Which two coins are bitcoin divided into now

1.

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

2.

The concept of 21 million

bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

bitcoin is not issued in unlimited quantity, which is different from most currencies. Bitcoin does not rely on a specific currency issuer. But according to the specific algorithm, through a large number of calculations. Its circulation is controlled by software algorithms. The total number is 21 million

generation principle

starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique[ 10] In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client. After installing the bitcoin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost

3. BCC is not a bifurcated currency. BCC is a new type of blockchain asset based on the original bitcoin chain
BCC does not meet the definition of bitcoin network bifurcation. BTC and BCC are two completely different chains in two days. As like as two peas, the whole network as like as two peas, which can not be synchronized in one chain, has two pieces of block chain network with identical bitcoins. Two networks have a large number of miners digging, and transactions on two different networks can not be synchronized. This leads to two even the same difficulty of two parallel chains, which is called forking.
BCC has also been identified by bitcoin international Roundtable forum as a competitive currency that replicates bitcoin blockchain and modifies some codes. Therefore, it is a wrong interpretation that BCC is the network fork of bitcoin.

4. As of August 8, 2017, 16495200btc has been mined, and the total number of undeveloped is 4504800btc.

5. 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

6. The total number of bitcoin is 21 million. It was g up in 2140, and the mining speed has been halved in four years. At present, more than 13 million bitcoins have been mined. Bitcoin was invented by a man named Nakamoto, who disappeared in the bitcoin circle after 2010. No one knows who this person is

bitcoin is used for graphics card mining. It used to be OK, but now there is almost no profit from using graphics card mining. Of course, if your electricity is free, it's OK. The graphics card mining you mentioned is the second stage of bitcoin mining. The first stage is mining with CPU, which is an ordinary computer. The second stage is the graphics card mining you mentioned, commonly known as burning graphics card. At present, it has entered the third stage of ASIC mining machine mining stage. In this stage, the computing power is very high, the mining income is very low, and the mining cost is almost close to or even more than the currency price. At present, the profit of large-scale mining mainly depends on the energy consumption of mining machine and the advantage of electricity price.

7. Who told you that bitcoin will soon be divided up? Besides, blockchain bitcoin is not a single value function. If you participate in it, you can also save distributed account books. This is not measured by value, and it will make the blockchain era in the future. If you have the strength, I suggest you participate in the proct of the era. Ha ha

8. The game between the two forces of the currency circle is controversial on whether to expand the capacity
two key figures in the bitcoin field have developed another version of bitcoin. They are Gavin Andresen and Mike Hearn, the chief developers of bitcoin
for several months, Anderson and Hearn have been arguing with the other three chief developers of bitcoin: whether the blocks processed in bitcoin transactions should be further expanded from the current 1MB, so as to be able to process more than three payments per second
this new version of bitcoin, called bitcoin XT, increases the capacity of the block to 8MB and can complete 24 transactions per second. Although it is far lower than visa's processing speed of 20000 transactions per second, it will increase every year in the future, so bitcoin will continue to grow
opponents of bitcoin XT believe that increasing the block capacity may undermine the original intention of this decentralized payment system, because the extra computer memory requirements may crowd out thousands of independent "nodes" from the network< Some people think that this split marks the end of bitcoin. But he told Reuters on Tuesday that the cryptocurrency will continue to exist, whether or not it is accepted
"if we thought it might ruin bitcoin's future, we wouldn't do it." He said. He added that since last Saturday, about 10% of the nodes have agreed to use bitcoin XT.
