How blockchain technology is changing the
security landscape
Blockchain technology act as a database which is
required to store information in a digital
format. It is a digital ledger system which is
required to share documents within the computer
system. This technology is also used for
maintaining a secure and decentralized process
for recording transactions and information
without the interference of third parties.
Blockchain is a secure system of storing data
used by companies. You can also read Best data

Blockchain working Mechanism
This technology collects data into blocks and
then links them together such that each block
reaches its maximum capacity. The linear chain of
information and data formed after the linkage of
blocks is called Blockchain. The data stored in
these chains of blocks is irreversible and
permanently recorded and stored in this
technology. This mechanism plays a vital role in
cryptocurrency transactions and exchanges. Data
that is stored and recorded in the database
system can't be altered or deleted. Blockchain
technology has the same mechanisms in business
structures. Take the example of the insurance
company which records client-sensitive data and
transactions and other third-party sensitive
pieces of information. All the information is
stored on the network of the company and is
backed up on the cloud. In case of hacking and
leakage of sensitive information, Blockchain
technology provides security to the companys
data system. This companys data will be
recovered and secured.

provides all the security to a companys data
system and works in a transparent manner. Data
stored and recorded in blockchain technology is
traceable in real time. The most relevant
example is when hackers hack the exchange wallets
of cryptocurrency. Bitcoin trail is traceable
and easily recoverable. Security Blockchain
technology is designed for the purpose of
providing digital security. Blockchain consists
of a block which is containing a hash that is an
individual cryptographic print. Once blocks are
linked in the blockchain system then it is
impossible to alter any information on the
specific block. The only process of altering the
node on the chain is changing the nodes hash and
that will cause misalignment with other nodes on
the chain. The other nodes will recognize this
practice as it will be considered as the
consensus protocol. The block alignment can be
the case in a case when the hacker is successful
in changing half of the block alignment on the
chain which will be time-consuming and
expensive. You can also read Best data science

• Benefits of Using Blockchain
• Authentication of software Interactions
• Organizations and companies have used blockchain
  hashing to verify updates and downloads from
  developers. This hashing also helps in mitigating
  the supply chain management system.
• Data Integrity
• The data stored on the blockchain system cant be
  altered. This function is significant to
  cross-border data distribution systems. In the
  case of medical records and personal information
  data stored in one country can be used in other
  countries.
