Three bots for sale:

****************************************************************
*** 1. Star Trek Online Dilithium Producer and Refiner ("Solo bot") for sale: ***
****************************************************************

Hello,

I have unlimited Star Trek Online Dilithium Producer and Refiner ("Solo bot") for sale for 0.5 bitcoins.

The bot needs 1 captain to produce and refine dilithium non-stop.

It uses tricks in the game to circumvent the dilithium caps.

These tricks can also be bought individually for 0.01 bitcoins in case you want to try them out manually.

This bot can be considered a "boot bot". Thanks to the dilithium that it produces it can be used to by more captain slots, by buying zen with dilithium and so forth.

Once more captain slots are available the user can switch to a more efficient bot called the "Switcher Bot".

The switcher bot is 10 times more efficient, easier and of higher quality than this solo bot.

However the solobot has a watchdog which detects if anything goes wrong, the switcher bot has a tiny watchdog as well, however the solobot has been more tested.

The solobot further more has all kinds of features to compensate/recover from situations:

Re-login to server, re-login to account, restart bot, re-cover from update and so forth.

Further details can be discussed via PM or preferably e-mail: skybuck2000@hotmail.com

The bot comes with full python source code so you can inspect it yourself.

Some support is available from me as well, some modifications could be made to suit more of your needs, this additional support comes at the price of 1 bitcoin for a few weeks of support.

Perhaps in the future I will publish some youtube video showing the bot in action, for now consider it a secret.

Here are two screenshot crops of what to expect, keep in mind this was the first bot developed and it's kind of buggy/glitchy (sto itself is glitchy/buggy too) but gets the job done:



Second screenshot crop showing navigation capabilities (just a command in sto, nice, thanks game devs ! Wink)



Bye,

********************************************************************

Hello,

I have unlimited ammounts of Star Trek Online Dilithium Producer and Refiner ("Switcher Bots") for sale.

It comes with full python source code so you can inspect it yourself and be sure there are no strange things in it.

It comes with a manual to explain how to setup it up and run it, some support from me is also available until it's running.

Optionally it has capability of logging back in after a disconnect.

The bot runs flawlessly and is off the most highest quality.

Asking price for this bot is 0.5 bitcoins.

Further details and/or negotiations can be done either via PM on this board or skybuck2000@hotmail.com.

Some secrecy is ofcourse necessary to thwart the game developers.

Usage of the bot is at your own risk I am not resposinble for any reprecussion of the game developers if you reveal yourself.

Either then that the bot seems to be undetected. (It works via a virtual java machine which needs to be installed, which executes a python interpreter, so the bot is just a bunch of text, perhaps this makes it harder to detect).

The bot works by switching your toons, so there will be many logins and logouts, this can be noticed, especially by your friend players, however even this is possible to surpress it with a special trick/software which is available for another 1 bitcoin.

Recommendation is to try this bot out on a newly created toon/captain/account, use the dilithium to buy stuff and then transfer it to other toons.

This way in the event of an account closer little value is lost except the dummy account.

Here is a screenshot crop of the bot to give you an idea what to expect:

This screenshots shows how operations/actions were implemented reliably and how any kind of problem is detected with a timeout, further down (not shown, bot contains code to detect failures and recover from it like server disconnects)



Another screenshot crop to show how the bot finds captains, you will have to replace these graphics with your own captain names, this should be real easy to do thanks to the underlying tool which will be revealed on purchase:



The following screenshot crop shows a part of the bot's main loop code:

*************************************************************
*** 3. Star Trek Online Fleet Alert Bot (to produce fleet marks) for sale: ***
*************************************************************

Hello,

I have unlimited ammounts of Star Trek Online Fleet Alert Bots for sale.

This is the most advanced bot available. It has a full space combat system. It has a navigation system.

It detects capabilities automatic during "boot up" this can be done once if anything changed. It can also store detected capabilities on disk and later load it for fast boot time.

It has scaling options. The faster the CPU the faster the bot will run. If the underlying tool is enhanced by GPU capabilities in the future it may even run faster.

It has "primitive context switching" between all tasks that it needs to do like: Fire weapons, Activate Capabilities like super powers, buffs, etc, Navigate, Detect for abort, Respawn etc.

Therefore it can run on slow PCs and work well, it will work even better on faster PCs, which is quite fun to see.

It has watchdog and re-login features to detect and recover from Star Trek Online Server failures. These can be turned on or off depending on your needs to see errors or to simply run non-stop.

All bots come with a debug log which can be examined for operational details. Like date/time, steps of the bot, and any watchdog detections and so forth.

The python source code of the bot is fully available as well as all of it's graphics for icon detection ofcourse, just like all other bots.

This bot can produce 2000 fleet marks per night (assuming 10 hours). So that's roughly 200 fleet marks per hour.

This bot has been extremely tested (by at least 2 people), cause it was fun and highly profiteable.

The fleet marks can be sold to fleets/starbases/embassies/mines/spires which need fleet marks to build.

This can be done by joining their fleet and requiring payment via the trade window.

Once payment is received the fleet marks can be dumped into their starbase/mine/etc holding projects.

This gives fleet credits which can be turned into EC (a seperate trick available for 0.1 bitcoin) or it can be used to buy ultra very rare special consoles and also fleet ships and other things.

Fleet marks can sell anywhere between 2500 ec up to 12000 ec depending on market supply/demand which is invisible you will need to try/taste this yourself.

Currently the market seems to be flooded with no win scenerio fleet marks which are now easier to come by. Perhaps in the future this will change or not.

At a very minimum you will be able to produce:

2000 * 2500 ec = 5.000.000 ec per night.  (this does not yet include any profits from the fc to ec trick which can basically double this)

Also in the future new profiteable items may be added to the fleet stores.

The best I have seen so far is:

2000 * 12000 ec = 24.000.000 ec per night.

I do have some fleet marks customers in my database (for 0.01 bitcoin I can tell you a customer if you need one). I may also be able to find some more for you if that needed be again for 0.01 bitcoin.

The asking price for this bot will be: 0.25 bitcoin

I offer it to you low, so that you can hopefully make a high profit in Star Trek Online, perhaps some day you can sell some goods and pay for my more expensive bots. (Price is based on usefullness/profiteable of bot not complexity, also rarity)

I have heard that other people use bots as well, I have never seen their source code though. It does make sense, these bots are basically needed to build up starbases which require huge ammounts of dilithium, millions and millions of dilithium.

It's also great to unlock many features like more ship slots, more doff slots, more boff slots, buy zen ships and so forth.

See my other postings for the dilithium bots.

Contact me via PM or preferably: skybuck2000@hotmail.com then perhaps we can work out a deal some support from me will be available as well for an additional (0.025 bitcoin) this will give two weeks of support.

The bot can run federation captains and romulan captains, perhaps klingons too, but this has been less tested, any defects found will be fixed.

Any missing/new powers/buffs can be added as well during the two week support.

Here is a screenshot crop of the fleet alert bot to give you an idea what to expect (ignore the federation title in it, it can support klingons by now too):

225  Economy / Digital goods / Star Trek Online Voth Bulwark Dreadnought Cruiser for sale. on: December 21, 2013, 09:06:03 AM
Hello,

I have 1 Voth Bulwark Dreadnought Cruiser available for sale for 0.5 bitcoin. This ship is brand new and was released on 20 december 2013, it's now part of the voth ship set (bastion, palisade, bulward).

This is probably the biggest ship available to federation players at this moment. It's selling for 350.000.000 energy credits on the exchange right now, it will probably dip down and then after 6 jan 2014 rise up as it's supply runs out. It is unknown when this ship will be made available to players again, perhaps it's a one time emission perhaps not, only time will tell.

It has some unique capabilities:

As far as I know it's the only ship available to the federation which comes with a battle cloak. This means the ship can cloak while in combat.

It also comes equiped with a 180 arc torpedo. (Combining this with the quantum wide angle torpedo would allow this ship to fire two torpedoes while flanking ! That's unheard of in star trek ?!)

It also has some kind of repair pet/ship.

Some more information about it can be found here, and seen here:

The promotion pack where it came out of, I was lucky enough to get one:

Apperently Satoshi used something like 50, 18 down to 15 computers, some computers probably broke because of overheat.

Where does a person get 18 computers ?

If it was the guy from Mircrosoft then maybe he installed some invisible bitcoin client on Microsoft's computers.

The electricity bill would have gone up during his period of mining in 2009.

This could be on record on electrical bills.
228  Bitcoin / Bitcoin Technical Support / Re: I think I got robbed for 0.0005 bitcoins and why it may matter for the future. on: December 01, 2013, 11:29:31 AM
Doesn't make sense, you have a remaining balance, why would you get robbed for a low amount when there's more in that address?

You sure it wasn't a change address?

As far as I remember I did not want to pay any transaction fees, there is an option in the bitcoin client that says: "transaction fee: 0".

Apperently that's some optional transaction fee ? I don't understand how that would be collected or why it would matter ? I guess it has something to do with many many destinations or so or perhaps comments for the transaction... really weird.

So I believed I could do free small transactions and then somehow bitcoin send 0.001 btc ? then 0.0005 was taken away as transaction costs, and 0.0005 was returned or so ? or just 0.00000001 ?

You guys suppose to figure out what happened not me Smiley

So what does it look like to you ?
229  Bitcoin / Bitcoin Technical Support / Re: I think I got robbed for 0.0005 bitcoins and why it may matter for the future. on: December 01, 2013, 11:25:47 AM
It also always prompts and asks in the GUI if it needs to provide a fee to satisify the network rules, and in current software the fee required to satisfy the rules for dust transactions is 0.0001BTC/kb, so 0.0005 sounds surprising unless the transaction was build from a lot of dust or done with an old version of the software.

I have two older versions of the software still on my harddisk, one of them was used:

bitcoin-0.4.0-win32
bitcoin-0.5.0rc7-win32

Today I installed a new version:

bitcoin-0.8.5-win32

I just started up one of the older versions: 0.4.0-beta. It's actually better for displaying the ammounts, it shows all 8 decimal places behind the comma.

I think what happened is the following:

Perhaps I got confused by the text in options, maybe I didn't read or understand it right it says:

"Optional transaction fee per kB etc". The new client still says this.

Perhaps I believed the 0 in that field indicates that no transaction costs will be charged, so for a newby maybe this mislead me believing that it was free.

How can a newb have any idea what this field is about Huh I still find it a bit weird to this day Wink

Also why 0 transaction fees (still) not allowed ? weird.

I also find it a bit weird that no miner is present... if people want to play the lottery why stop them ?

231  Bitcoin / Bitcoin Technical Support / I think I got robbed for 0.0005 bitcoins and why it may matter for the future. on: December 01, 2013, 10:25:03 AM
Hello,

I think the robbery went down as follows:

1. I was testing bitcoin at the time to see if it can handle the minimum ammount which was something like 0.00000001.

2. I set the transaction fee to 0. (At least I think so ? Can I go back in time in the blockchain and see if a transaction fee was offered or not by me ?)

3. I send the minimum ammount to myself, to a new bitcoin address.

4. The transaction was accepted and confirmed and is now part of the blockchain however: 0.0005 bitcoins were deducted from the account where I sent it from, so that transaction now says: -0.0005    

(also the client doesn't even show the 0.00000001 maybe it gets rounded or so in the gui, also the client crashes was trying to catch up to latest blocks I will restart that later on).

So apperently somebody accepted the transaction but still charged transaction fees ? Is this allowed ?

The issue at hand is:

If in the future people want to make small little bitcoin transactions and they set the transaction fee to 0 they might be fooled into believing it's free, while in reality they get "robbed" like this ?! Wink Smiley

So either I did something wrong ? Or bitcoin robbed me ! =D

(Another possibility could be that the little transaction was getting through for free and maybe I set the transaction fee to 0.0005 ? I don't think I would do that but I simply can't remember so... there ya go 3 possibilities.)

232  Bitcoin / Bitcoin Discussion / Re: Bitcoin will probably be dead within 6 years. on: December 01, 2013, 06:23:17 AM
Bitcoin userbase is growing 10 fold per year (hence the blockchain is growing 10 fold)

3 million users estimate now
30 million 1 year
300 million 2 years
3 billion 3 years
30 billion 4 years

Before 6 years there will not be enough people left in the world to become bitcoin users
Moore's law will outpace bitcoin once there are no more people left to use bitcoin.

Good point, however, people may start to use bitcoin more and more and more, still leading to some additional doubling of volumes Smiley which could still be somewhat problematic. Perhaps even 10 folds.

Perhaps games will start to use bitcoin. I wouldn't recommend it because it would make bitcoin explode almost literally, but we are all powerless to stop it.
If such a scenerio happens we could be seeing a 100x fold, 1000x fold or even 1000000 fold pretty much overnight. That'll be the end of it quite quickly.
Huge ammounts of transactions happen in some games. It would probably dwarf bitcoin easily.

In the real world, maybe transactions don't happen that much, at least the usual stuff, like groceries, buying a pizza, filling the car tank gas, then again there are also the financial world and such... which could have high volumes... imagine all of that switching to bitcoin ? SmileySmileySmiley

Yes there are all sorts of extra factors - but there is a tipping point somewhere were either Moore's law takes over and the blockchain (relatively speaking) gets smaller and smaller, or the computing resources available to run bitcoin become too expensive and bitcoin fails. (Changing the hash algorithm is apperently possible, but are there any quantum safe hashing algorithms ? however all bitcoin accounts/addresses may be cracked and perhaps history changed).

Ultimately though the blockchain cannot continue to grow exponentially - at which point price performance of computing makes it easier and easier to run bitcoin (blockchain etc)

Perhaps quantum harddisks will come to exist, perhaps they can store much more information Wink

Perhaps quantum computers can keep running bitcoin, or perhaps they will crack bitcoin and then it spectacularly fails Smiley (apperently hash algorithm can be changed but are there any quantum safe hashing algorithms ? rsa/bitcoin accounts/addresses would be cracked/plundered ? or perhaps does that curve algorithm protect against quantum attacks ? Wink blockchain could probably be faked/recomputed though could be detected Wink)

Another good point you make, even with a distributed database, it cannot continue to grow exponentially, unless maybe quantum computers can handle exponential growth ? Wink

When bitcoin runs out of harddisk space it will probaby stop functioning and it will simply crash/fail like you say.

However some people may still have some harddisk space so then perhaps it will continue to function for those lucky few Wink

I think in reality big corporations like google, microsoft, facebook might take over and store the blockchain on their harddisks which they have plenty of.

Thus bitcoin might turn into a client/server system which pretty much make it the biggest fail ever Smiley it will happily continue running, but it's original idea is d.e.a.d Smiley

LOL, but then the funny part is... even google/microsoft/facebook will have the exponential growth and eventually will have to give up ? Smiley
233  Bitcoin / Bitcoin Discussion / Re: Bitcoin will probably be dead within 6 years. on: December 01, 2013, 06:12:02 AM
It "utilizes" a server, in a sense, to provide small parts of the blockchain. However, it doesn't have to trust the server, due to SPV verification.

Ok this is very funny, this could explain some double spents/attacks. Satoshi admitted this mode isn't too safe:

""the verification is reliable as long as honest nodes control the network".

"
This is a concern in a situation where an SPV client is subjected to a double-spend attack by somebody who controls its network connection. For example, suppose you are at a wi-fi cafe and are paying for something using your smartphone -- the cafe owner controls your network connection.
"

^ Perhaps cafe owner can quickly double spent any change ?! Wink

Why do newcomers need to download the blockchain? Its a public ledger available online, its not necessary for 99.9% of the bitcoin community to ever download locally.

Bitcoin is supposed to be a p2p system, using the web or any other central point for download or transaction-only-interaction pretty much defeats the original idea, not that that will stop anybody from using it apperently.

However do you trust the web ? Seems dangerous and a security risk Wink

SPV, used in Electrum/MultiBit, can verify transactions, without the whole block chain, or central reliance.

I don't think this is correct, somebody will still need to store the entire blockchain. The website for electrum mentions a "server". From the looks of it this client is communicating with their server to get the blocks. And you trust that ? Wink Smiley

237  Bitcoin / Bitcoin Discussion / Re: Why did Satoshi Nakamoto create bitcoin? on: December 01, 2013, 05:22:31 AM
Just curious, why did he create bitcoin?

A pyramid scheme is my best bet.

1. He "invents" it Wink
2. He mines it for 50 bitcoins each time.
3. He makes sure others can only get 25 bitcoins and less and less, making his 50 bitcoins worth more eventually/on the long run.
4. He limits the output to 21 million ensuring his bitcoins become worth even more.
5. Perhaps even writes a sloppy client so even more wallets are lost lol Wink
6. Uses multiple cpus from the start to out smart single cpu users Wink
7. Announces/publishes it after he mined lots of t.
8. Perhaps even got into contact with criminals/drug dealers to make the system popular and get a user base Wink
9. He designs the system to give out some free bitcoins/money to encourage others to spread the word, like a true pyramid system, making them coins more valuable.
10. All bitcoin users behave like pyramid scheme suckers, promoting it to others to make them coins more valuable and sought after/desired.

Now he has some problems perhaps:

1. Perhaps he lost the private keys, seems somewhat unlikey, but a harddisk crash or other corruptions because of overheat is plausible.
2. He cant spent the coins, those coins will be watched like hawks on rabbits, if he does he may be arrested for questioning Wink
3. Database is getting out of control, he may run out of time to cash in.
4. Other attacks/problems possible too, virus/trojans/etc.

Others/the system have problems too:
1. Perhaps some private keys lost to crashes.
2. Millions of bitcoins stolen.
3. Millions of bitcoins to be seized.
And then people claim the chinese are coming... no I think the loss of bitcoins is what triggered the shot up in dollar value.
Perhaps the price was being controlled by silk road and such... now that he's gone the price free-falls upwards because of bitcoin shortage.
And yes... the chinese may be coming as well adding insult to injury Smiley

It was a brilliant scheme to get rich quick... and many suckers fell for it ! =D

Other motivates might be at play as well (for example assuming it was Samsung, Toshiba, Motorola):
1. Selling lots of cpu/gpus/hardware.
2. Overheating/kill PCs trying to bring back demand for PCs Wink
238  Bitcoin / Bitcoin Discussion / Re: Depressed that I was not an early adopter on: December 01, 2013, 05:16:49 AM
Can't help but feel this way

No need to feel depressed.

When it was announced on slashdot for example the difficulty started to go up.

One had a few days to mine some coins is my guess.

After that the gpus took over.

You escaped from overheat/pc death, that's worth something too ! Wink
239  Bitcoin / Bitcoin Discussion / Bitcoin will probably be dead within 6 years. on: December 01, 2013, 05:14:09 AM
Currently the database seems to 10 fold each 1.5 years or so.

11 GB today.
100 GB 1.5 years from now
1 TB 3 years from now
10 TB 4.5 years from now.
100 TB 6 years from now.
1 PB 7.5 years from now.
10 PB 9 years from now.
100 PB 10.5 years from now.

Nobody can predict the future, though there are some trends.

Harddisk size will probably not keep up with the database size.
Raid systems will also fall short a few years later.

This also does not include additional popularity/transaction volume for bitcoin, if transaction volume goes up further and thus database size goes up faster it might even end much sooner, maybe even within 5 or 4 or 3 years.

One possible solution that could safe bitcoin is a distributed database size, where computers only store a part of the blockchain and will have to rely on each other to provide some sort of trust/security.

However this may also lead to additional network bandwidth requirements for checking/traversing inputs to see if they are spendable.

Downloading the blockchain itself is already somewhat of a problem for newcomers and people that were dorment for a while, it takes quite a long time, this could hamper it's popularity/up take. A distributed database my solve this problem somewhat as well.

I think development of bitcoin should focus on and give priority too distributing the database in some form or another if bitcoin is too survive, otherwise it's going to be a lot of fun watching it literally crash and burn ! Wink =D Like that episode of southpark: "poooof and it's gone ! =D"

Perhaps alt-coins will take over for a while, until they too run into similiar problems, and then the other alt-alt-coins will take over and so forth Smiley
Though perhaps users of bitcoin then in a jam... can't really go along with it unless new harddisks bought.

Prices of harddisks may start to rise a bit in the coming years.
Raid systems might become popular among bitcoin users.
And perhaps other storage solutions, perhaps network attached storage devices with additional capacity.

Also I wonder a little bit what happens if somebody wants to send some bitcoins to some address, will the checking/traversing time for input checking increase as well ? For example the inputs to be used where from long ago ? Does bitcoin perhaps find the nearest input ? How that work ? Maybe some smart indexing or keeping track of inputs ? Perhaps that not a problem...

Another little concern now that I am venting some concerns is with the difficulty only being raised each 2016 blocks. Apperently this is somewhat strange... somewhat like people getting free rides. They purchase enough computation power to ride out that 2016 block range with ease... and take all the pie ? hmmm bit strange, I guess it remains fair to all, except that the 10 minutes is further reduced to something much faster ? So estimates when last bitcoin may be mined could be off, to way off.

Seeing that difficulty raise to huge proportions is kinda funny, it shows the inability of humans to work together efficiently and take only what they need/deserve. If all would mine with 1 cpu the difficulty would have remained much lower and all would have gotten their fair share Wink
The difficulty is a reflection of greed among the miners. They want all bitcoins to be theirs however it will never really be theirs, the difficulty will always adjust to 10 minutes or so, however if they have most processing power then they might still get all of it if they a bit lucky Wink
It could also reflect that there is some profit being made, which would allow reinvestments into hardware, or it could be investment gambles which may fail.

Oh yeah and finally there is one other little thing I wonder about, bitcoin assumes sha256 will always have hashes with zeros in front. I wonder if perhaps this is not true and some day the system will get stuck at a certain difficulty because sha256 can no longer produce hashes with enough zeros in front of it.
Personally I think this may be somewhat unlikely but I dont know the algorithm that well, has anybody analyzed if such a situation is possible ?

No the opposite ofcourse, if he can find one, he can find two, or three or four, hence my suggestion to add as many hashes as possible.

So my suggestion is:

Check point hash 0 = Hash(block 0, block 1, block 2, block 3, etc up to block 2015)
Check point hash 1 = Hash(block 2016, block 2017, block 2018, etc up to block 2016+2016-1)
Check point hash 2 = Hash(block 2016 * Hash Number to (Block 2016 * (Hash Number+1))-1)
Check point hash 3 = etc

^ This will lead to many more hashes and best part is that all block hashes are included, not just a few, actually the entire block should be hashed, why stop at only block hashes ? Wink Yes it would lead to more computational effort but that's basically the point in general, however perhaps block hashes only would be enough, it's already difficulty enough to fake one, however including all could give a bit more security because it adds dates, times, transactions, etc, but maybe could also lead to less security because of easy adjusting comments or other bogus information, with a hash only that would be a bit more difficult to do it could throw off all input calcultions to try and fake such a hash.Blocks can probably fluctuate in size, while for now the hash is always same size, so gives some constant speed and also easy to implement reliably without all kinds of potential strange block size quircks).



The blockchain is already a chain of hashes.  The hash for block 2 uses the hash of block 1 as (part of) its input and the hash for block 3 uses the hash for block 2 and so on.

If you were to change a single bit for block 10, then the hashes for all blocks from 10 onwards would change.  Ofc, that would mean that blocks 11 onwards would no longer meet the proof of work (which is the whole point).  You can't change anything without destroying the chain entirely.

The SHA-256 function breaks large messages into pieces for processing anyway.  It uses the output from one piece as the input into the next piece.

There are two possibilities where this would not happen:

1. Either change enough bits in such a way that the hash stays the same. This is called a "hash collision".

2. Or perhaps insert a block which has the same hash, again a hash collission except it's doubled:  block 1.5 to be inserted has same hash as block 1, block 2 will happily accept block 1.5.
