company, explained: "Until recently, the selection of wireless infrastructure for expansion of small and medium-sized enterprises was very limited, that is, multiple independent access points were managed and configured separately. As enterprises constantly expand their wireless infrastructure by deploying multiple independent access points, this naturally leads to management and security nightmares. Since each access point must be managed independently, such deployment greatly limits the scala

The above is the simplest of a smart contract, the smart contract to achieve a basic function, that is, input N, return 8*n.So what do we need to do with him? This involves a very useful tool, browser-solidity.

Local virtual machine debugging, is not connected to any one node, in memory virtual out of an Ethereum node for debugging, the advantage is fast, simple configuration, the disadvantage is because it is only virtual debugging, may finally put on the real blockchain node to run the smart contract will be different from the expected results.

Currently Browser-solidity has two common debugging methods, one is to use local virtual Machine debug mode, one is connected to the local private chain for debugging.

Application Environment of Layer 2 smart Switches
Because L2 smart switches are L2, they can only be deployed on the edge of the local area network to serve as access services for clients. Layer-2 smart switches are used to cope with the complex data,
vulnerable connections (that is, passwords) for authentication systems. The industry is in great need of technology that can replace passwords. With embedded cryptographic processors, smart cards provide a very secure and easy-to-use authentication mechanism.
However, the deployment of smart cards also poses a unique challenge. The entire industry needs better products to

So far, many people have heard of similar reports, that is, the loss of personal data or sensitive data due to the theft or loss of portable computers. Portable computers regularly lose data. As identity theft is becoming more and more serious and regulatory compliance is more and more important than ever, comprehensive protection for all data in mobile computing systems will become a top priority.
