Lo dice el título. Si quiers saber qué es blockchain, cómo fuciona, qué valor aporta al mundo empresarial y por qué estamos todos buscando un posicionamiento claro, te lo cuento en 10 transparencias.

i) An expanding-only set of cryptographically signed irrevocable transactional
records shared by all participants in a network
(ii) A decentralized record of info (append-only) pre-agreed by the participants
in a network and difficult to tamper with (or retrospectively change)
What is Blockchain?
Just a technology
Cryptography-based
Both to secure
identities for signing
transactions and
ensure nobody can
change the history
Timestamped
All the stored
information is recorded
including timestamps of
when that info was
recorded
Enterily decentralised
There as many copies of
the recorded information
as members in the
network, avoiding any
single or central point
and becoimng
administrator-free
networks
Consensus
Before record any
transaction, a
confirmation and pre-
agreement from the
majority of the
participants is required

PUBLIC USE
Transparency
Every participant knows
what’s happening in the
network. Once info is
recorded anyone can verify it
Immutability
Massive replication of
information cryptographically
signed and recorded makes
extremely difficult to
retrospectively change
Self-audited
Decentralization plus consensus
about the transaction to be
recorded removes the need of
central authorities that certifies
TRUST
We create Trusted
ecosystems where I can trust
anyone being part of it even if
I don’t know or trust her in a
bilateral relationship
Beyond technology, blockchain brings us…
The values of Blockchain

A database ..
What isn’t?
.. to store your own information
securitized because of the use of
cryptography and decentralization

Blockchain is not a unique source of truth
Proof vs. Truth
Blockchain helps in proving that something
was entered on the network by someone at
a certain time, but that is not necessarily the
truth

Actually, I don’t care untamperability, full decentralisation, start
working with 20+ different partners or join a consortium, etc.
I just need to audit & prove easily that something happened without
the need for a trusted 3rd. Party to guarantee it …
… and get benefits from that
Nobody really needs a blockchain for whatever
The harsh reality
• What are the customers doing with Blockchain?
• What are they telling us?
• What technologies are they experimenting with?
• Are they setting-up consortia?
• Have they gone live?
• Are they planning doing in the next months?

Companies are entering Blockchain following the innovation stages
Use cases
Bitcoin &
ICOs
Cryptocurrencies is
the first and
actually unique
success case for
Blockchain
Proof of X
Get Benefit from
immutability to
demonstrate
something
happened
(provenance
certification,
education, legal
files, etc.)
,
Smart
Contracts
Add programmable
business rules that
acts as triggers to
take actions (SLAs,
insurances,
result-driven funds,
etc.)
Assets
Management
Create a digital
asset and related
transacctions that
register atributes
updates like owner
or location (Supply
chain, logistics,
food traceability,
etc.)
Tokenization
Create digital
representations of
anything valuable
(phisical godos,
fine arts, legal or
ownership rights)
that can be divided
infinitely and
transmitted with
customized rules.

We can’t even
imagine how
blockchain can

we do business

By 2021, 90% of current enterprise blockchain
platform implementations will require replacement
within 18 months to remain competitive, secure and
avoid obsolescence, according to Gartner, Inc.
