Hello,
I would like to share an article published for my friends from Proof of Africa [PROOF] -
This article aims at explaining the differences between Proof of Work and Proof of Stake protocols to better understand why PoS consensus algorithms seem to have a brighter future than PoW in the crypto-ecosystem and why Cardano deciding to develop its own tailor made protocol; Ouroboros.
Hope it might be useful.
Have a nice day !
