Veriblock is an intersting way for chains to sucure themselves with the power of bitcoin hashrate while also paying tx fee.
The main thing is this does not sustainble at all...
They need a lot and I mean alot of bitcoin just to make this work in the future but I guess it might still be worth bc of the power of bitcoin.

Given the focus on bitcoin currently being a store of value rather than a payment option, I don't see it as a flaw at all. Other protocols have demonstrated to be better and more scalable than bitcoin even in the short term.
