Virtual currency -- Lightning bitcoin
First of all, all parties need to establish a multi signature wallet (more than one signature is needed for transaction). This wallet has some bitcoin in it. Then the wallet address is saved in the bitcoin blockchain. In this way, payment channels are established. Both parties can now conct an unlimited number of transactions without touching the information stored on the blockchain. For each transaction, both parties sign an updated balance sheet to always reflect the ownership of bitcoin stored in the wallet and the number of each transaction
after both parties complete the transaction and close the channel, the balance generated will be recorded on the blockchain. In the event of a debt dispute, both parties can use the recently signed balance sheet to recover their share of the wallet. There is no need to establish a direct channel for flash trading, users can send payment to someone through the channel of the person they have contact with. The network will automatically find the fastest trading channel
with the adoption of segwit in bitcoin and lightcoin networks, the development of this technology has been greatly promoted. Because if there is no upgraded transaction scalability patch, the transaction risk on the lightning network will be too large to implement. Without the blockchain security behind it, lightning network will not be so secure, which means that it will be widely used in small or even micro transactions with less risk

then why should I say that lightning bitcoin is a great currency experiment? We compare lightning bitcoin to a free economy with three major stakeholders: developers, miners and holders
so far, no blockchain project can effectively govern the three. Why? The reason is very simple. In an ICO project, the developers, coin holders and even miners are the same group. It's easy to understand. Why should he give the best interests to the ICO holders? This is obviously not in line with human nature. The reason why lightning bitcoin dares to do chain governance is related to the issuing mode of lightning bitcoin. LBTC's "governance on the chain" is another attempt to "decentralize", which is also very eye-catching. Dpos mechanism determines that there are 101 nodes in the network. At the same time, unlike pow, the right of choice is in the hands of the coin holder. These nodes will be elected by the vote of the coin holder. When the node does not act, the user can vote out of the network. According to last week's weekly report, LBTC's block browser has also added this function, which can view the operation of nodes in real time. It also paves the way for LBTC's "chain governance". In the LBTC system, all coin holders can vote to decide whether the project development proposal will go or stay, and all members of the organization can participate in the decision-making and operation of the organization. In addition, the 5000 standard of lockup after the election of the lightning node ensures that the node is both a mine pool and a coin holder. In this way, the relationship among miners, developers and users is well balanced, and the foundation of an autonomous organization is formed.
To be honest, I had the same problem with the subject at the beginning. When I saw the news, I was a little confused and went to search. As a result, when I searched for lightning bitcoin or lightning bitcoin, either lightning network or bitcoin came out... This name is quite poisonous
Let's get down to business. Let's draw a conclusion first. It's not a thing at allmany people have talked about what lightning network is. You can look at other people's answers to get a deeper understanding of its mechanism, or you can go to the official website with better English to see their papers directly http://lightning.network/ . Lightning bitcoin official website in Chinese, save the trouble of translation https://lbtc.io/ . The origins of the two lightning bolts are very similar. They both hope to solve the problem of bitcoin network congestion. One is to carry the protocol, and the other is to change the fork to consensus. The results of the two lightning bolts are also good. The transaction speed is greatly improved, which can be regarded as real-time. The following table directly shows the similarities and differences between the two:
as can be seen from the above, the differences between the two are relatively large, and should not be confused any more~
first, it greatly improves performance, As we all know, the number of transfers per second of bitcoin, that is, TPS, is only about 7, and other bitcoin forked coins using POW consensus mechanism are almost the same. The theoretical value of TPS of LBTC can reach 2800, and the current actual level can reach more than 1000, and the performance has been improved by several orders of magnitude. The slogan "fast as lightning" is by no means empty words. If you are interested, you can download a wallet from the official website of LBTC or Cobo to experience it
Second, it greatly reces the energy consumption and participation threshold. As we all know, the high energy consumption caused by POW mining represented by bitcoin has been criticized by the outside world. At the same time, because mining has already become a heavy asset instry, mining machinery, mining and other fields have been monopolized by a few big players, ordinary small and medium-sized investors and new manufacturers have little room to survive, It has formed a situation in which the strong are always strong. However, POS / dpos currencies only need ordinary PCs or even mobile phones to run wallets and stack, so as to obtain revenue
thirdly, it introces chain governance, which achieves a good balance between democracy and efficiency. At the same time, it encourages users to actively participate in community affairs through voting and staging mechanism. In the world of pow, power is power, simple and crude; In the world of POS, those who hold more money will have more right to speak and gain
in the world of dpos, it is not simply to see who holds more money. At the same time, it needs the extensive support of the community to exercise power on behalf of the community. At the same time, the majority of small and medium-sized users also have the opportunity to launch motions, express their demands, and participate in decision-making
because bitcoin has carried too many interests, we are very cautious about any improvement of bitcoin, and the pace is very slow, which leads to the division of the community and the proction of many forked coins. However, in fact, compared with bitcoin, the improvements made by BCH and BSV are quite limited, so the improvement in all aspects is also very limited
therefore, if you take a closer look at LBTC, you will find that it is actually a very interesting bitcoin fork coin. I think it is a very bold and imaginative experiment based on bitcoin. If lightcoin has been used as a testing ground for new technologies and new ideas for bitcoin in many cases, LBTC can be regarded as a testing ground for bitcoin with greater and more thorough changes
just mentioned, one of the biggest obstacles in the promotion and use of bitcoin is that TPS is too low to carry high-frequency transactions. Compared with bitcoin and some well-known bifurcated currencies such as BCH and BSV, the performance of LBTC is improved by several orders of magnitude, and the actual TPS can reach more than 1000
increasing TPS can rece verification time, but it will inevitably sacrifice security or decentralization. If TPS increases blindly, blockchain will completely sacrifice "decentralization". At the same time, the requirements on the miner's machine configuration will be more stringent. If it can not upload the transaction in time, it will proce more unfinished transactions, and the hidden danger will be greater. Although EOS uses 21 super nodes to achieve high efficiency, it also sacrifices some "decentralization" and security, and introces potential risks such as DDoS
in the past two years, many public chain projects blindly pursue high TPS, and often claim to have achieved tens of thousands, hundreds of thousands or even millions of TPS. In order to improve TPS, some project parties buy millions of equipment to test in a laboratory, which only plays a PR effect or amuses themselves. Such a high TPS is meaningless. Even if it can reach or close to such a number, for the current market demand, it also belongs to excess performance, which is bound to cause unnecessary waste of resources
according to the calculation of relevant research institutions, even if the public chain processes 100 million transactions every day, thousand level TPS is enough. It's worth noting that the TPS of Libra, which is to be launched by Facebook, is also around 1000. You should know that Facebook has as many as 2.7 billion users in the world, which should be determined by them after careful consideration
this means that LBTC's TPS can meet the needs of processing 100 million transactions per day, which is quite pragmatic and can fully meet the needs of global users in the next few years. Moreover, LBTC also has a high degree of scalability. With the further improvement of global Internet infrastructure, the performance of LBTC will continue to improve. It can be said that the current LBTC has found a good balance in the "Impossible Triangle" of efficiency, security and decentralization
in the view of many bitcoin fundamentalists, only the pow path chosen by Nakamoto is the only right way. POW consensus mechanism has experienced nearly 10 years of stable operation and continuous market test, and dpos has been more than 6 years since its birth. So how about doing an experiment to see what wonderful chemical reactions can be proced by combining bitcoin with dpos
if this dpos version of bitcoin can also withstand the continuous test of 10 years, will we still insist that only POW is the only right way for bitcoin? Of course, we don't have a definite answer to this question. Time will tell
although I also claim to be a believer of bitcoin, I think the existence of LBTC is very meaningful. This significance does not mean to replace bitcoin, or like some fans of other forked coins, I think that only the branch I support is the real bitcoin, but to explore more and wider possibilities in technology and form a useful supplement to bitcoin.
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.

today's price is about $10000 per bit, equivalent to RMB 65539.06 per bit. It can be said that it is an unprecedented high price. If you have it now, it is not recommended that you wait for it. After all, it is not good to lose money. Many big platforms can exchange it.
the working principle of lightning network is to create an interweaved network composed of two payment channels. Basically, it's a trade between two people. However, by creating a network in which all channels are interconnected, you can route payments through multiple channels. If you want to send payment to anyone in the network, you can credit the account directly connected with yourself (deposit money to the account) in your Lightning network channel, and then the account can credit the account connected with yourself (the amount is the same, so there is no actual change in value). This process continues, Until you pass it on to the participant you actually want to trade, he will receive the money
therefore, technically, you are only trading with an account directly associated with the payment channel where your funds were originally sent. So, every routing connection between you and the ultimate payee is made up of two participants who simply trade with each other, each of whom accounts for each other - a series of double entry paths. Lightning network is a network composed of double entry accounting channels of two participants, so there is no bottleneck in transaction throughput.
