『一』What is blockchain ppt

Explained from an academic perspective, blockchain is a computer with distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. New application models of technology. Blockchain is essentially a decentralized database.
For example, if you are a woman, every time your boyfriend says something disgusting to you or promises to buy you something, you immediately record it and send it to all your best friends, classmates, Colleagues, as well as various groups and circles of friends, make it impossible for him to deny it anymore. This is called blockchain.
The core advantage of blockchain technology is decentralization. It can achieve decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Point-to-point transactions, coordination and collaboration, thus providing solutions to the problems of high cost, low efficiency and insecure data storage common in centralized institutions.
The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. , which has had a relatively large impact on the domain name industry.

『二』Blockchain treasure hunting has a new trick, everyone can win the treasure and everyone can be the villager

Following the mining crisis in June, there has been another stir in the currency circle A new wave of treasure hunts. As a leader in the blockchain insurance industry, how could CIC miss a good publicity opportunity? Its partners have also developed the Raiders of the Lost Ark activity. It is said that not only can everyone participate in the treasure hunt, but everyone can also start the treasure hunt. , and the asset security guarantee is exclusively provided by Yunbao Chain CIC. Do you want to play it and experience the addiction of being a banker? Here is the detailed gameplay of Raiders of the Lost Ark. Let’s explore it together.

How to play Raiders of the Lost Ark:

This time, the Raiders of the Lost Ark event, in which asset security is exclusively provided by CIC, is automatically calculated based on blockchain technology. When it comes to fairness and justice, we must put an end to fraud.

Treasure hunt features: Users can not only use digital currencies to participate in treasure hunts, but can also make their own bankers to initiate treasure hunts, with up to 33 participating currencies. Such as: CIC, ETH, AIDOC, QUN, DPY, LET, LRC, SEER, TRX, HIT, CMT, PST, IOST, MANA, BNB, NULS, THETA, PPT, GTC, AE, KEY, PAY, GTO, CVC, SOC, RUFF, EKT, CNMC, ELF, WIN, CAN, ABT, OMG.

1. Participate in the treasure hunt: Users use digital assets cic (or other currencies) to participate in the treasure hunt. Each time they participate in the treasure hunt, the system will determine the treasure hunt based on the user’s participation.The number of copies is assigned to the lucky number of the user. When all the lucky numbers of the product are allocated, the blockchain treasure hunting program will calculate the lucky number based on the random number of the Ethereum block height. The user who holds the lucky number will Get this product.

2. Initiate a treasure hunt: Not only can users participate in treasure hunts initiated by others, but they can also be their own banker and use their own coins to initiate a treasure hunt. After the lottery is drawn, the initiator can obtain the value of the prize. 5% as income.

3. The calculation rules are as follows:

1. When the exchange of all shares is completed, the system will record the latest block height of the current Ethereum.

2. Use the current block height + 12 as the height of the lottery block, and wait for the block with the lottery height to be generated, which takes about 3 minutes.

3. After the lottery block is generated, take the last four digits of the lottery height hash value (hexadecimal).

4. Then convert the four-digit hash value into a decimal number, and take the remainder + 1 from the total number of copies to generate this lucky number.

The above is the detailed gameplay of the Raiders of the Lost Ark activity where asset security is exclusively provided by Yunbao Chain CIC. It is common for everyone to win treasures, but this is the first time that everyone can be the banker. If you don’t want to experience it quickly, then join the CIC family quickly. You can search the Telegram channel obaoqibing to learn the details of the Raiders of the Lost Ark activity.

『三』What exactly is blockchain? Which blockchains have physical applications

What is blockchain?

Official definition: Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission consensus mechanism encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.

Vernacular understanding: A block is to package all the data generated within a time period in chronological order. Generally, the length of a block is 10 minutes, which means that within 10 minutes, all the data on the Internet will The data is packed into a complete package, and this complete data package is called a block. The blockchain links these data packages in order to form a structure, and cryptographically ensures that it cannot be tampered with or forged to form a distribution. ledger, this is the blockchain.

It seems that everyone has a preliminary knowledge and understanding of the blockchain. So whether the blockchain has any practical application in daily life, the answer is yes, the current practical application There are mainly the following aspects. Of course, I may not know some of them. Friends are welcome to leave messages to add.

Financial Industry

Blockchain should be used the most in the financial industry.

For example, in May 2017, OMG (Omise Coin) announced that it would cooperate with Alipay to launch an electronic wallet, which is part of its own payment service suite.Integrate the "Alipay" payment solution to help local e-commerce merchants in Thailand accept online payment transactions from Chinese tourists.

Another example is PPT, which is a financial transaction system for bills based on blockchain.

Gaming

The gambling industry entered the blockchain probably last year. Why does gambling favor blockchain? Because blockchain provides a relatively fair betting system. Why? It is relatively fair. As can be seen from the previous introduction, the blockchain cannot be tampered with or forged.

For example, WICC (WikiChain) can realize rich application scenarios such as asset issuance, betting applications, copyright traceability, mutual insurance, decentralized exchanges, and cross-border settlement.

For example, the STX (King of Fighters Token) stox application is designed to provide the full functionality of a prediction market application without the need for any central server. Prediction markets require functions such as event planning, market production, providing information and analysis to traders, reporting event results, and of course collection and payment.

I believe that if the current lottery industry is built on the blockchain, people will become more and more enthusiastic about buying, because there are too many insider tips that make people give up.

Internet of Things

The Internet of Things still has many applications on the blockchain, because the traceability and immediacy of blocks are very suitable for this industry.

For example, DATA is the concept of the Internet of Things. It is a decentralized p2p network. Data sources can connect to any node in the entire network, then publish data, and the network will immediately send it to subscribers. Horizontal scalability is achieved through sharding pattern. This timeliness and accuracy are very important in IoT applications.

Game industry

For example, GTC (G coin) is a decentralized digital asset based on Ethereum erc20 issued by Game Global. G coin is committed to becoming a universal number in the global game industry. Monetary standards.

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 ownership of virtual territories through a blockchain-based land ledger. The territory is demarcated by rectangular coordinates (x, y), and its owner can decide the content published on the territory, including static 3D scenes to interactive systems such as games.

There are many other industries. The emperor did not list them one by one, but listed a few representative ones. What is the purpose? It shows that the blockchain is definitely not just a currency transaction, it is a real implementation project, and it is a product of the changes of the times with real practical uses.

The development of human society is actually like the blockchain, it is irreversible and unstoppable. As far as I feel, the blockchain will enter thousands of households sooner or later. Regardless of whether it is bull or bear, hold it in your hands. Value currency, Flush has started to quote digital currency, which shows that society is accepting it step by step. The power of social development is not which country or person canblocked.

『撒』 What are the better forums or apps for sharing and learning blockchain technology tutorials

There are not a few people learning blockchain technology now. , but there are not many blockchain training institutions. There are many blockchain communities and blockchain platforms on the Internet, such as Babbitt, Zhiquchain, Golden Finance, and other platforms, which contain information, knowledge and experience, videos, blockchain project cases, etc. in the blockchain industry. Personally, I think You can buy some blockchain books and combine them with some of the above-mentioned blockchain platforms to learn, summarize experience, and practice. After a period of time, you will have a new understanding of blockchain technology.
