2. 2
Blockchain?
▪ Technology behind BITCOIN (2008)
▪ Next Generation Internet, also known as Decentralized Web
▪ It's a shared, trusted, public (and private) ledger of transactions.
▪ Not controlled by centralized authority.
▪ Cryptographically secured from tampering and alteration
"motivation for blockchain"
"NOVEL SOLUTION TO AGE-OLD HUMAN PROBLEM
OF TRUST."

3. 3
Why it is called Blockchain?
▪ The ledger is built using a linked list, or chain of blocks.
▪ Each block contains a certain number of transactions that were validated by the network in a given
timespan.
▪ The crypto-economic rulesets of the blockchain protocol (consensus layer) regulate the behavioral
rulesets
▪ Incentive mechanism of all stakeholders in the network.

4. 4
How Blockchain Works?
1. Alice wants to send
money to Bob
2. Transaction is represented
as a 'BLOCK'
3. Block is
broadcast to
every party in
the network
4. Network
validate the
transaction
and approve if
valid
(consensus)
5. Block can be added to the chain,
immutable and transparent record
6. Money moves from
Alice to Bob
