Similarities and differences between PolarFox and The Graph

With the explosion of DeFi and NFT, the data of the blockchain is becoming more and more abundant, and the amount of data is very large. On the one hand, various applications or middleware need to quickly obtain public chain data, on the other hand, public chain data explodes, and a data middle layer is needed as a connector between the two. Like Chainlink, The Graph is also the middle layer of the blockchain. The demand for the middle layer is increasing and it is increasingly becoming an important infrastructure. Currently The Graph acts as a data connector between the public chain and applications on the Ethereum blockchain, providing indexing and query services for data on the chain for various applications. Nowadays, with the growth of the ecological scale of other chains such as BSC, dApps on BSC also have a large number of data query needs. PolarFox is currently providing data indexing and query services similar to The Graph for the BSC chain. However, PolarFox is currently starting in a centralized manner in the early stage, first to meet the urgent needs of data query for various applications, and then gradually move to The evolution of the centralized data middle layer. The index service provider in the Internet era is a search-zce engine company such as Google and Baidu, but what kind of project will the index service provider in the blockchain era be? Above we mentioned the rise of the data middle layer demand, so specifically, how to understand the data middle layer? Especially the data middle layer on the blockchain. For ordinary users, the word index is not easy to understand. In fact, we often encounter such things in reality. For example, when we go to the library to borrow books, how can we quickly find the books we need in a huge venue? If every time we borrow a book, we need to start looking for it from the first shelf, then everyone will collapse. An index is needed here. By categorizing books, numbering them, etc., we can quickly find the book we are looking for. Catheon Gaming and Polygon Announced as Preferred Blockchain Gaming Partners: On August 18th, Catheon Gaming (Catheon), a blockchain gaming entertainment platform, and Polygon Studios, a layer-2 expansion solution, announced to be the preferred blockchain gaming partnership . The partnership Catheon enables developers to build scalable user-friendly dApps with low transaction fees and guaranteed security.

Like search-zce engines, in order to allow users to find content-zce as soon as possible, the index of the database is needed. With an index, you don't need to scan the entire database table, you only need to provide relevant data, thereby improving query speed. Therefore, the goal of indexing is to find the target content-zce as soon as possible. The key word here is speed. There are also such problems in searching data in the blockchain. Blockchain data is now very large, and the demand for search-zce queries is increasing. This is a bit like the Internet period. In the early days of the Internet, the content-zce was not rich enough, and the demand for search-zce was not great. And when it develops to a certain period, with the great enrichment of websites, search-zce engines such as Yahoo, Google, Baidu and so on follow. Similarly, with the great enrichment of blockchain data, The Graph and PolarFox also follow. This is an important track in the blockchain era. In order to solve the problem of inefficient search-zce in the blockchain, some blockchain servers, such as blockchain browsers, will build their own servers to read all the data on the chain, and store these data in their own in the database. These are equivalent to indexing the original blockchain data, converting these data into a queryable format, and extracting data from the blockchain can help achieve faster queries. Polkadot Weekly: The Polkadot 65 referendum has been voted and implemented, and will be upgraded to runtime v9220: Golden Finance News, according to the latest Polkadot Weekly, the main events of this week are as follows: - Parity engineer Kian updated the May Polkadot Staking Monthly Report .

The cost is also high if each company builds its own data extraction service. Immunefi: White hat hackers discovered PoS system vulnerabilities in Polygon smart contracts: On February 21st, Immunefi released a vulnerability report on the Polygon consensus mechanism today. According to the report, on January 15, white hat Niv Yehezkel discovered a vulnerability in Polygon's proof-of-stake (PoS) system in smart contracts on Ethereum, which would allow an attacker to reduce the total stake, thereby allowing consensus to be bypassed, This could cause the attacker to lose all funds from the deposit manager, make unlimited withdrawals, DoS, etc. The vulnerability has a severity rating of $75,000 due to the complexity of its exploitation. For an attacker to exploit this vulnerability, certain market conditions must be met. For example, validator points must be open and have high capital requirements. The amount paid directly to miners to stay in the validator position using flashbots is also high. In addition, the checkpoint time of the Polygon network occurs every 30-45 minutes, and the attacker needs to maintain the verifier position for a long time, thereby increasing the attack cost due to the time requirement. [2022/2/21 10:06:16] This is why decentralized indexing protocols like The Graph and PolarFox have room to survive. A fully decentralized data indexing protocol can become an important building block in the encryption field and web3. However, as far as the evolution path is concerned, there are big differences between PolarFox and The Graph. Above we mentioned the importance of the data middle layer to the encryption field, especially the subsequent importance to the construction of the web3 network. So, what is the difference between PolarFox and The Graph, which also provide data middle layer services for the encryption field. Ethereum expansion solution Polygon integrates Mina protocol: Jinse Finance reported that Ethereum expansion solution Polygon announced its integration with the lightweight smart contract platform Mina Protocol. Compared to Ethereum's 300 GB blockchain, the Mina protocol is only a few kilobytes. The partnership means developers can now build applications on Polygon using Mina’s recursive zk-SNARK application, Snapp. [2021/9/10 23:13:51] Differences in entry positions and methods First of all, in essence, the long-term goal of both is to become a decentralized data index protocol and an important building block of web3. However, from the start point of view, there is a big difference between the two. Currently The Graph mainly serves the Ethereum network, while PolarFox mainly focuses on serving the BSC ecosystem. At the beginning, both had service hosting. Currently, in order to improve efficiency, PolarFox mainly focused on centralized hosting services in the early days, trying to provide specific fast query services for various applications on the BSC chain. The Graph also had hosting services in the early days of its launch, but recently, The Graph has gradually evolved towards decentralization. From this perspective, the evolution of The Graph is relatively fast. Also because of this model of The Graph, it is currently unable to quickly provide services on BSC, because its decentralized model takes longer to advance. This gave PolarFox the opportunity to cut in. PolarFox entered from the weak side of The Graph, breaking through first where The Graph was underserved. Data: The current total lock-up volume on Polygon is 5.46 billion US dollars: Jinse Finance reported that according to DeBank data, the current total lock-up volume on Polygon is 5.46 billion US dollars, and the net lock-up volume is 4.37 billion US dollars. The top five locked assets are Aave ($2.1 billion), QuickSwap ($1.1 billion), SushiSwap ($482 million), Curve ($477 million), and BalancerV2 ($197 million). [2021/9/1 22:50:31] In order to serve the growing data query demand on BSC faster, PolarFox adopted the method of cooperating with project parties (such as Pancake) to rapidly promote its business in the early stage. Of course, in the long run, this is an expedient measure. Differences in early frameworks The Graph protocol uses the query language GraphQL to query the blockchain, and people query according to the fields or search-zce criteria they are interested in. The data that can be queried is organized according to the subgraph (subgraph), and multiple subgraphs can be used. For example, you can search-zce Uniswap's daily transaction volume, transaction times and other data. In The Graph, there are the roles of indexer (indexer), queryer (query demander), curator (Curator), delegator, supervisor (Fishermen) and arbitrator (Arbitrator). Indexers are also node operators. Indexers need to become nodes by staking GRT tokens. The main function of the node is to index related subgraphs and serve various queryers, which can be other web servers or middleware, or end users. These queryers need to pay a fee to obtain the different subgraph data provided by the indexer. Therefore, The Graph is a decentralized index market with multiple indexers, so it is also a competitive market. With a competitive market, it will also lead to an equilibrium in the price of inquiry services. In addition to the supply and demand sides of indexers and queryers, there is also the role of Curator. The purpose of curators is to discover indexable subgraphs, and they use the token GRT to point to these valuable subgraphs. If these subgraphs prove to be popular, curators are also rewarded accordingly. A curator can be any user, such as an end user who finds the value of subgraphs worth indexing, or a developer who wants their subgraphs to be indexed by Indexer. Through the deposit of tokens, subgraphs with more pledged tokens are more likely to attract the attention of indexers. Curators stake GRT onto a certain bonding curve, which signals from a specific subgraph. If you pledge a subgraph earlier, based on its pledge amount, the higher the query income you can get. The delegator does not need to run The Graph node, entrusts its tokens to the indexer, and can obtain part of the indexer's income. Supervisors (Fishermen) are responsible for discovering indexers that provide wrong indexing services, and arbitrators are responsible for arbitrating disputed services. From the above structure, in order to achieve a decentralized index, The Graph introduces six roles. This has a certain threshold for understanding its project at the beginning. In addition, because more roles are involved, it will take longer to start early, and some sacrifices will be made in efficiency. For example, whether the curator’s guidance to valuable subgraphs is efficient, what is the quality of subgraphs and indexing services, and whether they can meet the queryer’s fast query needs, etc. The current roles on PolarFox mainly include query demanders (mainly project parties), index service providers, and token holders. This is a simplification. The provider of indexing services was initially dominated by PolarFox, while the query demand side was project parties on various public chains such as BSC or Ethereum, such as DEX and lending protocol applications, which have extremely large demand for indexing and query services. Token holders are equivalent to financial supporters supporting PolarFox. The advantage of this entry mode is that it can more efficiently serve the query needs of current dApps in a centralized way, such as pancakeswap on BSC, etc., and enter the index and query service market faster and with higher quality. Of course, it also has shortcomings. It has made certain sacrifices in terms of decentralization, and its openness is not as good as The Graph. If there is no subsequent iteration, it will not be able to become the data middle layer of web3. Differences in the Token Economy In terms of the design of the token economy, it is currently serving the current early architecture of the two. The token of The Graph is GRT, which is a utility token and has the following main uses: 1. To become an indexer, you need to pledge GRT; 2. Curators use GRT to send signals worthy of indexing subgraphs; 3. Delegators entrust indexing 4. Queryers (consumers) pay GRT fees for their queries. In order to build its decentralized index market, GRT has an annual inflation of 3% in addition to the initial issuance of 10 billion. Pay index rewards. In addition, GRT's token value capture is mainly its token destruction, and the scale of destruction is 1% of the total protocol query fee. The total amount of PolarFox tokens POLR is 1 billion, and POLR is also a utility token, which is used to pay for inquiry services. 1. The project party (query demander) needs to pledge POLR tokens, and then by consuming the pledged tokens, they can obtain data indexing and query services provided by PolarFox. 2. Participate in liquidity mining, and ordinary users can obtain corresponding token income by staking POLR.
