Yesterday morning, at the 2018 4th Blockchain Global Summit, Bitmain founder Wu Jihan talked about the eight main lines of blockchain technology development in the next ten years. Babbitt hit the spot directly. According to Wu Jihan's on-site speech, the content has been deleted.
Hello everyone. In 2008, Satoshi Nakamoto released a white paper, the birth of the blockchain, and it is the tenth year this year. I myself came into contact with the blockchain in 2007, and then put all my savings into it. Today I want to share with you some important technical issues in the next decade of blockchain.
First of all, finance is the number one application of blockchain technology, and privacy and security are the number one point of financial business. In blockchain technology, there is a contradiction between privacy and security. Well, the earliest UTXO and account models have obvious advantages in system security, because all its transaction records are recorded on the chain, whether the currency has been evaporated, or whether there are obvious loopholes in the transaction , Then all people have a very intuitive observation of the execution process of the blockchain.
So, it is more secure, even if you have a loophole, then you can find it immediately and the system can quickly find out.
Transactions on the blockchain can be observed in real time, and the privacy is not high. If you are a particularly wealthy consumer, and you don’t want you to walk into any factory or when you consume, the merchant has a very clear grasp of your personal assets, and everyone will want to block themselves. Regarding privacy requirements, we have made a lot of efforts in the past. How can we use blockchain to protect people's privacy and security in the future? The next decade of blockchain will definitely advance in this pair of contradictions.
If privacy and security are a curve, some blockchains can definitely extrapolate this curve to the farthest position, surpassing other blockchain technologies. We are also very much looking forward to some theoretical and framework breakthroughs and solutions to this contradiction.
Article 2: Technical Neutrality IssuesBlockchain is a financial network without borders, but it is a participant with borders. There are complex legislative issues that need to be resolved.
For example, if the issuer of a financial product in country A defrauds financial consumers in another country, should another country hold criminals in other countries accountable? If a blockchain in the country implements financial fraud and defrauds financial consumers in other countries, how to solve this? At the same time, cross-border capital flows are in conflict with the current systems of many countries. How can they be brought to the global financial market?
The independence of blockchain technology itself, I believe it is difficult to break. why? Because the blockchain is free. It is difficult for a regulated blockchain to maintain its independence. Therefore, I believe there will be a regulatory mechanism based on a neutral blockchain.
The most worthy reference is the Internet. Today, it is also neutral and lacks supervision. However, Internet practitioners themselves are subject to stronger and stronger supervision, and some Internet financial institutions have been incorporated into a strict legislative framework. Similarly, there will be a regulatory framework during the development of the blockchain, the process of constructing a financial order. This will also be one of the development routes for the next ten years.
Article 3: The development and performance expansion of the blockchainThe number of blockchain users is not large now, the entire network is 20 million, and the growth curve is very fast. In line with the past growth curve of the Internet, we can actually foresee that within ten years, the number of users of the entire blockchain may exceed one billion. At this user scale, the performance pressure of processing data needs to be improved by four orders of magnitude. Including sidechain and cross-chain, Lightning Network, historical technologies of compressed transactions, and software engineering technologies that comprehensively adopt hardware acceleration and parallelization.
The first is side chain technology and hurdle interaction technology. This technology can safely and quickly interconnect between the main chain and the side chain, and at the same time it can be decentralized, which is still not well solved in theory. There are two aspects to this solution. One is that we abandon the principle of decentralization and use centralization as the interconnection between the main chain and the side chain. The other is a theoretical breakthrough, but I personally do not have much confidence in the theoretical breakthrough. If it can be applied in this area in the future, a centralized solution may be better.
The second is the Lightning Network. After it was put forward, it is feasible in theory and feasible in engineering, but its overall user experience is problematic. The Lightning Network will only be used in special scenarios on machine and software, and it must be packaged as a technical tool that users cannot perceive. Any application that requires users to directly operate the Lightning Network is not economically feasible, because users will not be able to accept some strange system abnormalities in the future.
The third is to compress the history of transactions. The transaction itself is not on the chain, it just puts the result on the chain, and its own transaction compression can improve the universality, and it can also use small data to record the final result of the huge transaction history. However, this technology of compressing transaction history has security risks. Its skills are extremely difficult. If a major loophole in the encoding or decoding is discovered on a certain day, some problems may occur.
The fourth is the comprehensive use of hardware acceleration and parallelization of software engineering technology. This is particularly feasible in my opinion. If the blockchain changes some of its technical architecture in the future, its future network processing pressure will increase, and its software network architecture does not need to be greatly changed. It only needs to linearly increase the hardware server for operation and maintenance, and the expansion will be very large. easy to accomplish.
In my opinion, this is the most practical way. If the blockchain software changes some of its existing architectures in the future, as the network processing pressure increases, there is no need to make significant changes to the entire software architecture, only a few servers need to be added in parallel and linearly, and the entire capacity is expanded. Realized in theory. We should not believe the lies that are common in the market, many of which are gimmicks made to attract users. For example, it is claimed that it can achieve millions of TPS per second on its own PC or server, which sounds very ridiculous to professionals. Our actual working direction should be to modify our software architecture to be able to be on a T-level or hundreds of GB-level blocks. It can process transactions simply by adding servers in parallel. I think the software architecture is Effort is an important goal to achieve. Of course, this goal has not achieved most of the blockchain projects now. They are basically prepared for a single server. They have not done the lowest level architecture design for long-term parallelization and parallelization.
Fourth, expand the expertise of blockchain application scenariosHow does the blockchain interact with the real world? There are probably two directions. (1) Important events in the real world need to be faithfully recorded on the blockchain. For example, some companies develop blockchains for food traceability. (2) It is hoped that virtual events on the blockchain will drive changes in the physical world. For example, decentralized Airbnb. Decentralized Airbnb means that you order a room on the blockchain. When you walk in front of the room, the lock recognizes you because it rents relevant information from the blockchain, and you book After a night in the room, it will automatically open for you. This is a virtual event on the blockchain, driving changes in the physical world. Taken together, this direction is the question of how the so-called blockchain technology is implemented.
But all the landing attempts and this wave of projects, I think almost most of them will fail, and their real window of opportunity will not come in the next few years. But I believe that at the end of the next ten years, some interesting projects will begin to appear. Because such a specific application scenario, the so-called landing technology, it all involves infrastructure. It's like in the entrepreneurial activity of streaming media, it is impossible to come out of giants before the Internet bandwidth is really developed. Before the advent of mobile phone GPS applications, it was impossible to have exciting Internet entrepreneurial projects such as online car-hailing or freight forwarding. The interaction logic between the blockchain and the real world still lacks the necessary infrastructure.
The realization of two-way interconnection between such infrastructure and the corresponding blockchain real world must be driven by specific application scenarios. This is a question of whether a chicken lays an egg or an egg lays a chicken. If you interact with the real world, it may be easier if the real world is more virtual. For example, a copyright market for streaming media is now highly feasible. Because it is a kind of digital asset copyright purchase, the cost of the infrastructure it can build is relatively low.
Fifth, the security of cryptographic algorithms on the blockchainWe expect that when the second decade is about to end, quantum computers will begin to mature. In the field of blockchain, the cryptographic algorithms currently being applied, after a while, may face the pressure of upgrading at the end of the second decade. What I want to remind is that if you invest in the research of anti-quantum cryptography algorithms prematurely and put them into practice, this is an irrational behavior. It was a marketing gimmick earlier, because the pressure is not great now. And you need to select a quantum anti-leakage cryptography algorithm, preferably a general one.
Sixth, the identity of the blockchainThe first public-private key system designed by Satoshi Nakamoto, in fact, the private key is the identity on the blockchain. The technical threshold it brings is very high, that is, the private key is very common. If we transform the public and private key system into the problem of abstract identity, I believe that in the next ten years, how the blockchain will comprehensively adopt various identity authentication technologies to help everyone use the blockchain. A very important question. Why must it depend on and tightly rely on the private key to determine the identity of the blockchain user on the blockchain? For example, OP-code (sound), which BCH is about to activate recently, opens the door to relatively centralized identity authentication for authorities outside the chain. It is possible to construct a comprehensive identity system with the private key on the chain itself, and the earliest, most primitive and original public and private key itself. Such an identity system opens the door to large-scale applications for future users. Otherwise, when it comes to the custody of private keys, blockchain applications cannot be popularized like the general public. It is impossible to imagine that there are 1 billion people in this world who know how to keep private keys.
Seventh, smart contracts are stronger and reduce the difficulty of developmentA smart contract is an independent computer program. If a program is deployed on Ethereum, the operation of this program will be independent of the creator of the program. Smart contracts can solve the concerns of the parties in the transaction about the integrity of the central government, and they can play an absolutely impartial and unselfish role. Although smart contracts carry a lot of hope, independent programs do very little now. How smart contracts can become more powerful is the focus of our attention in the next ten years. Even if computer technology develops in the early stage and is affected by hardware performance and software programming development environment, smart contracts are currently the same. The centralized program development environment is still an overwhelming program. The development of decentralized smart contracts is difficult, the benefits are relatively low, and the incidents of vulnerabilities in smart contracts continue to occur. In the future, the development environment will continue to mature, with more developers participating, and development costs will be further reduced. The reduction in development costs will stimulate the birth of more applications.
Eighth, artificial intelligence plus blockchainArtificial intelligence plus blockchain is also an important topic in the future. Because the algorithm of artificial intelligence program is very suitable for being placed on the blockchain, it becomes an independent existence. At the same time, the most important driving force of artificial intelligence is data, which can help artificial intelligence algorithms to be well trained. All parties of the data need to keep confidential, and this contradiction may be solved by blockchain. At the same time, a powerful artificial intelligence program may override all participants in the system. This is also a feasible solution in the future, that is, artificial intelligence itself can be deployed on the blockchain, and artificial intelligence is no longer owned or belongs to any single system participant. It can obtain a better credibility and authority. If a single company has a particularly large amount of data and at the same time has a powerful artificial intelligence, the challenge to social fairness will be huge.
