Ethereum defi team

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

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

Nash 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 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

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

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. 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 />

The total number of atomic coins issued was 100 billion, and the total number of atomic coins was 1; 10 mapping

token is a tool to measure the transmission and transformation of value. As the parties participating in the construction of the system, token is the qualification basis for the distribution of rights and interests. Atomic chain will issue endogenous currency, which we call ATOS. In the initial stage of the system, it will be released based on erc20. In the medium-term stage, the 1:1 smooth migration to the main network of the atomic chain. Erc20 is a standard protocol on Ethereum network. It uses the protocol interface to create a token, which is used as the basis of warrant and qualification of each role. ATOS is the basic circulation value of the whole ecosystem. Through ATOS, users can realize transaction, value transfer, enjoy value preservation and increase, and vote. Atos is also the basic reward condition for each role to participate in. Through the reward, the enthusiasm among the roles can be stimulated, and the virtuous cycle of the ecosystem can be promoted. In order to fight against inflation and maintain and increase the value of contracts, we will issue a fixed number of ATOS. Through ecological operation, ATOS will maintain a certain minimum value. We use push in the ecosystem to push the ecological event report according to a certain period< ATOS is divided into circulation pool and lock pool. Under the condition of constant total amount, the total amount of market circulation and lock pool will maintain a certain proportion, so as to achieve the balance point within the pool

More and more people want to steal money by attacking smart contracts. They are taking advantage of the loopholes when smart contracts are combined

in 2020, the total amount of embezzlement or theft in the attack on defi has reached 36 million US dollars. But because dforce attackers returned the stolen $25 million, the actual amount was about $11 million

compared with the early days of Ethereum, the average loss value of each hacker attack has decreased significantly. Eight of the 10 attacks in 2020 are worth less than $1 million

defi

in the early days of Ethereum, most attacks were based on finding indivial vulnerabilities, which enabled attackers to freeze or exhaust smart contracts. This was the case with the notorious Dao hacking incident in 2016, in which $160 million eth was stolen and Ethereum finally forked out. Similarly, the multi signature attack of parity in 2017 caused hackers to steal $30 million, and $150 million in parity's wallet was frozen, all of which were the consequences of such vulnerabilities

the loopholes of such smart contracts are still exploited from time to time. Recently, an attacker succeeded in stealing all Veth from token contracts, making a profit of $900000 just by exhausting the veth-eth uniswap pool. But this is a simple mistake caused by Veth, because there is a logical error in the way Veth modifies the erc20 token standard

generally speaking, the security has been improved, especially for the projects with high attention. Their security improvement is driven by the user's expectation of audit and the improvement of testing tools. Recently, the biggest security problem in defi is that dforce's $25 million digital assets have been stolen from the lending market. However, the funds were withdrawn because the attacker's IP address was found and shared with the Singapore police

I believe there is a fraud in issuing digital currency, but there is a fraud in mining. Unless you buy a "nonexistent" mining machine or computing power, the probability of being cheated is almost zero. Next, let me talk about UTC's past and present lives

moreover, as far as I know, the team behind UTC, as well as the financial and technical support are quite reliable. If it is really a scam, the institutions that invest in UTC will not make such a big battle to cheat people
