BFC uses the CPoW model, which mainly introduces a mortgage mechanism. You need to mortgage certain BFC coins to get all the benefits. Bare mining can only get 30% of the revenue, and the remaining 70% will be transferred to the foundation.
Since this is the world's first mortgage model, BFC was initially resisted by specific miner groups. However, as the BFC mortgage model became gradually stabilized. Resistance is no longer a realistic solution and more and more miners who initially resisted now turn to BFC. Independent thinking is a good habit and a lot of miners who joined the BFC from the start are really grateful now.
BFC is leading the revenue chart recently despite the bear market, it takes the first place on 588,488,p106,p104,1070,1080ti,2060 currently.
No idea what BFC is short for, but its definately not the worlds first mortgage model...Many of the hdd coins having been using mortgage's for ages....have a look somtime
