[Summit] Marley Gray, Director of Business Development and Strategy at Microsoft: Microsoft's Blockchain Platform - Bletchley

Reporter: Pencil lead

Good morning, everyone! The PPT will be out soon. I would like to thank you for the opportunity to be here. In fact, I also gave a speech at Devcon2, the second Ethereum development conference, mainly about a platform developed by Microsoft.

First of all, I want to introduce what Middleware is. Last year, at the first Ethereum conference, we released our BAAS, which is a blockchain-as-a-service platform. We are also very excited to announce some features of our Dapp. According to our users' feedback, there are many technical details here, and they hope to try them. So I hope to help everyone use our platform better in the end. If you don't try, you can't innovate. Of course, if you don't innovate, you can't survive or seek long-term development in such an industry.

I think that our industry is actually very good, because we have a very open source infrastructure, and we can use blockchain to achieve point-to-point transactions between individuals and organizations. Of course, we know that blockchain itself has some missing parts, and it is obviously not enough to solve these problems only through the blockchain platform. For example, let's talk about databases. As a database, it actually has many functions. So we talked to our customers and then we learned what they thought was missing from the blockchain. Of course, they listed some of their ideas for us, although they were not very comprehensive.

First of all, for example, they need secure identity authentication, whether it is for their own identity authentication or the identity authentication of the items I hold. We know that these are actually very difficult problems to solve, so we need to store our keys properly, and we must ensure the security management of our keys throughout their life cycle. In fact, as Microsoft, we also have such problems, so we hope to improve and innovate the way we create code, so that it is easier for us to write more secure and more effective code. This is a process, so in the process of fulfilling our promise, we also need some tools and data services.

I am very happy to announce the first version of our Bletchley V1. As you can see, Bletchley is actually the name of a worker. Of course, the worker who gave this name is also a very important cryptographic figure. As you can see here, I have listed some relevant content about Bletchley in this table. We said that on such a platform, we hope it will be a core content of our blockchain. Because the spokesperson from Hyperledger just mentioned that there is actually no unique blockchain. In fact, all of our chains should work together so that the collaboration of blockchains can be established through different channels. So in this case, we can innovate freely, which is what we and our partners are currently doing.

On top of that, we have a team that is also very helpful. They created a platform with us. This platform actually has nothing to do with blockchain. Any blockchain can operate on this platform. Of course, there are also some of our solutions, so the first version of Bletchley is actually the block network of the Ethereum alliance chain. If you put your code on the network, how do you ensure the security of your code? Because we know that there are still many problems with the code that need to be solved. We see that sometimes there may be some information that needs to be kept confidential. Here we will ask 8 questions, and this question will be asked in 5 to 8 minutes. This question will be asked to 4 to 100 nodes on the network, and the questions are asked in a very serious way.

In fact, here I list the network in the lower right corner, which is a very private or private Ethereum consortium chain. We know that we can now interact with hundreds of intersections, and let's see how their consortium chain should be executed.

Another point is the Flebic cloud, which actually hopes to help blockchain create some information. I also mentioned Cryptlet in the meeting two days ago. Generally, in this case, there will be smart contracts to help us realize the function, and we will also have an interval, such as every 15 minutes. All of these are external market information we are talking about. Of course, we can use an internal system, such as a CRM system, to analyze or collect our customers' data.

Of course, we just mentioned some trusted data. Of course, do we also need such trusted execution? Of course, we say we do, because trusted execution is very important for all parties, and this can also be achieved through isolation or other manipulation of applications. So we hope to protect the intellectual property of applications on our blockchain. At the same time, we also hope that our transactions can be run on all nodes. This means that we need to expand our algorithms to achieve maximum performance. We also need to do some more complex interactions. We will have some distributed applications. You can embed this application on multiple blockchains. You want your transaction to be implemented by submitting it to all blockchains. This is a very complicated thing. In fact, we have been conducting research in this area for a long time. Of course, we also hope to improve the performance and scale of existing enterprises using blockchain.

Next, let's take a look at how Cryptlet works. Here we have a network of enterprise alliance chains with some blockchains on it. Every time the market is stagnant, if the market is open today, we will start a smart contract. For example, we need to get the price of gold, which is very important, so in this case, we will intervene in Cryptlet. If we want all three counterparties to agree, we need such an Oracle.

Here, let's say the bank is Oracle and the hedge fund has some problems. So in this case, we need people to believe that our protocol is a secure protocol, or that our host is a secure host. At the same time, we also hope that the Oracle can be tested and verified, and ultimately we let all trading parties believe that the system can run safely.

So here you can see that there is actually a verified host running on our Oracle platform. Here we can simply compare the difference between Cryptlet and Oracle. In fact, Cryptlet is a very standard infrastructure. We can define it very clearly, and it can be used as a platform for developers to create the database or library they need. For example, if we need to create some new applications for this market, we can also use Cryptlet to achieve it.

This one is a bit more technical. You can see that there is a node of the blockchain here, which is implemented through Cryptlet. We can see that Cryptlet has a trusted envelope, so this can be run on your desktop computer, or on different devices such as your laptop. This is the Fabric of the Bletchley Cryptlet we talked about. We can see that if it is an existing supply chain, because we actually support Ethereum, of course we will also support other types of blockchains. So here you can see that we can break down your different concerns, and we can transfer your Mist between different data. These capabilities can be achieved through Fabric, and of course we can also implement all these operations in a consistent way.

When it comes to the scale of the enterprise, it is related to the enterprise alliance chain we are talking about. Here we have a WW super-scale cloud, which is the Azure cloud we are talking about. You can take a look. In fact, we have deployed such an Azure cloud in more than 30 regions around the world, and the distribution of clouds is also growing every year. The execution is very fast, and there are many options at the same time. You can also improve the elasticity of the database on the blockchain network and expand it to other geographical locations. For example, we have a data center here, which is hosted by 20 billion Net. We have customer data and transaction data, which may have to be in China. But if you have a global blockchain, you can still deliver. We have many such data centers, these are just some locations. We have about 100 data centers around the world, most of which are very large-scale, highly redundant data centers. You may have to come and see it in person to know how big the data center is. The structure of our blockchain covers the world.

Some key points, what does this mean for the blockchain, for the ecosystem of developers and enterprises? What does it mean for enterprises to have a reliable blockchain network? The first is on-demand, secure execution. We can guarantee its security, as well as its elasticity and high performance, and it is a secure data provider, you can get market data, and you can publish your own market data. You can create and consume some data, so you can compare prices in real time.

Scalability and flexibility mean that scalability and flexibility can be achieved when the code is executed. We have a Scale architecture that allows you to isolate the problems you are worried about. You can also implement a certain architecture for your solution to achieve scalability. At the same time, we are a developer-friendly ecosystem. We support all blockchains, and we will support the tools they like, so that these resources are scalable. You can create your own library and publish it so that others can find your library, and you can also find existing libraries. If you need some application functions, you can find reference code in the code, and you don’t need to worry about where the Cryptlet is, whether it is safe, and whether you can get the high performance I need. There is also a standard way to publish and obtain external resources, which is also a very important part.

Finally, I would like to introduce to you our Microsoft roadmap. At the beginning of this year or in the fall, we released a general blockchain-based service and Dev Test Labs. It is not only based on enterprises and developers, but it is mainly based on alliances, so Dev Test Labs can be created locally and then created safely. Now we have announced Bletchley V1. We and the Ethereum community can release it to the open market together, while improving security and the life cycle of the code. Later we will have Bletchley V1. Thank you for inviting us. I hope you all have a good day today. Thank you!
