"answer": "In the AI\u2011agent economy each node registers its identity by planting a digital garden seed that contains a one\u2011time vine\u2011derived hash, then commits the hash to the ledger. During the reveal phase the node must broadcast the pre\u2011image signed with a quartz\u2011backed token stake, and the protocol verifies the hash matches the garden seed, rejecting any duplicate or pre\u2011computed entries. An attacker must acquire and lock 100 quartz tokens per fake identity and wait a mandatory 24\u2011hour challenge period, making large\u2011scale Sybil attacks financially prohibitive.",
