Bitcoin lightning network does not need to set up nodes
According to 1ml data, the current number of bitcoin lightning network nodes has reached 18061, an increase of 7.30% in the past 30 days; The number of channels was 40065, which increased by 5.9% in the past 30 days; Network capacity reached 1154 BTCs, an increase of 6% in the past 30 days

Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system
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~
Lightning network is known as one of the most effective cryptocurrency expansion solutions currently being developed. The scheme was proposed in 2015, based on a network at the top of bitcoin blockchain, and finally implemented on the network. The network consists of user generated channels that send payments back and forth in a secure and untrusted manner
For example, suppose I want to pay for every minute I watch. We're going to open up a lightning channel, and as time goes on, we're going to make regular payments from my wallet to the video makers. When I finish, we will close the channel to settle the net balance on the bitcoin blockchain. Because transactions are only between me and the other party and do not need to be broadcast to the whole network, they are almost instantaneous. And because there is no incentive for miners, the transaction cost is low, or even no transaction cost at all
It has been ten years since bitcoin was born. Ten years ago, if someone had told his founder, Tsui Nakamoto, that this new decentralized currency would flourish in 2019, he might have thought his experiment was a success. Bitcoin is indeed likely to become a world currency. Even if it is not as magical as Nakamoto said, even today, 10 years later, there are still people criticizing the ideas in its white paper
Although bitcoin has become a widely used investment and speculative asset, e to its own design and huge demand, bitcoin is far away from its goal of completely decentralized free currency. But if the new solution does solve some of the existing problems, then its status quo will certainly be greatly improved< as long as the transaction cost of bitcoin blockchain is not higher than lightning network, users will not transfer assets to other public chains. If bitcoin blockchain can continue to expand the transaction processing capacity through other solutions besides lightning network in the future, it may eventually develop into the world currency originally conceived by NakamotoIn February 2015, bitcoin developers Joseph PON and Thaddeus dryja proposed the concept of scalable off chain payment -- Lightning network in their paper the bitcoin lightning network: scalable off chain instant payments. We know that a very important reason why the bitcoin network is reliable is that all the bitcoin nodes keep the bitcoin account books. If someone wants to tamper with the transaction records, they need more than half of the computing power of the whole network. Without the trust machine of blockchain network, how can we ensure that both sides of the transaction will not go back and deny? How is lightning network realized
in short, the lightning network is based on the expansion of bitcoin. Due to the limitation of bitcoin block, a new channel is required. The process of small amount delivery can be realized through the channel of lightning network without bitcoin miner accounting, which can speed up the speed and rece the handling charge. But how can such lightning network prevent the centralization problem? More details this video is very detailed: six minutes to understand the lightning network
but how long can the lightning network land
1) new transactions broadcast to the whole network
2) each node brings the received transaction information into a block
3) each node tries to find a workload proof with enough difficulty in its own block
4) when a node finds a workload proof, it broadcasts to the whole network
5) if and only if all the transactions contained in the block are valid and have not existed before, other nodes agree with the validity of the block
6) other nodes indicate that they accept the block, and the method of indicating acceptance is to follow the end of the block, create a new block to extend the chain, and regard the random hash value of the accepted block as the random hash value that is faster than the new block
hope to help you.
