Ⅰ What is the open source code of digital currency?

In recent years, blockchain digital assets represented by Bitcoin have become popular around the world. Domestic and foreign financial institutions, technology companies, investments The company and other participants have invested a large amount of human, material, technical and other resources to conduct research, development, design, testing and promotion of blockchain digital assets. To realize the main characteristics of blockchain digital assets, the core technology system of digital assets can be built by relying on 11 technologies in three aspects: security technology, transaction technology, and trustworthy assurance technology. First of all, security technology is used to ensure the circulation, storability, controllable anonymity, non-forgery, non-repeatable transactions and non-repudiation of blockchain digital assets. Digital currency security technology mainly includes three levels: basic security technology, data security technology, and transaction security technology. Basic security technology includes encryption and decryption technology and security chip technology. Encryption and decryption technology is mainly used in currency value generation, confidential transmission, identity verification, etc. of digital assets. The establishment of a complete encryption and decryption algorithm system is the core and foundation of the digital asset system and needs to be customized and designed by the national cryptography management agency. Security chip technology is mainly divided into terminal security module technology and smart card chip technology. Digital assets can be traded in the form of mobile terminals based on the terminal security module. As a carrier of secure storage and encryption and decryption operations, the terminal security module can provide effective security for digital assets. Basic security protection. Digital asset system trading platform blockchain technology research and development data security technology includes data secure transmission technology and secure storage technology. Data security transmission technology transmits digital asset information through ciphertext + MAC/ciphertext + HASH to ensure the confidentiality, security, and non-tamperability of data information; data security storage technology uses encrypted storage, access control, security monitoring, etc. Store digital currency information to ensure the integrity, confidentiality, and controllability of data information.
Transaction security technology includes anonymity technology, identity authentication technology, anti-repeat transaction technology and anti-counterfeiting technology. Anonymous technology achieves controllable anonymity of digital assets through blind signatures (including blind parameter signatures, weak blind signatures, strong blind signatures, etc.), zero-knowledge proofs, etc.; identity authentication technology verifies user identities through certification centers to ensure digital assets The validity of the trader’s identity; anti-repeated transaction technology ensures that digital assets are not reused through digital signatures, serial numbers, timestamps, etc.; anti-counterfeiting technology ensures the authenticity and transaction of digital assets through encryption and decryption, digital signatures, identity authentication, etc. Authenticity. Secondly, use trading technology to realize online trading and offline trading functions of digital assets. Digital asset trading technology mainly includes two aspects: online trading technology and offline trading technology. As a currency with legal status, digital assets cannot be rejected by any unit or individual, and digital assets can be traded online or offline. Online trading technology realizes the online trading business of digital assets through online device interaction technology, online data transmission technology and online transaction processing; offline trading technology uses offline device interaction technology, offline data transmission and so on.Technology and offline transaction processing to realize offline trading business of digital assets. Finally, trustworthy assurance technology is used to provide a safe and credible application environment for the issuance, circulation, and trading of blockchain digital assets. Digital asset trust assurance technology mainly refers to trusted service management technology. Based on the Trusted Service Management Platform (TSM), it ensures the security and trustworthiness of digital asset security modules and application data, and provides security chips (SE) and application life to digital asset participants. Cycle management function. Trusted service management technology can provide various services such as application registration, application download, security certification, identification management, security assessment, and trusted loading for digital assets, which can effectively ensure the security and credibility of the digital asset system.
What is blockchain? Blockchain technology, referred to as BT (Blockchain technology), also known as distributed ledger technology, is an Internet database technology that is characterized by decentralization, openness and transparency, allowing everyone to participate in database records. Blockchain Technology Development Blockchain Technology Development What is a blockchain system? The blockchain system is a database system with integrity. Data written into the system will be automatically copied to the nodes of the blockchain. It can realize transactional data storage, support the management and development of databases in various industries, and combine a variety of needs. to make. 294.497 billion U.S. dollars, an increase of 2.60%. A total of 5 new projects entered the TOP100 this week, namely FST, ZB, WIX, WAX, and MXM. On August 11, the price of Bitcoin was US$11,523.58, an increase of 3.20% from last week, and the price of Ethereum was US$216.09, a decrease of 3.86% from last week. This week's 24-hour transaction volume increased by 2.63% compared with the same period last week; among the TOP100 projects, the total market value and average market value of currency projects increased the largest, and the classification composition of the TOP100 global blockchain assets projects was stable.

Ⅱ How to check whether 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 currency, which 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 views, please actively 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 category is portal websites or instant messagingThe special currency issued by the information tool service provider 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 and mining, and the mining machines used for mining, are limited in time and quantity, and cannot be changed by any individual or organization. If its source code is made public, no one can Can be dug. Things are rare and valuable, and the reason for mining is just like the gold on the earth is mined less and less, 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 region.

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, during overnight lending, if the same currency is circulated several times in the form of electronic currency, although from the perspective of traditional currency, nothing has happened, from the perspective of the circulation speed of virtual currency, it has actually happened. Conditions that change the price level of money.
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 combine game currency withStock comparison, its progress in this regard is still far behind. 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 gains and losses) 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. The ideal virtual currency is a real-world symbol of value. In general equivalent exchange, the specific use value and the subject counterpart of the specific use value - the non-homogeneous needs and personalized needs of people, 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 with 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. When people exchange game coins for game coins, will the happiness they ultimately get from them be above or below the currency value?, it is uncertain until the time of participating 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.

Ⅲ Hot! Create and play with your own blockchain in 5 minutes

Blockchain is developing so fast this year! From an unfamiliar concept at the beginning, it has now taken off in various industries. A single spark has the potential to start a prairie fire. I really hope I can have my own blockchain to practice with! But how can one person and one computer set up a blockchain environment? The blockchain is so popular that it is not easy to say that I love you!


Don’t Worry! The editor has been addicted to blockchain and smart contracts and can’t extricate himself! Now I will take you step by step to start from scratch and create your own blockchain in 5 minutes! ~
The SuperVessel platform developed by IBM China Research Institute provides a blockchain development and testing environment for blockchain enthusiasts and developers. Through this platform, users can create multi-node blockchains based on Hyperledger Fabric for free and super quickly, and play with smart contracts on their own chains.

1. Register an account
Access the public beta address of SuperVessel blockchain service: 8800/bc.
Click the Log in button in the upper right corner, click Register in the pop-up window, fill in your email and password and submit. At this time, it is recommended to check the activation email in your mailbox and activate your account (Editor's tip: It doesn't matter if you activate lazily, but some advanced services must be activated before they can be used).
2.
Quickly create your own blockchain
After registration is completed, return to the homepage and click on the huge GIVE ME A BLOCKCHAIN ​​(Give me a blockchain!) Press the button. Select the Consensus Plugin (consensus plug-in) and Size (number of blockchain network nodes) you want in the pop-up box.
Editor's note: Currently there are two consensus plug-ins officially provided by Hyperledger Fabric: noops and pbft.
After clicking Submit, you will get your own blockchain in a few seconds and automatically enter the monitoring panel. That’s right, getting your own blockchain is that simple!
After entering the monitoring panel, you can see that the left side is the smart contract management panel, including the management and deployment of smart contracts; the right side is the network panel, which displays the applied blockchain network status, topology, and connections between nodes. Latency information, etc. are clear at a glance; click the telescope icon in the upper right corner to monitor the log information of each node in real time. The bottom is the blockchain panel, which shows the overall situation of the current blockchain. In the initial state, there is only one block.
3. Deploy and use smart contracts
Next, the editor will teach you how to deploy and use smart contracts on your own blockchain.
Under the Smart Contracts tab of the smart contract management panel, 2 smart contracts are listed as examples, namely map and chaincode_example02. The map contract can store key-value pairs, and the chaincode_example02 contract can simulate transfers and queries between two people.
Editor's note: The code for these two sample contracts can be found in the Hyperledger Fabric source code.
Take the deployment and use of the chaincode_example02 contract as an example:
Deploy the contract
Click the Deploy button corresponding to the chaincode_example02 contract, and fill in the initialization value of the contract, including the contract name, initial function, and initial parameters. The initial function of the contract is init, and the initial parameters need to be filled in according to the format, such as ["a", "100", "b", "200"], which means registering two people a and b, giving them 100 units and 200 units respectively.
Click the Deploy button and the contract will be deployed in your blockchain. The process will take about 20 to 40 seconds. When a new block appears on the blockchain panel, it usually means that the contract has been deployed.
Call the contract
After the deployment is completed, view the deployed contract instance under the My Deployment tab of the smart contract management panel.
Click the Invoke button below the Action to call the smart contract, and fill in the called method name and corresponding parameters (the method names and parameters of different contracts have different meanings, which are related to the content of the contract). For this contract, call the invoke method name and fill in the parameters ["a","b","50”], indicating that a transfers 50 units to b.
After clicking Submit to complete the call, you can view the blockchain situation, and a new block will be generated.


Query Contract
After the call is completed, you can query the contract execution results. Still under the My Deployment tab, click the Query button under Action to query the smart contract, and fill in the query method name and corresponding Parameters. If you choose the query method name, fill in the parameter ["a"], which means querying the current unit of a.
After clicking Submit, you can see that the current unit of a is 50. You can try querying b again!
OK, then you can continue to operate the contract, observe the blockchain situation, or deploy a new smart contract on the blockchain, such as map. For convenience, deploy, call and query the method name and parameter format of the contract It’s all filled out by default, you just need to choose a method name and change the parameters like a cat or a tiger! See how long you can play with the chain~
4. Upload and test your own private smart contract
In addition to the current With the two public smart contracts provided, you can also upload and test your own private contract! Only you can see the private contract.
Click Import private smart contract under the Smart Contracts tab.
Fill in the contract name and description, and After uploading the contract code file, click Import to complete the upload.
Then the contract I uploaded will appear in the Smart Contracts list, and it can be deployed, called and queried as before.

VI How to invest in blockchain projects

The term blockchain has been frequently used in various venture capital activities recently. Many investors have a premonition that the wind is coming and want to do some track layout in advance, but they do not want to pay tuition blindly. When talking about blockchain to many institutional investors, the basic answer is to look at it. The general feeling is that there are too few projects and the estimates are too high. The key is not understanding!

Blockchain

It is estimated that many people will talk about decentralization, and some will even call it a new technology that will subvert the field of self-media. But at this time, if you ask him what is so-called decentralization and how to achieve so-called decentralization to subvert the mainstream centralized network. It is estimated that it will be difficult for the other side to make a substantive statement. The latter can only be explained with some vague concepts. You should be careful at this point.

In fact, no one is trying to subvert traditional search engines through decentralization. Some people even want to start from data.Modify instant messaging and social networking from a privacy and security perspective. However, much of this is just a rote recitation of the so-called decentralization concept. In fact, for us, there are still many areas for improvement in the field of blockchain technology, so I still hope that we will not have too high expectations for the field of blockchain. Of course, if someone describes the cake of a blockchain project in front of you in a big way and seems to be omnipotent, then it is recommended that you be vigilant.

Of course, we can also check whether the so-called blockchain project has open source code. Generally speaking, a mature blockchain project has a strong community to support maintenance, so we can see its projects, comments, and even source code in the community. If a blockchain project does not even dare to open the source code, a perfect blockchain project should also consider the stimulating effect of issuing tokens on the entire ecosystem. For example, Bitcoin is used as a reward for network workload. It can stimulate and encourage people to operate in the network. It can be said that in a traditional complete blockchain network, tokens are used as fuel to stimulate the operation of the entire ecosystem. Currently, many unreliable projects issue tokens just for the sake of issuing tokens, without considering how the issued tokens stimulate the development of the entire network ecosystem. Projects like this don't last long. The essence of being a distributed community is transparency, so if a blockchain project cannot be open and transparent on key issues, then there is reason to question whether the project is reliable. For example, a good blockchain project will usually disclose the project's budget, progress, and transparency to gain the trust of investors. In contrast, bad projects are not transparent about key issues. Even if there are changes in the project, they are not explained publicly, making it difficult to trust.

Finally, we can look at the composition of project team members and consulting team members. Generally speaking, blockchain projects have relatively high requirements for team members. At least they should have considerable experience in blockchain and be able to establish an open source community, attract more people to participate in the community, and play a leading role. However, the advisory team primarily recognizes the market, so if more members than the development team become team advisors, and they are in the lead, then there is reason to be suspicious of the project.

The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the only approved "Smart Learning Factory 2020- Xueshuo Innovation Workstation" launched by the School Planning and Construction Development Center of the Ministry of Education of China. "Blockchain Technology Professional" pilot workstation. The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

VII What are the blockchain development tools?

Blockchain development tools are:

1. RemixIDE, the Ethereum computing platform is a block chain Chain's open source code distribution platform. The platform used to build Ethereum is x86-64Arm. The Ethereum platform uses many tools for blockchain to create andDeploy smart contracts. Remix is ​​one of them.

2.TruffleFramework, Ethereum-based applications are built under a framework called Truffle. It provides a flexible development environment including libraries that can enhance the customization of coding for new contracts and link with Ethereum-based applications. It also performs contract testing through an automated process using Chai and Mocha.

ⅧIs the pi coin open source code 314159 real?

Is the pi coin open source code 314159 real? The full name of Pi is Pioneers. It is an encrypted virtual currency, and like Bitcoin, it is a digital virtual currency. Pi Coin was founded by Stanford University in the United States and is a blockchain project. Its purpose is to become the most widely used cryptocurrency in the world. Users can use mining on this platform to obtain Pi coins. PI coins are generally obtained by mining coins in your own safety circle. If you want to establish a pi coin safety circle, it can only be opened after the first mining time reaches 72 hours. After the safety circle is established, you can bring people in. Users can increase mining computing power by establishing their own Pi coin safety circle. Generally, the number of people in the safety circle does not need to be too many, only 5 are needed. Many people say that the amount of Pi coins is too large, and it will definitely not be valuable. However, whether it is valuable or not is actually closely related to the number.
