技术解析API3：预言机赛道的又一批黑马？

When it comes to the prophetic machine track, everyone will take it for granted, but with the rise of the new performance public chain, various new modules and lightweight projects have emerged, and the prophetic machine track has also begun to roll up. Recently, there has been a killing voice in the market. What will it really do? Next, I will talk about my understanding based on the perspective of popular science business competition. Usually, such prophetic machine services are predicted by the data source exchange, data acquisition node service provider and data processing center. The destination and other components are equivalent to building a bridge from data sources to blockchain applications. The Oracle node multi-pipeline collects data from different channels simultaneously, and the Oracle network coordinates the processing, verification and aggregation of these data to reduce the error, and finally feeds the price to the terminal intelligent contract demander. At present, there are two key points in the Oracle workflow. The more data collection nodes, the richer, more accurate and decentralized the collected data sources are, but the nodes do the work of ascetics and can only collect data mechanically for excavation. The more intelligent contract parties are connected to the network of the mine Oracle, the more centralized the price processing of the Oracle will be. The greater the intervention in data, the higher the trust cost of the end customers. In essence, the Oracle network acts as a third-party intermediary platform, so the role and space of service nodes will be relatively limited, and the more authoritative the Oracle platform itself will be, the more centralized it will be. This is almost an irreconcilable contradiction. The first-party Oracle platform is actually removed. The intermediate link of preprocessing directly connects the data source and the project party to the node, realizing the role of being the master, upgrading the operation and refined development based on the collected data, enhancing the service ability of the node, collecting more customized data sources and serving the special needs, and for the terminal project party, directly cooperating with the node at a lower cost to customize and develop the special data needs more flexibly, thus providing necessary predictions for its innovative application products. It is not difficult to see that it is a more decentralized and flexible long-tail market of Oracle that is cut into. It is to activate the comprehensive operation and maintenance service ability of service nodes as the starting point to build a bridge between the demand side and the supply side of Oracle in a lighter and modular way. How to do this mainly includes two core components, which provide a set of foundation for node service providers from building Oracle nodes to connecting project parties, so that nodes can be deployed in a lower cost and lighter way. The simplified configuration and management process of Oracle service makes it easy for providers who are not familiar with blockchain technology to become Oracle nodes. The operator is equivalent to a decentralized organization node, which uses signatures to continuously collect and update data from data sources, while the smart contract of the data demander can safely and transparently call data and pay on demand. The whole management and operation is provided by decentralized organizations through a reward and punishment mechanism. In general, it tries to use lightweight basic services. And the mature customer group with super fans, the stable price pretreatment method and the unshakable existence of business strategy thinking are the same as the market that keeps robbing Ethereum. After all, it is impossible to serve all smart contract customers. After all, there are always some lightweight customers who pay more attention to cost and cost performance. After all, there are always customers who need more timely and customized data source services. After all, there are always nodes who want to explore more comprehensive and rich industries. Service mode and so on is not so much a killer as a powerful supplement to divide the market together. As for whether the end customers prefer stable and mature services or prefer low-cost and flexible service options, it depends entirely on the market. In my opinion, it is very difficult to threaten in the short term, but in the long run, the choice of blockchain application market that is becoming more and more modular is also very interesting and right. Recently, magic change has built a public chain. How to understand the application scenarios of this public chain? Many nodes have data. Permission in the scenario, if the smart contract triggers a certain price point, the liquidator can choose to buy the assets pledged by the user so as to obtain arbitrage value after the price is stable. Under normal circumstances, the liquidator is actually a node service provider. After all, they have the right to update the price of the smart contract agreement. Before the governance mode comes out, this liquidation behavior may be chaotic. Nodes may update the data first in order to obtain the liquidation right. Multiple nodes may aggravate the fluctuation of the market price in order to seize the liquidation right. According to the fact that the supplier has become an arbitrageur that may disturb the normal market order, it is obviously stale, but there is actually no way to curb the direct connection of nodes to smart contracts. The project side is to reduce platform intervention and enhance market-oriented operation. No third party can effectively intervene in the arbitrage and chaos in the market, but it can only be restrained through the governance mechanism, which is equivalent to a set of rules. The governance mechanism stipulates that when the user's position is close to liquidation, he can participate in the online auction, and the highest bidder gets the next advance. Why do I say it's right to gain the profit from liquidation? The original version is actually a market-oriented natural node. In the process of cooperation with smart contracts, there are bound to be some market fluctuations. By default, the nodes that monitor the liquidation point will compete for the cake first. In this case, the market will derive a kind of pipeline to deal with all kinds of liquidation needs, which will make some nodes take arbitrage as the main complaint point, which obviously deviates from the open market service. What about the original intention of a good end customer? The version simply makes the existence transparent. Since the opportunity always exists, there is simply an arbitrage opportunity in winning numbers. The node service provider will participate in the liquidation on the auction, and the auction income will distribute the profits to the users of the agreement, which is equivalent to the value originally taken from the users, and now it is returned to the users. This actually opens up the commercial pattern of the market. What used to serve minority arbitrageurs has now become an opportunity for the general public to benefit. In fact, it is more than trying to upgrade the peacekeeping side. After all, the existence of the brand name is detrimental to the fair rights and interests of users in the chain, and it can really open up a new world to change the profit of serving the minority into a business pattern that benefits the public. It is really important to predict the strategic card position of the machine track, etc. Although it monopolizes a large part of the market, the dispute over the machine track has always been and there will be dark horses running out, which deserves long-term attention. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
