The main difference between blockchain databases and centralized databases is their architecture or how the technologies used in their structure are implemented.

Databases running on the World Wide Web typically use a client-server model in their architecture.

In this structure, a user (client) can change the data stored on the central server using the permissions assigned to his account. By making changes to the original version of the data, each person will only encounter the updated information whenever they have access to the database.

Keep in mind that in such a structure, control of the database will be in the hands of administrators and managers who retain central control by granting access and permissions.

Note that this structure is not at all similar to blockchain.

Within a blockchain database, each member has a maintenance task; Is responsible for calculating and updating new entries. In this structure, all nodes try to make sure that all the results obtained are the same, in which way the nodes establish security within the network.

From the differences between blockchain and traditional databases, blockchains are more suitable systems for storing data to perform certain functions; Centralized databases, on the other hand, are perfectly suited for a variety of other functions.

In the blockchain, members who do not trust each other can share information without the presence and need of central management. In this structure, transactions are processed by a network of users based on a consensus mechanism, which ultimately creates a similar and shared system of database records at the same time.

The value and importance of decentralized control eliminate the risks of centralized control. Note, for example, that in a centrally controlled database, due to the adequate level of access of some users, we may run the risk of data being destroyed or corrupted by these people. This situation makes users more dependent on network administrators.

Of course, it must be said that some managers have gained more trust in this structure. These include banks wherein banks, people’s money stored in private databases has not been stolen by any bank. In doing such things, we logically need to use central control, and the application of central control has become a required specialty.

Of course, providing this central control has not been easy, and banks have been able to prevent the theft of people’s money or assets by hackers or people who intend to harm others; They have to spend billions of dollars.

In this regard, if those central managers whom we have trusted to maintain our confidential information fail to maintain our information and assets, we will suffer the loss.

Record own 

Most centralized databases hold information that has been updated for some time. These structures generally represent a snapshot of the database.

The China Block Database is capable of storing currently verified information and storing information that has already been obtained. Blockchain technology can generate databases that have a history of their own.

Blockchain databases are expanding an archive of their history and providing instantaneous information storage and performance. This is the cost required for forming and immutability of the China Blockchain database. With the operation of this type of database, we are witnessing a great revolution in converting databases into record systems.

Performance

Although blockchains are used as platforms for transactions and systems of stored records, These platforms are much slower than other popular digital payment technologies such as Visa and PayPal.

However, improvements to the blockchain structure have been considered to address this issue; But in general, blockchain operation is done by spending a certain amount of time.

The concept of distributed networks in blockchain technology is that none of the members of this structure share their computing power or combine it with others. Instead, they each serve the network individually and then compare the results of their work with other members of the network until a consensus is reached.

Conversely, centralized databases have been around for decades. Over the years, these databases have Moore’s Law made significant advances

confidentiality

Bitcoin is a type of reading and writing database. This means that anyone can write a new block within the Bitcoin blockchain chain, and anyone can read block information from within this chain.

An authorized blockchain, which is centralized like a database, is in a controlled read and write mode. This means the network or protocol can be configured in this structure ed so that only authorized members can write or read the information in the database.

If confidentiality is our only goal, and in the meantime, having trust is not a very important issue, China Blockchain Database will not have many advantages over Centralized Database.

Hiding information on a blockchain imposes a heavy computational and cryptographic operations burden on network nodes. In this regard, unlimited storage of data in a private database is considered the best way to hide information, in which there is no need to even connect to the network.

Look at all the databases in the “Mission Impossible” action movie series broken by the “Eaton Hunt” character. You can find out the level of confidentiality in private databases.
