Hong Kong 360 blockchain
1. Jinrong China Financial Instry Co., Ltd.
this is a digital currency trading platform in Hong Kong. At the beginning of trading, it developed on the principle of safeguarding the rights and interests of customers. Similarly, in order to expand trading customers, the company launched the privilege of opening accounts free of charge, and gave customers some concessions in some festivals, This is an important reason why the enterprise takes the first place in the domestic formal blockchain platform
2. Bitfinex
is a digital currency trading platform in Hong Kong, China. It is one of the largest cryptocurrency exchanges in the world. It occupies an important position in the world's cryptocurrency trading and circulation. It also provides the world's most liquid registration policy and plays an important role in the world's trading operations, At present, it occupies the second place in the domestic regular blockchain platform
3. Fire coin network
this is an earlier digital currency trading platform in China, mainly trading bitcoin. As the third instry of domestic regular blockchain platform, it is the trading platform with the largest bitcoin trading volume in China. Many new digital asset trading platforms have been developed under the company, For the future development of the foundation
This is a digital currency trading platform jointly established by some digital currency enthusiasts, and its founder is Zhao CHANGPENG. In fact, this trading platform didn't attract much attention at the beginning. With the continuous operation of the company and the founder's understanding of digital currency, this enterprise has become the top four domestic regular blockchain platforms, which shows the power of this platform This is one of the most popular digital asset trading platforms in the world. There are many kinds of digital currencies for trading, and their main functions are cash out and derivative trading. They are well-known in the world's exchangesRecently, Vulcan team of 360 company found a series of high-risk security vulnerabilities in EOS, a blockchain platform. It is verified that some of the vulnerabilities can remotely execute arbitrary code on EOS nodes, that is, they can directly control and take over all nodes running on EOS through remote attacks
In the early morning of May 29, 360 reported this kind of vulnerability to EOS official for the first time, and assisted it to repair the security risks. The person in charge of the EOS network said that the EOS network will not be officially launched until these problems are fixed
EOS super node attack: the virtual currency transaction is completely controlled
in the attack, the attacker will construct and publish a smart contract containing malicious code, and the EOS super node will execute the malicious contract and trigger the security vulnerability. The attacker then uses the super node to pack the malicious contract into a new block, resulting in the remote control of all nodes in the network (alternative super node, exchange recharge withdrawal node, digital currency wallet server node, etc.)
because the system of the node has been completely controlled, the attacker can "do whatever he wants", such as stealing the key of the EOS super node and controlling the virtual currency transaction of the EOS network; Obtain other financial and privacy data in the participating node system of EOS network, such as digital currency in the exchange, user key stored in the wallet, key user information and privacy data, etc
What's more, an attacker can turn a node in the EOS network into a member of a botnet, launch a network attack, or become a free "miner" to extract other digital currency

because the mining machine has a service life, in order to ensure that the computing power does not decline, it only provides a 2-year lease term
Ripple / XRP can't be g, but recently ripplelab team participated in WCG project (by contributing their remaining computer computing power to solve some scientific research calculation problems such as cancer, love death and so on). You need to take part in it, and ripplelab will give you some XRP according to your contribution
reborn coin is the base currency of ripple network. It can circulate in the entire ripple network, with a total amount of 100 billion, and graally decreases with the increase of transactions. The operating company of reborn coin is ripple labs (formerly known as opencoin)
reborn currency is the only common currency in ripple system, which is different from other currencies in ripple system. Other currencies such as CNY and USD can't withdraw cash across gateway. In other words, CNY issued by gateway a can only withdraw cash at gateway A. if you want to withdraw cash at gateway B, you must convert it into CNY issued by gateway B through the registration function of ripple system. However, reborn coin has no such limitation at all. It is universal in ripple system
like bitcoin, XRP is a digital currency based on Mathematics and cryptography, but different from bitcoin, XRP has the main bridge currency and security function in ripple system, and the security function is indispensable, which requires that the gateway participating in this protocol must hold a small amount of XRP
Further information:because ripple labs officials do not care about the price of the currency, and do not want people to make the price of the currency rise greatly in the short term through speculation, but hope that people can slowly accept the currency by understanding the ripple agreement, Therefore, the price fluctuation of reborn currency may be smaller than other virtual currencies, but in the long run, its price will graally show up with the development of ripple agreement, but any investment is risky. It is suggested that we invest rationally and make a reasonable judgment on its value

It was reported on May 29 that recently, Vulcan team of 360 company found a series of high-risk security vulnerabilities in EOS, a blockchain platform. It is verified that some of the vulnerabilities can remotely execute arbitrary code on EOS nodes, that is, they can directly control and take over all nodes running on EOS through remote attacks
the hidden dangers of blockchain network security need to be paid attention to
EOS is a new blockchain platform known as "blockchain 3.0". At present, its token market value is as high as 69 billion yuan, ranking fifth in the global market value
in the blockchain network and digital currency system, nodes, wallets, mines, exchanges and smart contracts all have many attack surfaces. 360 security team has found and exposed several serious security vulnerabilities for digital currency nodes, wallets, mines and smart contracts
this time, the 360 security team found a series of new security vulnerabilities in the smart contract virtual machine of EOS platform, which is a series of unprecedented security risks. No security researchers have found such problems before. This type of security problem not only affects EOS, but also may affect other types of blockchain platforms and virtual currency applications
360 expressed the hope that through the discovery and disclosure of this vulnerability, the blockchain instry and security peers will pay more attention to the security of such issues, and jointly enhance the security of the blockchain network
