Development of digital currency blockchain

1. Since 2008, Nakamoto has proposed bitcoin, a peer-to-peer cash trading system. Since then, it has entered the eyes of the world.

2. digital currency is represented by blockchain 1.0, mainly bitcoin; As a virtual currency system, the total amount of bitcoin is limited by network consensus protocol, and no indivial or institution can change or modify the supply and transaction records. Therefore, after years of successful operation of bitcoin network, blockchain is the underlying technology to support the operation of bitcoin, Its essence is a very clever distributed shared ledger and point-to-point value transmission technology. It will have a great potential impact on finance and even all walks of life
blockchain 2.0 technology application represented by smart contract
the era of blockchain 3.0 has come. Behind the operation of all walks of life, we can see the mode of collaborative operation of blockchain. Therefore, blockchain is bound to widely and profoundly change the way of human life, so the whole life service will enter the era of blockchain. In the process of Internet development, blockchain + physical instry, blockchain e-commerce and blockchain community operation can be applied to blockchain technology.

3. If you look closely at these two fields, you will find that they have begun to develop away from each other. Although digital currency is technically inseparable from blockchain, blockchain technology is not limited to digital currency. It is favored by various technical companies in terms of proct traceability, data transparency and distributed consensus. So what impact does the central bank's entry into digital currency have on the blockchain instry, It's not going to change much. At present, the ant gold clothing behind Alipay is the largest patent application company in the global block chain.
what benefits most from this is the domestic currency circle. In 2017, digital currency and related fund-raising activities were banned in China, which is quite negative in the eyes of ordinary people. In fact, the central bank's initiative to explore into cryptocurrency is the recognition of the core concept of digital currency. With this incentive, domestic enterprises will actively enter the instry and inject fresh blood into the instry, which is the most important
about this, you can see the reports of blockchain media, such as golden finance, coin easy to know column, chain news and so on.

4. 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.
