Understanding the concept of blockchain is simple (block chain, trading chain block): It is distributed (ie not placed on the same machine, different network devices on the) database to support the hosting record of the growing list. However, it is also easy to confuse blockchain with the idea that we are trying to help him solve the goal--at that moment in people's minds, the word is pretty strong about trading, contracts or smart cryptocurrency conc

explore. At present, the cross-chain technology in the blockchain is still in the research and trial, and is not used in the scale, Elwin try to introduce some current research cases of relevant technology. one, side chain The side chain is a new blockchain based on the anchoring of bitcoins, just as the dollar is anchored to gold bars. Side chaining is the goal of implementing crypto-monetary financial ecology in a converged way, rather than rejecting existing systems like other

Introduction to Mining The term mining is derived from the analogy between cryptocurrency and gold. Gold or precious metals are rare, and electronic tokens are also the only way to increase the total is to dig mine. So is Ethereum, and the only way to release it is to dig mine. But unlike other examples, mining is also a way to protect the network by creating, validating, distributing, and propagating chunks in the blockchain. Dig aether = Protect Ne

X dollar, then the chunk B1 in the economy is ultimately determined, and the margin of the security of the password is x $. Let's imagine X equals $70 million. Basically, if a chunk is finalized, then the chunk becomes part of the chain, and the fact that you want to change it is very, very expensive. The workload proves to be less than this effect, which is also a unique feature of the proof of rights. Our intention is to make the 51% attack very expensive, and even if most of the validators w

_ Stdcall: _ Stdcall is equivalent to the Pascal call convention that is frequently used in 16-bit dynamic libraries. In 32-bit VC ++ 5.0, Pascal's call Convention is no longer supported (in fact, it has been defined as _ stdcall. In addition to _ Pascal, __fortran and _ syscall are not supported). Instead, they are replaced by the _ stdcall call convention. The

-mangling scheme, so different compilers use different, for example: Borland C + + Mircrosoft C + + is different, And maybe different versions of the compiler their name-mangling rules are also different. In this case, the target files are compiled by different compilers. obj is not universal, because the same function, using different name-mangling, will have different names in the obj file. If the function renaming rules in the DLL are inconsistent with the renaming rules used by the user of t

Three key function call conventions and key function call conventions After the advanced language is translated into a machine code, the computer cannot know the number, type, and hardware of the parameters called by the function. In addition, in C ++, the function naming method is different from that in general C language because of overload. This method is called name adaptation. When calling an interface between a function caller and a function, especially when calling an interface across lan

dlldir _ stdcall bubblesort (byte * array, int size, int elem_size, comparefunction cmpfunc ); Void dlldir _ stdcall quicksort (byte * array, int size, int elem_size, comparefunction cmpfunc ); These two functions accept the following parameters: · Byte * array: pointer to the element array (of any type ). · Int size: number of elements in the array. · Int elem_size: the size of an element in the array, in bytes. · Comparefunction cmpfunc: a pointer to the callback function with the above proto

It passes an array with five elements to Bubblesort () or Quicksort () along with the pointer to the callback functions. int main (int argc, char* argv[]) {int i; int array[] = {5432, 4321, 3210, 2109, 1098}; cout If I decide that I want the sorting-to-be-done descending (with the biggest element first), and all I had to-do are to change The callback function code, or provide another that implements the de

, cis.equals(s) returns TRUE. The problem is that although the CaseInsensitiveString equals method in the class knows the normal string, the Equals method in the string class ignores the case-insensitive string. Therefore, s.equals(cis returns false, which is a clear violation of symmetry. Suppose you put a case-insensitive string into a collection:Listlist.contains(s)What was returned? Who knows? In the current OPENJDK implementation, it returns false, but this is only an implementation artifac

then understand the real behavior of the system. Therefore, the focus of reading code is not to read each line of code, but to efficiently through exploration and reading, so as to understand the system's architecture and behavior patterns.

): do_something () 1.3 Internationalization: Perhaps you have also seen that "_" is used as a function. In this case, it is commonly used to implement the function name of the translation lookup between internationalized and localized strings, which appears to originate from and follow the corresponding C convention.

_ stdcall uses the standard calling convention so named because all Win32 API functions (could t the few that take Variable Arguments) use it. functions that follow the standardCalling convention remove the parameters from the stack before they return to the caller. this is the standard convention for Pascal. but in C/C ++, the calling

When you call a function in a DLL, the following dialog box is displayed: Microsoft Visual C ++ debug Library: Debug error:Program :...Module:File: i386/chkesp. cLine: 42 The value of ESP was not properly saved stored ss a function call.
