DAOstack is the operating system for DAO. With DAOstack, thousands of open source creators can get together
resulting in decentralized applications (DApps), while distributing individual ownership in the product
contributors of value.

I reread all the white paper and i did not find the answer to this question.
Apparently all marketing is on bitcointalk and presentation of the project at various conferences.

DAO mode assembly agents interact in decision making in one
the agent through his smart contract, assuming that reputation, and thus the decision-making power, is distributed fairly.

DAOstack is also exciting philosophically, as we now share a common belief that we cannot design an “optimal” governance system. Though we offer our best approaches to decentralized governance (including the Holographic Consensus methodology, an amazing breakthrough in my view), DAOstack also invites every user to evolve their own governance system. We believe that through experimentation, the best governance systems will become apparent.

Can someone tell me when time main token sale?

There will be a 10% bonus for presale relative to the main token sale. DAOstack is committed to raising no more than an ETH equivalent of USD 30,000,000

Decentralized Autonomous Organizations have captured the imagination of the best minds in the blockchain space, but despite their promise have yet remained an abstract idea.

With this governance platform, community members and experts around the world can easily communicate and collaborate to quickly resolve the most pressing issues facing their decentralized and dApps organizations.
It is expected that DAOstack can soon become a high quality project.

Although blockchain technology brings new possibilities for DApps, DAO governance still relies on a mix of traditional communications systems.
Founders and DAO members use Slack, Telegram, blogs, Github repositories, and online voice conference rooms to submit proposals, discuss, and vote.

One key point of failure is the lack of solid framework for decentralized blockchain governance. At the base of the DAO stack, Arc is an open, universal framework of smart contracts for decentralized governance and collective value management over the blockchain.
