• Blocks and Chains

• Encryption

• Distributed Ledger Technology

• Consistency and Consensus

• Centralized and Decentralized

• Azure Blockchain as a Service (BaaS)

• BaaS and SaaS Integration

• Cloud stack demo and sample code


Why Azure?

• Multi-cloud World• Speed to POC• Machine Learning• AI• Data science• CosmosDB


Azure Blockchain as a Service

(BaaS)

Blocks

• As transactions happen they are gathered into a block.

• When there are enough transactions the block is prepared for consensus and eventually attached to the chain.

• Hashing provides a checksum of the data

Blockchains: A continuously growing list

of blocks (records)

• Blocks are chained together using cryptographic hash of the previous block

• Supports decentralized and distributed solutions

• Once a block is attached to a chain the records become immutable.

• You can track transactions on blocks back to a point in time

blocks and chains

Modern Data

• RDMS: SQL Server (pages)

• NoSQL: Cosmos DB (documents)

• Graph DB: Cosmos DB (nodes)

• Distributed Ledger (blockchain, IOTA, Tangle)

• Can be distributed on a decentralized network and is never ending

Data Consistency Models

• ACID: Atomic, consistent, isolated, durable

• BASE: Basic Availability, Soft-state, Eventual consistency

• SALT: A mix of ACID and BASE

• Sequential , Agreed, Ledgered , Tamper-resistant

C o n s i s t e n c y

• Consensus provides consistency

• Consensus you work with today

• AD, SQL Clusters, Global Exchange Mailboxes

• Consensus in blockchain

• 45+ Algorithms

Centralized Cloud Model

• Azure Credits

• AWS Fees

• Google Fees

Decentralized Apps Model

• Gas (ETH, others)• Utility coins

CentralizedAnd

Decentralized


T H R E E T Y P E S O F D E C E N T R A L I Z AT I O N

Architectural (de)centralization• how many physical computers is a system made up of? • How many of those computers can it tolerate breaking down at any single time?

Political (de)centralization• How many individuals or organizations ultimately control the computers that the

system is made up of?

Logical (de)centralization• Does the interface and data structures that the system presents and maintains look

more like a single monolithic object, or an amorphous swarm?

• One simple heuristic is: if you cut the system in half, including both providers and users, will both halves continue to fully operate as independent units?

PUBLIC CONSORTIUMSPRIVATE

T H R E E T Y P E S O F B L O C K C H A I N N E T W O R K S

“Public blockchains provide a way to protect the users of an application from

the developers, establishing that there are certain things that even the

developers of an application have no authority to do.” -Vitalik Buterin
