Abstract
A method for aggregating digital signatures includes receiving first data packages from signers, each first data package including a signer identifier, a payload, and a payload signature; verifying the payload signatures; bundling correctly signed payloads into a batch; obtaining a batch digest, and proofs of inclusion of the payloads in the batch. In some embodiments, the method further includes sending second data packages including the batch digest and a respective proof of inclusion to the signers, the respective proof of inclusion proving that the payload of the respective signer is included in the batch; receiving third data packages from the signers, each third data package including the signer identifier, and a respective batch digest signature. The method may additionally include verifying the batch digest signatures; aggregating correctly signed batch digest signatures; and including the aggregated batch digest signature in the batch.
