permissioned setting, but his communication is at least squared, and obviously is hard to support large network nodes, even in permissioned setting. According to colleague Test, the Hyperledger 100 nodes are about to finish the egg ... PBFT is the abbreviation of practical Byzantine Fault tolerance, which means a practical Byzantine fault-tolerant algorithm. This algorithm is proposed by Miguel Castro (Castro) and Barbara Liskov (Liskov) in 1999, which solves the problem of inefficient origin

Whether sap r/3 needs to be applied when being integrated with other heterogeneous systems When you need to integrate sap r/3 with other heterogeneous systems, you are faced with two choices: one is simple and practical text (solution 1 ),

.), the general use of the Win7 installation CD to repair. Programme 2 traditional dual-system scheme--XP installation Win7 I believe that many users of the loyalty of XP is the same as the author, but Win7 new features are also attractive, so, in the XP installation Win7, naturally become a lot of people's choice. In contrast, installing Win7 in XP is the easiest. Method an XP system with CD-ROM installation Win7 As we all know, the operating system from the low version to the high version

strong symbol and multiple weak symbols, select a strong symbol (this is the answer to the above question, and the initialized int x = 15213 is a strong symbol, int X; it is a weak symbol) ● Rule 3: If multiple weak symbols exist, select any one of these weak symbols (what a terrible situation) Static Library Some relocated target files written in advance are packaged into a separate file, which can be used as the connector input. When the connector

-Number between 0.00-1.00 NormalThe road manager will tell the driver that if the front is more congested, the driver will have to wait, if the front way unimpeded, then the driver can drive directly.Specifically:The numbers between the 0.00-1.00 indicate that the traffic is very good at this time, without congestion, and the vehicle can pass without hindrance.1.00 means the road is normal, but it is likely to worsen and cause congestion. At this point the system has no redundant resources, the
