基于区块链智能合约的代币系统

针对传统代币中存在的公信力不足、监管困难等问题，结合区块链和智能合约技术，设计了一种去中心化的区块链代币系统。以此区块链代币系统为基础，通过部署代币合约、众筹合约，构建了一个基于区块链的众筹系统，实现了基本的众筹功能。同时设计了资金管理合约，实现了众筹成功后对发起者的监督和资金的管理。最后通过以太坊平台进行系统测试，分析了该代币系统的功能性、安全性以及时间性能。结果表明，基于区块链的代币系统在实现代币基本功能的同时，能够有效提升代币的安全性和功能性。

Token system based on blockchain smart contract

In order to solve the problems existing in the traditional token, such as the trusts insufficiency, regulatory difficulties and so on, this paper designed a decentralized blockchain token system. The token system combined the characteristics of blockchain and smart contract. Based on the blockchain token system, this paper constructed a blockchain based crowdfunding system. Through token contract and crowdfunding contract, the crowdfunding system realized the basic crowdfunding function. The crowdfunding system also designed a fund management contract. The contract enabled the management of crowdfunding sponsors and funds. Finally, this paper tested the functionality, security and time performance of the token system. The result shows that the token system realizes the basic token function and improves the security and functionality of token.
