A Study of Blockchain Framework–Hyperledger Fabric and Implementation as Educational Network by Venkata Ayyappa Devarasetty A Starred Paper Submitted to the Graduate Faculty of St. Cloud State University in Partial Fulfillment of the Requirements for the Degree of Master of Science in Information Assurance December, 2019 Starred Paper Committee: Abdullah Abu Hussein, Chairperson Lynn Collen Sneh Kalia 2 Abstract Blockchain, the foundation for Bitcoin, has gained lots of attention recently. Blockchain works as a distributed ledger technology that allows information exchange to take place in a distributed way, and ledger is immutable. Blockchain database removes the necessity of the centralized system; therefore, applications based on Blockchain are getting high in number. This paper covers an discuss in detail of blockchain technology, and its consensus algorithms along with workflow, how trust has will be upon a system having no centralized system. This paper also studies various frameworks being built upon the blockchain systems and how they are helpful in solving many organizational issues and Developing of an application on an existing blockchain framework which is an access based system, has information regarding academic records, certifications and eligibility requirement examination records belong to a person, who can share with any organization, eliminating the need of physical documents.

The number of cryptocurrencies has increased from about 2,000, with a market capitalization of over $200 billion in late 2017, to over 8,000, with a market capitalization of about $1.6 trillion. For context, the market capitalization of global equities is about $110 trillion, that of the S&P 500 stocks is $35 trillion and that of US Treasuries is $22 trillion. Reported trading volume in cryptocurrencies, as represented by the two largest cryptocurrencies by market capitalization, has increased sixfold, from an estimated $6.8 billion per day in late 2017 to $48.6 billion per day in May 2021.1 This data is based on what is called “clean data” from Coin Metrics; the total reported trading volume is significantly higher, but much of it is artificially inflated.2,3 For context, trading volume on US equity exchanges doubled over the same period.

    Hyperledger Architecture, Volume II Smart Contracts This is the second in a series of papers from the Hyperledger Architecture Working Group (WG). These papers describe a generalized reference architecture for permissioned blockchain networks and share the recommendations of the Hyperledger Architecture WG with the end goal of guiding all Hyperledger projects towards modular designs. These papers also serve as a vendor-neutral resource for technical blockchain users and developers interested in using permissioned blockchain networks. About this paper This paper on smart contracts provides a generalized reference architecture for smart contracts. The paper also explores how various Hyperledger blockchain frameworks—namely Burrow, Fabric, Indy, and Sawtooth—implement the reference architecture. Other papers in this series The first paper in this series introduced the Hyperledger business blockchain design philosophy and provided a generalized reference architecture for consensus.

  • A Time Bank System Design on the Basis of Hyperledger Fabric Blockchain
    future internet Article A Time Bank System Design on the Basis of Hyperledger Fabric Blockchain Yu-Tse Lee 1, Jhan-Jia Lin 1, Jane Yung-Jen Hsu 2 and Ja-Ling Wu 2,* 1 Department of Electrical Engineering, National Taiwan University, Taipei 106, Taiwan; [email protected] (Y.-T.L.); [email protected] (J.-J.L.) 2 Department of Computer Science and Information Engineering, National Taiwan University, Taipei 106, Taiwan; [email protected] * Correspondence: [email protected] Received: 10 April 2020; Accepted: 7 May 2020; Published: 8 May 2020 Abstract: This paper presents a blockchain-based time bank system on the basis of the Hyperledger Fabric framework, which is one of the permissioned blockchain networks. Most of the services provided by existing Time Bank systems were recorded and conducted manually in the past; furthermore, jobs for matching services with receivers were managed by people. Running a time bank in this way will cost lots of time and human resources and, worse, it lacks security. This work designs and realizes a time bank system enabling all the service-related processes being executed and recorded on a blockchain. The matching between services’ supply-and-demand tasks can directly be done through autonomous smart contracts. Building a time bank system on blockchain benefits the transaction of time credit which plays the role of digital currency on the system. In addition, the proposed time bank also retains a grading system, allowing its members to give each other a grade for reflecting their degrees of satisfaction about the results provided by the system.

The design presented here describes this evolving blockchain fabric, called Hyperledger, as a protocol for business­to­business and ​ ​ business­to­customer transactions. Hyperledger allows for compliance with regulations, while supporting the varied requirements that arise when competing businesses work together on the same network. The central elements of this specification (described below) are smart contracts (a.k.a. chaincode), digital assets, record repositories, a decentralized consensus­based network, and cryptographic security. To these blockchain staples, industry requirements for performance, verified identities, private and confidential transactions, and a pluggable consensus model have been added. For questions regarding Hyperledger terminology, check out our glossary. ​ ​ Background Blockchain is an emerging technology pattern that can radically improve banking, ​ supply­chain, and other transaction networks, creating new opportunities for innovation and growth while reducing the cost and risk of related business operations. With the rapid emergence of Bitcoin in the transactions domain since 2009, many businesses and industries have invested significant resources in investigating the underlying

But what does it really mean? NTT DATA’s foresight technologies, including Blockchain, are based on observation, studies, measurements and prototyping or implementations, which gives us the ability to turn possibilities into reality and to understand the level of maturity of technologies capable of transforming processes, systems and businesses. We are presenting our capabilities and real use cases implemented by our dedicated Blockchain team around the world. NTT DATA is exploring all of the Blockchain arena, working with a multi-platform approach. These are facts which go beyond the hype and give an “objective vision” of what we can do and what we are not yet able to do with these new technologies, how they are impacting on social changes and how you can come to understand Blockchain features and achieve something tangible and concretely implementable. 1 Possibilities of Blockchain 2 WHAT IS BLOCKCHAIN? The concept of Blockchain started when Satoshi Nakamoto created Bitcoin in 2008-2009, designing a new system that could allow the creation and transfer of electronic cash without BLOCKCHAIN trusting any central authority.
