Bitcoin peer to peer e-cash system

1. BTC is bitcoin and BCC is bitcoin cash, which are two different digital currencies. BCC is a new type of blockchain asset proced by a hard bifurcation of bitcoin. It is a decentralized digital currency supported by a community of large block supporters. BCC removes segwit, cancels the limitation of 1m block size, supports 8m block size at most, and adheres to the expansion route on the chain. The purpose is to better realize the "point-to-point encrypted e-cash system" described in Nakamoto's white paper.

2. The reason why blockchain ledger can be decentralized is that all nodes of the network synchronize the ledger with each other and keep consistent. Therefore, blockchain does not need a centralized bookkeeping institution, so what is the node
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.

3. Bitcoin cash transaction is not congested, and the handling charge is lower

5. Abstract: a person named Satoshi Nakamoto posted a post on the P2P foundation website, saying that he has developed an open-source P2P (peer-to-peer) e-cash system called bitcoin, which is completely decentralized. There is no central server or trustee, and everything is based on participants. Bitcoin Bitcoin is a kind of virtual currency in the form of P2P. Point to point transmission means a decentralized payment system. 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. 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. Bitcoin is a kind of network virtual currency, similar to Tencent's q-coin. You can use bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. As long as someone accepts it, you can also use bitcoin to buy real-life items. 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 has no more than 10.5 million in the first four years, and the total number after that will be permanently limited to 21 million. Another point is that you can use computers to make bitcoin. Bitcoin is an electronic currency proced by open source P2P software. Bitcoin has also been paraphrased as "bitgold". The concept of virtual currency bitcoin was first proposed by Satoshi Nakamoto in 2009. Now bitcoin is also used to refer to bitcoin's open source software designed and released according to the ideas of Satoshi Nakamoto and the P2P network built on it. Unlike most currencies, bitcoin does not rely on a specific central issuing institution, but uses a distributed database throughout the P2P network nodes to record currency transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. For example, bitcoin can only be used by its real owner, and only once, after the payment is completed, the original owner loses the ownership of the bitcoin. Feature bitcoin is designed to allow anonymous ownership and use rights. Bitcoin can be stored in personal computer in the form of computer file (wallet) or in a third-party hosting service. No matter how it is saved, bitcoin can be sent to anyone on the Internet through its address. The distributed characteristics of P2P and the design of no central management mechanism ensure that no organization can manipulate the value of bitcoin or create inflation.
