『一』 Amber Group: Is social networking the next trend in blockchain applications?
Blockchain technology is the next generation underlying value network that is constantly being recognized by more people. , along with in-depth discussions on its integration with various industries, it has brought many new inspirations and ideas. Research from Amber Group, the world's leading crypto-financial intelligence service provider, shows that blockchain technology may bring new development directions to the social field.
Current Situation: The Clear Future of Social Applications
As we all know, given the centralized development of most social application platforms and the continuous emergence of new social applications As the news emerged, corresponding problems also emerged: a large number of fake news put forward higher requirements for review; the proliferation of low-quality advertisements determined by the profit model; the potential leakage of personal privacy data, etc.
The emergence of the above problems is obviously contrary to the development trend of social applications. Amber Group research believes that the future path of social is clear: decentralization with value sharing as the core, data ownership as the core Privacy, and security with privacy protection at its core. This is undoubtedly consistent with the properties of blockchain technology to a certain extent. Although based on the current technological stage, blockchain cannot solve all problems in social applications, it brings very meaningful ideas.
Subversion: Web 3.0 and decentralized social networking
Amber Group data shows that the characteristics of blockchain technology such as decentralization, openness, transparency, and trustworthy databases are based on everyone being the subject. There is a natural fit in the value network. More research shows that blockchain technology can enable users to control personal data; protect personal privacy on a technical level; and truly bind sociality and value by giving users "digital identities" to build a new Internet. This is also one of the important interpretations of Web 3.0.
Various opinions believe that innovations such as DeFi (open finance) and NFT based on blockchain networks, as well as the continuous implementation of "blockchain +", will also form the next stage of Internet development, Web 3.0. Completing. In this puzzle, blockchain technology has injected fresh blood into social networking. Its distributed network can help social applications achieve decentralization. Users can gain higher autonomy, security, and even considerable benefits in decentralized social networking. economic returns.
Obstacles: Blockchain + social still needs to be explored
It is reported that in early 2021, Twitter founder Jack Dorsey published an overview of the decentralized social ecosystem, which discussed Blockchain technology builds a decentralized social ecosystem and has various feasibility in terms of system architecture, core technology, and platform design. It also mentions various challenges and risks.
Jack Dorsey tableSaid that one of the obstacles to blockchain + social is the current lack of resources - all projects currently raise funds through donations, funds or venture capital, but no sustainable business model has emerged; another obstacle is decentralization The development speed of decentralized protocols is inherently slower than that of centralized applications, because updates of decentralized applications and the participation of all users require community coordination, otherwise the network will split due to incompatibility.
Amber Group research believes that centralized social applications are indeed easier to build, iterate faster, and are easier to make profits; but decentralized, private and secure social applications are always more promising to explore. In the future, more forces may be invested in the integration of blockchain and social networking, and ultimately use blockchain technology to change the way users participate in social networking and bring more new choices to users.
『二』 What are the relationship between social networks and blockchain and what are the potential applications
The Internet has connected the world, but for children whose values have not been fully formed, , some negative energy information on the Internet can easily affect their physical and mental development, so Papa Mama Youliang appears to be very cautious about children's use of social media.
However, don’t underestimate the curiosity of babies. Sometimes Mommy’s over-protection can have the opposite effect. Xiao E thinks that we don’t need to completely deny the value of social networks because of a small number of negative cases. Using them correctly can bring more benefits to children than disadvantages:
Make more friends
The Internet breaks geographical restrictions, and babies can make friends with different people on the Internet. Racial friends, while broadening children's horizons, can also convey a positive voice to those in need.
Recognized by more people
Compared with real things and society, speech on the Internet is freer. Children can express their opinions and opinions freely without having to win over the mainstream. cultural identity.
On the other hand, children can also get high-quality assistance and answers to their questions on social networks as soon as possible.
More willing to express themselves
Social media allows children to share their works freely without so many restrictions and restrictions, especially for introverted children, the Internet is a good A way to express yourself.
Note: If a child uses social media, a responsible daddy will definitely pay close attention to the changes in the child. So, what changes are worthy of vigilance?
Suddenly stops sending messages
If your baby is usually very active on the Internet and suddenly stops updating one day, this is a warning sign that he may have encountered some trouble. Son, he may even have blocked his eyes.
Refuse to hand over your mobile phone
Although it is very necessary to give children appropriate privacy, when children are very young, the content they read still needs to be controlled by adults. If Mommy wants to check the baby’s phone, the baby will showIf you are panicking or refusing, you should be very careful.
Change usernames frequently
If the baby frequently changes usernames, in addition to coveting freshness, they may also be hiding something or avoiding certain people, Daddy. Mom should also pay attention.
『三』Does blockchain require front-end technical foundation?
Of course it requires front-end technology and support, because it is relatively front-end and molecular.
『四』 Summary of general concepts of blockchain
Although I am a front-end developer, it cannot stop me from gossiping about various hot topics. Below is a brief summary of some of the conceptual things learned.
1. Blockchain technology was born with Bitcoin, so first understand the concept of Bitcoin
2. What is Bitcoin
(1) , Digital currency based on distributed network
3. Operating principle of bit system
(1) All nodes will save complete ledgers
(2 ), the ledger maintains consistency
4. Blockchain accounting principles
Hash functions are widely used in blockchain technology
(1), Hash function hash: any information will get a short summary information after hashing
(2), hash characteristics: simplified information, identification information, hidden information, verification information
(3) Blockchain accounting will hash the bill information of the time node to form a block
(4) The Bitcoin system will record accounting once every 10 minutes, that is, every The time interval between block generation is about 10 minutes
(5) When recording the next bill, the hash value of the previous block and the current bill information will be hashed together as the original information
(6). Each block contains information about previous blocks, and these blocks are combined to form a blockchain
5. Bitcoin ownership - asymmetric encryption Application
The Bitcoin system uses the elliptic curve signature algorithm. The private key of the algorithm consists of a 32-byte random number. The public key can be calculated through the private key. The public key is processed through a sequence of hash algorithms and The encoding algorithm obtains the Bitcoin address, which can also be understood as a digest of the public key.
(1). Transfer is to transfer Bitcoin from one address to another
(2). The address private key is an asymmetric relationship. The private key passes through a series of operation (including two hashes), you can get theaddress, but the private key cannot be obtained from the address
(3) After the transfer is successful, it is broadcast to other nodes. After other nodes verify it successfully, it is forwarded to the adjacent nodes. The broadcast information contains the original information and Signature information
(4) Verification, other nodes verify whether the signature information was generated by the payer using the private key to sign the original transaction information, and only record it if it is (re-verify that there is sufficient balance)
6. How to mine Bitcoin
(1) Nodes that complete accounting can receive a certain amount of Bitcoin rewards from the system (this reward process is also the issuance process of Bitcoin , so everyone calls bookkeeping mining)
(2) Only one person can successfully bookkeeping within a period of time, so it is necessary to collect original transaction information that has not been collected and check whether there is a balance and correct Signature
(3) In order to improve the difficulty of accounting, only one person can do accounting in about ten minutes. The hash result needs to start with a number of 0s, and random number variables are introduced when hashing
(4) As more miners join, the game becomes more and more difficult, the calculation difficulty increases, the power loss increases, the domestic electricity cost is low, and China’s computing power accounts for more than half of the entire network
< br /> (5). Only the fastest decrypted block in the network will be added to the ledger, and other nodes will copy it to ensure the uniqueness of the ledger. If a node cheats and causes the entire network to fail, it will be discarded and never recorded in the general ledger. Therefore all nodes will abide by the common protocol of the Bitcoin system.
[Thinking about which fields blockchain will extend to]:
From the above concepts, it can be concluded that blockchain technology has such security, uniqueness, Decentralization.
In principle, some information leakage can be avoided, allowing the confirming party to confirm your identity without exposing your real user information.
At present, blockchain technology is mainly used in Bitcoin. I think the greater significance in the future should be in areas that require data privacy and security.
[Thinking about the bottlenecks and limitations of the current development of blockchain]:
Since each node participates in the entire ledger recording activity, it will inevitably cause waste and loss of resources. . As well as increasing the computational difficulty of each node, subsequent development and popularization require hardware improvements for each node.
『五』 "Hot Spot Observation" Using blockchain as the core technology to move towards web3.0
Recently, according to foreign media reports, Meta Platforms will provide depth for blockchain technology Compatible, integrating social systems with blockchain, cryptocurrency, etc. Web3.0Technology integration. In the next decade, blockchain technology may have a profound impact on the industry. Web3.0, the future Internet, will also be a brand new business model, and it has become a new trend.
What is the difference between Web3.0 and Web2.0?
The profit model is different: Web2.0 whether online Advertising business, SP value-added business or other charging models all require the detonation of user information on this platform; Web3.0 has a clearer and feasible profit model, and has certain fair incentives for the development team. Through Token and certain communication The license is reserved to motivate the development team, so that the development of the protocol can truly generate value and generate more practical scenarios. As the value of the token increases, corresponding returns can be obtained.
With every change, the respective positioning and relationship between users and the network are changing: users have gone from being passive recipients of content to becoming the main creators of content. and viewers, while the network has evolved from a single content-carrying platform to a service provider that can intelligently provide users with more customized help.
Web3.0 has the following characteristics: Information sources are individualized, and the sources of information gradually return to individuals instead of some authoritative institutions; communication channels are diversified, and information The dissemination of information is no longer limited to a single media and platform; customized information has become mainstream. Under the first two characteristics, information is bound to grow explosively, so how to provide customized information for users within a limited time is inevitable.
The role of blockchain in Web3.0
By many independent Nodes form a network. Even if one or two nodes are compromised by hackers, there are thousands of nodes that store safe and effective data. Even if a node is paralyzed, it can still operate normally. A decentralized network that completely removes the middleman, does not need to trust any company, does not need to trust any third party, the code is the law, just trust the mathematical and computational principles on which the blockchain is built.
The consensus mechanism of the blockchain does not require a centralized authority to make decisions. All nodes in the network that save data are driven by incentives and pooled Decisions are made together: what state the database should be in, which transactions should be accepted, and which transactions should be rejected, which determines the authenticity of the blockchain database. Blockchain brings a new economic model to Web3.0In this way, companies with centralized servers no longer have huge wealth. Blockchain gives value to the network itself and the community members connected to the network through tokens.
The intervention of blockchain, because of its decentralization and non-tamperable data characteristics, has accelerated the arrival of the Web3.0 era and further improved it. The Web3.0 era is an all-round expansion from the Internet to life.
『Lu』 Can cloud computing be understood as the front-end performance of blockchain?
1. Infrastructure providers provide virtualization services of hardware equipment to platform operators and platform developers ; 2. Platform providers provide networked platforms for platform operators; 3. Platform operators support the business of software service providers through networked platforms; 4. Software service developers develop and combine a variety of services to meet the needs of service providers Business needs; 5. Software service providers provide personalized and professional software services to users.
『撒』 What technology development is needed for blockchain
What technology development is needed for blockchain:
1. Blockchain theory: Blockchain developers need to Being familiar with the theoretical knowledge of blockchain is the most basic requirement for a blockchain developer. The content includes blockchain network architecture, decentralization and other related application technologies. Expanding technical theory is mastery of Ethereum development.
2. Smart contract: Smart contract is a string of codes that blockchain developers need to write in blockchain programming language. It is a trust mechanism developed after imagining logic according to different scenarios, aiming to eliminate the intervention of third parties. Create an efficient and high-trust blockchain network. Blockchain developers need to realize automatic execution of this string of code, and the operation effect is irreversible.
3. Cryptography: Many blockchain application scenarios have high encryption, and point-to-point encryption mode is a characteristic of cryptography. By studying cryptography, blockchain developers understand encryption concepts such as wallets, keys, and a wide range of encryption and decryption technologies
4. Distributed architecture: Blockchain developers must understand the functions of distributed architecture and networks . Decentralized network is the foundation of the blockchain architecture. The transmission of information in the blockchain network must follow a decentralized approach so that everyone can enjoy the same network rights.
『8』How should I choose between front-end and go + blockchain?
This is determined by your programming level, and the current level of domestic programmers is basically a pyramid structure , middle-level programmers account for the majority. From this perspective, it is basically impossible for most people to learn functional programming. A very important reason for choosing the Go language is that an intermediate-level programmer can write very good Go code. The main reason for this is that the Go language is very simple, has very few features, and the official class library is very rich. Most programmers can get started with development very easily. Among them, the well-known domestic open source project CHAIN33The blockchain developer platform is completely implemented in Go. There are many domestic blockchain technologies that are relatively mature, such as Weisan Cloud, etc., so I won’t go into details here.
