Had my hash divided between a few pools when suprnova was doing better, now it seems some of the miners with a majority of hash power decided to move. I am moving everything back to suprnova to prevent one pool from dominating. Unfortunately some of those top miners have the equivalent of $50,000+ worth of hashing power, so if we can get even one of the top miners back over to suprnova things would balance out.
I also pointed back all my workers to SuprNova : hope the unluck will change to luck ;-).

Well I switched to suprnova again with my 1.4Mhs/s, i mined for 24h in miningpoolhub and i get the same coins so... i wont help this centralization as i get the same coins
Really ?
In the last days ?
Can you explain how it is possible ?

Because I also switched beetween SuprNova and MiningPoolHub in the last 2 days and I earned 5 times more with poolmininghub than with suprnova !

And the explaination is here :
SuprNova : block 30671 -> (un)luck 504.85, more than 2 days to mine  (less than half a block in 24 hours).
PoolMiningHub : in 24 h, more than 70 blocks found, luck 98 %., earned 5 time more than SuprNova.

Theorically, in a very long period (in a infinite period), earning should be equal, but in reality, since 15 days, SuprNova is completely out : a very too big (unluck : look at the stats on the site).

I took note of how much i was mining on suprnova days before, then i switched to miningpoolhub and i was getting the same maybe a bit more so...

Indeed i get 4-5 times more shares in suprnova compared to miningpoolhub
You are a very very very lucky guy.
Is that possible to be so lucky ?

Say me what block on Suprnova and poolmininghub and the luck numbers.
Lasts block and luck on SuprNova :
 30,280 (april 17) -> luck 73.28
 30,390 -> luck 202,50
 30,405 -> luck 17 (good luck but not enough to make a normal average with the others blocks)
 30,671 -> luck 504.85
 30,712 -> luck 64,76
In the lasts 4 days the unluck of SuprNova was 172,48 : you earned about 2 times less than espected and on MiningPoolHub (average luck on the lasts 7 days with 555 blocks found : 96,64%).

Yes, you are very lucky to earn the same amount with SuprNova than MiningPoolHub in the last 4 days : the only possibility is to began mining just a little time before block 30,405 and stop mining just after :-).

In my words, there is no reproach made to SuprNova/OCMiner :-).
The problem is the concentration of the mining at more than 50% on the same pool : poolmininghub.

With new coins, some pools temporarily dominating the hashrate is common. Had a brief chat in our #mining channel in Slack to find out what's going on. There was a mass exodus from Suprnova for some reason when they were previously the number one pool.

However now Suprnova is having a 0% fee promotion time so I highly recommend our miners to switch some of their hashrate over to achieve a more fairer distribution. If you have any problems @ocminer is always ready to help.

pool.mn https://pool.mn/xzc/ and maxminers https://xzc.maxminers.net/ also have working pools as far as I know.

Anyway problem should be better once MTP is up.
We progress in the discussion : now you admits that the mining is centralized to more than 50% on a single pool.

You minimize the scope of the risk because, unfortunately, as a developer, you can do nothing, otherwise call the miners to leave poolmininghub for going on SuprNova or another pool, what you do and I thank you .

The problem is that the miners on SuprNova have not received anything since 2 days while they would have received the income of 160 blocks at the same time on poolmininghub.
Miners pay for their electricity and their equipment: I doubt that there are many who follow this call to sacrifice themselves.

XZC can be attacked at any time by the team of poolmininghub and, even more serious, a hacker may be tempted to attack poolmininghub to make an attack on XZC.

Our XZCs are absolutely not safe !

I think the good advice to those who own XZC is to sell them until this problem is solved (by the new algo or something else).

I would like other holders (non-speculators) to give their opinion here.

Im also into zcoin, but i would like to see a response from the dev about the big centralization of the power of mining

Hi, what is your concern on miner centralization and where are you getting evidence that it is centralized?

Currently both GPUs and CPUs can mine it and no ASICS have been developed so anyone can mine.

There are a couple of big pools Suprnova, Miningpoolhub, Pool.mn and some in China so I think we're quite healthy. We do plan to develop p2pool for it soon but need to get some other stuff fixed first but in this case I think it's just a lot of people who are comfortable with Suprnova rather than an actual problem.
Hi,

Getting some evidence that XZC mining is centralized ?
Very simple !

For exemple :
At the moment : the network hashrate is 17,19 GHs and miningpoolhub hashrate is 10,8 GHs (62,83 % !). SuNova hashrate is only 0,4 GHs, no blocks found since 46 hours.
XZC is PoW and PoW currencies are attackable with 51% attack : here we are at more than 62 % !
XZC is now attackable.

An other exemple of evidence :
Look at this page : https://zcoin.miningpoolhub.com/index.php?page=statistics&action=blocks.
In the last 24 hours, 79/144 blocks were found by the same pool : 54,86 % !
In the last week, 573/1008 blocks were found by this unique pool : 56,84 % !

XZC is not any more secure.
At any time miningpoolhub can recalculate old blocks in the blockhain and insert fraudulent transactions there. These transactions can steal the coins of any XZC holder.
XZC is now without security, without protection and can be attacked at any time.


@Dev : what can ou do to retrieve XZC security ?
I am a XZC miner and I hold my coins since the begining : I want my XZC in security in the blockchain, not robbed in 1, 2 or more days...

Sorry guys but this coin is pretty centralized, it's hard to keep up with so low hash on the pool, hopefully it'll get better after the algo switch.
The big mining centralisation of ZCoin is a big issue for his security, no (51% attack) ?
How the community can manage this ?
How the dev can do something ?

If the security of the coin (his blockchain, then the mining) is not guaranty, ZCoin value is zero.
Very sorry to tell this :-(.

Looks like you're the weird guy who adviced to buy RISE, the money recently retired from Bittrex Smiley Smiley Smiley

https://bitcointalk.org/index.php?topic=1460658.0
I was the french translator of RISE [ANN].

How does it change the serious ZCoin security problem?

I am not weired and I'm not a newbie like you.

Where is the problem with ZCoin ?
More specificly, where is the ZCoin mining money ?

I am a ZCoin miner since many months.

The current network hashrate is 20,000 MHs
A pool like SuprNova is 500 MHs (40 time less than all the network).
The reward is 40 XZC for one block each 10 mn.
For one week, the reward is 40 XZC per ten mn x 6 time 10 mn per hour x 24 hours per day x 7 days per wek = 40,320 XZc per week.

SuprNova should win 40,320 XZC per week for all the network / 40 time less than all the network (hashrate) = 1008 XZc per week or 25,2 blocks a week (1008 XZc / 40 XZC per bloc).
Then last week, SuprNova earned only 16 blocs with an (un)luck of 113,18 : the unluck would be 25,2 I 16 = 157,5 (https://xzc.suprnova.cc/index.php?page=statistics&action=blocks).
A unluck of more 150 for all a week is quasi impossible !!!
And it is the same thing for the week before : allways less reward than expected, even for a long time.

I had a look to others pools (pool.mn and maximiner) : It's the same or worse.

WHERE GOES THE XZC MINING REWARD ?

I wish good luck to all sellers of Zcoin!
Thank you.
I wish good luck to all buyers of ZCoin ;-).

I believe I have found the root cause of the problems with m7m and SHA. The sph final function
re-initializes the context while the openssl version does not. The code sph in m7m took advantage of
this silent init while openssl was left with stale data.

I have also found that sha256t works at suprnova, but not at yiimp. This looks like a pool issue.

All issues with SHA should be fixed in the next release.
Congratulation : good work :-).

(price is a joke : impossible to know a price before more developments, but... 32,000 Minerum * 0.1 btc = 3,200 btc = 3,500,000 $ : not bad)

4000 ETH address had been post.god .can't believe!

no need to be surprised ..i think all the people posts more than one ETH address
How can you do that (IP verification) ?

can someone tell me how to install this version? since unlike other cpuminer this version dont have any install instruction (for linux)

thank you for anyone who try to help me Smiley
