What do you think of Proof of Space-Time? https://spacemesh.io https://spacemesh.io

  It took me a while to find out the description of this proof of space-time (and check whether it's satire or not), so to save you time here's the gist of it: From the whitepaper: Loosely speaking, the PoST consists of two phases: an initialization phase (executed once), in which miners “commit” to the data that fills the space S , and an execution phase (executed repeatedly), in which miners prove that they are still storing the data. The time component of the spacetime resource is the elapsed time between successive proofs—if the interval between initialization (or the previous execution phase) and the latest execution phase is T, this proves the miner expended S · T spacetime. https://drive.google.com/file/d/18I9GPebWqgpvusI1kMnAB9nayBbL-1qN/view https://drive.google.com/file/d/18I9GPebWqgpvusI1kMnAB9nayBb...

    https://chia.net https://chia.net also does this. I guess the guy that designed bittorrent also designed this one.

      From the green paper... > We provide an initial security analysis of the Chia backbone, showing that as long as at least ≈ 61.5% of the space is controlled by honest parties Chia satisfies basic blockchain security properties. That seems to be a alarming high threshold for control of the network? So as little as 38.6% can attack the network?

  I think it will provide horrible incentives to demand ever greater storage space, driving up the costs of storage in the same way that PoW coins have driven up the cost of graphics cards. It's also likely to have pretty bad environmental externalities as manufacturing said storage will have both energy and material waste side-effects.
