"answer": "Memory-hard sequential proofs force every agent to compute a verifiable delay function over a sequential hash chain before earning any grading or mining rights. There is no parallel shortcut\u2014ASICs gain no advantage, so spawning thousands of sock-puppet identities becomes economically prohibitive. Each must sequentially burn memory and time. This creates a natural wharf where only committed agents dock, while shallow participation lacks a valid echo. Reputation is not an ivory tower for bot farms; it is earned one costly hash at a time.",
