With the advent of a new round of industrial revolution, the role of next-generation information technologies such

as cloud computing, big data, Internet of Things, and blockchain in smart manufacturing, finance, energy, and tourism

industries is becoming more and more important. In this round of industrial revolution, the development of blockchain

information technology is particularly rapid, and gradually becomes the direction of deepening the application of

information technology in various industries. From the current development trend and the development path of

blockchain technology, the development of blockchain technology and applications requires cloud computing, big data,

Internet of Things and other new-generation information technologies as infrastructure support, while blockchain

technology and application development Promoting the development of a new generation of information technology

industry has an important role in promoting, which is precisely the historical premise of this technological innovation.

Based on this premise, the well-known technical characteristics of the blockchain: with its trustworthiness,

security and irreversible modification, more data is liberated and the massive growth of data is promoted. The

decentralized nature of the blockchain allows data to be stored in the blockchain from every step of the acquisition,

transaction, circulation, and computational analysis, resulting in an unprecedented endorsement of data quality and

data analysis results. The correctness and effectiveness of data mining. The blockchain can further standardize the use of

data and refine the scope of authorization. For data transaction circulation, it is beneficial to break through the

information island, establish a horizontal circulation mechanism of data, and based on the value chain of the blockchain,

gradually promote the formation of a global data transaction scenario. In response to this scenario, the global asset

digital chain field is also This has entered the tide of the blockchain application era.

The global asset digital chain is a very high threshold for the industry. The targeted groups are paid for by

commercial consumption, including (big health, health care industry, health food, medical consumption, tourism,

tourism payment, hotel consumption, farm consumption). ,) The upstream and downstream giants are involved in the

field, which involves the digitization of some industrial assets in the world, the application of mobile APP, and a series of

chain industries. Therefore, it is extremely strict in terms of safety factor, confidentiality, and contractual spirit. Technical

blockchain data in global application payment digital wallet mode. Convenience.

Chapter 1. Background introduction

1.1 Blockchain as a technological innovation

1.1.1 Blockchain 1.0 Phase - Digital Currency

At the beginning of 2009, the Bitcoin network was officially launched. As a virtual currency system, the total

amount of Bitcoin is defined by the network consensus agreement, and no individual or organization can modify

the supply and transaction records at will. After many years of successful operation of the Bitcoin network, some

financial institutions began to realize that the underlying technology that supports the operation of Bitcoin - the

blockchain is actually an extremely clever distributed shared ledger and peer-to-peer value transmission


technology, for financial and even various lines. The potential impact of various industries may even be no less

than the invention of double-entry bookkeeping.

Chain data block structure in blocks: Each node of the blockchain system selects a block node with package

transaction authority through a certain consensus mechanism. The node needs to hash the current block of the

new block and the current The timestamp, the valid transaction that occurred during a period of time, and the

Merkel root value are packaged into a block and broadcast to the entire network. Since each block is linked with

the previous block by cryptographic proof, when the blockchain reaches a certain length, the block must be

modified to modify the transaction content in a historical block. The transaction records and cryptographic proofs

of all previous blocks were reconstructed, effectively preventing tampering.

1.1.2 Blockchain 2.0 Phase - Smart Contract

Around 2014, the industry began to recognize the value of blockchain technology and use it in areas other

than digital currency, such as distributed identity authentication, distributed domain name systems, and

distributed autonomous organizations. These applications are called distributed applications (DAPP). Building a

DAPP from scratch with a blockchain technology architecture is very difficult, but different DAPPs share many of

the same components. Blockchain 2.0 attempts to create a shareable technology platform and provide BaaS

services to developers, greatly improving transaction speed, greatly reducing resource consumption, and

supporting multiple consensus algorithms such as PoW, PoS and DPoS, making DAPP development It's easier.

With the continuous deepening of blockchain technology and applications, the blockchain 2.0 represented by

smart contracts and DAPP will not only support the architecture system of various typical industry applications.

Behind the various forms of organization, society, and so on, you may be able to see the shadow of this distributed

collaboration model of blockchain. It can be said that the blockchain will definitely change people's lifestyles

extensively and profoundly. Blockchain technology may be applied to the scale coordination of human activities,

and some people even boldly predict that human society may enter the blockchain era, namely blockchain 3.0.

1.1.3 Blockchain 3.0 Phase – Commercial Blockchain Application under Global Consumer Payments

GDD is a comprehensive platform based on Ethereum's decentralized, social, all-open source, reserve gold

and other resources, and a collection of entertainment consumption. The open source software designed and

released is a branch of the ETH network and is a digital currency in the form of P2P. Unlike most currencies, GDD


Token does not rely on a specific currency institution to issue, it is generated by a large number of calculations

according to a specific algorithm. GDD Token uses a distributed database of nodes in the entire P2P network to

identify and record all trading behaviors, and uses cryptographic design to ensure the security of all aspects of

currency circulation. The decentralized nature of P2P and the algorithm itself ensure that the currency cannot be

manipulated manually by making a large number of Tokens. The cryptography-based design allows Tokens to be

transferred or paid only by the real owner, which also ensures the anonymity of currency ownership and circulation

transactions. Based on the ubiquity of smartphones and the growth of bandwidth.

1.2 Blockchain: Technology of industrial data

The technology of global asset dataization has changed the actual scene under the application of blockchain

technology. The technology of global asset dataization refers to the related business under the operation of most

industrial chain institutions including contractual financial institutions in the traditional sense. , refers to a financial

institution that absorbs funds from the contract holders in a contractual manner within a certain period of time

and then performs the payment or fund return obligations to the holders in accordance with the contract.


Including global industry, big health, health care, health food, tourism market, winery, farm, global asset

digitization, mobile APP application, consumption, payment and sale contract. The characteristics of such

institutions are that the sources of funds are reliable and stable, the use of funds is mainly long-term investment,

and contractual financial institutions are important institutional investors in the capital market.

With the development of global digitalization of assets, the industry's pain points and reform direction in the

consumption and payment markets must shift from product factors to human factors, and human factors will

become more apparent. In order to solve this problem, GDD has reached strategic cooperation with a number of

organizations, and has taken the lead in launching the “GDD Smart Global Digital Assets Program” project, based

on data usage and consumption habits data samples based on payment habits, product risks, financial operations,

etc. Blockchain mode.

Nowadays, with the development of blockchain and the wide application of technology, the status of “global

asset payment + technology ” has evolved to “ technology of global asset dataization ” , and blockchain

technology has been applied to all financial payment and industrial chains in the world. It will completely change

the actual demand of the cooperation system in the business before and after the global asset application

purchase, thus solving the trust and security issues in the transaction and becoming the future development trend

of GDD in the future. Through the blockchain, both parties can conduct business activities without the need for

third-party trust brokers, thereby reducing assets for global health, health care, health food, healthcare platforms,

tourism and tourism industries, hotels, The cost of consumption, payment, and purchase of farms and the speed of

capital operation, technology to promote the optimization process of global word assets application.

1.3 Application scenarios of blockchain in global asset digitization

Nowadays, blockchain has become a hot topic in various fields of science and technology, and blockchain

technology has been widely used in various industries. Then, whether the combination of "blockchain + global

asset digital application" is feasible, whether it can meet people's expectations, and further verification. Will the

future blockchain be applied and developed in the field model, is there any development prospects?

"Who owns the user's data? Who should use it?" These issues are no longer a headache, because the

blockchain can solve these problems and can use the blockchain to create a mechanism for asset digital data

applications. For the consumer, on the one hand, through the GDD+ blockchain combined products and services,

enjoy the intelligent consumer payment application brought by the digitalization of global assets in the intelligent


era, and obtain the blockchain reward income based on consumer behavior. In terms of global asset digitization,

blockchain technology complements the existing financial service system, and then forms more financial products

to meet the actual needs of global asset consumption and payment groups.

Chapter 2. Explanation of GDD

2.1 What is GDD?

The GDD team is committed to building the world's most competitive global asset digital application chain –

GDD Token for global commercial consumer payments and asset consumption payments. The team used and

optimized its functions based on third-generation encryption technology in October 2017. It plans to release

Token to the market in the second half of 2018, with a total of 580 million, while maintaining a policy of

never-issuing to maintain the price of digital currency. stability.

GDD is a comprehensive platform based on Ethereum's decentralized, social, all-open source, reserve gold

and other resources, and a collection of entertainment consumption. The open source software designed and

released is a branch of the EHT network and is a digital currency in the form of P2P. Unlike most currencies, GDD

does not rely on a specific currency institution to issue, it is generated by a large number of calculations according

to a specific algorithm. GDD uses a distributed database of nodes in the entire P2P network to identify and record

all trading behaviors, and uses cryptographic design to ensure the security of all aspects of currency circulation.

The decentralized nature of P2P and the algorithm itself ensure that the currency cannot be manipulated manually

by making a large number of Tokens. The cryptography-based design allows Tokens to be transferred or paid only

by the real owner, which also ensures the anonymity of currency ownership and circulation transactions. The

ubiquity of smartphones and the growth of bandwidth have changed the lives of modern people. GDD adopts the

mobile application APP landing application strategy of [mobile first].

2.2 GDD algorithm description

Release name：GDD

Quantity: 580 million pieces

Machine operation distinction: mobile phone client and computer client


Machine operation plan: Open the Apple APP and Android APP client on July 1st, 2018. Before July 1, 2019,

open the computer client with the time of the exchange.

Goal: Build the world's most competitive global asset digital application chain – GDD Token can be used for

global commercial consumption payments and asset consumption payments. In the GDD platform, each user can

freely register an independent distributed account, and automatically generate the money-bearing income

according to the user's actual currency management and currency holding time.

he algorithm of GDD wallet mainly adopts POS mode (equity certificate), similar to property savings in the

bank, according to the number and time of GDD held by the user, the corresponding currency is allocated. In POS

mode, each GDD digital asset wallet can be Enjoy the computing power brought by the holding of the coin until it

is finished. The core algorithm of GDD Digital Asset Wallet is ETH.

2.3 GDD ecological scene

Based on blockchain technology, GDD can achieve global asset dataization, including industries (big health

industry, health care, medical platform, tourism and tourism industry, hotels, farms), such as building blocks,

adopting global business data. Step by step to digitize the blockchain, thus forming a commercial asset kingdom.

For example, the producer uploads data marketing in GDD, and the consumer is in the GDD digital wallet purchase

and consumption, which is based on the technology of the blockchain foundation, and the third party

management (the third party is also the blockchain system), through the system application operation, Do your

own credit, free trade, asset trust, etc.

2.3.1 Perfection of GDD ecological foundation

The application chain of GDD can solve the fundamental problem of price chaos, information circulation,

fairness, and true and false in the commercial industry. In the commercial market, consumers can use GDD to

identify the global health, health care, health care platform, tourism and tourism industry, the ecology and source

of hotels, farms, and information opacity, which cause the market price to harm the interests of consumers.

2.3.2 Open and transparent, data traceable

GDD is based on the RFID underlying chain technology, which can track and identify the production location,

production time, transportation until the end of the sale process, consumers can view every consumption


information on the mobile phone.

2.3.3 Social Ecosystem

GDD will establish a community in each region in the world to jointly create commercial digital asset

technology applications and global industrial consumption, and pay for a social win-win ecosystem. In the process,

each member has the opportunity to receive rewards through the GDD mechanism, which maximizes the

enthusiasm and creativity of all community members and thus enhances the GDD community's influence.

2.3.4 Construction of traceability platform for big data

GDD will cooperate with the global health, health care, medical platform, tourism and tourism industry, hotel,

farm industry ecology and commercial marketers to launch the establishment of environmental protection and

energy-saving commercial RFID traceability technology research center, through the environmental protection

and energy-saving industrial chain data Link tracking acquisition, create GDD big data platform.

2.3.5 Credit System Construction

Through the decentralization of the blockchain, the data exchange between nodes through digital signature

technology, without mutual trust, and under the premise of smart contracts, the contract parties can not deceive,

only when the contract conditions are met, the program will release Or transfer funds. Under such a system, the

cost of buying and paying for global digital assets will be greatly reduced.

Chapter III. GDD payment application landingMobile GDD payment application platform landing, blockchain technology has removed the dependence on

the central authority. Since blockchain technology handles transactions in a peer-to-peer fashion, the distributed

structure eliminates the need for third-party agencies to record and settle transactions. Therefore, the payment

system based on the blockchain has the characteristics of“de-intermediation”. This may change existing payment


systems characterized by centralized clearing.

3.1 creation of direct value

Mobile GDD payment platform is currently the fastest growing technology application in the fields of big

health industry, health care, medical platform, tourism and tourism industry, hotel and farm payment. Blockchain

technology can avoid complicated system in payment. A more direct payment process between the person and

the payee, whether it is a domestic transfer or a cross-border transfer, is characterized by low prices and speed,

and there is no intermediate fee. The primary application of blockchain technology is embodied in distributed

ledgers for cross-border payments. Today's cross-border payment networks are fragmented and isolated,

resulting in a lack of cost competitiveness, long settlement times, and poor user experience. Cross-border

payments must be handled by various proxy banking relationships using different messaging protocols and

settlement agreements. Statistics show that these inefficiencies cost the entire community a total of $1.6 trillion

annually.

Mobile GDD is the world's first global asset digital payment company that uses a common global

infrastructure to connect these isolated networks, real-time settlement with distributed ledgers, ensure

transaction certainty, and reduce risk. Financial settlement efficiency.

3.2 Remove the traditional intermediate point

The mobile GDD payment platform can eliminate the intermediate links of third-party financial institutions,

allowing the cross-border network payment settlement transactions of both parties to be completed quickly and

freely in a point-to-point manner. At the same time, it can be paid around the clock, real-time arrival, cash

withdrawal is simple and there is no Implicit costs. Not only that, because the blockchain is safe, transparent, and

low-risk, it can also improve the security of cross-border remittances, speed up settlement and clearing, and

greatly improve capital utilization. According to McKinsey's estimates, globally, the application of blockchain

technology in B2B cross-border payment and settlement services will reduce the cost per transaction from

approximately $26 to $15.


3.3 The huge application of mobile phone GDD

In current offline trading scenarios, cryptocurrency is not widely used. With the increasing use of

cryptocurrencies and ideas, it is believed that in the near future, cryptocurrencies will also be integrated into our

daily lives and consumption. Each year, the amount of consumption generated between consumers and

businesses is expected to reach $22 trillion. People pay for all their consumption in local currency, from a cup of

coffee every morning to weekly shopping. The mobile phone GDD platform is promoting large-scale health

industry, health care, medical platform, tourism and tourism industry, hotels and farms to fully accept

cryptocurrency. By leveraging the existing global business ecosystem, the mobile GDD platform will greatly

accelerate the popularity of cryptocurrency.

The global payment for mobile GDD will be to create a business that is universal and can replace traditional

banks. By using GDD tokens, you can securely store your funds and trade them in any currency, including

cryptocurrencies. All operations can be done through the OSO Network Node application installed on a global

merchant. The digital wallet created by GDD can replace the traditional commercial payment model, allowing you

to complete payment transactions in any type of currency anywhere in the world.

3.4 value of GDD

On the GDD platform, the value is reflected in the following aspects:

First, high efficiency; after the traditional center forwarding architecture, the payment time is reduced from

minutes to seconds;

The second is high availability; failure of any node in the distributed architecture does not affect the operation

of the entire system;

The third is high security; in a network environment with a private chain closed, it is difficult to forge a

message;

The fourth is high scalability; new participants can be quickly and easily deployed and added to the system.

3. 5. GDD advantages

Advantage 1: Free economy

Free economy: the traffic age is free for the king, whether it is WeChat Weibo or Facebook is the first user


to do the project, including the early computer all-bit mining of Bitcoin is free, zero investment means

everyone can participate in the project

Advantage 2: blockchain technology

As a representative of the new digital currency, GDD also has open source code and wallet, but the platform

uses the internal mining of the cloud mining machine within one year in order to allow everyone to compete fairly

and fairly on the same starting line, and to lay a user base for the future opening of the mining pool. To achieve the

role of protecting the value of money.

Advantage 3: Decentralization

Decentralization: The platform does not charge money and only accepts transaction fees. The transaction is a

direct point-to-point payment by the player, so there is no need to worry about the platform to run the money. On

the contrary, the longer the platform is, the longer the fee will be collected, so the platform will only be more

Steady development.

Chapter 4. Technical Architecture of GDD

4.1 Platform Design

4.1.1 Consensus mechanism——POC

The modular design of GDD supports the replacement and insertion of all core functional modules including

the consensus mechanism. The main chain defaults to the credit consensus mechanism POC (Proof-Of-Credit).

Anyone can participate in the blockchain network, each device can act as a node, and each node is allowed to

obtain a complete database copy. The nodes maintain a common blockchain through competitive computing

based on a set of consensus mechanisms. If any node fails, the remaining nodes will still work normally.

The consensus mechanism is a core issue of blockchain technology. It determines the rules for generating

blocks in the blockchain, ensuring the honesty of each node, the fault tolerance of the books, and the robustness


of the system. Different application scenarios based on blockchain technology and the characteristics of various

consensus mechanisms can be evaluated and compared in terms of performance efficiency, resource consumption,

fault tolerance, and regulatory level. The Consensus Mechanism feature has the following features:

(a) Support multiple nodes to participate in consensus and confirmation;

(b) Support independent nodes to verify the validity of relevant information submitted by the

blockchain network;

(c) Prevent any independent consensus nodes from recording or modifying information in the

blockchain system without confirmation by other consensus nodes;

(d) There should be some fault tolerance, including non-malicious errors in node physical or network

failures, as well as malicious errors in which nodes are subject to illegal control, and

uncontrollable errors in which nodes generate undefined behavior.

4.1.2 Equity certificate——POS

POS is also called equity certificate, similar to the property stored in the bank, this model will be assigned to

the corresponding currency according to the amount and time of the digital currency you hold. To put it simply, in

the equity proof POS mode, there is a noun called the currency age, and each coin produces 1 currency per day.

For example, if you hold 100 coins for a total of 30 days, then your coin age is 3000. At the time, if you find a POS

block, your currency age will be cleared to 0. Every time you are emptied by 365, you will get 0.05 coins from the

block. In this case, interest = 3000*5%/365=0.41 coins, so that the currency has interest, there is a big advantage in

POS mode is to save resources, only need lower computing power to maintain the operation of the entire

blockchain network, and some even Through the short-term mining stage in the previous period, it directly enters

the pure POS mode, so that it is possible to confirm the whole network transaction only by running the wallet

client without mining.

POS is a completely different mechanism than POW. POS does not require a lot of computing power to

maintain network security. It only needs each participant to open their own wallet to increase network weight and

obtain corresponding rewards, which is the POS mechanism itself. Said interest.


4.1.3 Smart Contract

GDD creates a smart contract that combines a non-turing-complete backbone with a Turing-complete

sidechain. A smart contract is an assembly language programmed on a blockchain. Usually people don't write

bytecode themselves, but they compile it from more advanced languages, such as a proprietary language like

Solidity, Javascript. These bytecodes do provide guidance for the functionality of the blockchain, so the code can

easily interact with it, such as transferring cryptographic currency and logging events. The execution of the code is

automatic: either successful execution or all state changes are undone. This is important because it avoids the

execution of the contract portion (for example, in a securities purchase transaction, the security owner has

transferred the security, but the cryptographic currency payment transfer failed). This is especially important in a

blockchain environment because there is no way to undo the bad consequences of execution errors (and if the

opponent does not cooperate, there is simply no way to reverse the transaction).

Blockchain-based smart contracts not only take advantage of the low cost and efficiency of smart contracts,

but also avoid the interference of malicious behavior on the normal execution of contracts. The smart contract is

written into the blockchain in a coded form, and the data storage, reading and execution process using the

blockchain technology can be traced and transparent and cannot be tampered with. In addition, a state machine

system constructed using the blockchain consensus algorithm enables intelligent contracts to operate efficiently.


The functional components of a smart contract include:

A development operating environment, including:

(1) Provide programming language support and provide a supporting integrated development environment

when necessary;

(2) Support contract content static and dynamic checking;

(3) Provide support for running carriers, such as virtual machines;

(4) For smart contracts that interact with external data of the blockchain system, the scope of influence of

external data sources should be limited to the scope of smart contracts and should not affect the overall

operation of the blockchain system.

B storage environment, including:

(1) Prevent tampering with the contents of the contract;

(2) Support the upgrade of contract content under multi-party consensus;

(3) Support the writing of contract content to the ledger.

4.1.4 Quantum Entanglement Encryption Technology

GDD adopts quantum entanglement technology and is a secure encryption technology for transmitting

information. Related to information transmitted by superluminal speed. The speed of "communication" between

these particles is fast, using this connection to control and deliver information at such a fast rate.

At the same time, asymmetrically encrypted public-private key pairs are also used in the blockchain to build

trust between nodes. The asymmetric encryption algorithm consists of a corresponding pair of unique keys (ie,

public key and private key). Anyone who knows the user's public key can encrypt the information with the user's

public key and interact with the user to implement security information. Because of the dependency between the

public key and the private key, only the user holding the private key can decrypt the information, and any

unauthorized user or even the sender of the information cannot decrypt the information. The encryption feature

has the following features:


Support international mainstream encryption algorithms, such as asymmetric encryption

algorithms such as AES256 and asymmetric encryption algorithms such as RSA and ECC;

Supports confidential algorithms, such as SM4 and SM7 symmetric encryption algorithms and

asymmetric encryption algorithms such as SM2 and SM9.

A clear key management scheme should be in place to ensure that the underlying security

mechanism of the blockchain operates normally;

The encryption algorithm should have the ability to resist cracking. It is advisable to periodically

review the security of the encryption algorithm and, if necessary, use a higher encryption

algorithm that computes the complexity.

。

4.1.5 Multi-chain (main chain-sub-chain--sub-chain)

Independent blockchains complete the value production of highly relevant business areas. To achieve social

goods and value circulation, cross-chain trading markets are needed, and cross-chain value exchange markets

provided by cross-chains can satisfy the value of different subjects. Price circulation. Cross-chain compatibility, can

be compatible with existing and future blockchains; cross-chain is open, cross-chain has the ability to link any

block; cross-chain has standardization potential, allowing any block to link, An access standard will gradually

emerge to help promote the standardization of blockchain protocols.

According to the needs of business functions, privacy protection, data isolation, or performance capacity

expansion, GDD establishes multiple independent chain parallel jobs. Chains and chains can interact with each

other through cross-chain services, such as sending transactions, querying transaction results, and reading.

Configuration data, etc. The intelligent contract data interaction between different blockchains enables

interoperability between blockchains. In complex business scenarios, independent sub-chains (logical/physical) of

fine-grained operation can be designed and passed through the parent- Sub-smart contracts meet different

business needs and increase the flexibility of the overall “bloated” books.

Through cross-chain technology, GDD integrates the business-style private chain/federal chain into the

consensus network of the main chain, while retaining the privacy and licensing protection of the private

chain/federal chain. According to the needs of business functions, privacy protection, data isolation, or

performance capacity expansion, multiple independent chain parallel work is established, and the chain and chain

can interact through the cross-chain service. Other digital assets connected to GDD, first need to complete

registration on GDD, can be independently developed or customized development, access GDD, and achieve


interconnection.

In the GDD blockchain network: the "main chain" constitutes the information trunk road, and the different

parent chains exchange information by protocol through the link. At the same time, a main chain carries different

isomorphic sub-chains, which are distributed account books of a vertical domain or multiple cross-industry

clusters. Communication between sub-chains is achieved by a cross-chain communication protocol. Through the

fragmentation of the blockchain, the transaction processing capability of the blockchain system is improved.

Compared to a single blockchain system, a chain cluster system can grow linearly in transaction processing

capacity by connecting multiple sub-chains. The request for the transaction enters different sub-chains through

the assignment of the link, which can effectively circumvent the centralized request for one sub-chain. In addition,

we can deploy clusters with different number of nodes in the isomorphic sub-chain on the link. For the isomorphic

chain, the number of nodes with multiple nodes will have relatively high security, and the processing speed of the

cluster with fewer nodes will be more. fast. In addition, different chain clusters are deployed according to different

requirements such as the number of nodes, geographic location, and service classification. The requests are

distributed to the appropriate clusters for different requirements. The help chain network is flexibly deployed


according to service requirements to provide users with higher quality. Blockchain service.

4.1.6 Asymmetric Encryption

Elliptic Curve Cryptography (ECC) is a public-key encryption technique based on elliptic curve theory that can

be faster, smaller, and more efficient when creating keys. ECC uses the properties of elliptic curve equations to

generate keys instead of using traditional methods to produce products with large prime numbers. Elliptic Curve

Cryptography (ECC) is a public key cryptography technology. Based on the elliptic curve theory, the Abel group

discrete logarithm of the elliptic curve on the finite field is used to solve the problem of encryption, decryption

and digital signature. Corresponding to the elliptic curve, the corresponding cryptosystem can be established by

adding the addition operation in the elliptic curve to the modular multiplication operation in the discrete

logarithm. The elliptic curve is a plane curve determined by the following Weilstras Weierstrass equation:

E:y2+a1xy+a3y=x3+a2x2+a4x+a6

The elliptic curve encryption algorithm has a small key length, high security performance, and low time

consumption of the entire digital signature, which makes it have great potential for development in smart terminal

applications, such as handheld computers and mobile phones. . In the network, the ECC algorithm also guarantees

the real-time performance of its collaborative work. The ECC algorithm is used to encrypt data with high sensitivity

level (such as key), which can meet the requirements of large data volume in speed, and has high security and can

be very Good security of the system.

4.2 GDD blockchain architecture

Earlier we mentioned that blockchain technology is more like a technical architecture that uses a combination

of different technologies. In the generalized blockchain technology architecture, it can be roughly divided into

three levels:

Protocol layer: In this level, it represents the core of the blockchain. It is also the underlying technology that is

currently known in the market. It contains the structure of the data storage, consensus algorithms, encryption

mechanisms, network communication protocols and so on. All of this content is wrapped around this layer to

operate and provide upper-level calls in the form of APIs or services.


Expansion layer: The expansion layer is like the V layer in the traditional MVC architecture, which handles part

of the business logic. Smart contracts are built on this layer. So at this level, we can extend blockchain technology

to a variety of scenarios through smart contracts, such as AI artificial intelligence, VR/AR, IoT <IOT>, ERP/MES, Big

Data <Bigdata>, cloud Platform <Cloud> can be implemented here.

Application layer: The application layer is for the end user. For those who have contacted the virtual currency,

different "electronic wallets" belong to this layer. However, in practical applications, due to the limitations of the

blockchain technology itself. In addition to the needs of users, the development of the application layer must also

take into account the logical and technical requirements of the extension layer and the protocol layer. This leads to

a blockchain development project that will require more complex teamwork.

From the above architecture, it can be found that the blockchain technology may be a different programming

language and separate arithmetic logic in each architecture layer. At the same time, it must cooperate with the

encryption algorithm requirements of the business itself, etc., which will form a complex collaborative process.

Behind it is the need for complete business logic to meet the real needs of the market.

4.3 Technical characteristics

The overall characteristics of GDD technology are open, transparent, verifiable, or at least within a certain

range. In terms of effect, it is not tamperable and traceable. The project should choose a more open

public-chain-like architecture because the project has high requirements for privacy, and there is a strong demand

for process transparency.

Of course, the project Ethereum 20 blockchain technology, but from the current technical capabilities and the

needs of cross-border payment, it is not excluded that the project will build a new chain and consensus

mechanism, just like the GDD consensus mechanism.

The advantage of this is that it does not rely on the workload proof of a large amount of power consumption,

like the current Bitcoin blockchain, and can set the data disclosure degree and influence surface within the

controllable range. Through big data, the behavior of the Alipay user node can be used as a basis for effective

judgment, and it is not difficult to unify the solution due to uncontrollable node behavior after the error like The

DAO. Of course, the proprietary blockchain is more suitable for tailoring the project according to its own

development needs.


Chapter 5. Introduction to Virtual Currency Issuance Rules

5.1 Virtual Currency Description

GDD is a settlement virtual currency based on the mobile phone GDD system platform, which is used to

exchange and settle other currencies on the GDD system platform. GDD provides a trading medium for user

transactions on the GDD system platform.

GDD is the only virtual currency in the parent chain of the entire ecosystem. Any data exchange and asset

exchange across the sub-chains need to consume the parent-chain virtual currency. When the ecosystem is

formed, the cross-chain data interaction becomes a high-frequency event. The demand for Token continues to

increase. The virtual currency holder has the original distribution rights of the parent chain development direction.

Like Ethereum, after GDD is launched, in addition to continuously strengthening its technological leadership,

it will continue to release new technologies and applications in the chain, fully expand its ecological structure and

enrich its vitality, and realize the property switching from private chain to platform to public chain. .

The emergence of GDD will redefine the new industry standard for cross-border financial payment services: to

become the standard for financial payment contract blockchain, and to become the basis for future new

technology development and new application release.

In the case of GDD's technological leadership, open source code will become the underlying technology for

many future projects, including government, corporate, and individual projects in practical application scenarios

across countries.
