Blockchain lettering

1.

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

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 the information of a bitcoin network transaction, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

some areas where blockchain can be used can be as follows:

& ᦇ 9642; Smart contract; Securities trading; E-commerce; Internet of things; Social communication; File storage; Proof of existence; Authentication

&9642; Equity crowdfunding

we can compare the development of blockchain with the development of the Internet itself. In the future, something called finance Internet will be formed on the Internet. This thing is based on blockchain, and its precursor is bitcoin, that is, traditional finance starts from private chain and instry chain (LAN), bitcoin series starts from public chain (WAN), They all express the same concept - digital asset, and finally converge to an intermediate equilibrium point

The evolution mode of

blockchain is as follows:

& 9642; Blockchain 1.0 digital currency; Blockchain 2.0 digital assets and smart contracts; Blockchain 3.0: implementation of distributed applications in various instries

2. Blockchain is an important concept of bitcoin. In essence, it is a decentralized database and the underlying technology 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
blockchain is public on the network and can be queried in every offline bitcoin wallet data. The function of bitcoin wallet depends on the confirmation with the blockchain. An effective inspection is called a confirmation. Usually, a transaction needs to obtain several confirmations. The lightweight bitcoin wallet uses online confirmation, that is, it will not download the blockchain data to the device storage
many of bitcoin's competitors also use the same design, but the workload proof and algorithm are slightly different. For example, the use of proof of interest and scrypt and so on<

the concept of blockchain time stamp certificate service and proof of existence was proposed in the white paper [1] of Nakamoto Tsung, which created the first block, namely "Genesis block"< On January 3, 2009, the founder of bitcoin, Mr. Nakamoto, left an unchangeable sentence in the genesis block:
"the times 03 / Jan / 2009 Chancellor on brink of second low for banks (on January 3, 2009, the chancellor of the exchequer was on the verge of implementing the second round of bank emergency assistance)."
at that time, the British Chancellor of the exchequer, darling, was forced to consider a second attempt to relieve the banking crisis, which was the headline of the front page article of the times that day
the time stamp service and existence proof of blockchain, the time generated by the first blockchain and the events that happened at that time are permanently preserved
BTCC, a bitcoin company, launched a service "Millennium chain" in 2015, namely blockchain lettering service, which is based on the above principles. Users can use this service to engrave text on the blockchain and save it permanently
bitcoin, Laite coin, Ruitai coin and Qianjin card are all digital currencies based on blockchain technology.

bitcoin, Ruitai coin, Laite coin, dogcoin, Ethereum and other digital currencies will use blockchain technology.

4. The people's Bank of China has not issued digital currency for the time being, so there is no digital currency in China for the time being. The so-called digital currency in the market is not currency, but virtual currency (bitcoin is not currency)
1. Currency digitization and digital currency are not the same thing, so don't confuse them
2. There may be legal digital currency in China in the future, but it must be issued by the Central Bank of China
3. Bitcoin is not a currency. Currency is a credit symbol issued by the Central Bank of a sovereign country. Bitcoin is a speculative target, which is not recognized by major countries in the world.

5. It seems that a lot of people around them will conct digital currency transactions on huocoin.com and okbit. But recently, most of them have been transferred to easybtc, which has been established for quite a long time, and the handling fee is low, so it can make people earn more money

6. 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.

7. Go to the internet post bar virus bar, there are tutorials. You can also install a Kaspersky (there is a special killing tool). If you can't, go to the computer virus for help. The talents there are more professional

At the beginning of this year, before the heat wave of bitcoin was completely over, another "torrent" could not stop the fire. This is the blockchain technology that has been popular in the fields of Finance and insurance, and even in the stock trading and voting instries

this technology must be considered as a hot topic in various instries recently. Data Description: so far, in 2016, the world's largest investment projects are related to blockchain, and the investment amount has reached US $55 million and US $60 million respectively. At the end of September, the largest blockchain project in China was also announced with an investment scale of more than US $20 million

first of all, it is a new application mode that integrates distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. As we all know, bitcoin, as a global common Internet encryption currency, is developed based on the blockchain technology. The support of smart contracts on the blockchain makes the point-to-point transfer of digital assets beyond bitcoin a reality. It is not difficult to understand why the blockchain technology has become remarkable as the cornerstone of the value Internet

so why is blockchain so attractive? If today's Internet is the point-to-point transmission of information through TCP / IP protocol, it is the Internet of information, then the point-to-point transfer of value (e.g. electronic currency, electronic assets, etc.) away from the third party is provided by the blockchain technology

generally speaking, blockchain is a decentralized distributed accounting system. The nodes in the system do not need to trust each other, and maintain an account book together through a unified consensus mechanism. Each node has a complete data record. Blockchain: block transactions are connected together by cryptographic algorithm, making the whole account book transparent, traceable and tamperable

compared with the traditional credit transaction of third-party institutions, the process of blockchain in digital payment can be described as the following diagram respectively:
