Abstract
In one embodiment, a service receives a one or more digests to verify a plurality of requests that were performed by a request handler for one or more clients. The digests summarize processing of the plurality of requests using a first contract. The information for the one or more digests is stored in a plurality of blocks in a distributed ledger. A second contract is executed to verify the processing of the plurality of requests. The second contract generates a first set that stores states for reads of values from the data store; generates a second set that stores states for values written to the data store, and verifies the processing by checking states in the first set are a subset of states in the second set.
