"Summary" Although Docker and Mesos have become buzzwords, but for most people they are still unfamiliar, let's explore the powerful destructive power of Mesos, Docker, and Go, and how to create a bitcoin mining with 300 lines of code System.Nowadays, for most it players, Docker and Mesos are both familiar and unfamiliar: the familiarity with these two words has undoubtedly become the focus of discussion, and the strangeness is that these two technolo

JavaScript implements blockchain and javascript Blocks Almost everyone has heard of cryptocurrencies like Bitcoin and Bitcoin, but only a few people know the technology behind them. In this article, I will use JavaScript to create a simple blockchain to demonstrate how they work internally. I will call it SavjeeCoin!

Although the codec framework is not part of the Netty micro-kernel, it is essential to extend the codec framework through

used as a buffer for storing decoded UTF8 characters. It is important to note that 512 is not the number of bytes, but the number of characters, some UTF8 characters need only one such character to be able to represent, some need 2. The smile character used to construct buffer in the sample code requires 2 such characters to represent 4 bytes to store. So the number of bytes that buffer can store is 512*2=1024.If the buffer to be

block Chain Intro What the blockchain really is. Blockchain (English: Blockchain) is a distributed database, originated from Bitcoin, Blockchain is a series of cryptographic methods associated with the generated data block, each block contains a number of Bitcoin network transactions information, to verify the validity of its information (anti-counterfeiting) and the next block generation.

The series of articles I have put on GitHub: blockchain-tutorial, Updates will be on GitHub, and may not be synced here. If you want to run the code directly, you can clone the tutorial repository on GitHub and go to the SRC directory to execute make . In the previous article, we constructed a very simple data structure, which is also the core of the entire blockchain database. The blockchain prototypes that ar

IntroductionIn the previous article, we implemented the blockchain workload proof mechanism (POW), as much as possible to achieve the mining. But there are many important features that are not implemented from real blockchain applications. Today we will implement the storage mechanism of blockchain data and save the blockchain data generated each time. One thing to note is that the blockchain is essentially a distributed database, and we don't implement "distributed" in this case, focusing only

Blockchain Enthusiast (qq:53016353) The blockchain technology used in digital currencies is already well known in China, but technical research has not been carried out effectively, and most people are aware and aware of the extent to which many people in the Bitcoin circle can do so much in the digital currency. One important reason is that most of the core data of digital money is in English, and few people can read such a complicated English materi
