A layered analysis of specific tracks shows that obvious investment opportunities are more likely to exist at the level of infrastructure and hosting solutions. The NFT industry is still in its infancy, and a sound infrastructure can greatly improve development and user experience. The head effect of the project will also be more obvious. In 2019, the retention rate of most projects is low, with an average usage period of 3 months, and only 3.5% of the platforms have been used for more than 10 months. Only 12% of new assets flow among users (Liquidity rate).

# Comparison of decentralized options exchanges

There are now a total of 4 centralized exchanges that have launched option contracts, but they are all European options. The American options provided by the decentralized options exchanges Opyn and Hegic can bring higher exercise flexibility and have certain advantages. Moreover, users are required to 100% collateralize all positions. Although the threshold is higher, it relatively eliminates counterparty risk. The two options exchanges have their own advantages and disadvantages in terms of product, trading method security and other latitudes:

The advantages of Opyn are:

1. Provide more call and put option contracts for encrypted assets.

2. The option is initiated by the seller, and the oToken is minted to represent its contract, and can be freely traded on uniswap.

3. No security loopholes have been found for the time being, and it is relatively safer.

4. More trading volume and open interest.

5. The team and financing information are more transparent.

6. In terms of exercise fees, the algorithmic exchange rate of Uniswap liquidity is adopted, which is highly correlated with the real-time dynamics of the market.

1. The contract is initiated by the buyer and takes the entire Hegic pool liquidity pool as the counterparty. And let the liquidity provider share the premium and loss of all contracts, which greatly increases the capital efficiency and the risk of a single liquidity provider to increase liquidity.

Ren CEO Taiyang Zhang stated that in DeFi liquidity mining, users will not "directly" pay for mining tokens. Instead, users are providing assets to the protocol, which does not require an upfront cost, but an opportunity cost. Caution is required when interacting with DeFi protocols that allow the use of leverage.

* DeFi

Vitalik Buterin, the co-founder of Ethereum, issued multiple tweets in response to the DeFi boom, saying that in the long run, the interest rate of DeFi cannot be higher than the best interest rate of traditional finance by more than one percentage point. In fact, many of the most valuable parts of DeFi may be the most boring, which is simply giving anyone in the world a crypto dollar with an interest rate that matches the rate of inflation, and this is a huge boon for many people .

@IOSG VC:

The security breach was possible because Balancer allows non-standard ERC20 tokens. Specifically, the funds from two pools containing STA and STONK token were completely drained. These are deflationary tokens that lose balance with each trade. After running numerous trades in these tokens and lowering token balance in the pool, STA token became expensive relative to the other tokens which the attacker used to exchange STA for other assets in the pool.

Despite the attack had a limited scope, affecting about 0.36% of the total liquidity on Balancer pools, Balancer decided to reimburse all affected because they could have prevented the loss. Namely, Hex Capital warned Balancer about this bug (May 6th). Balancer emphasized that there will be no guarantee for potential future incidents and that users should assume the risks of smart contracts. Looking forward, Balancer plans to perform the third audit, this time with OpenZeppelin. The first two audits were performed by Trail of Bits and Consensys Diligence.

Balancer announced on June 29 that it will make full compensation to those who were attacked by flash loans, about $500,000. Then on June 30th the attack happened again

Ethereum Mutual Insurance Nexus Mutual announced the launch of a new Staking (pledge) system, platform users can stake on contracts they deem safe and receive corresponding rewards. The staking system allows the same NXM (Nexus Mutual's native token) deposit to be pledged on multiple contracts at the same time to maximize potential returns and improve the capital efficiency of the pledge. Up to 10 times the pledged NXM can be pledged on multiple contracts Quantity, and the relevant rewards and penalties in each smart contract system will be distributed proportionally.

As an insurance platform, Nexus Mutual adopts the insurance pool model, and the two most important mechanisms are claim assessment and risk assessment.

risk assessment

Nexus Mutual introduces the method of decentralized risk assessment (Decentralized risk assessment). Decentralized risk assessment actually allows some smart contract security audit experts (Smart Contract Auditors) to target specific risks, pledge tokens, and participate in risk assessment. Of course, they can also obtain token rewards from the system. They are in Nexus Mutual is called Risk Assessors (Risk Assessors)

* Layer1

For a smart contract that the risk assessor thinks is safe, he/she can pledge tokens, which also shows that the smart contract is safe. If the smart contract is insecure and stolen, their previously staked tokens are burned (as punishment).
