❶ bgh bit classic contract address

Hello, the bgh bit classic contract address is. Bitcoin Classic brings a sound currency to the world, fulfilling Bitcoin’s original purpose as “peer-to-peer electronic cash.” Bringing low-cost, reliable and reliable payment methods to enterprises and users. It has unlimited growth potential, global applications, innovative unlicensed payment methods, and decentralized development. The total circulation is 21 million pieces, which will never be issued again, of which 9 million pieces are in circulation. Bitcoin Classic continues Satoshi Nakamoto’s idea (block development can follow Moore’s Law), taking into account the current network conditions (especially China’s non-working firewall), increasing the original 1m block limit to 2m. Increase the total number of transactions the network can support.
Extended information:
1. The origin of Bitcoin Classic: The core team (mainly members of the blockstream company) insists that the 1m upper limit should not be modified. Gavin and others hope to expand the block capacity to increase the network before the block is seriously blocked. Supported transaction volume, Chinese mining pools believed that Gavin’s early solution had too high network requirements and was not suitable for domestic network conditions. Developer Jonathan came to China and conducted a series of on-site network performance tests based on block size. The test results show that the Chinese website supports blocks of 2-3m size without any problem. His test results were shared at a Hong Kong conference but ignored.
2. It is an optimized and upgraded version of the original Bitcoin chain, which is what we often call Bitcoin fork coins. Compared with the original Bitcoin chain, Bitcoin Classic increases transaction speed and reduces transaction fees. In terms of block size and capacity, Bit classic has also made great changes, expanding the unit block size, supporting each block size as a dynamic value, and increasing the original 1m block limit to 8m, which greatly increases the network The transaction volume that can be supported and the transactions in each block can be flexibly processed.
3. In addition, the generation speed of Bit Classic blocks has also been improved. One block is generated every minute. Each block rewards 50 BGH, and the reward is halved at the height of 2.1 million blocks. Bit Classic BGH’s innovations for Bitcoin: the block capacities for recording transaction information are different; Bitcoin’s block capacity is 1MB, while segwit in Bit Classic BGH has been deleted, and the 1m block size limit has been lifted. It can support the maximum block size of 8m and adhere to the link expansion route. It is a blockchain asset generated by Bitcoin and has higher stability and security. It can also support more transactions at a given time. The difficulty of the two algorithms is different. The upper limit of Bitcoin is 21 million. As more and more are mined, the algorithm becomes more and more difficult. Bit Classic BGH adopts a dynamic difficulty adjustment mode, and the production difficulty will be adjusted according to the computing power of the entire Bit Classic BGH network. The more nodes you add, the higher the difficulty and vice versa.
4. Initially, the block time set by Bitcoin was about 10 minutes. However, as the transaction volume of Bitcoin increased, a large number ofLarge-scale transactions are congested, transaction confirmation times become unpredictable, and transaction costs become unpredictable. Bitcoin Classic BGH may be able to solve the two major problems of Bitcoin’s unpredictable transaction costs and unpredictable transaction confirmation times. Overall, Bitcoin and bitclassic BGH are highly overlapping and can be called twin brothers. In addition, when bitclassic BGH was first born, it was also distributed to Bitcoin users based on "candy", so the original Bitcoin classic BGH users were also Bitcoin users, but the users who supported Bitcoin classic BGH GH advocated large blocks, while those who supported Bitcoin is an advocate of small blocks. In this era of constant innovation in blockchain technology, perhaps the innovator Bit Classic BGH will explain a new cryptocurrency to us. Larger block capacity, faster transfer speeds and lower handling fees will help Bit Classic BGH become a new cryptocurrency circulating globally.

❷ How to play the new game of forked coins

In September 2017, seven departments including the central bank jointly issued the "Announcement on Preventing Token Issuance Financing Risks". ICO (Initial Coin Offerings) is characterized as illegal public financing without approval, and is suspected of illegal sales of tokens, illegal issuance of securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal and criminal activities.

In 2017, ICOs became very popular relying on concepts such as "digital currency", "blockchain" and "smart contracts". However, financing activities can be started by just publishing a "white paper" by a team of several people, or even without a white paper. This method of operation creates great risks for investors, and the outside world has always been controversial about the legality of ICO. . In September last year, seven departments including the central bank gave a clear definition of ICO and stopped all types of token financing activities. The seven departments stated in the announcement that token issuance financing is essentially an act of illegal public financing without approval, and is suspected of illegal sales of tokens, illegal issuance of securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal and criminal activities.

However, after ICO was banned, a new method emerged in the currency circle - IFO. The so-called IFO refers to the issuance of forked currencies based on mainstream currencies such as Bitcoin and Ethereum. Based on the original blockchains of these mainstream currencies, another chain is split according to different rules to generate new digital currencies. People who hold mainstream currencies can obtain new coins after the fork during the IFO process, and IFO has become a new means of financing virtual currencies.

On August 1, 2017, the birth of BCH marked the first fork coin in the currency circle. The size of the Bitcoin block is only 1M, and the smaller the block, the smaller the capacity, and the slower Bitcoin transactions will be. In order to solve the problem of Bitcoin block congestion, the BCH blockchain successfully separated from the main chain at block 478559, resulting in a new cryptocurrency. The default block size is 8M, and it can beTo achieve dynamic adjustment of block capacity. At the same time, people who originally held Bitcoin can obtain BCH for free at a 1:1 ratio.

Since its birth, there have been mixed opinions in the industry as to whether BCH is a new branch of Bitcoin or another “altcoin”. However, after the price of BCH experienced several ups and downs, it began to gradually develop steadily. As of 20:30 pm on February 26, Huobi data shows that the price of BCH reached 8058.8CNY (RMB), and the price of BTC (Bitcoin) was 67558.69CNY.

Following the success of the BCH fork, more and more new virtual currencies have been created through IFO, such as BTG (Bitcoin Gold), BCD (Bitcoin Diamond), SBTC (Super Bitcoin) etc. Chen Yunfeng believes that according to relevant technical explanations, some forked coins are upgrades or improvements to the original technology. If it is a fork at this level, it is difficult to say that it has no value, and the regulatory level has repeatedly warned about the risks of virtual currency investment. In such cases, the investment value should be judged by the investors themselves.

Shi Qingwei, founder of Shared Finance, said that IFO is a new method that has emerged in the currency circle in the past two months. Most of the projects generated by IFO have no investment value. Some IFO issuers believe that they are not raising funds through ICO, but are forks of mainstream currencies such as Bitcoin and Ethereum, which have a large number of users. After users get the forked coins, they usually ask to join the transaction, and then the issuer of IFO will make huge profits from the number of previously mined forked coins. He further stated that most of the forked coins generated by IFOs have no investment value and are even more risky than ICO investments.

"Pre-mining" forked coins may involve fraud risks

So, how does IFO make money? "Daily Economic News" reporters discovered that miners use technical means to develop forked coins in the Bitcoin block, and then distribute the developed forked coins to Bitcoin holders in proportion, and gain value in transaction circulation, part of which Trading and circulation will also be carried out through digital asset exchanges. It is worth noting that most forked coins will be "pre-mined" before they are officially released. The pre-mined forked coins are equivalent to being obtained for free, so the founders of the forked coins will be able to easily earn profits. In the market, some people believe that IFO, known as “pre-mining”, is actually a more naked money-making game through token issuance.

On November 15, 2017, the well-known super bitcoin team in China announced that it would implement a fork at the 498888th height of the Bitcoin blockchain on December 17 and start zero-knowledge on BTC. Prove, support Turing-complete smart contracts and other technical experiments, and expand its block to 8MB. It will also launch smart contracts in early March 2018 to increase BTC scalability, and launch zero-knowledge proofs at the end of May 2018. At the end of November this year, dynamic checkpoints were removed to achieve fully decentralized mining. If the fork succeeds, it will produceThe new split coin - SBTC, will be given away one-to-one to the original holders of Bitcoin. The total amount is 21.21 million, of which 210,000 are pre-mined for the fork, which are managed by the fork team foundation and are mainly used to encourage early stage Developers invest in ecological construction and foundation operations.

Famous economist Song Qinghui said that due to the lack of regulatory policies and the extremely low threshold for user participation, IFO itself may be suspected of illegal sales of tokens, illegal issuance of securities, illegal fund-raising, financial fraud, etc. Many new virtual currencies born through IFO have almost no value. There may be deception and fraud, and investors need to pay enough attention.

Shi Qingwei analyzed that: on the one hand, IFO will cause great divisions in the community; on the other hand, the people who issue IFO are basically investors, and there are few who actually do IFO projects in a down-to-earth manner. Because people do not have strong execution and values, it is difficult to implement IFO projects. To put it bluntly, some IFO projects are short of money and will not be carried out after cashing out. There are no particularly big risks. Just intensify market acquisitions and cut leeks. The most typical risk is fraud risk, and the other is market operation risk. Some investors have been trapped in the IFO project.

In the view of Zhang Yexia, a senior researcher at Yingcan Consulting, first of all, IFO financing activities are not clearly defined in Chinese law and there is a risk of being prohibited; secondly, there is the risk of fraud. With the development of the IFO concept, With the rise of the currency, it is easy to attract criminals to use concepts such as "mainstream currency forks" and "blockchain technology" to attract investors, but in fact there is no so-called token issuance and technology research; the third is technical risk. Currently, Bitcoin on the market The technologies and standards for the forks of mainstream currencies such as Bitcoin and Ethereum are different. They do not have the same technical standards and their technical levels are also different. Technical security risks cannot be ignored.

Chen Yunfeng believes that for financing activities in the name of IFO, the forked coins issued by it have no actual application scenarios. Investors obtain the forked coins only through the digital currency trading market. Obtaining value-added income, this form of financing activity has not yet been clearly defined in law and is subject to the introduction of specific regulations by relevant departments.

Hong Shuning, chief researcher of the Blockchain Laboratory of Suning Financial Research Institute, believes that the risks of IFO are reflected in the following aspects: first, changing the protocol without careful consideration may have serious loopholes; second, rushing The released software will inevitably have a large number of bugs; third, each IFO will divert some miners, causing fluctuations in the smoothness of Bitcoin transactions; fourth, due to the low acceptance of forked coins, the price fluctuations may far exceed that of Bitcoin. Bad for investors.

Hong Shuning also said that in the true sense, IFO should not have pre-mining behavior, because this goes against the original intention of Bitcoin development, fairness and freedom. In fact, IFO is a disguised financing method like ICO. Teams that need to pre-mine profits should issue their own digital currency instead of using the banner of IFO.

None are legal.

❸ How to explain blockchain in a popular way

“Blockchain technology is considered to be the next generation of disruptive core technology after steam engines, electricity, and the Internet. If the steam engine unleashes People's productivity, electricity solves people's basic living needs, and the Internet has completely changed the way information is transmitted. Then the blockchain, as a machine that builds trust, will likely completely change the way value is transmitted in the entire human society."

I have just come into contact with the blockchain. There are too many basic knowledge that need to be understood and known. Don’t worry, today I will popularize this knowledge for you. Today let’s take a look at what public chains, private chains, alliance chains and side chains are.

❹ How much resources does the Bitcoin wallet occupy on the computer? The C drive is full, but the file cannot be found

The current Bitcoin blockchain The data capacity continues to grow and is now about 10G. When many friends installed the system, the C drive was not set to a large size. Are you worried that the C drive will explode one day? Learn how to do data migration with me now. (You need to close the Bitcoin client first)

1. Find the bitcoin data folder;

XP---C:\Documents and Settings\username\Application Data\Bitcoin

vista,win7---C:\Users\username\AppData\Roaming\Bitcoin
(Note: AppData is hidden, set to show hidden files.)

2. Cut this Bitcoin folder to another drive with larger space, such as e drive;

3. Edit the Bitcoin shortcut on the desktop and copy the following line to "Target ” column, save:

"C:\Program Files\Bitcoin\bitcoin-qt.exe" -datadir=e:\Bitcoin

Now, double-click the desktop The Bitcoin shortcut on the client will start, and your C drive will be saved and the space will be successfully released.

❺ Is Bitcoin stored by a computer?

1. Bitcoin file format
Bitcoins are stored in a program or client and are controlled by a private key.
2.ComparedBitcoin GB or MB or KB

After the complete Bitcoin client is synchronized, it currently has a volume of 23G. Because of its large size, there are currently online wallets or lightweight clients available for use.

3. Is the size of each Bitcoin the same?
Yes.

❻ What is the expansion of Bitcoin and why it needs to be expanded

The size of each block is one megabyte, which can probably accommodate If you look at the information of more than a thousand transactions on a Bitcoin blockchain browser, you will find that each block is about one trillion, which has reached the upper limit of block capacity. If Bitcoin There are more and more transfers on the currency network, and many transactions will not be packaged and confirmed in the first block after the transaction occurs. It may take several blocks or longer. Bitcoin has encountered several dust attacks in its history. Among them, many traders created a large number of small transfers on exchanges (Bihui). Dust attacks are caused by someone. A large number of small-amount transfers are created, resulting in a large number of transactions to be confirmed in the network, causing normal transfers to not be confirmed and the confirmation time to be delayed, affecting the normal operation of the network.
Many traders wait two days or more for their transactions to be confirmed. Although the dust attack is a very extreme example, looking at the current Bitcoin network, the normal transfer volume has far exceeded what he can The maximum capacity that can be tolerated, each block size is now one trillion, so expanding the Bitcoin block capacity and breaking through the existing one trillion size limit is called expansion.

❼Bitcoin Cash block size

The block size of Bitcoin Cash is approximately 1M.
The blocks of Bitcoin Cash are about 1MB, and the size of the most recent block is only 57KB. Hard fork expansion is actually almost meaningless.
Like in the Bitcoin network, the block size is limited to 1M, and a block is generated every ten minutes. The Bitcoin network can support only 7 transactions per second in concurrency.

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

Over the past few years, with the vigorous development of Bitcoin, the number of Bitcoin transactions has increased, and the size of a single block has There is 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: long-term rule-based and short-termSet up 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 and so on, 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 prevent low-value transactions (such as sending 1 cent) from entering 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.

❾ 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 with 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 per Bitcoin block (Source: Block Yuan) In comparison, Paypal's overall number of transactions 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 problems with the use of blockchain technology.Chain-related economic activities lack necessary institutional regulations and legal protection, which invisibly increases 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 chains, and lightning network protocols have provided ideas for solving the above problems.

❿ Why does the Bitcoin block size need to be maintained at 1M?

Maintaining the size of the Bitcoin blockchain at 1M is the Bitcoin Core team’s own wish. It is not necessary. It must be maintained at 1M. Module key 1M.
When Bitcoin was first born, Satoshi Nakamoto did not set the blockchain size to 1M, but at that time Bitcoin transactions were very few and there was no congestion problem. This was also done to prevent the Bitcoin network from being attacked. Set the blockchain size to 1M. At the end of 2013, the congestion problem of Bitcoin was already very obvious, so capacity expansion was gradually put on the agenda and became a consensus, but there was no consensus on how to expand the capacity.
The reason why Core insists on keeping 1m unchanged may be selfish. It regards Bitcoin as its own child and can do whatever it wants. However, there is very loud opposition from the Bitcoin community. Because it rejects the Hong Kong Consensus it signed, it is also unpopular at home. Domestic support is more for large blocks, and the BU solution is also one of the solutions sought after by Kema Oak.
