Interconnect_Blockchain One Year On

Hyperledger is a collaborative effort created by the Linux Foundation to advance blockchain technology for use by enterprises. It aims to create an open standard for distributed ledgers that can transform global business transactions. The project will develop an enterprise-grade open source distributed ledger framework and codebase that users can build industry applications on. It will also create a technical community to benefit solution providers and users focused on blockchain use cases.

This document provides an agenda and overview of IBM Bluemix and Cloud Foundry. The agenda includes introductions to Platform as a Service (PaaS), Cloud Foundry, exploring the Bluemix console, and creating and updating an app. It then discusses the history and models of Infrastructure as a Service (IaaS) and PaaS, the architecture and benefits of Cloud Foundry, and how to use the Bluemix console to create an app from the catalog and edit code locally.

Bitcoin: A Peer-to-Peer Electronic Cash System Satoshi Nakamoto satoshin@gmx.com www.bitcoin.org Abstract. A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power. As long as a majority of CPU power is controlled by nodes that are not cooperating to attack the network, they'll generate the longest chain and outpace attackers. The network itself requires minimal structure. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone.

The document outlines IBM's engagement model for helping customers explore blockchain, build proofs of concept, and scale blockchain applications. It positions IBM as supporting the open source Hyperledger project and providing tools and services to make blockchain adoption easier for businesses.

Blockchain Explained - An Introduction to Blockchain for Business. Presentation by Mikael Haglund, CTO IBM Sweden, held at Watson Sweden Summit 2017

Blockchain technology was introduced in 2008 through Satoshi Nakamoto's white paper that introduced blockchain as a distributed database that maintains a continuously growing list of transaction records hardened against tampering. The document discusses key definitions around permissioned versus permissionless blockchains and consensus algorithms. It also provides examples of potential business use cases for blockchain as well as success stories from companies applying the technology.

Distributed ledgers offer advantages for capital markets by providing a single record of transactions maintained across multiple nodes, avoiding political battles over control. They could help reconcile complex transactions recorded across old, fragile software systems in bank back offices. A distributed ledger maintained between different financial players could more easily track a swap sold and resold between custodians than traditional systems. Potential use cases involve a lack of central authority, robust regulatory needs, and transactional processes followable as smart contracts. Examples include repo agreements, FX settlement, and trade reconciliations.

Foreword This paper is the result of a research project carried out by Labs in EVRY Financial Services during the fall of 2015. The content of this report is the result of a comprehensive study, featuring online sources, literary works, as well as recordings of financial conferences such as Consensus 2015 and Fintech Week 2015. We aim to provide a comprehensive report detailing the opportunities, challenges and key success factors for financial institutions looking to leverage the opportunities presented by blockchain technology. We hope you enjoy this study and that it helps give you greater understanding.

An introduction to Blockchain for Business, as well as a deep dive into the IBM Blockchain Platform, its underpinning technologies, as well as various tools and frameworks that can guide developers towards building applications on top of a running business network.

Blockchain is a shared, replicated ledger technology that can open up business networks by reducing costs, improving efficiencies, and increasing accessibility. IBM supports an open standards, open source, open governance blockchain and is a member of the Linux Foundation Hyperledger project, which is developing open source shared ledger technology. IBM offers customers an engagement model to explore blockchain applications through conversation, demonstrations, proofs of technology, and first projects to help get customers started using blockchain now.

Hyperledger is an open source collaborative effort created to advance cross-industry blockchain technologies. It includes various blockchain frameworks, platforms and libraries for building blockchain applications and solutions. The Linux Foundation hosts the collaboration to provide an open, neutral environment for technical governance. Hyperledger aims to support blockchain applications across different sectors through standards, an open developer community, and enterprise-grade frameworks.

Blockchain technologies can enable trusted transactions by providing a distributed digital ledger of transactions and asset transfers. The document discusses several use cases of blockchain including enabling global payments, improving supply chain visibility and traceability, facilitating trade finance and private equity administration, and addressing challenges in renewable energy flexibility and aircraft maintenance records. Blockchain allows for near real-time sharing of information across organizations on a secure immutable platform.

Blockchain technology is poised to significantly impact IT audit functions and identity management. It allows for digital records and asset exchanges without intermediaries through distributed ledgers and smart contracts. Several industries are investing in blockchain implementations for applications like banking, supply chain, and healthcare. However, challenges include integrating the immature technology, determining its regulatory status, addressing concerns over control and privacy, and reducing its large energy usage. The document discusses how blockchain could streamline compliance while shifting identity management, and offers ways for IT auditors to engage with blockchain alliances and communities.

Blockchain technology is increasingly being considered for applications in business contexts due to its key properties. It is also very much hyped for its potential to transform existing industries and business models. In Part 1, we will introduce the key properties of blockchain, its limitations, the field and the relevance for SAP and enterprises in general. In Part 2, we will focus on one of the prominent suites available today and provide an demonstration of the POC we’ve developed.

This document discusses how "Trailblazers" in the financial markets industry, which make up 14% of respondents in a survey, are early adopters of blockchain technology who expect to have blockchain solutions in commercial production and at scale by 2017. The document outlines key findings about the Trailblazers, including that they prioritize reducing costs through blockchain in areas like wholesale payments, clearing and settlements, and reference data. While most financial institutions do not expect much disruption from blockchain, the Trailblazers see opportunities for new business models in areas like equity and debt issuance.

Blockchain explained is a document that introduces blockchain technology for business use. It discusses how blockchain can help solve inefficiencies in sharing records between participants in a business network by providing a shared, replicated ledger. It describes different types of blockchains and requirements for business blockchains, including how they handle assets, identity, and transaction endorsement. The document provides examples of IBM blockchain networks and solutions and how IBM can help organizations create or join networks to address business challenges through blockchain.
