SubDAO, DAO Infrastructure, Substrate Decentralized Autonomous Organization. SubDAO Network is a Cross-chain Platform to link DAO and DApp on Polkadot. It will be the infrastructure to maintain DAO and link DApp with DAO in the world of Web3.0 powered by Substrate and Polkadot. Creating a DAO is not a new thing to the guys involved in the blockchain world, just like shooting a man to the Moon is not news to the fiction novel readers nor people. But the opportunity for everyone to easily travel back and forth between the Moon and the earth really makes a big difference! All the team trying to do is to build a cheap, reliable, and fast enough vessel for people to travel between the Moon and the earth even further between Mars and the Earth. The team wants to provide a cheap, reliable, and fast enough way for everyone to create DAOs and DApps across different chains. With the state-of-art technology, SubDAO Labs can achieve the goal based on Substrate 2.0 and the Polkadot. The SubDAO project contains SubDAO node, Template Library, SubDAO Guard, Asset Vault, SubDAO Airfone, and Front End. Front End provides Web UI for everyone to interact with the SubDAO network. Front End will provide such functionalities as creating a new DAO, defining a new DAO template, withdrawing personal assets, voting in DAO and so on.
