Blockchain is a distributed, secure digital ledger technology used to record transactions and information. It consists of a series of "blocks" that are strung together and encrypted to ensure the integrity and immutability of data. It achieves its meaning through distribution, security, transparency, automation, decentralization and high efficiency.
What is blockchain?
Blockchain is a distributed, secure digital ledger technology used to record transactions and information. It consists of a series of data structures called "blocks" that are strung together and encrypted to form an unchangeable record.
Meaning of Blockchain
The main meanings of Blockchain are as follows:
-
Distributed: Blockchain data is stored on multiple computers connected in a network rather than controlled by a single entity.
-
Security: Blockchain uses encryption and consensus mechanisms to ensure the security of transactions, making unauthorized changes nearly impossible.
-
Transparency: All transactions are recorded on the blockchain and available for public review, increasing transparency and accountability.
-
Immutable: Once a transaction is recorded on the blockchain, it is nearly impossible to modify or delete, ensuring data integrity.
-
Automation: Blockchain automates many tasks traditionally performed by intermediaries, such as verifying transactions and settlement.
-
Decentralization: There is no central authority controlling the blockchain, but it is jointly maintained by participants in the network.
-
Efficiency: Blockchain increases efficiency by eliminating middlemen and automating processes.
