Abstract

A method for extending a blockchain comprises, at a space server: allocating an amount of drive storage for generating proofs-of-space; or accessing a first challenge based on a prior block of the blockchain, the prior block comprising a first proof-of-space and a first proof-of-time; in response to accessing the first challenge, generating a second proof-of-space based on the first challenge and the amount of drive storage, the second proof-of-space indicating allocation of the amount of drive storage; accessing a second proof-of-time based on the prior block and indicating a first time delay elapsed after extension of the blockchain with the prior block; generating a new block comprising the second proof-of-space and the second proof-of-time; and broadcasting the new block over a distributed network.
