How to dig bitcoin in 2009
Find the code on the bitcoin system, and you can dig bitcoin if you find the code
every other time point, the bitcoin system will generate a random code on the system node, and all computers in the Internet can search for the code. Whoever finds the code will proce a block, and then get a bitcoin. This process is often called mining. Computing this random code requires a lot of GPU operations, so the miners purchase a large number of graphics cards to get bitcoin profits more quickly, which is also an important reason for the recent shortage of graphics cards
extended information:
characteristics of bitcoin
The total amount is limited, only 21 million BTC2. Anyone can issue bitcoin, but it is more and more difficult
3. Compared with the central bank currency, it is safer and almost impossible to be stolen
The transaction process is completely anonymous and cannot be tracedin 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 post 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.
Step 1: prepare mining machines and pools
if you want to dig bitcoin, you must prepare professional equipment. At present, there are many professional mining machines on the market, and the pool is also essential. When you choose a pool, you should also compare the output and income gap of each pool, and then choose the most suitable one
Step 2: register and set the mine account
after the mine is ready, register the mine account and set a common email. When setting the mine account, each CPU or GPU needs to set a mine account
Step 3: download the bitcoin miner
after you register and set up your account, you need to download the bitcoin miner. When downloading the miner, be sure to choose the miner that can make your CPU and graphics card play the most function. After downloading, set the server, user name, password, device and so on
Step 4: Mining
after setting up the miner, click the "start mining" button, the miner will enter the state of full speed operation, and the miner will start mining automatically.
When bitcoin nodes connect with each other, they will get transactions they don't have from each other. But because bitcoin has accumulated a large number of transactions for a long time, it is very difficult for two nodes to compare which transactions you are missing / which transactions I am missing one by one
to solve this problem, Nakamoto Tsung invented the important technology of block chain. Nodes use blocks to synchronize transactions, which ensures the data consistency of all nodes, and ensures the uniqueness of the blockchain by competing for block packing rights (that is, mining)
① a block and blockchain
a packet formed by a transaction over a period of time is called a block. On average, bitcoin generates a block every 10 minutes, and each block is linked to the previous block to form a blockchain
② the transaction data is synchronized with the block as a unit
the block is numbered from 1, so after node a connects with node B, it is convenient to synchronize the transaction data as long as the block number height of both parties is checked. For example, if node A's own block height is 100 and node B's block height is 110, all it needs to do is request B to synchronize the 10 blocks 101-110<
③ reward for packed blocks
in order to ensure that there are nodes to pack bitcoin transactions, bitcoin rules stipulate that nodes of packed transactions will receive bitcoin as reward
A. part of the package reward comes from the transaction fee paid by the transaction creator (100-1000 transaction fee per KB)
B. the other part comes from the initial distribution of 21 million bitcoins. At the beginning, the reward is 50 bitcoins for each block. After that, the reward will be halved for every 210000 blocks (about four years). Until about 2140, the reward for each block is less than 1, and the total reward for each block is 21 million bitcoins, This is the source of the total amount of 21 million bitcoins (2099999.97690000 to be exact)
after 2140, the package reward will only come from the transaction fee paid by the transaction creator<
④ competition for block packing right
node packing transaction only needs to consume very low-cost network and computing resources. The existence of packing reward (at present, the packing reward for each block is 25 bitcoin, about 40000 yuan), makes a large number of nodes want to pack transactions. In order to ensure the uniqueness of the blockchain, bitcoin rules stipulate that nodes use a method similar to "coin tossing" to compete for the right of transaction packaging. Nodes constantly toss coins. Whoever first throws the results that meet the rules will get the right to pack the transaction in this block, as well as the package reward of this block
1 dollar = 1300 bitcoins. This is bitcoin. In 2009, 1 dollar = 1 bitcoin in 2011, 900 dollars = 1 bitcoin in 2013, and about 3880 dollars = 1 bitcoin on August 20, 2017. The highest price of bitcoin in history was on December 17, 2017, 19756 dollars per bitcoin
bitcoin is a virtual currency, and the total amount is set at 21 million, and the total amount is fixed. Bitcoin players can buy special video card miner to excavate bitcoin, and halve the number of mining bitcoin every four years until 21 million pieces have been excavated
so far, bitcoin has been halved twice, more than 17 million pieces have been excavated, and only about 4 million pieces remain to be excavated. According to some estimates, the last bitcoin will be excavated in 2140
General currency is decided by the central bank and virtual currency is decided by indivials. The sovereignty of general currency is in the center of the Republic; The sovereignty of virtual currency lies in distributed indivial nodesfrom the perspective of information economics, general currency is a special case of virtual currency. The special point of this special case is:
first, the reference point remains unchanged. Therefore, value is specialized from a set to a recible value. When the reference point remains unchanged, value is equivalent to utility
Secondly, the gain and loss of utility relative to the reference point remain unchanged. This means that the value of reference point is a stable rational value and equilibrium value. In a rational economy, the reference point may remain unchanged, but it is still a scattered set. The difference is that every point (the actual transaction price) of this decentralization is unstable, and only the equilibrium value is stable But in the value concentration of virtual currency, every point may be stable, on the contrary, the rational equilibrium value may be unstable. Reflecting on the monetary decision mechanism, the central bank is the personified representative of a fixed reference point of rational value, while the virtual money market (such as stock market and game money market) is determined by forces other than the central bank It is in this sense that some people in economics call the stock market virtual money market and the economy formed by stock market and derivative financial market virtual economy. The essence of virtual economy is information economy with indivial as the centernow in bitoffer, you can buy a bitcoin equity, that is, an option, for as little as $5.
