Analysis of Zichain, a blockchain digital financial solution

Bitcoin’s popularity has grown exponentially since 2009 and reached its highest point anywhere in the world in 2017. The topic of blockchain and cryptocurrencies has become one of the most talked about, far beyond the closed ecology of the IT world. Although cryptocurrencies have attracted high government attention, only a tiny minority (0.5% of the world's population) utilize blockchain technology. The main limiting factor in the popularity of cryptocurrencies is the complex infrastructure, which is inconvenient and sometimes confusing for users. Combining our successful long-term experience in asset management and an excellent technical team, we decided to create a set of convenient independent modules for private and institutional users who wish to invest in the cryptocurrency market.

Blockchain technology is based on the fundamental principle of decentralization, which can eliminate middlemen, such as banks and other financial institutions, when performing various transactions. Nonetheless, even if cryptocurrencies are in excessive demand, there is no example of any development in the industry today. Even though dozens of highly specialized companies are developing solutions to enter the cryptocurrency market, investors are still unable to act without a reliable central counterparty.

The existing infrastructure of the traditional financial world provides a complete picture of our business. First, it is important to provide a source of relevant and reliable information about market happenings in a convenient manner. The amount of information in the world doubles every two years, so data that is prioritized for analysis and categorization by specific criteria becomes increasingly valuable. Most of the existing information portals do not meet the basic requirements of investors in terms of the relevance and content of the information. Therefore, we see the need to build a new infrastructure to collect and analyze industry news and market data, based on which custom analytical products will be created. Based on feedback from our research reports, our multilingual information and news portal will address existing issues for market participants and will benefit the entire crypto investment community.

There are two absolute values ​​in the cryptocurrency ecosystem. These are the market cap of Bitcoin and the market cap of the rest of the market. Almost everyone knows about Bitcoin, while the vast majority of the rest of the cryptocurrencies go almost unnoticed. Market participants need to spend a lot of time and resources to understand the main characteristics of each blockchain project to greatly reduce investment risks. We provide systematic solutions for cryptocurrency information. We took the best practices of the traditional financial world, brought in S&P S&P, MSCI, MSCI, FTSE, EuroStoxx, and Nikkei and created a range of indices that The index divides the cryptocurrency ecosystem into several parts, but together they form a whole. The first level index is called Blue Coins, the second level Second TIer. In the index of currencies, services and platforms, we include cryptocurrencies that reflect the essence of each specific segment. Additionally, we detail the most important and largest projects and give them characteristics in our Crypto-wiki. The news flow related to the index and Crypto-wiki forms our CryptoEYE information and analysis module.

Many industry investors believe in the blockchain and cryptocurrency market in terms of their ideas and technological potential, and expect to grow exponentially in the medium term. Based on traditional currency investment practices with fundamentally attractive assets, a “buy and hold” strategy is the most beneficial in terms of reward-to-risk ratios. In the cryptocurrency industry, most of which are projects built by startups, this strategy is difficult to implement without index investing. In this context, the rational way to invest passively is to invest in an index that operates on a well-known methodology that includes/excludes issuers based on changing market conditions. We have found that additional value to investors can be created by managers in various index combinations based on the client's risk profile and preferences. To meet these needs and market demands, we established TheIndex.Fund, which will play an important role in developing passive investment strategies for long-term investors.

Our research on the crypto market and feedback from a large number of successful investors and talented entrepreneurs shows that the flow of people reallocating real capital in cryptocurrencies is increasing significantly. The main hurdle currently facing seasoned potential investors is an imperfect asset management infrastructure. Today, there is no convenient, reliable and safe way to place funds under the governance of the cryptocurrency market. In the traditional financial industry, each counterparty performs its functions independently: managers make investment decisions; fund managers calculate unit value, are responsible for the safety of funds, and keep investor registration information; auditors check fund accounts. In the cryptocurrency world, all these functions are centralized - the corporate creator of the fund is in charge of all of them. In this case, the transparency of the fund, the reliability of data and the safety of investors' assets cannot be guaranteed. Our Fund Management Module (Blockchain Asset Management Platform - BAMP) was developed to address and minimize these risks and to make the crypto asset management industry safe and transparent. The fastest growing asset management sector in the world in 2018, and we believe this trend can be successfully replicated in the cryptocurrency world.

In addition to passive index strategies, there are plenty of good managers willing to offer investors alternative investment strategies that may outperform the market. For such managers, the most important factors besides strategy are the existence of convenient infrastructure and the possibility of asset growth under management. Our BAMP product provides all infrastructure functions, replacing administrators, management companies and auditors, while CryptoEYE exposes trading strategies to a wide range of investors. Solving many of the current cryptocurrency industry issues with one product, Zichain enables the new digital economy to reach a new level by enabling many executives to implement their strategies and attract large numbers of investors to the industry.

A complete set of modules

1. Fund management module Blockchain AssetManagement Platform

Currently, there are dozens of investment funds in the cryptocurrency industry whose infrastructure cannot be called reliable and whose asset management process cannot be considered transparent. Although the industry is in the early stages of development, several large-scale thefts of investor funds have occurred. With much of the money operating outside the legal framework, national institutions around the world recognize the need for a systematic approach to regulating the cryptocurrency market. Sooner or later, market participants and asset managers will demand changes to their operations to minimize their exposure, especially counterparty risk.

BAMP is a platform that foresees this future need, providing a ready-made technology solution for creating and managing investment funds. It also provides all the necessary tools to monitor the condition of an investor's portfolio, while meeting all the usual standards of traditional financial markets. An important feature of the platform is an automatic guarantor between the investor and the manager. Our infrastructure allows its users to create transparent investment policy statements (IPS) in the blockchain. With access to the platform and its infrastructure, many executives will have the opportunity to implement their own investment strategies, thereby continuously attracting new investors. All necessary functions such as execution of trade orders, back office functions, risk management, compliance and accounting - are implemented within the BAMP platform. The only thing required to implement a successful investment strategy is a manager and his related talents. Therefore, this module complies with all the practices generally accepted in traditional financial markets.

Token Issuance

When creating an investment strategy, the platform deploys a smart contract (ERC20) in the Ethereum blockchain for token issuance.

The first investors bought the fund tokens at 1 TKN = 1 USD. Each subsequent investor will purchase tokens at the price in effect at the time of purchase, subject to an assessment of the market value of the fund's assets. When token redemption becomes possible, the investor should return the tokens to the smart contract and receive the receivable portion of the funds on the wallet.

There are two signatories in a smart contract: the platform and the manager. Each investment strategy loads a new smart contract (ERC20) in the blockchain. Smart contracts have the functions of token issuance, distribution, refund and transfer.

Investors' funds are kept in corresponding multi-signature wallets. Three keys are used for multisignature: investor, manager and platform key. Investors and managers' keys are stored on the wallet's local computer as a web extension, using the RPC protocol to provide restricted platform management.

The platform generates the platform wallet, which is included in the IPS, at the beginning of the investment cycle of each cryptocurrency.

Manager wallets are generated by managers using a web browser extension. The platform replicates wallet addresses to generate multi-signatures.

Investor wallets are generated by investors using a web browser extension. The platform replicates wallet addresses to generate multi-signatures.

To execute any transaction from a multi-signature wallet, at least two signatures are required.

web extension

Web extensions for Google Chrome and Brave will be created for investors and executives. This expansion will make wallets generated from the list into corresponding investment strategies (available both online and offline) and transfer all wallet addresses to the platform to create a mulTIsig.

Investors can use the browser extension to view a list of selected strategies and the balances of the corresponding cryptocurrency wallets. )

Managers can use the browser extension to view the IPS-generated strategy list, investor list and their wallet balances.

Investors and managers can sign all multi-wallet transactions by using a button in the web extension.

invest

To make an investment, potential investors should register and verify on the website. After completing this process, investors will see a list of available strategies in their personal account.

He can then choose a strategy and generate a wallet address with the cryptocurrencies listed in the IPS. Funds should be transferred to an Ethereum wallet that has been generated in the browser extension, then create a multi-wallet.

The investment amount is based on the dollar value of the cryptocurrency transferred by the investor. The number of tokens an investor must receive depends on the weighted average exchange rate during the portfolio construction period. For example, if a manager takes 12 hours to buy a large amount of cryptocurrencies, the exchange rate may vary greatly, and the number of tokens in the portfolio is unknown until the portfolio is completed (this number may be higher or lower at the time of the transfer of funds) than expected).

financial calculation

Calculate the exchange rate

In order to calculate the profit and price of the strategy token, the average exchange rate of the cryptocurrency is applied to all transactions specified from the IPS and used by the manager to rebalance the portfolio. If the cryptocurrency is not traded in USD, the cross rate via Bitcoin is used in the calculation.

Profit Distribution

Profit is the difference between the investment amount and the IPS's portfolio value at the end of the performance fee (PF) calculation period. If at the end of the previous PF calculation period, the portfolio value exceeds the investment amount, all funds are considered to be invested in the strategy after deducting the management fee (MF% - annual management fee) during the current period. MF is paid to the manager according to the schedule set out in the IPS and is calculated according to the following algorithm: 1/365th of the MF% of the portfolio is reserved per day (1/366th in leap years). The reserved amount is sent to the manager's personal wallet according to the schedule specified in the IPS. The minimum expected return on capital (HR%) is the minimum threshold for a portfolio's value growth in the current year below which managers are not rewarded for successful investments. If the value of the portfolio increases by more than Human Capital %, then the PF% increment minus the minimum expected capital return is paid to the manager and the rest to the investor. PF is paid to managers when calculating profits. In addition to MF and PF, managers should also receive an entry fee (EF%) and an exit fee (ExF%) when investors enter and exit the market, respectively.

Token price

The first investor's token price is allocated $1. Furthermore, it is directly dependent on the portfolio value and does not include fees paid to managers at the end of the period. The token price is calculated according to the following formula:

Portfolio Value

Portfolio value is the total value of all cryptocurrencies (USD) under management during the current investment cycle.

Portfolio Value Calculation

Portfolio value is calculated as the total value of all cryptocurrencies within the strategy, excluding funds used to pay Performance Fee (PF) and the Daily Partial Management Fee (MF).

virtual currency withdrawal

A manager can transfer portfolio funds to his or her trading sub-account for portfolio rebalancing or active trading. The maximum withdrawal amount is specified in the IPS as a percentage of the total portfolio value (in USD).

The platform checks IPS compliance and signs withdrawal transactions. The manager also signs the transaction and initiates the funds transfer process.

2. Trading Terminal

Thanks to the development of e-commerce online trading, buying and selling currencies, stocks, bonds and other securities has become so easy, all a trader needs to do is register an account with a broker and press a button to execute the trade. The current market infrastructure allows you to invest in most assets without any barriers, with low fees and an acceptable, transparent price. However, it is difficult to execute large trades in a short period of time without significant market impact. Institutional traders, such as investment or pension funds, banks, insurance companies or OTC brokers, often encounter these types of problems. In the cryptocurrency industry, institutional trading issues are more prominent due to relatively low liquidity and market segmentation.

The Zichain trading terminal provides a mature multi-functional trading platform that allows traders to buy and sell cryptocurrencies 24/7 from anywhere in the world and on any exchange. The trading terminal also includes a set of professional tools for portfolio management, such as using smart order routing or using advanced execution algorithms:

3. Fiat gateway ZiChange

Blockchain is an ideal solution for making payments, banking transactions, currency exchanges, and other operations that are vulnerable to fraud or disclosure of confidential information when processed by existing systems. Blockchain technology is developing rapidly, which is attracting many different players, from ordinary consumers to hedge funds. Eighteen major cryptocurrency exchanges in the U.S., Europe, China, Japan, and South Korea have an average daily trading volume of about $15 billion. The ratio of market participants' activity to market capitalization is at least as high as the U.S. stock market. As more and more investors flood the market, they all have one thing in common: the need for a unified platform that acts as a legitimate access point to the crypto world and offers high liquidity and transparent transaction costs.

Currently, one of the main obstacles to the development of the cryptocurrency market is the complex process of exchanging fiat currency into crypto assets and vice versa. Services such as exchanges, trading platforms, exchange facilities and payment systems are commissions that may vary significantly.

We believe that there are three major issues preventing retail and institutional investors from entering the crypto asset market:

• Lack of trusted counterparties

• Lack of transparency

• Lack of liquidity

The goal of Zichange is to create a brokerage module that bridges the gap between the traditional world of finance and the developing world of crypto. We will provide retail and institutional investors with a completely legal and transparent solution for converting fiat currency to crypto assets. Our main input to the market will be a combination of the accepted operational standards of the traditional financial industry and the values ​​that drive the development of blockchain technology (such as simplicity, convenience and security). ZiChange will remove the barriers that institutional and retail investors face when entering the crypto asset space.

There are two transaction services:

• Fiat and cryptocurrency exchange services. The company will provide a legal and secure entry into the cryptocurrency market. All transactions will comply with regulatory requirements.

• Encryption and encryption exchange services. The company offers a variety of crypto assets on a mobile platform.

Main features of ZiChange:

• P2P-like transactions - 100% of client assets are stored in their wallets, eliminating counterparty risk.

• Single entry point - access all markets through a single partner

• High liquidity - ideal for large trades

• Preferential Rates – Due to the advanced order system and execution system, the best price regardless of transaction size.

Data collection and storage subsystems and "Big Data Crypto Analysis" provide information requirements for obtaining, systematizing, classifying, storing, and comprehensive analysis of encrypted ecosystem data.

Subsystem structure

Hardware and software requirements

The CryptoEYE data collection and storage subsystem consists of a data collection module and a DBMS; they can be located on the same or different servers. The following are the requirements for a dual server implementation.

Description of the data collection process

a. Data Collection Device (Data Collection Assembly)

b. Load Balancing Proxy Server

Balanced proxies are used to anonymously process some of the requests performed by websites to reduce the likelihood that they will block our requests. It offers to use an nginx based proxy server. It is recommended to use an external http(s) proxy with a static IP.

c. Web crawler distributed computing cluster

A web crawler is a program that scans and processes web pages in order to write the required information into a database. The distributed computing cluster application consists of the crawler main program and a set of data source crawler written in Node.js. From a technical point of view, the main program checks the folder containing the web crawler module, creates child processes using the spawn method, and passes the module name as a command parameter to these programs.

On startup, ipc is specified as one of the stdio channels. This enables the main process to receive messages via the child.on('message', function(message){...}) handler and send messages using the child.send(message) method, which can also be called in the child process ('message', function(message){...}) and process.send(message) methods.

It is recommended to send JSON objects as messages. The main function of the crawler is to handle requests from child processes, for which it has 2 queue groups) The first queue group is the pageview queue. Create an in-memory array of page load tasks for each submodule. A page load task is an object consisting of the URL of the desired page and a feedback function that sends data to the child process. The pageview queue is handled by multiple loading streams, each of which selects the upper-level task in the array and loads it, and when the loading is complete, calls the feedback function, passing it the load data block as a parameter. The task appears in the queue via an ipc link with a child.on('message' function(message){...}) process and writes to the end of the queue. After the queue is exhausted, a drain message is sent to its child process, which is one of the signals that the current website loading iteration is exhausted. However, the decision to load the website is done by the child process, so it may process the page as messages arrive and create other tasks separately for the main process.

The second queue group is the object storage queue. Each child process redirects it to the main process via ipc while finding and logging the records it needs to export into the database. The main process puts all received records into a storage queue, each record corresponding to a table in the database. Then use the pooled connection to select a certain number of records (currently 50), make the request and the corresponding bind variables, and send the data to the database. The database is restarted as soon as a response arrives, or after a timeout if there are not enough records in the queue.

Subprocess functions include: processing each page received from the main process, analyzing all URLs for that page, filtering relevant links, creating new tasks to load web pages to write items to the database.

Website load planning starts with starting the home page task. Tasks are transferred to the main process, and responses to them will generate new links and may need to store data. If any data needed to be stored in the database is found on the page, the data logging task will be created in JSON format and sent to the main process.

Each crawler must control the start and end of website loading. Each child process has a body object to track the actions of the page. If an emit signal is received from the main process, the crawler checks to see if all pages have been processed. If everything is processed, the crawler will sleep, i.e. set a timeout to initialize the website load.

If an emit signal is received from the main process, the crawler checks to see if all pages have been processed. If everything is processed, the crawler will sleep, i.e. set a timeout to initialize the website load.

It is critical to create the mask and build the algorithm that determines the type of data source:

I. The page has all the necessary data to be extracted.

II. The page contains links to I. Types.

III. Pages not related to the purpose of data extraction, not related to Category I or Category II pages.

d. Scrapy type network data collection module

Framework information is available at http://scrapy.org/. Some websites do not provide data export or API services. To solve this problem, we built an independent uploading module that recognizes the HTML code of a web page, analyzes its content and extracts the necessary data. Metadata for item and page content is sent to the data processing pipeline. For this we use the following set of processors:

1. Debug handler that writes data to a file

2. A data validation processor that rejects inapplicable or insufficient data items (Reddit, Twitter, and other broad sources only)

3. Upload submit processor (json - rpc).

database

The database contains tables of raw data collected by the crawler (one table per source) as well as tables of aggregated data generated by the processor. Raw data tables are divided into data sources. Table inheritance in Postgres ensures data consistency. . The database also contains aggregated data tables containing standardized information from all sources in the following format:

● Date

● Author

● Title

● Text

● Source

● the number of comments

● Categories/Tags

5. TheIndex.Fund

Based on our modules, we have successfully developed a complete system including 5 index funds (TheIndex.Fund) - giving investors the opportunity to invest in most of the crypto market in the easiest way. In a short period of time, a low-cost, modular solution allows Zichain to build the fund's infrastructure, implement quantitative portfolio management, and integrate functions to support fiat currency storage.

被动策略可长期超越积极管理的策略，特别是如果投资者正在努力争取低波动性和稳定收入。 各种被动策略之一是投资于追踪大市场或其个别行业动态的指数产品。 ETF（交易所买卖基金）是投资大盘市场的最便捷方式。 在过去的20年中，它们已经成为机构投资者和个人投资者最热门的工具之一。 ETF目前在全球拥有超过4.5万亿美元的资产。

ETF金融产品的投资量及其绝对值数量的增长

尽管ETF行业在过去13年增长了1，000％，但与共同基金行业相比，这一行业仍然微不足道，而共同基金行业在同一时期仅增长了150％。 ETF管理的资产数量现在只是共同基金资产的十分之一。

认识到加密货币和区块链技术潜力的投资者数量每天都在增加。数字资产区别于传统资产，其特征包括，供给有限、与传统金融工具具有低相关性或呈现出负相关、而且它独立于任何国家所制定出的货币政策。技术的改进，实际解决方案的更广泛分布以及监管机构形成的系统化方法可能会导致投资成本进一步增加。

我们创建了自动加密货币指数基金，为快速增长的数字资产提供简单，透明的访问。 通过只购买一个代币，任何投资者都可以获得与大部分加密货币市场资本完全一致的低成本和多元化投资组合。

指数基金依赖我们的五大指数，因此投资者有机会选择适当的风险回报情况，行业风险（货币，服务或平台）以及多元化程度。

和TheIndex.Fund的投资优势：

加密货币市场的一个入口点—— 一个代币代表投资组合。

多种定制指数基金——从简单的大盘策略到特定的行业风险。

较低的费用——节约成本的操作，订单执行和再平衡。
