interest.

Databloc Protecting the World's Data

Startup Origin in San Francisco is setting up a set of network protocols that allow developers and businesses to create decentralized marketplaces on Blockchain, with a focus on shared economies (sharing economy).

The Origin network protocol is a set of open source Blockchain structures for buyers and sellers in services such as Car-sharing (minute or hour rental) or Home-sharing (The feature of sharing photos, videos and music without sync) for trading on the open web is decentralized.
Applications of this protocol will directly store transaction data such as validity and pricing on Blockchain.

Origin recently released the Origin Protocol Demo DApp test, directly on Ethereum Network. They also announced that some companies have committed to developing additional applications on Origin floor.

“Our mission for Origin is to establish protocols that allow electronic markets to be governed by regulations instead of aggregating heads. We want to eliminate rent-seeking intermediaries, maximize personal freedom, reduce censorship and redistribute value to network participants, ”John Fraser, co-founder of Origin, spoke in a conversation with Bitcoin Magazine: “Partners are relying on Origin because they realize they can reach the market sooner and we can share the brand network application by co-operation. ”

Fix the problem of Centralized Marketplace

Uber and Airbnb, popular electronic markets for ride-sharing and home-sharing, often seen as people Play top in the booming sharing economy. Another noteworthy term is "People as a service," which describes the business forms of these two companies, where the attraction from the funding has priced both. The company is in the tens of billions of dollars.
Consumers are aware of Uber and Airbnb faster, cheaper, and better than comparable services to traditional services like taxis and hotels, which are transmitted through sophisticated applications that are easy to use. Although consumers are impressed with the purchase of direct applications from individual vendors in the decentralized model, peer network (P2P network), Uber and Airbnb are centralized, delivery systems. Translation between individual consumers and suppliers is guided through infrastructure, Hub networks and software belong to companies that own the exchange.

The centralized model makes Uber and Airbnb sensitive to control activities and it is likely that both services will be suppressed by the government at any time. Meanwhile, in addition to paying fees, owners of platforms that are fully in control of the network and individual providers are being condemned for exploitative behavior.

"Take Uber and Airbnb as a prime example," Fraser said. “Both companies are strictly controlled or even banned in cities around the world. The two companies have also banned some individuals permanently from operating in their markets.

Uber and Airbnb services lack Uber and Airbnb companies

According to figures provided by Origin, Uber, Airbnb and other centralized shared markets, it is expected to earn $ 40 billion per year from trading platform fees from now until 2022, and the platform The shared economy is generally expected to reach US $ 335 billion by 2025. Some sharing services are centralized 30% of the fee for organizing these transactions.
Origin wants to remove these intermediaries with new standards based on Blockchain technology.

Origin trading platform "allows people to freely trade on Blockchain technology in decentralized markets without having to go to an intermediary to search for benefits," said Coleman Maher, who recently joined Origin as You are in charge of long-term relations. "We aim to eliminate excessive transaction fees, reduce censorship and redistribute value to the community."
“We are envisioning a large set of virtual use cases (such as vacation rentals, freelance software engineers, rental tutors) that are considered Origin's leading standards and shared data. , ”Excerpted from the Origin product summary. Origin's applications will have user sharing features, creating a "shared network effect" that benefits all application providers and consumers.

DataBloc The First Enterprise-Grade Sharing Economy for Data Storage and Services

The creators present DataBloc, the main undertaking grade sharing economy for information stockpiling and administrations. The DataBloc stage is a web stage that flawlessly and safely interfaces specialist organizations and undertaking clients.

The DataBloc programming, otherwise called StoneFusion, will be a ninth era authorization based blockchain arrangement created by StoneFly, a settled
information administrations organization situated in Silicon Valley. The product underpins different information administrations and capacity types, and offers endeavor quality information streamlining, accessibility, availability, security, and insurance.

Specialist co-ops download StoneFusion and rundown their accessible administrations on the DataBloc web stage. Endeavor and open clients enter their capacity

necessities and which information administrations they require. Clients at that point select obliging suppliers from a curated rundown and buy benefits specifically on the web stage. DataBloc is the main arrangement where venture quality administration suppliers can download a product that enables them to sell abundance information stockpiling also, benefits over the web, without client procurement costs—all inside a secure blockchain system.

The measure of usable information is developing exponentially close by headways in Man-made consciousness, Social Networks, Machine Learning, and the Internet of Things. Shockingly, under half of all information stockpiling limit is being utilized. Brought together information specialist co-ops have wasteful organizations models and need security. Completely decentralized models improve security, however since anybody can act as a specialist co-op, clients need straightforwardness about who is holding their information, making critical selection contact. Be that as it may, a permissioned blockchain offers a legitimate center ground arrangement where clients profit by the security of the blockchain while keeping up straightforwardness about who is holding their information.

The present rendition of StoneFusion is being changed to a permissioned blockchain arrangement. Brilliant contracts on the Ethereum blockchain will oversee all exchanges on the DataBloc stage. Stone (ticker: STONE) is the utility token

used to purchase and sell benefits on the DataBloc stage. Eminence Bloc (ticker: RBC) is the security token that acquires a continuous eminence on the income created by the DataBloc stage. Both STONE and RBC are ERC-20 convention tokens and have a fixed supply. To raise development capital and disseminate the tokens, DataBloc is selling STONE in a private deal pursued by an open deal. After the STONE open deal, RBC will be sold in the first historically speaking Royalty Token Offering.
