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. Blockchain is a technology, and the underlying technology of bitcoin is blockchain. Blockchain features: decentralization, anonymity, security, transparency, traceability, irreversibility, etc
according to the development of blockchain, it can be divided into three stages:
blockchain 1.0 stage: when the digital currency represented by bitcoin first appeared, it was probably from 2008 to 2014
blockchain 2.0 stage: from the birth of Ethereum to the eve of "94 event" in 2017, this is the development era of smart contract and blockchain
blockchain stage 3.0: after the "94 event", we began to pay attention to the exploration and development of blockchain applications and reshape the technology and value of blockchain
although blockchain technology has been widely recognized, people still cannot do without digital currency. After all, the underlying technology of digital currency is blockchain. Even though the non currency blockchain on the alliance chain can be advocated by mainstream regulators, it is much more difficult than the real decentralized blockchain such as public chain projects. What technology geeks pursue are often more difficult decentralized projects
therefore, digital currency will not be destroyed, which is the development trend. As for how you say to play, maybe you are asking how to play digital currency instead of blockchain? If you really want to deepen the understanding, you may as well go to Citex (big C network) to have a look, hope to adopt, thank you.

3. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block.
