The simplest way to explain the principle of blockchain Technolo
Publish: 2021-05-17 01:06:25
1. blockchain does not belong to any instry. Blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on. In a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography.
2. Blockchain is a technical solution to maintain a reliable database collectively through centralization and distrust in the past. Now there are many procts and applications based on blockchain technology. Lifechain is a medical and nursing enterprise based on blockchain technology. You can learn about it.
3. From the perspective of data, blockchain is a kind of distributed database or distributed shared general ledger. The "distributed" here is not only reflected in the distributed storage of data, but also reflected in the distributed records of data. From the perspective of effect, blockchain can generate a set of time sequence, tamper proof and trustworthy database
blockchain has four core technologies. The first one is block + chain, which is the most core and basic technology in blockchain. The second core technology is distributed structure. The ingenious design of blockchain structure is to let every node participating in data transaction record and store all data. The third core technology is asymmetric encryption algorithm, and the fourth core technology is script, which can be understood as a programmable smart contract.

Seeing some answers to the debate on the definition of blockchain, I suddenly realize that my answer to this explanation principle has always been directed at bitcoin. There is no specific and unique answer in the instry between the definition of blockchain. Here I first summarize the characteristics of "blockchain" according to the papers I read:
1; Hash chain & quot There are several nodes participating in the system operation (distributed)
3. Reach a consensus on the consistency of basic data (consensus agreement / algorithm) through a certain protocol or algorithm
since bitcoin is currently one of the most typical and influential applications of blockchain, it will be much easier to understand how bitcoin uses blockchain before understanding other forms of blockchain applications
5. Blockchain games mainly refer to the blockchain applications in DAPP, which belong to the game category and need to interact with various blockchain public chains to a certain extent. Blockchain Games began to emerge in November of 17, with a very short history. Compared with mature games, the current playing method is quite simple. In the view of the instry, many games are even just a capital disk wrapped in the game coat
according to the classification of cryptogames, hot potato, Collectible transaction, spinach and Ponzi are the main game playing methods among the online blockchain games. The most popular games are hot potato games, including two popular games recently - cryptocelebrities and cryptocountries. There are 35 collections and transactions, ranking second, mainly represented by cryptokitties. Spinach and Ponzi are 17, ranking third, with etherroll and etheremon as the star procts
blockchain games also use a variety of themes, from cats, dogs, dragons, pigs and other animals to people, cars, countries, teams and so on
blockchain game 1.0 era
time: November to December 2017
main playing method: Collection + transaction
representative works: cryptokitties, cryptopunks
blockchain technology gives uniqueness to players' digital assets. This graally leads to the concept of NFT (non fungible tokens). The uniqueness and scarcity of people's assets in blockchain games will not change with the game itself. The concept was first applied by cryptopunks, which was launched by larva labs in June of 17. The system randomly generates 10000 punk avatars, which are put on Ethereum through smart contracts and distributed to players for free for trading
when axiom Zen studio added attributes, reproction and auction functions to NFT, cryptokitties was born. People can buy kittens with different attributes, breed with other cats, or sell their own cats through Dutch auction. Kittens with rare and unique genes are wildly sought after by people, and they get a high premium
people continue to develop on the basis of cryptokitties, adding accessories and combat functions, as well as gold digging, feeding, and looting
blockchain game 2.0 era
time: December 2017 to January 2018
main play method: Ponzi like
masterpiece: etheremon
at the beginning, etheremon's play method was very simple and crude. After a player bought a pet, as long as someone bought the same pet, the player could get a small part of eth reward. The game team quickly made a profit of about 2000 eth in a week. Then completely change the way of play, successfully transformed into a collection + combat game. This kind of Ponzi like game was quickly imitated by other manufacturers, and many imitators such as ethertanks and ethertanks appeared<
blockchain game 3.0 era
time: January 2018
main play method: fixed price, forced price hot potato mode
representative works: cryptocelebrities, cryptocountries
players buy encryption celebrities (Nakamoto, musk, etc.) and encryption countries (Japan, the United States, etc.), e to the uniqueness of assets, Subsequent players can only buy from asset owners at a higher price. The price is forced to rise, and the platform earns part of the price difference. At present, the country with the highest price is Japan, about 700 eth, and the most expensive celebrity is Elon Musk, who is worth about 200 eth
blockchain game 4.0 era
time: February 2018
main playing methods: combination of multiple mechanisms
representative works: world.mycollect, cryptocities
in the game, multi-level sales and sharing, player exploration (randomness), lottery, resource uniqueness and other playing methods are adopted. In cryptocities, for example, players can buy countries, continents and the world to "conquer.". The player who conquers the world can get 1% of the transaction volume of the continent and the country, and the player who conquers the continent can get 1% of the transaction volume of the country. In the future, players who conquer the country can get 1% of the transaction value of their subordinate cities. When exploring a new city, players have a chance to explore gems and get eth rewards
at the same time, spinach games also emerged. The high transparency of blockchains makes it easier for them to gain the trust of investors. The more famous ones are etheroll and vdice. They play simply and rudely. Players spend a certain amount of eth to bet on a certain number. When the number randomly generated by the system is less than that number, they can get profits
in addition, there are RPG (ethercraft), battle games (etherbots) and binary (ethermeng king), etc

advantages and disadvantages of blockchain games
throughout these successful cases, we find that blockchain games do have unique advantages:
high degree of trust: trust is quickly established through open source contracts, the use process is completely transparent, and the information is completely symmetrical. Fairness: data can not be tampered with and rules will never change. Assets belong to indivial players: Players' assets will not be lost with the decline of the game. Strong community attribute: blockchain itself has strong transaction and community attributes
of course, the current blockchain game is also in its infancy, with obvious disadvantages:
unable to interact in time: there are uncertain waiting time and congestion in blockchain transactions, so it is difficult to form timely interaction between players. The cost of sending instructions is high: every time the instructions are sent, gas will be consumed, while the price of eth still makes the cost of gas relatively high. Immature development environment: at present, Ethereum's virtual machine and programming language solidness are the most mature development environment in many public chains. But compared with other popular languages, it is still very immature

Gamification will boost the implementation of blockchain
in traditional desktop online games, manufacturers constantly encourage new players, leading to inflation, and the real value of all assets of a game account is often far lower than the players' investment. After the emergence of mobile games, the mode of props binding account and account binding ID card soon became popular. This also makes once the player decides to leave a game, he must give up all the virtual assets in the game. The emergence and continuous maturity of blockchain technology will make the decentralized formulation of game rules and decentralized storage of virtual assets technically feasible. The convenience of virtual assets on the chain also makes the blockchain easier to land in the game scene
cryptogames believes that the development direction of blockchain games, or the development direction of classic games (like basketball, football and chess, once the rules are determined, they will last forever), It must be "decentralized":
the rules are determined by the players through negotiation, and the players supervise each other to ensure that the game is carried out according to the rules. All the props used in the game are owned by the players themselves. If someone breaks the rules or is not happy with the game, they can go away directly. There is no centralized organizer in the game itself.
the popularity of cryptokitties has greatly promoted private wallet, Blockchain game, as an early application of blockchain, has rapidly promoted the popularity of blockchain. Similarly, the use of game development experience and game design concept to develop a game

What kind of blockchain technology is popular recently? Blockchain technology is considered to be the brightest star in financial technology, and it may continue to develop in the future. It has many characteristics, including data distribution, data trust and collective consensus mechanism, and most importantly, openness, transparency, anonymity and privacy, According to the data in the blockchain, we can get some basic information of contemporary society
blockchain technology is such a safe and scientific database. It can be simply understood as an authoritative database, in which the basic content is true, verified and audited by others. In terms of financial technology, it is very easy to find some desired data, which is very good for business people
7. The application of blockchain technology in life has just started, but the changes it brings are very huge. This kind of change comes from all aspects, and will have an important impact on our ordinary people's lives
"now the college entrance examination is a lifetime, but if we use the form of blockchain, we can record all the learning records and extracurricular activities of a child from the age of six to the college entrance examination. So the examiners of the college entrance examination don't need to pass an exam or an interview to decide the selection of talents. They can decide what kind of talents they want through all their records. "
about the application of blockchain technology, Qin Yi, partner of Deloitte global financial services, said when introcing it to Jinping media
as for blockchain, more explanations in China still stay at the conceptual level, and there is no really large-scale popular application in China, so we have to say that blockchain still keeps a certain distance from the public. In this interview, I believe it can help you have a deeper understanding of blockchain
blockchain is disintermediation
blockchain, and many explanations are decentralization. Different from the general explanation. "It's not decentralization, it's disintermediation," says Qin
because data is distributed in a distributed way, there is a strong security mechanism in it. Qin Yi said: "because no matter which server is serving, the entire data storage is not easy to detect. But most importantly, because of the reliability of the data, we don't need an intermediary to prove who you are, but rely on a record that we can trust each other to promote any transaction in our life
in her opinion, blockchain is actually a database, but when storing data, it has its own characteristics, such as security, integrity, authenticity, non tamperability, etc
for this technology, Qin Yi concluded: such technology will bring earth shaking changes to life
how to embody the commercial value
compared with foreign blockchain technology, domestic blockchain technology is still in a stage of popularization and cognition. What kind of business value will the future blockchain bring us? Looking at the progress abroad, maybe you can see some possibilities
"two weeks ago (on April 20), Bank of Ireland and Deloitte jointly issued a statement. Three months ago, Ireland's International Investment Banking Department asked Deloitte to help design and track the investment behavior of its clients. Strengthen the understanding of customers. In order to meet the regulatory requirements of Europe, they have successfully completed the validation model through the efforts of the past three months. "
a Deloitte executive also said that if this technology can be applied, it will greatly rece the transaction costs of the instry
Deloitte also published a report in 2016, saying that 2016 will be the first year for blockchain to move from laboratory to real life. Bubi (Beijing) Network Technology Co., Ltd. (hereinafter referred to as Bubi) is a leading blockchain technology service provider in China. Since its establishment, Bubi has been focusing on the R & D and innovation of blockchain technology and procts. It has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as mathematically proven distributed consensus technology, distributed consensus technology, and so on Fast large-scale account book access technology, multi chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. We have developed our own blockchain basic service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely
with the in-depth development of many companies, the effect of blockchain technology on the life of ordinary people is becoming more and more obvious.
