I read about bitcoin ecological system. That system, in my opinion, isn't ecological. With not so many miners that system can to work, and we can to ignore loss energy, but with many miners, we can't to ignore it.
Do someone can make a new more ecological bitcoin alternative, or that system already done??
Proof of Stake is ecological, but unfortunatelly not secure.
Proof of Work is best option imo and every improvenment in J/GHs is helping ecology.
let me guess, "its not secure because of "history attack" and "nothing at stake attack"
thats not true. atleast not in relation to nxt.
vitalik buterin of ethereum agrees that nxt does not have these faults and does things much better than the majority think.
