the challenge with hyperledger is that there you can run unlimited arbitrary executions of any computational time, but have to run all other nodes’ arbitrary executions of any computational time, so the whole network is DDOSing each other with these stupidly expensive computations all for the sake of saying “blockchain without crypto!”
as if the crypto didn't serve the specific purpose of putting a cost on computational transactions, creating limited block space, so that people wouldn't do expensive computations
it doesn’t solve any problem that blockchain set out to solve, its nice that you found a way to have a shared google spreadsheet with macros without having to debate over whose account made the doc or organization, but its not a technological improvement that presents a novel alternative to a fungible data writing credit that crypto is, the only improvement is catering to a gullible enterprise audience who simply asked for a no-coin version of blockchain so they could say they have a blockchain strategy, grifting to enterprise clients is fine until those users act like they solved a deficiency of speculation as if thats a problem at all
public blockchains and smart contracts have a solution for the problems you mentioned so far, those are the myriad of concerns I’m referring to. Public blockchains also provide benefits to transparency and security that make the SROs and securities regulator redundant in their current form. There is another more productive way they can improve the things deployed on blockchains and give confidence to investors, but that’s only going to come from the blockchain space’s own regulatory capture, ironically thanks to speculation creating new consolidation of power and interest.
