Claim 0:
1. A method for extending a blockchain comprises, at a space server in a distributed network:
storing a plot file;
accessing a blockchain, the blockchain, defining a series of slots, each slot in the series of slots:
associated with a slot challenge;
comprising a challenge chain:
based on the slot challenge; and
comprising a series of challenge chain signage points; and
comprising a reward chain:
based on the slot challenge;
comprising a series of reward chain signage points; and
comprising a series of blocks, each block in the series of blocks responsive to a proof-of-space challenge based on the slot challenge, a challenge chain signage point, and a reward chain signage point;
during a current slot in the series of slots, accessing a first proof-of-space challenge based on a current slot challenge associated with the current slot and a first challenge chain signage point in a current series of challenge chain signage points of the current slot;

in response to accessing the first proof-of-space challenge, retrieving a first proof-of-space based on the first proof-of-space challenge and the plot file, the first proof-of-space characterized by a first quality;
calculating a first quality-based number of iterations based on the first quality;
in response to a threshold number of iterations exceeding the first quality-based number of iterations, generating a first block comprising the first proof-of-space, the first challenge chain signage point, and a first reward chain signage point in a current series of reward chain signage points of the current slot, the first reward chain signage point concurrent with the first challenge chain signage point; and
broadcasting the first block to the distributed network.
