When you learn Java, you are often confused by modifiers, which summarize the difference between static final and final.1, static emphasis only one copy, final description is a constant, final definition of the basic type of the value is immutable, but the value of the reference object defined by the fianl can be changed, as an example to illustrate: package difstaticfinalandfinal; class Selfcounter { private static int counter; private int Id=counter++; public String toString ()

The following methods of proving theorems are mainly summed up in the following ways:1) Direct proof: by proving that when P is true, Q must be true for the proof of p->q. 2) Contradiction: The rebuttal method is an indirect proof method, the use of conditional statement p->q equivalent to its inverted ￢q->￢p fact, in other words, by proving that Q is false when

Create a block project using the django-admin startproject block, and create a demo project django-admin startproject demo in the project. The directory structure is as follows: Blockchain Create a Blockchain class in views and create two lists in the constructor. One is used to store the Blockchain and the other is used to store transactions. The following is the Blockchain framework: class Blockchain(object): def __init__(self): self.chain = [] self.current_transactions = [] def new_

publication, and finally who the supporters of the final opinion of who will prevail. This idea is actually a kind of consensus algorithm. However, in the actual process, if the number of people and the number is determined, it is good to deal with, if a large number and the number is not fixed, it is difficult to vote in this way, the efficiency is too low. We need a mechanism to filter out the most representative of the people, in the consensus algorithm is to filter out a representative node

or a question with the attitude of examination questions, but with the attitude of studying mathematics questions. try to explore new things, not limited to the conclusions in the problem. specifically, it is as follows:In general, it is about existence, uniqueness, inadequate conditions, necessity, and necessity.These general statements may be well known and justified, but I just don't know how to do it. I will explain in detail my experiences over the years for your reference. 1. Inspired by

): # Hashes a Block pass @property def last_block(self): # Returns the last Block in the chain passThe blockchain class is used to manage the chain, it can store transactions, add new blocks, and so on, we will further refine these methods.Block structureEach chunk contains attributes: Index, UNIX timestamp (timestamp), trade list (transactions), proof of work (explained later), and hash value for the previous chunk.T

the chain. It can store transactions and add new blocks. Next we will further improve these methods. Block Structure Each block contains attributes: index, Unix timestamp, transactions, workload proof (explained later), and Hash value of the previous block. The following is the structure of a block: block = { 'index': 1, 'timestamp': 1506057125.900785, 'transactions': [ { 'sender': "8527147fe1f5426f9dd545de4b27ee00", 'recipient': "a77f5cdfa2934d

the different points above, combined with the nature of the private chain and the industry chain, we have: Private chain: A closed ecosystem of storage networks, where all nodes are trustworthy, such as most companies within a large group.Industry chain: Semi-closed ecological trading Network, there is a peer distrust node, such as the real estate industry A, B, C, D companies.Public chain: An open and ecological trading Network, which provides a global trading network for both the industry ch
