According to data provided by dapptotal, the total value of the DeFi ecosystem's overall lock-in (USD) in the past week was approximately $ 845.3 million, a decrease of 0.78% year-on-year (Note: EOS REX was added to this week's data). InstaDApp, which ranked 7th in the total value of the original lockdown, increased by about 19.08% in a week, surpassing Uniswap, and currently ranks 6th temporarily.


Data from (

Since MakerDAO launched the multi-mortgage Dai in November, the ratio of single-mortgage Sai and multi-mortgage Dai across the entire network has remained at about 1: 1, and ETH still accounts for most of the mortgage assets. At present, BAT's mortgage capital is about 383. Million USD, accounting for approximately 2.01%, and ETH mortgage funds are approximately USD 186.7 million, accounting for approximately 97.99%.

Du Xiaoman Releases DeFi White Paper, R Value and Token Co-Incentive

This week, Du Xiaoman Blockchain Lab and Peking University Guanghua released a " Du Xiaoman Distributed Financial Technology White Paper (2019) ". In this white paper, Du Xiaoman Finance proposed a standard architecture solution for DeFi. DOTA (see Babbitt's report for details), according to the design, the framework will have a distributed financial identity (e-DID) implementation, and will adopt a distributed ledger model based on DAG. In addition, Dota-Core also introduced the R value ( (Representing the user's credit score) A collaborative incentive scheme combined with Token.

In addition, according to the description in the white paper, the tokens in the DOTA network are only described as gas, and the tokens of each universe (conceptually corresponding to the domain of the DOTA architecture) are independent and non-interoperable. They are mainly used as transaction fees and as Provide rewards for high R value users.

The framework is mainly targeted at generalized DeFi applications such as digital asset confirmation, digital asset management, data value transfer, and financial business distribution.

Of course, as stated in the white paper, synergy with regulation is the weakest initiative among the challenges facing DeFi. This is a long process involving constant communication, collaboration, promotion, and improvement. However, DeFi needs considerable development and compliance with regulatory requirements is an indispensable condition.

Apple and Google block decentralized browser applications, whose cheese has DeFi moved?

Compared with Baidu's embrace, the two foreign giants Apple and Google have taken very different measures. Earlier this week, the MetaMask Android client was taken down by the Google App Store. On the weekend, Coinbase Wallet announced They said that in order to comply with the App Store policy, they will soon remove DApp browser features.

In a Reddit article , Coinbase CEO Brian Armstrong stated:

"It's really unfortunate that Apple seems to be clearing Dapps from the App Store.

If Apple customers want to use Dapp, we may need to somehow let Apple know about the request. This is an important innovation in the financial field. Many developers and early adopters have bundled hundreds of millions of dollars in these financial applications. If this app store policy continues, they will not be able to use these on Apple mobile devices. Innovative applications. " It is reported that Web 3 browser applications such as MetaMask are important entrances to the Ethereum DeFi ecosystem. It is not clear whether the two giant companies will take further action.

DeFi 2019 and 2020

We often say that 2019 is the year of DeFi, but it is certain that compared with the traditional financial industry and even with decentralized cryptocurrency platforms, the vast majority of DeFi indicators are very small in absolute value. Every day Only a few hundred to thousands of people are using DeFi. Although the total value of the lock is soaring, it has not exceeded $ 1 billion so far. However, considering that the system has only been activated for two years, what has been achieved so far Progress is still significant.

According to the annual DeFi summary article published by The Defiant, in 2019, borrowing is still the main application of DeFi, and the total amount of related loans has more than doubled, and MakerDAO has taken the lead in this field, but new participants It has taken some market share, which highlights a maturing market. The intensified competition has also benefited users. The user interface of various DeFi applications has been improved, and to a certain extent, the cost of borrowing has been reduced: Dai has been reduced from 16% (annualized) in mid-19 to December About 4% (annualization).

After lending, derivatives grew to second place, with Synthetix leading the way in this category. With the exception of borrowing and derivatives, developers continue to explore the creation of new financial systems, and the lock-in value and number of projects in all categories are increasing. Examples are social currencies, streaming payments, tokenized savings accounts, and more.

The decentralized exchange (DEX) has the least number of new users, but the improvement in user experience has led to a surge in the number of users of the two DEX applications, Uniswap and Kyber Network. According to data provided by Dune Analytics, the DEX transaction volume in 2019 is approximately $ 2.3 billion, which is still insignificant compared to the transaction volume of centralized exchanges. The development of zero-knowledge extension technology and the recent updates of the DEX platform are expected to capture more users and use in the future.

These tools and platforms can be built on top of each other and use each other's infrastructure. This is like a "Lego Money" game, which helps promote growth, collaboration and innovation, but may also increase systemic risk .

The next milestone in the DeFi industry requires breakthroughs in the following four areas:

  1. A smoother exchange channel between cryptocurrencies and fiat currencies;
  2. Reduce pledge rate;
  3. Decentralized identity
  4. Clear supervision;

DeFi project progress in one week

  1. Chainlink and Luyin have reached a cooperation and will integrate multiple oracles in Luyin v3 zkRollup DEX protocol ;
  2. Augur, a decentralized oracle platform, will launch v2 in Q1 2020, and will use McDai ;
  3. DeFiZap announces integration of Ethereum domain name service ENS ;

to sum up

This week's DeFi ecological data has not changed much from last week, but it has ushered in several heavier news. One is Baidu's Du Xiaoman released a DeFi white paper, and the other is Google and Apple. Giant companies are deporting decentralized browser applications. Despite their different approaches, they all prove that DeFi applications have received the attention of the giants.

In addition, the development of the DeFi industry in 2020 can be described as promising, and its biggest challenge may be regulation.
