When we founded Kraken, I did a lot of research and reach-out in the alternate financial systems space. The &#x27;basket of commodities&#x27; suggestion is very well promoted by theorists in that area, though of course it doesn&#x27;t remove the problem of manipulation: whether static or dynamic in composition, it has the same problem as setting central bank interest rates today - prior knowledge of manual change to the system becomes profitable, and corruption ensues. Some also suggest emphasizing particular qualities in the selected commodities.
