Toward a self-learned Smart Contracts

In recent years, Blockchain technology has been highly valued and disruptive. Several researches have presented a merge between blockchain and current application i.e. medical, supply chain, and e-commerce. Although Blockchain architecture does not have a standard yet, IBM, MS, AWS offer BaaS (Blockchain as a Service). In addition to the current public chains i.e. Ethereum, NEO, and Cardeno; there are some differences between several public ledgers in terms of development and architecture. This paper introduces the main factors that affect integration of Artificial Intelligence with Blockchain. As well as, how it could be integrated for forecasting and automating; building self-regulated chain.Comment:

Harvey: A Greybox Fuzzer for Smart Contracts

We present Harvey, an industrial greybox fuzzer for smart contracts, which are programs managing accounts on a blockchain. Greybox fuzzing is a lightweight test-generation approach that effectively detects bugs and security vulnerabilities. However, greybox fuzzers randomly mutate program inputs to exercise new paths; this makes it challenging to cover code that is guarded by narrow checks, which are satisfied by no more than a few input values. Moreover, most real-world smart contracts transition through many different states during their lifetime, e.g., for every bid in an auction. To explore these states and thereby detect deep vulnerabilities, a greybox fuzzer would need to generate sequences of contract transactions, e.g., by creating bids from multiple users, while at the same time keeping the search space and test suite tractable. In this experience paper, we explain how Harvey alleviates both challenges with two key fuzzing techniques and distill the main lessons learned. First, Harvey extends standard greybox fuzzing with a method for predicting new inputs that are more likely to cover new paths or reveal vulnerabilities in smart contracts. Second, it fuzzes transaction sequences in a targeted and demand-driven way. We have evaluated our approach on 27 real-world contracts. Our experiments show that the underlying techniques significantly increase Harvey's effectiveness in achieving high coverage and detecting vulnerabilities, in most cases orders-of-magnitude faster; they also reveal new insights about contract code.Comment: arXiv admin note: substantial text overlap with arXiv:1807.0787

Hill Physicians Medical Group: Independent Physicians Working to Improve Quality and Reduce Costs

The Paradoxical Effects of Blockchain Technology on Social Networking Practices

Blockchain technology is a promising, yet not well understood, enabler of large-scale societal and economic change. For instance, blockchain makes it possible for users to securely and profitably share content on social media platforms. In this study, w

Service Orientation and the Smart Grid state and trends

The energy market is undergoing major changes, the most notable of which is the transition from a hierarchical closed system toward a more open one highly based on a “smart” information-rich infrastructure. This transition calls for new information and communication technologies infrastructures and standards to support it. In this paper, we review the current state of affairs and the actual technologies with respect to such transition. Additionally, we highlight the contact points between the needs of the future grid and the advantages brought by service-oriented architectures.

Social Enterprise Businesses: A Strategy for Creating Good Jobs for People with Disabilities

Over the past 10 years, there has been a tremendous growth in entities known as social enterprise businesses. This approach has been particularly promising in creating new opportunities for individuals with disabilities in emerging and growth industries. Over the past five years, the Kessler Foundation's "Transition to Work" grants program has invested $18 million toward the goal of creating job opportunities for people with disabilities. This investment has included support for several social enterprise businesses in New Jersey, stemming from the Foundation's believe that these businesses have potential for increasing employment of people with disabilities

Century Services Year I Evaluation Report on the Social Business Enterprise Model

The Mid-America Institute on Poverty is conducting a three year (12/30/1999 - 12/30/2002) evaluation of Century Services employment activities and social business enterprise model. The goals of the evaluation are to provide: a clear understanding of the social business enterprise partnership model, real time information on the enterprise's impact on employees so that management may make adjustments in implementation as necessary, and outcomes-based understanding of the Century Services model as an intervention designed to improve the attitude of employees toward work, help employees develop work skills, and increase the labor force attachment of hard to employ persons

Anchored in Place: How Funders Are Helping Anchor Institutions Strengthen Local Economies

This report issued by the Funders' Network as part of their Anchors Institution Funders' Group, examines the potential these deeply rooted local enterprises hold to create lasting and sustainable change—and illustrates how funders are working with anchor institutions to create healthier, more equitable, and economically vibrant places to live and work
