1. What is blockchain? Blockchain is a technical solution to collectively maintain a reliable database through centralization and distrust in the past. The concept of blockchain first appeared in a paper "bitcoin: a peer-to-peer e-cash system" written by the founder of bitcoin, Nakamoto, in 2008. In short, blockchain is a kind of public accounting technology, which was born to solve the trust cost in our transactions
what is blockchain? Blockchain technology is a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. So it's very important who keeps this account book. At present, whose system will keep accounts, wechat's account book is Tencent's account book, and Taobao's account book is Ali's account book. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there is any data change in a certain period of time, everyone in the system can conct bookkeeping. The system will judge the person who has the fastest and best bookkeeping in this period, write the content of his records into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. This way, we call it blockchain technology
what is blockchain? For example, in our daily online shopping, the money paid after placing an order for the selected goods will first be paid to the third-party payment platform, and the third-party payment platform will only pay the money to the seller's account after the seller delivers the goods to the buyer to confirm the receipt
when a transaction occurs between the buyer and the seller, the system will broadcast the transaction information between them. The person who receives the message will record the transaction after confirming that the message is correct, that is, the person who receives the message has made a data backup for the transaction
just like Zhang Ergou bought an inflatable doll on the Internet, the system would hold a loudspeaker and shout in the village: "Zhang Ergou bought an inflatable doll"“ After hearing the broadcast, the villagers took out a small notebook and wrote it down. Zhang Ergou bought an inflatable doll. Here, the recorded information is like a data backup for this transaction. Back to the current online shopping, if Zhang Ergou's order problems, Alipay system failure can not record this transaction, then Li Goudan's money is not white. On the blockchain, if there is a problem with the order, because in the early stage, the system broadcast everywhere that Zhang Ergou bought an inflatable doll with a loudspeaker, so countless people recorded the transaction information, and there would be no system failure to record the transaction records
what is blockchain? At present, blockchain technology is very popular, especially in the financial sector. Ant finance, LETV finance, Wanda, Ping'an and Minsheng have successively tested blockchain projects, and eurocrowdfunding is in the forefront of using blockchain technology
blockchain is a large-scale and decentralized economic organization mode realized by a group of technologies
bitcoin is a practical embodiment of blockchain technology, which is more accurate than the former
in fact, whether it's blockchain or bitcoin, people are more concerned about the coin itself, which coin makes more money and how to join it
what is blockchain? Blockchain has attracted wide attention because it has changed the original economic organization mode in many fields. For example, in the process of currency issuance and circulation, cryptocurrency makes the core role of the banking system decline, and the organization mode among the central bank, commercial banks and users has changed significantly; In Ethereum erc20 token system, blockchain has completely changed the organization mode among securities issuers, participants at all levels and regulators. Although it brings some problems, it also improves the efficiency of securities issuance and circulation
people are now exploring the application of blockchain in various fields of economy. In essence, they are looking for new ways to use blockchain to adjust or innovate the original economic organization mode of enterprises, instries and regions, and to rece costs and improve revenue. As an economic organization mode, blockchain can be extended downward to its implementation technology, and upward to its impact on social organization and social consciousness, which makes it easier to understand the complex social impact brought by blockchain.

2. Today's e-commerce platform applications rely on centralized servers. If the server cluster goes down, the whole platform will stop working. The decentralized blockchain + e-commerce platform, business services and storage space can be provided by community members, which enables network services to continue to operate as long as some network nodes are still running. We need to know more about the instry dynamics of the blockchain + e-commerce platform. We can pay attention to the next dimension and share a lot of dry goods.
3. I'm very responsible to tell you that blockchain is definitely not a scam. First of all, the most talked about blockchain is digital currency. Here I want to state that there is no digital currency out at present. As you know, bitcoin, Ethereum, reborn, etc. are all digital encryption codes, and they don't have full purchasing power. At present, they are only in the stage of speculation. Blockchain is widely used in the future It will certainly overturn the existing economic model and affect the way of human life. Compared with the Internet, it will have a qualitative leap. Loser poor want to become a billionaire. This is the best shortcut. If you want to know more, you can continue to ask questions

"tomorrow will be tomorrow, and there will be so many tomorrow; My life is waiting for tomorrow, and everything will be done in vain. "Just a few lines of poetry are the crystallization of the life experience of our ancestors after thousands of songs and hardships!
