Unlimited Inflation
Unlimited Inflation
2020 is a year worthy of being remembered in history, as all the sins of Keynesianism seem to break out in this year.
Keynesianism is government interventionism. The market economy has its own defects, and only when the government intervenes can we achieve the macro-economic goals such as eco-nomic growth and unemployment decline. The main strategy of such intervention is usually un-limited currency issuance, and the ultimate result is unlimited inflation of the legal currency. People's wealth has been quietly diluted in suc-cessive rounds of quantitative easing.
In the last century, Germany's currency devalued 100 billion times in nine years. German people even burned money to keep warm, because that pile of money wouldn't be exchanged for several pieces of wood, and it's better to burn money di-rectly. The thief would rather steal the bag of money than the money, because the newly stolen money may immediately depreciate to the point where he can't afford to buy a bag.
Venezuela, because of the lack of time for cur-rency printing domestically, commissioned the underground money printing factory for addi-tional printing. As a result, the total value of the additional printed money is not enough for freighting.
Before liberation, the national government print-ed and issued 'gold coupons', which eventually led to the collapse of the national economy.
The U.S. government, the world's largest robber, has used a smarter and more secretive approach to issue 'credit currency', which must correspond to the value assets of the society. Take credit (future repayment) as the corresponding value of the printed currency. However, it's just not rob-bery on the surface.
In March 2020, the U.S. stock market meltdown five times in an unprecedented way, and the U.S. government's prescription for this is infinite QE (Quantitative Easing), which is astonishing. The world's most powerful country has declared di-rectly to the world that it will use inflation to drag the world down. How fragile the wealth is on paper at this moment!
The right of coinage is so addictive that no regime will voluntarily give up it, and the colli-sion between it has created exchange controls. In an ideal society, value should circulate freely and should not be framed by boundary. The value of things should somehow be fixed. A grain of rice is a grain of rice. But under the control of foreign exchange in different countries, we find that it has different prices. To some extent, al-though the state and currency give value a price, they are also the distortion field of value.
Wondering thathave you ever thought about why you can't directly buy high-quality stocks of de-veloped countries or invest in rising real estate in emerging countries by your hard-earned money.
1BEGINNING1
Asset Freedom
The world is like a cell wall glued together and the energy needed to break through the cell wall is so great that ordinary people, whose body or property, are imprisoned in a small 'cell'.
But this border is being broken gradually. It is not new for some people to use BTC for cross-border exchange. We are even more surprised to find that Bank Frick, a European bank, has started to use USDC as stable currency instead of SWIFT for cross-border transfer. Large institutions also began to enjoy the bonuses of blockchain break-ing the border.
The history of human development is a history of integration, from individuals, to families, to tribes, to countries, to global villages. Physical distance, through cars, ships, high-speed rail, aircraft and other high-speed means of transpor-tation, is no longer a problem. The reduction of the time span of distance makes the earth con-dense into a real global village. The span of in-formation, through the development of computer technology and the Internet, has led to the inter-action within a second. Today, we can watch Marvel's films in any country, feel the country-side flavor of Great Britain and enjoy the beauti-ful scenery of Switzerland. In terms of finance, the borders set up by governments of all coun-tries are gradually disappearing under the im-mersion of blockchain technology.
The future world is a world without boundary.
In the novel named Nineteen Eighty-Four: big brother's photos are posted everywhere in the streets and alleys. A large TV screen monitors people's every move. The monitored people can't show any expression with personal emotion. All people live a stylized life every day like a body without soul.
In some countries, transfers over 100000 will be monitored. Transfers between accounts in legal currency can be frozen as a result of investiga-tions by the judiciary. With the development of the covid-19 epidemic, Sweden and the UK began to expropriate funds from some unused fi-nancial accounts for a long time as the cost for the epidemic.
Have we ever thought that when this happens, it also indicates that the wealth that makes us feel at ease is not really under our control. Money is just a number, and it's not controlled by individu-als.
In terms of the management of the state and the government, there is nothing wrong with this. But such a management system makes people think that people at the bottom are like the herd-ing sheep for the powerful.
This is contrary to the a human nature, freedom. People come to the world naked, but they become puppets of the world. However, people are used to it and don't question it.
Should human beings wonder why they are born to be enslaved? Is it to be happy for unreal num-bers? Why is the world so absurd? Why do people never have the right to control their wealth?
Money is actually not money.
Money is debt; money is credit; money is voucher, but money is not money.
Depression years has led to people’s depression, discontent and doubt, which are widespread and profound.
The world is sick, and it needs to be rescued ur-gently. The financial history of the world is a his-tory of exploitation of the world. The powerful class defines money and the rules of money. Under the condition of unlimited operation of the rules of the game, people can only fall into ex-ploitation with the replacement of the powerful generation by generation, like reincarnation.
Only mathematics will not deceive you and only mathematics will not betray you. Through block-chain technology and cryptography, human beings can have what they have for the first time in a real sense, instead of relying on others' rules.
The financial crisis in 2008 gave birth to BTC. Among the founders, Satoshi Nakamoto is an anarchist, whose original intention is not to let the digital cryptocurrency be controlled by a government or central bank, but to make it become a global free flowing currency that is not regulated and controlled by the government.
BTC has become an unstable factor outside the legal currency system of various countries. How-ever, due to technical limitations and lack of smart contracts, BTC cannot become the system itself. Standing on the shoulders of giants and following Hayek's idea of free currency, DFD SYSTEM proposes a revolutionary financial ecol-ogy of borderless decentralization.
In the long run, we are all dead.
When all rivers return to the sea, the general trend and the wheel of history roll forward, and Keynesianism will never return. The world line is tightening because of the unrestricted easing of government. In 2020, the U.S. stock market ex-perienced five meltdowns in March, indicating that the world line has begun to restart
As the ancient East said, the year of Gengzi was plagued by many disasters, as if it also con-firmed all this. Middle East refugee wave, covid-19 epidemic, and the 'black lives matter' movement in the United States, etc.... The world began to stir, as if calling for innovation.
Disaster also means change.
The vision of DFD SYSTEM is to create a unique financial Eden for the general public in this ab-normal financial ecosystem full of control and exploitation. In the DFD SYSTEM financial ecolo-gy, money is free to compete, everyone can issue coins, the circulation of money has no boundary, people's assets are no longer controlled by the 'tangible hand', and people can enjoy the real right to dominate themselves. I don't know how amazing the alpine air is without breathing it. The vision of DFD SYSTEM is to bring all the beautiful imagination of future life that people can't imagine to everyone. When DFD SYSTEM ecology is established, people can use all kinds of Internet applications without divulging their privacy. The value of individuals is no longer de-spised by giants and can be respected as much as possible. Everyone can control his property and enjoy the lending and transaction services provided by DFD SYSTEM without borders. The platform of DFD SYSTEM issues personal tokens, finances, and sells its own goods to every place in the world through the Babel vein.
DFD SYSTEM is born for freedom, fairness, rights, fighting and unyielding.

Brief Introduction of DFD System
The full name of DFD SYSTEM is Decentralized Financial Data System, which is blockchain 4.0.
BTC is the representative of the first generation of blockchain, which implements a peer to peer electronic cash system. However, due to the technical limitations, it cannot be used commer-cially at all because of its performance and not supporting smart contracts.
The second generation blockchain is represented by ETH. Compared with blockchain 1.0, the big-gest feature of blockchain 2.0 is that it introduc-es smart contract and programmable base design, which enables people to develop block-chain references for various purposes based on its framework. In addition, due to the improve-ment of consensus mechanism, some commer-cial bases are obtained by using consensus al-gorithms such as PoS.
The representative of the third generation block-chain is EOS and TRON, which have better per-formance and can be used more widely. Howev-er, the current blockchain 3.0 technology mostly uses consensus algorithms such as DPoS, which sacrifices decentralization to obtain perfor-mance improvement through more centralized node scheme, violating the original intention of Satoshi Nakamoto completely.
As the fourth generation of blockchain, DFD SYSTEM completely improves the defects of blockchain 3.0. By adopting the proprietary design of B-DPoS consensus algorithm, it has become a new generation of public chain with the characteristics of decentralization and high-efficiency technology. Only with the char-acteristics of decentralization and high efficien-cy can we develop borderless decentralization fi-nancial ecology.
DFD SYSTEM can achieve the speed of consen-sus no less than DPoS, thanks to the Sunlight node and Starlight node design in B-DPoS con-sensus mechanism. Transaction confirmation can be realized within 3s, and 4000 TPS can be realized in the test network composed of more than 500 nodes, which can initially meet the landing requirements of most commercial appli-cations. Based on this, DFD SYSTEM will realize unlimited expansion of technical performance through cross chain and side chain technology in the future, reaching tens of millions of TPS, which can be perfectly applied to the commercial system application of every industry. High per-formance is a necessary requirement for the future public chain, which is also the reason why the legendary public chain like BTC will be limit-ed in this era. Mobile payment entered the boom phase in 2013, before which 4G network was built. People will not accept the backward con-sumer experience. In the era of decentralized fi-nance, to defeat the centralized financial system, DFD SYSTEM must meet higher requirements, among which high performance is the standard. Through the high-performance design of DFD SYSTEM, users can enjoy the payment experi-ence that is not inferior to the centralized pay-ment experience. Only based on this, the building of various applications is necessary.
DFD SYSTEM has the fol-lowing features:
High Performance
Blockchain technology provides machine trust, absolute justice without private interests at the bottom of technology. With the blockchain tech-nology, DFD SYSTEM has created Babel Tower, which unites people closely. Trust is no longer a scarce thing in Babel Tower. With the blockchain technology, trust flows in Babel Tower like blood. In the past, the tedious rules of the industry have been reshaped. There is no doubt that all kinds of scams in the capital game are exposed in the Babel tower. People can join in the assistance with the lowest cost and the highest efficiency.
Due to the high-performance design of DFD SYSTEM, it will no longer have Gas War on BTC and ETH, nor CPU War on EOS and TRON.
Due to the problem of PoW consensus algorithm, BTC network needs a large range of nodes to reach consensus, resulting in slow network speed, and the priority of miner's packing block is the handling fee of miner, which will cause vi-cious competition when the network is blocked. Such a problem has not been solved in ETH or EOS. High-performance public chains such as EOS have also been blocked by free airdrop. DFD SYSTEM as blockchain 4.0, high TPS ensures that Gas War will no longer occur. Users can use DFD SYSTEM at low cost. Instead of low-level Gas War to ensure the value of the public chain, DFD system will improve its value while bringing convenience to users through various financial applications on the public chain.
he technical scheme of DFD SYSTEM includes starlight nodes. Different from the low participa-tion of ordinary users in the traditional public chain scheme, DFD SYSTEM really gives ordinary users the right to participate in the governance of consensus mechanism. In the mechanism setting of DFD SYSTEM, ordinary users will have great stickiness with it. This stickiness is incom-parable to any existing blockchain system.

Equality Gover-nance
INTRODUCTIONOF DFD SYSTEM FUNCTIONS
Babel TowerIn the Old Testament, human beings united to build a tower that hoped to lead to heaven. In order to prevent human's plan, God make human beings speak different languages, so that human beings could not communicate with each other, thus the plan failed, and human beings have scattered since then.
The power of the individual is insignificant in the changing torrent. Only by integrating the power of the individuals, can we break through the shackles and reach the other side of the ark. The government is not God and they fear the power of people forming groups. When the Babel tower in DFD SYSTEM is built, it will never be destroyed again. In DFD system network, anonymous chat network and private currency authority give ev-eryone full freedom and equal rights that they never had.
In the stone age, people were drinking blood. In the power of individuals, human beings were not powerful. Humans can't beat grizzlies or run tigers, but they were still standing at the top of the biological chain. With unity and cooperation, people hunted all kinds of large animals with weak bodies in the stone age. In modern times, human beings make it possible to complete the story of landing on the moon and other myths. However, the complexity of human nature is also destroying the cornerstone of cooperation - trust. In order to solve the problem of trust, we have paid a lot of trust cost and created a series of complicated things such as law and contract to ensure the cooperation.

Fkey
Babel Vein
DNA Double Helix Growth
Framework
Trust is the core code of Babel tower. The tradi-tional multi-level relationship is opaque and can be tampered with by the project party. In Babel Tower, when the guiding relationship is estab-lished, the links between people will be carved into the Babel vein through the blockchain, which is guarded by the blockchain technology. When the interpersonal relationship is carved into the Babel vein, it can no longer be tampered with. Through the consensus connection of Babel Tower, we have formed a complete community, relying on all life forces to resist inner fear, dare to trust and embrace cooperation. Babel Tower vein is a whole, with no need to trust, the system has built-in trust context, through which com-munication and trading are as smooth as blood circulation.
Babel vein is infinite. Once you have Fkey, the DNA double helix growth structure will be in-finitely derived. This kind of infinite hierarchy will be engraved in Babel Tower. For businesses using it, they do not need to worry about the huge financial pressure as Babel vein itself pro-vides an infinite possibility which businesses can define the use of it according to their own needs.
Only through strong social networks can we build a stable Babel Tower. Babel Tower began to construct the Babel vein with the guidance system. When the DFD SYSTEM main network starts, the Babel Tower will generate the initial Fkey. Only from the initial Fkey can new users be guided into the Babel Tower. Since then, any user who wants to join Babel Tower needs to be guided by the existing Fkey user.
When a new user registers as a resident of Babel Tower, his/her Fkey will be generated after regis-tration, forming his/her 2 invitation codes, sun-light code and starlight code. Users who enter Babel Tower through two guide codes will form a spiral orbit. Only when the spiral orbit starlight system and sunlight system are pushed forward circularly, can DNA be strengthened. The user's DNA enhancement can be displayed clearly through the starlight power and sunlight power.
When users join the DFD SYSTEM community network, they need to generate Fkey (Future Key, the key to ark) through the boot code.
Fkey is the virtual identity of the Internet in the future. Where the ark goes is the other side. Through Fkey, users can access various func-tions and applications provided by DFD SYSTEM. When the Babel Tower is established, the pros-perous ecosystem of DFD SYSTEM will give Fkey more value in reverse. More Internet applications will connect with the residents of Babel Tower through Fkey. Fkey is the anonymous ID of the residents of Babel Tower in the world, but how amazing is that they can enjoy more free Internet services.
Fkey is the pass of DFD SYSTEM community, which is a specially designed blockchain trans-action address. The Babel vein between address-es will be closely related when it is created, forming a continuous fission promotion network. The network forms the vein of Babel tower, and people no longer need to go through guarantors. The smart contract solves the trust problem and ensures the transparent and safe distribution of interests in Babel tower.

When the residents of Babel Tower directly guide new users into it, this kind of direct intensification of Babel vein will give the guide glorious computing power.
Glorious computing power =computing power of direct user on the day * co-efficient of direct computing power
The first floor of the user's two tracks can accommodate one person each, but it can invite countless people. If more than one person is invited, it will automatically slide down and left along the track.
As shown in the figure below: user a uses starlight code to guide B1, and uses sun-light code to guide B2, which is placed on the first layer of two tracks. When using starlight code to guide the next user, the first layer of starlight code is full, which needs to be placed in C1 of starlight code on the next layer (B1). If the position has been used, it needs to be placed in D1 of the next layer. It is the same with the guid-ance of sunlight code, placing according to C3, D5 and other positions in the figure.
According to the position in the figure, D1 can be guided by A, B1 or C1, and D5 can be guided by A, B2 or C3.
It should be noted that the right side (sun-light code) position of lower level users cannot be placed over the layer. In other words, D2 can only be guided by C1, D6 can only be guided by C3.
Users use the two guide codes of starlight and sunlight to promote respectively, to the two spiral orbits of starlight track and sun-light track.
At 24:00 every night, the sum of the com-puting powers of the infinite users on the two tracks is calculated and compared. The computing power of the track with smaller computing power * the computing power coefficient of the spiral track is calculated, and the computing power of the spiral track of the user is obtained, which is up to 30 times of the computing power of its own miner.
For example: player a spent 100USDT equivalent DFD to purchase level 2 miner in the figure below. The miner's computing power is 1, and the computing power coef-ficient of spiral track is 6%. Two users are guided, which are respectively placed on the a starlight track and the sunlight track. The two users guide two users respective-ly, and the total computing power of the two tracks is 250 and 200 respectively. Take the sunlight track value, 200 * 6% = 12. Since it fails to reach 30 times of the calculated force of the miner, so the spiral force obtained by A is finally 12.

DFD SYSTEM is different from other pseudo de-centralized public chains, where super nodes have the highest authority, while ordinary people can not participate in the establishment of the network, and capital monopolizes everything. Exchanges dominate the control of nodes.
DFD SYSTEM seeks wisdom from the celestial bodies. The sun and the moon reflect each other, and the stars are everywhere. There are two kinds of nodes in DFD SYSTEM: sunlight node and starlight node. Sunlight nodes constitute the center of DFD SYSTEM network, with higher con-figuration and better processing making the net-work process faster. However, in order to avoid the monopoly of capital, each individual partici-pating in the network can become a starlight node by limited conditions. The block of DFD SYSTEM network needs to be verified by starlight node, which ensures that network will not be controlled by sunlight node, or monopolized by capital and syndicate.
DFD network encourages more witnesses to par-ticipate in the network construction. The greater the contribution of witnesses to the network computing power, the higher the level of starlight node. The daily block reward is put into the node mining pool, and users need to buy starlight miner to participate in node mining.
The Starlight mining machine is divided into seven levels. At the beginning of the project, users need to use USDT to purchase and acti-vate, and then the DFD purchase channel will be opened to anchor USDT with DFD real-time cur-rency price. For example, the level 2 miners below can be purchased using 100 USDT or DFD worth 100 USDT.
In the future, the community node will vote to select the node to open the DFD channel to pur-chase mining machines. The DFD used by users to purchase mining machines will be placed in the lock pool and will not enter the market. After all DFD mining releases are completed, the nodes will reach consensus Decide whether to release it and how to release it.
Each account can only hold one mining machine, and everyone can hold multiple mining machines at the same time by creating multiple accounts. At the same time, users can upgrade the existing mining machine to a higher-level mining ma-chine by making up the difference (the 6-level mining machine needs to reach the double-code hashing power to upgrade the 7-level mining machine, and the 1-5-level mining machine can be upgraded without restrictions) .
Mining rig upgrade formula:
Z=Y-(365-D)(X/365)Z is the fee for upgrade, X is the price of old mining rig, Y is the price of new mining rig, and D is the days of old mine rig being used.
For example, User A purchased a grade-4 mining rig by using 1000 USDT, and wanted to upgrade rig to grade 5 at the 100th day of mining, so ac-cording to the formula, the upgrade fee will be:
5000-(365-100)(1000/365)≈4274 USDT
Sunlight node
Sunlight Node Configuration Requirement
Parameter table of starlight miner
Calculation formula:
Node mining income =Node computing power of the day / Whole network computing power of the day * Block reward of the day
Computing power of node = Computing power of miner +Direct Computing power+ Spiral comput-ing power
After purchasing the miner, the miner's comput-ing power will take effect immediately. It will take a snapshot of the node's computing power and the whole network's computing power data at 24:00 every night, and distribute the income at 12:00 on the second day.
DFD SYSTEM has 10 Super nodes in total. When the voting ranking enters the top 9, a certain reward will be given. The top 9 sunlight nodes have the right to account and participate in the block generating.
As a distributed network server of DFD SYSTEM, sunlight node has the minimum hardware con-figuration requirements. If the participant's hard-ware fails to meet the standard, there may be dropout, crash or other problems, which will affect the reward income of the main node. Ac-cording to the program logic, the better the hard-ware configuration, the faster the network infor-mation transmission speed, and the more re-wards received. The sunlight node needs to pro-vide the underlying layer center of DFD SYSTEM network, and it needs to ensure continuous online services to continuously obtain DFD re-wards. Once sunlight node drops the line or goes offline, it must be reconnected in 10 blocks. If this sunlight node is not reconnected within 10 blocks, the main node will be removed from the sunlight node reward list. After reconnection, the system will bring the whole node back into the sunlight node list. If you don't miss the reward allocation when you re-enter the list, you can still get the reward for the sunlight node. However, if the reward allocation has ended, you need to wait for the next round. Each block allocates the income to 1sunight node.

Cross Chain
At present, a major contradiction in the block-chain industry is the problem of islands formed between multiple chains, which makes the eco-nomic cycle links between chains disconnected and the blockchain economy unable to be acti-vated. DFD SYSTEM considered the necessity of cross chain in its early stage.
Compared with the current mainstream cross chain scheme and the cross chain comprehen-sive performance, and considering the later scheme upgrade, DFD SYSTEM technical team has designed its own cross-chain scheme on the notary mechanism: free notary mechanism.
The mainstream cross chain solutions include:
Notary schemes
Sidechains/relays
Hash-locking
Distributed private key control
Notary schemes+ Side-chains Mixing technology
Structural diagram of cross chain scheme
Anchor nodes are scattered in the block-chain distributed network, and multiple sig-natures are used to reach a consensus;
The anchor node group is open to the public, and ordinary nodes can apply to become anchor nodes to provide services for cross chain transactions;
At the same time, the malicious nodes will be punished by disqualification.
If the main goal of the early cross chain scheme is asset transfer, the cross chain scheme of DFD SYSTEM is not only asset transfer, but also cross chain infrastructure. It mainly emphasizes that assets can be realized by smart contracts. DFD SYSTEM's cross chain technology aims to become a high-performance, decentralized cross chain infrastructure, access to a variety of cross chain applications at the same time, focusing on commercial landing. This cross chain scheme can make DFD system have strong advantages in the fields of finance, government chain, enter-prise blockchain solutions, etc., and help DFD SYSTEM technology ecosystem become a set of industrial blockchain solutions.
The cross chain structure includes notary mech-anism, with the main and sub chain to achieve efficient communication, through the notary mechanism to achieve cross chain assets. For example, the block head information of the DFD SYSTEM main chain can be written into the block of the DFD SYSTEM sub chain. The DFD SYSTEM main chain and the DFD SYSTEM sub chain use the same consensus verification method to real-ize the communication between the two chains. Through the notary mechanism, the trusted dis-tributed nodes (notary/node1 or notary/node2) are used to record and prove the transactions on the DFD SYSTEM main chain to the sub chain, and the communication realizes the cross-chain interaction of assets. In short, the DFD SYSTEM main chain and the DFD SYSTEM sub chain use the distributed node (node1 or node2) of the common trust as the notary. The DFD SYSTEM main chain and the DFD SYSTEM sub chain can indirectly trust and complete the asset ex-change.
The advantages of DFD SYSTEM cross chain scheme are as follows:
Decentralization
NOTARY/NODE1
Initiate cross chain transactions Collect/monitorcross chain information
Prevent rollback, multiple transactions

NOTARY/NODE1
NOTARY/NODE2 NOTARY/NODE1

NODE5 NODE5
Based on the direct transactions on the blockchain, the data is open, transparent, traceable and verifiable;
Cross chain program is open-source, com-munity can organize deployment sponta-neously, participate in service competition and support of cross chain transaction;
The blocks are anchored to each other, and the data of the whole network is intercon-nected;
Statistical analysis are made and the busi-ness data results of cross chain transac-tions are published regularly.
One-stop management of all assets on the chain by Cross Chain Wallet ;
The cross chain trading operation imitates exchange and is in line with the user habit with a large user base;
To complete a cross chain transaction, users only need to operate once;
The transaction cost is low.
Openness and transparency
Easiness to operate
Based on the decentralized multi-signature technology, the data can be transmitted credibly;
The signature uses elliptic curve key signa-ture which is difficult to crack.
The breakdown of some anchor nodes does not affect the normal cross chain transaction;
The interaction between chains is simple and the transaction efficiency is high.
Cross chain technology supports many to many cross chain deployment, which can realize resource intercommunication of multiple chains;
Based on the cross chain technology, the subchain can be released and integrated into the chain ecosystem;
Many subchain templates adopt main-stream consensus protocols to meet differ-ent business needs.
Safety and reliabil-ity
Strong expansion
LibP2P
iCloud information disclosure report
IPFS is short for Interplanetary File System, meaning that in the future, with the development of science and technology to a certain extent, IPFS is also used to transfer files between stars. It was initiated by Juan Benet in 2014. In 2015, a team called Y-Combinator, composed of 14 core developers and hundreds of code contributors, got a huge investment in the incubator competi-tion.
This file system can be understood as a hyper-media protocol, which is a large file divided into many copies and placed on different nodes (P2P). IPFS is a kind of content addressable, ver-sioned, point-to-point hypermedia distributed storage and transmission protocol. The goal is to surpass or even replace HTTP, connect all devic-es in the network through a file system, and build a faster, safer, more open and shared Internet.
DFD SYSTEM believes that the low-cost and high-speed storage scheme of IPFS must be the necessary infrastructure of decentralized appli-cation network in the future. IPFS network has both decentralization and low cost. In the digital life, people pay more and more attention to pri-vacy, and decentralized storage will become the necessity of people in the future. ICloud has been hacked to make nude photos of more than 50 Hollywood actress leaked. In the view of DFD SYSTEM, this is not an isolated case. As long as the storage of the Internet is still centralized, such things will continue to happen.
LibP2P module is built in DFD and it is used as the network layer of IPFS.
One node of LibP2P can connect with another node, which can use different transmission methods, including connection delay, communi-cation through different protocols, and negotia-tion according to the needs.
In IPFS, LibP2P module is mainly responsible for data transmission, such as routing, network, transport, etc.
LibP2P includes:
Transports
Discovery
Peer Routing
NAT Traversal
Content Routing
LibP2P brings together a variety of transport and peer-to-peer protocols, so that developers can easily build large and powerful P2P networks. It is not easy for developers to build a P2P net-work. The complex network environment, various communication protocols and network devices make it difficult to create large-scale peer-to-peer network. The main function of LibP2P is how to make different network modes transmit data to each other successfully. In short, the bottom layer of peer-to-peer transmis-sion protocol can meet the decentralized trans-mission requirements through LibP2P.
LibP2P is a set of point-to-point protocols to discover nodes, and connect them, as well as discover content, and transfer them. The whole IPFS is composed of LibP2P and other modules, and LibP2P is a modular network stack. The IPFS team separated the network layer of the peer-to-peer network from the IPFS project to form an independent project, which is LibP2P. This project can not only be used by IPFS, but also by other projects. It exists as the underlying protocol of P2P project. It proves that this proto-col is also very powerful and practical.
DFD SYSTEM is responsible for protecting the privacy and security of users' data, and will pro-vide Babel Tower users with a sustainable, effi-cient and low-cost storage scheme.
DFD Lend
For the holders of digital currency, they need to face the risks of public chain security, private key loss or operation error, and currency price fluctu-ation. The safe digital currency financing can give the holders some interest rates to reduce these risks.
The current DeFi ecosystem mainly supports users to manage the financial affairs of ETH and DAI. But the financial needs of many other public chains have not been met. In terms of market value, in particular, the market demand of BTC fi-nancing is 10 times that of ETH, and that of USDT financing is 65 times that of DAI. (based on data of June 2020).
There are two main matchmaking modes in the lending market, such as fund pool mode like Compund and P2P matchmaking mode like Dhrma. There is a classic problem in asset trad-ing in economics called "double demand coinci-dence". When circulation is insufficient, it takes time and effort to match supply and demand. Imagine that if you can't find a car online for half a day in a small city, you might as well use the local taxi call directly. In the early DeFi lending market, due to circulation problems, the fund pool mode is more suitable.
Due to the high fluctuation of the digital currency market, the flexibility of the lending cycle is very important. Most of the traditional centralized lending products give the initiative of the cycle to the user, and the lender can actively return the product within the cycle. And the they usually has a 10/15 /30 day lending cycle who can't deal with the pledged digital currency assets flexibly. Through the way of fund pool, the financing party can save and withdraw, borrow and return at anytime. Although such a model seemingly sacrifices the profit cycle of the financing par-ties. But when we lengthen the time coefficient and make it even, we actually get the same result.
For example, Allen lent ETH to Hans at an annual interest rate of 4%. The original loan period was one month, but Hans returned it within 15 days. Bob, on the other hand, save ETH in DFD lend at an annual rate of 2%. For Allen and Bob, what they end up getting is both a 2% annualized rate return.
DFD lend will be the first cross-chain lending agreement on the market.
Dpower
DFD Dex(Decentralized Exchange)
Because DFD SYSTEM supports cross chain function, when using DFD lend, mainstream digi-tal currency assets can directly enjoy DFD Lend's convenient services; both BTC and ETH will enjoy financial income at the moment of deposit and obtain DPower (asset lending value).
DFD Lend uses Dpower to manage the user bor-rowing limit. When the user deposits the asset into the fund pool, he will get the number of cur-rency * price * coefficient = Dpower. The price comes from DFD Lend's oracle. The coefficient is set according to the currency's circulation. For example, BTC is 75% and USDT is 80%. Dpower will adjust at any time according to the fluctua-tion of market price. The upper limit of Dpower is the upper limit of funds that users can borrow.
Centralized exchange is now the mainstream of blockchain industry, but there are various risks in centralized exchange. Two of the biggest risks are hacking and exchange misappropriating user assets. In the past decade, there have been hun-dreds of exchange hacking, except for Mt.Gox And Coincheck earlier, and Upbit of South Korea recently. These are usually tens of millions of dollars theft. It is also a major risk for the ex-change to misappropriate user assets. In 2019, Fcoin, the head exchange of the blockchain in-dustry, had a huge deficit at the beginning of its establishment, but it was exposed that it’s not able to withdraw money until 2020. Before that, user asset has been misappropriated by Fcoin.
But due to the problems of speed and usability, decentralized exchanges have not become the mainstream of the market.
However, it will be solved in DFD SYSTEM. Based on the high TPS characteristics of it, Dex(decen-tralized exchange) has the technical perfor-mance not inferior to Cex (centralized exchange). Because Dex solves the security problem of user assets, it is bound to become the mainstream.

DFD Margin(Derivative Exchange)
For example, if you place an order on the ETH chain, sell ETH, and buy EOS, the order will be collected to DFD SYSTEM IBC. When the order matching is successful, EOS will be transferred to the EOS wallet you set.
Transaction contract information such as ETH/EOS/TRX on DFD Dex is open-source, and users can view the situation of capital lock posi-tion and order information flow at any time.
For public chains like BTC that do not support smart contracts, or public chains with slow speed, assets can be mapped first and then traded cross chain through DFD. For users, assets in any chain can be traded directly.
According to data of AlETHio , 38% of Uniswap users are also users of MakerDAO. For DFD SYSTEM, it is a reasonable choice to combine the DFD Lend's capital pool circulation and DFD DEX's trading circulation, and then develop a leverage trading product DFD Margin.
The existence of DFD Margin expands the appli-cation scenarios of DFD Lend, and provides more circulation for DFD Dex.
At present, there are two modes of decentralized exchange: automatic market making mode and order book mode. The order book mode can be divided into the on-chain order book mode and the off-chain order book mode. Although auto-matic market making mode, such as Uniswap, can solve the circulation problem, it lacks the most important price discovery function for transactions. And for large orders, we can not ideally require the capital pool to grow at any time to adapt to large orders. The on-chain order book, because it is recorded on the chain, re-stricted by the performance of the public chain, the matching speed is very low, and the problem of Gas war or double-spending in one order will be encountered.
DFD Dex adopts the mode of off-chain order book, with under-chain matching and on-chain clearing, which can perfectly avoid the defects of the above two modes. It improves the circulation of the system through circulation nodes.
Compared with the current Dex, DFD Dex can support the circulation of all digital currencies. You can purchase assets of other chains in any chain.

Margin Closeout Mechanism
Private ChatIn the centralized network, all our social informa-tion and identity information are stored in the centralized server. Once the centralized server is attacked or used, our privacy information will be used in various business, political and criminal activities. Both WhatsApp in the West and Wechat in China are regulated by the govern-ment.
In the mainstream mode, the communication be-tween the client and the server is indeed en-crypted, but the server itself can get the original information. Now Alice wants to send a message to Bob. Alice encrypts the message on her mobile phone and then sends it to the server. When the server sends the message to Bob, it s it first and then sends it to Bob. So all the messag-es transmitted on the network are indeed en-crypted. But note that the encryption channel is established between the client and the server, which means that the server is the receiver, and the server can decrypt the message to obtain the original text. Normally, in order to make use of big data to obtain business profits, or to meet the monitoring needs of relevant departments, the company will ensure that it can obtain clear text information on the server. This is the biggest security hole in the whole communication pro-cess. As long as the attacker takes the server, he can get the communication records of hundreds of millions of people for many years at a time, and search all kinds of important private data at will.
At present, most of the leverage trade DeFi prod-ucts need to lend first. DFD Margin supports the way of matching=lending and borrowing. That is, when the order matching is successful, DFD margin will borrow money from DFD Lend, which can help users save interest. If encountering ex-treme market, users may face higher interest, or even can't borrow coins.
DFD Margin and DFD Lend share the margin Closeout mechanism. The difference is that the funds borrowed through DFD Lend will go to the user's wallet, while the money borrowed through DFD margin is locked in the contract. With this mechanism, users can use their own funds more flexibly as long as they meet:
When meeting this condition, direct clearing will be carried out according to the clearing mode of DFD Lend.
You can cash your wallet at any time.
The price of margin closeout is:
One Stop
Trading Experience
Most of the existing DeFi products can't provide a one-stop trading experience. Users need to op-erate first, borrow money for trading, and then trade. When trading through DFD Margin, the lending function can be used directly when plac-ing an order. Because DFD Margin is connected to the fund pool of DFD Lend in the background, in most cases, users do not need to worry about the funds (the increase of interest rate will make more funds to flow into the fund pool).

DFD SYSTEM private chat adopts end-to-end en-cryption(E2EE). Information is encrypted on the sender's client, like Alice's mobile phone, while only the receiver, like Bob's mobile phone, can decrypt it.
Through the use of E2EE, data is only stored in the local network, only through the DFD SYSTEM for transfer distributed transmission. Even though through DFD SYSTEM to transfer, DFD SYSTEM banned the possibility of user privacy disclosure. With the sunlight nodes on the DFD SYSTEM chain making up the distributed anony-mous center, a distributed anonymous network is established. However, the center does not have absolute control, as starlight nodes act as a balance to ensure the security of DFD SYSTEM information network. Sunlight node and starlight node constitute the distributed anonymous net-work of DFD SYSTEM. Through DFD SYSTEM network, no matter what kind of information can be transferred safely, and the final storage is only in the user's local device. No one can get any in-formation except the two sides of the communi-cation.
Fkey is the only key for private chat using DFD SYSTEM, and there is no possibility of user infor-mation disclosure because no personal KYC (know your customer) is required.
The digital currency itself has high fluctuation, and DFD can not avoid this characteristic as well. Especially when DFD SYSTEM has done a lot of empowerment for DFD, and people have certain expectations for stable storage of wealth, so stablecoins is almost an indispensable part of decentralized financial ecological public chain.
From the whole development of digital currency, we can see the importance of stable currency. The mainstream stable currency USDT has been issued continuously since it was issued, and now it has been ranked among the top three in the market value of digital currency.

Anonymous Payment
There are two mainstream stablecoin issuance schemes: centralized issuance and mortgage is-suance.
In addition to the USDT issued by Tether, there are Gemini Dollar issued by Gemini and Paxos standard issued by Paxos, are all stablecoins. USDT occupies half of the current market due to its advantage of issuing the first. However, the issuance risk of USDT has always been criti-cized. Deception of USDT has been regarded as the biggest potential black swan event in the blockchain industry, and Tether has not dis-closed the specific property situation to confirm its cashing capacity.
The stablecoins issued by mortgage mainly in-clude DAI of MakerDao. DAI is obtained by over 200% mortgage on ETH and smart contract pric-ing. Due to the existence of excess collateral with , the value of DAI is guaranteed. This kind of issuance is no different from that of legal curren-cy by mortgage on gold.
DFD SYSTEM adopts decentralized excess col-lateralized issuance. By pledging DFD, BTC and ETH, DUSD and DRMB can be obtained, and more digital legal currencies will be supported in the future. DFiat is the digital legal currency on DFD SYSTEM, which is an important part of DFD SYSTEM ecosystem, and also an essential value transmission intermediary of DFD SYSTEM busi-ness and financial ecosystem. In the future, DFiat will become a general ‘free currency’ in the decentralized global financial activities.

Zeroknowledge proofconsists of four parts:
zkSNARK
zkSNARK is the abbreviation of zero-knowledge succint non-interactive arguments of knowledg:
Zero knowledge - zero knowledge proof.
Succinctness - the evidence information is short and easy to verify.
Non interactivity - there is little interaction, and the certifier basically provides a string to verifi-cate. For blockchain, this is crucial, because it means that the message can be put on the chain for public verification.
Arguments -- the proving process is computa-tionally sound, and the prover can't make false evidence (crack) in a reasonable time. Perfect soundness corresponds to computationally soundness, which is generally required in cryp-tography.
Of knowledge - it is impossible for a prover to construct an effective zero knowledge proof without the specific witness .
Transformation of the polynomial problem -- the problem to be proved is transformed into the polynomial problem t(x)h(x) = w(x)v(x). The prover submits the proof to make the verifier confirm that the polynomial is true.
Random selection verification - the value s of random selection verification, verifying t(s)h(s) = w(s)v(s). Compared with the polynomial equiva-lent t(x)h(x) = w(x)v(x), random selection verifi-cation is simple and has fewer verification data. The security of random selection verification is certainly not as good as polynomial equation verification, but if it is with enough randomness, it is secure enough.
Due to the transparency of the blockchain, we can trace to a particular transaction by associat-ing multiple nodes in the blockchain. Then, by analyzing the blockchain data and KYC/AML data, we will know who sent the transaction, or even more details, such as location, transaction reason, etc. As the government pays more and more attention to the field of digital currency, more big data analysis companies like Chainaly-sis are using the transparency of blockchain to destroy its anonymity and its inherent freedom which is against the original intention of Naka-moto to create BTC.
When BTC was first created, anonymity made it have a good privacy payment feature. But with the development of big data technology, the transparency of BTC in turn destroys its ano-nymity. It's like the evolution of spears and shields. While the common chain needs to be upgraded. DFD SYSTEM knows people's inner needs for anonymous payment. DFD system brings zero knowledge proof-zkSNARK.
Decentralized Gambling
But the traditional online gambling can't prove itself fair. This means that websites can't cheat you by picking winners they like. All winners were randomly selected. All games on DFD SYSTEM are completely transparent and verifi-able. They run through smart contracts and are maintained by DFD SYSTEM nodes. When a block is released, the game developer cannot modify any part of it.
Decentralized gambling uses three parameters to calculate each game -- server seed, client seed, and nonce. The game developer opens the client seed and nonce to the user, which will be used for the next throw together with the hash data of the server seed. The server seed is the only part that is kept secret until the dice are rolled. Then, after the user throws, the developer will send a receipt to the user, which shows the server seed used, and the user can verify that this is the server seed that the user said to use before scrolling by checking whether the hash of the seed matches the hash displayed to the user by the developer before scrolling.
Homomorphic hiding - homomorphic hiding refers to a feature of the function. Input calcula-tion and output calculation remain 'homomor-phic'. Taking additive homomorphism as an ex-ample, a function E (x) satisfying the following three conditions is called additive homomor-phism:
Zero knowledge - there is no other knowledge between the prover and the verifier except 'whether the problem is proved or not' (random selection value, polynomial calculation result of selection value, etc.).
Through DFD system, users can choose either public broadcasting like BTC or completely hide the target transaction information of both parties when making payment, and realize absolute ano-nymity through zkSNARK. This kind of full free choice is completely handed over to the user. Since then, more application possibilities have been fully developed, and zkSNARK has become the shield of the upgraded version to give users absolute security and no worries.
There are different legal definitions of gambling in different countries. The existence of Las Vegas, Atlantic City, Monte Carlo and Macao proves the rationality of gambling legally which depends on how the powerful release the fran-chise. Welfare lottery, sports lottery and stock, which are officially licensed, are also gambling in a broad sense.
Although there are different definitions of gam-bling in some countries, gambling is rooted in human nature. Every year, only the Sun City online gambling platform gambles more than one trillion yuan. What DFD SYSTEM should do is to release human nature, release privilege, and make Caesar's belong to Caesar, people's belong to people. People are not children and they don't need to be disciplined. Prohibition does not mean that it does not exist. It will always sprout and take root in different places.
Online gambling includes poker, casino games, sports betting, bingo games and lotteries, etc.. Among them, casino games and sports betting occupy the largest market share. Casino games include roulette, dice and slot machines. It has been pointed out that the number of online gam-bling will reach US $59.79 billion in 2022.
1. Given E(x), it is difficult to derive x;
2. Different input corresponds to different output;
3. E(x + y) can be calculated by E(x), E(y). Multi-plicative homomorphism is similar.

BlockchainBusiness Ecosystem
Through technical guarantee, combined with stablecoin, DFD SYSTEM decentralized gambling can provide users with a new experience. This is also a trillion level market. DFD system is a bor-derless financial center. All the options rights are returned to users. What DFD SYSTEM needs to do is to build the underlying conditions that are most suitable for all kinds of applications. When this market is reached, it will bring DFD a hun-dred times value growth.
The era of hypermarkets and television advertis-ing has long passed, and electronic payments and social media are already bases. In the 1990s, the most effective means of communica-tion was five seconds after taking a weather forecast at the cost of 100 million yuan. In 2020, words, pictures, videos, short videos, live videos and other information are around consumers, with brand and information completely overload-ed, making the trust between people the most simple and efficient solution.
If you want to buy a box of eyeshadow, no longer rely solely on the recommendation of the sales-person or the celebrity endorsement, but refer to the sharing of the ordinary people on the social media; if you want to buy clothes, no longer wait for the discount season, but contact familiar on WeChat. The role of disseminating information is no longer just the KOL (Key Opinion Leader), but the KOC (Key Opinion Consumer) around you, who may be your relatives and friends, the trust-ed overseas purchase agent or micro business on Wechat. And more importantly, they are also the consumers of commodities who frequently interact with you, understand your real needs, and share reliable solutions.
A variant of KOC in 2020 is live KOL. China's live KOL makes Weiya and Li Jiaqi become the A-listers. In the long time with fans and prod-ucts, the anchor has established a unique sense of trust, which is fully reflected in performance.
Relationship and trust become the first produc-tivity. Thanks to the strong social network estab-lished by Babel Tower and private chat, DFD SYSTEM has a natural chain business ecosys-tem, and the door of the new economy is open here.
Merchants around the world can register the col-lection address on the DFD SYSTEM chain, set the commission rate of the smart contract, and activate the chain merchant contract. Through these smart contracts, businesses register their own collection address under their Babel system, set the distribution ratio of contract Commis-sion, and create their own blockchain consensus sales network.
If all Fkey users in Babel Tower vein consume in the merchants who activate the chain merchant contract, then many Fkeys upward which are di-rectly connected in this Fkey can obtain the chain merchant contract Commission of the merchants.
This design greatly enhances the product pro-motion ability, because in Babel vein, any user with guiding relationship can get commission sharing. For more commission, Babel Tower users will try their best to promote product, and business joining Babel Tower can easily get a consistent and huge sales team. Although Babel Tower records infinite levels, it does not bring in-finite levels of burden to businesses. Businesses can customize the level of sales team according to their own needs, select the level with the most economic value, and maximize the sales force.
Although the traditional social communication software has been embedded in the payment system, it does not have a business system that is convenient for business management. DFD SYSTEM blockchain business ecosystem has built-in business management system, which seamlessly connects the interpersonal connec-tion established by private chat. Merchants can directly manage product sales through DFD system blockchain business function, and attract Babel vein for rapid promotion by attractive Commission settings.
In the traditional business ecology, this kind of business promotion vein is called dark vein, which is not used by the business in the open channels. The formation of dark vein depends entirely on human connections. But the estab-lishment of the network can't achieve shallow performance because of the destruction of trust. Through the Babel vein of DFD system, these are not problems at all, as the dark vein can be used by any business. Through Babel vein, business can operate faster. A huge commercial empire is established here.
Through blockchain business contracts, busi-nesses and exchanges can complete transac-tions without trust. Smart contracts and atomic exchanges can ensure the exchange of goods and funds at any time. When disputes arise be-tween businesses and users, they can be arbi-trated through DFD SYSTEM arbitration commit-tee.
DecentralizedGovernance
The vision of DFD SYSTEM is to establish a truly decentralized financial ecosystem. In such eco-system, DFD SYSTEM officials must not be the rulers in another sense, which is nothing differ-ent from the former 'reincarnation”.
The reason why the cryptocurrency community is so powerful is decentralization. Because there is no center, everyone can participate in commu-nity autonomy. Because there is no center, no center can be destroyed. Because there is no center, everyone is the owner of the system. BTC is powerful due to the vanish of Satoshi Naka-moto, the founder of BTC, which makes it a real over sovereign currency. As there is no manipu-lator, everyone is a manipulator.
DFD SYSTEM has a deep understanding of the significance of decentralization, so DFD SYSTEM team is only the initiator of the early stage of the project to promote the early development, but the real long-term great development of DFD SYSTEM depends on the community. In the DFD SYSTEM ecology, the community is the most im-portant role, which determines everything. The DFD SYSTEM team, as the early executor, assists in the management of community proposals and the implementation of community voted propos-als.
DFD SYSTEM team/sunlight node/starlight node can launch all proposals on DFD SYSTEM, in-cluding adjusting various coefficients in the system and future public chain planning. In order to avoid the waste proposal, the proposal needs to consume a certain amount of DFD as the cost, which will burn directly. After the proposal, both sunlight node and starlight node can vote on the proposal. The voting will be weighted according to different weights. After weighting, if the affir-mative votes exceed the negative votes, the pro-posal will be implemented by the foundation.
Although sunlight node plays a key role in the whole network, due to the requirements of de-centralized governance, the overall voting weight of sunlight node does not exceed that of starlight node.
In order to ensure the limited im-plementation of governance, we put some restrictions on the Fkey:
DFD SYSTEMToken Distribution
Address must hold more than 10 DFDs;
The address must hold more than 10240 blocks of DFD;
The address should be at least starlight level 1 node.
Two-way voting mechanism is adopted, which is either agreeing or disagreeing. Only when the weight of the agree vote ex-ceeds the disagree vote can the proposal be finally passed.
Based on the decentralized governance of DFD system, DFD system will no longer fall into endless public chain branches, and DFD SYSTEM will be a self evolving public chain.
The token of DFD SYSTEM is named DFD, and the total issued amount is 84 million. The distri-bution is as follows:
At present, a total of 16.8 million tokens are used for the construction of sunlight node, which will not flow to the market. In fact, DFD SYSTEM is a '0 pre mining' public chain, realizing absolute fairness. Any user who wants to get more DFD tokens needs to buy DFD tokens to join the DFD SYSTEM ecosystem first. In terms of distribution mechanism, DFD system ensures that it won’t occur that previous blockchain project rips the users off. All users are in the position when they join the DFD system ecosystem. The height of DFD depends on users' recognition.

Block Rewardand Reduction
by Half MechanismDFD system generated one block about every 3 seconds. At any time, only one producer is au-thorized to generate blocks. If the block is not successfully generated at a certain time, the block is skipped.
Block generation in DFD SYSTEM takes 10 blocks as a cycle. Producers mix based on random numbers derived from block time, in order to ensure that the connection between the blockers is as balanced as possible. If the block generator misses a block and no block has been generated in the last 24 hours, the generator will be deleted. This ensures the smooth operation of the network.
Under normal circumstances, DFD system will not experience any crossover, because block generators cooperate to produce blocks rather than compete. If there is a block branch, the con-sensus will automatically switch to the longest chain. The length of a blockchain with more gen-erators will grow faster than that with fewer gen-erators. In addition, no block generators should produce blocks on two blockchain branches at the same time. If a block generator is found out to do so, it may be eliminated.
The reward of DFD SYSTEM block is 3 DFD coins. Every day, the DFD SYSTEM will produce 86400 coins. Every 90 days is a stage, and the produc-tion of each stage will be reduced by 50%. Tokens generated by block rewards will be used for node mining rewards.
All applications based on DFD will consume DFD as a handling fee. In the early stage of DFD SYSTEM, block rewards will appear to hurt the inflation of the economy greatly. However, since DFD SYSTEM is almost zero flowing at the be-ginning, its upper limit boundary depends entire-ly on people's confidence in it.
For all the applications on DFD system, the han-dling fees consumed by users will burn directly. The infinite expansion of the application bound-ary of DFD system brought the huge demand. DFD system is an infinite deflation model.

Developer Ecosystem
DFD SYSTEM will set up a developer ecosystem fund and make incentive policies to encourage independent developers on DFD SYSTEM in the way of some certificates.
Community is most powerful. Internet technolo-gy has always advocated open source and open-ness. In the non-commercial environment, how-ever, there are often smarter ideas, DFD SYSTEM plans to hold a developer competition every 1-2 years in the world in either Europe, North Ameri-ca, Hong Kong or Tokyo, hoping that more excel-lent applications will be generated through the developer competition, and the underlying tech-nology of DFD SYSTEM will also be presented to the global blockchain practitioners, so that more people will pay attention to it, so as to form a stronger application ecosystem for blockchain developers.
DFD SYSTEM is expected to be used for develop-er ecosystem fund and developer competition, with an amount of US $1 million annually, which will be modified according to DFD SYSTEM oper-ation and community voting.
Although DFD SYSTEM has built-in decentralized exchanges, more exchanges will put DFD on the market, which will benefit its global circulation. DFD SYSTEM welcomes the cooperation of ex-changes all over the world. The first batch of white list exchanges supported by DFD token are as follows:
