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.

This document provides an overview of blockchain technologies and how IBM can help businesses apply blockchain. It defines key blockchain concepts like shared ledgers, smart contracts, consensus, and privacy. It also discusses example use cases for blockchain like supply chain management, financial transactions, and regulatory compliance. 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 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 through contributions to the Linux Foundation Hyperledger project, which is developing shared ledger technology. IBM offers customers an engagement model to explore blockchain concepts, show proof of technology applications, and integrate blockchain solutions into their enterprise systems.

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.

An experienced team including former consultants from IBM and CSC is launching a new SaaS platform called Loansquare to digitize financing activities for banks, corporations, and municipalities. Loansquare aims to improve processes in the structured finance sector by providing a multi-bank portal for clients, digitizing interactions, and standardizing data. The platform offers services for deal origination, syndication, servicing, and more. Loansquare is currently in development with 50+ prospects and plans to go live in Q3 2017. The company also sees potential to leverage blockchain technology for the platform going forward.

Blockchain is a shared, replicated ledger technology that can open up business networks by reducing costs, improving efficiencies, and increasing accessibility. It addresses challenges across industries by providing a shared system of record for transactions. The Linux Foundation's Hyperledger project is developing open-source, shared ledger technology standards through collaboration. The blockchain landscape includes identity management, platforms, security, payments, smart contracts, consulting services, industry consortiums, and applications in sectors like finance, supply chain, and government.

This document discusses blockchain and how IBM can help businesses apply it. Blockchain is a shared, replicated, permissioned ledger technology that can improve business networks by reducing costs, increasing efficiencies and accessibility. It addresses challenges across industries. IBM supports the open standard Hyperledger Project and provides blockchain services through Bluemix to help customers get started incrementally with blockchain.

The document discusses integrating IBM Operational Decision Manager (ODM) with blockchain and smart contracts to enable rule-based smart contracts. It provides examples of how ODM can be used to author, govern, and execute the business logic and rules that define smart contract terms and conditions. Key points include externalizing smart contract business logic in ODM for maintenance by business users, and integrating an ODM rule execution server with Hyperledger Fabric to allow calling decision services from smart contracts via REST APIs. This enables evolving smart contracts governed by business users without changing code.

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.

Blockchain technology allows strangers on the internet to agree on transactions without a central authority through the use of distributed ledgers, consensus algorithms, and cryptography. The Hyperledger project is developing open source blockchain frameworks and tools for businesses to create applications on permissioned blockchains. An example application tracks pork products in a supply chain using smart contracts on Hyperledger Fabric to provide transparency into where products come from.

The first slide deck from the IBM Blockchain Foundation for Developers course with an introduction to IBM Hyperledger architecture.

This document discusses key concepts and components related to blockchain solutions, including actors such as users, developers, operators, and architects. It describes various components that make up blockchain solutions such as ledgers, smart contracts, consensus mechanisms, and how applications interact with blockchains. It also covers considerations for blockchain developers and operators, and challenges around integrating blockchains with existing systems and achieving determinism.
