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.temporary blockexplorer with premine adress
http://84.200.210.130:3001/address/VVx2Y6TLchaRAHphTde5ysqv7Y8mLVnuav2014 thread with unanswered questions on pre-mine
https://bitcointalk.org/index.php?topic=516183.msg5714562#msg5714562=====
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 threadhttps://bitcointalk.org/index.php?topic=1756007.0and twitter sig campaign thread
https://bitcointalk.org/index.php?topic=1775186.0==== 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 int64 nSubsidy = 50;
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);
}
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.
