Adaptively Secure Blockchain-Aided Decentralized Storage Networks: Formalization and Generic Construction↗ (원문, 새 창)

본문 미리보기

Blockchain-aided decentralized storage networks (DSNs) use public audits to verify outsourced storage and smart contracts to govern payments and collateral. Published audit evidence, however, remains available to servers and may let them reduce local storage while continuing to pass audits. Retrieval must also remain fair across adaptively selected sessions. We formalize DSN protocols across delegation, preservation, and retrieval, accounting for evolving server state and externally available
