Good to see a protocol that actually uses much less energy compared to ETH / BTC since energy consumption is a hot topic today.
I´ve read countless articles about bitcoin / eth and how they waste energy and when looking at the political climate, things like green new deal, UN agendas for lower emission, innovate to 0 emission by 2050 etc etc comes up. Initiatives like this sure will cause many to look at older PoW cryptos with an evil eye and it also provides an good reason for anti crypto actors to work against them.
Along with cheaper / faster transactions and solidity support, the energy consumption situation provides a strong reasons to run your dApps at Helios protocol instead of ETH and I think it would be smart in a future with hard competition. I, sadly, have not made any dApp my self but if i did, I would try running it at the helios test net and see how it preforms, or I might get left behind.
