[ANN] [QRK] Quark | POW/POS | 0.10.8.0 - New Self Moderated Thread

[ghzsymc2]

Thanks for recent attention
I'll answer some of the latest questions
I hope I can help as much as possible

-----

In 2017, after years of observing the market
Quark team think pure POW has been unable to meet the demand of development
After the team communicates with the community, the exchange and the mine pool
The vote has decided to upgrade POW+POS+MN

Funded by Max, Crage and Vic, the first phase of upgrade was initiated
They are fantastic contributors
Crage is responsible for the upgrade of the MN
But upgrading from the original chain is far more difficult than copying a piece of code
The test found that our masternode section did not work properly
So in November 2017
We prioritized the release of POW/POS as a transition phase
In the months that followed, third-party development teams stopped providing follow-on development for some reason
（I think the main reason is that the difficulty of development is out of proportion to the reward.This is where the old foundation model feels powerless.）
Then Crage left

After team coordination
I borrowed $20,000 from the owner of the AEX Exchange.（Mr. Huang）
MJ takes over the second phase of masternode development
After nearly ten months of development
The code passed the test.
But did not pass Max's friend's third-party test
MJ thought he was hurt. I think I can understand him to a certain extent.
Then MJ left with the code.
He went to publish QRK2, which you mentioned.（Of course, I don't like him to do that, because that's the code that cost the Foundation $13,000 to complete. It should belong to the Foundation's property.）

Next, at Max's suggestion
I took over the development of the main node.
Because 0.10.6.3 has invalid master node code
So first we need to delete them and release stable versions.（0.10.6.5）
Then add the MN code of DASH.（0.10.7）
Then I met a great developer who had enough skills to help us accomplish the task.And he's very reliable.
The only disadvantage is that his time is not stable enough, often because of some reasons can not be timely development.
I personally lent the foundation new development costs.
The third phase of upgrading officially began
It still takes a long time.
Our simultaneous release of 0.10.6.5 and 0.10.7

You should have heard about the next developments.
We have been strongly attacked.
In 0.10.7.1, we repaired the broken fork.
But there are still two problems to be solved.（These include frequent wallet crashes.）
We have fixed these problems in 0.10.7.2.
At present, the network has restored stability.
But 0.10.7.2 still needs a few days to be officially released, and I hope it will be completed in a week.

I'm sorry for many accidents during the upgrade process.
But I believe that in the future we will have sufficient conditions to ensure that everything works smoothly.

Reward of masternode

Calculate 1% of the total amount each year as a reward for the MN in a year
The reference for ROI is （2019-2020）
Suppose 500 MN， ROI is ≈50%
Suppose 1000 MN， ROI is ≈25%
Suppose 2500 MN ，ROI is ≈10%

Each node requires 10000QRK

The addition of Masternodes also means that Quark will now have a development fund to use for future projects.

It looks that there is no new block anymore since more than 5 hours. Have other the same problem?

Last block was 7156399 at 2019-08-25 00:52:55 (UTC). An again no information from the developers.
What a pity!

[AggroHead]

yes all hashes for block 7156400 are rejected:

Code:

kind of bad miner attack?

At least there are no more wallet crashes. 

[Smartjag]

We would like to invest in more MN, but for that to happen, developers need to communicate more with the community. We try to understand the problems, but the constant occurrence of problems without information from those responsible does not exactly create trust.

[AggroHead]

no more wallet crashes because no new block syncs 

in debug.log you find

Code:

Treasury payment of 106391.232 to QVvYypXoiRXcJpJpRVkftKEjMkXbd6UKJv

same issue as last time...

is it possible to manually correct blocktemplate to mine new correct block?

rpc-getblocktemplate calls CreateNewBlock()
(https://github.com/quark-project/quark/blob/f813e83ee229d9dce9f798051f96ca73f36d91f5/src/rpcmining.cpp#L517)

in CreateNewBlock() after MN-startblock it calls FillBlockPayee()
(https://github.com/quark-project/quark/blob/f813e83ee229d9dce9f798051f96ca73f36d91f5/src/miner.cpp#L360)

where FillTreasuryPayee() is called
(https://github.com/quark-project/quark/blob/f813e83ee229d9dce9f798051f96ca73f36d91f5/src/masternode-payments.cpp#L304)

Two possibilities

Some people are using the new code to generate a lot of rewards for the foundation
(to create panic)

Unknown bugs have emerged as a result of mining along with the old chain during the upgrade

it's a bug - happened during adaption of yiimp-base pool to new coinbase-layout.

getblocktemplate reports wrong scaled values and wallet doesn't check max value for treasury

Yeah! can we get a max value check? Better an error than a 27million coin overrun.
Any Idea where it's getting that magical number? (106,394.92616)

8 hours in seconds is 28800    times the MN reward 3.69416 is very close to the magical number 106391.808 Perhaps some rounding is involved.

I know, it should be a joke

It's nice that we know the mistake now. But it's not nice that the bug occurs repeatedly and nobody from the developers here gives information.

[Smartjag]

Is the reward variable and the difficulty? What's the maximum amount of coisn to mine? Maximum block size?

Why are you asking? According to your posts, you think the blockchain and the corresponding coins are just nonsense of nerds who are not familiar with economy and finance. Do you just want to gamble?

The problem with crypto currencies is not blockchain technology, the problem are the gamblers.

Admittedly, some computer freaks neglect the economic aspect. But wasn't it the same in the dotcom era? Most companies of the dotcom era failed, but those that are left are currently dominating the economy. I have experienced this time and much in blockchain/DLT development is like a Déjà vu for me.

Nerds were not to blame for the financial crisis in 2008, but gamblers who call themselves investment bankers.

For example, we are planning to implement blockchain-based fund raising for non-blockchain SMEs, as we see potential there. There are already successful examples of this in Singapore.

We use master nodes to leverage investments, but we look of course at the underlying projects. In this way we create a win-win situation for all sides.

Therefore QRK is exciting for us and we see a lot of potential, but unfortunately the developers are a bit slowly in fixing problems and communication.

Our developers are currently working on the code and version 10.7.2 will be released shortly

Shortly has elapsed, This idea of trialing code on a once working coin is questionable.
Nothing but wallet crashes on this end.

How many coins are real per day with MN? mno website seems to me giving incorrect information showing Daily income  https://masternodes.online/currencies/QRK/

If the blockchain passes through, the yield is significantly higher. Unfortunately, there are still many faults, especially on weekends.

I understand your concern.  I asked for clarification yesterday and have been told "as soon as possible".
I will update when I get some more details

[Smartjag]

Dear developers,
If you want your community to stand behind you, you need to talk to us. Don't tell us about your history and your problems with gone partners. Tell us when what works and please make sure that all bugs are fixed briefly also at the weekend. "As soon as possible" is not a good answer, especially as we have been put off with "soon" for several weeks now.

You have decided to execute a blockchain and change it to PoS/MN. That's a good thing, but that's a 24/7 job. We currently run many MNs and test 4 MNs from QRK, none of our other MNs causes us as many problems as your MN.

At the last Exchange which offer deposit and withdraw for QRK (FreiExchange), there are less and less buy offers, this is no good sign.
