What are the sectors of decentralized finance
blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
blockchain is an important concept of bitcoin. In essence, it is 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, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
extended data
according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:
1. The blockchain with the whole network open and without user authorization mechanism is called public chain
2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain
3. All the nodes in the network are in the hands of one organization, which is called private chain
alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain
blockchain features
1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously
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
with the diversification of network service forms, the decentralized network model becomes more and more clear and possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together
decentralization is a phenomenon or structure, which can only appear or exist in a system with many nodes or in a group with many indivials-- Cloud financial services for you

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.
A. indivials with asset management needs do not need to trust any intermediaries, and the new trust is rebuilt on the machine and code
B. everyone has access, no one has central control
C. all protocols are open source, so anyone can cooperate on the protocols to build new financial procts and accelerate financial innovation under the network effect
defi is a relatively broad concept, including currency issuance, currency transaction, loan, asset transaction, investment and financing, etc
we regard the birth of BTC and other cryptocurrencies as the first stage of decentralized finance. However, the decentralization of currency issuance and storage only provides a point-to-point settlement solution, which is not enough to support the rich financial business. The rapid development of decentralized lending agreements in the past two years will have the opportunity to further open the financial system of the blockchain world and bring decentralized finance into the second stage<

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!
