Zokko is a paid by Ver/Wu shill. He deleted Peter Todd's Asic resistance code. Peter Todd is a famous Bitcoin Core developer, and as we know Ver is in open war with them. We all know that the money in zcahs team came exclusively by Ver, so no doubt what is going on.

fucking scam bent on censoring dissent... betrayal from day one, from the setup, to the secret miners, to know censorship... shame on the devs, team and supporters. fools and fooled.
Hey everyone, I recently did this video (https://www.youtube.com/watch?v=oPdnG03eI58) showing some of the recent Deception and Misdirection that the ZCash team has pushed on us all over the last 1.5 years and ofcoarse more recently over the last week with the announcement of the Z9.

Zcash Company has invested in StarkWare Industries, a new company developing STARKs.
STARKs are a new cryptographic proof system which is scalable, toxic-waste-free, and post-quantum secure.
STARKs may prove to be useful for building more secure and scalable blockchains, as well as potentially providing privacy and computational integrity to other applications beyond blockchains.

Hi;
Does the current team have a plan for "Antminer Z9 mini"? Like continuous hard fork in Monero?
Kind regards

What happened to zcash? the price still the same as what the price last week.
I was thinking about selling my mined coins because I feel that the price of zcash will fall sooner.
We need hardfork! Fuck bitmain!
What happens to bitmain?
Looks like I'm late to the news about zcash, bitcoin is continuous increasing, but the price of zcash still the same price as what happened last a few days ago.

ASIC in itself is not the problem. In-fact a GPU is also an ASIC. What is the problem is that a few manufacturers will dominate the market with equipment that is dedicated. Where general purpose consumer miners provided a very diverse group that support the consensus mechanism. Some use Linux, other windows or even Android and Mac. Some use Nivida, AMD and in the near future Intel and there is a verity of equihash software out now. Of which some are even opensource. It is highly unlikely with such a diverse group that there will be an easy exploit that can threaten the network. Unlike ASIC miners that in all likelihood has a backdoor programmed in or a few bugs. If there is some exploit then GPU miners can easily update their software where ASIC miners can't.
forget about the small-time miners. They are screwed regardless of ASIC or not. It's about the diversity of the coins consensus mechanism. Think about a disease hitting a homogeneous population that has little resistance to that disease. That population will become extinct if the disease is lethal. But if the population has diversity then some will be affected but others will be resistant. if Zooko /Zcash does not see the threat then they should suffer the consequences

I was wondering why there's no ZCASH ANN Thread here so I decided to launch one, the following info is copy + paste from http://z.cash:

WHAT IS ZCASH?
Zcash offers total payment confidentiality, while still maintaining a decentralized network using a public blockchain. Unlike Bitcoin, Zcash transactions automatically hide the sender, recipient, and value of all transactions on the blockchain. Only those with the correct view key can see the contents. Users have complete control and can opt-in to provide others with their view key at their discretion.
Zcash transactions do not depend on the cooperation of other parties.
Since the contents of Zcash transactions are encrypted and private, the system uses a novel cryptographic method to verify payments.
Zcash uses a zero-knowledge proof construction called a zk-SNARK, developed by our team of experienced cryptographers. These constructions allow the network to maintain a secure ledger of balances without disclosing the parties or amounts involved. Instead of publicly demonstrating spend-authority and transaction values, the transaction metadata is encrypted and zk-SNARKs are used to prove that nobody is cheating or stealing.
All of the authors of the Zerocash protocol are on our team, which includes most of the creators of the Zerocoin protocol and leading researchers of zk-SNARKs themselves.
Zcash is a decentralized and open-source cryptocurrency that offers privacy and selective transparency of transactions. Zcash payments are published on a public blockchain, but the sender, recipient, and amount of a transaction remain private.
Zcash is based on peer-reviewed cryptographic research, and built by a security-specialized engineering team on an open source platform based on Bitcoin Core's battle-tested codebase. Our improvement over Bitcoin is the addition of privacy. Zcash uses advanced cryptographic techniques, namely zero-knowledge proofs, to guarantee the validity of transactions without revealing additional information about them.
Our zero-knowledge proving scheme makes it possible to conceal values and other identifying information from the public blockchain. Users simply prove that the values balance out and that they are not double-spending the amount they want to send.
Download the Tech Preview release here, or get started with our Beta Guide. For more in-depth technical specification, see our developer wiki's specification page.
The Zcash company aims to set a new standard for privacy through the use of groundbreaking cryptography.
In an open and programmable financial system, privacy is the only way to ensure fungibility and guarantee that cryptocurrency can be interchangeable as a fluid medium of exchange for users. Companies need the protection of privacy along their supply chain in order to conduct their business, especially in the context of public blockchains. In addition, we believe that personal privacy is necessary for core human values like dignity, intimacy, and morality.
We are a science-driven team. Our scientists and engineers are the discoverers of the underlying scientific principles and the designers of the protocol; we are not the controllers or the power-holders, and do not control the mining or distribution of Zcash. Every user of Zcash contributes to its decentralization, helping to protect it against failure and corruption. Our team is one among many participants in the network. We created Zcash, but its ultimate destiny lies not in our hands, but in yours.

My Information so far:
2.5 minute block times, 12.5 ZEC per block
(so the same 50 ZEC per 10 minutes as Bitcoin)
- During the first four years, 80% goes to miners and 20% to Founders' Reward (so miners get 10 ZEC per block for first four years, then 6.25 ZEC, and then halving after)
- During the first ~month, the block reward ramps up linearly from 0.005(ish?) ZEC to 12.5 ZEC
(the mining slow start)
Suprnova's Pool:
https://zec.suprnova.cc
Official, public standalone Miner:
https://github.com/str4d/zcash/tree/standalone-miner
I don't think there's a windows version yet, but it runs fine on linux.
Be aware that this is a a very slow "test-only" cpu miner, so once a public GPU miner will be available, hashing will be much faster.
There is no ICO.
The coin has not launched yet, it will or should launch around 28.th of October, there's testnet currently where miners, pools, transactions etc. are tested.
Mining is done with a new algo called "Equihash" - it's not compatible with any ASIC, it's currently mineable by CPU and GPU - there are no public miners yet.
However there is a big open source miner contest here: http://zcashminers.org/ - you can earn up to $30k if you publish your miner.
The Algo is very slow, about 0.7-1 soltutions (hashes) per second. (Yes, you read that right). I'll be mining it for sure
The technology looks interesting and promising, there seems to be a big dev team behind it, it's good to see things are finally getting real.
Twitter is full with messages about zcash, so it seems to catch attention pretty well, astonished me even more that there's no ANN here.
I've played around with it a lot and hope to have a full functioning pool up at launch, chances that everything works out and I'll be ready are looking pretty good right now, stay tuned and get yourself informed about the coin.
I'll update this post once I get more information about miners, pools the exact launch dates, issues and so on...
Feel free to discuss and post your findings

Hopefully all Equihash coins will stand up against Bitmains aggression's....
Lets try to be the leader in this and get out in front of Bitmains release and make them worthless.....

In my opinion, this is the most promising project on the anonymity of payments. The development team has very competently approached this issue. The fact that people like Edward Snowden use this coin speaks volumes!
