I. Project background

1. Overview of DEFI

Defi (Decentralized Finance), also known as Distributed Finance. Defi is a variety of financial applications built on the chain based on blockchain technology and cryptocurrency and using distributed ledger technology. Defi's innovative revolution Defi is known as the "new financial revolution movement". Compared with traditional finance, DEFI provides different levels of innovation in terms of technology, operation model and so on. DeFi as built on block chain network financial ecology, natural with decentralized attributes, that is to say, DeFi use technology to replace centralized authority credit block chain and arbitration procedures, without relying on any centralized subject offering credit and endorsed, complete financial planning and capital flow agreements, make the whole execution process open and transparent, Improve the efficiency of financial services and reduce the cost of credit. Defi lowers the barrier to contribution so that anyone can build new Defi applications based on a decentralized network and contribute to the ecosystem; Defi provides transparency and security for traditional financial applications. No third party can block or reverse any transaction, all transaction records are accessible on the chain, and the user has complete control over his or her funds.

2 Overview of NFT

An overview of NFT non-homogeneous tokens

NFT (Non-Fungible Token), a non-homogeneous Token, is a new type of crypto digital asset. The English word Fungible is used to describe a good that "has the same value as a single unit", a good or a good has the same property, each unit has the same value and can be exchanged for another good or token of the same type. For example, a bitcoin has the same value and properties regardless of its owner. Non-homogenization refers to the unique and irreplaceable goods. Each commodity is unique and has the property of not being convertible. For example, domain name, art, cell phone number, real estate, etc. Each non-homogeneous token NFT has its own characteristics and attributes. NFT has become a new digital economy application in the blockchain network, involving content including art, card, pet collection, game props, tickets, identity ID, virtual real estate, etc., and NFT has become the proof of authenticity and ownership in the digital field. The space presented by these application scenarios allows blockchain technology to have more imagination combined with financial scenarios. NFT is known as "the nearest entry of blockchain application landing".

3. The application of NFT

The first NFT application in the crypto market was CryptoKitties, the crypto cat that exploded across the web in 2017. Crypto Cat is the world's first blockchain game released on the Ethereum public chain, causing congestion on the Ethereum network for a time. 1.5 million CryptoCat users contributed $40 million worth of transactions. The slogan of the website of Crypto Cat is "Every Crypto Cat is unique". The internal parameters and data of the same type of Crypto Cat are different. Therefore, Crypto Cat has the characteristics of non-homogeneous NFT tokens. In addition to blockchain games, NFT non-homogenized tokens are gradually applied in more scenarios to ensure the permanent ownership of trophies and the authenticity of value of participants. Since 2020, NFT applications have been greatly upgraded and expanded to achieve the following applications:

A. Art NFT. According to statistics, the global circulation capital volume of the art market is about 70 billion dollars every year, among which counterfeit and pirated works of art account for 20%-50%. By digitizing the ownership of works of art through NFT, artists own the copyright of their works of art in the encrypted world. The copyright and ownership are no longer dependent on third party protection to ensure the digital art


B. NFT for entertainment products. The traditional entertainment industry has huge digital ownership issues, and NFT is redefining the traditional form of entertainment product distribution. Using NFT to distribute works such as music, without any third party deployment, allows musicians and others to create digital goods themselves and sell them, which can only be enjoyed by the users who hold the NFT token of the work, thus better protecting copyright.

C. Decentralization of physical assets and physical goods. Real estate, land, stocks and other real assets will be converted into NFT, trading, trading on the blockchain network; Or combine physical goods like T-shirts and hoodies with virtual items.

D. Domain name NFT is a very valuable event, and domain names with a high price of 230 ETH have been sold in Unstoppabledomains. Event tickets, domain names, sports periphery, insurance industry and so on can all be transformed in the form of NFT to realize the digitization of copyright and property rights and ensure the security and transparency of transactions.

Among all NFT usage scenarios, the development of DEFI has given rise to another new NFT scenario, DEFI +NFT, which stands for DecENTRalized Finance + Non-homogeneous Token, which is a very meaningful thing.

4.Defi +NFT financial system

According to the above introduction and description, the combination of NFT with another domain will give it uniqueness while ensuring cryptographic security. Non-homogenization attributes also bring natural scarcity to each NFT. Therefore, the value of the "combination" given by NFT makes it not only applicable to the above mentioned scenario. Defi +NFT realizes the completion of value management in smart contracts, which extends the value and significance of financial instruments in the blockchain network. Defi +NFT innovations currently available on the market include, NFT decentralized exchange Rarible; Aavegotchi, a decentralized collection game that combines NFT and DEFI; NFT ownership lending platform NFTFI, etc. These different levels and areas of innovation means that the possibility of the combination of DEFI and NFT is still in the early stage of exploration, with NFT products gradually out of the "entertainment collection" ecology, the market has more and more expectations and expectations of the financial system of DEFI +NFT.


1. Profile of DBK

DE-Centralized Bank (DBK) This is a blockchain-based super defense system, including banking, insurance, securities and trust, NFT and other application scenarios.

2. The advantages of DBK

A, DBK tokens, on behalf of the bank system automatically cast high low suck, traditional banking assets deposited in the paper proves that, in order to gain a small amount of annual earnings, and DBK is DBK tokens for financial products, and deposit assets for the TRX digital assets, constantly all the time between the mutual exchange, liquidity, every exchange, will produce a fee, The amount is much larger than the annual return of traditional banks. When a person occupies the corresponding token share or DBK-TRX in the liquidity pool or the bank, the more active the transaction volume is every day, the more the return will be generated, and the longer the deposit time in the bank is approaching the limit, the return will be several times of the principal.

As the transaction volume increases, the price of DBK financial token increases continuously. If the transaction volume remains unchanged, in the flow pool DBK-TRX, if TRX increases alone, the price of DBK token will also increase with the product of the coin quantity. If the transaction volume also increases, that is, the DBK growth rate is the product of the two.

C. The coin address affects the coin price, and the coin address is equal to the consensus number. The more people agree, the rarer the token.

3. The DBK dig

In the bank, DBK can be used for mining. When the bank is developed and stable, each customer in the flow pool can pledge DBK-TRX to carry out the side chain of DBK's late issue. Shareholders will have additional air drops for the currency holders who are always loyal to the bank and have made contributions. To achieve cross-chain, main chain ecological asset swaps, and accelerated increase of assets.

III. Token information

1.DBK issuance of 100 billion, never additional issuance, all circulation, no private placement, no pre-digging, no reservation.

IV. Future Vision

Get more people involved and put their assets in the bank to get multiple and long-term returns. As DEFI continues to expand, we hope to build a simple, sophisticated, convenient and fun new financial system that can operate across chains, inject new vitality into the crypto world and bring unique benefits to participants. DBK yearn for the combined development and application of DEFI +NFT+ cross-chain. The addition of NFT can build a unique community culture, and can link the physical assets in the real world. The price of DeFi

An exploration of value innovation, to guide DEFI to a sustainable development path, let history to witness the value of the bank, so that every believer can obtain the long-term benefits brought by this financial revolution.

V. Decentralization of banking institutions

1. What is distributed banking like?

Distributed banking has emerged in the wake of the digital currency boom. This is because digital currencies are the first smart assets to create a tool. For this reason, many people refer to distributed banking as "crypto banking." Crypto banking is a distributed platform that provides the same usual services as a central bank, mainly loan servicing and credit scoring, but essentially eliminates all the middlemen used by a central bank." Through smart contracts and peer-to-peer services, an environment that previously required bank approvals for loans and structured finance data has been transformed into an encrypted banking ecosystem. At the moment, most of the Internet is online because all problems can be solved online. Whether on a desktop computer or mobile phone, "banking" takes the form of a computer interface, and the money it handles is mostly digital.

2. How is this different from distributed trading?

Distributed exchanges, or DEX, exchange currencies, while distributed banking exchanges credit and trust.

Dex is also a new concept that uses peer-to-peer transactions between users who want to trade currencies. For example, if Alice wants to sell six bitcoins for five bitcoins and Bob wants to sell five bitcoins for six bitcoins, the Dex exchange will execute the transaction without a middleman. Crypto banking uses distributed P2P transactions in the same way, but for lending. While the lending process sounds much more complicated, crypto banking aims to automate the process and trade as quickly as a Dex exchange.

3. What technologies do crypto banks use?

P2P, blockchain, digital currency, machine learning, big data, and smart contracts are used in crypto banking. Peer-to-peer (P2P). The participants are private users, not banking institutions. Crypto banks connect a qualified borrower with a lender. P2P goes beyond the bureaucratic process that many centralised banks need to go through to approve loans. Block chain. All transactions are recorded on the blockchain. It's a transparent, immutable ledger that will provide users with data and use artificial intelligence algorithms to match appropriate borrowers and lenders. Machine learning big data. These technologies help automate the lending process and reduce bureaucracy. Artificial intelligence can work around the clock to match borrowers and lenders.

Digital currency. In distributed banking, where encryption operates more smoothly, it will be the only future for the industry. These distributed currencies have the blockchain language and maintain a perfect record of asset transactions.

Smart contracts. In crypto banking, smart contracts are used for a variety of purposes, such as converting currencies, establishing contracts between two parties, and automatically transferring funds between borrowers and lenders.

4. Do crypto banks have their own currency?

There is. Native digital currencies are helping to globalize banking.

For example, Datarius, the first P2P crypto bank, uses its own token, DTRC, for all transactions. This helps create a standard for a global payment system in the P2P lending process. Tokens can be easily converted into other digital currencies. Cryptobank's own digital currency has blockchain language, creating momentum for currency appreciation. It gives the tokens practical utility; This is an important part of the blueprint.

5. How safe are P2P loans? Can machine learning really match lenders' criteria to find the right borrowers?

While the process is automated, there are plenty of switching features that allow both borrowers and lenders to control it.

In the firm's model, borrowers are divided into three different types, ranging from minimally certified borrowers to fully transparent borrowers, who pass a risk management review. People with low credit can consider higher interest rates and build credit, while those with high credit can seek lower interest rates. But these interest rates are actually set by the lender, leading to the emergence of new interest rates based on the interaction between the two parties in the distributed banking industry using P2P.

6. What is social lending?

Social lending uses many aspects of a borrower to determine their score.

In addition to borrowers' credit scores, crypto banks can use big data and artificial intelligence to learn about their creditworthiness in other ways. Credit limits, credit management, and user ratings will help AI decide whether the borrower is eligible to borrow.

In particular, credit limits, for example, can automatically withdraw some funds from your wallet based on your needs.

This will allow microfinance to be automated. From this foundation came the so-called "credit card", which automatically drew some money from the credit limit when you ran low on funds. This is one of the great things about social -- you can "trust" every user of the system.

7. What other AIDS can machine learning offer?

In distributed banking systems, AI can contribute in many ways, including fraud, predictive scoring, and computing. Combat fraud. Tracking suspicious transactions and manual ratings; Searching for unreliable users through automated systems with high probability of completion. That's one reason Daritus socialized their rating system. AI helps debunk scams and provides users with space outside of credit.
