10 ⽉ ⽇ 11 ~ 13, sponsored by the China computer society, block chain of China computer society
Committee, the China electric ⼦ ⽹ collaterals information security technology co., LTD., ⻄ south ⼤ study of finance and economics, division
The 2019 CCF block chain technology branch co-hosted by guodin data science institute will be completed
For ⾏. China ⼯ cheng yuan yuan ⼠ ⼠ Anderson, court issued the key technology and block chain area
Regulatory challenges of block chain "keynote speech, he said that China's block chain technology research hotspot will be
Focused on the key technology of alliance block chain, chain blocks regulation technology ⽅ ⾯. Alliance block chain
In addition to four key technologies that need to be researched by scientists, there are also technologies for data collaboration up and down the chain, which
⽅ to ⼀ under the stage of development.
Core view:
1. Nuclear ⼼ league chain underlying platform are performance, can be ⽤ privacy and security;
2. Chain chain synergy technology is the data for the future development of ⼀ important ⽅ to;
3. The regulatory technology of blockchain is the key to the healthy and sustainable development of blockchain.
The following is a speech all ⽂ (according to the field of shorthand and record the ⾳ finishing) :
WeChat ID: XuS venture capital 1
Today very honored to, also very ⾼ hing to we ⼤ will this time. My report topic ⽬ is "union block
Chain key technologies and regulatory challenges of blockchain. Just before the said ⾯ ⽐ is poor in this year
Poor head, especially last year, in fact I think also is not the case, the block chain is developing in spring ⻛,
⽐ such as "⼗ 35 planning" in our country have to block chain, quantity ⼦ communications, ⼈ ⼯ intelligence as
Heavy ⼤ ⽬ into ⾏; 2019 2 ⽉ 18 ⽇ ⼈ ⺠ ⽇ newspaper front page mentioned block chain is "new
With the spirit of modern information technology.
Block chain, this simple ⾥ I share with ⼤ home ⼀ next. Introduction is the traditional system with block
Chain system ⼏ characteristics, traditional system each other ⼼, tampering with data reconciliation, etc.,
This is the opposite of the blockchain system. about nuclear ⼼ value chain blocks, the ⾥ has many
Experts I not much said, it has promoted many ⼼ collaboration efficiency, to mediation, improve ⽅
Trust, data untamable, traceable, auditable, and so on.
Blockchain technology research hotspot China and the international slightly different, China's main research hot
The point is focused on the key technology of blockchain alliance, and I think the supervision technology of blockchain is also
Is ⾮ often important. Why do you say block chain ⾮ regulation technology is often important? With the spirit of nature
Well, like traffic ⼀ sample, when the police did not stand, ⻋ ⼦ open, traffic order
It will be too good. I this ⾥ mainly want to talk about the key technology of alliance block chain.
Alliance block chain of 4 major technologies
⾸ alliance first block chain ⾼ performance it is ⾮ often important. When you have a league chain, chain ⽅
⾯ etheric lane per second ⼏ ⼗ pen, this point is not enough. Now, if ⼤ scale should be ⽤ come up
The best of the domestic league chain can be tens of thousands of points, ⼏ per thousand to tens of thousands of performance. ⼤ gauge
The performance of the nodes of the module, or the amount of data in the module, will drop dramatically, too
Block chain waste and performance not ⾏ shortcomings. Key technology ⾼ performance needs in various ⽅ ⾯
Into ⾏ technological breakthroughs, including ⾼ consensus algorithm performance, including ⾼ intelligent engine contract, too
Including the consensus of the new mechanism, the hope can ⾼ consensus efficiency and safety, mainly is, of course
To ⽀ hold various ⽹ ⼤ scale main ⽹ of complex structure. There was also a hot spot of research on hardware and software cooperation
With optimization, which is also ⾮ often important, like AI ⼀ sample, without core ⽚ AI is very troublesome.
The first block is the most critical ⼆ a chain security privacy key technology. In China to ⽤ ⾸ to full ⾯ first
⽀ the encryption algorithm and standard in our country, it is certainly no problem. Business should be ⽤ need platform business number
According to privacy protection, can pass the namespace ⽅ type in the physical ⾯ into ⾏ business data points
Yeah, it's worth studying. There is also a more fine-grained privacy transaction mechanism that implements transactions that can be verified however
Not ⻅. And based on the credibility of ⾏ environment technology node key management and data encryption
WeChat ID: XuS venture capital 2
Storage, data organization technology such as Angela merkel, based on DAG, prevent ⽌ ⽂ been tampered with. League chain
The first ⼆ key technical safety and privacy is ⾮ often important.
The third key technology is the key technology of ⾼ ⽤ can be. This ⾥ ⼀ a dynamic members
⼊ mechanism, and quick recovery after the node failure mechanism, the ⾥ will touch in a distributed system
That this also ⾮ often important, not the entire system to stop node, should be in real time
The state. When I wanted to delete one of the outdoor spirit nodes, I couldn't stop it
Can stop. And go to the ⼼ alliance ⾃ cure management mechanism, how to do this? Is tong
Too much ⽅ proposal a vote ⽅ method or other ⽅ method, all of these have the mechanism. ⼈ can conceive
No doubt, whether the alliance chain can truly achieve a fair mechanism of management,
But the league in the chain is much ⼼ will doubt, this also ⾮ often important. And the thermal ⾼ effect
For switching mechanism, this also is the key technology of league chain after, is ⾮ often important.
The fourth key technology is the key technology of ⾼ extensible. With that intention, it was programmable
⾔ make ⽤ ⽀ hold a variety of programming language. The ordinary programming language ⾔ the better, of course, such ⼤ home is
Will ⽤ very ⽅ then. The first ⼆ ⽅ type extensible storage, can ⽀ holding multi-type, multiple groups
Woven data trusted storage. The third is to provide credible external data sources ⽀ hold ⾔ machine clothing
Services. Fourth is ⽀ hold across the chain, and heterogeneous isomorphism chain chain of cross linked together, this also ⾮ often heavy
Want to.
This ⾥ ⼀ ⽐ relatively, I purposely put forward Hyperchain, technical performance in the league chain ⽅ ⾯,
Our domestic is also done ⽐ is better. For example, like Hyperchain ⽐ now all performance
Is is superior, is good this year with various platforms ⽐ more abroad.
Chain chain data under collaborative technology is one of the important ⽅ to league chain development
Industrialization should be ⽤ league chain can also be at home, in the field of ⾦ ⾏ industry, legal, medical
Domain, energy domain, entertainment domain, notary domain, etc., what do I want to talk about? although
Feel cooled block chain this year, but our country is the chain of the alliance should be ⽤ since this year
There are so many, these should be ⽤ just ⾦ melts, the block chain should ⽤ or abroad
A little bit different. ⻄ ⽅ blocks the development of the chain is basically based on ⾦ innovation up other ⾏ industry
New, ⽽ besides ⾦ melting innovation in China, what is more important in various ⾏ industry should ⽤, ⽽ and now
In good ⼏ domestic league chain platform, also ⾜ with ⽀ ⼀ some should ⽤ now. ⾯ before I speak
To performance can be tens of thousands of nodes, of course, this is very extreme cases, ⽽ and can do it
Tens of thousands of frequencies per second.

Recent ⼀ alone ⼦ is ⾮ often good, government affairs ⽅ ⾯ reserve ⾦, housing and construction in China
Silver ⾏ made reserves ⾦ management, 491 cities of the country's reserve ⾦, equal to 491 nodes
Now even in ⼀, regardless of what the city's reserves ⾦, regardless of the reserve ⾦ of each
⼈, can be different very ⽅ operation. This if not ⽤ block chain ⽆ method to imagine before, you are
All the data on ⼀, or is each ⾃, I think this is very good
⽤.
In addition to four key technologies that need to be researched by scholars, blockchain alliance also includes data collaboration on and off the chain
Technology, which is under ⽅ to ⼀ stage of development.
Is on the left is the CAP theorem, ⼀ consistency, but ⽤, partition tolerance, originally I do the ⽅
⾯, distributed ⾼ performance of real-time computing, with particular emphasis on ⽤, partition tolerance.
However, the theory of ⽆ how each system is in three ⼀ a balance point, if emphasize ⼀ consistency,
That might be in can ⽤ sex and partition will tolerate sexual ⼀ points, so different should ⽤ is particularly close
Note.
Block chain also impossible to three ⻆ model corresponding to come over, it is to the ⼼, scalable,
Security. The same process of fully neutralizing would have been more challenging with respect to security
⻆ point. With that said, both the traditional information system and the blockchain system have inherent limitations
Sex. ⼀ ⽅ ⾯, block chain system needs through chain system under extension can ⼒ computing and storage. On the other
⼀ ⽅ ⾯, under the existing system linked with block chain docking are needed to solve the information island and tamper-proof, etc
The problem.
If as ⼤ scale should be ⽤ now, I think the most important should solve asked under the chain on the chain
The so-called blockchain on the chain is all the traditional information system below the chain. How do we
What type ⼊ embedded block chain system to the traditional systems now ⾥ ⼀ some problems to solve it, or
In turn ⽤ our block chain system put the traditional information system. Just like I said
Reserve ⾦ ⽬, it is point to point 491 points is completely block chain system, under ⽽ ⾯ reserves
⼜ ⾦ system is one of the traditional ⽹ winding should be ⽤ system, structure, so block chain in ⾯, under
⾯ have other, which in turn can also put a chain of block system ⼊ traditional embedded system, under the chain chain data
Collaborative requirements can be especially important. Request chain on the chain down the data, if you can coordinate can be true
⼀ consistency and relevance, this ⾮ often important.
Before ⼤ home can query ⽂, ⽬ data under the chain chain synergy of technology at home and abroad is just up
Step, also have ⼀ some collaborative research, including the side chain and channel the state, to mention ⾼ performance and calculation
Can ⼒. It's a bit like cloud computing and edge computing. Now the data is good, at least on the blockchain
WeChat ID: XuS venture capital line 4
Leave a channel for other data. Cross - chain technology in order to increase interoperability between chains and
Scalability. Chain calculation under, can ⼒ ⾼ data privacy protection. It is also a ⾮ often important
We can't just think about the connection between the system on the chain and the system on the chain, how to protect the data privacy
Protect also want butt joint. With the addition of chain-down storage, what was the original system storage
It should be studied.
Under the chain chain data ⽅ to four ⼤ synergy technology development
⽅ to its development, standards, data fusion under the block in the chain of chain and chain synergy of the model box
frame, ⽬ before need to research the following points:
1. ⼤ ⾼ performance scale peer-to-peer ⽹ collaterals. Around the block chain should be ⽤, originally ⼤ scale point to point
⽹ collaterals, this is the most important, because the chain of blocks is point-to-point transmission. if
⽹ winding technology no breakthrough, block chain system performance is difficult to ascend.
2. Modular security cryptography protocol. Blockchain is distributed with passwords. Security tight
Modular code learning agreement, block chain embedded ⼊ ⼦ system, modular security of cryptographic protocol
Research on ⽅ ⾯.
3. ⾼ programmable calculation engine performance. We hope ⽤ different intelligent contract ⽤ plait
Cheng ⾔ to make up, since ⽤ ⾔ different programming language, you may need a ⾼ programmable computing performance
The engine.
4. Definable data distribution protocol.
These data should be under the chain chain ⽅ to collaborative development.
⽬ to say also is pretty good, we had ⼀ middle experiment, now basically can provide
Domestic, ⾃ Lord, controlled, perfect China ⽀ ⽶ cipher algorithm, provide the system of chain chain
With the collaborative service technology stack, it couldn't be said that with its standard framework, it gradually provided many technical services
The online service of the service stack includes: the scale trusted storage, the number of cluster nodes can reach tens of thousands
Points. The experiment was done in China mobile. Our team hopes that with the current technology, it can be
Tens of thousands of nodes, number, did ⽀ are smart contracts across different chain interoperability through ⽤
Chain services. "Data can be ⽤ ⻅" data sharing has been preliminary implementation, however, the theory of ⽆
The technology is not enough. I think there are still very ⻓ way to ⾛, so block chain technology
I think this is just the beginning, not just every single point of technology, but the whole system.
Blockchain regulatory technology
Regulation, finally I want to talk about block chain block chain ⾮ regulation technology is often important, just like me
⾯ talked about before, especially in China should be ⽤ ⼤ scale, block chain ⽬ item later, you didn't
WeChat ID: XuS venture capital 5
Have good regulation, who all dare not risk the ⻛. With my spirit, I had no spirit
Tube, like ⻢ no site ⼀ a traffic police on the road, or no traffic light." Do you think ⾃
⼰ had better not police, it is best not to traffic lights, ⻋ ⼦ can open very quickly, in fact is not
⾏. ⼤ home all know the importance of supervision technology, have ⼀ "north ⼤ YueXin" event is written ⼊
Ethereum, you can't tamper with it. What do you do? Have ⼈ data down everywhere. The chain of public
It has become the communication medium of new media, because the public chain itself has been de-centralized and cannot be replaced
Change, cannot delete, low cost characteristic. I remember I have ⼈ calculate, in the "north ⼤ YueXin" ⼏
A message in ethereum seemed to cost only $0.17
Come to think of it, but ⾮ often cheaper price. ⽤ block chain to spread harmful information, ⽹ collaterals rumours
⾔ inflammatory, offensive information, and will bring to block chain industry layout and development of the technology is not
The influence, will affect us, this is ⾮ often important. Itself will bring superintendent department ⻔ chain
It's a great challenge.
Any good technology or ⼀ ⼯ needs to be correct to make ⽤, can play the most ⼤
The value chain blocks regulation more ⾼ requirements are put forward.
We except for the block chain technology itself, perhaps we need to really have ⼀ ⽅ very well
To the. Let's look at how blockchain regulation, so called security, blockchain security is the most important
Is the block chain system security, anti-attack, etc., in addition, block chain content, public chain
Has become a media, what else is possible? It is similar to the consciousness form of "north section yuexin"
State, content regulation is needed, if we can ⽤ our technology?
2019 ⽹ letter do go to the "block chain information service management regulations", we learned this
Rules and communicate with ⽹ letter do feel block chain development has two ⽅ ⾯, ⼀ is ⼤ rules in China
Should ⽤ should ⽤ block chain a module to the economic construction, mainly ⽤ chain alliance, its regulatory relatively
Control, the challenge to security ⽐ is better. But we should also be ⽀ male chain technology of hair
Exhibition, participate in international competition, this also is ⾮ often important.
⽬ before although block chain regulation has been ⻅ effect at the beginning of this year has unveiled the first ⼀ batch of 197 districts
Piece of chain information service for the record number, but the road or ⾮ ⻓, often before ⽬ block chain
Tube technology development trend has the following ⼏ points:
1. Tracking and visualization of blockchain nodes.
2. Penetration supervision technology of alliance chain.
3. Active discovery and detection technology of the common chain.
4. Chain by chain architecture and standards.

only provides technical solution ⽅ case, ⽽ and relatively reliable, ⽆ ⾮ ⼀ point, is the difference in degree only
Have such ability in actual should ⽤ is likely to block chain on this technology, block chain regulation here
A matter ⾮ often important. Professor we need everyone here to research ⼀, provide ⼀ some ⻔ for supervision department
