"Hui Xin Yun" For everyone to update the article regularly, "Hui new cloud" It People's industrial chain platform What is ERC-721. Now we see all kinds of encryption cats and dogs are based on ERC-721 created, each is a unique ERC-721 tokens, but ERC-721 in the blockchain world far more than cats and dogs, its larger imagination is to the physical world of assets mapped to the blockchain. This article is to analyze what is ERC721. What is ERC721? In c

user's balance and total, so if we can call this feature before it accesses the Splitdao, We can use infinite recursion to transfer whatever amount of money we want (the code comment flag is XXXX, you may need to slide to see): The basic idea is as follows: Propose a split. Run split. When DAO wants to undo the response to you, call this function to execute split before the undo is complete. This feature will run without updating your balance, this command line we marked as "the attacker wants

The query balance is a read operation on the amount, does not change the data, the CSRF attack cannot resolve the results returned by the server, without protection.　　Several strategies of current defensive CSRFThere are three main strategies for defending CSRF attacks in the industry today:Verify the HTTP Referer field;Add tokens to the request address and verify;Customize the properties

class objects. View the python online files and you will find two sets of Link Libraries for string processing. One is the function in the string module, the other is a string-specific method (string methods ). Although there are some differences between the two, the features are quite repetitive; the focus of our discussion is the string method. We often need to analyze the strings in the file: to split the strings and determine the meaning of the string data based on the given logic. Therefor

The strtok () function should have been encountered by everyone, but it seems that there are always some problems. Here we will focus on it. First, let's take a look at the explanations on msdn: Char * strtok (char * strtoken, const char * strdelimit );Parameters Strtoken String containing token or tokens. Strdelimit Set of delimiter characters. Return Value Returns a pointer to the next token found inStrtoken. They retur
