1. What can the go language do

1. Server programming: If you used C or C++ to do those things in the past, it is very suitable to use Go to do them, such as processing logs , data packaging, virtual machine processing, file system, etc.

2. Distributed systems, database agents, middleware: such as Etcd.

3. Network programming: This area is currently the most widely used, including Web applications, API applications, download applications, and Go’s built-in net/http package basically implements all the network functions we usually use. .

4. Development of cloud platforms: Currently, many foreign cloud platforms are developed using Go. The well-known Qiniu Cloud, Huawei Cloud, etc. have products developed using Go and are open source.

5. Blockchain: There is currently a saying that technical practitioners call Go language the development language of the blockchain industry. If you study blockchain technology, you will find that many blockchain systems and applications are developed using Go. For example, ehtereum is currently the most well-known public chain, and fabric is currently the most well-known. Alliance chains, both have go language versions, and go-ehtereum is also the officially recommended version of Ethereum.

Many later projects were re-implemented natively using the Go language. This process was simpler than other languages, which also contributed to the emergence of a large number of native development projects using the Go language. .

2. What do you think about the future prospects of blockchain

Development trends:
1. Development trends of core key technologies
From the area Judging from the current technology and applications of blockchain, its core is existing computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. As the application of blockchain continues to deepen, new and higher requirements will continue to be put forward for these core technologies. Research results in consensus mechanisms, security algorithms, privacy protection and other related technical fields will play an important role in the leap-forward development of blockchain technology and applications, and continued innovation and breakthroughs in these technologies will be critical.
(1) Development Trend of Consensus Mechanism
In terms of public chains, currently commonly used consensus mechanisms have the shortcomings of low performance and high energy consumption. "Side chain" technology can only solve some problems under certain specific conditions. Most of the current mainstream consensus mechanisms in alliance chains are based on PBFT and its variants. Although adding permission control can greatly improve performance, it also sacrifices part of the efficiency, constraints, fault tolerance and other aspects of the consensus. It is foreseeable that universal and better consensus algorithms and decisions for some typical scenarios will continue to appear.
(2) Development Trend of Security Algorithms
Security is particularly important for systems represented by financial-grade application systems. On the one hand, the large currently usedMost traditional security algorithms have potential "backdoor" risks and need to be gradually replaced with more secure state-secret algorithms, and the strength of the algorithms also needs to be continuously upgraded; on the other hand, it is also necessary to prevent some new technologies, such as quantum computing, from affecting Impact and even subversion of traditional security algorithms.
(3) Development Trend of Privacy Protection
At present, the privacy protection links related to blockchain are still relatively weak. Especially for sensitive data, privacy protection and compliance supervision need to be balanced. Information privacy protection technologies, such as zero-knowledge proof, homomorphic encryption, etc., are also an important direction for subsequent development.
The above core technologies are partial to underlying computer technologies, and their development requires considerable investment in personnel and time, and will be a continuous and progressive process. The research results and collaboration between relevant enterprises, scientific research institutions, universities, etc. in these fields are very important to the development of blockchain technology.
2. Development trend of general development platforms
Currently, many IT companies, consulting companies, communities and technology alliances have invested in blockchain application research and development, established general development platforms and continuously improved them, which has a great impact on the entire The application of blockchain technology has a great promotion effect.
Similar to cloud computing's IaaS (Infrastructure as a Service) and PaaS (Platform as a Service), it is a general blockchain consisting of an infrastructure support layer, a blockchain core component service layer, and a corresponding development test suite. The development platform can completely provide one-stop, low-cost technical services for building and deploying blockchain applications. At present, some such platforms have emerged. With the rapid development of blockchain applications and the heavy investment of relevant participants, their service coverage, R&D convenience, operation and maintenance intelligence, as well as high stability, large capacity, low cost Costs are all foreseeable development directions.

3. What are the application scenarios of cloud computing

Cloud computing is closely related to us and is used in life, games, videos, security, Internet of Things, 5G, blockchain and other scenarios.
Scenario 1: Games: LOL, csgo, Peace Elite, etc. are based on cloud computing platforms and dynamic expansion remains stable.
Scenario 2: Blockchain: Blockchain technology is in the process of development in China. At present, the most important thing is the security of the blockchain website architecture, which is also the core of cloud computing.
Scenario 3: Smart Home: There are massive amounts of data behind the smart homes of major manufacturers such as Huawei and Xiaomi, which need to be processed and analyzed to give users the best experience and the experience they need most. Behind the support is distributed storage. and big data analysis.
Scenario 4: Online live broadcast: Behind various live broadcasts and live broadcasts such as Bilibili Live, Douyin Live, Taobao Live, etc., thousands to ten thousand servers support the operation, batch maintenance and upgrades, traffic control, etc. Another goal of cloud computing is automation.
Scenario 5: Network security: Previously, our security was achieved through hardware firewalls and open source firewalls. In large traffic and high concurrency scenarios, we need traffic diversion and usage behavior detection to ultimately ensure security.
Scenario 6: The advent of 5G: In the past, Internet websites in the 4G era were almost similar to traditional PC websites. With the increase in speed in the 5G era, websites have to cope with large traffic access, various caches, message queues, and CDN architecture. used to solve such problems.
Scenario 7: Cloud mobile phone, cloud computer: Starting from the popular cloud host in 2020, cloud computer fundamentally solves the problem of inconsistent power performance of everyone’s mobile phone. All you need is a monitor with Internet access to connect and use a cloud phone/cloud computer. The core technology behind the cloud phone/cloud computer is cloud computing.
Scenario 8: Internet of Things Architecture: The Internet of Things (IOT) allows everything to be connected through the network, such as smart homes and driverless cars. The platforms behind these Internet of Things architectures are cloud computing platforms and cloud servers.

4. Is the enterprise-level blockchain cloud service platform BaaS?

BaaS is the same as IaaS, PaaS and other concepts, and tends to be within the scope of public cloud, while enterprise services Consider more customized needs. Based on many years of practical experience from enterprise users, ChainNova is building solutions from both public cloud and hybrid cloud (i.e., enterprise cloud services). Currently, well-known domestic and foreign cloud service providers such as AWS are preparing to launch systematic service solutions, hoping to bring more flexible, complete, and powerful technical capabilities to customers. The purpose of establishing such a blockchain technology capability platform and the smart chain ChainNova is of course to better help customers solve problems. In the financial field, ChainNova is cooperating with industry leaders such as IBM to jointly create end-to-end industry solutions with the help of both parties' rich experience in financial industry scenarios.

5. Let’s talk about BasS-Blockchain as a Service

1. What is Bass

2. The development trends and challenges of the Bass industry

1. What is Bass?

1.1 Definition: Bass Blockchain as service. That is, it provides one-stop blockchain services to developers and entrepreneurs based on their needs.

BasS is one of the ways to combine cloud computing and blockchain technology. One is that the blockchain is on the cloud, and the other is that the blockchain is in the cloud. That is, the blockchain Bass service. Compared with the first method, the second method is simpler and has lower development costs for developers.

Tencent Cloud and Ant Blockchain both provide BasS services directly. They are said to be cloud service providers themselves, so when combined with cloud services, the cost is low and implementation is easy. For users, of course, the threshold for use is lower, and they can just call the interface directly.

However, small and medium-sized platforms like ours generally provide the firstIn this way, in view of our server procurement costs and the security and privacy considerations of customer information data, during the implementation phase, we generally ask customer service to provide servers (either cloud services or self-built hardware services), and we have dedicated technical personnel to The chain is set up on the client's server. Provide key management solutions according to user needs, and provide users with APIs to interact with the blockchain. (In addition to standardized APIs, we will help users define some API fields according to user needs, and provide users with front-end applications and areas. Upgrade suggestions for blockchain integration), and build underlying visualization (blockchain browser) and management and control systems (authority management system, visual management system), big data processing system, visual large-screen solutions, etc. for users according to their needs.

Note: IasS (Infrastructure as a Service), that is, Infrastructure as a Service. Refers to a service model that provides IT infrastructure as a service through the network and charges based on the actual usage or occupation of resources by users

PasS (platform as a service) PaaS The company provides a variety of solutions for developing and distributing applications online, such as virtual servers and operating systems. This saves you money on hardware and makes collaboration between dispersed studios easier.

Is Alibaba Cloud iaas or paas?

Alibaba Cloud should belong to IaaS, while Sina Cloud, Network Cloud and Network Open Cloud Platform belong to PaaS.

IaaS actually provides a server, and users can install and configure various software environments on the server by themselves. Various functions can be implemented flexibly.

PaaS is currently mainly a WEB environment application, usually supporting PHP, Java, Python and GO languages. It must be developed within the framework of the cloud computing service provider.

IaaS requires you to build your own program running environment. The advantage is flexibility, but the disadvantage is that you need to configure it yourself

PaaS does not require you to configure the environment yourself. The disadvantage is that you must use a designated development language. Follow the development specifications of the platform.

1.2 Technical characteristics of Bass mode

1. Technical framework: relatively stable performance, high versatility, reasonable layered decoupling elements

2. Product system, with one-stop commercialization capabilities, providing functional retreat and mis-scenario adaptation capabilities

3. Ecological construction, in blockchain security, blockchain tools, and blockchain industry Adaptation field itinerary partner matrix to accelerate commercialization

4. Application practicePractice, with core capabilities such as measurable value, versatility, templates, and flexible adaptation for business development

1.3 The difference between BaaS and BTaaS.

BTaaS, that is, Blockchain Technology as a Service, which means blockchain technology service in Chinese, refers to using blockchain technology to build a new blockchain and combining it with real business needs to develop applications on the chain or combine it with applications.

From this, the service we provide is actually closer to BTaaS.

1.4 Relevant data predicts that the blockchain BasS market will exceed US$30 billion in 2024.

I don’t know how to predict it! In fact, I should look for information myself and think carefully about what this market is like!

2.Bass development trends and challenges

2.1 Trends

The prospect is relatively broad and the development is rapid. Since the concept of blockchain as a service was proposed, , many giants in the world have entered the game. With the development of blockchain technology, the Bass market will usher in a large-scale explosion.

Polyoligopoly and vertical field BaaS coexist and develop. Not only giants, but also blockchain manufacturers in multiple vertical fields have entered BasS. For example, Zhigui, which specializes in copyright, has also launched its own BasS platform. .

The technical differences are small and the products and services are the main features

Most of the underlying blockchain platforms use the Hyperledger or draw on the Ethereum framework. The technical differences are actually Relatively small, the future competitiveness lies more in product ideas and service capabilities.

The BasS platform still has some way to go before it is truly decentralized.

True decentralization actually still depends on the public chain. In addition to coins, are there other incentives for the operation of the public chain? Need to think

But I have always believed that in the future there will be a high-performance public chain connecting the entire world, and we can build our own chain and selectively link the required data to this public chain. , achieve openness and credibility!

2.2 Challenges

The limitations of the blockchain technology itself: Limited by the performance of the blockchain technology itself, TPS cannot be achieved, and many seemingly good It is difficult to implement applications, such as transactions and settlements in the financial field.

The development of other technologies: In addition to transactions, blockchain technology itself is only a trusted storage method. It can only guarantee the authenticity of the chain. Every interaction with the real worldBoth parties must have credit endorsements. Many of its application scenarios, such as traceability, actually rely on the development and application of other technologies such as the Internet of Things and digital identity, and require institutional and rule guarantees.

People’s perception: Blockchain technology is still in a very early stage of development. Most people don’t understand it and are not even willing to accept it, so there are not many real applications. .

6. What earth-shaking changes will blockchain bring and how will it change life?

In addition to being used in the financial industry, blockchain is also used in other fields. In fields such as law, retail, Internet of Things, and medical care, blockchain can solve trust problems, no longer rely on third parties to establish credit information sharing, and improve the operating efficiency and overall level of the entire industry. Extremely high productivity will connect all people and machines in this society into a global network, and mankind will accelerate towards an era where goods and services are almost free. Perhaps by the second half of the 21st century, capitalism will decline and areas The decentralized collaborative sharing model of the blockchain will replace it and become the new model that dominates economic life.

Blockchain is the best technical means for this new collaborative sharing model. The infrastructure of blockchain allocates global resources in a decentralized manner, making blockchain an ideal technical framework for promoting social and economic development. The operational logic of blockchain lies in its ability to optimize peer-to-peer resources, global collaboration, and the sensitivity that fosters and encourages the creation of social capital in society. Establishing various platforms for blockchain can encourage a collaborative culture to the greatest extent, which complements the original shared model and will make it the decisive economic model of the 21st century.

7. What role does blockchain application play in network security?

Blockchain technology can help us improve the security of protection mechanisms such as encryption and authentication, which is important for the security of the Internet of Things And this is definitely good news for the DDoS defense community!

Blockchain has the potential to become an important solution for the security community, also for finance, energy and manufacturing. For now, verifying Bitcoin transactions is one of its primary uses, but the technology could also be extended to applications such as smart grid systems and content delivery networks.

How to apply blockchain to network security?

Whether it is protecting data integrity or using digital identification technology to protect IoT devices from DDoS attacks, blockchain Chain technology can play a key role, at least now it has shown this ability.

IoT security and DDoS defense community

A certain blockchain startup claims that their decentralized “accounting” system can help users resist DDoS attacks with traffic exceeding 100Gbps. Interestingly, the company stated that this decentralized system allows users to rent out their own additional bandwidth and "submit" bandwidth access rights to blockchain distributed nodes. When the website suffers a DDoS attackWebsites can utilize this rented bandwidth to mitigate DDoS attacks.

Improving confidentiality and data integrity

Although the original design of the blockchain did not take into account specific access control, some blockchain technology implementations have now solved the problem of data Confidentiality and access control issues. In this era where any data may be tampered with, this is obviously a serious problem, but complete data encryption ensures that the data will not be accessed or tampered with by others through man-in-the-middle attacks and other forms during transmission.

The entire IoT industry requires data integrity assurance. For example, IBM allows users to manage IoT data in a private blockchain network in its Watson IoT platform, and this blockchain network has been integrated into their Big Blue cloud service. In addition, Ericsson's blockchain data integrity service provides comprehensive auditing, compliance and trustworthy data services to allow developers to leverage the Predix PaaS platform for technical implementation.

One of the best applications is transforming our public sector and creating citizen-centric infrastructure. This will enable citizens to have their own identity and every transaction can be verified. We can use smart contracts and signed assertions to formulate elements of public services, such as benefits and benefits.

Internet of Things & Smart Devices

Now the attention of the entire IT community has begun to shift to the Internet of Things & Smart Devices, and security is definitely one of the primary considerations. Although the Internet of Things can improve our work and productivity, it also means that we need to face more security risks. Many companies are therefore looking to apply blockchain to secure IoT and Industrial IoT (IIoT) devices because blockchain technology can enhance identity verification, improve data traceability and liquidity, and assist in record management.

Blockchain technology can help track hacking attacks, according to Kaspersky Lab anti-virus expert Alexey Malanov, who added:

“Network intruders often remove Permission logs to hide traces of unauthorized access to devices. But if the logs are distributed across multiple devices (for example, through blockchain technology), the risk can be reduced as much as possible."

Digital Economic Development Fund Chairman German Klimenko said: "Currently, the Department of Defense is vigorously promoting IT development and research efforts, which is a good thing for the industry."

NATO and the Pentagon are also Research “defensive” applications of blockchain. This technology is actively used to protect systems from cyberattacks. NATO will use blockchain to protect financial information, supply and logistics chains, while the Pentagon is developing a hack-proof data transmission system.

In general, blockchain technology is not omnipotent, at least not yet. Whether it is from the perspective of technical integrity or systemConsidering the system implementation, current blockchain technology cannot ensure 100% device security. Note: The above content comes from the Internet.

8. When was Tencent’s blockchain team established?

A vigorous “blockchain movement” swept across like a wave, embracing everyone around it. one person. The debate surrounding blockchain has never stopped from last year to this year. Is blockchain the "spring of mankind" and "the antidote to the global economic collapse" as its advocate Chen Weixing said, or is it as its skeptic Zhu Xiaohu What he said is that "blockchain is a fake trend, and there is nothing left except currency speculation."

We believe that this industry needs standards, otherwise everyone will talk about blockchain for a long time, and the concepts they talk about are different. Some companies even claim to do blockchain by themselves, but they just use Change the database. With the authoritative standard of trusted blockchain, companies that are obviously trying to sell their products can be screened out, and companies that truly engage in blockchain technology can get endorsements.

CE: Faced with the problem of scarcity of talents in the blockchain field, how does Tencent solve it?

Cai Yige: Our technical talents are basically converted from within Tencent. The blockchain industry is very new, and few people have done blockchain. Just like the arrival of mobile networks back then, it was difficult to recruit Android and IOS developers. We all trained ourselves.
