ADFs: the way to decentralize Finance
1. Enjin (enj)
in the near future, the game instry is the instry most likely to adopt blockchain on a large scale. Enjin coin is the cryptocurrency of virtual goods created by Enjin. Enjin is the "largest online gaming community platform" with more than 250000 gaming communities and 18.7 million registered gamers
Cardano (ADA)compared with Ethereum, EOS and Tron, Cardano is the third generation of decentralized app (DAPP) and smart contract platform. Cardano's design philosophy has the following points:
scalability: with the growth of users, the transaction processing speed is not affected or even faster, such as P2P protocol
interoperability: in the future, there will be countless devices connected to each other, instead of only connecting and forwarding through routers. All kinds of devices can communicate directly through standard general protocol
Sustainability: like bitcoin, Cardano project will not be controlled and influenced by a certain company or organization, which is a safe, decentralized and sustainable development platform
With the popularity of sto (security token offers), Nash also plays an important role. Nash is a kind of registered security token. In the past, Nash participated in and led the development of many projectsNash exchange is a decentralized exchange. If you hold nex token, you can calculate the dividend here
4. Basic attention token (BAT)
bat mainly solves the problem of advertising:
user information is abused: large companies such as Google and Facebook track and use user information and behavior, and sell without the knowledge of users
the effect of advertising is restrained: middlemen earn most of the fees, a large number of advertisements are blocked by users using software, and advertisements are fake
in the past six to 12 months, the number of publishers using the brand browser (Note: the brand browser supports bat token) has grown rapidly, and almost no blockchain ecosystem has grown so fast
5, chainlink (link)
chainlink mainly solves the problem that each blockchain has and the smart contract cannot obtain external data. In order to introce external data into the blockchain, the concept of Oracle is proposed in smart contract
companies including Google are supporting the development of chainlink. Here is a list of chainlink partners
one of the main problems of chainlink is similar to Ethereum. The development team has reserved 650 million link tokens, while only 350 million are in circulation at present
Ethereum (ETH)Ethereum has long occupied the second place in the top 100 cryptocurrencies. Its ecology is so big that we can't call it altcoin now. To tell you the truth, I'm not optimistic about Ethereum in the long run, but it will flourish in the short run
users in the defi ecosystem have complete control over the assets and participate in the defi with the help of P2P network and DAPP
advantages of defi
the popularity of defi is inseparable from its unique advantages. Defi mainly includes:
1. Open loan agreement
compared with the traditional credit structure, open and decentralized loans have many advantages, including integration of digital asset lending, digital asset mortgage, real-time transaction settlement and novel secured loan methods, no credit check, standardization and interoperability. The purpose of secured lending using open protocols such as maker and Dharma is to rece the risk of counterparties without intermediation by relying on the minimum amount of collateral provided by Ethereum
2. Issuance platform and investment
famous securities issuance platforms such as polymath and harbor provide the framework, tools and resources for issuers to issue marked securities on the blockchain. They have prepared their own standardized token contracts for securities (i.e. st-20 and r-token), which are unique in terms of automatic compliance and customizable transaction parameters and can meet regulatory requirements. Similarly, they are integrated with service providers (e.g., broker dealers, custodians, legal entities, etc.) to assist issuers in issuing
3. Decentralized forecasting market
decentralized forecasting market is one of the most attractive components of open finance, which is highly complex but has great potential. August launched the anti censorship forecast market last year, and other platforms like gnosis began to follow suit. Forecasting market has long been a popular financial tool for avoiding risks and speculating on world events, and decentralized forecasting market can also do this
4 exchanges and open markets
exchanges in open finance mainly consider decentralized exchange (DEX) protocol and P2P market. First of all, DEX is a P2P asset exchange between two parties on Ethereum, in which no third party acts as an intermediary, such as coinbase or other centralized exchanges. DEX also uses some highly innovative methods to exchange tokens, such as atomic exchange and other unmanaged methods, to exchange one asset for another with minimal settlement time or risk. The most popular DAPP in Ethereum is the decentralized exchange IDEX. Although many "DEX" claim that they are indeed decentralized or unmanaged, be careful before using them. The P2P market on Ethereum has great long-term potential, and may eventually cover the market of local digital assets and marked real-world assets
5. Stable currency
stable currency is booming in the digital asset market by issuing warrants, auditing its reserves and managing its price linked new model. Stable currency is just a token issued by the blockchain, which aims to keep a stable link with external assets (mainly US dollars, gold or other assets). The stable currency of encrypted mortgage includes Maker & # 39; S Dai, where the underlying asset (e.g., ETH) is over mortgaged relative to the borrowing asset (DAI) according to the current mortgage rate. So far, stable currencies backed by legal tender are the most popular because of regulatory compliance and no audit risk, such as tether, usdc and Gemini dollars
disadvantages of defi
on the one hand, the development of defi is restricted by the performance of the underlying public chain. The current defi project is mainly built on the Ethereum network. At present, the performance bottleneck of Ethereum is relatively prominent, and there is still a long way to go to break through the bottleneck. Under such a situation, those projects with high performance requirements will be in an embarrassing situation. On the other hand, compared with traditional financial procts, decentralized financial projects are much more difficult to use and have higher cognitive requirements for users, which will also greatly affect the development speed of defi. In addition, the roller coaster like ups and downs of defi projects (sushi, yam, yfii, etc.) also make people wary of its security. How to continuously accumulate user trust is also the focus of attention in the future.
blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block
blockchain is unified in the whole network, so it is logically centralized. From the perspective of architecture, blockchain is based on peer-to-peer network, so it is decentralized. From the perspective of governance, blockchain makes it difficult for a few people to control the whole system through consensus algorithm, so it is decentralized.
from cable TV companies to retail enterprises, all walks of life are trying their best to keep their most precious property: monopoly. The traditional view is: "if you control the entrance and channel, then consumers have little choice."
however, we see that companies like Netflix and Amazon break the old pattern and provide more choices for our lives. Similarly, in the field of digital currency and finance, some of the largest financial institutions are facing serious challenges
it is expected that decentralized business and demand will rise in 2019, which will provide more opportunities for successful blockchain companies. At the same time, but this opportunity also means risk. If, as in 2018, the founders or entrepreneurs of blockchain companies make too many promises, and the projects are suspected of exaggeration, they may lose their reputation and first mover advantage< For decades, the world's largest financial institutions have controlled most of the financial systems of the global economy
however, blockchain companies have begun to gain fair competition opportunities through access to banking services and real-time payment. In 2019, the blockchain instry will enter the field of securities, loans and other derivative financial procts in addition to financial payment. Companies like securitize *, Dharma, dydx, compound finance and the ocean are committed to building decentralized finance
in the past few years, mobile application companies such as rap, gojek and paytm have been expanding their business, with payment, investment, remittance, loan and insurance procts emerging. As many Asian economies move from cash to the digital economy, they are rapidly attracting users of new banks
Asian regulators have provided clearer guidelines for blockchain and digital currency projects because they believe that blockchain is a catalyst for economic growth and may become a sunrise instry in the future
in addition, more than 80% of digital currency trading volume comes from Asia, so digital currency investors are eager to establish reliable infrastructure. If Grab, Gojek and Paytm can benefit from digital money investors, they will begin to support the block chain more, providing awesome experience for payment, loans and other derivatives.
back to the original heart
in the past few years, the digital currency instry has deviated from its original financial vision, which is well illustrated in Nakamoto's bitcoin white paper. Just like the prosperity and depression of the Internet, almost all imaginable real cases, such as the logistics chain of tracking the freshness of flowers, are attracting people's attention with the hot word of blockchain
however, just like the early Internet, real landing cases must match the development stage of technology
Netflix, for example, could not successfully stream TV programs in 2000, when less than 1% of people used broadband. In the past few years, it has become more and more obvious that payment is a real case of massive application of blockchain
in 2019, blockchain companies will develop rapidly in decentralized financial applications (such as loans and insurance procts) based on the smart contract platform
I always find that the best application landing occurs in specific market segments. As long as blockchain companies can focus on procts that solve specific problems, we will see more competitive and innovative blockchain companies
and that's a good thing for the instry as a whole.
and enter the column
almost every supporter of encryption start-ups has a trend, that is, to use the decentralized value of blockchain technology to sell their business fundamentals
in this paper, we will explain the differences between decentralized financial agreement business and traditional business:
we will mainly discuss two aspects:
1) what is the real meaning of defi
2) what are the types and main differences of defi platforms< Users of traditional financial systems often want to build a system that is easier to access, more transparent, lower transaction costs and less dependent on intermediaries. To build such a more equitable financial system, banks, loans and derivatives must undergo fundamental changes. In addition, a decentralized ecosystem, such as defi, is needed. It promotes P2P lending, eliminates centralized control, and provides users with financial freedom
recently, in the field of cryptocurrency, there are many discussions about defi. It provides financial services to the world: loans, derivatives and other procts. Moreover, the role of traditional financial intermediaries has weakened, or even failed to play a role. Proponents of a decentralized financial system see defi as a good alternative to traditional lending. Some have called it the future of borrowing
defi is built on public blockchains such as bitcoin network and Ethereum. It has become one of the "core drivers" on the Ethereum network. By using unlicensed distributed networks, the defi platform converts financial procts into untrusted protocols that can be accessed by anyone anywhere in the world. People who don't have an account in the bank can also use the defi solution to loan and borrow assets, as well as to trade with financial instruments
open source platforms provide users with great benefits, including transparency, cheap cross-border transactions, no credit checks and less censorship. Anyone can carry out financial activities because there is no geographical restriction<
the degree of decentralization of defi
in recent months, the introction of defi solutions has proliferated. They have different models and their degree of decentralization is also different. Compared with other models, some defi models have poor dispersion. This is because only a few of their components are decentralized, while the rest are still centrally controlled by the company
the establishment of agreement, non trust, price supply, determination of interest rate, provision of liquidity of margin call and start-up of margin call are the key components of defi agreement. They determine the degree of decentralization
if there are a large number of decentralized components, then the defi protocol is more decentralized than other models. Such a protocol will give users complete control over their digital assets and get rid of centralized control. So far, there is no single defi protocol that disperses all components
each defi protocol is assigned a category according to the number of distributed components:
centralized finance (cefi)
defi solutions are usually unmanaged, which means that users can control their funds and be responsible for their security. Instead, cefi is hosted. The central system is responsible for keeping the assets of users and ensuring the safety of users' funds
when it comes to loans or loans, users can't control any aspect of funds. The interest rate is determined by the central government, and the liquidity of margin call is provided by the central system or authorities. Cefi procts use centralized price supply, and it is also permitted to issue margin call. Thank you very much for your patience. If you have any help, please accept it. I wish you a happy life! thank you!
With the expansion of the imagination boundary of the combination of blockchain technology and finance, the emergence of decentralized Finance (referred to as "defi") may bring some enlightenment. According to the latest data of the graph, a blockchain data index company, the number of defi monthly queries exceeded 1 billion in June. In the previous few months, the daily query volume of the graph hosting service was 20 million to 30 million, but in June, the daily query volume reached 40 million to 60 million
according to the report of dapppreview, the information and analysis platform of dapps based on blockchain, in the second quarter of 2020, the total transaction volume of Ethereum profi increased by 403% compared with the same period last year, and the market value of several Ethereum profi projects more than doubled in the second quarter. Under the frenzied pursuit of capital, it needs cold thinking to treat defi
defi
defi is still in its infancy, facing three major challenges:
first of all, code loopholes. Programmable finance represents the power of science and technology, but the loopholes after code stacking are always difficult to avoid
the second is the systemic risk. Whether it is traditional finance or programmable finance, we must consider the systemic risk, such as whether the defi ecosystem can carry it in the face of extreme market fluctuations
the third is the asset on the chain. The complexity and uncertainty of the asset on the chain is a great challenge for the whole defi instry, which needs to be tried by the pioneers
the defi application faces the risk of hacker attack. According to media reports, only from February to march in 2020, there were six security incidents in the field of defi, with a loss of more than $1.5 million

Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system< br />
secondly, the noise of bitcoin miner is very loud, with 90 decibels. A single miner can kill a family. If you play at home, unless you do sound insulation treatment
thirdly, the use of bitcoin mining machine needs to connect the ore pool to set up, etc., and it must have some professional operation knowledge, which is difficult for ordinary people to learn
Fourth, the running status of bitcoin miner needs to be monitored and monitored for 24 hours
fifthly, bitcoin miner will generate a lot of heat in the process of operation, so it is not cost-effective to use air conditioning at home
sixth, cluster mining, single miner output will be higher!
