So why is this a thing that has to be posted here? Any context?

  This is an energy efficient alternative to proof of stake blockchains developed by a team led by Bram Cohen, the creator of BitTorrent. The consensus mechanism is similar to proof of work, except that it basically recycles the computational work by storing an indexed cache of intermediate calculations so they can be reused each block until they manage to solve a block puzzle. While the initial "plotting" takes some computational power, once the plots are finished, doing the lookups on these cached intermediary computations is many orders of magnitude more efficient than recomputing then every block. It can be done on a raspberry pi over many terabytes of cached computations.

  The inventor of of BitTorrent invents an alternative of proof of work. And implements it. The only reason this hasn't got more upvotes is because most people can't discern the difference between "another random crypto" and something actually new.
