Bitcoin golden node
1) wallet. It's used to store your bitcoin balance. In principle, as long as you have the private key of your own bitcoin address, you can use your own bitcoin
2) verify the transaction or payment. After receiving the transaction, the bitcoin node will use certain algorithms to verify the validity of a transaction. If you only change the balance of bitcoin in your computer, others will not recognize it. Similarly, your wallet will not recognize the transaction changed by others
3) mining. Core wallet can start mining function through a command to join the mining army, while SPV wallet usually can't (SPV is just passing by). However, it is not the node type that hinders home computer mining, but the rapid development of professional mining machines. Compared with ordinary computers, the computing power of ordinary computers is very small. Mining by ordinary computers is like digging your own backyard with a hoe, and then expecting to dig out gold
because of the demand of bitcoin users, bitcoin exchange was born. The exchange provides a place for centralized trading. People put money on the exchange, and the exchange will match and trade together, similar to stocks and securities. Therefore, banning exchanges does not mean banning bitcoin. Bitcoin network cannot be banned. Bitcoin is sent to the exchange's wallet, and all you see is a balance given to you by the exchange. In fact, you no longer have your own bitcoin. Bitcoin network is global. Where there is a network, there will be bitcoin. After the exchange closes, bitcoin will not disappear, but will return to where it should be.
bitcoin, a blockchain based digital currency, is often regarded as a global safe haven asset like gold. In this age of global turmoil, even gold has become unreliable and may be confiscated as India has. Some people have begun to think that bitcoin can replace gold, because bitcoin not only has the reserve capacity of gold, but also has some capabilities that gold does not have, such as low handling charges, rapid transfer capacity, decentralization and so on. With the increasing popularity of bitcoin and the decreasing volatility, the status of gold has been threatened
will bitcoin shake the status of gold?
gold has a long history, almost as long as the history of human civilization, and has withstood numerous tests in history. Bitcoin is less than a decade old, but its value has risen sharply. There is no support behind bitcoin. Of course, since the end of the gold standard, there has been no support from other currencies, except that there is no support from the central bank behind bitcoin. It's hard to predict whether bitcoin will exist in the next decade, a hundred years or even a thousand years.
the concept of 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. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
from the two concepts, the main differences are as follows: gold is a physical object and a general equivalent; Bitcoin is a virtual currency, which is easy to be manipulated, and its value has a certain degree of hype.
bitcoin is a kind of point-to-point e-cash system, more directly, node to node. Each transaction is broadcast by the originator to the nodes around it, and then broadcast to the nodes around it after receiving it, and finally spread to the whole network
every bitcoin wallet is a node, and the node with a complete blockchain ledger is called the whole node. In October 2017, there were about 9300 nodes in the bitcoin network, which were responsible for broadcasting and verifying bitcoin transfer transactions. After the transfer transaction occurs, all nodes broadcast to the whole network. After the mining node verifies that the transaction is correct, it will be recorded in the blockchain ledger. The United States, Germany and France have the largest number of bitcoin nodes, with China accounting for about 5% of the world's total nodes Data source: bitcodes. 21. CO) running bitcoin node does not provide any reward, and it does not need the whole node to transfer bitcoin, so the total number of bitcoin nodes only accounts for a small part of the node number.
There is no direct link between gold and bitcoin
neither of them is money: money is widely accepted as a medium of exchange, and gold is classified as money. To a large extent, it can be traced back to the early capitalist period, when gold could be used to exchange for anything, as a tradable tool and asset currency, to exchange for a certain amount of US dollars
bitcoin has now become a means of online and offline payment, and many countries have accepted this way, but it has not been accepted by the whole world
