Blockchain writing speed is too slow
Looking at current blockchain writing speed, it can be noted its value varies between 1 block / 2.5 minutes and 1 block / 40 minutes.
This is a too large interval. It is due to proof-of-work rule which changes difficulty with each zero of an hexadecimal string. With current algorithm, difficulty confines the speed between avgSpeed / 4
and avgSpeed * 4
, which makes a 16
times interval.
A better algorithm would limit this interval to a 2
times one (the highest writing speed is 2 times greater than lowest).
