17:17:45op_mul:oh look. ethereum came up with with another bullshit proof of work system.
17:17:49op_mul:https://github.com/ethereum/wiki/wiki/Dagger-Hashimoto
17:18:41op_mul:"Hashimoto aims to simultaneously satisfy two goals.. ASIC-resistance"

17:28:51op_mul:seems to be yet another case of "sergio owned out last stuff, here's one that's 100 times more complex so he doesn't do it again"

17:30:23MRL-Relay:[tacotime] "Hashimoto uses the blockchain as a source of data, simultaneously satisfying (1) and (3) above." Hmm.
17:32:01op_mul:tacotime: recovered from git. "3. **Full chain storage**: mining should require storage of the complete blockchain state (due to the irregular structure of the Ethereum state trie, we anticipate that some pruning will be possible, particularly of some often-used contracts, but we want to minimize this)."

17:34:28op_mul:looks like they had the same problem as Monero in that their proof of work turned out to be a DOS risk due to it being so slow to verify. so you actually end up doing two sets of proof of work just to counteract that.
17:34:44MRL-Relay:[tacotime] Well, if you make the algorithms so complicated that there's a significant barrier to entry in coding optimized versions of them, maybe they're a new class of "optimization resistant" hashing algorithms.
17:37:43op_mul:I'm struggling to comprehend most of the design decisions, let alone trying to think how you could possibly optimise around them.
17:39:42MRL-Relay:[tacotime] op_mul: I just stopped doing that after looking at the source code I guess. You could spend months trying to figure out what everything is doing exactly.
17:41:05MRL-Relay:[tacotime] Unless Ethereum becomes the magic internet currency of the world in 2015, I'm presently satisfied with ignoring it for the time being I guess, because Vitalik constant cranks so many new complex theories and modifies the original design to such an extent that it's really fatiguing to follow.
17:41:20op_mul:which client has this mining code in it? the javascript, cpp, python, go or java implementation?
17:41:58op_mul:ah it has it's own repo in cpp.
17:53:10op_mul:tacotime: yeah. I'm really struggling to parse this one. the sort of useless snippets of the "algorithm" aren't helping (a function that just runs another function and returns the result is not an algorithm). suppose research resistant does work.
17:55:55MRL-Relay:[tacotime] You could always make the hash algorithm "subjective" and run it under trusted computing to make sure it's not using any optimized algorithms to mine that might make allow you to do something they didn't intend. :>
