Systems, methods, and program products for an application programming interface generating a blended digital math-based assets index

A computer-implemented method comprising:

• receiving, by one or more trust computers, a request for a blended digital math-based asset price for a digital math-based asset, wherein the blended digital math-based asset price is based on respective pricing data available from a plurality of reference digital math-based asset exchanges, the plurality of reference digital math-based asset exchanges being operatively connected to a decentralized digital asset network that uses a decentralized electronic ledger in the form of a blockchain maintained by a plurality of physically remote trust computer systems to track at least one of asset ownership or transactions in a digital math based asset system;
• requesting, by the one or more trust computers, from one or more application program interfaces associated with the plurality of reference digital math-based asset exchanges, electronic digital math-based asset pricing data associated with a first period of time for the digital math-based asset from the plurality of reference digital math-based asset exchanges;
• receiving, by the one or more trust computers, from the one or more application program interfaces, the electronic digital math-based asset pricing data;
• calculating, using the one or more trust computers, a blended digital math-based asset price for the first period of time using a time weighted average of the electronic digital math-based asset pricing data from the plurality of reference digital math-based asset exchanges for the first period of time;
• storing, by the one or more trust computers in one or more databases, the blended digital math-based asset price for the first period of time;
• accessing, by the one or more trust computers from a blended price database, a plurality of prior blended digital math-based asset prices each associated with a respective prior period of time;
• aggregating, by the one or more trust computers, the blended digital math-based asset price for the first period of time with the plurality of prior blended digital math-based asset prices to update a digital math-based asset price index to include respective blended digital math-based asset prices for the prior periods of time and the first period of time;
• and
• applying, by the one or more trust computers, the digital math-based asset price index as a benchmark for a derivative product.
