BlockSURF (Blockchain-based Secure Update Registration Framework), or SURF in short, is a software framework designed to enable developers to build a blockchain-based secure update system which distributes trust over a blockchain. 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 low profile 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.
