Block chain Knowledge One

In real-life cash transactions, there are two types of roles: people and banks; passerby a bank card registered in the bank, the application of the bank card will let a enter the trading password, and each bank card has a unique card number; so that a person can pass this card to the bank card to deposit a certain amount of RMB, When he needs to transfer money to other people, only need to know that person's bank card number, through the bank's electronic trading system can complete the remittance;

In such a scenario, the bank generally by the credibility of the organization of single person, so that users can rest assured that the money deposited in the bank; The bank here we can understand as a ledger that everyone can account for in this ledger, such as deposits, withdrawals At the same time, everyone can view the financial situation and transaction records in their accounts in real time; But the bank's huge ledger is not shared, that is, it cannot view other people's account information; So we can say that the bank is a central organization with considerable credibility;

If the bank's trading system is affected by hackers or their own system, causing problems in the system, then the bank of the huge ledger will be affected, loss of funds, transactions, and so on, a new type of accounting system, so the block chain was born.

Block chain is also a ledger, the professional term is a distributed shared ledger system, which has the same function as a bank, and can be used for bookkeeping, storage, consumption, etc. he and the bank also have a different place, that is, this block chain book each person can see the contents, and each person also has a ledger, Just like in real life everyone has a bank card, but each person's own account of the operation will be synchronized to other people; block chain has the following characteristics:
1: He is an infinitely long chain, in each chain contains a block, we can interpret the block as a page of the ledger
2: This chain is orderly, and each block contains specific information and the information is encrypted and processed
3: Block chain is a kind of central, or weak central, or full of the center of a ledger system; to be centered we can understand that any node/block can be secured to a point-to-point transaction without a third party trust Frost. His security is guaranteed by the asymmetric encryption technique of the block chain.
4: Block chain is an open source technology, using this technology we can create a lot of applications, such as Bitcoin;
5: Block chain of each block composed of an orderly chain, the longest chain is considered from the CPU is the largest pool of computing power (mining pool)

The inventor of the block chain "Zhong Ben Cong" is a very God-obsessed person, so far no one knows its true identity, nor how many coins he owns; the first block created by Ben Cong, we are often called the "Genesis Block"

Tell me a more interesting story, let's figure it out.

This picture is the first time since the emergence of Bitcoin, a bit of the value of the electronic currency to carry out the event, a programmer named Laszlo Hanyecz, agreed to pay an Englishman 10000 Bitcoin, let him help himself from the local bar John order a pizza. As evidence, Laszlo uploaded photos to the Bitcoin forum, where the real world's first bitcoin trading was born.
