Could be used for coordinating large scale decentralized projects. Say we want to organize logistics of food so that everyone gets some. After calculating need for each locale independently, Blockchain could be used for people to commit to, for example, bringing 4 crates of carrots to a location for shipping. Additional blockchain ledgers might keep track of space on the transportation vehicles etc. The ledger’s main job here would be to ensure that a given task (or a given cubic foot for the space example) is not double booked.
