When entering a virtual world, people often do not appear as they do in real life. They may use a different avatar, a different name, or a way of expressing themselves that is entirely different from what is familiar in everyday life. This change opens up many opportunities for communication, creativity, and self-exploration. However, it […]

In discussions about virtual worlds, people often focus on vivid visuals, virtual reality devices, or the ability to interact with others. However, behind all these experiences lies a more fundamental question: who is a user really in the digital space? This question concerns more than an account name or avatar. It includes interaction history, friend […]

When quantum technology is mentioned, many people immediately think of quantum computers and the problems that conventional computers struggle to handle. But another area of development is also attracting considerable attention: quantum sensors. Rather than using qubits to perform algorithms, quantum sensors harness the principles of quantum mechanics to observe and measure the world with […]

Among the applications commonly mentioned when discussing quantum computers, molecular and materials simulation holds a special position. This is not merely a problem chosen to illustrate the power of a new technology; it is also directly connected to chemistry, pharmaceuticals, energy, and materials science. The reason is that molecular systems inherently follow the laws of […]

Why is CPU cooling an important part of a computer? A CPU performs millions of calculations in a very short time, so it constantly generates heat during operation. When running light tasks, this amount of heat is usually not a major problem. However, when editing video, playing games, processing data, running virtual machines, or using […]

In a computer, the power supply is often the least-noticed component. Users tend to focus on the processor, graphics card, memory capacity, or storage speed, while treating the power supply as a component that only needs to provide sufficient wattage to be installed. This approach can lead to a system that operates unreliably, is difficult […]

In the cryptocurrency ecosystem, the phrase “not your keys, not your coins” is often mentioned when discussing control over assets. The idea behind it is quite simple: if digital currency is held on an intermediary platform, users do not directly possess the private keys needed to approve transactions. By contrast, when using a self-custody wallet, […]

In the digital asset market, the phrase “not your keys, not your money” is often used to emphasize the value of control. Behind that saying lies an important choice: entrusting assets to a custodial platform or self-custodying the information that allows access to those assets. These two approaches differ not only in their user interfaces, […]

For many years, passwords have been the most familiar layer of protection for online accounts. Users create a string of characters, memorize or save it, and then enter it whenever they log in. This approach is simple, but it is increasingly revealing numerous weaknesses: passwords can be guessed, exposed in a data breach, stolen through […]

In the early stages of generative AI, much of the conversation revolved around the ability to write and answer questions using text. However, the data people use in their daily work is not limited to words. A meeting may be stored as an audio recording, a report may contain tables of figures and charts, while […]

For many years, passwords have been regarded as the basic layer of protection for most online accounts. Users have been advised to create long passwords, avoid reusing them across services, and change them when there are signs of unusual activity. However, these requirements also create a paradox: the more secure a password is, the harder […]

From Sending to Completion When a user clicks the button to send assets in a blockchain application, the transaction does not immediately become an immutable line of data in the ledger. The action first creates a message containing the necessary information, such as the sender’s address, the recipient’s address, the type of asset, the amount, […]
