This is a session dedicated to blockchain. We will talk about mining inside a cloud provider and why blockchain is so attractive to any company nowadays. In the second part of the session we will talk about a new service from Azure that is allowing us to use blockchain as a service (SaaS)

2. Why near-real time?

3. What is cryptocurrency?

4. Limited entries in a database no one can change
without fulfilling specific conditions

USP
Disruptive
Disruptive in the sense of
disintermediation. No middle men
needed. Unclear what the business
models will be.
Cost Cutting
Can radically reduce transactions
costs. Similar to SAP in the 1990s.
Extreme cost cutting opportunities.
Less data redundancy, higher
transactions times, more transparency
