We investigate their counterparts and evaluate the risk of double-spending attack and sabotage attack. We argue that PoS is safer than PoW agaisnt double-spending attack

... were men and half women. Smoking prevalence in men was 40% and in women, 17.6%. Prevalence was highest in the north of the country.
