Most people do not need to re-create a set of blockchain, but based on the existing blockchain underlying platform to develop their own applications, for similar encryption algorithms, peer-to technology, consensus algorithm and so on only need to have a basic understanding can be, temporarily do not need in-depth research. In the text, there are three main blockchain underlying platforms: Bitcoin, Ethereum, and Super Ledger fabric, as well as the app

Block chain enthusiasts (qq:53016353) What block chain is POS and POW If you are a veteran Bitcoin miner or businessman, you must have heard of POW and POS, but currently in the country, but few people understand what this is exactly what the meaning of the block chain, and almost no relevant Chinese materials, small edit vomiting blood writing, is to let everyone better understand these concepts. After reading this article, I believe that you

The better TPS is also for its functional service.Here, we can s

This article is about the last article in the Crypto Currency primer article. Cryptocurrency introductory article mainly for developers, from the theoretical level to describe the concept of crypto-currency architecture, a total of 3. The title of this article in the real writing when the change, did not continue the last hint of "mechanism, the root of the future of society." When writing this article, Bitcoin experienced a crazy rise, currently 3876

timestamp. In this way, the chain is formed. The coolest part of the blockchain is that it uses cryptography to ensure that when any information on the page is changed, we can immediately notice it. This attribute makes the blockchain a good data structure for saving and tracking valuable records. In the Bitcoin blockchain, the chunk contains the bitcoin transaction information, such as Zhang San sending

New book Unix/Linux Log Analysis and traffic monitoring is coming soon The new book "Unix/Linux Log Analysis and traffic monitoring" is about to release the 0.75 million-word book created in three years. It has been approved by the publishing house today and will be published soon. This book provides a comprehensive and systematic explanation of Various Unix/Linux systems and network service logs on the subject of network security, starting from the collection and analysis of the original system

Block chain enthusiasts (qq:53016353) BitPay Open source their Bitcore library package, we can use it to send information based on Node.js to the block chain. The library package allows us to produce bitcoin transactions without having to spend a few days downloading the complete block-chain ledger. Imagine Bitcoin and block chains like pens and new page paper, so you'll need ink to write on the paper (bloc

Shang ·2014/11/27 19:10 Editor's note: colleague Joel Monegro, a well-known investor Fred Wilson, recently attended the New York Bitcoin workshop Hackbit gathering, during which they discussed the impact of the Bitcoin mindset on the world of the next decade, which is contributing to the emergence of a new internet world structure. Not long ago, we also reported Fred Wilson's idea of "Color a

understand the Unix/linux log analysis tips. The language of the book is easy to understand, combined with case scenarios, ease of practical operation. More importantly, system administrators (including various It practitioners) through this book, not only can learn the role of Unix/linux log, but also can extrapolate, standing in a higher perspective on IT Operations and security systems. Only by looking at these problems in a holistic way can we increase the stability and security of the syst

backward 1 letter is the 加密 process, forward is the 解密 process, and this rule is 算法 . This simple encryption and decryption process is called "symmetric encryption." The disadvantage is obviously, must have to call to tell the girlfriend how to decrypt, do not know walls have ears.Of course, the safer way is not to call and handle. Nature is here the private key and the public key, they are long string values, the private key is like a bank card password, the public key is like a bank card acco

In the previous chapter, we mainly described the block chain, block, mining and so on, set the data format of the block, realize how to encrypt the block into the block chain to ensure the effectiveness of the block chain, and we also through the design of a data problem, It is necessary to have a certain computational power (PoW) to prove that a block is a new block in the block chain. In this chapter, we will implement the following features 1. Create a simple wallet (wallet) 2, use our block

hackers, SO 2 + 2 = 5-Although cryptography and mathematics may be mistakenly used. If a system using cryptography is cracked, it is only possible that the designer mistakenly applies cryptography. This is not because cryptography does not work, it's not because someone "cracked" Cryptography-it's not a mathematical error when your bank mistakenly handled your account, and your mom was infected with computer viruses by downloading unfamiliar attachments. is not the same as an email error.

The unprecedented transparency of trade has unnerved financiers. To cut costs, banks are racing to adopt block chains (the underlying technology of bitcoin), but technicians and business people have to make drastic changes to keep this radical technology in line with the rules of the banking world. E-currency Bitcoin was invented in 2009 to create a monetary system that is not controlled by governments and
