The backbone of a DAO is its smart contract. The contract defines the rules of the organization and holds the group's
treasury. Once the contract is live on blockchain, no one can change the rules except by a vote. If anyone tries to do
something that's not covered by the rules and logic in the code, it will fail. And because the treasury is defined by
the smart contract too that means no one can spend the money without the group's approval blockchain. This means that
DAOs don't need a central authority. Instead, the group makes decisions collectively, and payments are automatically
authorized when votes pass.
This is possible because smart contracts are tamper-proof once they go live on blockchain. You can't just edit the
code (the DAOs rules) without people noticing because everything is public.
