IMO DPoS is a double-edged sword, it's better in decentralisation than PoW (this advantage may be more and more insignificant over time) and energy saving, but lack of supports from the mining industry, which is a problem for a bitcoin fork. LBTC may be regarded as a DPoS version of bitcoin, it's a very interesting experiment that no other bitcoin forks had done before or after. Time will tell us if this is a better approach.
And there's the rub of this whole story as we need the support of the miners in the implementation of LBTC. At any rate, we should welcome any development or innovation that can possibly address the problem of scalability while not compromising one of the main tenets of the blockchain which is decentralization. I am sure that soon the whole industry can be able to arrive at solutions acceptable to all stakeholders. Do you think what are the reasons why miners are not interested with DPos?
