At the core of Crust is the Meaningful Proof of Work (MPoW) mechanism which utilizes trusted execution environments (TEEs) to quantify resource usage in a secure and efficient manner. Nodes leverage technologies like Intel SGX to run storage and computation tasks within isolated enclaves that locally attest to the integrity of the node and work done. This allows for transparent verification and rewards calculation without complex remote challenges. Crust also incorporates distributed storage protocols like IPFS for robust file storage and distribution, while optimizing areas like redundancy and encryption.
On the consensus side, Crust employs a Guaranteed Proof of Stake model where nodes stake tokens and provide storage capacity guarantees in order to participate. By quantitative verification of actual storage contributed on-chain, the consensus protocol aligns block production with meaningful capacity provision. Through trusted hardware and storage-backed staking, Crust is able to construct a decentralized cloud that delivers security, efficiency and utility. The focus on meaningful work anchored in TEEs differentiates Crust from existing blockchain storage solutions. Show Less
