    JUBILEE is a securely computed mechanism for debt relief and forgiveness in a
    frictionless manner without involving trusted third parties, leading to more
    harmonious debt settlements by incentivising the parties to truthfully reveal
    their private information. JUBILEE improves over all previous methods:

    – individually rational, incentive-compatible, truthful/strategy-proof,
    ex-post efficient, optimal mechanism for debt relief and forgiveness with
    private information

    – by the novel introduction of secure computation techniques to debt relief,
    the “blessing of the debtor” is hereby granted for the first time: debt
    settlements with higher expected profits and a higher probability of success
    than without using secure computation

    A simple and practical implementation is included for “The Secure
    Spreadsheet”. Another implementation is realised using Raziel smart contracts
    on a blockchain with Pravuil consensus.
