ⅠHave blockchain and decentralized clouds made much progress

About the potential benefits of hosting cloud computing on a centralized or decentralized network and blockchain There is some debate as to whether some correlation is possible in this regard. The answer seems to be yes—under certain circumstances.

Avivah Litan, vice president and analyst at Gartner, said that blockchain supports decentralized cloud computing, which may lead to some new computing methods and Web 3.0 hype. "In that sense, it's disruptive to people who are concentrated," she said. "This is not going to disrupt the industry overnight; I don't think it's going to happen that fast."

Litan said decentralized cloud computing could be an alternative, perhaps even for some non- Blockchain applications make sense. There may still be reluctance within organizations to quickly move workloads in this direction, she said. However, for some applications, such a move may be a way to save money.

Entering this space means embracing a nebulous, almost amorphous form of cloud computing. Blockchain’s decentralized architecture often means it will never operate in just one environment, Litan said. “If you look at a blockchain with 10,000 nodes, you can run your nodes anywhere you want.” For Bitcoin or Ethereum miners who are mining, they can run them locally or Set up their nodes on any cloud of their choice. In that sense, it's not centrally controlled by any one player, Litan said.

It still seems to be early days in terms of how much of the data space and cloud is tied to Web 3.0 activity. For example, she said, cryptocurrency transactions may not represent large amounts of data, but once an NFT commerce involves large objects, it may require distributed storage. Options for such storage include IPFS (InterPlanetary File System), Litan said, which is a peer-to-peer network data storage in a distributed system, and value-added systems like Arweave, which makes IPFS more reliable, secure, and persistent.

There are still functional issues that may prevent developers or organizations from taking advantage of distributed systems. “The reason you want to use decentralized computing is if you’re setting up your own nodes, or you’re writing applications that require computing power,” Litan said.

Some of the benefits of moving to a decentralized cloud, she said, include that it can be a way to cut costs rather than listening to a centralized entity that can raise rates, own user data and lock it in place. Fang’s whim. “Moving workloads from one cloud provider to another is very difficult,” Litan said. "thisCertainly a nice innovation. ” However, she said that this kind of innovation has been discussed for years, but the progress is uncertain.

Basically, the value of the decentralized cloud in its current form comes down to the user’s situation and needs. “If You are setting up a mining node and need some cloud computing power, why should you pay AWS? " asked Litan. In this case, she said, a decentralized cloud would likely be cheaper to run, attracting miners who want cheap computing to make a profit.

Currently, when many developers write applications, they look for the most accessible cloud service, Litan said, and then end up deploying on the main blockchain where they have no control over where Ethereum or Bitcoin runs. "It's like saying , 'Where Does the Internet Run?' '"

Blockchain and decentralized cloud have the potential to gain more momentum in the future, but for now their impact on cloud computing as a whole is still quite niche. "As people start writing compute-intensive workloads and looking to reduce costs, that may become more important," Litan said. Decentralized cloud computing may also be useful for organizations running non-blockchain applications, she said. "Then they control their own environment, where they deploy it, and How much does it cost. They control the entire stack. ”

Ⅱ The future of blockchain is a major trend

Blockchain uses P2P technology, cryptography and consensus algorithms and other technologies, and has the characteristics of data non-tampering, collective system maintenance and information disclosure. Transparency and other characteristics. Blockchain provides a mechanism for information and value transfer and exchange in an untrustworthy environment, and is the cornerstone of building the future value Internet.

Trend 1: Acceleration of application in the blockchain industry Promote the penetration and spread from digital currency to non-financial fields

As a universal technology, blockchain technology is accelerating its penetration from digital currency to other fields and integrating with innovations in all walks of life. We believe that in the future The application of blockchain will be promoted by two camps. On the one hand, the IT camp starts from information sharing and builds credit at low cost as the core, gradually covering areas such as digital assets. On the other hand, the cryptocurrency camp starts from currency and gradually moves towards Advances in asset-side management and certificate depository areas, and spreads to credit reporting and general information sharing applications.

Trend 2: Enterprise applications are the main battlefield of blockchain, and alliance chains/private chains will become mainstream Direction

At present, the practical applications of enterprises are concentrated in the field of digital currency, which belongs to the virtual economy. We believe that in the future, blockchain applications will move from virtual to real, and more traditional enterprises will use blockchain technology to reduce costs. Cost reduction, improving collaboration efficiency, and stimulating real economic growth will be the main battlefield for blockchain applications in the future.

Different from public chains, in enterprise-level applications, everyone pays more attention to the management and control, regulatory compliance, performance, security and other factors of blockchain. Therefore, we believe that strong management blockchain deployment models such as alliance chains and private chains are more suitable for enterprises to use in application implementation, and are the mainstream technology direction for enterprise-level applications.

Trend 3: Applications have spawned diversified technical solutions, and blockchain performance will continue to be optimized

In the future, blockchain applications will develop from single to multiple directions. Different applications such as billing, payment, insurance, and supply chain will be highly differentiated in multiple dimensions such as real-time, high concurrency, latency, and throughput. This will lead to a diverse range of technological solutions. We believe that blockchain technology is far from finalized and will continue to evolve in the future. There is room for efficiency improvement in technical aspects such as consensus algorithms, service sharding, processing methods, and organizational forms.

Trend 4: Blockchain and cloud computing are increasingly integrated, and BaaS is expected to become a public trust infrastructure

Cloud computing is the general trend. We believe that the combination of blockchain and cloud is also an inevitable trend. There are two models for the combination of blockchain and cloud, one is blockchain on the cloud, and the other is blockchain in the cloud. The latter one, namely BaaS, Blockchain-as-a-Service, refers to the cloud service provider directly providing blockchain as a service to users. In the future, cloud service companies will increasingly integrate blockchain technology into the cloud computing ecological environment. By providing BaaS functions, they can effectively reduce the deployment cost of enterprise application blockchain and lower the initial threshold for innovation and entrepreneurship.

Trend 5: Blockchain security issues are becoming increasingly prominent, and security protection requires overall technical and management considerations

From a mathematical perspective, the blockchain system is almost perfect. It has the advantages of openness and transparency, difficulty in tampering, reliable encryption, and resistance to DDoS attacks. However, from an engineering perspective, its security is still restricted by infrastructure, system design, operation management, privacy protection, and technology update iterations. In the future, we need to consider the overall situation in terms of technology and management, and strengthen basic research and overall protection to ensure application security.

Trend 6: The cross-chain demand for blockchain is increasing, and the importance of interconnection is highlighted

With the deepening of blockchain applications, payment and settlement, logistics traceability, medical records Enterprises or industries in areas such as identity verification and identity verification will establish their own blockchain systems. We believe that cross-chain collaboration and interoperability among these numerous blockchain systems is an inevitable trend in the future. It can be said that cross-chain technology is the key to blockchain realizing the Internet of Value, and the interconnection of blockchains will become an increasingly important issue.

Trend Seven: Blockchain competition is becoming increasingly fierce, and patent competition has become an important area of ​​competition

As the number of participating entities increases, the competition in the blockchain will become increasingly fierce, and competition is all-round , including technology, models, patents and other dimensions. We believe that in the future, companies will strengthen their layout in blockchain patents. Since 2014, the number of blockchain patent applications has exploded. Blockchain patents are mainly distributed in the United States in North America, the United Kingdom in Europe, and China and South Korea in Asia. This pattern will be maintained in the future. The patent gap between China and the United States is narrowing, and China’s number of applications in 2016 has surpassed that of the United States. It is foreseeable that the competition for blockchain patents will become increasingly fierce in the future.

Trend 8: Blockchain investment continues to be popular, and the cumulative risks of the token crowdfunding model deserve attention

Blockchain has become a hot spot pursued by the capital market. Future investment will continue the rising trend from 2014 to 2016. Different from financing models in other technology fields, a model called "token crowdfunding" has emerged in the blockchain field, namely Initial Coin Offering (ICO), which is a type of crowdfunding for startups to issue tokens and raise funds. Way. As the transaction volume of token crowdfunding increases, risks such as lack of review, huge value fluctuations, and being on the edge of regulation for many projects will increase, which deserves attention. This afternoon, a group of friends chatted with me privately and asked about the so-called golden chain, which needs to rely on the model of 1 pass 2, 2 pass 4, 4 pass 16 to obtain income. This is an obvious pyramid scheme to attract people, but there are still many people who just Friends who have entered the currency circle and have just learned about blockchain will be deceived. I hope they can understand the essence and be responsible for their own funds!

Trend 9: Blockchain technology and supervision are in conflict, but the contradiction is expected to be further reconciled

The decentralization, disintermediation and anonymity of blockchain are in line with its tradition The corporate management and government regulatory systems are not coordinated. But we should also see the opportunities that blockchain brings to supervision. We believe that in the future, enterprises will actively cater to regulatory needs and proactively build in regulatory requirements in technical solutions and model designs. They will not only achieve compliant operations, but also significantly save the cost of regulatory compliance. We also believe that in the future, regulatory authorities around the world will also embrace blockchain, a new regulatory technology, and use new technology to improve government regulatory efficiency.

Trend 10: Trustworthiness is the core requirement of blockchain, and the importance of standards and specifications is becoming increasingly prominent

In the future value delivery network based on blockchain, We will use algorithms and software entirely to build a foundation of trust. But we believe that this is far from enough. Standards are also needed to add credibility to the blockchain. future, the standard of blockchain will start from the user's perspective and be business-oriented. It will standardize the technology and governance of blockchain from the dimensions of smart contracts, consensus mechanisms, private key security, and authority management, and enhance the credibility of blockchain. The degree of trust adds weight to the trust of the blockchain.

Summary

The above are the ten major trends summarized. To summarize, there are four points: First, blockchain is the foundation of the value network and has gradually become an indispensable part of the future Internet. Second, as application scenarios become increasingly abundant, applications will drive the continuous improvement of blockchain technology, and the integration of blockchain and cloud will become increasingly closer. Third, although the blockchain is mathematically complete, there are also security issues. In the future, security needs to be strengthened from the engineering and management levels, and standards are also needed to improve credibility. Fourth, blockchain technology will gradually adapt to regulatory policy requirements in the future and gradually become an important tool for regulatory technology.

Ⅲ What is the relationship between blockchain and cloud computing and cloud storage? Is blockchain cloud computing or cloud storage?

Cloud computing storage can be used as the lower layer of blockchain. Cloud computing or cloud storage is infrastructure, which can be understood as a new generation of computers (or hard drives), while blockchain can be seen as a business-oriented accounting system (or a trusted database).

IV Which is more important, blockchain or cloud computing, in the digital economy?

Blockchain is more important in the digital economy, because in the digital economy, blockchain is where data is stored and analyzed. , is the root of decision-making, so it is more important.

IV When blockchain meets cloud computing, what will the world become?

Blockchain meets cloud computing, just like a fish meets water, the world will become By opening a new door, human civilization will advance further. Clouds are like network points, and clouds are like network nodes, which eventually converge into the sky. Chains are like connections that cannot be broken. They can tightly string together clouds. The combination of the two forms a huge data sharing. platform.

1. The principle of cloud computing is fractional computing, which decomposes huge data calculation processing programs into countless small programs, and then returns these data processing results to the user. A huge computing project is directly handed over to Cloud computing saves users time and energy; blockchain is a new application model such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. It is also a docking and storage node, and its functions are similar to those of cloud computing. Complementing each other, the birth of these two major technologies in the information age will definitely shock the world.

Ⅵ Understand the relationship between blockchain and big data, cloud computing, and Bitcoin

Blockchain is an untamperable, full-history Database storage technology, a huge block data collection contains the entire history of each transaction. With the rapid development of blockchain applications, the data scale willIncreasingly, different business scenarios have enabled the data integration of blockchain to further expand the scale and richness of data. However, what the blockchain provides is the integrity of the ledger, and the ability of data statistical analysis is relatively weak. Big data has massive data storage technology and flexible and efficient analysis technology, which will greatly enhance the value and use space of blockchain data.
Digital currency is a form of expression represented by blockchain 1.0, mainly Bitcoin; as a virtual currency system, the total amount of Bitcoin is limited by the network consensus agreement, and no individual or institution can Changes and modifications to the supply and transaction records, so after the Bitcoin network has been successfully running for many years, the blockchain, as the underlying technology that supports the operation of Bitcoin, is essentially an extremely clever distributed shared ledger and peer-to-peer value transmission technology. It will have a very large potential impact on finance and even all walks of life.
Blockchain and cloud computing, the research, development, and testing of blockchain technology involve multiple systems. Time and capital costs will hinder the breakthrough of blockchain technology. Software development based on blockchain technology, It is still a high-barrier job. Cloud computing services have the characteristics of elastic resource scalability, rapid adjustment, low cost and high reliability, which can help small and medium-sized enterprises to develop and deploy blockchain quickly and at low cost. The integration of the two technologies will accelerate the development of blockchain technology. The blockchain technology is mature and promotes the rapid expansion of blockchain into the financial industry.

Ⅶ Do artificial intelligence, big data, cloud computing, Internet of Things, and blockchain exist independently?

They are not independent entities. Artificial intelligence, big data, cloud computing, the Internet of Things and blockchain are all important development directions in the field of modern information technology, and they are interrelated and mutually reinforcing. Big data provides rich data resources and analysis methods for artificial intelligence, cloud computing and the Internet of Things. The combination of the Internet of Things with cloud computing, artificial intelligence and other technologies can also bring more application scenarios to the industry. Blockchain can provide a more secure and reliable data exchange and management method for the Internet of Things, big data and other fields. These technologies are interdependent and mutually supportive, and their development will have a profound impact on the future development of the entire information technology field.

ⅧLinux learning materials: What is the relationship between blockchain and cloud computing

After years of development, cloud computing has become a very mature technology. Experts define cloud computing this way: Cloud computing is a pay-per-use model that provides available, convenient, on-demand network access to a configurable shared pool of computing resources (resources include network , servers, storage, applications, services), these resources can be provisioned quickly with minimal management effort or minimal interaction with the service provider.
The concept of blockchain is relatively simple. It is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Its essence can be understood as distributed ledgers and smart contracts. If it were simpler, the blockchain is equivalent to a protocol like HTTP, which is used for value exchange and value transfer.
After understanding the definitions of the two, you will find that from a definition point of view, there is no connection between the two. But in fact, blockchain, as a resource with on-demand attack requirements, can be understood as part of cloud computing. So in general, although the two are very different, they can be integrated with each other. I believe that better technologies will be born.

Ⅸ How are blockchain and cloud computing related?

Blockchain is an intelligent peer-to-peer network that identifies, disseminates and records information in distributed databases, also known as value internet.

Cloud computing is an Internet-based computing method in which shared software and hardware resources and information can be provided to various computer terminals and other devices on demand.
It can be seen that blockchain is more inclined to the identification, dissemination and recording of information, while the latter is only a calculation method based on shared hardware or information.
In the future, blockchain and cloud computing can be combined.

Ⅹ Cloud Computing and Blockchain

Before understanding the specific relationship between cloud computing and blockchain, we need to Do you know what blockchain is?

We might as well first use an example to gradually understand the blockchain. It is said that in a village lacking trust, the old village chief invented a new accounting method in order to prevent villagers from denying each other when borrowing money from each other: if Zhang San borrowed 100 yuan from Li Si, the village loudspeaker would Announce the news to the whole village. The villagers each have an account book in their hands. At this time, they will separately write down "Zhang San borrowed 100 yuan from Li Si at such and such a time." It would be useless if Zhang San wanted to deny it when the time came to repay the loan, because this record was written in the account books of other people in the village. This is the prototype of blockchain.

With the above cases, it is not difficult to understand the meaning of blockchain when we describe it. Blockchain refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. Take accounting as an example. There is no central ledger in the blockchain. Everyone has the opportunity to participate in accounting. Everyone is the center, and everyone in the system has a ledger. With the above foreshadowing, let’s get down to business.

With the widespread application of cloud services, the impact of cloud service provider equipment failures is increasing. Almost all centralized cloud service providers have experienced failures or even data loss. So, is it possible to cure this problem? A simple idea is "don't put all your eggs in one basket". A more professional one is "distributed cloud computing + blockchain".

Before the birth of blockchain technology, many cloud computing manufacturers used distributed cloud computing to solve the shortcomings of centralized cloud computing. Distributed cloud computing studies how to solve a problem that requires a lot of computing powerThe problem is divided into many small parts, and then these small parts are assigned to many computers for processing, and finally the computer results are combined to obtain the final result.

"Cloud computing + blockchain" is called BaaS, which means Blockchain Technology as a service, which translates to Blockchain as a Service. At present, many Internet giants have announced the launch of BaaS business. IBM announced the launch of a blockchain service platform in February 2016, where developers can access fully integrated development and operation tools for creating, deploying, running and monitoring blockchain applications on the IBM cloud. As a pioneer in the successful implementation of "distributed cloud computing and blockchain" in China, Xunlei has now achieved the combination of distributed cloud computing and blockchain technology.
