Outer tube block chain platform
according to Xiao Wang, the concept of blockchain as a service (baas) is mainly proposed by Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service combined with blockchain technology. For example, Microsoft's azure cloud computing platform and IBM's bluemix garage cloud platform all provide blockchain as a service baas
blockchain as a service (baas) is a space created by enterprises such as Microsoft and IBM from their own cloud service network to run a blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of baas nodes is to quickly establish the development environment they need, and provide a series of operation services based on blockchain, such as search query, transaction submission, data analysis, etc. these services can be centralized or decentralized to help developers verify their concepts and models faster. The service of baas node is reflected in: it is more instrumental and easy to create, deploy, run and monitor 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 exchangesBlockchain platforms include Ethereum, Asch and other underlying application development platforms
Ethereum, an open source public blockchain platform with smart contract function, provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)
arch, a decentralized application platform based on side chain technology. Asch is designed to lower the threshold of developers, such as using JavaScript as the application programming language and supporting relational database to store transaction data, which is believed to be very attractive to developers and small and medium-sized enterprises
extended data
in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain has become the core component of electronic currency bitcoin: public account book for all transactions
by using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently. The blockchain invented for bitcoin makes it the first digital currency to solve the problem of repeated consumption. Bitcoin's design is a source of inspiration for other applications
bitcoin is the absolute mainstream of digital currency, and digital currency is in full bloom. Bitcoin, litecoin, dogecoin, dashcoin are common. In addition to currency application, there are various derivative applications, such as Ethereum, Asch and other underlying application development platforms, as well as NXT, SIA, bitstocks, maidsafe, ripple and other instrial applications
how many stages is the blockchain divided into&# 8194;
there are 1.0, 2.0 and 3.0 blockchains, and the digital currency dominated by bitcoin is blockchain 1.0; The smart contract platform centered on Ethernet is blockchain 2.0; The application scenario and platform of high-performance blockchain is blockchain 3.0. The simple conclusion is that 1.0 is mining and currency speculation; 2.0 is ICO and currency; 3.0 is the implementation of the project. The real landing projects are still far away from us. Most projects take stage 2.0 as the entry point of instry solutions. The combination of blockchain and instry enables blockchain to be applied in a certain instry&# 8194;
how to be a qualified blockchain project&# 8194; potential blockchain projects have different evaluation standards and different periods. The main reason for the outbreak of digital currency in 2017 is the promotion of ICO and Ethernet smart contract. In the past, projects that could meet these two conditions were considered good. Now, the measurement standard of projects is: & (1) There are application scenarios. The project itself has team, goal and real scene application. Because some teams or enterprises are not suitable for blockchain applications, it is a rather crude way to establish a connection between them&# 8194;&# 8194;&# 8194;&# 8194;&# 8194; (2) the multi parties involved in the blockchain can generate transactions (3) blockchain has a large number of communities and users. In conclusion, good blockchain projects can be applied refer to the case of Henan keoo Information Technology Co., Ltd
cross border payment, supply chain finance, insurance, digital bill, asset securitization, bank credit reference and other fields
① cross border payment. Due to the characteristics of disintermediation of blockchain, openness, transparency and non tampering of transactions, no third-party payment institutions join in, which shortens the payment cycle, reces costs and increases the transparency of transactions< (2) digital bill. Blockchain has the characteristics of disintermediation, system stability, consensus mechanism and tamper proof, which can rece the operational risk, market risk and moral risk in the traditional centralized system< (3) credit management. In the field of credit investigation, blockchain has the characteristics of decentralization, distrust, timestamp, asymmetric encryption and smart contract, which ensures that limited and controllable credit data sharing and verification can be realized on the basis of effective protection of data privacy< (4) asset securitization. The characteristics of blockchain disintermediation, consensus mechanism and non tampering can increase the efficiency of data flow, rece costs, monitor the real situation of assets in real time, and ensure the trust of all parties in the transaction chain on the underlying assets< (5) supply chain finance. Due to the characteristics of disintermediation, consensus mechanism and non tampering of blockchain, it does not need a third-party credit enhancement agency to verify the authenticity of various relevant vouchers on the supply chain, so as to rece the financing cost and financing cycle< (6) insurance business. With the development of blockchain technology, personal health status, accident records and other information may be uploaded to the blockchain in the future, so that insurance companies can obtain risk information more timely and accurately when customers take out insurance, so as to rece underwriting costs and improve efficiency. The sharing transparency of blockchain reces the information asymmetry and the risk of adverse selection; The characteristics of its history can be traced, which is concive to recing the moral hazard, thus recing the difficulty and cost of insurance management.
the suggestion is to redo the system, and then find the guardian God to reinforce the system security for you, so as to completely plug the loopholes.
