Talking about DeFi | Decentralized Financial Services

DeFi refers to decentralized financial services. It does not require any large financial institutions or government organizations, and can achieve rich functions such as trading, lending, and insurance. If you are not familiar with DeFi services, you can think of DeFi as an automatic Vending machine, for those who want to use the vending machine, we only need to know what this service can do (you can buy snacks and drinks), what I need to input (full coins and banknotes), and how to choose the service I want ( Press the button that I want the product), and finally get the service I want (get the product), you will find that we can actually use the vending machine without really knowing the hardware and code of the vending machine.

All DeFi protocols are written in code. After verification, they are published on the blockchain. We know that the blockchain has the characteristics of immutability. No one has the right to change it and cause unexpected errors. All the code of this protocol can also be seen on the blockchain browser . Because of these public code, these decentralized financial services do not require the intervention of any centralized organization, and everyone can do so without trust. Use financial services.

Since the end of 2018, the DeFi world has only had tens of thousands of US dollars locked in assets. It has grown explosively so far. At present, almost all assets locked in the value of more than 200 B (200 billion) US dollars can be stably maintained. With the outbreak of the public chain, each chain needs its own DeFi services, and similar protocols may have completely different names on different chains. Facing such a large, complex and rapidly changing DeFi, it is always dizzying and overwhelming. It's even more unfriendly to people new to the cryptocurrency world.

This article is going to recommend a DeFi and NFT tracking tool "DefiLlama". By introducing how to use it, I hope that people who want to enter the DeFi world but don't know where to start, or want to know what projects are currently popular, can It’s easier to discover what you want to study. Just as the so-called bear market sharpens the knife, let’s study harder in order to find the next track opportunity.

DefiLlama

DefiLlama is committed to providing an easier-to-use decentralized finance and NFT data tracking service. This data is very open, transparent, accurate and fast. Their data source is the integration of some on-chain databases (such as Uniswap.info, CoinGecko, etc.) , this All in one integration service allows us to get all the information on different chains on one platform, which is really very convenient.

Its most powerful function is to help you count the data of each blockchain or each protocol, including the TVL (Total Value Locked, total locked volume) that many people value most, or the largest protocol in a certain field and its market share Wait, now we have started to provide NFT related data. This database can make it easier for us to grasp the market price of popular NFTs in various chains, as well as the related transaction volume of the NFT market, etc. If you don’t know what NFT is , you can refer to the article I wrote before: One article to understand what is NFT and its application .

If we can master these DeFi and NFT data for analysis, we may be able to avoid some dangers and even gain some opportunities, so I would like to recommend it to everyone here. If you have some experience, please share with me. Everyone It will be faster to communicate and grow with each other. In this article, DefiLlama will be divided into two parts: DeFi and NFT.

DefiLlama | DeFi part

1. Overview General direction data

On the homepage of DefiLlama, you will see Total TVL first. This data means that on different blockchains, all the cryptocurrencies locked by the agreement are converted into the market value of U.S. dollars at the moment. Taking this picture as an example, the author writes the current There are 231.33 billion US dollars worth of cryptocurrencies in the DeFi protocol in the blockchain world.

The TVL Rankings table below is the ranking calculated by a single DeFi protocol according to the current locked market value, and if the protocol has services on more than one blockchain, the total ranking of all chains of the protocol will be calculated, then we From this table, you can easily grasp which protocols are currently the strongest.

This table also provides switching between different blockchains. If you stay in All, it will be a chaos of all blockchain protocols, but if you have a commonly used blockchain, you can switch to the corresponding one through the options on the right side of TVL Rankings. The blockchain, so that the entire page can only see the TVL of the blockchain and the strongest agreement on the blockchain.

In addition to knowing the amount of TVL, you can also see the TVL changes of 1 day, 7 days and a month, so that we can more quickly grasp whether this protocol is still growing. After all, most DeFi protocols need it. The liquidity of funds is prone to many dangers once funds start to withdraw frantically. It is easier to avoid dangers by mastering this indicator.

In addition, there is a search function at the top of the home page. If you just want to immediately confirm the recent performance of a protocol you already know, you can directly query it here, regardless of the full name of the protocol or the code issued by the protocol. Coins can be clearly queried in theory.

2. Various on-chain data

The "Overview" part of the home page has been introduced earlier, and other functions can be found on the left menu. There are a few important things here that I think can be studied, namely "Chains", "Oracles" and "Languages".

The first is "Chains", where you can know the TVL, TVL changes and the number of agreements of each blockchain, and even more detailed, you can also list the L2 of the chain and how many agreements, if you want to know the The protocol ranking in the blockchain can also directly display the protocol data of the chain in a new window by clicking Name.

"Oracles" refers to oracles. Oracles are very important DeFi services. In the decentralized world, oracles are used as a trusted third-party protocol. We expect to input a question and it can Outputting the answer to this question to achieve the interface between the real world and the blockchain world is a bit abstract. If there is a chance in the future, I will write another article about oracles.

The last one is "Languages", which should be used to calculate the total number of TVLs of DeFi protocols developed by this programming language. If you start to study DeFi, you must know that all DeFi services you see are intelligence developed by programming. Contract composition, then understanding this indicator will help us understand the current mainstream programming languages in this industry. Perhaps because of studying the current popular smart contract development languages, we can find a good opportunity to change jobs! ?

3. Other interesting data

There are still many functions that have not been introduced. I will share some data that I think are interesting and may be worth paying attention to. Everyone can evaluate how to use it by themselves.

With the continuous evolution of decentralized finance, in addition to moving the set of traditional financial things to play, some financial services that can only be played in the blockchain world have gradually developed, and different protocols have sprung up like mushrooms after a rain. It’s dazzling and very difficult to grasp. “Categories” are the so-called types of protocols. The ranking after TVL is calculated by each type, which allows us to see more clearly that most of the funds are now developing in those DeFi fields. Great opportunity to serve. For example, the NFT Lending service generated by the popularity of NFT is very new. Although I have not studied how it will work, it will be very interesting.

"Airdrops" will sort out those protocols that have not yet issued tokens and have high TVL. Maybe use it now. If it does issue tokens in the future, you will have the opportunity to receive Uniswap, Ethereum Name Service, etc. Free airdrops of top tokens, take the opportunity to earn a lot of votes!

DefiLlama | NFT part

As many celebrities and companies started to issue NFTs, more and more outsiders who had never used blockchain-related applications before were hit and began to invest in this market, so that the NFT market gradually expanded, driving a With the wave of cryptocurrency frenzy, DefiLlama has started to develop NFT-related data tracking. At present, there are not many functions. In fact, I can’t think of what kind of tracking other than these functions that have been opened…

First of all, in "Overview", you can see the total transaction amount of blockchain for NFT and the current number of holders and floor prices of each NFT project. In "Chains", you can see the total transaction amount on each blockchain, but to be honest Seeing these rankings does not seem to help much. Since NFT is a relatively illiquid market, after reading these data, you can only know that NFT is developing more vigorously on those blockchains, and what well-known NFT projects are currently there. .

"Marketplaces" is the total transaction amount of each secondary market, but according to the current data, Opensea's transaction amount still accounts for more than 95%, that is to say, if we add up the transaction amount of all NFT secondary markets except Opensea If it is multiplied by 20 times, it is still no better than an Opensea. I look forward to some platforms that can compete with Opensea in the future. Such an industry will be relatively healthy.

summary

After roughly browsing these function introductions, it can be seen that DefiLlama is very well organized in terms of data integration, and it will be updated regularly to add new functions. If you find any new continents while using, please come back to share with me and discuss with each other Strive for each other, and sometimes you will see more different points of view!
