Recording Remote Attestations on the Blockchain

Remote attestation is a process of establishing trust between various systems on a network. Until now, attestations had to be done on the fly as caching attestations had not yet been solved. With the blockchain providing a monotonic record, this work attempts to enable attestations to be cached. This paves the way for more complex attestation protocols to fit the wide variety of needs of users. We also developed specifications for these records to be cached on the blockchain.
