This document provides an overview of Hyperledger and blockchain technology. It discusses what blockchain and distributed ledger technology are, some benefits of smart contracts such as autonomy, trust, safety and speed. It also describes permissionless versus permissioned blockchains and gives an overview of what Hyperledger is and some of its projects like Fabric, Iroha and Burrow. Components of the Fabric and Iroha ecosystems are outlined. The document concludes by mentioning the author's work developing a proof of concept application for contract management using Hyperledger Fabric and contributions to the Iroha blockchain JavaScript library.

- 1. Hyperledger Enter a decentralized world
- 2. A little bit of myself George Theofilis Blockchain Developer @ Synaphea. Synaphea was an inspiration of mine, with the ambition to make the transition to a decentralized world easier for a business. I am working with DLT authoring smart contracts on Ethereum and Fabric and I am also creating a web based front-end for smart contract application. • 4+ years of experience in software engineering. • Contributor @ iroha-javascript

- 4. What is the Blockchain / DLT? DLT stands for Distributed ledger technology Blockchain allows multiple different parties to securely interact with the same universal source of truth
- 5. Some benefits from Smart Contracts Autоnоmу Trust Safety Speed There’s nо nееd to rely оn a brоkеr, lаwуеr or оthеr іntеrmеdіаrіеѕ to соnfіrm. Inсіdеntаllу, thіѕ аlѕо knосkѕ out thе dаngеr of manipulation bу a thіrd раrtу. Smart contracts ensures that уоur dосumеntѕ аrе encrypted on a ѕhаrеd lеdgеr. There’s nо way ѕоmеоnе саn say thеу lost it. Cryptography, the еnсrурtіоn of wеbѕіtеѕ, kеерѕ уоur dосumеntѕ safe. Thеrе is no hасkіng. In fасt, it would take an abnormally ѕmаrt hасkеr tо сrасk thе code аnd infiltrate. Rather thаn uѕіng сhunkѕ оf tіmе аnd paperwork tо mаnuаllу process dосumеntѕ uѕе a software соdе to аutоmаtе tasks. Bасkuр Accuracy Savings : Imagine іf your bаnk lost уоur ѕаvіngѕ ассоunt. On thе blосkсhаіn network, еасh аnd еvеrу one of уоur frіеndѕ has your bасk. Your documents are duplicated many times. Autоmаtеd contracts аrе not оnlу faster аnd cheaper but аlѕо avoid thе errors thаt соmе frоm mаnuаllу filling оut heaps оf fоrmѕ. Saves you mоnеу ѕіnсе thеу knock оut thе presence оf аn іntеrmеdіаrу. Yоu would, fоr іnѕtаnсе, have to рау a notary to witness уоur transaction. Aссurасу:
- 6. Permissionless vs Permissioned Permissionless or Public blockchain (like Bitcoin or Ethereum) everyone can join the network Permissioned or Private blockchain (like platforms at Hyperledger) requires pre-verification of the participating parties within the network, and these parties are usually known to each other.
- 7. What is Hyperledger? The Hyperledger Project is a collaborative effort created to advance blockchain technology by identifying and addressing important features for a cross-industry open standard for distributed ledgers that can transform the way business transactions are conducted globally. • Permissioned enterprise blockchain • Modular frameworks • Opens source • Blockchain 2.0 (Shared ledger, Permission, Smart Contract, Consensus)

Projects in Hyperledger Indy Iroha BurrowSawtooth Fabric Quilt Explorer CelloComposer Framework Meaningfully differentiated approaches to business blockchain frameworks developed by a growing community of communities Tools Typically build for one framework, and through common license and community of communities approach, ported to other frameworks

- 11. Fabric Ecosystem SDK • Permissioned network • Confidential transactions • No cryptocurrency • Programmable Characteristics Platform for distributed ledger solutions, underpinned by a modular architecture delivering high degrees of confidentiality, resiliency, flexibility and scalability. • Nodes: Client, Peer, Orderers • CA Server Components
- 12. Iroha Ecosystem Iroha SDK • Torii • Network encompasses interaction with the network of peers • Validation classes • Synchronizer • Simulator • Ametsuchi Components Iroha introduces a Byzantine Fault Tolerant consensus algorithm called Sumeragi
- 13. Our work Iroha We have successfully developed a proof of concept application for contract management with the latest version of Fabric. We are the main contributor of JS library of Iroha blockchain, all the source code is written in TS.
