Digital currency blockchain materials

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. Bitcoin, Ethereum, bitcash, EOS, REBO, etc. are the mainstream digital currencies. They can be properly invested, and the transactions are risky. You can invest cautiously. You can search the fire coin, coin security, OK, dobby trading platforms on the Internet, and all of them can trade bitcoin. These are the relatively large trading platforms, investing in the mainstream digital currency Don't invest in counterfeit money or air money. Generally, there are operating instructions on the platform

5. Chainstore is a professional application store that integrates all the mainstream applications of blockchain and coin circle. It integrates exchanges, wallets, quotation software, tool software, blockchain information, blockchain games, instry applications, etc
different from other app stores, chainstore can not only download blockchain instry applications, but also browse the latest airdrop candy information and high-quality blockchain projects. It is an app that provides comprehensive services for the blockchain instry.

6. 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

7.

At present, the most successful application of blockchain technology is the digital currency represented by bitcoin, and blockchain also benefits from the deeper development of digital currency

instry insiders said that if a wants to send a bitcoin to B, it first needs to send a transaction request to the blockchain network, provide the addresses of a and B as well as the number of bitcoins sent, and at the same time use the private key to digitally sign the sent information to prove its identity to B. After the information is sent, the miner needs to determine the uniqueness of the transaction, the legitimacy of the address involved in the transaction, the authenticity of the digital signature and the correctness of the number of bitcoins after receiving the information sent by A

after successful verification, the transaction will be added to the block, and each block contains all the transactions in the past ten minutes. Generally speaking, each transaction must be confirmed six times before it can be recognized as a legal transaction on the blockchain. Finally, the block is chained, the transaction is completed, and B receives 1 bitcoin
