DEVCON2: Marley Gray at Microsoft "A Circle of Developing Cryptlets"

Reporter: Lydia

Marley Gray from Microsoft showed developers the implementation of Cryptlets, an overview of Cryptlets, and a live demonstration of building a Cryptlet with Solidity.

Ethereum Blockchain as a Service (Baas) was launched in December 2015. Microsoft was the first to apply Bitcoin. We are constantly learning and hope to embrace Ethereum. Last year, we spent a lot of effort to sponsor DevCon. Microsoft is committed to Ethereum. Ethereum is a citizen in the distributed ledger. Customers are using it and hope that we can provide services. Everyone should cooperate. I hope everyone will actively contact us.

I want to announce what Bletchley version 1 means. Ethereum plays an important role, the distributed ledger is at the bottom, and any customer can join our consortium chain with just one node.

(I started preparing at 4 o'clock today)

We launched Cryplets in June to bring blockchain into the enterprise. Large enterprises want to know how to use distributed networks.

Cryplets is one of our methods. Distributed ledgers are also going through growing pains. We have identified some key requirements, such as key management, which is difficult to do correctly. Security issues were rarely discussed last year. In addition, this type of technology is now used most in the financial industry, and is also being studied in the medical field.

How to inject data into the blockchain? We need trusted execution so that developers can make the right decisions, distinguish the issues they are concerned about in the code, and have a market observation mechanism. If an algorithm wants to be protected by IP, and we want the blockchain to expand the network and have the benefits of a distributed ledger, there are also very complex interactions. Our host system, the Ethereum blockchain system, can achieve good interaction, and we need to further improve it.

We need to have more options, not just one platform, one language, to get secure data.

Oracles have been around for a long time, and Cryplets not only protect data security, but also protect execution security, integrate operations, and provide a marketplace for developers. We have a lot of infrastructure.

Cryplets network, easy to use in development. Discover Cryplets needs and achieve business goals through coding.

Use case: Smart contracts can be laid out based on events. I want C to do something for me. We subscribe to an event to wake me up at 4 o'clock. If it is open, it will give me the price of gold, and it will give me relevant information, the value of not purchasing, and the test host address, which can record the contents of all smart contracts.

The second application adopts a three-level architecture. This is a controlled application. The smart contract declares which data to pursue and what to do is to insert it. The controlled Surrogation can be listed and can be run on several nodes. If the bank enters the transaction and needs better performance, such as better algorithms, it can run on Cryplets, while ensuring the performance of the distributed ledger.

This is a smart contract, the yellow part is the force. The market is open to get interest rates and gold prices, just request Cryplets, you can refer to Cryplets, and ensure the signature.

Contract Cryplets can observe the market, perform execution, and record the status in the smart contract itself. You can wonder why Android is used for this. Hardware security is very important. A part of the chip can run code. You cannot destroy the data and interfere with the execution.

Enclave, through contracts with large banks, can ensure that the code runs in an isolated environment and provide security, but its scalability is not very good and it can be deployed on different application networks.

NET Core is open source, there are many languages ​​to choose from, and the EVM itself has entered the Enclave, and huge amounts of data need to be executed securely.

Five advantages

Ensuring secure execution with Enclave

Securing data providers with end-to-end proofs

Provides scalability and flexibility when executing code

Developer-friendly development environment with a wider ecosystem.

Standardized approach, while being able to access external resources,

There is a market for development scale that can scale not only the solution but also the cloud.

This is very attractive for large enterprises. The Cryplets white paper will be released today. It is 26 pages long and describes Cryplets in detail. It is impossible to start writing it tomorrow. What you can do now is to look at the Ethereum consortium chain network, which can answer very simple questions. What is a consortium chain? We have done a lot of work. It seems that it is easy to have a chain. As long as there are nodes, you can build it, including the network settings and how to automate it. It is fast and convenient. We have deleted some of the steps. You must understand how to deploy the Ethereum network. You only need to answer 8 questions.

There are about 100 nodes on our alliance chain. It used to take two days, but now it only takes 20 minutes to deploy a very large network.

(Applause)

Each member is on its own sub-network and can only access miners from the transaction node. We have also thought carefully about this, and there is an Ethereum pool that can quickly enter the portal.

Finally, this is our roadmap. In the summer, we released Baas, which can be used by other applications, not only Ethereum. We will release more formal verification or related tools to promote the community's efforts in this regard.
