1. In a narrow sense, blockchain is a kind of chained data structure that combines data blocks in chronological order in a way of sequential connection, and it is a distributed account book that can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
nowadays, the mainstream digital currencies are basically developed based on blockchain technology. Blockchain is the underlying technology of digital currency. The domestic tea based digital currency Puyin is developed based on blockchain technology.

2. Decentralized, open and transparent payment and collection technology. If you don't understand, I'll take you to make one. Completely free blockchain digital currency.
3. 1. Blockchain is an account book for recording digital currency transactions
taking bitcoin as an example, it does not have an entity form, but exists in a special account book. All bitcoin transactions are recorded in the ledger. Through the transaction records, we can calculate the number of bitcoins owned by each user. If a person owns bitcoin, it means that he can find the relevant transaction records in the ledger
the ledger mentioned here is a software that we can download from bitcoin's official website, and the underlying technology used in this software is blockchain. In order to facilitate understanding, we usually say that blockchain is the ledger
the reason why blockchain is used as the underlying technology of ledger is to realize the feature of digital currency decentralization. It can be said that the starting point of a series of problems and solutions of digital currency comes from decentralization
2. Blockchain is a technology to ensure the safe use of digital currency. As we all know, blockchain technology has the characteristics of encryption and non tampering, which can rece the probability of errors in the use of digital currency to 0. Because digital currency requires higher encryption, it must be supported by blockchain technology. At present, not only many instries in China are using blockchain technology, but also many foreign countries are actively using blockchain technology.

4. There are many of the best blockchain digital currency trading platforms in China. Please pay attention to the distinction. Foreign ones can also be used.
5. Blockchain + digital currency opens "different" payment methods
with the continuous development and progress of society, great changes have taken place in our lifestyle, such as mobile payment and online shopping, which have brought great convenience to our life. Since the birth of online shopping, online payment has become a part of our life
online shopping is convenient, but it is also through the middle of a "invisible" process of payment, such as we bought something on the Internet, first pick out what you love, then you have to pay the problem:
now most people use Alipay is the way of payment, then first Alipay will receive payment request. Then it initiates the protocol to the network, saves the information to the database, and forwards the request to the bank. When the Alipay account shows that the dection is successful, it will have to be connected to the bank through the Internet. Then the buyer will confirm receipt after receiving the goods, so that the buyer will dect the money before transferring to the seller's account. Not only is the transaction process too cumbersome and complex, it is clear that the transaction between the two parties has to go through a series of links. More importantly, once the intermediate payment link collapses, the whole transaction will stop, and the subsequent operation is really troublesome
in fact, the popular explanation is that when I want to buy something, I give the money to the middleman and ask him to help the seller. If the middleman makes any mistakes, it may lead to the situation that the money can not be recovered and the goods can not be obtained
is there any way to simplify the transaction process and improve the transaction efficiency? Yes, the current hot blockchain technology and digital currency payment can better solve the above problems:
blockchain has become one of the hot topics in the past two years. Blockchain can replace the existence of these third-party services:
first, blockchain can not be tampered with. Every transaction will be distributed to each block for record keeping, Then use cryptography to verify, any malicious damage or record deletion will be found, so the whole process of shopping will be seen. Blockchain strengthens the trust, traceability and transparency in the transaction, making our transaction faster and more convenient<
the second is the unique payment characteristics of digital currency:
the decentralization of digital currency can eliminate the intervention of the third party, and there is no need to worry about the problems of the third party, resulting in the whole transaction payment process can not continue
the point-to-point transmission of digital currency saves the time link in the whole payment process and realizes fast payment, so that both parties can receive money quickly and save time
openness and transparency of digital currency: except for cash transactions, all transactions based on online payment are just a series of numbers, and all transactions of digital currency are open and transparent. You can check the transaction records of all payments, which can ensure the security of the overall commodity payment
and like China's booming WeChat, Alipay and other payment platforms, cross-border payment has been realized, but there is a problem that fees will be more expensive than domestic payments, and the settlement cycle will be longer than domestic. In general, efficiency will be slow, time is long, and hand renewal is expensive. Digital money will make traditional transactions "no longer traditional". That will also make cross-border payment more efficient: digital currency is not subject to the "constraints" of any country or bank. Based on blockchain technology, it can just bypass this centralized system with low handling charges, and its point-to-point transmission transaction characteristics can effectively improve the current problems of long-time and high cost of cross-border payment
the times have been developing, and the way of life is constantly improving. Online shopping and payment are born from our development, with both advantages and disadvantages. Then we will try our best to push everything in a better direction
digital currency is on the rise. Although the current digital currency is not perfect, many countries have begun to use digital currency as a payment method. Due to the various characteristics of digital currency, bitcoin, Ethernet, Las Y2, QTP (wechat ID: yingbivc), ASEC and other digital currencies are being actively used. They can not only simplify the traditional online payment transaction process, but also circulate payment around the world and rece exchange rate issues such as handling charges. Don't just look at digital currency with one eye. Maybe in the near future, it will open the era of digital currency full payment!

6. The difference between code chain and blockchain:
blockchain originates from the underlying technology of bitcoin and is the blockchain technology of Internet. IP is connected by blockchain technology to form distributed accounting. It is not easy to tamper with and decentralize
code chain technology is the code chain technology of the Internet of things, which superimposes the Internet of things IDS one by one in a two-dimensional way to form personal records. The application of "code chain" technology will bring more efficient link forms of "people to people", "people to things" and "things to things"
Introction to code chain:
"code chain" refers to a "two-dimensional code chain" formed by using a smart phone to aim at the "two-dimensional code" and "scan", that is, to "generate a new two-dimensional code containing the scanner's DNA" and access to the "service". The whole process can be traced, supervised and managed
"code chain technology" is the most widely used two-dimensional code "scan" payment technology
code chain technology can realize more efficient link form of people to people, people to things and things to things
Introction to blockchain:
blockchain is an important concept of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
the difference between code chain digital currency and blockchain digital currency:
the difference between "code chain digital currency" based on code chain technology and the existing blockchain digital currency is that "code chain digital currency" is based on the control of property rights, and uses "intelligent two-dimensional code" as the medium to transform the contracts of various instry chains into divisible, tradable, transferable, exchangeable Traceable "smart contract" and real right exchange within the code chain alliance. In the code chain monetary system, "intelligent two-dimensional code" means "SGR". That is to say, each commodity corresponds to a "smart QR code", and this "QR code" represents the "special reference property" of the commodity. Through special reference to the exchange of property rights, the exchange of goods (barter) can be realized. This two-dimensional code, which represents "special mention of property rights", can be used as the carrier and payment means of digital currency at the same time, and payment can be completed through "two-dimensional code scanning".
