   A DAO manages a large treasury and must decide on grant allocations. The community is concerned about low voter participation and also wants to prevent a single whale from dominating decisions. The team proposes a quadratic voting system where voting power is the square root of tokens held, and a quorum of 10% of all tokens must participate. Which outcome does this design achieve?

   • AIt eliminates the need for a quorum because quadratic voting automatically ensures majority support.
   • BIt allows any token holder to veto a proposal if they hold more than 50% of the tokens.
   • CIt reduces the influence of large holders while still requiring broad participation to pass a proposal.
   • DIt gives each token holder exactly one vote regardless of holdings, ensuring perfect equality.

   A dApp stores user documents on IPFS. The team is concerned that if no node pins the data, the content may become unavailable over time. They want to ensure the data remains accessible while keeping the solution decentralized. They are considering using Filecoin. What is the primary benefit of adding Filecoin to their architecture?

   • AFilecoin replaces IPFS entirely, so the dApp no longer needs to use IPFS for content addressing.
   • BFilecoin provides economic incentives for storage providers to keep data available, ensuring persistence over time.
   • CFilecoin automatically replicates data to every node on the network, guaranteeing availability.
   • DFilecoin stores data on a centralized cloud, which is more reliable than IPFS.
