A blockchain is a distributed, immutable database
where information is stored in blocks that are
cryptographically interconnected. Each block contains a
set of transactions, as well as a link to the previous
block. This creates a chain of blocks that is constantly
growing and updating.
Key characteristics of the blockchain:
Decentralization
Transparency
Immutability
Сryptographic protection
Resistance to failures

The principle of operation of the
blockchain:
1) Transaction: The user initiates a
transaction, for example, sending
cryptocurrency to another user.
2) Verification: The transaction is verified
by nodes (computers) on the network.
3) Block: After the transaction is
confirmed, it is combined with other
transactions and recorded in a new
block.
4) Adding to the chain: A new block is
added to the block chain after
confirmation by the network nodes.
5) Dissemination: New information is
distributed throughout the network,
updating copies of the blockchain from
all participants.

Is it advisable to use blockchain technology in the
Electronic Department information system?
Blockchain technology, despite its
reliability, is not suitable for the
Electronic Department information
system due to the complexity,
redundancy and high costs of
implementation and maintenance. It
is better to use it in financial systems
with high security requirements and a
large amount of data, for example, in
banks and exchanges.
