and service side rely on a globally unique identity to access the data for the purpose of interaction. When a user accesses a web app, the server-side program creates a session as needed, which can be summarized in three steps:
• Generate globally Unique identifiers (SessionID);
• Open up data storage space. It is common to create the corresponding

Memory can only be used inside functions, memory declarations are used to tell EVM to create a (fixed-size) area of memory at run time to use for variables.
Storage are stored in the block chain in key/value form, while memory is represented as byte arrays about stacks (stack)
EVM is a stack based language, the stack is actually in memory (memory) a data structure, each stack element accounted for

Effective data protection on the cloud
However, we have encountered one of the challenges brought about by the asymmetric development of the cloud environment. In the past, one of the most important tasks facing IT managers was managing encryption keys. Green House Data is a cloud hosting and Data center service provider. Cortney Thompson, chief
Data center has become the biggest energy consumption center of many companies, how to reduce energy consumption, how to improve utilization efficiency, how to reduce operating cost? These are based on environmental protection and energy conservation considerations, so that green storage has become a new concept in recent years, a novel theme.
By the year 2008, Gartner argues, the current 50%

Second, the memory database is only the current memory calculation within reach of the results, the long-term development of memory computing in the flow-type processing (stream processing). In addition, the difference between memory calculations and traditional memory databases is that memory computing is designed for distributed, resilient environments,
