BTC bifurcated LBTC plastic doll
About bitcoin, the news is flying all over the world these two days
specifically, a foundation called BTN foundation announced that it has set up a bitcoin bifurcated development team to launch a new bitcoin bifurcated BTN. Now its official website is online, which is called btn.kim. Two days later, bitgo, another bitcoin development team, announced that it would fork out from bitcoin. Its name is BTF, which literally means "bitcoin faith"
according to Yao yuan, a well-known bitcoin columnist, bitcoin will "have 10 children" in December, and will at least bifurcate out of 10 "children" such as BCX, SBTC and LBTC
as soon as these things happened, the bitcoin market began to fluctuate again, some investors blew up, and all kinds of rumors came out: why so many forks? Is bitcoin out of order
in fact, the bifurcating of bitcoin is far more complicated than what it shows. If we don't explain its historical background clearly, we really can't understand what happened
< b > the origin of bifurcations: the origin of the bifurcations of bitcoin has existed. The so-called bifurcations refer to the accounting differences caused by different underlying protocols. According to Xue Hongyan, director of the Internet financial center of Suning Financial Research Institute, bitcoin is jointly maintained by a number of point-to-point decentralized nodes. The orderly operation of the whole system depends on the consensus of all nodes, that is, there is a set of recognized standards for key issues such as which transactions are acceptable and which nodes have accounting rights. This set of standards is deployed in the underlying protocol of blockchain and implemented automatically
but nodes are operated by people after all, which is the so-called "miner", but everything operated by people will be different. For example, the miners of some nodes go online every day, while the miners of some nodes go online occasionally; Some nodes are in the eastern hemisphere, some nodes are in the Western Hemisphere... In a word, e to various reasons, over time, bitcoin has different underlying protocols in different nodes
if different versions of underlying protocols are running in a node, different standards will appear, which will result in bifurcation. If the nodes can deal with these version differences and finally form a unified standard, the bifurcation will eventually disappear, which is called soft bifurcation. If the difference cannot be eliminated, when some nodes continue to run different versions of the protocol, the bifurcation will continue, which is called hard bifurcation
it's easy to solve the problem of soft bifurcation, that is, if the account book is wrong, just modify it. Hard bifurcations are not easy to solve. No one thinks he is wrong and explains them according to his own standards. In the end, he can only go his own way and keep his own account. At present, bitcoin bifurcation refers to hard bifurcation
< b > the first bifurcations: the first hard bifurcations of bitcoin technology upgrade are purely technical reasons. The settlement performance of bitcoin itself is limited. According to the original technical agreement, bitcoin can only support up to seven settlements per second. This was not a problem in the early days. With the fire of bitcoin, more and more people flocked in, and the settlement became more frequent than ever. At this time, the original technology was not enough
therefore, in the middle of 2017, some miners proposed new technology agreements, but the other miners did not agree with them. Eventually, both sides held one end and ran their own underlying agreements, which was the first bifurcation in the history of bitcoin
However, with the development of bitcoin trading means, speculators graally regard the bifurcation as a means of money collection, which leads to a great change in the nature of the current bifurcationthe principle is that each bifurcation is essentially equivalent to the issue of a new digital currency, which is linked to bitcoin. The target audience is larger than the general ICO, and it is easier to be accepted by ordinary users than issuing a new digital currency directly
because the team that creates this kind of bifurcation takes the lead, it is very easy to control the transaction of the new currency, especially in the early stage, and it only needs a small cost to control the price trend of the whole currency. This leaves a lot of room for speculation. The forked team only needs to make the new currency accepted by the users, and then it can artificially raise the price to a sky high price. After the real users come in, they can sell all the money they hoard, and get high profits out of thin air
on October 25 this year, a domestic team forked out bitcoin gold (BTG). Two days before the forking, Jiang Zhuoer, CEO of leibitchi, denounced the forking as money looping: "Liao Xiang, founder of BTG, had g 200000 BTG coins in advance before the forking, and wanted to convert them into 20000 bitcoins, looping 80 million yuan."
The advantage of bifurcations can be seen, so that the word "bifurcations create value" has become popular in the field of currency speculation. For this reason, a new word "IFO" - first token issue has been derivedHe Sheng, a well-known financial blogger, once told the media that most of the so-called IFO may evolve into the operation of collecting money by harvesting leeks. "Many previous ICOS are doing IFO, and ICO needs to write a white paper and go to the stock exchange to gain market recognition, while IFO does not even need to write a white paper."
this also explains why bitcoin is becoming more and more profitable. To put it bluntly, everyone wants Nakamoto
Can< b > not bifurcate
whether it's Hong shuning of Suning finance, or Mike & Chen, CEO of bitgo, a bitcoin wallet software provider and one of the project leaders of segwit2x; Mike belshe, the instry actually refuses this bifurcation of bitcoin. In fact, real blockchain practitioners have always hated speculation. At present, the leading enterprises in the domestic blockchain instry have clearly expressed their opposition to the overflow of bitcoin bifurcation. For example, when Xunlei launched the first popular blockchain project in China, its CEO Chen Lei said in an interview: "Xunlei opposes all speculative activities using blockchain, so it is definitely against bitcoin for the purpose of speculation and leek cutting arbitrage."
However, to solve this problem, it is not enough to have an attitude alone, but to have specific means. The best way is not to let bitcoin bifurcatethis is difficult to achieve. Bitcoin's own technology is a relatively primitive blockchain technology with limited computing power. It can barely cope with the previous transaction scale. In view of the current situation of bitcoin fire, it is difficult to support. So sooner or later bitcoin will have to solve the problem of its own computing power
but there is no hope at all. With the innovation of blockchain technology, there will always be some new ways. For example, the shared computing proposed by Xunlei can effectively improve the total amount of computing power and rece the cost per unit of computing power without changing the existing hardware facilities. If bitcoin is combined with shared computing, it can effectively solve the problem of bitcoin's computing power limit without new bifurcation
secondly, the bifurcations for the purpose of cutting Chinese chives can be supervised by means of supervision. For example, compared with the real name system of special currency wallet, the real name system of transactions can effectively prevent the risk of Financial Bureau. At present, the real name system has been implemented in some blockchain projects, and has achieved good results. For example, Xunlei's blockchain is the first blockchain application to introce the real name system in China, which basically eliminates the hidden danger of malicious speculation
in a word, there is a way. It depends on whether bitcoin players accept it or not, and there is a process to implement it. It takes time. Therefore, at this stage, it is better for us to stay away from the bifurcations of bitcoin in various names
Q: What is bitcoin bifurcation and why
A: the reason why bitcoin bifurcates is that the underlying technology of bitcoin is blockchain. Some people begin to think that bitcoin's block capacity is too small and there are always congestion. So they ask for bitcoin's upgrade and expansion. Some people think that bitcoin's function is too single and its future development is not optimistic, So these people ask bitcoin to have the function of building DAPP (decentralized application), and some support it, while others oppose it. This kind of divergence can be understood as the bifurcation of bitcoin
Q: the classification of bitcoin bifurcation
A: there are two kinds of bifurcations of bitcoin, one is soft bifurcations, the other is hard bifurcations, so what is soft bifurcations
Q: the formation principle of soft bifurcation
A: soft fork refers to optimizing and modifying bugs in the original bitcoin network to improve the capacity of the block, such as 2m, 4m or 8m, 16m. The segwit lightning network is the mainstream solution, which is equivalent to a traffic jam on the main road, and the development team will build an auxiliary road to help the main road to divert congestion
this is a mild solution, which can make the original bitcoin network compatible with the network after soft bifurcation, and the main transaction of bitcoin is still on the main chain
Q: disadvantages of soft bifurcation
A: of course, there are disadvantages of soft bifurcation, that is, it can only solve the temporary congestion problem, and after the implementation of soft bifurcation, it can only keep the network unobstructed for a few years. In the future, it needs continuous expansion, which has an impact on the stability of the system
Q: what is hard bifurcation and its formation principle
A: another solution is hard fork, which means to upgrade the bitcoin system again, change the height of the block completely in the form of code, and take bitcoin unlimited as the mainstream solution. Generally speaking, it is equivalent to a traffic jam on the main road. We directly abandon this road and find a place to build a three-dimensional transportation hub on the ground and underground. All new cars use this transportation system, which changes the block size of the bitcoin network and optimizes the processing speed of the network
Q: what are the disadvantages of hard bifurcation
A: but hard bifurcations also have disadvantages, that is, they are not compatible with the original bitcoin system, which requires all people in the bitcoin network to support hard bifurcations. If some people do not support hard bifurcations, there will be two versions of bitcoin network, which will proce two bitcoins. The blockchains of the two bitcoins form a competitive relationship, This kind of internal friction will lead to greater price volatility and uncertainty of bitcoin's future situation
Q: a classic case of bitcoin bifurcation
A: Eth and etc are typical cases of hard bifurcation. The Dao project is a crowdfunding project initiated by slock.it, a blockchain Internet of things company. It was officially released in May 2016. As of June of that year, the Dao project has raised more than $160 million. It wasn't long before the Dao project was targeted by hackers. Because of the huge loopholes in the smart contract, the Dao project was transferred to ether coin with a market value of 50 million US dollars
in order to recover the assets of many investors and stop the panic, vitalik buterin, the founder of Ethereum, finally proposed the idea of hard bifurcation, and finally completed the hard bifurcation in block 1920000 of Ethereum through a majority vote of the community, rolling back all the Ethereum coins occupied by hackers
even though Ethereum hard bifurcates into two chains, some people who believe in the tamper proof property of blockchain still stay on the original chain of Ethereum classic. Today, Ethereum (ETH) and Ethereum classic (etc) are ranked in the top 20 in the global cryptocurrency market value, which is one of the reasons why they are regarded as classic cases in the field of hard bifurcations
Q: the difference and influence between soft bifurcation and hard bifurcation
A: for users, soft forking will not proce new bitcoin currency. They only need to understand the transaction mode and K-line characteristics of bitcoin. They only need a mainstream wallet of bitcoin
hard bifurcation will generate new currencies, and there may be more than one new currency. Once the core code of bitcoin is modified and the core code of bitcoin is reconstructed, there may be a second time for the first time, and btc1 and btc23456789 may all happen. Users will be confused. Which kind of coin would be better for me to trade? What kind of bitcoin do I use to pay for a large circulation range? In short, users with dyschooia will crash. Moreover, users need to download wallets of different hard bifurcated systems, which brings complex operation to save and pay bitcoin
however, correspondingly, the user's right to choose has also increased. You can choose the bitcoin code developed by the development team you like and trust. When the bifurcations of bitcoin are not clear, when the soft bifurcations start to activate and the computing power starts to vote, the best way for users to deal with it is to wait and see. Don't recharge and extract bitcoin in the process of bifurcation
in addition, soft fork will change the settlement mode of bitcoin all nodes, and some small settlement will be confirmed by the third party node, namely settlement channel. The settlement channel may incur part of the service charge. Similar to the role and business model of UnionPay
what is bitcoin bifurcation? The difference and influence of soft bifurcation and hard bifurcation
In the discussion of blockchain, bitcoin and other digital currencies, we often hear the word "bifurcation". So what is bifurcation? What is the effect of bifurcation
blockchain
before talking about bifurcation, popularize a little knowledge of blockchain, so as to help us understand what bifurcation is more easily (if you don't have any concept of blockchain, please read my previous articles, which are all popular words to help you understand what blockchain is)
blockchain, as the name suggests, is a chain composed of blocks. Of course, this kind of chain is just a figurative metaphor. To put it bluntly, data blocks are connected orderly. In bitcoin, the transaction records of bitcoin are stored in the block. The size of the block and the space occupied by the transaction records determine how many transactions can be stored in a block. These transaction records are packaged into blocks, and then the blocks are connected one by one to form a blockchain
We know that bitcoin software, like other software, needs to be updated and modified regularly in order to make it better. So a new version will appear, but not everyone will download the new version, so one miner will run the old version, and some will run the new version. If the old and new versions are not compatible, the blockchain will bifurcate. Because there may be differences between the version blocks and the old version blocks, they cannot be connected to the same blockchain, so there will be two or even more chains, which is called bifurcation
soft forking
soft forking refers to that when the new consensus rules are released, nodes that have not been upgraded will proce illegal blocks because they do not know the new consensus rules, resulting in temporary forking. This kind of bifurcation will be graally repaired with the upgrading of nodes
hard fork
hard fork refers to the permanent divergence of the blockchain. After the release of the new consensus rules, some nodes that have not been upgraded cannot verify the blocks proced by the upgraded nodes, and usually hard fork occurs. Therefore, in the field of digital currency, hard bifurcation often leads to the emergence of new currencies. For example, the hard bifurcation of Ethereum led to the emergence of eth
What is bifurcation? What is bitcoin bifurcationdpos mechanism
in recent years, e to the resource waste of pow, unstable block output, and the existence of computing power attack, although POW is recognized as the most widely used and secure consensus mechanism, there is still a great risk of being attacked for the block chain with insufficient computing power in the whole network. More and more consensus mechanisms are proposed to be used in blockchain projects for trial and experiment. Dpos is one of the mainstream consensus mechanisms, and LBTC has adopted this mechanism. Dpos ensures that the voting right is in the hands of the coin holder, so the coin holder will be able to choose whether to pass the motion by voting, so as to determine the development direction of the project. At the same time, it also means that the development direction of the project depends on the hands of the people who care about the project itself, and the power of wisdom will promote the better development of the project. At the same time, the advantages of dpos mechanism are that there is no computing power attack, strictly abide by the time block and save resources
dpos advantages of LBTC
the dpos mechanism of LBTC also has its own characteristics: the number of nodes of LBTC is 101, compared with 21 or 51 nodes, the coin holder can vote for 51 nodes at most once in the wallet of LBTC, which further reces the risk of centralization; LBTC can output blocks stably in 3 seconds, and the block size of 2m ensures that LBTC is 400 times more efficient than bitcoin, and the transaction speed can reach more than 2000 transactions per second; The most important difference between LBTC and other projects is that LBTC's dpos mechanism has the rule of irreversible block. When the number of block agents reaches 90% or more in one round, or when the number of block agents exceeds 70%, the first block in the previous round can be considered as irreversible, so as to prevent bifurcation
LBTC's defense measures
in addition to dpos consensus mechanism, LBTC's technical level has other highlights
first of all, LBTC can prevent [replay attack]. What is a replay attack? Each bitcoin account will have a corresponding number of lbtcs based on its bitcoin balance. If the address, private key, algorithm, etc. on each chain are the same, and the transaction format is the same, the transaction initiated on one blockchain can be put on another blockchain for rebroadcasting, and may also be confirmed. This is the "replay attack.". In short, when a user transfers LBTC, BTC may also be transferred at the same time. LBTC modifies the hash algorithm in transaction signature. In the hash algorithm, "LBTC" field is added to LBTC. The hash generated by LBTC and BTC will be different. LBTC and bitcoin do not recognize each other's transactions, so as to prevent replay attacks
secondly, to prevent [forged mining]. There are no concepts of voting and balance in bitcoin transaction. In order to maximize the stability of LBTC, a new output composed of OP return is added in coinbase transaction. Op-return data is composed of three fields: publickey, time and sign (time). Time represents the timeliness of transaction. Publickey verifies sign (time), which is the principle of asymmetric encryption algorithm to prevent forgery and mining. LBTC has 101 nodes. Assuming that the attacker has 30 nodes, if the remaining 71 nodes are forged, other nodes can mistakenly think that the attacker's chain is the longest and block out. This is a forgery mining attack
thirdly, prevent [double flower attack]. Double spending attack is a money spent twice, it can also be called double payment attack. For example, BTG, which has attracted wide attention before, recently suffered 51% attacks. A malicious miner obtained at least 51% of the computing power of the BTG network, temporarily controlled the BTG blockchain, quickly raised money after recharging the exchange, then reversed the block, and successfully implemented Shuanghua. Due to the irreversible block mentioned above, when the transaction of LBTC block is confirmed, it is impossible to roll back, so as to prevent the double flower attack
Fourth, multithreading. In LBTC's transaction consistency and legitimacy check, the data that can be merged and integrated are merged and executed by multi thread, which greatly improves the transaction efficiency and enhances the performance of LBTC
code logic of LBTC
in addition, in terms of code logic, LBTC is divided into protocol layer, consensus layer and application layer. When it is necessary to transfer value, the transaction is completed through the protocol layer link and consensus layer. This process can not only be used as the exchange of value, but also as the value intermediary in the tripartite connection. The application layer is mainly based on smart contract. In the future, LBTC will realize the function of gateway based on smart contract. The payment gateway implements asset issuance, asset transaction, currency exchange, chain interaction and so on
that's why LBTC can say that it wants to do global value internet protocol. Through the payment gateway, it can exchange any currency, not only between currencies, but also between legal currency and digital currency. Isn't that very convenient? One click conversion is to buy eth with vnd and transfer it to her British cousin in the distance. She dislikes it and immediately changes it to EOS. After one second, it is changed to pound sterling. There is no need for extra conversion steps. It's good to get it in one step? Such an analysis, in fact, from the technical code level analysis of LBTC is quite reliable. However, compared with those experts, Xiaobian won't deceive you. Whether LBTC can realize decentralized value Internet Protocol in the future, focusing on code will be a more intuitive way GitHub of LBTC: https://github.com/lbtcio/lbtc-core
how to use gateway
next, we talk about the specific implementation of the gateway's "conversion and circulation", which can be roughly divided into three kinds:
first, after the LBTC system has built the gateway technology, with the gateway as the bridge, user a can convert any currency into LBTC, and then send it to any user B who wants to send it, while user B can convert LBTC into any currency he needs, Does this sound like what you usually do on the exchange? I think this is one of the reasons why LBTC proposes to be a "decentralized exchange"
Second, user a can deposit the funds in the gateway trusted by user B and transfer them to user B through the gateway
thirdly, LBTC will provide the function of "any user can issue token" in the early stage of gateway construction. Therefore, in the LBTC system, if user a has a good reputation, is recognized by everyone, and issues its own a token (of course, it should include the asset chain realized by asset mortgage), a can use its own a token for user B's currency exchange. After that, user a can redeem the a token exchanged to B. A is the gateway role in the transaction process
in the process mentioned above, the functions of asset issuance, asset transaction, currency exchange and chain interaction are realized respectively
the gateway is similar to the function of a bank, which can mainly solve the problem of cross-border transfer. With the high TPS and low handling charge of LBTC, it will be very convenient to realize cross-border transfer. For example, if you need to remit money from China to the U.S., you need to remit RMB to China's LBTC gateway, and then the U.S. gateway will receive the LBTC from China's gateway, convert it into U.S. dollars, and forward it to the U.S. account. In the above gateway system, it can be concluded that both payment parties do not need to join the network, just need to trust the gateway
although the gateway solves the problems of slow speed and high handling charge of traditional transfer payment, it also faces new problems
then there is a problem
in addition to the standard institutions or project parties invited by LBTC can become gateways, ordinary users can buy and sell with each other (in fact, this kind of behavior is more inclined to loan, if it is only the business between acquaintances, it will form a small independent network), How to prove that gateway is a trustworthy organization or indivial
how to extend the gateway of LBTC to cooperate with large organizations is obviously a problem for the team. Ripple has developed more mature. At present, it has cooperated with MUFG in Japan, Westpac in Australia and Standard Chartered Bank in the UK. With ripple, star currency and other payment digital currencies in front, LBTC needs to have more characteristics if it wants to go out of its own route. This can be expected in the later intelligent contract route planning
however, ripple is also accused of being too centralized because of its distribution mode. LBTC has 101 nodes because of its dpos mechanism, and because it is a bifurcated coin, it will be distributed to bitcoin holders 1:1 when it is issued. This can be said to be the inherent advantage of LBTC - it has wide dispersion. If it can be supported and recognized by the public in the future, it can reach a consensus, Then it will form a congenital advantage of wide distribution
in addition, how can we prove that assets really exist in reality and can be used as collateral in the process of asset chain? In addition to large-scale institutions such as banks, small-scale network also has its inevitability. The proof of assets on the asset chain is a very important part. If it is not regulated and certified, it is very likely that the gateway will run away or false gateway will occur. Although the gateway is exemplified as "Taobao" platform, in theory, the platform can not manage the business content, but the platform has supervision on the quality of goods, otherwise it will cause confusion
decentralized exchanges
let's go back to the first point and talk about my ideas on decentralized exchanges. At present, mines and centralized exchanges are the protagonists in the early development of blockchain. With the rise of more and more exchanges, centralized exchanges fall into manipulation scandals and so on, which bring room for the growth of decentralized exchanges. Decentralized transaction is very likely to bring value to the field of blockchain and become the real protagonist in the era of blockchain. With gateway technology, LBTC can realize decentralized exchange. In the decentralized exchange of LBTC, the user's own currency will be kept by himself, which prevents the possibility of losing the currency in the centralized exchange. At the same time, it can also prevent the opaque system transactions, operational and technical risks. According to the previous gateway interview, LBTC will also work with reliable project parties to put on the stock exchange for the benefit of all community members. Generally speaking, LBTC's development route is relatively clear, and its goal in the field of payment is also very clear. Hold on, partners, the future is promising!
LBTC was highly forked in block 499999 of bitcoin on December 23, 2017, with a circulation of 21 million, and does not support segwit.
as you can understand it, it's like the stock of these technology service providers. As these technologies become more and more widely used, these virtual coins will become more and more valuable
bitcoin, which appeared in 2009, is the first kind of virtual currency in the world. It is also the first time that it has applied the blockchain technology which is popular all over the world
after bitcoin, there are many imitators in the market. They either improved on the basis of bitcoin, or put forward more grand technical ideas than bitcoin. Virtual currency, which is common in other markets and considered as "regular army" by instry insiders, is collectively referred to as competitive currency. Together with bitcoin, it forms the whole digital currency market, with a total market value of nearly 100 billion US dollars
there are thousands of virtual currencies in the market, most of which are risky; In addition, there are many MLM coins that are simply for the purpose of deceiving people< In order to help you avoid being cheated, the following is a brief introction to the main "regular army":
1. Bitcoin (BTC)
bitcoin is the first virtual currency in the world, with a total of 21 million. At present, more than 16 million bitcoins have been "g up", with a total market value of about US $45 billion, equivalent to half of the total market value of all virtual coins. It is well deserved to be the number one in the coin circle
bitcoin has been accepted as payment currency by hundreds of thousands of businesses around the world; In addition, bitcoin has also become a common money raising currency in various blockchain technology startups. Therefore, with the increasing demand for bitcoin, the value of bitcoin is likely to grow in the long run
2. Eth is regarded as "bitcoin version 2.0" and is the most likely competitor to surpass the market value of bitcoin. Some time ago, the market value of bitcoin was close to that of bitcoin. However, e to the price rection in the recent month, the market value of bitcoin is only about half of that of bitcoin
Ethernet coin was born in the summer of 2014. It is issued on the Ethereum blockchain, which is different from bitcoin. Ethereum blockchain is a decentralized application platform, which solves the problems of bitcoin's technical limitation in currency application and insufficient function expansion, so it has great technical advantages
3. Bitcash (BCH)
BCH inherits a small part of bitcoin's legacy, the name of bitcoin's cash is also good, and the image logo also inherits a part of bitcoin. The ecology of BCH is also good
BCH pursues to be a world currency and an underlying platform for chain application. BCH is actively deploying the main chain expansion and developing the two-tier network to realize the ideal
the whole ecology should be made efforts from two aspects. The first direction is the expansion of the main chain, payment experience and function improvement. Capacity expansion is the guarantee to keep the certainty of monetary transaction fees very low. Improving the payment experience, including popularizing zero confirmation, pre consensus, and possibly shortening block time, are all evolving towards a better payment experience. The main chain function is perfect, including Op_ Return expansion, token issuance, new opcode addition
with the expansion of BCH main chain function, BCH based applications can be developed. The most famous are the decentralized microblog like memo, the paid download seed application like joystream, and the decentralized encrypted communication like Keyport
the second direction is to develop layer-2 network. Build a new blockchain based on BCH network, such as wormhole and kenoken, which are similar to Ethereum network based on BCH. BCH undertakes more complex block chain functions, such as notification contract, through two-layer network. The competition direction of BCH layer 2 network is to compete with the side chain of BTC
4. Lightning bitcoin (LBTC)
bitcoin has been developing for 10 years. In this decade, bitcoin has experienced three important splits, and now it has become four kinds of currencies. The first is BTC, which has inherited most of bitcoin's heritage; The second is BCH; The third is BSV and the fourth is LBTC
LBTC was born to break the power monopoly of big miner and bitcoin core bitcoin, introce more new features and functions for bitcoin, and greatly improve its performance. Lightning bitcoin (LBTC) is a peer-to-peer e-cash system, which is an innovative experiment based on bitcoin. It uses the dpos consensus mechanism based on utxo to separate the voting right and accounting right, so that the token will not be kidnapped by any party. It is a global value Internet transmission protocol with high speed, low handling charge and high scalability. Due to the adoption of dpos consensus mechanism, users can participate without professional mining machines, achieving real decentralization
the above four are the most mainstream bifurcated versions of bitcoin protocol. They are also investment procts that can realize your desire of soaring wealth. Senior managers can play with them, but the premise is that you need to be prepared for huge losses - because they are very volatile
for Xiao, I would like to say: Although virtual currency is a secret weapon for ordinary people to counter attack the sudden wealth, it's very difficult for you to make a lot of money from it
in addition, at present, the price of virtual bitcoin is at a high level, and it can not be ruled out that it will mainly be sideways in 2019. At this time, I think it is a good choice to some other mainstream bifurcation currencies, such as BCH, BSV and LBTC.
