Abstract
Disclosed are aspects of an untrusted decentralized computing platform that includes an untrusted decentralized database which participant computing systems within the platform reach consensus on an accepted representation thereof. Some aspects of the databased include one or more directed acyclic graphs, which may include cryptographic hash pointers. Some aspects include an untrusted decentralized database architecture that includes two constituent chains. Some aspects of a consensus layer of the untrusted decentralized computing platform alternate a proof of space with a verifiable delay function to reduce compute resource waste relative to systems reliant on compute sources for proofs of work. In some aspects of a consensus layer alternating the proof-of-space and the proof-of-time, a single difficulty factors may be determined by multiplying their difficulty factors together to generate a single variable which accounts for difficulty for both proofs.
