Why Backups Are Critical for Crypto Wallets

On 05.02.2026

Crypto-gammon with Bitcoin, which synchronizes with the server and the dark storage system to save and backup data. — Backup is a single way to update access to digital assets

Cryptocurrency is often perceived as a fully digital asset that exists “somewhere on the internet.” Because of this, many users mistakenly believe that access to coins can be easily restored in the same way as a password for email or a social media account. In reality, crypto wallets operate according to a completely different logic. There is no support service that can restore access in case of data loss. That is why backups play a key role in the security of crypto assets and are often the only way to preserve funds.

How Different Browsers Verify SSL Certificates in Different Ways

Three characters in the form of Chrome, Firefox, and Safari browsers are checking an SSL certificate: one examines it through a magnifying glass, the second evaluates it favorably, and the third inspects the document in detail with a flashlight. — Different browser approaches to assessing the security of an encrypted connection

When a user opens a website and sees a padlock icon in the browser, it is perceived as a simple and clear signal of security. However, behind this symbol lies a complex SSL certificate verification mechanism that is triggered every time a secure connection is established. It is important to understand that different browsers may implement this verification differently. While the basic security principles are shared, specific trust policies and responses to errors vary, and this often explains why the same website behaves differently in different browsers.

Why SPF, DKIM, and DMARC Are More Important Than Complex Passwords

When it comes to email security, most users primarily think about complex passwords. Longer ones, with numbers, symbols, and regular changes. This makes sense, because a password protects access to a mailbox. However, in reality, the password is rarely the main cause of email-related problems. Even a perfect password will not prevent attackers from sending emails on behalf of your domain, spoofing the sender, or reducing trust in your entire email infrastructure. This is where SPF, DKIM, and DMARC come to the forefront — technologies without which modern email simply cannot be considered secure.

Why automatic backups are dangerous without control

A man is sleeping at his laptop next to a server with a cloud backup shown above it with a warning sign. — Automatic backups without verification can create a false sense of security

Automatic backups have long become a standard practice for websites, servers, and online services. They create a sense of security: the system copies data on a schedule, the user does not spend time, and there is confidence that in case of problems everything can be quickly restored. The term “backup” itself means a reserve copy of data — a copy of files, databases, or settings that is stored separately from the main system. However, automation often creates the illusion of complete protection, while in practice, without control, such backups can become a source of serious risks.

Telegram implements modern account protection mechanisms

Over the past few years, Telegram has evolved from a simple messenger into a full-fledged platform for communication, work, business, and information sharing. It stores personal conversations, work chats, financial agreements, access to services, and even elements of users’ digital identity. That is why account security has become critically important. The latest Telegram update, which allows users to log in without passwords and SMS codes, is a logical step toward modern digital security.

Why It’s Important to Protect Not Only the Website but Also DNS Records

Website security is traditionally associated with protection from hacks, viruses, or DDoS attacks, but in reality, there is another critically important element that even experienced website owners often overlook. This refers to DNS records — the fundamental mechanism that ensures users land on your legitimate website rather than a malicious copy created by attackers. DNS, or the Domain Name System, is the system that translates human-friendly domain names into technical IP addresses. Essentially, it is the “phone book” of the internet. If DNS works incorrectly or is modified by an unauthorized party, your website may become inaccessible, visitors may be redirected to phishing pages, and domain mail services can become completely blocked. This is why DNS protection is just as important as safeguarding servers or web applications.

What Should Be Rethought After the Cloudflare Outage

Server, smartphone, and computer show errors during cloud infrastructure failure. — Vulnerability of infrastructure on which millions of websites depend

When a small website goes down, it’s a problem only for its owner. But when Cloudflare, one of the largest infrastructure service providers on the internet, goes down, the problem becomes global. The latest outage once again demonstrated that the modern internet depends on Cloudflare far more than it may seem at first glance. Tens of thousands of websites stop loading, some applications behave unpredictably, and even major international platforms fall into digital “darkness.” This is not just a technical incident — it is a reason to reevaluate your architecture and understand how the internet works today.

What can happen if you do not update your security system for years

In the modern world, the issues of cybersecurity and protection of important facilities are extremely urgent. However, many people still treat the updating of security systems lightly — as if “it works, so it’s fine.” Practice shows that a system that has not been updated for years turns into a time bomb. A vivid proof of this is the recent high-profile robbery in one of the most famous museums in the world.

HTTPS as a Factor of Trust and Google Ranking

The Internet today is not just a network of websites — it’s an entire ecosystem where security, trust, and user convenience have become key indicators of quality. One of the most visible elements of this security is HTTPS — a protocol that ensures secure data exchange between the user and the website. If in the past HTTPS was associated exclusively with banking services or online stores, now it has become the standard for any modern website. Google has long established that the presence of an SSL certificate — which enables HTTPS — affects not only user safety but also a website’s position in search results.

How to Use ChatGPT Safely and Verify the Information You Receive

ChatGPT is a powerful tool that generates text-based answers from a vast dataset, but it is not a database of facts. It produces plausibly sounding responses (answers that seem convincing and logical, even if they may be inaccurate or fabricated) by relying on language patterns. This means that even when answers sound confident, they may still be false or incomplete. Reviews show that the model can make mistakes in simple questions and continue making them even after corrections. This means its conclusions should be treated as suggestions rather than absolute truth. That is why it is important for users to follow safety rules and verify the information.
