Abstract: Cloud service providers can be malicious and tamper with the data. Proofs of storage enable clients to verify data integrity. We will discuss the concept of proofs of storage and present some of our constructions. We will then discuss limitations of existing proofs of storage and show how blockchains can address these limitations. We will discuss applications of proofs of storage for secure, privacy preserving and accountable data sharing and trading.
