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.

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.

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.

Does The Hyperledger Project have the potential to become the engine behind most successful decentralized applications and organizations created in the next 25-50 years? Absolutely! A much better question is how, and in what new ways, can we: a) Build decentralized applications, organizations and APIs at 10x the speed at 1/10 the cost. b) Build situational awareness in the local community. I believe that the convergence of decentralized applications, decentralized organizations, artificial intelligence and IoT brings upon us the Great Displacement of the 21st century, where the majority of workforce will be left without “conventional” jobs, forced to learn new skills and professions. Why? Founders of this group believe that the Hyperledger Foundation will be the engine behind decentralization of the world, a massive economic change of the next 25-50 years. So.... why don't we standardize and democratize the field with and around Hyperledger? What? We are a local micro community of those interested in advancing their knowledge of Hyperledger, its use cases and applications. How? Join our group for a regular dose of human interaction, conversations, smiles, food and drinks on all things Hyperledger: • Use Cases • Competitive analysis of Hyperledger startups (Distributed Apps from disruptive companies in specific vertical markets) • How-To’s • Interviews with individuals working at the edge of the Hyperledger project • Reviews of tools, services and APIs offered by the Hyperledger ecosystem • Best Practices in Application Architecture • Do’s and Don’ts • Application Templates • Hackathons • Security in the decentralized world - on the edge, on the node, in the cloud and in transit • How others solve some of the hard problems that exist in the world using Hyperledger. https://www.hyperledger.org https://github.com/hyperledger Join the movement. Let’s change the world. Because with Hyperledger we can. This slides belong to a presentation done by Manuel Garcia @ http://www.meetup.com/HyperLedger-and-Blockchain-Apps-Buenos-Aires

Trading derivatives on a decentralized system aims for high availability (HA) and disaster recovery (DR). Both HA and DR can be met by incorporating a blockchain and a container technology. The Hyperledger is a blockchain framework aims for a cross-industry open standard with the freely customizable plugins, smart contract, and the data payload. Those features exposes us the easy ways to implement our trading platform on a blockchain. The Docker was brought to handle each specific Hyperledger chain internally. Also, hovering the whole Hyperledger nodes with containers reduce our time in building infrastructure, and much easier to be deployed on the production environment. This presentation will show how we integrate the Hyperledger and the Docker container for our derivatives trading project, and the issues that we are focusing on. Additionally, the talk partially includes the performance evaluation results under different configurations. This talk was delivered at LinuxCon Japan 2016 by Siriwat Kasamwattanarote, Thierry Gibralta, Vsevolod Yugov, Shibo Lin, Hideaki Takei, and Fernando Vazquez

This document outlines steps for completing two Hyperledger Composer workshops on deploying and testing sample business networks. The first lab guides users through deploying an existing car auction sample network on the Composer playground and testing basic transactions. The second lab instructs users to create their own business network by defining assets, participants and transactions.

This document discusses how blockchain technology can be used to improve the car leasing business network. It describes the current inefficient system where each participant maintains their own private ledgers, leading to slow, error-prone synchronization. Blockchain allows for a shared, distributed ledger that gives all participants visibility into the single system of record. This increases trust, reduces costs and risks compared to the current methods. Specific benefits highlighted include improved traceability, more efficient auditing and regulatory compliance, and near real-time execution of transactions like letters of credit.
