3. How does a Blockchain Work

4. Benefits of Blockchain
Faster Settlement
Decentralized
Immutable
Shared and DistributedIncrease network capacity
More Secured

5. Centralized vs Decentralized vs
Distributed - An Overview
Centralized – All nodes are
connected to a single authority
Decentralized – No single authority
controls the node, they have
individual entity
Distributed – Every node is
independent and interconnected
with each other

6. Important Blockchain Terms
Hashcash - Hashcash is an example of a POW. Bitcoin uses the hashcash POW function.
Nodes - Nodes are distributed computers in the network that all have a copy of the entire
blockchain.
Address - A bitcoin address is a long string of alphanumeric characters used to send,
receive or hold currency.
Smart Contract - A smart contract is a digital agreement stored on the blockchain that is
unalterable, once signed.
Block - Transactions are combined into single blocks and every 10 minutes, a new block of
about 1MB is size is created.
Mining - Mining means adding transaction records to the blockchain ledger after
confirming the validity of the transactions.

7. Types of Blockchains
Consortium Blockchain
Private Blockchain Public Blockchain
Semi-Private Blockchain

8. Applications of Blockchains

9. Blockchain Explained – In Easy
Terms
A blockchain is a type of database.
Using cryptography to keep exchanges secure, blockchain provides a decentralized
database, or “digital ledger”, of transactions that everyone on the network can see.
 This network is essentially a chain of computers that must all approve an exchange before
it can be verified and recorded.
It is a digital record of transactions. The name comes from its structure, in which individual
records, called blocks, are linked together in single list, called a chain.
Blockchains are used for recording transactions made with cryptocurrencies, such as
Bitcoin, and have many other applications.
