Ⅰ What is the development trend of NFT in 2021?

The rise of the NFT market began with the Crypt Kitties game in the second half of 2017. In 2020, the NFC market began to boom. Compared with distributed storage and DeFi, NFT belongs to a relatively small class. The unique charm of NFT is that it has joined many stars, artists and other groups and created many legendary stories, which cannot be ignored for a long time.

CryptoKitties

Take the most typical CryptoKitties in the NFT circle as an example. Each NFT pass can add many attributes. For example, you can record the cat's age, coat color, rarity, interests, age and other characteristics. Why do some CryptoKitties sell for hundreds of thousands? The proof of general versatility is based on ERC20, so the attributes of the asset cannot be recorded. NFT is based on ERC721 or ERC-998 or others. This is because the underlying architecture is different, and NFT certificates have features that allow attributes to be added.

For example, airplane tickets. A general certificate can only record one ticket. However, NFT can record information such as whether the plane ticket is by the window. For example, in a hotel, in addition to recording the place and hotel name, NFT can also record the floor, orientation, area, style, price, breakfast, etc. of each hotel room.

From a global market perspective, the demand in the game market is very large. The future development of NFT provides huge potential, but there is also a killer feature: defi. There is no doubt that 2020 is the year of decentralized finance. According to data from DoF Pulse, the DoF market has grown more than 20 times since January last year.

NFTs are developing rapidly and becoming increasingly popular, but compared to other cryptocurrency markets, NFTs are still relatively illiquid, which limits the value of NFTs. Now, many projects are optimistic about the combination of defi and NFT. I believe the combination of the two will enhance the value of both parties. NFT is still a very emerging field, but it now has a core functionality that allows NFT holders to put their tokens into WiFi applications. So someone who owns a rare crypto kitty or dispersed land can use their NFT as collateral to get a loan. This is nftfi, known as the "NFT mortgage market." The borrower agrees to have their NFT included in the smart contract. If the borrower fails to repay, the lock on the lender is released.

Ⅷ What is DeFi (decentralized finance) and what is the ecosystem behind it

3. Decentralized prediction platform

Prediction markets have long been a popular financial tool for hedging risks and speculating on global events. Decentralized prediction markets achieve the same functionality, but with cryptocurrencies and the inability to censor the market. Augur already offers everything from political and weather forecasts to dealing with real-world risks of financial or adverse events.

4. Exchanges and open markets

The role of exchanges is realized through decentralized exchanges (DEX). A DEX is a P2P market for assets on Ethereum between two parties, with no third party acting as an intermediary for transactions. Therefore, they differ from centralized exchanges like Coinbase & Co. in this regard. Some DEXs also use some highly innovative token exchange methods, such as atomic swaps and other non-storage ways of exchanging one asset for another with minimal settlement time and risk.

Other types of open markets focus on exchanging non-fungible tokens (NFTs), often called cryptocurrency collectibles. Platforms like OpenSea and Rarebits facilitate the search and purchase/sale of crypto assets, ranging from NFTs in games like Cryptokitties to virtual parcels in the game Decentraland. Some markets, such as District0X, are even said to allow users to create their own exchanges and vote on the governance process. Current examples of dexes offering cryptocurrency trading include Binance DEX and Ether Delta.

5. Stablecoins

Nowadays, there are many types of stablecoins. They differ in part in how they issue coins, how their reserves are checked, and the mechanisms by which prices are determined. Stablecoins are tokens issued by the blockchain that aim to maintain a stable value. This is usually achieved by pegging it to the US dollar, gold or other external assets. Roughly speaking, stablecoins can be divided into the following three categories:

Cryptocurrency pledged, legal currency pledged, non-pledged

Cryptocurrency pledged stablecoins include Maker’s Dai. However, stablecoins backed by fiat currencies are by far the most popular stablecoins on the market. The first was Tether, although there are now many alternatives. The models of these stablecoins are not that different from each other. For all of this, users must trust the provider. Some offer regular and voluntary audits to build the necessary trust through transparency.

Uncollateralized stablecoins are neither centralized nor backed by cryptocurrency assets. They are based on algorithms to maintain stable values. Simply put, the algorithm takes supply and demand as parameters and adjusts accordingly to always maintain a balance. Basis was a pioneer in the category but failed due to regulatory concerns. As a result, the project was abandoned.

The future of DeFi—what’s the potential?

Of course, the final question is how big is the potential of the entire DeFi movement? Basically it can be said that there are many things in the cryptocurrency field that are simplifiedexaggerated. Immeasurable potential is attributed to the vision, so the actual product has no chance of living up to the inflated expectations. What follows is severe disillusionment and boredom. However, compared to DeFi, it is different because there are already some finished products, such as MakerDao, and the market has accepted them well.

Despite this, we are still in the early stages of the entire DeFi movement. However, the potential behind it is huge. Even if only a small part of DeFi (such as Lending) succeeds in the future, this is more than enough. If the DeFi ecosystem is able to offer loans with better terms than most national banks and other lending institutions, it could lead to global adoption.

But this is also one of the biggest obstacles that we still need to overcome in the DeFi field. On the one hand, more education is needed so that the masses even know that this alternative exists. As before, only a very small percentage of people are worried about issues related to cryptocurrencies and blockchain technology. Especially there are even fewer people who deal with the DeFi sector and have not even heard of it. On the other hand, the user-friendliness of such products must be greatly improved, thus paving the necessary path for mass adoption of the product and global adoption.
