Ethereum ppt

1. In popular words: if we assume that the database is an account book, reading and writing the database can be regarded as a kind of bookkeeping behavior. The principle of blockchain technology is to find the fastest and best bookkeeper in a period of time, and then send this page of information of the account book to everyone else in the whole system. This is equivalent to changing all records in the database and sending them to every other node in the whole network, so blockchain technology is also known as distributed
ledger
bitcoin, lightcoin, Ethereum, a smart contract platform, and decent, a distributed content publishing platform, all use blockchain technology.

Financial instry

blockchain should be the most widely used in the financial instry

, for example, OMG (young model currency) in May 2017, omise announced that it was launching an electronic wallet with Alipay to integrate Alipay payment solutions into its own payment service suite, helping local e-commerce businesses in Thailand to accept online payment transactions from China tourists. p>

another example is PPT, which is a bill financial transaction system based on blockchain

gambling

the gambling instry probably entered the blockchain last year. Why does gambling favor blockchain? Blockchain provides a relatively fair guessing system. Why is it relatively fair? As can be seen from the previous introction, blockchain can not be tampered with or forged

for example, wicc is a rich application scenario that can realize asset issuance, guessing application, right traceability, mutual insurance, decentralized exchange, cross-border settlement, etc

for example, the STX stox application is designed to provide the full functionality of the forecast market application without any central server. Forecasting the market requires functions such as event planning, market making, providing information and analysis to traders, reporting event results, and of course collecting and paying

I believe that if the current lottery instry is set up on the blockchain, people's purchasing enthusiasm will be higher and higher, because too many insiders make people give up

Internet of things

there are still many applications of the Internet of things in the blockchain, because the traceability and timeliness of blocks are very suitable for this instry

for example, data is the concept of Internet of things, which is a decentralized P2P network. The data source can connect with any node in the whole network, and then publish the data, and the network will immediately send it to the subscriber. Horizontal scalability is achieved through fragmentation mode. This is very important for the timeliness and accuracy of Internet of things applications

game instry

for example, GTC (g coin) is a decentralized digital asset based on Ethereum erc20 issued by game.com, and G coin is committed to becoming the general digital currency standard of the global game instry

for example, mana is a distributed shared virtual platform. On this platform, users can browse and discover content, and interact with other people and entities. Users can also claim the ownership of virtual territory through the land ledger based on blockchain. The territory is demarcated by rectangular coordinates (x, y), and its owner can decide the content published on the territory, including interactive systems from static 3D scenes to games

there are many other instries. The great emperor did not list them one by one, but listed several representative instries. What is the point? It shows that blockchain is definitely not only the transaction of currency, it is a proct of the era change with real landing project and real practical use

in fact, the development of human society is just like the blockchain, which is irreversible and unstoppable. In my opinion, sooner or later, the blockchain will enter into thousands of households, no matter the ox or bear, hold the value currency in hand, and tonghuashun has begun to offer digital currency, which shows that the society is accepting it step by step, and the power of social development can not be blocked by any country or person

Artificial intelligence is a branch of computer science, not a single discipline, image recognition, natural language processing, robotics, language recognition, expert system and so on, each research is full of challenges. Interested in artificial intelligence, but unable to determine the specific direction, how to understand the status and research areas of artificial intelligence

the author recommends four undergraate general books. For most people, the reading difficulty is not high, the formula and theory are few, the content is interesting, and they can read on; The information is fresh and complete. It's better to have some reading value and deep thinking. The book list is not long. It's only for the introction of popular science

1, super intelligence

2, our last invention: artificial intelligence and the end of human era

3, intelligent era

4, artificial intelligence: the grasp of national artificial intelligence strategic action

6. If century Jiayuan wants a mobile phone number, 80% of them are cheaters. This website will try to use some member information to cheat other members' mobile phone numbers. Once it wants a mobile phone number, it will call you and ask if you need matchmaker one-to-one service. My friend signed up for this website and left an old number. The new number was left to a person with good information. However, it didn't take long for this person's information to be closed. It's estimated that my friend's mobile phone number will be hacked. After that, some website staff called to ask whether to provide one-on-one service. My friend has bought a diamond member, As a result, they still cheat others by immoral means. So don't leave any numbers.

be alert to the "air currency" separated from the support of physical projects

What's more, as long as the capital is willing, even if there is no project behind the air currency, there is the possibility of a sharp rise in the price. Obviously, once there is a problem with the "air currency", it is really like the air, invisible and invisible

it is the key for investors to strengthen their risk awareness and stay away from "air currency". Although virtual token has a certain value, the era of decentralization has not yet come. What is the difference between it and illegal fund-raising? Cooling down the market sentiment of "air currency" is an urgent task
