WHAT IS
BLOCKCHAIN
blockchain is a digital technology that uses
a chain of blocks to store transaction
information securely and transparently,
making it nearly impossible to alter or
falsify data.
THE ROLE OF LEDGER
IN BLOCKCHAIN
A ledger in the context of blockchain refers to a distributed
and decentralized digital record of all transactions across
the network. It is a fundamental component of blockchain
technology, where each transaction is recorded as a block
and linked together in a chronological chain. This ledger is
maintained and validated by multiple participants (nodes)
in the network, ensuring transparency, immutability, and
security of the recorded data. As new transactions are
added, the ledger updates and remains consistent across
all nodes in the blockchain network.
BLOCKCHAIN LEDGER
Blockchain is a decentralized system, with data stored
across a network of computers. It ensures data integrity
through cryptographic algorithms, making it nearly
impossible to alter once recorded. Transactions are
transparent and verified through consensus mechanisms.
In contrast, traditional ledgers are centralized, potentially
vulnerable to tampering and reliant on a trusted authority.

TYPES OF BLOCKCHAIN
There are 3 Types of Blockchain
Public Blockchain
Private Blockchain
Consortium Blockchain
Public blockchains are open and permissionless networks
where anyone can participate as a node. They allow
anyone to read, write, and verify transactions. Examples
include Bitcoin and Ethereum. These blockchains offer
high transparency but might have slower transaction
speeds due to their open nature.
PUBLIC BLOCKCHAIN
Private blockchains are permissioned networks where only
selected entities or participants have access to the
blockchain. These entities typically have known identities
and are authorized to participate in the network. Private
blockchains are often used by organizations for internal
purposes and can offer faster transaction speeds and
higher privacy.
PRIVATE BLOCKCHAIN
Consortium blockchains are a hybrid between public
and private blockchains. They are controlled by a group
of pre-selected organizations or nodes, offering a more
decentralized approach than private blockchains while
still maintaining restricted access. Consortium
blockchains are often used in industries where multiple
organizations collaborate on shared processes and
data.
