Work package 3 sets the basis for the technical implementation of EUNOMIA by identifying the technical requirements and producing the specifications and architecture design. WP3 also progresses with the setup of the technical infrastructures and frameworks that will allow the development, operation and evaluation of the tools and prototypes of WP4. The scope of the current deliverable 3.1 is to identify the technical requirements and the actors/services of the EUNOMIA platform. The functional and non-functional requirements were extracted and analysed in deliverable 2.4: “User needs and requirements”, as well as the actors/services. In total, 26 actors, 61 functional and 21 non-functional requirements were identified. These will guide the development of all technical components in the project directly and indirectly by informing the specifications and architecture. Also, this deliverable documents the state-of-the-art technologies to be implemented, which are: blockchain infrastructure, content and context analysis, human-as-trust-sensor and user reputation mechanism, cybersecurity and privacy framework, digital companion and peer-to-peer infrastructure. @Copyright of EUNOMIA Consortium Page iii ` TABLE OF CONTENTS DOCUMENT INFORMATION ........................................................................................................ ii VERSION HISTORY ......................................................................................................................... ii AUTHORS......................................................................................................................................... ii REVIEWERS ...................................................................................................................................... ii Executive Summary ....................................................................................................................... iii Table of Contents .......................................................................................................................... iv List of Figures ................................................................................................................................. iv List of Tables.................................................................................................................................... v List of Acronyms and Abbreviations .......................................................................................... vi 1.

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.

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.

  • Hyperledger Whitepaper
    Paper updates https://docs.google.com/document/d/1Z4M_qwILLRehPbVRUsJ3OF8Iir-gqS-ZYe7W-LE9gnE/edit#heading=h.m6iml6hqrnm2 Hyperledger Whitepaper Abstract This paper describes industry use cases that drive the principles behind a new blockchain fabric, and outlines the basic requirements and high­level architecture based on those use cases. 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

    Leading the digital value revolution BEYOND BLOCKCHAIN: WHAT IT REALLY MEANS FOR TECHNOLOGY AND BUSINESS POSSIBILITIES OF BLOCKCHAIN What is Blockchain 03 How Blockchain is different from a conventional system 04 What can be enabled by Blockchain 05 OUR UNDERSTANDING Beyond the Hype 07 Blockchain features vs business model 08 Opportunity 09 Social changes 10 NTTD tech and foresight 11 OUR CAPABILITIES Strengths & skills 13 Collaborations & alliances 14 Our design approach 15 MAIN USE CASES UNDERTAKEN BY NTT DATA Summary 17 JAPAN 18 ITALY 20 SPAIN 22 UK 24 USA 25 2 SUMMARY Some talk about Blockchain and its potential, new technologies and the transformations leveraged by innovation. 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.
