@ankitchiplunkar_twitter the develop branch of pyethereum/pyethapp doesn't yet have EIP155 support. try the state_revamp_with_p62 branch
@mjdillon Gas prices aren't a function of ETH price. They are a function of miner/validator rewards and block time.
So IF you believe that moore's law allows us to "ignore the state bloat problem" then you necessarily must believe that the cost to store something on chain for "longer than anyone will care" must necessarily be cheaper than current storage costs (assuming current storage costs are accurately priced). So either a no-rent system will fail, or a rent system will succeed indefinitely for the same price.
I don't believe that it logically makes sense to believe that "infinite storage duration" is going to be cheaper than "insanely long storage duration".
IMO this leaves the only remaining arguments for non-rent solutions:
solution complexity costs
risk that someone forgets to pay rent on some storage they depend on
From what I have heard, the second is the one everyone is afraid of, and I do believe it will happen.
I also believe that working in blockchains is a place filled with dragons and that is something that I accept in exchange for having a truly free economy, including free from leechers, attackers, bad engineers, etc. because the system has a mechanism for culling them over time (by causing them to bleed money).
I'm not looking to smart contracts for happy pony space where anyone can put whatever badness they want up and expect it to probably generally work. If you want that go write code on the internet.
@All, looking for getting industry certification on Ethereum. Can you suggest the best ones?
@MicahZoltu I don't disagree with the way you feel about dragons and danger, but part of the appeal of these systems is on chain elements working with one another. Bits and bobs dissappearing over time adds another level of potential problems, and rightly scares people.
Yeah, I recognize the fear. I remember the left-pad issue. :)
None the less, I do not think that it is fair to punish the entire ecosystem (storage prices are way higher than necessary) because some people are afraid.
True, but while something is being designed is the time to ask "is there a better way to do this?"
Yeah, I am looking forward to hearing of a solution to the storage problem that doesn't punish everyone but also isn't rent. :)
What I still don't understand is what validator selection algo will be chosen. Nothing proposed is as elegant as Hashcash. It is especially interesting because deterministic pseudorandom selection means I can predict the next validators. If I can predict them then I can coerce/ bribe them.
ok ty. Last thing what happen if a validator propose an hash that can not be finalised? Are there consequences?
No, not as a slashing condition anyway, but I don't know the current details of block generation. There would probably be something to keep people from spamming bad blockhashes out of order. Probably would keep other nodes from even accepting it.
you're not rewarded for generating blockhashes (I believe), just from sending valid prepares and commits.
And it is done on chain. There's a work in progress casper contract somewhere around here. Let me see if I can find it
