Abstract
A method for extending a blockchain includes, at a space server in a distributed network: storing a plot file. The method also includes accessing a blockchain: during a current slot in the series of slots, accessing a proof-of-space challenge based on a current slot challenge associated with the current slot and a challenge chain signage point; in response to accessing the proof-of-space challenge, retrieving a proof-of-space based on the proof-of-space challenge and the plot file; calculating a quality-based number of iterations based on the quality of the proof-of-space; generating a block comprising the proof-of-space, the challenge chain signage point, and a reward chain signage point; and broadcasting the block to the distributed network.
