'.The chain code itself creates a marble that stores it in the chain code state.The chain code itself can store the data as a string in a key/value pair setting.Therefore, we will string the JSON object in order to store more complex structures. The properties of the Marbles include: ID (unique string, which will be used as the key) color (string, CSS color name) size (int, in millimeters) owner (string) We will create a WEB-based user interface that can set these values and store them in a blo

there used to be a time like to play Mahjong, and sometimes to play a circle to calculate money, so bored to write a mahjong accounting software, there is not much technical content, also did not spend too much time, and then wanted to make it perfect a complete formal software to put out, and later felt that the market is not big, Who played Mahjong have time to point this oh, and then wanted to put the voice into also not empty to do, so empty is also empty, put out open source bar, we will be

I. Concepts Hyperledger is a umbrella project of open source Blockchains and related tools, started in December 2015 by the Linux Foundation, to support the collaborative development of blockchain-based ledgers. Hyperledgerfabric is a subproject based in Openblockchain denoted by IBM. Hyperledger Fabric is a platform for distributed ledger solutions, underpinned from a modular architecture delivering high D Egrees of confidentiality, resiliency, flexi

Object Lock (Method Lock), which is for an object that declares only one memory location of the object that identifies whether the object has a lock, all it locks the current object, and generally an object lock is a synchronized modification of a non-static member variable. or a non-static member method is synchronized, for object locks, different objects access the same synchronized modified method will n

Introduction of Hyperledger Project Hyperledger Project is an open source, collaborative program designed to create block chains for business-to-business and business transactions. IBM is one of the founding members of Hyperledger project, contributing 44,000 lines of block chain code to the Hyperledger Fabric of the first project that is now hatched. Hyperledger Fabric is designed to create an open standard that can be applied to a variety of industry use cases involving business-to-business an

First, the Ethereum Intelligent contract deployment process to build the Ethereum private chain environment, creating a private chain of creation block (not detailed); Start a private chain, generate an initial Ethereum account, start digging (mining requires an account to receive the etheric currency), and write smart contracts, solidity and mix languages; To compile a smart contract, a simple contract for a single file can be compiled online, multiple files need to be deployed with Solc (compi

The full name of the file lock is advisoryfilelock, which is mentioned in the book. Such locks are common. For example, after mysql and php-fpm are started, a pid file records the process id, which is the file lock. This lock prevents repeated running of a process. For example, when crontab is used, a task is executed every minute, The full name of the file lock is advisory file lock, which is mentioned in the book. Such
