Zcash is interesting.. But not entirely sure if it's game changing.
FWIW, I share that opinion but about privacy technologies in general, because after deep study of the technologies I am not sure if they work.
Zcash has issues as well, and we have to see how they work out the details. I've lost all hope in Cryptonote/RingCT because of the meta-data issue. I originally thought I would be able to come up with some magic for obscuring the meta-data, but eventually came to realize that the End-to-End Principle (and unrelated but analogously the CAP theorem) always wins and is paramount. I just hope that everyone who has invested their sweat and blood into CN coins, realizes that I don't relish coming to that conclusion. And of course they may have another perspective and think the technology still has value. I think I have already explained my thinking on the matter and so need to repeat myself.
I am just agreeing that I have not concluded that Zcash is the solution either. Devil is in the details (and I don't know about you, but I have other work to do and can't put all of my time into anonymity technology any more, not unless someone is offering me a good opportunity for that line of work and remember cryptography is not my formal area of expertise). I have much better opportunities within my career expertise of producing user facing products for mass adoption.
Enough said that I agree with you. And I am not sure there are any game changing technologies yet. I am not even sure if my attempt to refine Satoshi's design is bullet proof. I won't know until I dig into every detail, dot every 'i', and cross every 't'. I wish CoinHoarder appreciated the work that developers do and how pedantic it is. Broadstroking conclusions without deep understanding of details often leads to incorrect conclusions.
For example, everyone has been so enthusiastic about decentralized file systems (MaidSafe, Storj, Sia, IPFS, etc), but none of us had apparently realized they are not fighting tyranny but rather aiding tyranny as I explained to CoinHoarder upthread. Devil is in the details. DAC sounds so sexy, until one realizes that corporations are inherently not decentralized because otherwise the individuals don't need to share their labor with the parasite corporation if there is no top-down moat around the corporation per Coase's Theory of the Firm. The number of incorrect conceptualizations that Dan Larimer has spawned goes back to the discussions I used to have with him in 2013 on the forum. Actually his intentions are often spot on, e.g. he was focused on electricity consumption back in 2013 and I was not. But as a result he ended up with DPOS and arguing that top-down hierarchies are appropriate for crypto currency. Then he recently admitted they don't work well and has been proposing some basterdized concept of PoS that attempts to mimic PoW (which isn't an entirely accurate summary), which again will be another dead end. So then CoinHoarder gets angry at me for having formed an opinion over the past 3 years of the way those guys think and make choices. And obviously CoinHoarder has formed his opinion of me as well which he has every right to do.
I think the best is to say nothing in forums and share nothing. And then of course make numerous mistakes because no one person is omniscient.
