What is blockchain?

Blockchain is a distributed and decentralized database, where data is stored in the form of "blocks" connected to each other to form a chain (the network). There is no central device controlling it; instead, it is operated by a group of different parties around the world, making it highly secure and trustworthy.

How does it work?

- Transactions or data are recorded in new blocks, and these blocks need to be verified by the parties in the network before being added to the chain.

- After verification, the block is linked to previous blocks using encryption techniques, making it very difficult to change any data in a previous block.

- Each party in the network holds a copy of the entire database, ensuring transparency and continuity even if some parties are disconnected.

Common uses

- Digital currencies like Bitcoin and the developments based on them.

- Recording financial and legal transactions.

- Managing supply chains and ensuring the authenticity of products.

- Applications in financial and health services and others that require data reliability.
