Curiosities About Blockchain Technology
With the rapid increase in the place of technology in our lives, the need for information and data security is also increasing rapidly. Especially in areas such as finance, where personal data is included and many transactions are carried out together, this need is much greater. This is where blockchain technology comes into play, aiming to ensure data security and transparency. So, what is blockchain? What is blockchain technology? Let’s examine the answers to these questions and more together.
What is Blockchain?
Blockchain defines the chain structure consisting of blocks. Blockchain provides the tracking of encrypted transactions as a distributed database system. Blockchain facilitates processes such as recording transactions and tracking assets in the business network. At the same time, this system can also be thought of as a ledger that can be shared and cannot be modified.
Blockchain is a shared and unalterable ledger that facilitates the process of recording transactions and tracking assets in a business network. Assets can be tangible (house, car, cash, land) or intangible (intellectual property, patents, copyrights, trademarks). Almost anything of value can be tracked and transacted on a blockchain network, reducing risk and lowering all costs involved.
The importance of blockchain
Business runs on knowledge. The faster and more accurate the information, the better. Blockchain is ideal for the delivery of information because it provides instant, shared and fully transparent information stored on a large ledger that can only be accessed and modified by network members with permission. A blockchain network can track orders, payments, accounts, production and much more. Because members share a single view of the truth, you can see all the details of a transaction from start to finish, leading to new efficiencies and opportunities, as well as greater trust.
Why Blockchain Technology Matters
For business processes to function safely and efficiently, information needs to be transferred in the fastest and most accurate way possible. The main benefit of blockchain at this point is that it is a ledger that only authorized network members can access. Moreover, members who can access the system cannot make any changes to the data. Another feature that makes blockchain ideal is that it is a structure that can be shared and provides transparent information. This is reassuring for the user.
How Does Blockchain Work?
Blockchain does not have a centralized system. Access to the data in the blockchain can be provided through all computers. In addition to accessing the information, it is possible to transparently access information such as who the transactions made here belong to and when they were made.
Since the transactions made in this technology cannot be changed, a new record is added to the system when a correction is desired. Thus, all details are preserved, and all correct and incorrect transactions can be observed.
In blockchain technology, identity is created in the form of a user identification number that is recognized by all networks. Thus, instead of using personal information such as username and surname, all transactions are made with this ID number. The transactions made here are encrypted with mathematical calculations in the user’s system, i.e., hash functions, and recorded on the chain.
The character strings created with hash functions consist of letters and numbers. In case of the slightest change, a different string is created.
All transactions are verified by the user and the records become permanent. This shows that this technology is not centralized. In short, what makes blockchain technology important is that it has an anonymous structure, it is not a centralized system, and it cannot be corrupted or hacked.
The Basic Elements of a Blockchain
Distributed ledger technology
All network participants have access to the distributed ledger and transaction records, which cannot be modified. With this shared ledger, transactions are recorded only once, eliminating the repetition that is common in traditional business networks.
Non-modifiable records
Once a transaction is recorded in the shared ledger, it cannot be modified or tampered with by any participant. If a transaction record contains an error, a new transaction must be added to reverse the error and both transactions will be visible.
Smart contracts
To speed up transactions, a set of rules, called a smart contract, is stored in the blockchain and these are automatically executed. A smart contract can define conditions for corporate bond transfers, conditions for travel insurance to be paid, and more.
What Does Blockchain Technology Do?
Blockchain technology offers data privacy with its ability to store information securely. To change the data contained here, you need to get approval from other blocks. This activates the approval mechanism as many as the number of blocks. Thus, the system ensures that the data is secure by preventing any good or malicious action that may come from outside.

What are the Uses of Blockchain?
Blockchain technology has a structure and function that can be used in many different sectors. Here are the main sectors where this technology is widely used:
- Public sector
- Finance sector
- Energy sector
- Health sector
- Supply chain
Types of blockchain networks.
- Public blockchain networks
- Private blockchain networks
- Permissioned blockchain network
- Consortium blockchains
How does a cryptocurrency database work?
Blockchain technology enables these functions on networks to be performed in a decentralized manner and at lower costs. Blockchain is a database system consisting of interconnected blocks. Any information involving a transaction can be entered into this database. New transactions are added on top of the previous block and a new block is created. These blocks are connected to each other chronologically. In this way, the new block verifies the information in the previous blocks and increases the security of the records. Everyone on these blocks is encrypted and therefore has a distributed structure. Therefore, it becomes almost impossible for one person to change the past records on this network, as this would require changing the records on other users. The larger the network, the more separate records there are, the more secure it becomes. This eliminates the costs of verification and auditing mentioned above and provides an accountable and reliable structure.
To put it more simply, let’s think of the blocks on a blockchain as a ledger. Copies of these ledgers are distributed to everyone on the network. Every new transaction is written to these ledgers simultaneously, so that records of transactions are kept in many places, not just one or a few. Since there is only one record in a centralized structure, securing these records is a significant cost. However, in a decentralized blockchain structure, it is not possible to change all records, thus creating a more secure system.
In a centralized system, the privacy risk posed by the data that intermediaries need to access when making transactions is another cost of this structure. Transactions made through an intermediary often need to be shared due to the verification process. This increases the possibility of data being used in the network for purposes other than its original purpose. In addition, the security of the data kept on the intermediary institution that manages the network is another problem and cost. In blockchain, such information leaks are prevented as users can verify without sharing information with another person or organization.
Blockchain technology has the potential to change the processes carried out over networks in many different sectors and fields such as finance, health, science, and industry. This potential excites all organizations in the relevant sectors and investments in blockchain technology are increasing day by day for these reasons.
