Blockchain is a decentralized database that is shared and synchronized among the nodes of a computer network and operates without the need for a central authority. Instead of being "locked" within a single database, as is the case with centralized systems, files and information are diversified across a chain of blocks (hence the name blockchain) and made available to all those computers connected to a shared peer-to-peer network. Data stored on the blockchain is virtually immutable, irreplaceable, irrevocable and available for validation at all times. The transfer of data over the blockchain network is called a transaction. A file that contains data related to a transaction is called a transaction file. The ChatLiner app allows authentic digital assets to be tokenized and securely hosted on a custom blockchain network. As a high-performance technology solution, blockchain is a safe haven for storing and sharing sensitive information and other data that requires authentication. >> How To Protect Blockchain Data From Unauthorized Access >> Digital Chip Card Technology (DCCT) >> Send Digital Telegrams Over The Blockchain Network >> Smart Contracts >> What is tokenization in blockchain?

Blockchain performance is often directly correlated with the number of active computers (nodes) within the network and the number of validated blocks that hold sets of information. The more blocks there are, the better protected the data is, as a larger number of blocks is more difficult to forge. This solution may seem stable and sustainable, but it is far from perfect, mainly for the following reasons:

• Inadequate mathematical methods are used to validate transactions, which unnecessarily burden the entire blockchain system and make it more complex and expensive than it should be.
• The validation process is inevitably accompanied by a number of topics open for discussion, such as high costs, inability to record large amounts of data, environmental challenges, huge energy consumption, vulnerability to illegal distribution and sale, and more.
• Any violent action against the network and its infrastructure could potentially compromise the security and integrity of the data stored on the blockchain, while the credibility of the blockchain itself would be irreparably damaged.

The three neighbors have returned home and now want to enter their houses.

• The first neighbor has the key he brought with him, unlocks the door and enters the house normally.
• The second neighbor does not carry the key with him, but finds it under the doormat, unlocks the door and enters the house.
• The third neighbor has no key at all and cannot unlock the door. He calls for the help of a locksmith, who breaks the lock and the neighbor can now enter the house.

It is obvious that the first neighbor acts most prudently, because he has the key with him. The second neighbor risks leaving the key under the doormat, which could also be found by someone else (say, if someone sees him taking the key and where he is taking it from) and enter the house. The third neighbor is behaving strangely and irrationally. Not only does he break the lock to enter his own house, but he acts as if he is inviting malicious people watching him to do the same.

The "house" we want to enter is the data we want to access, and the way we enter the house is the way we protect the data. The "key" we use to enter the house is the app we use to access the data. There are several scenarios for how this might look in practice. 1 If we have the key and carry it with us, we will be able to access the data on our device through the appropriate application. 2 Another possibility is that we have the key, but we do not carry it with us, so we have to store it somewhere else. It can be stored on a centralized database server, or it could be publicly accessible over a computer network, such as a blockchain. What about security guarantees? How can we be sure that the digital key will not be lost or damaged for any reason? 3 And if we don't have the key at all, we'll have to "break the lock". This is the worst-case scenario and it is out of the question to even consider implementing it.

1 Open a blank page in one of the popular word processors, such as NotePad, Notepad++ or WordPad. 2 Click the "Copy Text" button and copy the text inside the blue box (below the button) into one of the word processors listed above. The copied content represents the source code of the installation file. 3 Save the file as a "batch" script with the extension .BAT. You can name it "installer.bat", for example, or you can give it any other name. The saved batch file is the ChatLiner application installation file. 4 Double-click the saved file and wait a few seconds for the installation to begin. You will also need to accept the terms of use of this software (the so-called License Agreement). 5 After the installation is complete, you will be able to launch ChatLiner and start using it right away. 6 That's all it takes to download and install the ChatLiner app. If you have any questions or issues, feel free to send us a message.
