The underlying platform of blockchain

1. In many cases of blockchain commercial application, we can always see the word baas. Baas is the abbreviation of blockchain as a service, which is translated into "blockchain as a service" in Chinese. So what is blockchain as a service baas? With this question, we will follow Xiao Wang of Renren blockchain technology team to discuss it carefully
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.

2. Blockchain is just a technology that anyone can use. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system. There is no underlying platform for blockchain now. If there is R3, it should be regarded as one. Decent, bitcoin and Ethereum are all relatively successful projects

3. LF CEO Ma Haobo said in the "cannon interview": the problems urgently solved by the underlying facilities of the next generation blockchain are very similar to those of Ethereum. It is an underlying decentralized computing platform. On the platform, users can easily deploy smart contracts and run them, but? LF thinks that Ethereum has three problems and hopes to solve them. The first is its overall low performance and TPS; Second, resources are not isolated. When crowdfunding for a certain contract is very popular, Ethereum network will block and other contracts cannot be executed; The third problem is reflected in the governance structure, who this blockchain belongs to, how it develops, and how to solve the problem of bifurcation.

4. There are many domestic enterprises providing the underlying technology platform of blockchain. At present, many domestic enterprises have entered the blockchain. Well known are Wanda, LETV finance, ant financial services, Ping An Bank, Minsheng Bank, postal bank, etc
of course, the most substantial progress has been made by coin Ying China, which has introced blockchain and digital currency into the crowdfunding instry. At present, a crowdfunding project has been successfully completed.

5. 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.

Blockchain 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

7. Before we mentioned the decentralized application platform, we always thought of foreign blockchain solutions. But when we talk about this topic today, we think more of our domestic laikelib. Shanghai Heshu software's laikelib blockchain technology infrastructure is a decentralized blockchain application development platform, which aims to help developers quickly create decentralized applications. Laikelib is easy to use, flexible, convenient and safe. In terms of mode, it is similar to Ethereum and belongs to the underlying technical architecture service of blockchain, but the implementation mechanism is slightly different, which can be found on the official website of Heshu blockchain technology.

8. The second type of blockchain projects is platform type. What are the characteristics of platform type blockchain projects? What are the typical representatives
the second category of blockchain projects is platform. The main function of platform projects is to establish a technical platform to meet the technical requirements of various blockchain application development
in short, platform applications allow developers to directly issue digital assets and write smart contracts on the blockchain. Smart contract is a computer program running on the blockchain database, which can be executed by itself under the condition of meeting the source code setting
for example, you develop a smart contract based on the house rent protocol on the blockchain. When the owner receives the rent, it will trigger automatic execution and give the security key of the apartment to the tenant
the main function of platform blockchain projects is to establish the underlying technology platform, so that developers can do application development on the underlying technology platform. A considerable number of platforms are still in the development state. As of January 2018, Ethereum has the largest market value.

9. There are many platforms for job intention, such as 58 city, ganji.com, zhaopin.com, Zhonghua yingcai.com, etc

10. Laikelib main chain: the main chain of laikelib mainly deals with the interaction between the application business model and the application scenario. Laikelib side chain: around the main chain, any application system can be developed in the side chain for users to use.
