What are the main features of blockchain technology?

Blockchain technology is evaluated as one of the core technologies of the 4th industrial revolution era, and has a structure that can simultaneously enhance security, transparency, and efficiency in transaction and data management processes.

First, blockchain is based on distributed ledger technology, which means a structure where all network participants can share and verify the same transaction records.

Since transaction records are stored simultaneously across multiple participants rather than being concentrated on a central server, this approach helps reduce duplication in data processing and maintain consistency of records.

Additionally, blockchain has an immutable record structure where content recorded once cannot be easily changed or deleted.

Even if errors occur, they are processed by adding new transactions rather than modifying existing records, so all history remains intact, ensuring transparency.

Smart contract functionality is also one of the important elements. This is a contract designed to be automatically executed when certain conditions are met, reducing intermediation processes and increasing transaction speed and efficiency.

Finally, public key cryptography is a core technology that protects data and assets, allowing safe management of transaction approval and ownership through public and private keys.

As such, blockchain technology combines various security and operational structures to enhance the trustworthiness of the entire environment.
