1. Give you an easy to understand example, you can quickly understand what blockchain is:
in a village, a spent 3000 yuan to buy a cow of B, how to record this account
so a and B found a mutual trusted C to record the account, but later a and C colluded and did not admit that a had bought B's cattle, so the deal became rough and disputes continued
later, B had another cow. Of course, B didn't sell it to a this time, because a had no credit, so he gave it to d. This time, instead of looking for witnesses, they went to the whole village to roar after the transaction. B said Wang Erhua paid 3000 yuan to buy a cow from me, d also went to the whole village to shout that I paid 3000 yuan to buy a cow from B, so there were many people in the village to record the transaction. In this way, there will be no bad debts, which is called decentralized and distributed accounting
here comes the problem
when you yell, are the villagers willing to charge for you, just because you have a big face
therefore, the first person to record accurately will get some bitcoin rewards
someone asked, what if two people finish the first record at the same time
in order to avoid this problem, it is necessary to set rules, for example, to answer a question first, or to record with feet, and it must be written in block letters. If you set a series of rules, there will not be many firsts
in the network, there are a lot of transactions going on every day, and there are also many people recording, and finally they get the reward of bitcoin. This process is the legendary mining
Mining requires a lot of equipment. We call these computer equipment mining machines
in this way, all the processes are in one system. The system will encapsulate the data every 10 minutes to form a box full of data, which we call blocks
with the continuous generation of blocks, they are linked together to form a blockchain.

2. Compared with BCH and BSV, lightning bitcoin LBTC is also derived from bitcoin, and its original intention is to solve some shortcomings and defects of bitcoin itself. However, the biggest difference of LBTC is that it adopts dpos consensus mechanism instead of pow consensus mechanism. The most significant advantages of LBTC are as follows:
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.

Plustoken wallet is not reliable
on June 29, 2019, plustoken, the largest blockchain investment project, was reported by users that it was unable to withdraw money, and then six founding team members were arrested in Vanuatu for suspected Internet fraud. In the previous article "tracking the asset transfer of plustoken with pictures and texts", the preliminary tracking statistics showed that there were 1203 BTC inflows into the exchange
At the same time, peckshield found that another transfer address at the beginning of 1m1tfsvb in the monitoring transferred 5575 BTCs through multiple decentralized and small amount transfer out, and it is not sure whether it will flow into the exchange. However, ETH, EOS, XRP and other currency assets have no abnormal trend4. Hello
