360 march into blockchain Technology

1.

"Local tyrant" Wang Jianlin has also come to the blockchain to join in the fun. To be exact, he has returned to the blockchain track

on the evening of March 12, centrality NZ, a New Zealand blockchain company, announced on its official website that it had reached a strategic technical cooperation with Wanda network technology group of China Wanda Group

Wang Jianlin once said publicly that the main goal of Wanda network technology group in blockchain is to use distributed ledger technology to reshape the current Internet service mode and create the next generation of value Internet infrastructure. Wanda blockchain will combine the Internet of things and big data to enable businesses to develop in a highly transparent distributed sharing environment

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

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

1. Bone is a blockchain digital currency issued by Tangshan shuisongyuan Biotechnology Co., Ltd

2. Platinum coin will be officially traded on Swiss top exchange rfinex (r net for short)

3. With the launch of platinum coin, all the procts of shuisongyuan suppliers, as well as hotels, restaurants and other instries, can join shuisongyuan blockchain and pay with platinum coin

future trend

1. In November 2016, the central bank prepared digital currency, and it is likely that cash will not exist in ten years

2. In November 2016, China digital currency Research Institute was established to cultivate high-level talents of digital currency, carry out digital currency research, consultation, development planning and related activities. It is a non-profit unit with legal license approved by relevant ministries and commissions, and is committed to promoting the integrated development of scientific research and practice of digital currency instry

Up to now, Hangzhou City, Shenzhen City and Guizhou Province have become the three hot areas for the central bank's digital currency pilot. It is reported that Hangzhou is actively promoting the planning and construction of Qiantang River financial harbor, including the blockchain instry. Hangzhou will build the first blockchain Instrial Park in China, which is located in the Internet Finance town of Xihu District, surrounded by ant financial services, e-commerce bank, Zhejiang University and its science and Technology Park and other well-known enterprises and parks

legislation

in August 2018, Elina sidorenko, an official of Russia's digital currency risk assessment department, wrote in her own telegram that a Russian digital currency bill, which takes into account social comments and the interests of enterprises and financial institutions, will be issued soon, and will clarify the rights, responsibilities and obligations of relevant participants in digital currency

5. Explain blockchain with scientific language --- blockchain is a permanent and irreversible modified record generated by superimposing encrypted data (blocks) in chronological order. Many financial institutions in the world, including JPMorgan Chase, HSBC, Citibank and New York Mellon bank, have also cooperated with blockchain companies to study the application of blockchain technology in the financial market. The person in charge of the blockchain Technology Laboratory of Shanghai Heshu software said that when there is no trusted third party in blockchain, all transaction data will be stored in a data block, and the transaction information will form a complete chain and be included in the blockchain, which is a more reliable ultimate solution than the trusted third party.

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

7. I don't know what you want to know, as far as blockchain 3.0 is concerned. At present, there is no accurate concept, or it is not completely determined. Most people think that DAPP technology represented by EOS will open "blockchain 3.0"
DAPP is the abbreviation of decentralized application, which translates into decentralized application, also known as distributed application. Compared with the app we are familiar with, DAPP does not rely on IOS and Android system development, but is put on the blockchain system and combined with smart contract. DAPP is to blockchain just as app is to IOS and Android
generally, different dapps will adopt different underlying blockchain development platforms and consensus mechanisms, or issue their own tokens, or use common tokens based on the same blockchain platform. However, DAPP can not be developed on all blockchains, but must use a public blockchain platform with smart contract function. It allows anyone to build and use distributed applications running through blockchain technology, such as Ethereum and EOS.

8. 360 will be released in the evening. It is said that Netease is now running very well. The black diamond is relatively stable. The promotion mode is also steady. It is not extreme, but it is also in the forefront. With the graal maturity of technology, it will become better and better; It was the first and popular one. At that time, it was able to lead a lot of dogs, but now it is also very popular. Each blockchain represents its own company brand, and its development will not be poor. If China's network giants can't play blockchain well, other technical forces will be poor, too...

9. Blockchain 360 blockchain is a fast-moving technology, which fundamentally changes finance, supply chain, medicine, insurance, law and commerce. Join the host, Bryant Nielson, and he just
