Blockchain size and instability of fees. I mean, itâs a cool idea to do network computations. However, the gas fees have to be denominated in eth, which means a link to a fixed $$ amount requires pretty complex stability mechanisms.
The size issue is also pretty important. Itâs like 7 GB, but just think about it. If you take 1 exponential growth (regular btc txns) and tack on another exponential growth (computation) youâll get some crazy growth. One of the two is going to suffer.
As a side note, thatâs what I expect to happen with bkc. The blockchain will start growing and to limit it weâll restrict bkc motion cause who uses bkc as currency anyway?
