Recently, with Tesla, Meitu When listed companies buy bitcoin, the price of bitcoin continues to reach new highs. At the same time, DeFi and NFT are developing rapidly, trying to gradually integrate into the modern financial system-the digital asset market seems to be welcoming the next outbreak. Under the huge wealth effect, many investors in the stock market and fund market have entered the market one after another, joining this tide of digital assets.

With the rapid expansion of the digital asset market, some industry risks are rapidly being Zooming in, especially the issue of asset security on the chain, has become a problem that hinders the development of the industry-what should I do if I enter a phishing website by mistake, my wallet is stolen, the project runs away, and the received coins involve money laundering?

In this case, industry users need a similar "Tianyancha" A professional blockchain big data tool, it can not only provide blockchain transaction information, but also trace the corresponding address identity. At the same time, it can help us sort out clues, build models, and find out the rules in complex on-chain transactions.

Sky Eye on the Chain: Assets on the Chain, Precisely Locked

2020 is a bull market for digital assets and a bull market for crypto crime.

As an industry carriage, after the rise of DeFi in the second half of 2020, it will completely Activated the digital asset industry, built tracks such as DEX, decentralized lending, and asset agreements, and successfully launched a number of high-quality projects such as Uni and Compound. At present, the locked-up amount of DeFi on the Ethereum chain has reached 58.05 billion US dollars, and the locked-up amount of leading projects such as Uniswap, Maker Dao, Compound, and Curve has exceeded 40 billion US dollars, and it is still growing steadily.

The rapid growth of DeFi has activated the development of the blockchain industry potential, but also rapidly expand asset and transaction risks. At present, crimes on the chain have developed in various forms. In addition to hackers stealing coins, there are also vicious incidents such as extortion transactions, dark web transactions, online gambling, pyramid schemes, capital disks, money laundering, and project parties running away. According to public data, last year, the total amount of criminal funds related to digital assets reached 1.9 billion U.S. dollars, and the amount of stolen coins reached 516 million U.S. dollars. Half of the stolen money incidents were related to DeFi, with a total value of 129 million U.S. dollars.

According to the "2020 Blockchain Security Situational Awareness Report" released by the National Blockchain Vulnerability Database (CNVD) in March, in 2020, security risks in the blockchain field The number of incidents reached 555, including 103 DeFi security incidents, 204 fraud/phishing incidents, 143 ransomware incidents, 31 trading platform security incidents, 41 digital wallet security incidents, 17 public chain security incidents and other security incidents. There were 16 incidents, an increase of nearly 240% compared to 2019.

Compared with trading platforms, wallets and other industry organizations, ordinary users lack technology Team support and security awareness, there are countless cases of being confused by phishing websites, emails, and losing personal property. In October last year, a user visited a fake Curve exchange website placed by a scam gang by purchasing Google advertising space, suffered a phishing attack, and lost 20 bitcoins. A month later, a Ledger wallet user was also lured to a fake official website, where 100,000 XRP were stolen.

"The wallet is still there, but the coins are gone"-this is the number Asset investor's greatest sorrow. In order to respond to the new blockchain infrastructure policy and promote the healthy development of the industry, Okey Cloud Chain, as the world's first blockchain big data company, launched the SkyEye on the chain based on the existing multi-currency blockchain browser. Services, which can escort the security of users' digital assets.

Okey Cloud Chain Sky Eye is a block chain big data The monitoring and transaction behavior visualization tool is also the first free and open tool for all users on the entire network. If there are asset security issues on the chain such as stolen coins or phishing, you can use the SkyEye on the chain to conduct in-depth analysis and continuous tracking of the data on the chain. Relying on rich address tag resources, we can quickly lock assets on the chain through three major functions: transaction graph, address analysis, and on-chain monitoring, so as to avoid potential risks and losses in time.

"One-click three links": address analysis, transaction graph, chain monitoring

Using rich, accurate and real-time block chain big data services, the Sky Eye on the Okeyun chain develops The three major functions of transaction map, address analysis, and chain monitoring, "one force breaks all the tricks", track the target assets through an intuitive visual map.

First of all, with the help of the SkyEye address analysis function on the chain, we can query To provide data and visualization charts after an address interacts with other addresses.

Take the incident in August last year in which 1,400 bitcoins (currently worth $78.6 million) were stolen from a Github user as an example. From a legal point of view, after the digital assets involved in the case are recovered, they should be returned to the victimized investors. However, from the perspective of execution, due to the lack of relevant technical support before, the digital assets involved in the case were laundered, making it difficult to recover the stolen assets.

But by using the transaction graph function on the chain, we only need to enter Transaction hash, set the transaction amount and number of layers according to the requirements (set 3 layers here), generate a visual map of the transaction, and track the flow of assets on the chain.

Judging from the generated map, the hacker directly split and mixed 1400 BTC into small Well, transfer to more addresses.

In addition, the Sky Eye on the Okeyun Chain also has a powerful chain on the monitoring function. Users can set address monitoring and transaction monitoring according to their needs. The former can monitor the dynamics of various addresses, while the latter can be used to monitor the funds involved in a certain transaction.

In the Github incident, we can add the hacker address to the address During the monitoring, as long as there is a transaction in the address, you will receive an email reminder, and you will know the movement of the stolen address as soon as possible.

Smart police assistance, industry" Safety Vanguard"

As the first batch of applications in the blockchain industry, Europe SkyEye has been cultivating on the Keyun chain chain for many years, and has made outstanding performances in data services, technological innovation, and intelligent police assistance.

At the tool level, SkyEye on the chain introduces complex cross-address analysis; At the algorithm level, graph computing and big data are introduced; at the system level, real-time monitoring is realized. In terms of service and technology, it has truly become the "Civil and Military Double Champion", and has been recognized by the industry many times for this reason.

In the past two years, Okey Cloud Chain has won the "Most Best Security Service Agency ", "Most Influential Security Service Agency", "Most Influential Information Technology Service Platform", won the Best Data Service Agency of the Year", "Guardian of the Year 2020" and other professional awards.

At the same time, Okey Cloud Chain does not forget corporate responsibility and social responsibility, Successfully assisted the police in Shandong, Shanghai, Jiangsu and other places to detect digital asset-related cases, and received multiple thank-you letters to thank Okey Cloud Chain for its contribution to combating crimes in the digital asset field and maintaining national financial security, and has accumulated rich experience Based on the practical experience in solving cases and the basis of police cooperation, it is professional, leading, safe and reliable.

With the cutting-edge concepts of blockchain such as Bitcoin, DeFi, and NFT Gradually entering the public's field of vision, digital asset security issues are emerging in an endless stream. In order to better protect the security of digital assets, users and the industry should further strengthen their awareness of risk prevention while making good use of the SkyEye on the Okey Cloud Chain, so as to truly achieve " Both internally and externally” to jointly build a healthy and safe industry environment.
