Agenda

Using our engaging learning methodology including a variety of tools, we’ll cover the entire curriculum.

What is Blockchain?

- A record keeping system
- Trust
- Decentralization
- Trustless environment

How does Blockchain work?

- Announcements
- Blocks
- Nodes
- Chaining
- Verification
- Consensus
- Scalability
- Privacy
- Crypto Hashing
- Digital Fingerpring
- PoW vs PoS

Types of Blockchains

- Public vs Private
- Open vs closed
- Smart Contracts
- Blockchain as History
- Tokens / Coins
- Gas

How is Blockchain different from what we have today?

- Decentralized
- Peer-to-peer architecture
- Software vs Firmware
- Database vs Blockchain
- Distributed database or other technology?
- Data Sovereignty
- Group Consensus

What are Use Cases for Blockchain?

- Use Case Examples
 Currency
 Banking Services
 Voting
 Medical Records
 Supply Chain / Value Chain
 Content Distribution
 Verification of Software Updates (cars, planes, trains, etc)
 Law Enforcement
 Title and Ownership Records
 Social Media and Online Credibility
 Fractional asset ownership
 Cable Television billing
- High fault tolerance
- DDoS-proof
- Public or Private Blockchain?
- Who are the participants?

What does a Blockchain app look like?

- DApp
- Resembles typical full stack web application
- Any internal state changes and all transactions are written to the blockchain
- Node.js
- IDE
- Public Blockchain visibility
- Private Blockchain solutions
- Oracles

How do I design a Blockchain app?

- What does this solution need to let users do?
- Will the proposed solution reduce or remove the problems and pain points currently felt by users?
- What should this solution prevent users from doing?
- Do you need a solution ready for heavy use on day 1?
- Is your solution idea enhanced by the use of Blockchain? Does the use of Blockchain create a better end-user experience? If so, how?
- Has your business developed custom software solutions before?
- What level of support are you going to need?
- How big is the developer community?
- Does your vision of the future align with the project or platform's vision of the future?
- Does the platform aim to make new and significant contributions to the development space, or is it an efficiency / cost play?
- Should the solution be a public or private Blockchain?
- Should the solution be an open or closed Blockchain?
- Create a plan for contract updates and changes!
- Hybrid solutions
- Monetary exchanges?

How do I develop a Blockchain app?

- AGILE approach pre-release
- Define guiding principles up front
- Software vs Firmware
- Announcements, not transactions!
- Classes, not contracts
- Link contracts to share functions
- Use calling contracts to keep contract address the same
- Hyperledger vs Ethereum
- CONSIDER No of Users * Avg No of Transactions (state changes) per User

Should a Blockless solution be applied?

- Performance
- Security
- Anonymity
- Security
- Monolithic vs Modular
- Sandwich complexity model

How do I test a Blockchain app?

- Recommend 5x to 10x traditional application testing time
- SECURITY is #1!
- Networks (Ethereum)
