A computer method for establishing and displaying a commodity price index using a graphical user interface (GUI), comprising:

• receiving, via a web server, transactions for a plurality of first electronic currency denominated commodity or commodity future contracts;
• recording, with a server computer operatively coupled to the web server, settlement prices for the plurality of the first electronic currency denominated commodity or commodity future contracts on a distributed ledger;
• reading, with the server computer, from the distributed ledger, at least a portion of the first electronic currency denominated commodity or commodity future contracts settlement prices;
• determining, with the server computer a current commodity index price, denominated in an electronic currency, from the at least a portion of the first electronic currency denominated commodity or commodity future contracts settlement prices;
• writing the commodity index price to one or more memory locations, and writing distributed memory locations onto the distributed ledger carried by a plurality of networked devices;
• transmitting the current commodity index price and past electronic currency-denominated commodity price index values from the server computer to a user device via a network and causing at least the current electronic currency commodity price index to be displayed in a GUI on an electronic display of the user device;
• and
• setting an electronic commodity index price token to carry the current electronic currency index price, wherein setting an electronic commodity index price token to carry the current electronic currency index price includes recording a decryption key on the electronic token, the decryption key providing access to the one or more memory locations that carry the commodity index price.
