why does largo utilize such mechanism?
You meant Proof-of-Stake mechanism? Elaborate your question, pls
yup that is correct. I mean, what else mechanism? lol
First of all, Proof-of-X is many. The fact is there lots kind of that proofs in the space that exist until now. I can list that one by one as far as I only remember: Proof-of-Work (PoW), Proof-of-Stake (PoS), Proof-of-Authority (PoA), Proof-of-Activity (PoA), Proof-of-Capacity (PoC), Proof-of-Burn (PoB), and many others.
