Biyuan Chain released a white paper on MOV stable financial system, which can truly realize multi-asset mortgage

On January 15, Biyuanchain officially released the "MOV Stable Financial System White Paper 1.0".

This article proposes a stable coin financial system based on the MOV cross-chain ecology. From the perspective of basic economic principles and the construction of MOV infrastructure, a multi-collateralized collateral (BTC, ETH, USDT, and BTM) framework is developed, and a comprehensive stability mechanism and The clearing system introduces the concept of risk bonds, and based on the traditional financial field risk control models and theories, comprehensively builds a new vision of modern financial and multilateral trade on the chain.

It is reported that the four types of digital assets have different liquidity risks and market risks, and the degree of correlation risk will not be too high. Users can choose the type of collateral independently. The four types of digital assets are independently mortgaged and the risks are isolated. The discount rate is calculated separately.

Thinking of dYdX mortgage assets plunging 50%

During the period when the price of Ethereum (ETH) dropped to $ 120, the total locked assets of DeFi application dYdX plunged from a high of $ 30 million to $ 15 million. What are the reasons for this? In addition to the currency price factor, there are more reasons for too many people trying to liquidate, and dYdX's front-end server has collapsed under pressure. As a result, many traders were liquidated, so participants lost some confidence in the platform.

DYdX, which is in a "big distress", is currently in the recovery phase, but it does show that reliability incidents can cause irreparable damage to the reputation of the product / agreement. Compared with more traditional industries such as medicine / automotive, when we are considering making software, reliability is not our focus because of easy changes, and this matter is a good reminder to all DeFi teams that you The reliability of the front end is as important as the reliability of your contract, especially when the number of third-party interfaces of the protocol is limited. Moreover, if liquidity is a moat, its huge losses can really affect both sides of the currency market's balance. However, taking a step back and saying that one thing really worries me, when there are many liquidators competing for liquidation to demand returns, this competition will cause the price of gas to soar. If anyone can't keep up, the end result is that they can't close their positions.

CDPSaver encountered this situation in the last big price drop, but as the DeFi ecosystem grows, I expect this will become a bigger problem. The agreement can temporarily alleviate this situation by increasing collateral demand, although we must start moving DeFi to layer 2 and use the main chain as the settlement layer.

How the secret whale "liquidator" helps DeFi run smoothly

The liquidators are an under-appreciated role in the DeFi field. They work behind the scenes like miners and validators to keep the entire system up and running, and thus get rich returns. However, unlike miners and validators, clearing institutions don't actually require up-front capital investment, which creates an ecosystem of professionals who may operate anywhere in the world, be completely anonymous, and maintain the market by paying compensation Solvency.

to sum up

Through the data we can clearly see that the current Ethereum DeFi ecosystem is in a stage of rapid growth, and more and more public chains have aimed at this direction, but it seems that it is not wise to “hard and rigid” with Ethereum directly. The path of choice, mortgage ETH has almost become an inevitable choice.

From this perspective, the original chain selection idea is very reasonable. It chooses to realize the separate mortgage of four assets: BTC, ETH, USDT, and BTM through cross-chain. However, like most DeFi competitors, it lacks infrastructure. It is the most important problem to be solved in the current competition of the DeFi chain. In this regard, the Ethereum's DeFi ecosystem has been far ahead. In addition, the 50% drop in dYdX mortgage assets also gives us a good reminder that DeFi can easily reach the bottleneck in layer 1. It seems that layer 2 will be more suitable, but this will inevitably come at the expense of some attributes.

The era of DeFi's great sailing is slowly beginning. In 2020, it is worth looking forward to!
