Explain the value of a business network
A business network is a complex network of companies working together to accomplish
a certain objective
Business networks benefit from connectivity and data transparency
Participants are customers, suppliers, partners and can be cross-geography
Business networks enable streamlined business processes and allow companies to
focus on their specialties
Articulate Blockchain for business concepts
Smart Contract - A set of code-based workflows that are predetermined by two
counterparties that can automatically set deal terms based on various thresholds
Public Blockchain
Private Blockchain
Permissioned Blockchain
Consortium
,Articulate the differences between blockchain for business and other blockchain
Because of privacy issues present in a business environment. A company may elect to
implement a private or permissioned blockchain, rather than a public blockchain (i.e.
BTC)
Companies can configure the consensus mechanism, assets being transferred, or what
data gets written to the blockchain and assign permissions to network admins
Requirements of a blockchain for business
Assets: Participants decide which assets to share Identity: Participants now who they
are dealing with; information shared is need-to-know
Endorsement: Participants give provable endorsements
Demonstrate an understanding of the key stakeholders in a blockchain solution
Outline the Hyperledger projects and goals
Burrow - Permission able smart contract machine (EVM)
Fabric - Permissioned with channel support
Indy - Decentralized Identity
Iroha - Mobile application focus
Sawtooth - Permissioned & permission less support; EVM transaction family
Caliper - Blockchain framework benchmark platform
Cello - As-a-service deployment
Composer - Model and build blockchain networks
Explorer - View and explore data on the blockchain
Quilt - Ledger interoperability
Outline what is Hyperledger Fabric
, Open source enterprise-grade permissioned distributed ledger technology platform,
designed for use in enterprise contexts, that delivers some key differentiating
capabilities over other popular distributed ledger or blockchain platforms.
Pluggable consensus protocols enable the platform to be more effectively customized to
fit particular use cases and trust models
No native cryptocurrency required
Outline what is Hyperledger Composer
An open development tool set and framework to make developing blockchain
applications easier
Main goal is to make it easier to integrate blockchain applications with existing business
systems, and thus accelerate time-to-value
Composer also enables users to quickly model an existing business network and
integrate existing systems and data with blockchain applications.
Design a blockchain solution architecture
Explain the lifecycle of a transaction
1. The client creates a transaction and sends it to endorsing peers of its choice
2. The endorsing peer simulates a transaction and produces an endorsement signature
3. The submitting client collects an endorsement for a transaction and broadcasts it
through an ordering service
