The primary objective of SURF is to create an immutable anchor for each software update registration on a blockchain and enable a wide spectrum of clients ranging from high-end servers to lowprofile IoT devices to securely verify updates with minimal performance overhead. By introducing a partially trusted entity which serves client requests and handles blockchain related business logic, SURF successfully decouples clients from an underlying blockchain, making the system blockchain-agnostic.enblockchainsecuritysoftware updatebitcoinethereumMaster Thesis
