Blockchain is a distributed ledger used to record network transactions and link them into an immutable chain. Key features include: immutability, decentralization, transparency and security. It is widely used in fields such as finance, supply chain management, healthcare, government, and entertainment.

What is blockchain?
Blockchain is a distributed ledger technology that records transactions that occur on a computer network. These transactions are called blocks and are linked together to form an immutable chain, hence the name "blockchain".
How does blockchain work?
-
Transaction initialization: When a transaction occurs, it will be put into a transaction pool.
-
Block Creation: Miners collect transactions from the transaction pool into a block.
-
Block Verification: Miners verify blocks by solving complex mathematical problems.
-
Block Linking: Verified blocks are added to the blockchain, linked with the previous block.
-
Distributed Storage: Copies of the blockchain are stored on multiple nodes in the network.
Main Features of Blockchain:
-
Immutable: Once added to the blockchain, blocks cannot be deleted or changed, ensuring data integrity.
-
Decentralization: The blockchain is maintained by multiple nodes in the network rather than by one central authority.
-
Transparency: All transactions on the blockchain are open and transparent and can be viewed by anyone.
-
Security: The distributed nature and verification mechanism of blockchain make it highly secure.
Applications of blockchain:
Blockchain technology has a wide range of applications in various industries, including:
-
Finance: Cryptocurrency, digital payments and settlements
-
Supply chain management: Item tracking, inventory control and anti-counterfeiting
-
Healthcare: Medical record management, patient data verification and clinical trial tracking
-
Government: Elections, property registration and identity verification
-
Entertainment: Digital content copyright protection, content Distribution and fan engagement
