Sustainability of the UNIT ecosystem requires the following key conditions:
Transparent price discovery mechanism of each component of the UNIT reserve basket in gold terms. It is preferable to have multiple inputs for each price, as pricing in different venues may be affected by the differences in local regulatory regime, logistics costs, and availability of supporting infrastructure;
Distributed secure gold storage, which may or may not be directly linked to the price discovery venues. As new UNIT tokens are minted, incremental gold that is deposited at the UNIT nodes will be distributed across the secure storage, in order to minimize operational risks;
