区块链技术的特性
区块链的基本特性主要体现在5个方面：
1）去中心化：以分布式网络为基础结构，对数据进行验证、记账、存储、维护和传输等操作，利用纯数学方法建立节点之间的交互信任关系，进而形成去中心化、可信任的分布式系统；
2）时序数据：块链式数据结构携带时间戳，为数据添加时间维度，使得数据能够验证与追溯；
3）集体维护：区块链系统使用特有的激励机制以保证系统中所有节点均愿意参与区块的验证，在此过程中采用共识算法选择特定节点，为区块链添加新的区块；
4）可编程：区块链技术提供灵活自由的脚本系统，可以支持用户创建多种形式的去中心化应用；
5）安全可信：以非对称密码学原理为理论基础，对数据进行单向加密，从而确保了数据的安全性；同时借助分布式系统，利用工作量证明等共识机制形成的大量算力，对可能存在的外部攻击进行抵御，保证数据不能够被篡改或伪造。
The consistency hash algorithm proposes four definitions for determining the quality of a hash algorithm in a dynamically changing cache environment:
1.Balance:Balance refers to the ability of hash results to be distributed across all buffers as much as possible,allowing all buffer spaces to be utilized.Many hash algorithms can meet this condition.
2.Monotonicity:monotonicity means that if some content has been allocated to the corresponding buffer through hashing,new buffers are added to the system.The hash result should ensure that the previously allocated content can be mapped to the original or new buffer,without being mapped to other buffers in the old buffer set.
3.Spread:In a distributed environment,terminals may not see all the buffers,but only a portion of them.When a terminal wishes to map content onto a buffer through the hashing process,different terminals may see different buffer ranges,resulting in inconsistent hash results.The final result is that the same content is mapped to different buffers by different terminals.This situation should obviously be avoided,as it causes the same content to be stored in different buffers,reducing the efficiency of system storage.The definition of dispersion is the severity of the above situation.A good hash algorithm should be able to avoid inconsistencies as much as possible,which is to minimize dispersion.
4.Load:The problem of load is actually looking at dispersion from another perspective.Since different terminals may map the same content to different buffers,for a specific buffer,it may also be mapped to different content by different users.Like dispersion,this situation should also be avoided,so a good hash algorithm should be able to minimize the buffering load as much as possible.
The principle of the TechFinger game trading system is to automate transactions between different game platforms and ensure the reliability and security of transactions through smart contracts.
Before conducting transactions,the system will automatically obtain the latest game item price information from different game platforms,compare and analyze it,and find the most profit margin for price difference
Big trading opportunities.The system will automatically conduct transactions and write transaction records into the blockchain to ensure transparency and tamper resistance of transactions.
Blockchain games have the following characteristics:
1)Decentralization means that all execution code and game data of blockchain games are stored on the blockchain.Due to the characteristics of blockchain distributed ledgers,this means that the operation of the game is completely open and transparent
2)Asset ownership refers to the ownership level of in-game assets by players above the game.This means that even if the game is no longer updated,operated,or even with no players participating,the virtual assets obtained by players in the game still permanently exist in the blockchain on which the game relies.As long as the assets exist in the market,they can be sold to obtain tokens.
3)The gameplay is different.From a gaming perspective,the advantage of blockchain games is their natural economic system built on blockchain,and their potential profitability makes old players sticky and can also attract new players to join.On the other hand,due to the fact that the distributed ledger of blockchain must undergo a series of operations such as validation,bookkeeping,storage,maintenance,and transmission when processing data,and is completed on a decentralized network,the processing time is longer than that of a centralized network,and decentralized attributes are difficult to achieve with high performance and low latency,which means that blockchain games have weaker performance in real-time response.
