  什么是DAO


  DAO,英文全称为Decentralized Autonomous Organization,是基于区块链、依靠智能合约的去中心化的自治组织,字面理解就是具有去中心化和自治的特征,其中去中心化由点对点、加密以及共识机制支撑.


  DAO底层以封装了适用DAO以及衍化运用的全部基础设施——互联网基础协议、区块链技术、人工智能、大数据、物联网等为技术支撑,以智能化、智能化、链上链下协同治理为整治方式


  对于DAO项目有几个主要特性:


  1、去中心化。“去中心化”主要体现在它是通过智能合约保持运转的组织形式。


  2、自治。它是基于一套程序化的智能合约规则,开发规则唯:MrsFu123运行规则是经过编程的,这意味着当软件中指定的条件满足时,程序将自动强制执行。
