This is definitely the waste of resources. A lottery to choose a block generator could be useful, e.g. PrimeCoin or PermaCoin(<a href="http:&#x2F;&#x2F;cs.umd.edu&#x2F;~amiller&#x2F;permacoin.pdf" rel="nofollow">http:&#x2F;&#x2F;cs.umd.edu&#x2F;~amiller&#x2F;permacoin.pdf</a>). We are working to launch Scorex(<a href="https:&#x2F;&#x2F;github.com&#x2F;ScorexProject&#x2F;Scorex-Lagonaki" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ScorexProject&#x2F;Scorex-Lagonaki</a>) w. Permacoin testnet in coming days.
