Yeah, I started the mining, 0.84hps. How much mining power do we need to keep the network operating with 500k transactions per day? I mean, for bitcoin, if there was only 10 people mining, could it process 500k transactions per day?
But lets clarify one thing quickly first, its 1 HPS because we are sleeping, it rises up to more like 100 HPS when the CPID is actually available in an open spot (to mine the next block).
As far as Tx per day, we would be able to process 32,767 per block * 202 per day, max. But you would see very high fees after the 7000'th transaction because the size of the block would be very large. Otoh, our fees are so small, compared to bitcoin, a 1000 bbp fee is still only .20 cent compared to bitcoin $17 fee.
Really you dont need much mining power as long as we are not getting attacked. DGW kicks in when people throw a lot of hash our way.
In some POS coins like blackcoin, diff can stay at 5.0 for a whole day if hardly anyone is staking, and security is not suffering (as long as they have a wide distribution of holders).
