In open finance, you need an open OKLink.

The DeFi craze continues to rage, while the high yield myth spreads, security incidents are the biggest risk.

On The same day, Sept. 2, Certik, PeckShield and Slow Fog Technologies, three blockchain security companies, all noted the risks of DeFi Markets Swap copy. According to PeckShield situational awareness platform, in August of this year, there were 28 prominent security incidents across the blockchain ecosystem, involving DeFi 8, wallet security 2, public chain security 6, exchange related 1, extortion related 4, and racketeering 7. In the context of frequent security incidents, security is becoming a focus that the whole industry cannot ignore.

For investors, data viewing websites on the chain is a daily necessity. Both project research and project analysis need to use data on the chain, and platforms providing such services need to do more than aggregation of information.

OKLink: One-stop blockchain data site

On Aug. 30, Vitalik expressed his love for TxStreet, a linked-data visualization site, praising it as a fascinating and insightful tool. In fact, data sites have long been an important part of the cryptocurrency ecosystem, with browsers often the first data tools to appear when public links go live.

Because each transaction is open and transparent, with data on the chain, investors have access to a system like Whale ; Warning tools like Alert get the latest updates on the chain, as well as detailed information about an address and the current blockchain via sites like Ethereum and the Bitcoin browser.

And, apart from the browser, and similar DAppReview, DeBank specialized data query DApp, DeFi sites, as well as specialized query stable currency issuance information DappTotal, StablecoinIndex platform, let the user be able to extract valuable information. But for the average user, if you want to query all kinds of information in multiple dimensions, it means switching between different sites, which is not cost-effective in terms of time cost. And providing a wealth of diverse information is naturally the new trend.

In addition to the currency, the etheric fang, such as data blocks, chain, chain OuKeYun OKLink also provides Wright coin, BCH, DASH, bitcoins SV, USDT, ETC and OKChain testing data, from the basis of the conventional data, including the entire network to calculate the force, the difficulty and the reward, block height, market value, turnover, volume, TPS, at the same time, the mineral pools work force, rich address and other data on the user's concern, also has realized the data visualization.

In early August, OKLink launched DeFi, which contains data on mortgage lending, DEX, derivatives, payments, and assets. By entering OKLink ETH's browser entry, users can query DeFi's real-time data on ethereum, including the total number of locks on Ethereum and the percentage of locks on its products and services.

On September 1, OKLink launched its "Sky Eye on the Chain" section, opening its online data tracking system to the public to help users or law enforcement agencies locate the flow of money and the movement of money between addresses. Rhythmical BlockBeats summarizes the types of products and functions currently on the market, as shown in the figure below:

As can be seen from the figure above, some platforms do not offer free trade analysis data to the public. According to an industry insider, the reason is that "this part of data is not a simple summary, but after in-depth integration and cleaning, the relevant database will be clearer and clearer." The chain on the sky eye free open trading map and address analysis of the two query directions, and support nearly a month within the three data query, to provide transparent information and services.

From the perspective of data richness, OKLink provides users with fast, accurate and comprehensive on-chain data services. More importantly, behind the open and transparent on-chain data solution, there is the improvement of blockchain security.

Eye on the Chain: Making encryption compliance a step closer

Since the beginning of this year, there have been dozens of security incidents in the global cryptocurrency market, among which, in the case of being attacked by hackers, it has gradually become a routine operation for the cryptocurrency trading platform to help freeze relevant suspicious addresses, and compliance has become a new important subject for the trading platform. For trading platforms, in addition to regular authentication and anti-money laundering initiatives such as KYC and AML, monitoring and warning of cryptocurrency addresses is also an important part of the effort.

As far as OKLink is concerned, the browser that serves as a regular data query entry point is standard, while the "sky eye on the chain" is a further extension of the security aspect on the chain. Through the trading map function of "Sky eye on the Chain", we only need to input the trade hash we want to query, set the corresponding parameters, and then we can easily get the visual map of the trade, and easily understand the cause and cause of capital flows.

We can use the example of the Plustoken event to show how the sky eye on the chain makes the data transparent. It can be found from the following figure that after the members of Ponzi scheme Plustoken team ran away, the fund in the official wallet has been cleaned and transferred for many times. Skyeye on the chain has made the whole circulation process into a visual figure hierarchically, and provided a download button for users to check.

As long as the user places the cursor above the desired address, information such as the current balance, first transaction time, transaction times and cumulative received and sent amount of the address can be displayed in the upper left corner. Users can also make a specific analysis of an address and add it to the list for real-time monitoring. As long as the range of balance changes is set well, the first email notification can be obtained when funds are transferred, so as to avoid the trouble of continuous monitoring of human flesh. In addition, the "address tracking" feature allows users to easily track the flow of money along the chain.

Behind the seemingly simple and clear data presentation is the integration and cleaning of massive data. "The focus and difficulty of data analysis on the chain is to mine the association relationship between accounts/addresses. OKLink officials have introduced that, taking BTC as an example, the daily number of active addresses should be calculated from the transaction data on the chain first, then the market value of BTC should be obtained at the corresponding time, and then the relationship between the market value of Bitcoin and the number of active addresses should be established by log-linear fitting.

In fact, in addition to assisting individual investment, this feature also has rich application scenarios in tracking stolen digital assets, transaction traceability, and AML anti-money laundering. In March this year, the "Room N" incident was exposed. A number of trading platforms cooperated with the police to trace and confirm the addresses of the bitcoin and Ethereum accounts involved, and finally identified the two parties involved and determined the total amount involved.

It is understood that in addition to existing functions, OKLink has planned to support data monitoring of more currencies for a period of time in the future, provide more comprehensive data services on the multi-dimensional chain, and help build a complete protection system for the entire blockchain ecological application. Even in the event of a security incident, it can quickly locate problems and troubleshoot.

The feverish enthusiasm for investing in the market has masked the DeFi ecology with frequent security vulnerabilities. In addition, the still active dark web market, cryptography scams and contract vulnerabilities are also hard to ignore in the current situation, and compliance has become an inevitable key issue for trading platforms.

Today, block chain browser has from a basic data query tool, gradually extends to the investment analysis, chain track, anti-money laundering, such as full-service tool, be block chain + large data is an important part of the solution, with similar OKLink products more and more, the security of the whole chain block industry will also be effectively promoted, and the market circulation of trading information more transparent, distance are a step closer to compliance means that the whole industry.
