1. blockchain platform, do you want to see blockchain information? Here is Amway password finance, general chain circle, coin circle, DAPP and other information.
2. There are few real baas that have been approved by the state. At present, the mainstream platforms are Tencent's tbaas, Jingdong Zhizhen chain jdchain, ant blockchain baas, Rongze's rbaas, network's Intelligent Cloud and Huawei's cloud BCS. Among them, the top four baas platforms are teams that have been researching and developing blockchain technology for several years, R & D capabilities are very strong.
3. Like IAAs, PAAS and other concepts, baas tends to be within the scope of public cloud, while enterprise services need to consider more customized requirements. Based on the practical experience of enterprise users for many years, chainnova is starting to build solutions from two aspects: public cloud and hybrid cloud (Enterprise Cloud Service). At present, with AWS and other well-known cloud service providers at home and abroad, we are ready to launch systematic service solutions, hoping to bring more flexible, more perfect and more powerful technical capabilities to customers. The purpose of building such a blockchain technology capability platform is, of course, to help customers solve problems better. In the financial field, chainnova is cooperating with instry leaders such as IBM to create end-to-end instry solutions with the help of their rich experience in financial instry scenarios.
4. Renren blockchain service enables users to quickly build their own IT infrastructure and blockchain services on an elastic and open cloud platform. Using baas can greatly rece the cost of realizing the underlying technology of the blockchain, simplify the construction and operation and maintenance of the blockchain. At the same time, facing various instry scenarios, it can meet the personalized needs of users and quickly deliver customized baas in one stop.
5. He has relevant requirements for performance, high availability, security and disaster recovery. In fact, you are also considering the requirements of your platform. In fact, these things are often not standardized things. On the contrary, they are things that some enterprises are facing. The main purpose is to use the secondary development for enterprises in the enterprise landing scenario. For example, chainnova turns some of its precipitated things into APIs and puts them on this platform instead of turning them into a cloud for external use.
6. It should be a cloud service solution combined with blockchain technology. It is also a systematic service solution launched by some well-known service providers in China. It has the ability to build such baas platform based on the underlying technology of blockchain, such as Tencent tbaas, network intelligent cloud and Jiangsu Rongze rbaas.
7. The official way of purchase will be announced, including player cloud, extreme route, Xiaomi and 360. At present, I am paying attention to the recent jCG K3 blockchain route. Compared with the playing method of
digital currency, the revenue of shared CDN business is stable, which is linked to the broadband upload speed, and
mining is converted into currency. Compared with the old mining area, mining in the new mining area will be much easier, mainly because of the old brand and high reliability. But we also need to consider the risk, it depends on indivial decision-making.
8. 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

9. 1. First of all, we can enter the self-service teller machine of ICBC to find a deposit machine or an all-in-one machine for deposit and withdrawal
