Development Of Internet Commonweal Goods Based On Block Chain Technology

With the rapid development of the current technology,there are many innovations in the industry.Following the big data,cloud computing and other technologies,the concept of the block chain rises quickly in 2015,the related news of block chain and the global financial institutions are appearing constantly.More institutions and businesses began to use the technology of block chain.The emergence of block chain achieves the transfer of information from the Internet to the value of the Internet,it provides a new credit creation mechanism.As the underlying technology of digital currency(bitcoin),the block chain technology has attracted extensive attention in the financial world,including HSBC,JP Morgan,Goldman Sachs,Citibank,Bank of New York Mellon,Barclays Bank,UBS,Morgan Stanley(UBS),Royal Bank of Scotland and a number of financial institutions.They are corporating with block chain companies to study the application and development of block chain technology in financial markets.The world economic forum is a bold prediction that by 2027,10% of the world's GDP will be stored in the block chain network.According to the features of block chain technology,for the weakness of now public assistance projects,block chain is taken as the underlying data books,finishing the generation of data inference.It can both technically protect the authenticity of public data,but also help public projects to save the cost of information disclosure.In addition,it can solve the problem of low transparency triggered by the crisis of confidence,and it is dispeling the public's enthusiasm and confidence in China's charity.In this paper,the following work has been carried out:1.We study the basic concept of the underlying block chain,the structure of the block,the link between blocks,the public key encryption mechanism.2.The operation principle of the blockchain,including its working process,and solving the double problem of chain block,Byzantine Generals issues.This paper introduces three kinds of common mechanism of block chain,which are Proof of Work(PoW),Proof of Stock(PoS)and the Delegate Proof of Stake(DPoS).It is analyzed of the advantages and disadvantages of various consensus algorithms in different scenarios.3.It introduces a large number of domestic and foreign use of the chain of the two blocks of the platform: Ethernet square and the block chain.And the application of intelligent contract in block chain platform.It built a block chain test in the local environment,wrote tokens intelligent contract,deploy of smart contracts and de centralized applications.4.This paper introduces the design of public welfare projects,including the bottom of the block chain architecture,web system architecture,security design,scalability design and database design.According to the characteristics of the Internet project,we design the architecture to meet the needs,and do not make exceeding design.5.This paper introduces the modular design and implementation of the system,through the test to verify the various needs of the use cases to meet the original intention of the design.In this paper,the research of block chain technology and the preparation of intelligent contract is an innovation and revolution of human social credit creation.In theory,under the premise of sufficient technical capacity,it can make both sides of the transaction no longer need to use the third party platform to expand economic activities,so as to realize the global low-cost transfer of value.
