『一』Introduction to 1.3 billion virtual pet cats
On the 10th, the online version of the British "Sunday Times" quoted the sales data of the CryptoKitties website and reported that since the game 12 days Since its launch, 70,000 CryptoKitties have been traded, with a transaction volume of more than 11 million US dollars, approximately 72.82 million yuan.
This phenomenon has triggered a lot of discussion. Some people believe that this is not the first time that this kind of electronic pet has appeared. This time it is just equipped with the concept of "blockchain", and such a high price is just a bubble;
『二』Blockchain Consensus algorithm in technology
We have shared some explanations and analysis of knowledge points about blockchain technology with you many times. Today, in the Huilongguan Java course, we will learn about some basic definitions and characteristics of the consensus algorithm in blockchain technology.
A brief look at the blockchain
The chain in our general ideology is an iron chain, made of iron. One link after another. Figuratively, the blockchain can be understood this way, except that it is not made of iron, but connected by blocks with a certain data structure. This is a simple prototype
< /p>
Popular explanation of consensus
The so-called consensus, in layman’s terms, means that we all agree on the understanding of something. For example, we have daily meetings to discuss issues, or we can judge whether an animal is a cat. After looking at it with the naked eye, we feel it looks like a cat. If it meets the characteristics of a cat, then we think it is a cat. Consensus is a rule.
Continuing with our meeting example. Participants in the meeting discuss and solve problems through meetings.
Compared with the blockchain, miners participating in mining use a certain consensus method (algorithm) to make their own ledger consistent with the ledgers of other nodes. The deeper meaning of keeping the ledger consistent is to keep the block information in the chain consistent.
Why is consensus needed? Is it possible to not need it? Of course not. Without the rules of consensus in life, everything will be chaotic. The blockchain loses consensus rules, and each node does its own thing, losing its consistent meaning.
The corresponding relationship between these two examples is as follows:
Meeting people = mining miners
Meeting = consensus method (algorithm)
Talk about solving problems = make your own ledger consistent with the ledgers of other nodes
If you don’t understand the concept of a node, please first understand it as a miner. A node contains many training roles, and miners are one of them.
Consensus algorithm
Currently in the blockchain, nodes allow their own ledgers to match those of other nodes.There are several consensus methods (algorithms) that maintain consistency:
PoW, represented by Bitcoin (BTC)
Disadvantages:
The emergence of mining pools violates the original intention of decentralization to a certain extent, and also makes 51% attacks possible, affecting its security.
There is a huge waste of computing power. Look at the mining pool that consumes a lot of electricity resources. As the difficulty increases, what is mined is not enough to pay the electricity bill
< /p>
PoS, represented by Ethereum (ETH), transitioning from PoW to PoS
Disadvantages:
< p>The cost of attackers attacking the network is very low, and they can compete if they own tokensIn addition, the probability that nodes with a larger number of tokens will obtain accounting rights will If it is larger, the network consensus will be dominated by a few wealthy accounts, thus losing fairness.
『三』 How to define blockchain and what are its application scenarios
Many people now think that blockchain is a universal technology , omnipotent, somewhat mythizing blockchain technology!
Regarding the definition of blockchain technology, American scholar Melanie Swann defined blockchain technology as an open, transparent and decentralized technology in her book "Blockchain: A New Economic Blueprint and Introduction" database.
Definition of Blockchain: Narrow VS Broad
As for the application scenarios of blockchain technology, it is natural to combine the differences between blockchain and other technologies. In terms of system characteristics.
Blockchain technology features include:
Blockchain is a global A database storage system that can be operated collaboratively in various places is different from traditional database operations where read and write permissions are in the hands of a company or a centralized authority (a characteristic of centralization). Blockchain believes that anyone with the ability to set up a server can participate. Nuggets from all over the world have deployed their own servers locally and connected to the blockchain network to become a node in this distributed database storage system; once joined, the node enjoys exactly the same rights as all other nodes and obligations (decentralized, distributed characteristics).
At the same time, people who provide services on the blockchain can perform read and write operations on any node in the system. In the end, all nodes around the world will complete the process again and again according to a certain mechanism. Synchronize in sequence to achieve complete consistency of data in all nodes in the blockchain network.
At the beginning of this year, the term blockchain began to enter everyone’s lives. From national leaders to aunties who dance square dances, everyone knows this term. This termThe widespread popularity of the word was brought about by Bitcoin.
As we all know, the first few dozen bitcoins could only be exchanged for one pizza. At its peak, it was more than 20,000 US dollars each, which has skyrocketed by more than a thousand times, which has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering into everyone's life, and many people have joined the ranks of currency speculation. I often hear people say that if you buy the right currency a hundred times, a bicycle will become a sports car, and one coin will turn a young model. You can imagine how many of them are involved. Attractive.
Since 2008, various games applying blockchain technology have also become popular, such as development games (Network Letts Dog, 360 Block Cat), mining games (NetEase Planet, Virtual Earth, Gongxinbao), these are attracting everyone to join in the name of blockchain, and of course there are some that are really reliable, which requires everyone to identify them carefully.
Blockchain is a distributed ledger (database) that connects data blocks in an orderly manner and cryptographically ensures that it cannot be tampered with or forged. technology. In layman's terms, blockchain technology can achieve openness, transparency, non-tampering, non-forgery, and traceability of all data information in the system without the need for third-party endorsement. As an underlying protocol or technical solution, blockchain can effectively solve the problem of trust and realize the free transfer of value. It has broad prospects in the fields of digital currency, financial asset transaction settlement, digital government affairs, and certificate deposit and anti-counterfeiting data services.
Digital currency
After experiencing physical objects, precious metals, banknotes and other forms, digital currency has become the development direction of the digital economy era. Compared with physical currency, digital currency has the characteristics of easy portability and storage, low circulation cost, convenient use, easy anti-counterfeiting and management, breaking geographical restrictions, and better integration.
Bitcoin technically implements an electronic cash system in which both parties to the transaction can directly transfer funds to each other without the need for third-party transfer or arbitration. In June 2019, the Internet giant Facebook also released a white paper on its cryptocurrency Libra. Whether it is Bitcoin or Libra, the underlying technology they rely on is blockchain technology.
my country began the development of central bank digital currency as early as 2014. my country's digital currency DC/EP adopts a two-tier operating system: the central bank does not directly issue digital currency to the public. Instead, the central bank redeems the digital currency to various commercial banks or other legal operating institutions, and then these institutions exchange it for public supply. its use. In early August 2019, the central bank held a video conference on work for the second half of the year. The meeting called for accelerating the pace of research and development of the national legal digital currency.
Financial asset transaction settlement
Blockchain technology naturally has financial attributes, and it is causing disruptive changes in the financial industry. In terms of payment and settlement, under the blockchain distributed ledger system, multiple market participants jointly maintain and synchronize a "general ledger" in real time, payment, clearing, and settlement tasks that now take two or three days can be completed in just a few minutes, reducing the complexity and cost of cross-bank and cross-border transactions. At the same time, the underlying encryption technology of the blockchain ensures that participants cannot tamper with the ledger, ensuring that transaction records are transparent and safe. Regulators can easily track transactions on the chain and quickly locate high-risk capital flows. In terms of securities issuance transactions, traditional stock issuance has long procedures, high costs, and complex links. Blockchain technology can weaken the role of underwriting institutions and help all parties establish fast and accurate information exchange and sharing channels. Issuers handle issuance on their own through smart contracts, and regulatory authorities With unified review and verification, investors can also bypass intermediaries and conduct direct operations. In terms of digital bills and supply chain finance, blockchain technology can effectively solve the financing difficulties of small and medium-sized enterprises. It is difficult for current supply chain finance to benefit small and medium-sized enterprises in the upper reaches of the industrial chain, because they often do not have direct trade relations with core enterprises, and it is difficult for financial institutions to evaluate their credit qualifications. Based on blockchain technology, we can establish a consortium chain network covering core enterprises, upstream and downstream suppliers, financial institutions, etc. The core enterprises issue accounts receivable vouchers to their suppliers. After the bills are digitized and uploaded to the chain, they can be uploaded to the supplier Transfer between them, each level of supplier can realize the corresponding amount of financing with the digital bill certificate.
Digital Government Affairs
Blockchain can make data run and greatly streamline the service process. The distributed technology of blockchain can allow government departments to be centralized on one chain, and all service processes are delivered to smart contracts. As long as the service personnel pass the identity authentication and electronic signature in one department, the smart contracts can be automatically processed and transferred, and the subsequent steps can be completed in sequence. All approvals and signatures. Blockchain invoice is the earliest application of domestic blockchain technology. The tax department launched the "Tax Chain" platform for blockchain electronic invoices. The tax department, the issuer, and the payee join the "Tax Chain" network through unique digital identities, truly realizing "instant invoicing for transactions" and "instant reimbursement after invoicing" - in seconds Level invoicing and minute-level reimbursement accounting greatly reduce tax collection and management costs, and effectively solve problems such as data tampering, over-reporting of one ticket, and tax evasion. Poverty alleviation is another practical application of blockchain technology. Utilize the characteristics of openness, transparency, traceability, and non-tampering of blockchain technology to achieve transparent use, precise investment, and efficient management of poverty alleviation funds.
Evidence-based anti-counterfeiting
Blockchain can prove the existence of a file or digital content at a specific time through hash timestamps, and it is open, non-tamperable, and traceable. It provides perfect solutions for judicial forensics, identity certification, property rights protection, anti-counterfeiting and traceability, etc. In the field of intellectual property, the digital signature of blockchain technology and on-chain certificates can confirm the rights of text, pictures, audio and video, etc., and create and execute transactions through smart contracts, allowing creators to regain pricing power and preserve data formation in real time. The evidence chain covers the three major scenarios of rights confirmation, transaction and rights protection. In the field of anti-counterfeiting and traceability, blockchain technology can be widely used in food, medicine, agricultural products, alcohol, luxury goods, etc. through supply chain tracking.Luxury goods and other fields.
Data services
Blockchain technology will greatly optimize existing big data applications and play a huge role in data circulation and sharing. In the future, the Internet, artificial intelligence, and the Internet of Things will generate massive amounts of data. The existing centralized data storage (computing model) will face huge challenges. Edge storage (computing) based on blockchain technology is expected to become a future solution. Furthermore, the non-tampering and traceability mechanism of blockchain ensures the authenticity and high quality of data, which becomes the basis for all data applications such as big data, deep learning, and artificial intelligence. Finally, blockchain can realize multi-party collaborative data calculations while protecting data privacy, and is expected to solve the problems of "data monopoly" and "data islands" and realize the value of data circulation. In response to the current blockchain development stage, in order to meet the blockchain development and application needs of general business users, many traditional cloud service providers have begun to deploy their own BaaS ("Blockchain as a Service") solutions. The combination of blockchain and cloud computing will effectively reduce enterprise blockchain deployment costs and promote the implementation of blockchain application scenarios. In the future, blockchain technology will also play an important role in many fields such as charity, insurance, energy, logistics, and the Internet of Things.
The three words "blockchain" were completely ignited during the Spring Festival that just passed. The limelight overshadowed everything. Some people said that this was the arrival of a new era. The past It has become a classic, and some people say that it is all hype and is ultimately a bubble.
In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, the third-party electronic signature platform eShanbao revealed the latest progress of blockchain applications to NewSeed.
Currently, blockchain technology is mainly used in e-signing products for certificate deposit and certificate issuance. The application scenarios include copyright protection and online signing. , web page forensics, phone recording, email storage of evidence, etc.
Take the rights protection of online works as an example. Since online rights protection generally adopts the method of collecting evidence after the fact, real-time confirmation of rights is not carried out in the process of evidence generation, so the entire confirmation process is difficult. The copyright process is time-consuming, difficult and costly to obtain evidence, and extremely difficult to prove and trace the source. It cannot meet the characteristics of rapid dissemination and large quantity of online works.
eShanbao's new intellectual property protection solution based on timestamp + blockchain starts from the user's real-name authentication and solidifies the information generated in the process in real time. Electronic data, and through the time source service synchronized with the National Time Service Center, online works are stamped with legally valid timestamps to prove that electronic files have not been tampered with in a certain period of time. Blockchain technology can establish point-to-point trust in the network and ensure that all blockchain nodesIt can record complete copyright confirmation and transaction records, and can trace the source, truly realizing anti-repudiation and anti-tampering, and realizing a distributed trust infrastructure.
Founder and CEO Jin Hongzhou believes that the application of decentralized blockchain technology has greatly improved the efficiency of data storage and certification, and The credibility of the identity of the parties reduces the cost of trust, but it cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, it can provide users with real-time and reliable Confirmation plan.
Next, e-Shanbao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage, Issuing certificates is only a relatively superficial application based on blockchain technology. It is the first step to implement blockchain technology, and the realization of real smart contracts is the second step. "Smart contracts cannot simply be understood as electronic contracts. They refer to a process, from the conclusion of the contract to the confirmation to the final execution." Jin Hongzhou explained.
From a technical perspective, blockchain is not a brand-new technology, but a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, and smart contracts. Specifically, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner.
Due to its advantages such as "decentralization", "distributed data storage", "traceability", "anti-tampering", and "openness and transparency", blockchain technology can effectively solve data problems. By establishing a trustworthy data management environment, we can prevent and avoid various data management problems such as data fraud, tampering, and loss, and promote the efficient sharing and application of data. In the process of practice and exploration, the application scope of blockchain technology continues to expand, especially in the field of public resource transactions, and continues to empower public resource transaction management services.
Facilitate transaction data sharing and transaction witnessing
Facilitate transaction data Share
Currently, the data of different trading centers are not interoperable, and the subject information of different trading centers needs to be entered repeatedly. It is difficult to verify the off-site performance provided by the bidders during the bid evaluation process. It is difficult to troubleshoot the same person repeatedly serving as project manager. Issues such as low cost of breach of trust. Establishing a cross-regional subject database based on blockchain can well alleviate the above problems.
The distributed ledger feature based on the blockchain can effectively ensure the real-time or quasi-real-time sharing of data, and can reduce the repeated entry of subject information; the use of blockchain information that cannot be tampered with can ensure the data circulation process on the chain. authenticity, the performance of bidders within the regional alliance is directly taken from the on-chain dataMake false performance invisible. At the same time, the sharing of bidding behavior data through the blockchain provides a data basis for the development of "joint punishment of dishonest enterprises".
Blockchain-based transaction witness
"Guiding Opinions on Deepening the Integration and Sharing of Public Resource Trading Platforms" ( The State Office Letter [2019] No. 41) pointed out the need to optimize services such as witnessing, venues, information, files, and expert extraction. However, at present, public resource transaction process witnessing is mainly based on manual on-site witnessing, which has limited witnessing intensity, high occupation of human resources, and limited witnessing effect. Due to its centralized characteristics, the traditional digital witness system is prone to data tampering, and the data is easily damaged or lost during the storage and migration process, which has certain flaws in terms of security and usability.
Utilize the distributed, difficult to tamper, and traceable characteristics of the blockchain to solidify and store the data generated in each transaction link, and accurately record the data generated through time stamp technology, summary algorithm, and electronic signature technology. Time, content, data source. According to the technical characteristics of the blockchain, simple structured data can be directly saved on the blockchain. For unstructured layout files, videos, audio and other large files, the summary information and original files can be saved through the blockchain. Save via a distributed file storage service. When there are disputes or problems in a transaction, the blockchain can provide a set of credible transaction process data and clarify the responsibilities of all parties involved in the transaction. Achieve the goals of risk prevention and control in all aspects, traceability of the entire process, and improvement of all-round services.
Promote the rationalization of electronic guarantee rates
Promote financial services and corporate financing for bidding companies
Promote the rationalization of electronic guarantee rates
At present, electronic bidding deposit guarantee letters have certain applications in the field of bidding, solving the problem of bidding deposit funds for bidding companies. Occupancy issues. However, because financial institutions currently do not have reliable historical bidding behavior data of bidders, they are unable to judge the default risks of different bidders. As a result, the guarantee services charged to bidders adopt fixed rates, which makes a small number of bids with high default risks The cost of personal guarantee is allocated to most bidders with low default risk, which increases the guarantee rates for most bidders to a certain extent.
At present, it is up to the bidder to choose whether to use an electronic letter of guarantee, and the rate is the main choice basis for the bidder. If the bidder performance records are shared through the blockchain and the performance risks of different bidders are analyzed, it will be Different bidders provide different guarantee rates, which not only reduces the risks of financial institutions, but also reduces the use costs of most bidders and promotes the use of bid guarantees. To a certain extent, it can also encourage bidders to abide by their promises and maintain the order of the bidding market. .
Promote bidding corporate financial services
The bidding behavior of bidders is scattered in various trading centers, and the data is simply aggregated into a centralized Information systems are at risk of data tampering (untrustworthy), and valuable bidder transaction behavior data cannot be gathered and shared safely and reliably. Through blockchain technology, bidders from multiple trading centers are gathered, and historical bidding, winning bids, defaults, violations and other behavioral records provide data support for financial institutions to evaluate the bidders' credit in the bidding sub-sector.
Solving the financing problems of successful bidders
Traditional corporate loans mainly evaluate the company's solvency: collateral, audit There are requirements for accurate financial statements and sustained profitability, but most small and medium-sized enterprises cannot provide these "proofs" at all. Difficulty and expensive financing have become problems faced by many small and medium-sized enterprises in bidding activities. Using the methods of the past will no longer work. To solve the financing difficulties of small and medium-sized enterprises, we can only rely on new technologies and new tools. With the help of the non-tamperable characteristics of blockchain, primary business data from multiple trading centers are gathered, and big data analysis technology is combined to build a portrait of a credible bidder. On the one hand, it improves the risk control level of financial institutions and taps high-quality bidding companies. On the other hand, it lowers the loan threshold for bidding companies and optimizes the service experience.
Drawing on the supply chain finance model, the bidder is a core enterprise with good credit in government departments, national enterprises and institutions, and the winning contract obtained by the winning bidder as a supplier is considered by financial institutions to be a high-quality asset. Apply for a loan from a financial institution. Under the traditional paper-based model, there is a risk of order and contract fraud and the process is cumbersome. Centralized information systems require operators to have strong authority. The distributed ledger and difficult-to-tamper characteristics of the blockchain will help solve the above problems. The contract signing between the tenderer and the bidder and the subsequent financial service links will be realized on the blockchain, which not only solves the problem of data trustworthiness but also reduces the risk of corruption. The entire system relies on a centralized authority.
Through further analysis, we found that credit sales are currently prevalent among domestic enterprises, and the upstream suppliers of the winning bidder have a large funding gap. The credit of the bidder can only be passed to the winning bidder (the winning contract cannot be split or transferred), and the upstream suppliers Business owners are unable to obtain high-quality loans from financial institutions. If the winning contract is converted into a "pass" on the chain, the "pass" can be split, and the winning bidder holding the "pass" can pay part or all of the voucher to the upstream supplier, making it discountable and financing. The "tokens" on the chain can be split and transferred from first-level suppliers to second-level (and multi-level) suppliers, thereby allowing core enterprise credit to be transferred to multi-level suppliers. The shortage of funds from suppliers due to credit sales has been solved, improving the business environment; through value transfer through the blockchain, the financing cycle has been greatly shortened; the cost of supplier loans has been reduced, which will help reduce the production costs of raw materials or intermediate products, and ultimately Increase bidders' profit margins and indirectly reduceTenderer's costs.
Regarding blockchain, we can imagine a decentralized management model and technical processing method.
Let me give you an example. There are five people in your family, and they have never been able to figure out how to arrange work and handle family relationships.
So, you and your family discuss it together and simply use voting to solve the problem.
Then this way of voting to solve problems can be called the most elementary blockchain.
Decentralization solves problems.
What application scenarios can blockchain have?
In fact, many of our families and many organizations use blockchain management forms every day
However, this kind of blockchain application for organizational relationships cannot produce Economic Value.
What are the economic applications of blockchain?
The first type is used for tax deposit certificates, bank transfers, etc.
Make full use of the traceability function of the blockchain so that all records can be retrieved and queried at any time
The second type is applied to enterprise operation and management
Enterprises using blockchain management can better solve the problems of enterprise development and allow enterprises to Able to develop faster and make more money.
Summary: The application scenarios of blockchain include taxation, bank transfers, etc., and can also be applied to business operations.
The characteristics of blockchain are distributed accounting and decentralization, but the ultimate goal is to make people get along more equally. Technology is meaningful only when it serves human values, and technology that meets human value needs will develop. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.
Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.
In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.
At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.
Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.
Currently the most popular application linesThe industry is the financial industry.
An application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to fully trace the origin of some of the products they sell. Consumers can trace the origin of the purchased products. There are also many blockchain applications in the digital advertising industry. Since traffic fraud in digital advertising causes losses of tens of billions of dollars every year, there are already blockchain application projects based on digital advertising, such as DCAD, which is based on blockchain. The digital advertising application of blockchain technology mainly solves the problem of traffic fraud
In the future, as the application of blockchain technology becomes more mature, it will be applied in many industries, creating a new ecosystem based on technological trust. Mode
What is blockchain If you explain blockchain in non-technical terms, blockchain is a place where data is stored. However, the data stored in the blockchain is safe and reliable and does not need to be managed by anyone. Therefore, in the Internet, a place where data and information are exploding, having such a place will be like a magical treasure land.
If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:
Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.
If there are any deficiencies, you are welcome to comment and correct me.
In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.
The two parties involved in the transaction do not need to know who the other party is, nor do they need a third party for trust endorsement. They only need to trust a common algorithm to establish mutual trust and conduct direct transactions.
Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire transaction network has changed from a star structure to a point-to-point P2P structure.
In the future, blockchain will be used in many fields and will have a great impact on human life. . It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.
1. Cloud storage
This is a calculation of the amount of data currently stored in clouds on the Internet. Google has the largest amount, which is 8,000PB. So what if we share the idle data on the Internet?
Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15.72864 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.
2. Medical aspects
Using blockchain technology to save personal medical records also retains personal medical historical data, which can be used when seeing a doctor or planning for your own health in the future. Historical data can be called directly. These data are highly private, and the use of blockchain technology also helps protect patient privacy.

『五』 What is "Blockchain Cat Raising" and how to play it (very detailed tutorial)
This time, the cat is in the area again The blockchain world has reached a climax.
In a few days, "blockchain cat raising" has become a hot topic in the currency circle.
CryptoKitties is the first virtual pet game that uses blockchain technology and runs on the Ethereum network.
Her appearance has a certain historical significance, and she has become the most popular project on the Ethereum blockchain.At one time, it accounted for 20% of the entire Ethereum traffic. The market has reached millions of dollars in transaction volume and is still growing rapidly...
The concept is simple. You use Ethereum to buy a cat. Each cat is unique. As long as you don't sell it, it is 100% owned by you and cannot be copied or destroyed.
The fun part is that you can go to the market to find cats to breed with, or you can buy a cat, match two of them, and the resulting kitten will be yours.
Each kitten extracts a certain sequence from its parents and combines it. Whether it is coat color, markings, pupils, hairstyle, expression, tail and other characteristics, they are all random. There are 4 billion types in total. Possibility of change. Then you can sell your cat on the market, and you set the price yourself.
Another point is that every 15 minutes, a gen 0 creation cat will be born. Its price is equivalent to the average price of the latest 5 cats sold, plus an increase of 50%. . Of course, Genesis cats are very popular. After all, they are virgins and they give birth to kittens the fastest.
Isn’t this a bit like our story of chickens laying eggs and eggs laying chickens, and our descendants are endless?
Of course, having a baby takes time.
The birth of a kitten has always been from fast to slow~slow~slow~, and the gap ranges from one minute to a week.
The shorter the time it takes for your cat to give birth, the better. This allows the newborn CryptoKitties to be sold quickly and continue to breed. This also means an increase in income.
The more babies you have, the longer the cat’s cooldowns will take, and the birth rate will also slow down.
Another interesting thing is that giving birth to kittens is a complex and random breeding system, which means that there are always some mutant attributes (attributes) appearing in it, and these become collectibles or in-demand items. .
1. Enter the official website of CryptoKitties: cryptokitties.co and click sign in to jump to the registration page. You need to install the Ethereum light wallet MetaMask plug-in on your chrome or firefox browser. (This process needs to be learned. There are three ways here. Do it as you like, guest. Password: 1rjo)
2. Click on the Mertamask plug-in to install it.
3. Accept the terms and enter your password.
4. You must remember the generated 12 English word passwords. together withSave the jason file together.
5. Then the wallet creation is completed. Enter the cryptokitties.co website to see your account, set your name, email, etc.
Method 1: If you have ETH in other Ethereum wallets, such as imtoken, you can directly transfer it to your CryptoKitties address.
Method 2: Two of the three OTC Bitcoin exchanges mentioned in this article: Coincola and bitcoinworld both support ETH transactions, and you can also transfer them directly.
Method three: It is the coinbase recommended by Matamask, but it shows US only.
1. Go to the marketplace to find the cat you like (as shown below).
2. After you like it, click buy now.
The details page shows the cat’s detailed information, serial number, and price trend chart (price over time in 1 day or 2 days) Continue to increase or decrease), the price to buy now, and the cooling time for giving birth to kittens, etc.
3. After clicking ok, buy this kitty, matamask will pop up to display the detailed estimated cost. If there are no results, maybe your mining fee is not enough, or the cat is sold. Try more. The max transaction fee shows the maximum transaction fee, which is generally not reached. Just wait for the transaction to be completed after the summit. To cancel the transaction, click reject.
During the transaction process, you can click on the transaction to enter https://etherscan.io to view the details. Or view historical transaction information on the ECG-like icon on the right side of the website.
4. Transaction successful! Congratulations, you have your first virtual cat. How to make more?
One way, life.
Pair up two by two. There is also a transaction fee for giving birth to kittens. The speed of birth depends on the speed of the parents.
Breed kitty gives birth to kittens;
Sell kitty sells kittens
Gift kitty gives kittens to friends
Another way is to rent.

『Lu』 Will "blockchain games + industry" become the future development trend?
There has been such talk recently, and it is possible that blockchain applications will be implemented as soon as possible It is in the field of gambling or gaming.
As for games, as there have been attempts like Blockchain Game 1.0 by E-Cat and Blockcat, there may indeed be a new generation with completely different forms.
The virtual attributes of the game itself and the increasing recognition of the virtual value of the game by users, the innate genes are suitable for blockchain transformation. We can look forward to the development trend!
The blockchain game industry is developing rapidly and the development prospects of blockchain games are good
2020-11-30
Blockchain games are games developed based on blockchain technology. They generally include strategy, development, sandbox, gambling, and card games. wait. Because blockchain can solve the shortcomings of traditional game mechanisms such as opaqueness, insecure user information, and poor liquidity of game assets, it has become a hot topic in modern Internet game development. Currently, large domestic game developers such as Tencent Games and NetEase Games have successively entered the blockchain In the field of blockchain games, we will promote the rapid development of the blockchain game industry.
According to the "2020-2025 China Blockchain Game Industry Application Market Demand and Development Opportunities Research Report" released by the New Thinking Industry Research Center, the recent In recent years, blockchain technology has been reused in the Internet and has even been promoted to the national strategic level. Therefore, the blockchain industry has developed rapidly. The global market size is expected to reach 14 billion US dollars by 2022, among which blockchain games willThere is huge growth potential. The development trend of the global blockchain game industry is roughly the same. my country's blockchain game industry also shows a rapid growth trend. The market size was US$1.7 million in 2019 and is expected to reach US$14.5 million by 2022.
Blockchain games can be divided into Ethereum games, public chain games, LinkToken games, private chain games, etc., which are based on Ethereum and public chain respectively. , private chain, Wanke Cloud and other platforms developed games. At present, most domestic blockchain games are developed based on Ethereum, but Ethereum has shortcomings such as imperfect functions, high costs, and insufficient performance. Therefore, companies in the blockchain game industry will re-establish a public chain to solve the problem of Ethereum. performance issues.
In the blockchain game industry chain, the midstream is game developers, accounting for more than half of the profits of the entire industry chain. Current blockchain game developers mainly include small groups, Internet companies (Xiaomi, Internet), and game companies (NetEase Games, Tencent Games). The profit sources of blockchain games are token income, prop fees, and transaction fees.
The downstream of blockchain games are game distribution platforms and decentralized asset trading platforms. Among them, game distribution platforms include Dapp.com, 55Play, etc., which can provide players with It provides services such as game social networking and game explanations, and at the same time provides game developers with intuitive blockchain game market performance, which is helpful for developers to understand changes in the game market. A decentralized asset trading platform can trade and sell game assets without the need for a third party. The more well-known platforms include Dmarket, OpenSea, Enjin, etc.
New Thinking industry analysts said that in the context of the rapid development of the Internet industry, the demand for blockchain technology applications continues to rise, the market scale continues to expand, and blockchain As an important market segment in the blockchain field, chain games have great potential for future development. Currently, in the blockchain game industry chain, blockchain game development accounts for a relatively high proportion of profits, and this field has greater potential for future development.
Not to mention that blockchain is currently a new player in Internet technology, games alone already have a huge market, not to mention the blockchain games mentioned by the question. ,
Currently, there are many companies on the market using games as a breakthrough in the industry. For example, Anmo Blockchain. Anmo Blockchain also uses the fishpond mining game as a breakthrough to increase user stickiness and the fun of using the application. There are many other applications like Anmo Wallet on the market.
TravelThe play itself uses social circles to spread. After all, any current project relies on traffic, and social media is nothing more than the fastest and most economical way.
So in summary, the blockchain game + industry must be a development trend in the future
Yes, the China Game Industry Conference that just ended last month, South Korea and Southeast Asia Game manufacturers and publishers have begun to issue coins through the blockchain to operate games. Chinese game companies are also operating games through blockchain points and tasks or directly issuing coins abroad.
『撒』 Why is cat raising on the blockchain so popular?
Just at the beginning of this month, a game about raising cats using the blockchain suddenly became popular around the world. As far as I know, this is a very, very simple game. If it were placed in the game application market, it would definitely sink into the bottom immediately. To put it bluntly, this is a cat-raising game of buying, breeding, breeding, and purchasing cats.
But why does such a simple development game cause a craze all over the world? I think it’s definitely not because of the fun of the game and the cuteness of the images.
The most important point is that this game is profitable.
Players can pay to buy cats, pay to give birth to kittens (a small fee), or borrow other people’s cats to give birth to kittens (a little more); then they can sell their own cats to breed and give birth to kittens, or they can sell them Earn uncapped profits directly.
Cats are sold by auction on the website. The currency of the transaction is Ethereum, which can be exchanged for cash on foreign exchanges. Therefore, on the premise that users can continue to consume (give birth to kittens) and trade (purchase cats), blockchain cat petting becomes an asset that can generate cash flow returns.
Secondly, this kind of income is somewhat speculative.
The setting of blockchain cat care is that two cats can give birth to kittens, but each cat has several factors, including seniority, genetic tags, etc. Gene tags represent scarcity, and scarcity represents value; cats with higher seniority breed faster, so they are positively related to value.
The generation of gene tags is a black box and an opaque part of the game (most of the game is open source and disclosed in white papers). At least for now, there's no obvious analysis that points to how cats with the scarcity tag were obtained. Therefore, every time a kitten is born, a valuable and rare breed may be born, and even the program settings of the game itself may include random parameters.
This makes the entire game full of uncertainty and speculation. A speculative game, like gambling, can easily attract attention and investment.
Secondly, blockchain itself has been a hot topic in the past two years. Many people are willing to try new things. It was difficult for many people to understand blockchain technology before. Now there happens to be a simple and easy-to-use application that allows everyone to participate in the block.
Although the popularity of this game has nothing to do with blockchain technologyrelationship, but this is a very successful example of the application of blockchain technology.
