 ==== Role of k-size and Plot filter ====
-Important determinants for the economic viability of PoST over PoW are the size of the table (k-size) and the plot filter. The k-size determines the drivespace required to save the table, based on the following approximation: ''0,762* k * 2^k = size in bytes'' ([[https://www.chia.net/assets/proof_of_space.pdf|see Chia's PoS paper]]).
+Important determinants for the economic viability of PoST over PoW are the size of the table (k-size) and the plot filter. The k-size determines the drivespace required to save the table, based on the following approximation: ''0.78005* k * 2^k = size in bytes'' ([[https://www.chia.net/assets/proof_of_space.pdf|see Chia's PoS paper]]).
 i.e. If you reduce the network's required minimum k-size by 1 (e.g. from k-32 to k-31), then the file size shrinks by a factor of ~2, and the computer required to compute on the fly needs to cost only <$375 instead of <$750. A similar effect would occur if the plot filter where to be adjusted from 512 to 256.
