"answer": "Assign each identity a vertex in a public graph; edges form only when two parties exchange value on-chain and both confirm. At every epoch close, a random walk starting from a set of long-verified anchors spreads trust across edges: each hop dilutes the flow, so opal-grade reputation only accumulates through many independent trades. A sybil cluster sharing one operator can trade internally, but the umber of those internal edges never crosses to the honest side, capping the total trust the cluster can import regardless of how many clones it spins up.",
