㈠ Tutorial for getting started with blockchain

However, there are very few simple and easy-to-understand introductory articles. What exactly blockchain is and what makes it special is rarely explained.
Next, I will try to write a best-understood blockchain tutorial. After all, it is not difficult. The core concept is very simple and can be explained clearly in a few sentences. I hope that after reading this article, you will not only understand the blockchain, but also understand what mining is, why mining is getting more and more difficult, and other issues.
It should be noted that I am not an expert in this area. Although I have been paying attention to it for a long time, my detailed understanding of blockchain started at the beginning of this year. You are welcome to correct any errors or inaccuracies in the article.
1. The essence of blockchain
What is blockchain? In a word, it is a special distributed database.
First of all, the main function of blockchain is to store information. Any information that needs to be saved can be written to the blockchain and read from it, so it is a database.
Secondly, anyone can set up a server, join the blockchain network, and become a node. In the world of blockchain, there is no central node. Every node is equal and stores the entire database. You can write/read data to any node, because all nodes will eventually be synchronized to ensure that the blockchain is consistent.
2. The biggest features of blockchain
Distributed databases are not a new invention, and there have been such products on the market for a long time. However, blockchain has a revolutionary feature.
Blockchain has no administrator, it is completely centerless. Other databases have administrators, but blockchain does not. If one wanted to add auditing to the blockchain, it would not be possible because it is designed to prevent the emergence of a central authority.
It is precisely because it is unmanageable that blockchain can be uncontrollable. Otherwise, once big companies and large groups control the management, they will control the entire platform, and other users will have to take orders from them.
However, without an administrator, everyone can write data into it. How can we ensure that the data is trustworthy? What if it is modified by a bad person? Please read on, this is the wonderful thing about blockchain place.
3. Block
Blockchain is composed of blocks. Blocks are much like database records. Every time data is written, a block is created.
Each block contains two parts.
Head: records the characteristic values ​​of the current block
Body: actual data
The block header contains multiple characteristic values ​​of the current block.
Generation time
Hash of the actual data (i.e. block body)
Hash of the previous block
...
Here, you need to understand what a hash is , which is necessary to understand blockchain.
The so-called hashing means that the computer can calculate a characteristic value of the same length for any content. The hash length of the blockchain is 256 bits, which means that regardless of the originalWhatever the initial content is, a 256-bit binary number will be calculated in the end. And it can be guaranteed that as long as the original content is different, the corresponding hash must be different.
For example, the hash of the string 123 is (hexadecimal), which is 256 bits when converted to binary, and only 123 can get this hash. (Theoretically, it is possible for other strings to get this hash, but the probability is extremely low and can be approximated as impossible.)
Therefore, there are two important inferences.
Corollary 1: The hash of each block is different, and the block can be identified by the hash.
Corollary 2: If the content of the block changes, its hash will definitely change.
4. The non-modifiable nature of Hash
Blocks and hashes have a one-to-one correspondence, and the hash of each block is calculated based on the block header (Head). That is to say, the characteristic values ​​​​of the block header are connected together in order to form a very long string, and then the hash is calculated on this string.
Hash = SHA256 (block header)
The above is the calculation formula of block hash. SHA256 is the hash algorithm of the blockchain. Note that this formula only contains the block header and not the block body. In other words, the hash is uniquely determined by the block header.
As mentioned before, the block header contains a lot of content, including the hash of the current block body. , and the hash of the previous block. This means that if the content of the current block body changes, or the hash of the previous block changes, it will definitely cause the hash of the current block to change.
This point has great significance for blockchain. If someone modifies a block, the hash of the block changes. In order for subsequent blocks to still be connected to it (because the next block contains the hash of the previous block), the person must modify all subsequent blocks in sequence, otherwise the modified block will be removed from the blockchain . Due to the reasons mentioned later, hash calculation is very time-consuming, and it is almost impossible to modify multiple blocks in a short period of time, unless someone controls more than 51% of the computing power of the entire network.
It is through this linkage mechanism that the blockchain ensures its own reliability. Once the data is written, it cannot be tampered with. This is just like history, what happened happened, and it can’t be changed from now on.
Each block is connected to the previous block, which is where the name blockchain comes from.
5. Mining
Since synchronization between nodes must be ensured, the adding speed of new blocks cannot be too fast. Just imagine, you have just synchronized a block and are preparing to generate the next block based on it, but at this time, another node generates a new block, and you have to give up half of the calculations and synchronize again. Because each block can only be followed by one block, you can only generate the next block after the latest block. So, you have no choice but to sync as soon as you hear the signal.
So, the inventor of the blockchain, Satoshi Nakamoto (this is a pseudonym, and his true identity is still unknown) deliberately made it difficult to add new blocks.His design is that on average, the entire network can generate a new block every 10 minutes, which is only six per hour.
This output speed is not achieved through commands, but by deliberately setting up massive calculations. In other words, only through an extremely large amount of calculations can the effective hash of the current block be obtained and the new block added to the blockchain. Because the amount of calculation is too large, it cannot be done quickly.
This process is called mining, because the difficulty of calculating a valid hash is like finding a grain of sand that meets the conditions among the sand in the world. The machine that calculates hashes is called a mining machine, and the person who operates the mining machine is called a miner.
6. Difficulty coefficient
After reading this, you may have a question. People say that mining is difficult, but isn’t mining just about using a computer to calculate a hash? This is the strength of computers. How could it be? It becomes very difficult, why can’t it be calculated?
It turns out that not just any hash can be used, only hashes that meet the conditions will be accepted by the blockchain. This condition is particularly harsh, causing most hashes to fail to meet the requirements and must be recalculated.
It turns out that the block header contains a difficulty coefficient (difficulty), which determines the difficulty of calculating the hash. For example, the difficulty coefficient of the 100,000th block is 14484.16236122.
The blockchain protocol stipulates that the target value (target) can be obtained by dividing the difficulty coefficient by a constant. Obviously, the greater the difficulty coefficient, the smaller the target value.
The validity of the hash is closely related to the target value. Only hashes smaller than the target value are valid, otherwise the hash is invalid and must be recalculated. Since the target value is very small, the chance that the hash is smaller than this value is extremely slim, and it may be calculated 1 billion times before it is considered a hit. This is the fundamental reason why mining is so slow.
As mentioned earlier, the hash of the current block is uniquely determined by the block header. If the hash of the same block needs to be calculated repeatedly, it means that the block header must keep changing, otherwise it is impossible to calculate different hashes. All feature values ​​in the block header are fixed. In order to make the block header change, Satoshi Nakamoto deliberately added a random item called Nonce.
Nonce is a random value. The role of the miner is actually to guess the value of Nonce so that the hash of the block header can be smaller than the target value so that it can be written to the blockchain. Nonce is very difficult to guess. At present, we can only use trial and error one by one through exhaustive methods. According to the protocol, Nonce is a 32-bit binary value, which can reach a maximum of 2.147 billion. The Nonce value of the 100,000th block is 274148111. It can be understood that the miner started from 0 and calculated 274 million times before obtaining a valid Nonce value so that the calculated hash can meet the conditions.
If you are lucky, you may find Nonce in a while. If you are unlucky, you may have calculated 2.147 billion times without finding the Nonce, which is the current area.It is impossible for the block to calculate a hash that satisfies the condition. At this time, the protocol allows miners to change the block body and start a new calculation.
7. Dynamic adjustment of difficulty coefficient
As mentioned in the previous section, mining is random, and there is no guarantee that a block will be produced in exactly ten minutes. Sometimes it can be calculated in one minute, and sometimes it may take several hours. No result. Overall, with the improvement of hardware equipment and the increase in the number of mining machines, the computing speed will definitely become faster and faster.
In order to keep the output rate constant at ten minutes, Satoshi Nakamoto also designed a dynamic adjustment mechanism for the difficulty coefficient. He stipulated that the difficulty factor should be adjusted every two weeks (2016 blocks). If the average block generation speed in these two weeks is 9 minutes, it means that it is 10% faster than the legal speed, so the next difficulty factor will be increased by 10%; if the average block generation speed is 11 minutes, it means It is 10% slower than the legal speed, so the difficulty factor of the next step must be lowered by 10%.
The difficulty coefficient is adjusted higher and higher (the target value is getting smaller and smaller), which makes mining more and more difficult.
8. Forks of the blockchain
Even if the blockchain is reliable, there is still an unresolved problem: if two people write data to the blockchain at the same time, that is to say, two people write data to the blockchain at the same time. Blocks join because they are connected to the previous block, forming a fork. Which block should be adopted at this time?
The current rule is that new nodes always adopt the longest blockchain. If there is a fork in the blockchain, it will look at which branch is behind the fork to reach 6 new blocks first (called six confirmations). Based on a block calculation of 10 minutes, it can be confirmed in one hour.
Since the generation speed of new blocks is determined by computing power, this rule means that the branch with the most computing power is the authentic blockchain.
9. Summary
Blockchain, as an unmanaged distributed database, has been running for 8 years since 2009 without major problems. This proves it works.
However, in order to ensure the reliability of data, blockchain also has its own price. The first is efficiency. You have to wait at least ten minutes to write data to the blockchain. All nodes synchronize the data, which requires more time. The second is energy consumption. The generation of blocks requires miners to perform countless meaningless calculations. This is Very energy consuming.
Therefore, the applicable scenarios of blockchain are actually very limited.
There is no management authority that all members trust
The written data does not require real-time use
The benefits of mining can make up for its own costs
If the above conditions cannot be met, then the traditional database is Better solution.
Currently, the largest application scenario (and possibly the only application scenario) of blockchain is the cryptocurrency represented by Bitcoin.

㈡ What are the wrong application scenarios for blockchain technology?

What are the wrong application scenarios for blockchain technology? Four major misunderstandings about blockchain application scenarios, we will answer them one by one for you

​Attention
Today, let’s talk about the common misunderstandings about blockchain application scenarios. In order to prevent the misunderstandings from deepening, it is necessary for Xuanling Technology to explain . What is blockchain? Is blockchain equal to Bitcoin? Is the blockchain public? Is the ledger immutable? Is the financial industry not suitable for blockchain? With the above questions, we will answer them one by one.

What is Blockchain?

Blockchain technology is a decentralized ledger that allows a shared set of computing systems to agree that transactions between multiple parties are authentic . These results will be permanently recorded in a cryptographically secure manner and continuously coordinated and updated. Because the ledger is distributed among all transaction participants, it exists in multiple locations simultaneously, making it extremely difficult to manipulate entries or tamper with data without other parties noticing. Therefore, what makes blockchain so important is its ability to automate trust and transparency among the parties using it.

Perhaps one of the most important innovations in the blockchain space is the reinvention of smart contracts. Smart contracts have been around for decades but are now being reimagined to operate and automate business processes in a completely decentralized manner, enabling shared rules of engagement, behaviors, and business processes to be automated and enforced across the entire ecosystem. Smart contracts extend blockchain applications beyond cryptocurrencies.

Myth 1: Blockchain is equal to Bitcoin.

(iii) The blockchain industry is ushering in a new market trend. What bottlenecks exist in the development of the blockchain industry?

Blockchain technology is a new distributed infrastructure. and computing paradigms that enable the sharing, replication, and authorization of distributed ledgers. It has the characteristics of multi-point consensus and is difficult to tamper with. It solves the problem of how to enable cross-institutional trust transactions in business networks, connecting all parties involved in financial services, and brings challenges of breaking down data silos and improving data quality. It has the potential advantages of security and lower transaction costs. Enhance risk control capabilities and have broad application prospects in the financial field. The blockchain industry is ushering in a new market trend, and there are some bottlenecks in the development of the blockchain industry. Only by breaking through these bottlenecks can we usher in the spring of blockchain. bring better development.

Finally, the development of blockchain technology will bring certain network security issues. We must pay attention to and solve information security and network security issues. Blockchain technology is not inherently secure. Any software system inevitably has defects and vulnerabilities, and will face attacks from the Internet. Poorly designed and poorly managed blockchain systems can be vulnerable to attack. In applications in the financial industry, data is an asset, so we should have a comprehensive understanding of the security of the blockchain, and first put security design and self-control first to avoid the occurrence of Bitcoin theft.

㈣ How to solve blockchain security issues

One characteristic of blockchain projects (especially public chains) is open source. Open source code improves the credibility of the project and allows more people to participate. But the openness of source code also makes it easier for attackers to attack the blockchain system. There have been many hacker attacks in the past two years. Recently, the anonymous currency Verge (XVG) has been attacked again. The attacker has locked a vulnerability in the XVG code, which allows malicious miners to add false times to blocks. After stamping, new blocks were quickly mined, and nearly US$1.75 million worth of digital currency was obtained in just a few hours. Although the attack was successfully stopped, no one can guarantee whether the attacker will attack again in the future.
Of course, blockchain developers can also take some measures
The first is to use professional code audit services,
The second is to understand safe coding standards and nip problems in the bud.
Security of cryptographic algorithms
The development of quantum computers will bring major security threats to the cryptographic systems currently used. Blockchain mainly relies on the elliptic curve public key encryption algorithm to generate digital signatures for secure transactions. Currently, the most commonly used ECDSA, RSA, DSA, etc. cannot withstand quantum attacks in theory, and there will be greater risks. More and more Researchers are beginning to focus on cryptographic algorithms that are resistant to quantum attacks.
Of course, in addition to changing the algorithm, there is another way to improve security:
Refer to Bitcoin's handling of public key addresses to reduce the potential risks caused by public key leaks. As a user, especially a Bitcoin user, the balance after each transaction is stored in a new address to ensure that the public key of the address where Bitcoin funds are stored is not leaked.
Security of consensus mechanism
The current consensus mechanisms include Proof of Work (PoW), Proof of Stake (PoS), and Delegated Proof of Stake (DPoS). , Practical Byzantine Fault Tolerance (PBFT), etc.
PoW faces 51% attack problem. Since PoW relies on computing power, when an attacker has a computing power advantage, the probability of finding a new block will be greater than that of other nodes. At this time, it has the ability to undo transactions that have already occurred. It should be noted that even in this case, the attacker can only modify his own transactions and not the transactions of other users (the attacker does not have the private keys of other users).
In PoS, an attacker can only successfully attack when he holds more than 51% of the token amount, which is more difficult than 51% of the computing power in PoW.
In PBFT, the system is safe when the malicious nodes are less than 1/3 of the total nodes. In general, any consensus mechanism has its establishmentConditions, as an attacker, you also need to consider that once the attack is successful, the value of the system will be reduced to zero. At this time, the attacker will not get any other valuable rewards except destruction.
For designers of blockchain projects, they should understand the advantages and disadvantages of each consensus mechanism, so as to choose an appropriate consensus mechanism or design a new consensus mechanism according to the needs of the scenario.
Security of smart contracts
Smart contracts have the advantages of low running costs and low risks of human intervention. However, if there are problems with the design of smart contracts, it may cause greater losses. In June 2016, The DAO, Ethereum's most crowdfunded project, was attacked. Hackers obtained more than 3.5 million Ethereum coins, which later caused Ethereum to fork into ETH and ETC.
The measures proposed in this regard have two aspects:
The first is to conduct security audits of smart contracts,
The second is to follow the principles of safe development of smart contracts.
The security development principles of smart contracts include: be prepared for possible errors and ensure that the code can correctly handle bugs and vulnerabilities; release smart contracts with caution, do functional testing and security testing, and fully consider boundaries; maintain The simplicity of smart contracts; pay attention to blockchain threat intelligence and check for updates in a timely manner; be clear about the characteristics of blockchain, such as cautiously calling external contracts, etc.
Security of digital wallets
Digital wallets mainly have three security risks: First, design flaws. At the end of 2014, a serious random number problem (duplication of R values) caused users to lose hundreds of digital assets in a certain lottery. Second, digital wallets contain malicious code. Third, lost assets caused by loss or damage of computers and mobile phones.
There are four main countermeasures:
The first is to ensure the randomness of the private key;
The second is to verify the hash value before installing the software to ensure that the digital wallet software has not been tampered with ;
The third is to use a cold wallet;
The fourth is to back up the private key.

㈤ A brief discussion of several major applications of blockchain and which ones are pitfalls

What can blockchain do? Blockchain, a great technology that accompanied the birth of Bitcoin, is currently being used in the financial field to significantly reduce transaction costs and improve efficiency, which is enough to excite Wall Street. However, this is just the tip of the iceberg. Its potential applications are very broad and will subvert every aspect of our lives in the future.

The Internet is an information network, with 0s and 1s flowing in it. Blockchain is a value network, and its role is to transmit value, unlike the Internet for data transmission.

Speaking of value transfer, there is a very simple scenario, such as payment, I have 100 yuan in hand, and I want to transfer it to the group. I can use WeChat red envelopes or WeChat transfers. Here During the transaction process, the participation of a third party is required, and the transmission method of the blockchain is point-to-point transmission, which does not requireNo intermediate node is required. This is a very big difference between the blockchain and our existing architecture.

When it comes to peer-to-peer payments, many people will think of Bitcoin, because most people know blockchain from Bitcoin. What is the difference between blockchain and Bitcoin?

Blockchain is the technology behind Bitcoin; blockchain is a basic technical architecture that designs and implements an autonomous system with multi-party participation through a specific data structure and consensus algorithm.

The specific data structure is actually the name blockchain itself, that is, its data is placed in data blocks one by one, and then these data blocks are connected and implemented using a chain. "Consensus algorithm" is a very important concept in blockchain. Without synchronic algorithm, there would be no meaning of blockchain.

Introduction to Bubi Blockchain

Bubi Blockchain has been focusing on the R&D and innovation of blockchain technology and products since its establishment, and has a number of core technologies. It has made substantial innovations in many aspects and formed a number of core technical achievements, such as: mathematically provable distributed consensus technology, fast large-scale ledger access technology, multi-chain general ledger technology that supports business expansion, and heterogeneous ledger technology. Construct interconnection technology between blockchains, etc. On April 25, "Gege Points" introduced the concept of blockchain into the points system, jointly opened it up with multiple parties, issued and redeemed points, and promoted the circulation of points. Each cooperative institution can jointly participate in transaction verification, ledger storage, and real-time settlement; the third-party payment platform of the enterprise points issuer makes the entry and exit of points more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, points, credit and other fields. Bubi has been committed to building an open value circulation network with decentralized trust as the core, allowing digital assets to flow freely.

Having said that, let’s analyze the difference between blockchain and Bitcoin?

1. Essential difference. For the world, Bitcoin is a digital currency based on cryptography, while blockchain, as we just said, is a value transfer protocol. There is an essential difference between the two, because one is a digital currency. , one is a value transfer protocol.

2. Algorithm. Bitcoin's consensus algorithm is based on a working algorithm called proof of work, POW. There are many different consensus algorithms in the blockchain. It can use either the Bitcoin POW algorithm, the POS algorithm, or the DPS algorithm.

3. Transaction speed. Bitcoin is limited to a maximum of seven transactions per second. Please note that what is mentioned here is the maximum and not the average, because this is a very strict definition. For the blockchain, the number of transactions per second can actually reach tens of thousands or more, so this is also One major difference between blockchain and Bitcoin. Because many people will be confused and say that the blockchain technologyThe transaction speed is seven transactions per second, which is wrong. This is a limitation of Bitcoin. The blockchain can achieve very high transaction speeds based on its different consensus algorithms and linking methods.

4. Link form. Bitcoin is a blockchain based on the Internet, which means we call it a public chain. The blockchain can be in the form of a public chain, a private chain, or a consortium chain.

5. Limitations. It is recommended that everyone not touch some digital currencies related to blockchain. What's the reason? Bitcoin is a digital currency. Although it has very good and different characteristics, it does not comply with financial supervision. In other words, these 21 million Bitcoins were issued without national authorization and without national credit as a multiple. was released below. The blockchain also has some limitations. Although it is just a protocol and a technology, it is still a new technology in its infancy.

To summarize, blockchain is a relatively low-level protocol and a technical infrastructure, on which there are various consensus algorithms. If the blockchain is 1, the consensus algorithm may be 10 to 20, but the applications based on it may be one thousand or two thousand, or more. In other words, Bitcoin is only one of many blockchain applications. A realization. Therefore, Bitcoin and blockchain cannot be equated. Bitcoin is only a very elementary implementation of blockchain.

What can blockchain do? Blockchain problem? In the bill market, digital bills based on blockchain technology can become a safer, smarter, and more convenient bill form. Point-to-point transactions realized with the help of blockchain can break the existing functions of bill intermediaries and realize the disintermediation of bill value transfer; the construction and data storage of digital bill systems do not require a central server, eliminating the need for the development of central applications and access systems. costs, reducing the maintenance and optimization costs of the system under the traditional model, and reducing the risks caused by system centralization; based on the non-tamperability of information on the blockchain, once the transaction is completed, there will be no default, thereby avoiding "one Behaviors such as "selling too many tickets" and out-of-synchronization of payment and endorsement effectively prevent risks in the bill market. The securities trading market is also an area where blockchain technology has great potential. The current traditional securities trading model has the shortcomings of long transaction processes, low transaction efficiency, and high comprehensive costs. In addition, there are strong intermediaries and regulatory agencies, and the rights of financial consumers are often not protected. Applying blockchain technology, buyers and sellers can be directly matched through smart contracts, and the efficiency of transaction execution can be greatly improved. Settlement and delivery can be automatically realized through a distributed digital registration system. Since the data entered into the block is irreversible and can be copied to each data block within a short period of time, the information entered into the blockchain actually has a publicity effect, so the occurrence of the transaction and the confirmation of ownership will not occur. dispute.

What can blockchain do? Blockchain problem? Although it has not been established yetWith the mature underlying blockchain technology platform solution, technical problems such as capacity scalability, privacy protection, inability to settle on a net basis, and non-recourse afterward also need to be solved. Large-scale application of blockchain technology requires the reset of IT architecture and Reengineering business processes, but these are only technical issues. The real test of blockchain technology taking root and growing in the financial field is the ontology of regulatory agencies and financial institutions. Will the inherent "deregulation" and "decentralization" characteristics of blockchain make market entities have no motivation to drive technology? Innovation. However, since the blockchain is a technology based on mathematical algorithms, the establishment of a trust relationship between transaction parties does not require the use of intermediaries or authoritative centers at all, and the cost of establishing a trust relationship is almost zero (when the blockchain financial infrastructure and ancillary infrastructure are established (under the premise), and the blockchain code is open source and open, without geographical restrictions, and the network pattern is distributed and interconnected, laying a technical foundation for the establishment and development of inclusive finance and shared finance in the future, and creating material conditions for global financial integration and unification. From this point of view alone, blockchain technology will surely establish a core position in future financial development, and it will rely on and complement each other to win the future.

㈦ What are the applications of blockchain education

There are many directions for integrating blockchain in education, including my country’s “White Paper on the Development of Blockchain Technology and Applications in China” and the European Commission’s report "Blockchain in the Education Industry" has conducted a preliminary discussion on the application model of blockchain in the field of education.
The application models of blockchain in the field of education mainly include:
Intelligent transactions create an educational Taobao platform based on smart contracts, build communities to achieve true "self-organizing" operation of online learning communities, and non-school educational institutions join Multiple themes in the market jointly participate in the formulation of educational content and establish an accessible individual academic credit database to solve the global problem of academic fraud.
Online education branches are very broad, and the ecological structure applied to each branch is also different. Existing online platforms should seize opportunities for ecological optimization, not only in their own market segments, but also in achieving continuous optimization in the entire online education market.
