Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain.

5. Bitcoin ≠ blockchain
Is an application of
blockchain technology
Is the underlying datastructure,
which can be used for many
things, including cryptocurrencies

6. Bitcoin ecosystem
A public network in which anyone, including a
malicious participant, can participate without
restriction.
Even though it is not organized by a central
authority, it works!

7. Impact of Blockchain on Bitcoin ecosystem
Increased
Bitcoin Value
More Security

8. What is A Blockchain?
A blockchain is a growing list of data blocks that are linked together. A block in a blockchain is
a group or collection of information. The information is added to the block in a blockchain, by
connecting it with other blocks in the chronological order and creating a chain of blocks linked
together.

10. Blochain A Digital Ledger
Cryptographically Secured
Cryptography is utilized for the safety services to make
the ledger tamper-proof
Add-Only
Data must be included in the blockchain with time-
consecutive requests. This property proposes that once
information is added to the blockchain, it becomes
practically impossible to change..
Distributed
The ledger is spread over the entire network, which
makes data alteration next to impossible.
Consensus
This is the most critical element of all, which gives
blockchain the ability to
update the ledger via consensus. This means that the
blockchain has the power
Peer-To-Peer
There are no central authority to manipulate or control
it. All applicants talk to each other directly.

12. Benefits of
blockchain
technology

13. Cutting the middleman
E.g. direct transfer of Bitcoins

14. Building Consensus
After a finite time, all
participants agree on a single
state.
E.g. on who owns how many
Bitcoin.

15. CREATING WITNESSES
If something is published on a
public blockchain, all
participants become
witnesses.
This is used, for example, by
OriginStamp to create a secure
timestamp for documents.

16. Key Features of Blockchain
 Increased Capacity
 Better Security
 Immutability
 Minting
 Decentralized System
 Faster Settlement

17. Conclusion:
Blockchain technology creates a permanent and immutable record
of every transaction. This impenetrable digital ledger makes fraud,
hacking, data theft, and information loss impossible. ... While
blockchain technology has reshaped and decentralized financial
institutions, its application possibilities are far more robust.
