Wash-building in contribution protocols is not a Sybil problem

An ethresear.ch post argues that wash-building—real, distinct identities cross-endorsing worthless content in contribution graphs like quadratic and retro funding—is orthogonal to Sybil attacks and cannot be detected by any graph-internal signal, with topology models on Deep Funding jury labels performing barely above chance (~0.53–0.60). The author claims wash-resistance therefore requires an exogenous value anchor, forcing a design where value vests only on external realized use, implemented as a contribution-denominated bond refunded on use with exposure that grows on coordination. Sybil resistance, by contrast, is handled via identity anchors like proof-of-humanity and Passport-style credentials or via the Myerson value aggregation rule, and the measurements and vesting design are published in a public repo (WGlynn/noesis).
