What are the two parts of bitcoin

2.

The capacity of a block in bitcoin is 1m (megabytes). A transaction is between 250 and 500 bytes

according to this algorithm, a block contains about 4194.3 transactions

the confirmation time of a block in bitcoin is 10 minutes, so the seven transactions that a block can process per second may sometimes be less than seven

What are the consequences

The bifurcations of

bitcoin are divided into hard bifurcations and soft bifurcations

hard fork means that when the block format or transaction format of bitcoin changes, the UN upgraded nodes refuse to verify the blocks proced by the upgraded nodes

the upgraded nodes can verify the blocks proced by the non upgraded nodes, and they continue the chain they think is correct, so they are divided into two chains

What is soft bifurcation

soft bifurcation means that when the data structure of bitcoin transaction changes,

UN upgraded nodes can verify the blocks proced by upgraded nodes,

and upgraded nodes can also verify the blocks proced by UN upgraded nodes

3. No! Your hardware is too poor... Even most of your home computer hardware is too low-end. Bitcoin mining needs CPU, especially graphics card, to continuously perform super big data operations for a long time. Usually, it uses high-end CPU and multiple top graphics cards to run in parallel, The electricity bill alone is not affordable to many people... Unless it is convenient to work... Use the public computer... Otherwise, you will die

5. After level 70, about 1 ignore = 4 panel attack, when the equipment is normal.

6. Bitcoin is a virtual cryptocurrency based on decentralization, peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology

7. I don't quite understand what you mean. Bitcoin is not divided into segments. Bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system

I think what you're talking about is that bitcoin is often hung up on the Internet, which I know is divided into different levels. The higher the level, the higher the income and investment. But I feel like it's a hoax. This thing has nothing to do with bitcoin. Their promotion model is suspected of MLM. They told me they were mining, using thousands of computers across the country. If you are in the mixed currency circle, you will understand that ordinary computers can't find bitcoin now, let alone thousands, even tens of thousands of ordinary computers can't find a bitcoin a year. In addition to wasting electricity, there is no profit at all. How can I give you money without profit. Now there are thousands of professional mining machines, which can dig a coin a day. Now the cost of mining is basically higher than the cost. Of course, the electricity charge is free. Now the world's well-known mines have stopped mining because of the sharp drop in currency price

this scam is not very clever, but I don't know why so many people believe it. Of course, some people tell me that I can make a lot of money every day. I want to say that if there is no sweetness, will you do it, will you pull the head, and will you invest more? Some time ago, bitcoin house reported a MLM coin. An aunt was dazzled by huge profits and was cheated by more than 20000 people.

8. Bitcoin bifurcation, this topic may make many people curious, so this article is written for ordinary readers. It doesn't involve the knowledge that has been debated before

the original version of bitcoin was carefully arranged by Nakamoto, and has always been very clear. The debate is about growth. In 2008, he answered the first question about the design of bitcoin, saying:

visa processed 37 billion transactions in fiscal year 2008, or an average of 100 million transactions per day. So many deals require 100GB of bandwidth = 12 DVDs or 2 HD quality movies = about $18 of bandwidth at the current price

assuming that the bitcoin network reaches this size, it will take several years. By then, sending two HD movies over the Internet may not be a big deal

at that time, he was more tired of bitcoin expansion than any of us. His plan is to make bitcoin popular from the beginning, and he knows that this success will change how people use his system. In 2010, he said, "it's good that we keep [blockchain] files as small as possible

the final solution will not care how big it (blockchain file) becomes

but now, keep it small while it's still small, and the growth of new users will be faster. When I finally implement client only mode, it's no longer a problem
"
in 2011, through a series of calculations, I expanded the expansion intuition of Nakamoto in detail: if bitcoin becomes so popular, will it completely replace visa? The answer is that his plan is credible - you don't need anything else but a computer, even if there's so much traffic. Before he left, I also implemented the model he talked about

it was Nakamoto's plan that brought us together. It has changed the lives of thousands of people around the world. Some of us give up our jobs, others devote their spare time to the project, others set up companies and even travel around the world. This is an idea that ordinary people can complete mutual payment through blockchain and create this global community

that's the vision I signed, and that's the vision Gavin Andresen signed, and that's the vision signed by millions of developers, founders of startups, evangelists, and users around the world

and this vision is now in danger. In recent months, it's clear that a small group of people have completely different plans for bitcoin. These people have never really understood Nakamoto's intention because they are worried about success, if the technology has never been improved, if people can't run bitcoin on their home computers? Doesn't this make bitcoin move away from centralization and more like banking? What if people start to rely on bitcoin, even if it's imperfect

now, Nakamoto has chosen to disappear, and they want to make a major change: substantially increase transaction costs, end support for mobile P2P wallets, give up unproven transactions, and many things that have never been found in the project's founding documents

the so-called lightning network, which is about to be promoted as a substitute for Nakamoto's design, does not exist. The white paper describes that it was announced earlier this year, and if it can be realized, it will be a huge departure from the bitcoin we know and love. Pick one of the many differences, and a bitcoin address won't work. What they will be replaced with has not yet been worked out (because no one knows). There are many other surprising pitfalls that I mentioned in another article. What will it eventually proce to make our existing bitcoin network better? It is still extremely unclear.

9. A kind of e-currency proced by open source P2P software is a kind of network virtual currency. As a global consensus initiative cryptocurrency, it is also a peer-to-peer payment system and virtual pricing tool. It is called digital currency by some people. It was first launched in 2009 as open source software by the unnamed developer Nakamoto. Because it uses cryptography to control the proction and transfer of money, bitcoin is also considered as a cryptocurrency. Bitcoin does not rely on specific currency institutions to issue, it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions.
