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 provides an overview of blockchain technology and its applications for businesses. It discusses how blockchain can be used to streamline business processes and transactions by establishing trust, accountability, and transparency across business networks. Key points made in the document include: - Blockchain allows for real-time integration of business transactions and makes business activities transparent and auditable. It can eliminate intermediaries and scale easily. - Blockchain opens up new business models by sharing information in a distributed ledger across organizational boundaries. - Examples are given of how blockchain could improve efficiency in areas like trade finance disputes, supply chain management, and more. - The document outlines some of the key components of blockchain solutions like smart contracts, consensus mechanisms, and

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 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.
