区块链可以造假吗知乎,区块链造假公司

区块链是一种分布式的数据存储技术，最初由比特币的发明者Satoshi Nakamoto提出。它可以用于存储和传输数据，使用加密算法保护数据的安全性，并且不受中心机构的控制。随着它的发展，区块链被用于更多的用例，如智能合约和金融服务。有人担心，这种技术可能会被滥用，从而导致造假。

首先，区块链技术可以被滥用来造假。这是因为区块链技术的去中心化特性，使得它可以被用于存储和传输假数据，而不受任何中心机构的控制。此外，区块链技术使用加密算法来保护数据的安全性，使得它更加难以被检测出。因此，区块链技术可以被滥用来造假，这是一个非常严重的问题。

其次，区块链造假公司也是一个值得关注的问题。这些公司利用区块链技术来提供造假服务，他们可以利用区块链技术来伪造数据，使其看起来像是真实的。这些公司可以利用这种技术来欺骗消费者，从而获取不正当的利益。因此，应该对这些公司加以严格的监管，以防止他们的滥用。

最后，防止区块链造假也是一个重要的话题。首先，应该加强对区块链技术的监管，以防止它被滥用。此外，应该加强对区块链造假公司的监管，以防止他们欺骗消费者。另外，应该加强对区块链技术的教育，让消费者更加了解区块链技术，以便能够识别和防止造假。

总的来说，区块链技术可能会被滥用来造假，而区块链造假公司也是一个值得关注的问题。因此，应该采取有效的措施来防止区块链造假，以确保数据的安全性和真实性。

㈠ Bitcoin can forge a non-existent record by controlling more accounting nodes than the entire network

Bitcoin attacks are not based on accounting calculations Yes, it is calculated based on computing power. When you control more than 51% of the computing power, you can return any completed transaction to the state before the transaction, but you cannot forge transactions
Suppose: You have 100 blocks After selling Bitcoin, wait for the accounting to be completed (get a complete data block). At this time, you can restart the calculation from the block before the transaction and open a new blockchain. This is the calculation you control. The computing power is greater than other people’s computing power. The speed of your newly opened blockchain is greater than the speed of the blockchain that previously recorded your transactions. Due to the characteristics of the blockchain, when you create a new blockchain, the length of this chain is longer than the length of the blockchain that records your transactions. After the chain, your new chain will be the main chain, and the blocks that previously recorded your transactions will be discarded. At this time, you will have modified the transaction
If you really want to forge transactions, you need to master all Bitcoins Wallet and accounting point, but at this time, there is no point in forging or not

㈡ What is the concept of blockchain? Is blockchain a scam? The most complete explanation of blockchain

What is the concept of blockchain?

On October 25, 2019, the country advocated the development of blockchain. Overnight, the blockchain concept became popular.

However, many people are hearing about blockchain for the first time.

So, what is blockchain?

Let’s take a look at it from an academic perspective:

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transactions. Information, used to verify the validity of its information (anti-counterfeiting) and generate the next block.

In fact, blockchain is essentially a decentralized database.

Is blockchain the same as Bitcoin? Blockchain is not Bitcoin. The first application of blockchain is Bitcoin.

What are the characteristics of blockchain? Now let’s take a look at several characteristics of the blockchain:

1. Decentralization:

The most important feature of the blockchain is decentralization, and the blockchain system is different Based on a centralized database, it is not controlled by any person or entity. Through distributed storage, data is completely copied and distributed on multiple computers, and each node realizes information self-verification, transmission and management.

2. Non-tamperability:

Blockchain systemIt also has the feature of being tamper-proof. In the blockchain system, each node is the center and no information can be changed, not even the administrator can modify this information. The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. This situation is basically impossible, thus eliminating the possibility of fraud.

3. Publicity:

In a blockchain system, all nodes in the network can easily access information. The foundation of blockchain technology is open source. In addition to private information being encrypted, blockchain data is open to everyone. Anyone can query blockchain data and develop related applications through public interfaces, so the entire system information is highly transparent. .

4. Independence:

Because the blockchain is decentralized, it can facilitate peer-to-peer transactions, so there is no need for a third party whether in transaction or exchange of funds. of approval.

Based on consensus specifications and protocols, the entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without any human intervention.

Let’s assume an environment: 6 people live in dormitory 188 of the university

There is a ledger in the dormitory for Xiao Li, who is good at calculation, to keep accounts.

In the beginning, when the dormitory sold paper boxes or bought some public items, Xiao Li would record them in the ledger. If Xiao Li wanted to enrich himself and made false accounts, there would be less money in the account books, but no one would know.

After all, there is already a general ledger room, who would have nothing to do to keep track of the ledgers?

However, one day, because Xiao Li took more, there were obvious errors in the account book. Now, he could no longer hide it, so Xiao Li had to admit his mistake and make up the money.

So, how to solve this problem?

If blockchain is used to solve the problem:

Everyone in the dormitory takes out a ledger, and every time a transaction occurs, everyone records it in their own ledger. , such problems will not arise, because everyone is keeping accounts and can see the transaction records and final results on the ledger.

Xiao Li can’t change, you can’t change, and neither can your lower bunk. No one can change it.

This is because the previous accounting model was a centralized accounting model, and the current accounting model is a decentralized accounting model, where everyone is the center and everyone is the accountant.

If someone wants to change it, it will obviously be ineffective if they only change the data on their own account book, unless they bribe three people.

So, is blockchain a scam?

With the emergence of the great benefits of blockchain, in a short period of time, the prices of blockchain-related assets have soared, and ordinary investors are becoming more and more interested in blockchain. And criminals have also taken aim at this. There are some criminals who wear the gorgeous cloak of "blockchain" and use the blockchain to commit fraud or issue digital currencies without permission, leading many people to think that the blockchain is a scam.

But in fact, it is not. Blockchain is just a technology. If it can be used well, it will benefit the public and promote the development of the industry.

In particular, the application of blockchain is very wide and can be applied to almost everything of value to human beings.

Medical field: For example, when you go to the hospital for medical treatment, you can directly check the previous medical treatment in your own database, which greatly saves medical resources and saves medical expenses for repeated examinations.

Food traceability: Do you know where the food on your table comes from? Which logistics team is transporting it? This information can be tracked using blockchain. It can provide us with a single source of truth.

Supply chain application: For example, when we buy a product on a certain product, it leaves the factory, goes to the distributor for logistics turnover, goes to the seller's store warehouse, and then reaches the consumer's hands. During these processes, if something goes wrong, only you will know about it, and others, especially consumers, will not.

Well, this is where I introduce you to the relevant knowledge about the concept of blockchain. I hope it can be helpful to you.

㈢ Can luxury goods be prevented from counterfeiting with blockchain technology? How about Anlian Cloud?

Blockchain technology is of great significance to the fight against counterfeiting of luxury goods. Zhongan Anlian Cloud is suitable for many industries. There are successful cases of cloud services for practical application solutions, such as BuBuChi and diamond anti-counterfeiting. They are also slowly showing their talents in luxury goods.

Is blockchain a scam?

Blockchain is legal. Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects. Article 123 of the "Civil Code of the People's Republic of China" states that civil subjects shall enjoy intellectual property rights in accordance with the law. Intellectual property rights are the exclusive rights enjoyed by obligees in accordance with the law with respect to the following objects: (1) Works; (2) Inventions, utility models, and designs; (3) Trademarks; (4) Geographical indications; (5) Trade secrets; 6) Integrated circuit layout design; (7) New plant varieties; (8) Legal regulationsSliding simple other objects.

㈤ Can blockchain anti-counterfeiting traceability really prevent counterfeiting

Hello, there is definitely no problem with anti-counterfeiting. What products do you sell? However, blockchain technology is currently almost Few companies have mastered it, and more tend to be concepts. The price of real blockchain anti-counterfeiting traceability is also very high, ranging from hundreds of thousands to millions. I hope you can distinguish it well and don’t spend a lot of money to buy it. It’s just an ordinary traceability system. If you have ordinary traceability needs, you can find Chinese anti-counterfeiting companies.

㈥ Blockchain wallet scams.

What I want to share with you today is a blockchain wallet scam.

At present, various blockchain projects are flying all over the market. Whichever industry is popular will have which chain and which currency!

These blockchain projects are financial investment projects and are different from the blockchain technology advocated in my country’s key development directions. It is a fund package that uses blockchain technology as a bait for packaging, speculation, hype, and money trapping.

Blockchain is a decentralized super ledger that cannot be copied, falsified, or changed. A technology like this is still used in many practical scenarios in banks, insurance, and large companies such as Alibaba and Tencent.

Many so-called blockchain projects do not have any service targets, so just build a blockchain. Who will they serve? Where will they be applied? It is nothing more than creating a concept. Raise the currency price to make money.

I think there are two types of people who understand human nature best in the world, one is psychologists, and the other is liars. In the eyes of these behind-the-scenes bosses and liars, the new technology of blockchain, mixed with virtual currency, is an excellent story framework that can be used to make money with a little processing.

Those mainstream virtual currencies do not have extremely short cycles and collapse at the speed of light like domestic MLM coins or altcoins. Instead, they fall, rise, rise, rise and fall in a long cycle, just like the stock market. . There is a saying in the currency circle that it is harder to keep money than to be a widow

Therefore, those who have the fantasy of getting rich all day long hold in the hands of these seeds that are said to be able to get rich, but they watch them fall every day. It goes up again and again, up and down again. Isn’t it like sitting on pins and needles? How many ordinary people can sit still?

At this time, the blockchain wallet came into being. “As long as you put the money on hand The virtual currency is deposited in my so-and-so wallet, the capital is guaranteed and the income is guaranteed, and it is quite comfortable to get rich while lying down."

There was once a very popular wallet product that claimed to guarantee principal and provide monthly interest rates as high as 10%-30%. The operation is even simpler than P2P. First deposit the virtual currency into the app account, then turn on the "smart dog" brick-moving mode, and then open the wallet every day and watch the assets rise. That is to say, you can make money while lying down.

Moreover, as long as you use the compound interest investment model and recruit people, the one-year return is conservatively estimated to be 700%! If you recruit people to level 10, the rate of return will be 1400%! Fools know how to make a fortune rich!

Haha, this is the brilliance of a trader. One product can clearly arrange the psychology of leeks!

The wallet, to put it nicely, is called "quantitative trading bricks" "In fact, it is just a disguised fund disk. The essence is fixed rebates. In fact, those traders in the past found that consumer rebates are not easy to use, so they started to package them. Seeing that the blockchain is hot now, they used mainstream coins to make an article. I packaged a wallet and said My wallet has high-frequency cash out and high-frequency trading functions. In the past, you used to use money to buy products, or you gave me money directly. You are worried. Now I don’t want money. You use the money to buy Bitcoins. Then put your Bitcoins in my wallet, and I will give you interest every day of the month based on the amount of coins you put.

Well, Bitcoin is money, and you bought your coins with money. In the end, he may shut down the Internet and run away, then take all your coins and go to the transaction himself. All cashed out.

You want his interest, he wants your principal!

The blockchain wallet model is actually a model that uses fixed rebates to attract investors. The difference is that the deposit is virtual currency. The most typical blockchain wallet is the plus wallet.

For example, after you deposit Bitcoin, you will receive rebates every day. The source of the rebates claims to have smart arbitrage as an income. source, and then return you the platform currency, and then exchange the platform currency with a digital currency in the international market, and then go to Huobi.com to withdraw cash to obtain profits. When you withdraw cash, you will be charged a handling fee. For example, if you withdraw within 28 days, you will be charged a 5% handling fee. If you withdraw after 28 days, you will only be charged a 1% withdrawal handling fee.

It was officially launched on May 1, 2018, and the plus wallet trading platform was launched in October. It collapsed in June 2019. After running for more than a year, this disk package became one of South Korea’s Team operation is actually driven by the Chinese. Six traders have been arrested by the Chinese police. This project has 1 million members participating and the funds involved reach 20 billion yuan.

Judging from the running time, this product has a long existence cycle, which should be beyond the imagination of many people at the beginning. The reasons are:

First, it uses What you invest in is virtual currency, and what you withdraw is also virtual currency. For these mainstream currencies, Leeks have better illusions, thinking that there is still a lot of room for appreciation, and it will be more profitable to keep them. Since you just put it away, why not keep it in your plus wallet?What about earnings? It delays the time for large-scale withdrawals to a certain extent.

Secondly, Plus Wallet spent a lot of money on publicity. One moment it sponsored some blockchain conference, the next it talked about developing new products and launching new systems, and the next it talked about going public. The purpose of this crazy campaign is to exchange time for space.

Let me introduce you to several methods of blockchain wallet in detail:

The first point is that the so-called arbitrage cannot support your subsequent rebate income. .

Because the real income from moving bricks is not a stable income, and it will not be as substantial as he described.

Like the plus wallet, based on the rebate data before the crash, it needs 700 million yuan in rebates every day to continue operating, so this number is astronomical. Obviously there is no way to do smart arbitrage. If you think you can, then you have nothing to do with it. With such high skills in moving bricks, do you still need to rely on rewards to attract people? You can move it yourself, and there are big institutions rushing to invest, so there is nothing to do with you!

The second point is that the money returned by the platform to the people in front is mainly the funds coming in from behind, which is exactly the same as the characteristics of the fixed rebate plate.

If you want a promotion reward system with up to 10 levels, as well as super high rebates, you also have to pay high deposit interest. Therefore, soon the subsequent funds will not be able to keep up with the speed of rebates, and problems will arise in the capital chain. The platform will shut down and run away.

The third point is that the platform currency exchange channel for Bitcoin can be closed at any time. As for when to close, only the trader can decide, so you are faced with huge risks at any time.

Point 4: It is stipulated that you will be charged a 5% handling fee for withdrawals within 28 days, and you will only be charged a 1% handling fee for withdrawals after 28 days. This purpose is to allow you to extend the withdrawal time as much as possible , he can deposit more funds into the capital pool.

Originally, everyone entered the currency circle because it is a decentralized technology. You store the currency in a real wallet, and as long as you keep your private key, no one can take it away from you. assets.

As a result, you hand over decentralized assets to some centralized platforms far abroad.

Let’s analyze it from another angle

The private key is a 256-bit binary code, encoded into numbers and letters. Finally, it is mapped into words to facilitate memory, also called mnemonics.

Some wallets have different mnemonics. The mnemonic phrase for plus is a bunch of random characters. Some wallet mnemonics must be made in Chinese, etc.

In short, the core of the blockchain wallet is to allow you to deposit mainstream currencies into other currencies.bag, and then return you a lot of their platform coins. Your coins are money, and their coins can only be coins. If you recommend others to come here to deposit coins, you will also get promotion benefits. In fact, you can understand its essence if you think about it. It is the same as getting money back, but it is just using coins. Then I will tell you my capital flow. It is safe. You don’t have to worry about crashing or running away, because I don’t touch the money. Who am I kidding? Coins are not money, right?

If you want your mnemonic phrase to be different, change it. Can it be imported into other wallets? It's definitely not possible. Only your wallet can be used. Doesn't this become a completely centralized platform?

㈦ The significance of blockchain technology in anti-counterfeiting and traceability

——Yinlian’s answer:

Blockchain can realize data traceability and non-tampering , because it is based on a distributed database established by cryptographic links, thus forming a data source that cannot be tampered with. Therefore, complete information records can be achieved in the entire process of products from production to circulation, providing comprehensive product data information to regulatory authorities, allowing them to complete product quality inspection and data interconnection and mutual sharing more efficiently. In this process, blockchain can solve Four issues:

First, information cannot be tampered with, consensus is reached and trust is established. In the network nodes composed of various participants, the business process forms data records. In the product logistics, warehousing, and production links, including raw material sources, processing, assembly and other information are stored in the blockchain network, providing regulatory authorities and cooperative enterprises with Or organizations provide data information for each link.

Second, the process is open and transparent. To achieve product anti-counterfeiting and circulation in the business process, identification chips can be implanted into the product and registered on the blockchain so that it has a digital identity, and then all the information of this digital identity can be recorded through a jointly maintained ledger. Such as source, circulation, etc., to achieve verification effect.

Third, save costs and improve efficiency. The data recorded on the blockchain are kept confidential, and the regulatory authorities store, transmit, verify, and analyze product information, and transfer it between different departments to achieve unified vouchers, full-process records, and corporate credit reporting, which can effectively solve the problem. Issues such as multi-party participation, information fragmentation, and repeated review of circulation links.

Fourth, information sharing. The circulation of enterprise product certification relies on the interconnection of public data resources among departments and institutions such as commerce, customs, quality inspection, industry and commerce, and banks. Under the review environment established by the blockchain, all departments obtain information simultaneously and establish a supply chain-based The credit evaluation mechanism is organically connected with various supply chain platforms to disclose and share information such as credit ratings, credit records, risk warnings, illegal and dishonest behaviors, etc.

The disadvantages of traditional anti-counterfeiting traceability have become very obvious. Anti-counterfeiting traceability has always been an important scenario in blockchain applications. Typical Ruyin Chain also starts from the anti-counterfeiting traceability scenario, hoping to create a blockchain suitable for commercial use. .

Compared with traditional centralized anti-counterfeiting traceability technology, Yinlian uses the underlying technology of blockchain, and merchants produce anti-counterfeiting codes themselves to eliminateIn addition to the trust issue caused by cheating by intermediary anti-counterfeiting vendors. The main process is as follows:
