Topic: ✪ Virtual Coin. an ongoing/repeating scam since 2014? what's going on with the pre-mine?? - page 2. (Read 2914 times)

it certainly seems there's more than a couple of accounts operated by dev/team,

and with much protestation of innocence and good will (still no mention of pre-mine) the new thread is now locked

premine address
http://84.200.210.130:3001/address/VVx2Y6TLchaRAHphTde5ysqv7Y8mLVnuav


now the chain is over 2000 blocks, the premine is available to move ...

I am just amazed by the creativity of the devs who created the hidden premine, and, i am also amazed by Bumbacoin, the way he found this is just, impressive, really a good work.
I aleready saw this coin in the past, it is impressive to see that she is still alive, but Bumba is true, the devs shall explain more about the premine, what is it for, where it is stored.

This is really a strange coin looking quite fishy.
Big premine
No known exchanges or plans for them
Dev locked the old thread and the new one is self moderated
I had two posts asking why there is 2nd relaunch and about roadmaps, but with were deleted by the dev,
It looks like the dev allows only positive comments and funnily they come mostly from newbie accounts 

me thinks the sockpuppets are strong for VC


here's a post from 2014 asking about the pre-mine,

https://bitcointalksearch.org/topic/m.5714562

We all stand behind our DEV & the team. Go shit in your own BumbaCoin.

i dont think coinut read the rules properly

yes, well in fairness old balances will be matched by rewarding tweets.
so a pre-mine maybe implied or at least useful?

the obvious question is whether 387 million coins is strictly necessary to pay for a bunch of tweets at 100 coins each?

Premine was no metioned in the relaunch.

i've setup a temporary explorer.
it's my first attempt with iquidus so no idea how stable it will be where it is

http://84.200.210.130:3001

and the magic block

http://84.200.210.130:3001/block/000000f6bfddb729aa113e3374da77a969bf64778704027ec1faf9d2ec1dc28b

posts are getting deleted.


meanwhile old coin olders are apparently going to get a taste of that 387 million coin premine by perhaps getting a few thousand ..




although on a positive note,
i didnot notice previously, but with 2000 block maturity, means the pre-mine will not be available for quite some time yet.
(not that the dev has bothered mentioning that, nor admitted the pre-mine exists etc …)

github source has been updated,
assumedly to current version.

the reward schedule does not seem to have appreciably changed
pre-mine is evident amongst the confusion of the code.

         if (VcoinHT > 10 && VcoinHT < 12) VcoinRD = pow (pzx,pzy);

with
int pzx = 3;
int pzy = 4*4+2;

block 11 will have a reward of 3^18= 387420489

https://github.com/vcoin-z/virtualcoin/blob/9.2.0/src/main.cpp#L1349



.
the reward for block 11 is not clearly included in source,
the obvious way would be a single line with all relevant info,

if (VcoinHT =11) Vcoinr = 387420489

instead 11 is obfuscated, VcoinHT > 10 && VcoinHT < 1
the whole reward schedule is confusing as fuck.

and the use of pow (pzx,pzy)
(which is a relic of age old Virtual Coin source)
i assume pow is used as it is very similar to PoW and is overtly less suspicious than a direct value,
but pzx and pzy are declared seperately
at https://github.com/vcoin-z/virtualcoin/blob/9.2.0/src/main.cpp#L52  and L57

with the added bonus of pzy also not being a simple clear value, but rather 4*4+2

main thread is unlocked
and getting a lot of attention but no block explorer

https://bitcointalksearch.org/topic/official-virtualcoin-vc-ranked-top-10-v1612today-1756007

okay, so as expected block 12 contains a large amount of coins.(blocks 11 and 13 both show 0 coins)

block 57, 1 coin to VVRUBuL9JGudzoG1zCf7CbepMAmzHqRXkp
block 55, 1 coin to VBbkyGZR6TyWZLxgHPMbrck8oChWSURyJG

seems that the code base generates a new address for each block mined perhaps?


NOTE. to see this information you need a full indexed copy of the blockchain,
to do this you need to restart with
txindex=1
in the conf file.

then to get all info's the following commands are used,
getblockhash
getblock
getrawtransaction
decoderawtransaction

i've decided to keep an eye on VC as it seems an effort in scam pre-mine.
mainly cos of the amusing way they "hid" the pre-mine.

just re-released yet again as version 14.0.2
and they have not updated the github source, i assume because i've been looking at the code and pointing out the premine blocks.

so instead will have to settle for downloading the windows qt and trawling the first 20 or so blocks to see what happens.


EDIT. apparently the win qt is 150 megs, seems excessively large
AND can't unzip it as it's password protected.. havent tried installing yet. need a VM :p

https://drive.google.com/uc?export=download&id=0B0du_MpVWXexbl9KYm9WcWtfb0U

https://bitcointalksearch.org/topic/ann-virtualcoin-vc-signaturetwitter-campaign-bounty-only-few-hours-left-1775186

..
can't unzip,
but the installer generates a ~24 mb qt, and the roaming folder,
i dont have any anti virus installed on teh VM so no idea what else it's doing, but a scan with Trend Micro HouseCall revealed no problems.

for extra lols, here's the new re-jigged Virtual Coin code.
it certainly seems to me that the effort to disguise their pre-mine is highly over done.

https://github.com/vcoin-z/virtualcoin/blob/9.2.0/src/main.cpp#L1326

in particular

         if (VcoinHT > 10 && VcoinHT < 12) VcoinRD = pow (pzx,pzy);
https://github.com/vcoin-z/virtualcoin/blob/9.2.0/src/main.cpp#L1371

with
int pzx = 3;
int pzy = 4*4+2;


possibly
block 11 will have a reward of 3^18= 387420489 ??
confirmed below

they're apparently having connection issues so it's impossible to connect to the network yet to actually look at the block rewards.
but there is a checkpoint for block 13 so i'm guessing it's a big reward

lol yes.
i had to go for a walk around the house to let myself see the obvious :p

Bumbacoin beat me to it. Yes it's 11^6 which is 1,771,561.

    if(nHeight >= 100 && nHeight < 3000) {
        if((nHeight >= 101 && dDiff > 75) || nHeight >= 1000) {
            // 222000/(((x+2600)/9)^2)
            nSubsidy = (222000.0 / (pow((dDiff+2600.0)/9.0,2.0)));
            if (nSubsidy > 25) nSubsidy = 5;
            if (nSubsidy < 5) nSubsidy = 1;
        } else {
            nSubsidy = (1112.0 / (pow((dDiff+51.0)/6.0,2.0)));
            if (nSubsidy > 500) nSubsidy = 5;
            if (nSubsidy < 25) nSubsidy = 1;
        }
    } else {
        nSubsidy = (1111.0 / (pow((dDiff+1.0),2.0)));
        if (nSubsidy > 500) nSubsidy = 5;
        if (nSubsidy < 1) nSubsidy = 1;
           nSubsidy = pow (11.0, 6.0);
   }




haha ok. mystery solved

            nSubsidy = pow (11.0, 6.0);

is 11^6 = 1771561


well that was far more straight forward than i thought . lol

TL/DR

virtual coin has a "hidden" premine of 387420489 coins at block 11
it is hidden by deliberate confusing weird arse use of code, lack of block explorer, silence from Dev, and deletion of posts.

2014 thread with unanswered questions on pre-mine
https://bitcointalksearch.org/topic/m.5714562
=====


I initially looked at VC a few weeks ago and noticed that there was an inordinate amount of coins at the time vs what was obvious in the code.
seemingly their idea to hide the pre-mine was to make the code very confusing.

at the time, VC had re-released (v13.0., seemingly just starting again from scratch (using old gensis etc) with no mention of the previous coin supply.
just wipe the chain and start again from zero.

this thread was initially my curiousity at understanding the code, the text below and next few entries discuss that initial purpose.

now i'm thinking there is a dedicated effort to make VC an ongoing scam coin so i thought i may as well post in this thread about it.

not that i have any problem with pre-mines when handled correctly, but over 387 million coins, seems a tad excessive, especially coupled with no transparency and deleting of posts.

current main official VC thread
https://bitcointalksearch.org/topic/official-virtualcoin-vc-ranked-top-10-v1612today-1756007

and twitter sig campaign thread
https://bitcointalksearch.org/topic/ann-virtualcoin-vc-signaturetwitter-campaign-bounty-only-few-hours-left-1775186

==== timeline as i've seen it.

. Virtual Coin 9.2.0 was released, a simple reboot of the coin, delete the chain and start from 0 again.
. i built a mac qt and received 500(?) for my efforts
. for some reason the dev sent me 100k and it made me wonder what was going on
i noticed there was something like 137 million coins in existence with zero mention of premine, and a confusing code source (see below for actual code)
. after i pointed all this out in thread, the coin was killed
. re-released again, code was changed making the source even more confusing, the premine was modified, but had problems with connection and killed again
. yet more new threads, re-release and dev deleted my post,
this time there is no source released yet, only a windows qt. assumed so no-one will look at the reward schedule.




below is my original post
=====

can anyone explain how these coins were generated by the source?

seems at least a few of the first hundred blocks were 1.77 million coins.
but i canna see how those coins were generated ?*?*?*?*

here's the src,
https://github.com/vcoin-z/virtualcoin/blob/9.2.0/src/main.cpp#L1324 has been updated a little since then
and here's a fork i made just in case
https://github.com/bumbacoin/virtualcoin/blob/9.2.0/src/main.cpp#L1324


here's the blocks for 99 (reward 1771561.00000000) and 101 (reward 1.00000000).

similarly block 100 has a reward of 1771561.00000000 coins. but luckily, the madness stops there and block 101 goes to a 1 coin reward.
