ⅠDoes the code of blockchain projects need to be sourced? Why?

Blockchain is a consensus mechanism, which means that such participants must be transparent, that is It is said that the running code must be open source code. The so-called open source code means that the code is visible.

Everyone can compile and execute the program they compiled, which also means that everyone can modify the code and run it. Under the current mechanism, it can be done no matter how the code is modified, as long as those who modify the code If people do not exceed 51%, then this kind of modification is meaningless and will instead waste your own computing power.

So, at least the people involved must know the code. If the code of a blockchain project is not open source, then the nodes running its program will be opaque, which is equivalent to you putting His agent is installed on his own node and will execute orders on behalf of this owner. It is equivalent to system developers controlling the entire network. How is this kind of blockchain possible?

From a conceptual perspective, if a blockchain project is compared to a machine, its working mechanism is transparent and it is a trustworthy machine. This is how we understand this. First, open source is a must for blockchain projects, not an option. Both public chains and alliance projects need to be open source. Second, open source and delivering source code are two different things. Different concepts, delivering source code is not an open, transparent, and joint process for everyone to participate.

For example, in Ethereum, a certain platform currency running on its platform once had a vulnerability and needed to be modified. This modification was directly reflected in the code. In the process of reading the code , I found that the relevant code of the currency appears in many places, which is used to deal with how the node should deal with this problem once it encounters this problem. These processing methods are all written in open source code and can be read by everyone. If the person in charge of the node If he approves this solution, he will run this program, which is equivalent to supporting the decision of this code. In fact, the blockchain is implemented through this mechanism.

Ⅱ What are the better forums or apps for sharing and learning blockchain technology tutorials

There are not a few people learning blockchain technology now, but blockchain training institutions Not a lot anymore. There are many blockchain communities and blockchain platforms on the Internet, such as Babbitt, Zhiquchain, Golden Finance, and other platforms, which contain information, knowledge and experience, videos, blockchain project cases, etc. in the blockchain industry. Personally, I think You can buy some blockchain books and combine them with some of the above-mentioned blockchain platforms to learn, summarize experience, and practice. After a period of time, you will have a new understanding of blockchain technology.

Ⅲ What is open source code and what is non-open source code?

Open source code refers to open source code, also known as source code disclosure, which refers to a software release model; conversely , if the source code is not disclosed, it is non-open source code.

General software can only obtain compiled binary executable files. Usually only the author or copyright owner of the software owns the source code of the program.

The authors of some software will make the source code public, which is called "source code disclosure". However, this does not necessarily meet the definition and conditions of "open source code" because the author may set the source code to be public. Conditional restrictions on the source code, such as limiting the objects that can read the source code, limiting derivatives, etc.

(3) Extended reading of the source code of blockchain gambling game website:

The role of open source code:

1. Disadvantages caused by the exclusivity of software achievements

The exclusivity based on intellectual property protection is a "commercial barrier" that prevents other companies from entering such markets. There is no relevant product response and no market competition, thus A monopoly was formed.

2. The harm caused by the confidentiality of software source code

Due to intellectual property protection, each company keeps the software source code confidential. It can only be circulated and exchanged within the company, and software technology experts and scholars cannot Conducting study and research results in repeated development and use of software, which is a waste of social labor. Moreover, the security and improvement of the software are limited.

Because the monopoly of the software industry has caused strong dissatisfaction in the academic community, the open source movement and the freedom movement were born. Open source software originated from the free software movement.

IV It only takes ten minutes to determine the authenticity of a virtual currency - a guide for beginners in the currency circle to prevent pitfalls< /p>

Recently, too many friends have asked me whether what currency (or chain) is a real blockchain project. To be honest, I don’t want to offend people, and there is no need to lie, so I am here to teach you. Here are some of the simplest judgment methods. You can judge by yourself. It takes about three steps and takes about ten minutes.

You don’t need to look at the fancy content on the homepage, just scroll to the bottom. Regular public chain projects have the following icon.

There is no kitten icon in the circle in the upper right corner. If not, they are basically fake blockchain projects. There is no need to look at the next two or three steps.

Then we click on the kitten and look at the three icons in the upper right corner. If both star and fork are 0, it is basically a copycat blockchain project.

If your page looks like this, look at the numbers behind all the stars and fork icons in it.

There is a website called coinmarketcap, which is the largest virtual currency collection center in the world. Just use the Internet. Enter the search bar found in the upper right corner.

Enter your currency name (full English name or English abbreviation). For example, if we enter ABC here, there will be several prompts. Let’s choose one and see which one it is. If there are none, explain thisThe coin failed the qualification review. If there is, but you are not sure, you can look at the official website address in the upper left corner of the coin and click on it to see if it is consistent with the website mentioned in the first step.

If it does not pass the qualification review, or if there is a coin with the same name but the corresponding official website address is different, it means that the coin is likely to be a fake blockchain.

Whether it is a public chain or a dapp, there will be varying degrees of open source source code. Generally speaking, public chains will be open source for desktop wallets, while dapps will be open source for smart contracts. Otherwise, it will not pass the review. The largest open source website at present is github (the icon looks like a kitten). Therefore, those that cannot even find the source code on the homepage are basically fake blockchain projects. This is the first step.

In order to confuse newcomers, many project developers will also make a so-called blockchain source code and put it on github, but blockchain developers can basically see it. The simplest way for beginners is to look at star and fork. The former indicates the attention of the project, and the latter indicates the number of clones of the project. If the sum of these two values ​​​​is less than 10, it basically has no technical content. Clone the project. This is the second step.

Another special note here is that there is only a mobile wallet and nothing else; or there is only a Chinese homepage but no English homepage and no open source address. Basically, they are 100% fake. Blockchain.

Here, I sincerely hope that everyone will take ten minutes to do a simple check before investing tens of thousands or hundreds of thousands.

IV How much does it cost to develop a blockchain application?

How much does it cost to develop a blockchain application? For example, let’s take a blockchain digital wallet.
There are still many types of blockchain digital wallet apps. For example, online applications can be divided into many types, including full node wallets, light wallets, and centralized wallets. In addition, they can also be divided into single chains. There are two types of wallets and multi-chain wallets, while offline applications can be divided into two types: paper wallets and hardware wallets.
The development costs of different types of blockchain digital wallets are very different. For example, single-chain wallets and multi-chain wallets have different development costs because they use different types of systems during development. What we can know is that it is more difficult to develop a multi-chain wallet, because the price will be much higher than that of single-chain wallet development.

VI What are the core technologies of blockchain system development-blockchain transaction system development-

Blockchain technology is an emerging technology today, but it is not This is too appropriate, because this technology was born with the emergence of Bitcoin ten years ago, but it is no problem to say that it is a very hot technology now. After 10 years of continuous updates, blockchain technology has finally seen relevant applications in the past two years, and has entered the blockchain 3.0 era. In the next 3-5 years, I believe there will be more fields that require blockchain Chain system to support. The following blockchain system development pathThe editor of loopodo will take you to take a look at several core technologies for blockchain system development.
1. Hash algorithm
Hash algorithm is the most commonly used algorithm in the development of blockchain systems. Hash function is also called hash function or hash function. The hash function can convert data of any length into a set of fixed-length codes through the Hash algorithm. The principle is based on a cryptographic one-way hash function. This function is easy to verify, but difficult to crack. Usually, the industry uses y =h (x) to represent it. This hash function implements operations on x to calculate a hash value y.
2. Asymmetric encryption algorithm
Asymmetric encryption algorithm is a secret key method. Asymmetric encryption algorithm requires two keys: public key and private key. . The public key and the private key are a pair. If the public key is used to encrypt data, it can only be decrypted with the corresponding private key. Because encryption and decryption use two different keys, this algorithm is called an asymmetric encryption algorithm
3. Consensus Mechanism
The so-called "consensus mechanism" is through the voting of special nodes. The verification and confirmation of the transaction can be completed in a very short time; for a transaction, if several nodes with unrelated interests can reach a consensus, we can think that the entire network can also reach a consensus on it.
Today’s blockchain consensus mechanisms can be divided into four major categories: Proof of Work (PoW), Proof of Stake (PoS), Delegated Proof of Shares (DPoS) and Pool verification pool.
4. Smart Contract
A smart contract is a digital, networked version of a traditional contract. They are computer programs that run on the blockchain and can execute themselves when conditions written in the source code are met. Once a smart contract is written, it can be trusted by users and the terms of the contract will not be changed. Therefore, the contract is immutable and cannot be modified by anyone.
Developers write code for smart contracts, which are used for transactions and any exchange between two or more parties. The code will contain some conditions that trigger automatic execution of the contract. Once written, the smart contract is automatically uploaded to the network. Once the data is uploaded to all devices, users can come to agreement with the results of executing the program code.
5. Distributed Storage
Distributed storage uses the disk space on each machine in the enterprise through the network, and combines these dispersed storage resources into a virtual storage device, and the data is distributed in Every corner of the enterprise. Massive data is divided according to the degree of structure, and can be roughly divided into structured data, unstructured data, and semi-structured data.
Lupda Network Technology focuses on blockchain system development, Ethereum development, blockchain trading system development, virtual currency platform development, currency trading system development, and digital currency walletsSystem development

Ⅶ How to check whether the open source code is decentralized

I am happy to answer this question for you
Today I will share with you the knowledge of open source code query for virtual currencies. Among them I will also explain it. If it happens to solve the problem you are facing now, don’t forget to pay attention to this site. If you have different opinions and opinions, please leave a message in the comment area and let’s get to the point now!

How to find the open source code of virtual currency and which ones are open
Query the source code of Bitcoin.

Online virtual currencies can be roughly divided into

The first category is the familiar game currency. In the era of stand-alone games, the protagonist accumulated currency by defeating enemies and winning money in gambling halls. He used these to buy herbs and equipment, but they could only be used in his own game console. At that time, there was no "market" among players. Since the Internet established portals and communities and realized the networking of games, virtual currency has had a "financial market" where players can trade game coins.

The second type is the special currency issued by portal websites or instant messaging tool service providers, which is used to purchase services on this website. The most widely used one is Tencent’s Q coin, which can be used to purchase value-added services such as memberships and QQ shows.

Now every digital virtual currency has open source code, how can we analyze it?
Five ways to distinguish: decentralization, constant "issuance", open source code, independent electronic wallet and third party trading platform.

1. Decentralization

Many people are vague about the concept of decentralization, and there are also many currency-related projects that are promoting this under the banner of decentralization. market.

1. Technical decentralization: Bitcoin and Litecoin are currencies of the entire digital currency, and blockchain technology is 2.0. A 5-year study in the United States failed to study this area and only reached 1.0.

2. Do not belong to any company, country or organization. For example, the RMB, the US dollar, etc. are all legal currencies, issued and controlled by the state, and are centrally controlled; there is also a central bank called Tencent's Q coin, which is called a virtual currency, not a virtual currency, and is issued by Tencent.

2. Why does the price rise? Constant "issuance".

In fact, in the true sense, the word "issuance" should not be used. There are 21 million Bitcoins and 84 million Litecoins. The initiators calculated this digital currency on a computer. It is preserved with a set of formulas, and an Internet program is used to determine how many pieces there can only be in the world. They are excavated.

I heard that mining, mining, and mining machines are limited in time and quantity, and cannot be changed by any individual or organization. If its source code is disclosed, no one can Can be dug. Things are rare and valuable, and the reason for mining is just like theThe more gold is mined, the less it becomes, so it is called mining, and the price will rise.

The RMB has been issued in excess, causing inflation and making it less and less valuable. The real digital currency is one that never evaporates, is constantly "issued" globally, and has real scarcity and deflationary characteristics.

3. Open source code, this is a key core.

Currently, there is only one regulatory platform for all digital currencies. The open source code is mature and must be reviewed by the world’s only digital currency regulatory platform. After passing, it will be listed on this platform and its open source code will be announced.

Another way is to see if Litecoin and Bitcoin are available on major trading platforms. All open and transparent transactions are free transactions.

4. Independent electronic wallet.

Cross-border payments can be made to a certain area.

5. Third-party trading platform

Closed trading platform and open trading platform

1. What is a closed trading platform? ?

For example, in those days when you were shopping by ticket and eating by ticket, you were from a chemical factory and you were from the Grain Bureau. Today you are not allowed to go to the Grain Bureau to eat with a meal ticket from the factory. It is controlled internally.
2. Open trading platforms, such as OKCOIN and Huobi, are all open. Litecoins purchased on any platform can be bought and sold on this platform, which is open and transparent.
In short, there are five major criteria for whether it is a true digital currency:
1. Decentralization; 2. Open source code; 3. Constant issuance; 4. Third-party trading platform; 5. Electronic wallet.
The basic stage of virtual currency
There is no definition and distinction between game currencies and stocks, derivative financial instruments, especially electronic currencies. In fact, there is an internal clue that can connect these different forms of virtual currencies, which is the maturity of personalized value. We logically summarize it as follows:
1. Bank electronic currency
Bank electronic currency was originally a "pseudo-virtual currency". It only has the form of virtual currency, such as digitization and symbolization, but does not have the essence of virtual currency and has nothing to do with personalization. For example, it is just the counterpart of paper money; it may be issued by a central bank; it may be in the same market as the currency market, etc.
But one thing about bank electronic currency breaks through the extension of currency - that is, it can be issued not by the central bank, but by information service providers, as was the case with several early electronic currencies. The second breakthrough is that the liquidity of bank electronic money far exceeds that of ordinary currency. Therefore, there is an implicit challenge to the pricing power of the currency price level.
For example, in overnight lending, if the same currency is circulated several times in the form of electronic currency, although from a traditional currency point of view, nothing has happened.However, from the perspective of virtual currency circulation velocity, it has actually changed the conditions for currency price levels.
2. Credit Information Currency
Stocks are the most typical credit information currency. Their essence is virtual and a virtual currency with personalized characteristics. It is the most realistic foundation of the current virtual economy. The stock market and derivative financial instruments market constitute a large-scale and unified virtual currency market. They are not only based on physical business, but also supported by a wide range of trust business, insurance business and other information services.
The so-called unified market refers to something specific, which means that this market as a whole can exchange with the currency market at the overall level of national income. Historically, only when the currency forms a unified market, that is, when all the subjects of the national economy are monetized, can the regulatory role of currency volume and interest rates on the national economy be discussed. The same principle applies to the virtual economy.
This issue is not without controversy. Although the scale of the virtual economy is now several times that of the real economy, after all, a large part of the real economy has not entered this unified market. If you compare gaming currency to stocks, it's still far behind in this regard. Only through the two stages of entertainment industrialization and industrial entertainment can it be possible to reach the level of a unified market.
Analyzing the stock market and derivative financial instruments market, one of the biggest differences between it and the general money market is that its circulation velocity cannot be directly determined by the central bank. For example, the price level of the stock index as a virtual currency cannot be directly determined by the central bank like interest rates, but is directly determined by information called people's "confidence."
The fundamentals of the central bank and the real capital market can only indirectly determine the stock market, not directly. So I think the stock market is an information market rather than a money market.
Compared with the mature virtual currency market, the performance of the stock market is incomplete in terms of main characteristics. The stock market integrates the noise at all reference points (that is, individual gain and loss values) into a unified reference value, which is synthesized with the standard value (the fundamental utility value, the general equilibrium value), forming a continuous market fluctuation around the utility value.
Although it is different from the money market with orderly centripetal movement centered on the central bank, it is no different from the money market. From the perspective of the real virtual currency market, incommensurable personalized value is the characteristic of this market. In this sense, the centralized stock market has not fulfilled this function, and the independent role of the stock market as a so-called "casino" has not yet been played.
3. Personalized Credit Vouchers
The fundamental function of virtual currency is to synthesize value "on the spot" of individuality, rather than to determine a rational value in isolation at an equilibrium point divorced from the real world. The significance of virtual currency is to establish a value system centered on the final consumer. After the virtual currency is fully realized, a single currency with only general equivalent functions will tend to be background-based.
Game currency is the experimental field for higher-level virtual currencies, and it is difficult to take on a big role. reasonThink of virtual currency as a real-world symbol of value. In general equivalent exchange, the specific use value and the non-homogeneous needs and personalized needs of people, the subject counterpart of the specific use value, are completely filtered out.
Virtual currency will change all this. Through virtual means, people's non-homogeneous needs and personalized needs will be anchored to fundamentals through individual reference points to synthesize value. Therefore, virtual currency must have two sides. On the one hand, it has the function of commodity exchange, and on the other hand, it has the function of barter exchange.
Overcome the relativity and subjectivity of value through the former, and achieve personalized value confirmation through the latter. In order to achieve this goal, virtual currency must undergo a huge transformation that is unknown to everyone, which is the transformation to a conversational system and become an interactive currency.
The bargain here is a bargain over the currency price level. Recall that within a few decades, humans have already realized the transformation from text to dialogue, which is exactly the direction of the transformation of virtual currency. The value of game currency is actually uncertain. People exchange game currency, and the happiness they may ultimately get from it, whether it is above or below the currency value, is uncertain until they participate in the game.
The game is a conversational process. Of course, the various value-added functions of game coins have not yet been developed in conjunction with personalized information services. If this value-added business is fully developed, game currency may become an advantage over stocks because it is not universal due to different merchants providing services.
Fully personalized virtual currency, possibly a currency card with additional information, whose value is yet to be confirmed. A virtual currency with specific undetermined functions and residual value can, on the one hand, have the same room for reinterpretation as text, and on the other hand, it has the potential for karaoke-style redevelopment.

Its information value has an open interface and can be added in value. If they are put into the secondary market exchange like the stock market, they may fluctuate up and down the basic par value based on their personalized information, and they will have more attractiveness like stocks.
Game currency only has the function of value circulation and does not have the function of a market platform, so it is only an imperfect virtual currency. The reason is that it lacks the corresponding industrial foundation.
