What is blockchain?


What is Blockchain?• “The blockchain is an incorruptible digital ledger of

economic transactions that can be programmed to record not just financial transactions but virtually everything of value.”Don & Alex Tapscott, authors Blockchain Revolution (2016)


• Blockchain is a secure, shared, distributed ledger that can be public, private, or consortium

• Secure - Uses cryptography to create transactions that are impervious to fraud and establishes a shared truth.

• Shared - Blockchain value is directly linked to the number of organizations or companies that participate in them. There is huge value for even the fiercest of competitors to participate with each other in these shared database implementations.

• Distributed - There are many replicas of the blockchain database. In fact, the more replicas there are the more authentic it becomes.

• Ledger - The database is append only so it is an immutable record of every transaction that occurs.


What is Blockchain?• It can be perceived as a database problem

• Can databases and blockchain live happily ever after?

• By allowing digital information to be distributed but not copied, blockchain technology created the backbone of a new type of internet.

• Bitcoin has been called “digital gold,”

• To date, the total value of the currency is close to $9 billion US.


• Blockchain was introduced by Bitcoin

• Response by technical community to Wall Street crash

• Decentralized Control• Nobody owns the network

• Immutability• Tamper Resistance

• Create and transfer assets with no reliance on a central entity


How does blockchain work?


• Applications

• Decentralized blockchain computing platforms

• Decentralized processing and storage• Smart Contracts

• Cryptographic primitives, consensus protocols and algorithms


Major attraction• Public Verifiability

• Uncorrupted and unaltered data

• Transparency


Blockchain as a Database is awful• Throughput is a few transactions a second

• Latency before a confirmed write is ten minutes

• Capacity is a few Gb.

• Adding nodes causes more issues

• Double the nodes produces quadruple the network traffic• No improvement in throughput, latency or capacity

• Oh, and you can’t query it very well


Blockchain as a Database is good• Consortium Database

• Decentralized / shared control

• blockchains allow enemies to work together for a common benefit• R3 for banks

• Open Music Initiative

• Immutability and audit trail

• Assets and exchanges


CRUD vs Append Only• User can add more data in the form of blocks

• Read Operations: these query and retrieve data from the blockchain

• Write Operations: these add more data onto the blockchain


Different Types of Blockchain•Permissioned and Private:

• R3 Corda• Hyperledger

•Public Smart Contract• Ethereum

Cryptokitties

Microsoft’s Strategy

Smart Contracts

An Open Cloud

• Microsoft has world class Identity Services through Azure Active Directory

• Our corporate strategy is focused on creating and nurturing an open cloud ecosystem

• We have flexible architecture that allows you to avoid vendor lock-in
