What is Blockchain Technology and How Does It Work?

Blockchain technology is a concept that has been talked about frequently in recent years and has the potential to revolutionize various sectors. At its core, blockchain is a distributed database that allows information to be stored in a chained structure in blocks. This structure increases the security and transparency of data while eliminating the need for a central authority. Digital identity Blockchain, which can be used in many areas including systems, makes it almost impossible to change or delete data.

The working principle of blockchain technology is quite simple. Each new transaction is added to the chain as a block. This block contains a hash of the previous block, which maintains the integrity of the chain. If the data in a block is changed, the hash of that block changes and becomes incompatible with the rest of the chain. This allows any manipulation attempts to be easily detected. In addition, since every participant in the blockchain network has a copy of the chain, the risk of data being lost or changed at a single point is eliminated.

Basic Steps of Blockchain Technology

1. Starting a Transaction: A user initiates a transaction on the network (for example, a digital authentication request).
2. Verification: The transaction is verified by nodes in the network. This verification is done according to certain rules and algorithms.
3. Creating Blocks: Verified transactions are collected into a block. This block contains the hash of the previous block.
4. Adding to Chain: A new block is added to the blockchain through a process commonly referred to as mining.
5. Distribution: An updated copy of the blockchain is distributed to all participants in the network.

One of the most important advantages of Blockchain technology is that it provides a secure and transparent environment. This feature is especially digital identity systems. In traditional identity systems, storing data in a central database can increase security risks. However, with blockchain, identity information is stored in a distributed manner, eliminating a single point of attack. In addition, users can have greater control over their identity data and monitor how their data is used more transparently.
