Beyond the buzzword, why everyone wants a blockchain? If you are one of those few people who don't know nothing about blockchain yet, try to say blockchain three times in a row and see whats happen...

Potential and Limitations
Reality

Fiction
What will come in a future
Today’s goals

3. Promise
Will Blockchain really change enerything?

4. A new paradigm like some
others before
First of all: What is it?
PRINT
COMBUSTION

INTERNET
Welcome to the era of truth

5. The very beginning: 2008
Satoshi Nakamoto invented bitcoin and the
blockchain.
For the first time in history, his invention made
it possible to send money around the globe
without banks, governments or any other
intermediaries
A trustless environment to trust each other and among businesses.

6. The Basics
Conventional

Distributed
database
Distributed
ledger
Blockchain
No single point
of failure
Timestamping Consensus building

7. Blockchain bring us…
• Data updated near real time
• Information integrity + timestamped
• Data auditability + immutability
• As robust as distributed architectures
• As secure as other cryptographic solutions
• Transparency of transactions

8. But the most important thing is
BLOCKCHAIN solves governance
issues from the technology

9. How it Works?

10. Let’s see it working

11. Ledger: Trusted but verified

15. Asymetric Cryptography + Distributed systems

Transactions -> blocks -> The ChainHow
Recap: What can we do with a blockchain?
We create immutable records that are undoubtable

16. So, we are building
Internet of Trust
+ control
+ transparency
+ trazability
+ simplicity and flexibility
BLOCKCHAIN is not a goal itself, it is a tool that allows us to be better in our business: operating our network
more efficiently, interacting with our suppliers in a safer and more reliable way, being more agile in our
relationship with our customers, offer products in a more individualized way, personalize your experience, etc.

If you need
securely record
data, you can use
a blockchain

26. Reality
Why are we all talking about Blockchain?

72. Fiction
Really?

73. Where we are?

74. We can summarize what we have seen so far:
• Blockchain is a technologically improved
database that enables the Internet of the
truth
• There are a lot of promises about how
blockchain will change everything
• But in the end, the technology is not mature
enough and the only successful use case
is bitcoin and ICOs
SO, IS IT A BIG FICTION?
What’s behind that?

75. Any self-respecting fiction hide some tricks
No use case really need
blockchain, and can be
implemented using other
technologies …
… but using blockchain
allows us to make thinks
easier and/or cheaper
and/or more efficiently
No use case really address
an unattended need …
… but compete with legacy
centralized solutions and
systems whose replacement
is not a priority
We all are dealing with
blockchain in the
innovation context …
… but forgetting that
innovation starts solving a
customer’s need

76. Blockchain is the Holy Grial
Maybe not,
but is the perfect excuse to
redesign how individuals and
companies interacts in the
digital world

77. However …
We really think that
BLOCKCHAIN
can impact
every business

78. By capturing value from 2 main topics
The
TOKEN
Economy
The
Internet
of Trust

79. And developing an
ordered framework
to develop
business valuable
