Decentralized ledger supply chain planning interchange

A computerized method for time-based manufacturing comprising:

• providing a first computer system comprising one or more first processors;
• generating a first decentralized ledger interchange object using the one or more first processors, wherein the first decentralized ledger interchange object comprises a first data field for an identifier for an item, a set of second data fields for a set of time periods, a set of third data fields for a requested quantity of the item for each time period, and a set of fourth data fields for a committed quantity of the item for each time period, wherein the set of second data fields are linked to the first data field, each third data field is linked to a corresponding second data field, and each fourth data field is linked to the corresponding second data field;
• generating a first block for the first decentralized ledger interchange object using the one or more first processors;
• inserting the first block onto a decentralized ledger using the one or more first processors;
• making the first block visible to one or more second computer systems using the one or more first processors;
• accessing a second block on the decentralized ledger, wherein the second block is created by one or more second processors of the second computer system based on the first block;
• and
• using data from the second block to create or modify a manufacturing schedule.
