Digital currency series

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. If a few years ago, maybe I would not hesitate to say bitcoin, but in recent years, the development of bitcoin is a bit unsatisfactory. Today's latest information report also shows that the price of bitcoin has fallen below $10000. If you only hold bitcoin, it may not be good news, but it has no effect on the virtual currency contract transaction, which can be traded in both directions

if you don't have a lot of spare money on hand, it's a good choice to invest in virtual currency at this time. With a threshold of several hundred yuan, new users of the realm can also get a $50 coupon, which will not affect our lives, but also bring considerable benefits<

the investment mode that can also trade is not only suitable for young people, but also for the elderly, because it does not require you to have much deep investment experience, as long as you know how to judge the direction of price rise and fall, and the trading time is relatively free, 24 hours a day can be operated at any time.

3. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008. It is a kind of P2P digital currency. Bitcoin is not issued by specific monetary institutions. It is generated by a large number of calculations based on specific algorithms. At present, bitcoin can be bought and sold on mainstream platforms such as coin security, fire coin, bitewang (free of charge) and so on.

4. Blockchain ≠ digital currency
cryptocurrency (digital currency) is just a proct of blockchain technology. Blockchain is a distributed ledger technology, and cryptocurrency is just a token of a blockchain project

5. Blockchain is an important concept of bitcoin, which 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 the information of a batch of bitcoin network transactions, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block. Digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form
