Sub TitleWhat is Blockchain?
Concept, Overview & Types
How do you trade with someone?
How do you trade with someone?
Trusted 3rd party

How do you trade with someone?
✔
Can agree to an arbitrator
Removes the merchant fees
Faster money transfers
✔
Connecting companies: data silos
Out of sync
Need to reconcile
Which stores the correct truth
Connecting companies: “shared service”
Who owns and controls?
Requires trust
Connecting companies: Blockchain shared truth

보안
Uses cryptography
to create transactions
that are impervious
to fraud and
establishes a shared
truth.
공유
The database’s main value
is that it is shared among
separate entities
Blockchain value is directly
linked to the number of
entities that participate in
them.
분산
Many copies of the
database exist and
they are replicas of
each other in relative
time.
원장
The database is
“write once” so it is
an immutable record
of every transaction
that occurs.

Blockchain Success?
Market Challenges
HYPE
Lots of noise in press,
announcements,
reports, etc.
EMBRIONIC
Many offerings are
new or experimental
targeting potential of
great things
IMMATURE
Few seem to moved
beyond Proof of
Concept; too early to
determine business

To Invest or Not to Invest? The Next Internet or a Bubble?
Blockchain 으로 수익을 내려면 ….
확장성
Enterprises need database-like latency
and throughput
데이터보안
Enterprises need richer more flexible
confidentiality models
컨소시엄관리
Enterprises need built-in distributed governance

3 dimensions of Blockchain technologies
Scope• Public (trustless) – Bitcoin, “Alt Coins”, Ethereum
• Private (trusted) – Ethereum, Ripple, MultiChain
• Consortium (semi-trusted)
Consensus• Proof of work (mining) only for trustless environments
• Proof of stake (escrow)
• Proof of identity, vote, burn, and more
Generation• 1.0 / 2.0
