❶ What is blockchain expansion

Expansion is when a container or carrier is not enough to support or carry the needs of existing things, we expand the capacity of the container A means of increasing the volume of the container or load to meet the increasing demand, thereby alleviating the pressure on the current container or load.
At the beginning of the birth of Bitcoin, Bitcoin founder Satoshi Nakamoto did not specifically limit the size of blocks. The maximum block size could reach 32MB. At that time, the average block size was 1~2KB.
At that time, there were few Bitcoin users and the transaction volume was not that large, which did not cause block congestion. However, as the price of Bitcoin has skyrocketed since 2013, more and more users have caused congestion on the Bitcoin network. The problem of rising user transaction fees gradually emerged.
Up to now, there is a backlog of hundreds of thousands of transactions on the Bitcoin blockchain at its peak. The average transaction fee of Bitcoin has increased 376 times since September 2010. The processing speed of 7 transactions per second is obviously too high. To meet user needs, the Bitcoin community began to explore how to “expand” Bitcoin.
By modifying the underlying code of Bitcoin, the purpose of improving transaction processing capabilities is achieved.
There are two development and design solutions for Bitcoin expansion itself, namely first-layer and second-layer expansion technologies.
· The first layer of expansion technology is to improve the blockchain itself, making the blockchain itself faster and larger in capacity. In general, it is to change the content of the consensus part of the blockchain.
· The purpose of the second-layer expansion technology is to move calculations off-chain, that is, to solve problems through side-chain technology.
Expansion protocol and outcome
Expansion protocol generally requires the support of miners, and can be roughly divided into methods such as modifying the block size, soft fork, hard fork, and segregated witness.
Take Bitcoin as an example:
Bitcoin is now split into the large block Bitcoin Cash (BCH) and Segregated Witness. Segregated Witness is now recognized as Bitcoin in the market, and the big block coin is named Bitcoin Cash. It is foreseeable that in the future development direction, Bitcoin will be dominated by off-chain transactions. Including Lightning Network and side chains. These two new things are currently immature, but many people have high hopes.
Bitcoin will develop a large number of Segregated Witness transactions and make more derivative technologies based on Segregated Witness. It is most likely that technology will drive Bitcoin forward.
Bitcoin Cash will focus on on-chain transactions, focus on developing currency functions, reduce transaction friction as the main method, and profit from a wider range of on-chain users as the main development direction.

❷ Is blockchain a lie?

"Blockchain" is an important concept in the new era. It is essentially a centralized database and a digital currency. underlying technologies. According to our popular explanation, the "blockchain" can be regarded as a ledger, and each bill is a block. However, this ledger is centralized, and it can be said that no company or team has jurisdiction over it. "Blockchain" technology is a unique informatization that is centralized and cannot cross-change information. Now in daily life, this technology has been applied to a series of applications such as electronic invoices and payment codes.
In today's life, many people use this guise to commit fraud. Direct sales disks, capital disks, technology disks and other names are used to lure people to make money and then run away. As a result, many people have lost their funds and have nowhere to defend their rights. In the end, I can only say that "blockchain" is a lie. There is no right or wrong in technology, it’s the people who are wrong.
With the progress of the times and the progress of society, the initial application of any technology will be subject to various positive and negative doubts. However, with the relative application and maturity of technology, coupled with the improvement of technology, various aspects around people have formed. This application will continue to improve, and I believe that these doubts will slowly dissipate in the near future.
The following is a summary of some blockchain scams that are often around you!
Trap 1: Blockchain is about issuing coins to make money
Trap 2: Conducting virtual currency transactions, promising low investment and high returns
Trap 3: Decentralization can solve all problems
Trap 4: With the extension of the blockchain, you can make money with a mining machine
Trap 5: Transactions on WeChat and Alipay to buy and sell virtual currencies
In short, the methods of scammers are also advancing with the times. Through our "eyes of wisdom", we can improve and enhance our adaptability, discover and alert ourselves, and prevent being deceived. Investors must be wary of various deceptive methods that offer low investment and high returns.

❸ Where is the data in the blockchain stored?

The data in the blockchain all exists in the terminal or in the server. Because we are talking about blockchain, its user terminal can also be a server, and the server can also be a user terminal, so it is all stored on these devices.

❹ What is the relationship between blockchain and big data storage

The relationship between blockchain and big data storage is as follows:
1. Data security: blockchain Let data truly flow with confidence
Blockchain, with its trustworthiness, security and non-tamperability, allows more data to be liberated. Let’s use a typical case to illustrate how blockchain promotes the generation of gene sequencing big data. Blockchain sequencing can use private keys to limit access rights, thereby circumventing legal restrictions on individuals' access to genetic data, and utilize distributed computing resources to complete sequencing services at low cost. The security of blockchain makes sequencing an industrialized solution, enabling global-scale sequencing and thus promoting the massive amount of data.increase.
2. Data openness and sharing: Blockchain ensures data privacy
The government holds a large amount of high-density and high-value data, such as medical data, population data, etc. The openness of government data is a general trend and will have an immeasurable impetus to the development of the entire economy and society. However, the main difficulty and challenge in data openness is how to open data while protecting personal privacy. Blockchain-based data desensitization technology can ensure data privacy and provides a solution for data openness under privacy protection. Data desensitization technology mainly uses encryption algorithms such as hashing. For example, the Enigma system based on blockchain technology can calculate data without accessing the original data, which can protect the privacy of data and eliminate information security issues in data sharing. For example, company employees can safely open access to their salary information and jointly calculate the average salary within the group. Each participant is informed of his relative position within the group but not of the compensation of other members.

3. Data storage: Blockchain is an tamper-proof, full-historical, strongly endorsed database storage technology
Blockchain technology, through the network All nodes in the network participate in calculations and mutually verify the authenticity of their information to reach a consensus across the entire network. It can be said that blockchain technology is a specific database technology. So far, our big data is still in a very basic stage. Trusted blockchain data based on the consensus of the entire network is non-tamperable and full of history, which also enables the quality of the data to gain unprecedented strong trust endorsement. It also brings the development of database into a new era.
4. Data analysis: Blockchain ensures data security
Data analysis is the core of realizing data value. When conducting data analysis, how to effectively protect personal privacy and prevent core data leakage has become the primary consideration. For example, with the popularization of fingerprint data analysis applications and genetic data detection and analysis methods, more and more people are worried that once personal health data is leaked, it may lead to serious consequences. Blockchain technology can prevent such situations through multi-signature private keys, encryption technology, and secure multi-party computing technology. When the data is hashed and placed on the blockchain, digital signature technology is used to allow only authorized people to access the data. The private key ensures data privacy and can be shared with authorized research institutions. The data is uniformly stored on the decentralized blockchain, and data analysis can be performed without accessing the original data. This can not only protect the privacy of the data, but also safely provide it to global scientific research institutions and doctors for sharing. The basic health database will bring great convenience to solve sudden and difficult diseases in the future.
5. Data circulation: Blockchain protects data-related rights and interests
For individuals or institutions’ valuable data assets, blockchain can be used to register them, and transaction records are recognized and transparent by the entire network. , traceable, clear big data informationThe source, ownership, right of use and circulation path of assets are of great value to data asset transactions.
On the one hand, blockchain can eliminate the threat of intermediaries copying data and help establish a trustworthy data asset trading environment. Data is a very special commodity, which is essentially different from ordinary commodities. It mainly has characteristics such as unclear ownership and "it is owned after seeing it and copying it". This also determines that the transaction method using traditional commodity intermediaries cannot meet the needs of data. Share, exchange and trade. Because the intermediary center has the conditions and ability to copy and save all the data flowing through it, this is extremely unfair to the data producers. This threat cannot be eliminated by relying on promises alone, and the existence of this threat has also become a huge obstacle to the flow of data. Based on decentralized blockchain, it can eliminate the threat of data copying by intermediary centers and protect the legitimate rights and interests of data owners.
On the other hand, blockchain provides a traceable path and can effectively solve the problem of data verification. The blockchain jointly participates in the calculation and recording of data through multiple nodes participating in calculations in the network, and mutually verifies the validity of their information. It can not only prevent information counterfeiting, but also provide a traceable path. By stringing together the transaction information of each block, a complete list of transaction details is formed. The ins and outs of each transaction are very clear and transparent. In addition, when people have questions about the "value" of a certain block, they can easily review historical transaction records to determine whether the value is correct, and identify whether the value has been tampered with or recorded incorrectly.
Everything is guaranteed on the blockchain, and big data will naturally become more active.
The tokens of crowdfunding projects on the Biying China platform are all developed based on blockchain technology, and relevant information will be recorded on the blockchain.

❺ Understand the relationship between blockchain, big data, cloud computing, and Bitcoin

Blockchain is an tamper-proof, full-history database storage technology, a huge The block data collection contains the entire history of each transaction. With the rapid development of blockchain applications, the data scale will become larger and larger. Different business scenarios make the data integration of blockchain further expand the scale and enrichment of data. sex. However, what the blockchain provides is the integrity of the ledger, and the ability of data statistical analysis is relatively weak. Big data has massive data storage technology and flexible and efficient analysis technology, which will greatly enhance the value and use space of blockchain data.
Digital currency is a form of expression represented by blockchain 1.0, mainly Bitcoin; as a virtual currency system, the total amount of Bitcoin is limited by the network consensus agreement, and no individual or institution can Changes and modifications to the supply and transaction records, so after the Bitcoin network has been successfully running for many years, the blockchain, as the underlying technology that supports the operation of Bitcoin, is essentially an extremely clever distributed shared ledger and peer-to-peer value transmission technology. It will have a very large potential impact on finance and even all walks of life.
Blockchain and cloud computing, the research, development, and testing of blockchain technology involve multiple systems. Time and capital costs will hinder the development of blockchain technology.Breakthrough, software development based on blockchain technology is still a high-threshold job. Cloud computing services have the characteristics of resource elasticity, rapid adjustment, low cost, and high reliability, which can help small and medium-sized enterprises quickly and cost-effectively develop blockchain. Deployment, the integration of the two technologies will accelerate the maturity of blockchain technology and promote the rapid expansion of blockchain into the financial industry.

❻ Is blockchain a scam?

Blockchain technology itself is not a scam, but it does not rule out that some people use blockchain as a cover to commit scams. Several problems exist in blockchain: 1. The problem of excessive blockchain size. With the development of blockchain, the volume of blockchain data stored by nodes will become larger and larger, and the storage and computing burden will become heavier and heavier. Taking the Bitcoin blockchain as an example, the size of its complete data currently reaches about 71GB. If a user uses the Bitcoin Core client to synchronize data, it may not be possible to complete the synchronization for three days and three nights. Moreover, the data of the blockchain The volume is still increasing, which brings a great threshold to the operation of the Bitcoin Core client. 2. The problem of blockchain data confirmation time. The current blockchain system, especially the financial blockchain system, has the problem of long data confirmation time. Taking the Bitcoin blockchain as an example, the current confirmation time of a Bitcoin transaction takes about 10 minutes. In the case of 6 confirmations, you need to wait for about 1 hour. Of course, for credit card transactions, the confirmation time is 2 to 3 days. Bitcoin has made great progress, but it is still far away from the ideal state. 3. Dealing with the problem of transaction frequency The blockchain system faces the problem of too low transaction frequency. Qianyu Taking the Bitcoin blockchain as an example, the average size of each transaction is about 250 bytes. If the block size is limited to 1MB, the number of transactions that can be accommodated is 4,000. Calculated based on the rate of generating one block every 10 minutes, 144 blocks can be generated every day, which can accommodate 576,000 transactions. Divided by the number of seconds per day, 86,400, the Bitcoin blockchain can process a maximum of 6.67 transactions per second. Currently, the actual daily transaction volume on the Bitcoin blockchain is close to the system bottleneck (picture). If the expansion problem is not resolved, it may cause congestion and delays in a large number of transactions. Average number of transactions in a Bitcoin block (Source: Block Yuan) In comparison, Paypal's overall transaction count in the third quarter of 2013 was 729 million, with an average of 93.75 transactions per second. Information from the official website of VISA, the world's largest payment card, shows that VisaNet achieved a processing capacity of 47,000 transactions per second in a 2013 test. Compared with several major payment networks such as Alipay, the Bitcoin blockchain is more like a newborn baby in terms of transaction processing frequency. Of course, this was also an early deliberate design by Satoshi Nakamoto. The Bitcoin block size was limited to 1MB to avoid the malicious behavior of rogue miners and have a negative impact on people. The reason why the Bitcoin blockchain payment network The reason why it has grown to be worth billions of dollars today lies in its decentralization.4. The development of blockchain is restricted by the current system. On the one hand, the decentralized and autonomous characteristics of blockchain dilute the concept of national supervision and have an impact on the current system. For example, digital currencies represented by Bitcoin not only pose a challenge to the country's right to issue currency, but also affect the transmission effect of monetary policy, weakening the central bank's ability to regulate the economy, causing monetary authorities to remain cautious about the development of digital currencies. On the other hand, regulatory authorities also lack full understanding and expectations of this new technology, and the establishment of laws and systems may lag behind, resulting in a lack of necessary institutional norms and legal protection for economic activities related to the use of blockchain, which inadvertently increases reduce the risks of market entities. 5. The integration cost of blockchain technology and existing systems is relatively high. For any innovation, existing institutions must ensure that it can not only create economic benefits, but also comply with regulatory requirements and connect with traditional infrastructure. Especially when deploying a new basic system, the cost of time, manpower, and material resources is very large, and the resistance encountered within existing traditional organizations is also not small. Of course, the existence of problems cannot hinder the development of blockchain. The proposal and in-depth research of technologies such as simple payment verification, side chain, and lightning network protocols have provided ideas for solving the above problems.

❼ My husband wants to make a fortune by engaging in blockchain or something like that. Is this realistic?

Your husband has the same idea as me, because I lost 700,000 in blockchain. Later, because my wife stopped me, I started working again, but after working for two years, I found that the bank loan could not be repaid. Now my idea is to get into the blockchain next year, otherwise it will be impossible to pay off the debt in this life! Because for now, only blockchain and the Internet can turn over quickly!

I can tell you clearly that there are three types of people in the blockchain, one is speculating, one is mining, and the other is engaged in technology.

Currency speculation is the same as stock speculation. They are all money-making circles. If your husband has absolute capital to trade, he doesn’t need too much, tens of millions can trade, and there is no Moutai. The market capitalization is large, but this is very unlikely. Moreover, most of your husband is engaged in retailing, and the other half is engaged in mining.

The second type is to buy a mining machine for mining, which has a payback period and also follows the rise and fall of the currency. If one day this coin becomes worthless, you may lose money.

There are very few people doing the third type, and they are rarely seen online. They can actually put blockchain applications into practice. Blockchain has great prospects, and its characteristic is decentralization. Compared with traditional centralization, large-scale micro-nodes are used to replace high-voltage single-point clusters, which is what we often call the three stooges. Even Taobao dare not say that there will be no problems during Double Eleven. The peak will be busy, and the Alipay server was down two days ago, and requires high costs to maintain. These are the drawbacks of traditional central servers. Blockchain can solve this problem, load sharing, and giant The tasks are divided into very small tasks to be processed by the corresponding blocks. IfWhen the traffic peak of Double Eleven is reached, congratulations to the miners, they will make a fortune, haha, so there will inevitably be more mining machines to mine, that is, to provide computing power. If the computing power is higher than the peak, the miners bear the risks themselves. Let’s talk about the persistence issue. The amount of storage is getting larger and larger. Even GitHub is complaining. Domestic manufacturers are even more eager to cash in. I believe friends who have done it know that the biggest cost of a file server is not the storage space, but the network bandwidth and bandwidth costs. It is expensive, which is what top manufacturers like Alibaba and Tencent can afford. Blockchain is used for persistent storage. First of all, the network bandwidth problem is solved, and high-bandwidth transmission can be easily achieved. This is the advantage of p2p. High bandwidth can be combined with 5g. Technology, because the advantage of 5g is high bandwidth, they are a perfect match. There are a lot of uninformed self-media people on the Internet talking about the next generation of 5G. . They really don’t understand how to make short videos or something like that. 4G has done a good enough job in those things. 5G will give full play to the advantages of high speed and high bandwidth. To give a few simple examples: storage, blockchain storage can be used in the future. There may not be 64g, 128g, etc., only ram memory, you can specify the size by yourself and pay as you need. Because of the high speed and high bandwidth advantages of 5g, it can completely reach the reading speed of the machine. Second, high-reality VR, because of the distance factor of VR, needs to reach 4k to truly have a sense of immersion, cloud host, and then communicate with VR devices through 5G wireless, without the need for connecting cables and high-end graphics cards like the current HTC devices. , if the application allows, you can even run around the streets with VR glasses, and use virtual reality and augmented reality to simulate what you see based on the real situation, not like the current "elementary school version of ar". . There are many more that I won’t list one by one. In short, the prospects of blockchain are infinite, but its development is hindered due to certain political factors, because blockchain is anonymous, free to speak, and cannot be held accountable.

So if you are a technical person, he will not ask you to invest money without even explaining what blockchain is. If so, he is probably a liar. Coin speculation is not advisable, and mining is not recommended, but blockchain applications are the future. Money is not needed here, but more development talents are needed.

Maybe not many people will understand what I have said, but once you finish reading it, it proves that you are willing to listen. If you agree, it means that you are willing to accept new things and your thinking is not lagging behind. You are not a common person.

We should create the future together instead of being willing to be the dust of time. Live this life and leave some noise

You should be happy to have such a forward-thinking husband. Many people still don’t believe in the blockchain and think it is a scam or a pyramid scheme. At present, the country has Blockchain proves that it is a new economic model that will definitely become popular and develop rapidly in the future! You are not stopping, but investing heavily. This year is the last profit window. Next year, you may not be able to buy a single coin! ! !

To understand this issue, first let’s understand the concept of blockchain.

What is blockchain?

The rise of blockchain originated from the genius idea of ​​a mysterious geek, Satoshi Nakamoto, who invented the world’s first digital currency, Bitcoin. In recent years, the myth of Bitcoin’s wealth creation has made people familiar with blockchain. At the same time, various digital currencies have sprung up. The yearning for wealth has made people also flock to digital currencies.

However, the blockchain itself is not tailor-made for digital currency. Simply put, the blockchain is a decentralized database. To put it more simply, blockchain is a distributed ledger. This ledger does not have a fixed bookkeeper. Instead, when a transaction occurs, everyone keeps accounts together, regardless of whether it is their own transaction or not.

What we need to realize is that digital currency is just a way of blockchain application and does not create value in itself. More importantly, various digital currencies are currently not recognized in our country. , and the central bank is preparing to issue its own digital currency, so if it is investing in digital currency, I think it is not a wise choice.

In fact, blockchain as a technology should not be limited to digital currency, but should make a difference in fields such as finance, logistics, insurance, copyright, etc. However, currently blockchain There is still a long way to go in terms of applications in various fields.

If you want to get rich by relying on blockchain, you should think more about the application of blockchain in various fields instead of falling into the trap of digital currency.

I have only come into contact with blockchain knowledge this year, and my understanding must be too little. If you are not engaged in blockchain technology but engaged in blockchain digital currency investment, there is a high probability that you will still lose money in the end.

Judging from your statement, I think your husband must be engaged in blockchain digital currency investment. Even if you are lucky and make some money, you will still lose money in the end. Everyone is saying that Bitcoin has doubled. More than ten thousand times, the appeal of Bitcoin as a benchmark is too tempting.

There are currently thousands of digital currencies, 90% of which are scams and pyramid schemes. The rest have real blockchain technology but may not all be successful. In other words, these Some coins have no value. The only ones with value are mainstream coins such as Bitcoin. When the price of Bitcoin is too high, it can be used as an asset risk investment.

So what should you do?

First, you have to know that it is impossible for your husband not to invest in digital currencies, because he has deeply believed that this is an industry that can multiply thousands of times. Do you think you Is it possible for a person who is doing MLM to leave the MLM industry?

Second, blockchain technology is a good technology and a real futureTo revolutionize technology, digital currency is not a good currency.

Third, your husband likes blockchain. You can support him to learn about blockchain, but you must remember not to invest money in it. The money will be kept for you and you will not invest in it after one year. It will be late. He earns 10,000 per month. If you ask him to invest only 3,000 at most, it will be doubled by tens of thousands. In a few years, he will be able to earn thousands of times.

Fourth, find more news about MLM coins, scam coins, and runaway coins for him to read. There are too many on the Internet, and you can find them all in just one search.

At the same time, this is not the expectation and hope of many family members.

But time is like water, and years are fleeting. We cannot afford to wait for the aging of the elderly and the growth of children. Many men, who are the backbone of the family, are anxious, overworked, and occasionally make mistakes in judgment. Losing your temper is also normal. Long live understanding.

When it comes to getting rich, you should be anxious, but your strategic direction cannot be wrong.

At the same time, with the rectification of the financial industry, many pseudo-blockchain companies that were trying to sell things like dogs and cats have also been closed down one after another, resulting in individuals losing their jobs and going to jail.

The most reliable and ultimate application of blockchain can only be to serve the real economy in all walks of life like the Internet.

Many digital currencies that are touted by many people now, such as Bitcoin, are based on ultra-complex encryption technology, which would take hundreds of years to decrypt with current computer technology. In the future, when quantum computers come out, decrypting Bitcoin will only take a few seconds.

There are also some so-called digital currencies, which are actually carrying out illegal fund-raising, pyramid schemes and other illegal and criminal activities under the guise of blockchain.

The most important thing is that currency embodies national credit, which is supported by national sovereignty. Therefore, as a form of expression of money, digital currency cannot be separated from or fade away from this basic background.

With only a basic foundation of security experience and some management experience, it is definitely unrealistic to join the blockchain, a major trend industry, and do technology. You might as well study how to do security work specifically for the blockchain industry. By making the security pie for the blockchain industry market segment bigger and stronger, the benefits will be considerable. From this, realizing the dream of getting rich is just around the corner.

If it’s about feelings, I suggest divorce (I always advise divorce but not marriage).

If you are asking about making money, should your husband issue coins or buy coins?

If you buy coins, if nothing unexpected happens, you will still be in trouble, and the debt will make it worse.

If you are issuing coins, it is to trap other people’s money.

If you are lucky, you can make (cheating others) a lot of money.

If you are not lucky, just implementNow that I have financial freedom, after all, I can’t spend much money in prison...

The above, thank you.

.

I have been playing with digital currencies for five years, and I have also played with the capital market. At the end of 2017, I bought 20,000 to 30,000 digital currencies. Within a month, It rose to 200,000, but not much was made, and then slowly fell down in the next few months. Now I basically don’t play much. In the end, I still suffered a lot of losses. It is impossible to get rich when the market is not going well.

I think the country supports blockchain. Of course, digital currency is also a derivative of blockchain technology. In the next few years, blockchain can be said to be an outlet. It has nothing to do with digital currency. You can learn from it. Blockchain application technology, setting up a blockchain training class, studio, etc., of course, this is something you may do after accumulating a certain amount of blockchain knowledge. At the moment, you should learn first, and don’t think about it overnight. Rich, just like the Internet + online shopping a few years ago, it is a new thing, and interested friends can communicate with each other! !

If your husband can carefully read all the enthusiastic netizens’ suggestions and answers, I believe he will have a clear understanding and clear thinking.

Blockchain is nothing more than a synonym for the sharing economy, and there is nothing mysterious or mysterious about it. Investment can be done in moderation, and blockchain can be done because I am doing it. I haven’t invested a penny, but I have already made some extra money. I think blockchain is a good side job.

Personal opinions, for reference only.

It’s unrealistic. Maybe your husband doesn’t even know the true meaning of the blockchain

❽ What to do if the blockchain information is getting bigger and bigger

Over the past few years , with the vigorous development of Bitcoin, the number of Bitcoin transactions is increasing, and the size of a single block has a maximum limit of 1MB, so the free space in the block becomes smaller and smaller. As shown in the figure, the median block size doubled in 2015, growing rapidly from 292KB in January to 749KB in December.

Bitcoin block size

The issue of expansion received full attention and discussion in 2015. Around June 2015, many expansion plans were launched one after another, represented by BIP100, BIP101, BIP102, BIP109, BIP248 and other plans (Table X).

Although various plans have been proposed, they can basically be divided into two categories: the long-term rule-based faction and the short-term shelving faction. The long-term allocation is ideal and rule-based. It is finalized in one go and no more fussing. The typical representative is BIP101/103, which sets a growth rule and no longer adjusts. The short-term group believes that the future is unpredictable and fixed rules are too simple and violent to solve problems. They hope to set up a short-term and multi-year plan to avoid it for the time being and put it on hold until the future. The representative is BIP100. However, due to the complexity of the voting process, it was later simplified to BIP102/109, etc., while BIP248 has been postponed to 2020, and has simply doubled in recent years.

Since June 2015, after more than half a year of extensive and repeated discussions, the long-term rule-based faction has basically been completely defeated. After Pieter Wuille proposed Segregated Witness at the Bitcoin Hong Kong Scaling Conference in December 2015, the scaling issue has even been simplified to only an upgrade to 2MB, but it has been mired in debate about the implementation time.

A seemingly simple expansion technical issue has caused the Bitcoin community to spend more than half a year, hold several global technical conferences, and engage in countless private wars of words, but there is still no clear conclusion. The profound reason behind this is that raising the block limit value cannot truly solve the Bitcoin expansion problem. Scaling issue

In general, based on the understanding of the Bitcoin network, there are two divisions: clearing system and cash system.

Clearing system

The Bitcoin blockchain is a global, distributed, limited-capacity, expensive system. The value content of each transaction is different. When the block capacity is not enough, we should ensure that high-value transactions enter the block. High-value transactions have the willingness and ability to pay high enough network fees to obtain blocks with high enough priority.

As Bitcoin prospers, the number of transactions will become larger and larger. The limited block capacity will make it impossible for low-value transactions (such as sending 1 cent) to be included in the block because low-value transactions cannot be included in the block. May pay high network fees. Then the network degenerated into a clearing system, low-value transactions were driven out, and these transactions were replaced by third-party accounting systems.

Before the emergence of the Lightning Network, third-party accounting systems were mainly off-chain wallet providers. Users trust a third-party wallet platform and deposit Bitcoins into it. Transfers between users on the same platform only bring about changes in account balances and do not generate Bitcoin transactions.

Cash system

The cash system means that all transactions should enter the block. When the block capacity is not enough, the block size limit should be increased in time to expand the system. Transaction blocking may occur in the short term, but in the long run all transactions should be able to be added to the block. Everyone enjoys the tremendous convenience and advantages brought by the Bitcoin system.
