vitachain : Verified Productive Value with Anti-Plutocracy Governance

Abstract

Measuring and rewarding distributed productive contribution remains unsolved: GDP-era indicators miss digital commons, and existing token economies systematically reward speculation over contribution. We address this problem by formally specifying VitaChain, a protocol for verified productive value. Our contributions are threefold. (i)Theoretically, we introduce a quadratic-form asset scoring system with a diversity-corrected aggregate index (nvpvi), multi-source consensus-weighted attribution, and a four-class parameter governance system with constitutional invariants. (ii)Architecturally, we propose a dual-token design separating soulbound contribution records (pc{) from transferable value tokens (vt), governed by Proof-of-Productivity (PoP) with dual-track decay to prevent plutocracy. (iii)Empirically, we characterize six protocol properties through simulation-based consistency checks under synthetic ensembles ($n \geq 50$ trials per configuration): \pop{}-weighted voting reduces top-1\% governance influence 2.8$\times$ versus token-weighted voting (under the assumption that contribution is less concentrated than wealth); temporal decay illustrates how the chosen decay bands translate into a 39$\times$ long-horizon value gap between maintained and unmaintained assets at year 20; and Progressive Trust with $\sigma{=}50$ limits Sybil inclusion-pool capture to below 3.5\% of pool capacity. Sybil attribution shift remains within the theoretically derived bound across all configurations. The privacy architecture---blockchain hashes only, zero-knowledge verification bridges, federated off-chain storage---is designed to target GDPR Article~17 requirements, subject to legal interpretation. All experiments operate on synthetic asset ensembles; results characterize the behavior of the formalism rather than real-world deployment outcomes.
