Introduction to Blockchain
Technology

4. 01
Blockchain enables secure recording of
transactions across a network of
workstations/nodes.
Information is shared and replicated across
multiple nodes, making tampering or
alteration virtually impossible.
Decentralized and Distributed Ledger System
02
Decentralized nature eliminates the
need for a central authority.
Blockchain uses cryptography to
secure transactions and ensure
authenticity and integrity.
Advancing Trust and Transparency
03
Transactions are grouped into blocks
linked together in a chronological
chain.
Blockchain finds applications in
cryptocurrency, supply chain
management, and healthcare.
Immutability and Applications
Overview of Blockchain Technology

5. 01
Nodes
Nodes are computers that participate in the
blockchain network.
Nodes maintain copies of the blockchain,
validate and propagate transactions.
Nodes can be full nodes or lightweight
nodes.
02
Transactions
Transactions represent the
transfer of value or information
between parties.
Each transaction is digitally
signed by the sender for
authenticity and integrity.
03
Blocks
Transactions are grouped into blocks.
Each block contains a list of transactions, a
timestamp, a nonce, and the hash of the
previous block.
The hash serves as a unique identifier,
linking each block to its predecessor.
04
Mining
Miners validate and record transactions by
solving complex cryptographic puzzles.
Mining requires significant computational
power and maintains the blockchain's
security.
Miners are rewarded with cryptocurrency
tokens.
