Does anyone else feel like we shouldn’t change the zcash algorithm?
If the community splinters into a GPU driven fork of the coin to just run away from ASICs that will always catch up, should we just not all band together to continue building zcash strength and awareness.
I really like this project for the community that it comes with. Something about Zookos vision, and the equihash algorithm, the 0 knowledge proofs, and other aspects of zcash that make it so strong.
If a increased hash rate continues to drive this project forward, that’s a good thing for all of us. I’ve seen other projects fork and it weakens the community and support for the coin.
So instead of bitching about ASIC’s vs GPU’s
Lets just all get together and do this! Let’s get it
Changing Equihash parameters from (200,9) to (144,5) would actually be returning to the intended parameters at launch.
Prior to launch, the built-in CPU solver was not optimized, so there was a fear that solutions with (144,5) would take too long to find, given the block interval of 2.5 mins. Also, we didn’t know how much of a speedup GPU miners offered.
Changing the PoW parameters can also have benefits such as improving verification time, which would help Ethereum Solidity contracts to verify Zcash blocks, as well as tphones and constrained devices such as Raspberry Pi’s.
If someone discovered a security bug in the PoW, we would also have to change it.
bitcartel, your thoughts on the equihash algo are very insightful. However, I wonder how long it will take bitmain to modify their ASIC’s to run at 144,5 instead of 200,9?
ultimately, the asic resistant aspects of zcash and the equihash algo was one of the main reasons many of us decided to mine ZEC imo.
I guess what I’m saying this that we can run away from the ASIC’s (which we all knew were coming eventually) or we can face this thing head on.
If the Z9 which produces 10K Sol/s was not MADE FOR US the zcash mining community, then I do not know who it’s intended for. Fighting this thing is like taking on a cannon with a bow and arrow. It wont work in the long run, unless we use the cannons ourselves…
So why don’t we all amp up our hash rates, and start moving ZEC into a top 10 market cap position where it belongs. We’re still < $1B market cap as of this writing.
After all, we are talking about specialized hardware that was built to help us run this algo.
Why mess with a good thing, when we can do the complete opposite and embrace it.
I maybe wrong, but I rather see these things in the hands of the community than some corporate mining farm that will destroy our interests entirely.
for me the situation is as following, I`m a private guy and I don’t want to get rich, but I want to make some money, for power and others. I want to use a ASIC miner to host it effectivly outside my home.
If zChash is changing their algo, my invest is lost and I will stop mining.
this doesn’t change anything. A company and/or successfull project should make their decisions for the projects favour, not about the wishes/profits of a handfull miners, no matter if gpu, asic, fpga, cpu or whatever.
At this point I think a move from PoW to PoS is the best scenario for everyone. Doing this would level the playing field substantially so that GPU miners can still be a relevant and part of the community. PoS would increase the amount of memory required for the ASIC to the point that external memory chips would need to be used. This would lower the performance of ASIC architecture, but would by no means render them useless or prevent future ASIC development. In addition, there are several security concerns pertaining to the use of PoW as recently pointed out by Ethereum’s founder Vitalik Buterin. He said the following:
“PoW is extremely expensive, and furthermore is fundamentally vulnerable to 51% spawn camping attacks with no effective strategy for recovering from one. Selfish mining is profitable starting at 25-33% hashpower, and 51% censorship attacks are definitely profitable.”
Is this alone not a reason to consider a move from PoW to PoS? When we add in the issue of centralization and exponential increase of network hash rate and difficulty due to ASICS, I think there’s more than enough ammunition to make this argument. At this point, I’m not sure why the ZCash team is hesitating, unless there’s some unknown security or technical reason. Having more folks in the ZCash community has many benefits and also helps facilitate the ultimate goal of ZEC being adopted as an actual currency that’s used daily.
Two of you guys are already mining with a Z9 Mini, so how does it benefit you to change the algo parameters from 200,9 to 144,5? It will dummy your Z9 investments and do what, fracture a part of the Zcash community. I just don’t see the benefit guys, help me understand.
