can this new algo be mined effectively with gpu or it's like the old one that only cpu work and it is not worth to use gpu? i hope the dev understand that runnign a bot fest coin will never do anything good to the project, mining is very centralized now in this coin
The new algo MTP is expected to be kinda like Equihash whereby GPUs can also mine it but it won't be dominated by GPUs only and CPUs can still play a role.
It's still in development though and we're about 70% done.
I have recently got into this coin, the wallet takes 5.25 hrs to load, that's after three days to sync. then i go to mine with it and get run time error's and the wallet crash's. is there any way to make it load faster and actually solo mine? or is there at least a windows miner that i can use for AMD cpu or gpu? i have no clue how to compile and ubuntu will not dual boot with my computer so i am stuck on win 7 x64. I do not get why i have issues with this coin. i have a x6 cpu 8gb ram and rx 480 with a 850w psu. i love mining and i am willing to learn more if i can find the help.
Hey TheFryer, the slow wallet load issue is known and a fix is actually already being tested. From our testing right now it looks very positive. The first load still takes several hours for re-verification but subsequent loads are in minutes. We'll also look at getting a bootstrap up for those who don't want to download the whole chain manually.
For solo mining, may not be that good now and GPU mining is not possible with this algo at this point in time but as this algo is only a stop gap until our new MTP mining algorithm is implemented. Best to try with a pool using this guide which also has links to binaries for Windows:
https://github.com/zcoinofficial/zcoin/wiki/Pool-Mining-Guidepool you use Who version of the wallet , Poramin or Gary?
He is on Poramin's version. The only version that matters right now. But he's still working on some issue with his pool.
Can Founders secretly mint Zerocoins?
No, they (and not including the dev) do not have access to the initial parameters and are subject to the same rules as everyone else.
Did you mean "not
excluding the dev"?..
How do we detect a breach in Zcoin's initial parameters or a vulnerability?In the event of Zcoin's initial parameters being compromised or some other vulnerability is discovered, Zerocoins can be minted. However this is easily detected as total supply is still auditable.
Total supply of coins that should exist = (block number x block reward)
OP_ZEROCOINMINT function shows all mints + 0.1 mint fee
OP_ZEROCOINSPEND shows all spends of Zerocoin
So you know exactly how many Zerocoins have entered the Zerocoin pool and how many Zerocoins have exited the Zerocoin pool.
total supply >= all circular money - (#zerocoin_mint_tx + 0.1 for each tx) + #zerocoin_spend_tx
Remember an example of a bug that can cause things going haywire has been observed in Bitcoin (
https://en.bitcoin.it/wiki/Value_overflow_incident) but it was detected and fixed because the total supply was auditable.
This is not possible with Zcash as transaction amounts are obscured making it impossible to determine so if a flaw is found, this is a much bigger risk. This is the trade off for their added anonymity and we feel it's a risky one although they have attempted to mitigate this by multiple costly security audits.
I have a question here:
ok, lets assume we have detected that something is arong with total supply, so someone is minting "counterfeith" zerocoins... So what next? What can be done to save the coin in such case? Can anything be done, or as soon as it happens, the coin is doomed together with the investment people have made into it?
Yes what I meant was the dev doesn't know the initial parameters either
double negative oops
.
It is noted that knowing the initial parameters does not break the anonymity of transactions, just that it allows the counterfeiting of Zerocoins which isn't really in the RSA accumulator. And as previously mentioned, when the supply doesn't check out, this will be detected.
In such a serious scenario, all Zerocoin spend transactions will probably need to be frozen while we identify the issue (if it's a bug which is the better problem) or whether someone truly knows p and q (which is a worse problem) though we think the latter scenario is highly unlikely. It is in our roadmap to replace these parameters eventually anyway with a non trusted setup which should resolve any remaining concerns but as I understand it, anonymity is preserved in either case.
It's also worth noting that some people have criticized the use of RSA primes. If RSA breaks, a whole lot more things are going to be broken (web browsers, chat applications, email, VPNs, SSL certs) and most likely Zcoin would be the least of your concerns as illustrated in this interesting side read:
