EnGameChain

1.Blockchain technology
The blockchain is a distributed data system participated by multiple nodes. Its biggest feature is to have no center node, unalterable and unforgeable. Due to numerous participant nodes, it can be said that it is a big account book owning self-confidence mechanism. Both any random data and the nodes in the blockchain have a chance to participate in bookkeeping. As data changes, the system will choose the nodes with the fastest speed of bookkeeping to record this information. Simultaneously, other people are notified to back up the data. In this way, every person in the system has a complete account book. It is because of the features mentioned above that the blockchain technology receives an extensive attention in many businesses that need to guarantee data consistency, fairness and impartiality.
In traditional online gambling business, all data are recorded in the central server. Users cannot see who bet. The detailed computational process of the games is unknowable. Besides, it cannot inquire whether the platforms cheat. Therefore, it is a great problem for users’ credibility on the platforms. EnGameChain brings the blockchain technology into the platform and keeps consumption records of users participating in the game in the blockchain, enabling all data to be reliable, checkable and verifiable. The algorithm of random events relied by the game will be also put in the blockchain and made public simultaneously. Through mutual confidence mechanism of the blockchain per se, self-verification process of the fairness of the platform is completed.
2.Smart contract
For users, smart contract can be seen as an automatically guaranteed account. As the specific conditions are met, the procedure will release and transfer funds.
In the technical level, smart contract is a code of storage, verification and execution in the blockchain. What is different from traditional service code is that all people can see smart contract because these codes and state of them are in the blockchain. In addition, smart contract does not depend on a certain specific hardware. As a matter of fact, the codes of smart contract are executed by the equipment participating in mining.
Smart contract is the assembly language of program design in the blockchain. The people usually compile it from more advanced language such as Solidity and special-purpose language similar to JavaScript. These codes can be easy to make interaction with the blockchain.
The execution of the codes is automatic. As its set conditions are met, smart contract in the blockchain will be executed automatically. Either it is successfully executed or all changes of state are cancelled, which can avoid the execution of the contract part.
3.PoW and PoS
Bitcoin realizes autonomy of property right and decentralization through public key system and PoW. However, if the simple transaction without discretion is made in a way of traceable responsibility as per definite rules, it is not necessary to pursue complete decentralization. For example, open source program does not require each person to independently compile source code but provide the compiled program for being downloaded. A few people are only needed to make compilation for verification. If the bookkeeping system in the blockchain can be designed to be a kind of certain and non-discretionary simple transaction with cryptographic evidence left after doing evil, such bookkeeping mechanism cannot pursue complete decentralization, thus obtaining higher efficiency.
POS is a kind of special transaction, called as coinsake. In the transaction of coinsake, block holders can consume coinage (coinage, coin-holding quantity * coin-holding time) to obtain interest and, simultaneously, a block and priority of using POS to create coin for main network generation. The first input of coinsake is called as kernel and the target agreement in line with a certain Hash is needed. Therefore, the generation of POS block is random. This process is similar to POW. However, an important distinction lies in that random hash operation is completed in a limited space. Unlike POW, it is sought in an unlimited space. Therefore, unnecessary energy consumption can be saved.
