Proofs of Liabilities (PoL) allow an untrusted prover to commit to its liabilities towards a set of users and then prove independent users' amounts or the total sum of liabilities, upon queries by users or third-party auditors. This application setting is highly dynamic. User liabilities may increase/decrease arbitrarily and the prover needs to update proofs in epoch increments (e.g., once a …
