Blockchain: An attempt to explain it in simple terms

Blockchain seems like a strange concept to many, perhaps only for those with an IT background, but it's essentially a special way to store data so that no one can surreptitiously alter or replace it. We'll explain how it works below, and you can also watch the video if you want to delve deeper.

Imagine a long chain of entries, where each new line is tightly linked to the previous one—as if each entry were secured with a "mathematical seal." Change even one character, and it becomes immediately noticeable. This principle underlies the entire mechanism.

Blockchain is based on blocks of data. Each block records an event: a money transfer, a product entry, user information—whatever. Once a block is filled, it is assigned a digital fingerprint—a hash. This fingerprint is unique: the slightest change transforms it into a different one. A new block always contains the hash of the previous one, so these blocks form a single, unbroken chain.

The most important thing is that the blockchain isn't stored on a single server that can be shut down, destroyed, or hacked. Its copies are simultaneously stored on multiple computers—thousands, sometimes millions. When a new block is created, the entire network verifies its authenticity. If the verification is successful, the block is added to all copies. To change history, an attacker would have to hack thousands of devices at once. An extremely difficult task.

The technology is based on a few simple rules. Complete transparency—any participant can see what happened and when. There's no single point controlling the system. And most importantly: security. Thanks to hashes and distributed storage, data tampering is virtually impossible.

Why all this? Blockchain allows people to transfer valuable information directly, without intermediaries. Cryptocurrencies exist precisely on this principle: money is sent without banks. But the technology's applications are much broader: inventory control, medical records, property registration, digital IDs—blockchain is suitable for anything where an honest, unadulterated history of transactions is important.

Simply put, blockchain is a secure chain of records maintained by thousands of participants. It operates in such a way that the system remains fair and transparent even without a controlling authority. And it is precisely this feature that makes the technology one of the most discussed and rapidly growing today.

What does blockchain have to do with VO?

[Svetlana]

Indirect.
Let me explain: a byproduct of the SVO is the sanctions imposed. Crypto allows us to circumvent them. Circumvent them in both directions.

If I transfer money from Germany to Russia today using crypto, imagine how easily this tool is used by various companies purchasing the necessary components for the production of devices used in water cooling systems. Rubles are converted into crypto, the crypto into euros, and these euros go to the manufacturer.

[barbos]

What's stopping you from doing the same with cash, monetary gold, or barter? All of these are easily circumvented in all directions and offer an anonymity that Bitcoin lacks.

[Svetlana]

The borders with their border guards are a nuisance

[barbos]

Goods paid for with cryptocurrency will be examined by customs officials on both sides of the border, and border guards may be involved if necessary.

[Svetlana]

At the border, they don't care how the goods were paid for. They only care about the quantity.

[barbos]

If it doesn't matter whether the goods are paid for at the border and how, then what's the problem with the payment method?

The most direct...the cryptocurrency that our waiting people transfer to terrorists and Ukrainian Nazis is carried out, including through the blockchain, in encrypted form, of course.
Therefore, blockchain is the same tool for communication and transmission, reception of information between interested people or structures.

So, electricity consumption will also be thousands of times higher than with conventional recording. And why such happiness? It's no wonder this whole thing is dying out, say, in banks. Who's going to pay for this banquet? In the case of crypto, it's clear—suckers. But in a normal economy?

[Dart]

In principle, the chain can be compromised at the global level of network segments. But for now, all participants are in on the act.

Cryptocurrency is convenient for many, including all sorts of government intelligence/espionage agencies. The question is: when will this whole crypto-festival come to an end?

At the next crisis of the capitalist economy, all this crypto will turn into simple numbers on computer monitors.

[barbos]

There's no need to wait. Just remember what happened with NFTs, which were once incredibly popular recently. There was a huge bubble that swept away a bunch of gullible people.

[Axe Yeti]

When they decide it's time to milk... as long as crypto is doing its job, it won't completely collapse. There's a lot of speculative money floating around there, money that used to be in oil. Did oil prices go up significantly when Israel started bombing all the countries around it? And there won't be any big price increases because speculators have fled to crypto.
"Since March 2002, oil prices have been on a prolonged and virtually uninterrupted rise. Experts attribute this to a number of factors: the war in Iraq, declining oil production in Mexico, the UK, and Indonesia, rising oil consumption, and the depletion of easily extracted reserves in the Persian Gulf. On February 29, 2008, the price of Brent crude exceeded $100 for the first time in history. The market has responded to any instability in the Middle East with price increases: on June 6, oil prices rose by a record $10,45 in one day due to rumors that Israel might launch a missile and bomb strike on Iran."

Cryptography in general, which is used for intelligence and cryptocurrency, is two very different things.

[kill the fascist]

Did you come up with it yourself? My post didn't mention anything about cryptography. So keep the "difference" to yourself.

[barbos]

In your harmless universe, everyone has their own cryptography? What about the other wards?

[kill the fascist]

I'm sorry, I don't communicate with idiots.

[barbos]

That's right! Support! By the way, what did the orderlies treat you to for dinner today?

A new block appears – the entire network checks it for authenticity

Yeah, right. You hack this block, and it changes on all computers connected to the network. Using the same technology it was created with. Blockchain is a technology created by people with access to massive computing power to steal money, or more precisely, the goods that can be obtained with it, while remaining essentially undetectable.
All you need to rip off the suckers who use blockchain is a powerful server node and access to its protocols (and good programmers, of course). No, I'm not pointing a finger at the US Cyber ​​Command, of course! They're holy men...

[novel66]

There are no 100% secure safes. Anything can be hacked.

Hack this block - it changes on all computers connected to the network

It's impossible to hack a block because it's immutable. Once the block is complete, you can't do anything with it.

[Igool]

Quote: Mikhail3

Yeah) You hack this block - it changes on all computers connected to the network.

When a block is hacked, the hash controlling it will inevitably change. The system will then flag this block as invalid. Since the system already contains hundreds of copies of this block that match the original hash, the block will only be used if it matches the hash.

[Maks1995]

Comrade commentators, you've gone in the wrong direction, IMHO.
1) At one time, Kadyrov, the banks, the security forces, and the local elite (like Abkhazia) all declared an interest in crypto. The price hikes for video cards, the energy shortages in the southern regions and the Caucasus, and the seizure and export of mining farms to the Caucasus and the security forces were all reportedly linked to this "interest" (or, one might say, the redistribution of power in the interests of the "elite").
2) Smart Assets banking – these have become fashionable in recent years. This is it.
3) The Digital Ruble, hyped for years and finally arriving... well, that's it. Essentially, adding money out of thin air. There was cash and non-cash. Now there's "digital" added in.

So while you're discussing and guessing about the "transfers... our waiting ones" hype, the elite is already making money off of it. Essentially, out of thin air...

[gridasov]

The very idea of ​​creating such a system is certainly necessary. However, it's important to understand that its operation is built on binary logic. In other words, the issues of openness and accessibility are misinterpreted. And these issues should not be confused with the need for absolute anonymity and the inaccessibility of many processes to third parties.

[acetophenone]

Why all this? Blockchain allows people to transfer valuable information directly, without intermediaries.

Government agencies that want to rule everything, control everything and have a share of everything look at you with disapproval!

[1944-1989]

cryptocurrency
- financial pyramid
- money laundering
- a method of payment for illegal work such as mercenary work, assassination, espionage, etc.

[Ponimatel]

Our electoral commission will defeat any blockchain.
