1  Other / Off-topic / Chair Fatigue on: October 07, 2014, 10:11:48 PM
I was wondering, what other people who sit in a chair all day and work at the computer do to cope with chair fatigue. i mean the aching back and rear end. for me i try to exercise a bit everyday when i wake up and again before bed, but i still end up hurting every day around 5 pm. What do you do to cope with "chair fatigue"?
2  Other / Meta / I demand that cooldgamer be forced to remove fraudulent negative trust on: October 07, 2014, 04:07:26 PM
cooldgamer has left a negative trust on my profile, quite fraudulently. I asked a question about getting some a positive trust on my profile. i attempted to setup a trade in which a stipulation was that the user should be a hero member, i would send first, and we should exchange feedback. What is the crime in that?

It would appear that, because some scammers have used this technique(trust system manipulation), i am not allowed to gain trust in this community, even by offering myself as the sacrificial lamb by sending first. That is not fair. These guys with the positive trust have a monopoly on the trust system so that only them and their friends can be in the positive trust. I want to establish myself in the positive trust, but apparently i am not allowed to do so without being accused of being a scammer, when i have not done anything wrong.

I don't see the crime in stating that i would like to establish positive trust. Logically, a scammer would not be so in the open about it. He would sneak around, making small trades until he was in the positive trust, and then he would use it to pull off a big scam. By being so open about it, the topic will always exist where i sought for the positive trust, so wouldn't that throw a wrench in any attempt to scam by me anyway?

I want to sell coding services at some point on this forum, this is why i seek the positive trust, so that maybe clients will be more inclined to give my proposal more consideration.

But my point, if i have one, is that cooldgamer has left me a negative trust without due diligence. I want an explanation, and i also want to reach some type of an agreement where it can be removed from my profile. I have no intention to scam. Zero. Zilch. Nada. None whatsoever. I simply want the positive trust for my coding services. Reputation is everything on the web, and i want to establish a good one. why the hard time?

3  Other / Meta / cooldgamer abuse of the trust system on: October 07, 2014, 03:00:00 PM;u=79720

he left me a negative trust for no reason. it is not a crime to stipulate that a user must leave a positive feedback after a successful trade. i request you leave him a negative feedback for abusing the trust system. I have posted here on and off since july of last year, and it is not fair that he would just leave me a negative feedback. I have done nothing wrong, why should my account wear the badge of dishonor because of this?
4  Economy / Currency exchange / [New terms][WTB] $10 btc with paypal. i send first on: October 07, 2014, 12:38:07 PM
Original Post so the forums paranoid vocal minority can't claim i tried to cover this up
Hero member or other reputable member only. must have positive trust. After the chargeback window is closed on paypal, or whenever you are ready, you are to send me the btc. I am accepting the risk that you will not send the btc as recorded in your agreement. if you break the agreement or if i break the agreement, negative trust will be left for the breaker of the agreement. after transaction is complete and both users are sure that the deal was successful, positive feedback is to be exchanged with this thread as reference.

This has been updated because according to some people with some pull on this forum feels like this constitutes untrustworthy behavior. I don't feel like this is particularly true, but i do see their side of the argument, since it has been a proven sign of scammers to seek a positive trust, albeit they do it more covertly for the most part.

i do still want to buy into bitcoin using paypal if anyone is interested. I will buy $10 USD worth of bitcoin instead of my original offer of $5.

 I still only want to do it with trusted members or atleast someone who is well known and has positive feedback for similar trades, but i am nixing the requirement to exchange trust. I will probably leave you a feedback. you can if you want, it doesn't matter. please do not pm me directly. that is an automatic red flag to me. please post in this thread only.
5  Other / Meta / How can i get a green trust on my profile? on: October 07, 2014, 12:26:40 PM
I was thinking of finding reputable hero members and asking them to do trades with me. i would send first, proving i am trustworthy. Really i just want it for bragging rights. My friends at work will be jealous of my green trust rating

Edit:The negative trust is not there because i scammed someone. please read them carefully. A couple of overzealous forum security guards are blackballing me. why i'm not sure, but i really don't care. i certainly haven't done anything wrong at all. They are just queers.

8  Bitcoin / Bitcoin Discussion / F.R.O.N.T. Attack Vector and What the Bitcoin Devs are doing to prevent it. on: October 06, 2014, 01:48:34 AM
I would like to share with you a vulnerability in the Bitcoin protocol I've been thinking of which might have impact on the future of Bitcoin. Please criticize it!
The Freeze on Transaction Problem

The freeze problem occurs if someone publishes a transaction with fees much higher than the block subsidy. I don’t remember who described the attack first. Suppose that, by mistake, a transaction is published with 50 BTC in fees. The transaction is included in a block at height n. If everyone acts rationally in his own interest, then the best choice for the remaining miners is to try to mine a competing block at the same height n including the high-fee transaction, to collect the fee for themselves. All the miners having solved the block at height n, now move on mining at height (n+1). But they won’t choose each other branches until one branch is sufficiently longer so that it is better to switch to it and abandon their own branch rather than try to keep the block with the high fee. This case is different from the real block competition case we see periodically on the blockchain, where the miners are generally split between two branches. Here there are multiple branches competing. If there are 10 “top” miners each having 10% of the network hashing power, then 10 different branches will compete. The analysis for this case is similar to the Gambler’s Ruin problem analysis present in the Satoshi paper, but with a fixed constant monetary incentive not to switch. Since the incentive to switch grows exponentially with the branch length difference, any initial constant is diluted. In the special and rare case that all the miners have exactly the same hashing power, then the network diverges, and this is equivalent as having two miners having exactly 50% of the hashing power each. So in principle the freeze on transaction problem is just a temporary disruption in the network, but not a fatal halt. Nevertheless, since during the freeze period each miner is mining on his own branch, it also means that moving forward with blocks is a lot slower. Assuming 10 miners having 10% of the total hashing power each (+/- 3%), the network becomes 10 times slower. I simulated it with a 50 BTC tx freeze fee, and 10 miners, and it takes approximately 6 blocks to converge, so the freeze time is approximately 60 times the block interval, or 10 hours. If the distribution is approximately 25% of the hashing power for each top miner, the freeze time is 4 hours.

Obviously what’s needed for the freeze problem to occur is that miners are 100% rational, greedy and prepared. They need to have a modified version of bitcoind which can automatically detect a high-fee transaction and prevent adding to the best chain a not-owned block containing such transaction. There will be no time for the miners to patch bitcoind if such transaction is manually spotted. Also the latest versions of bitcoind have preventions not to allow high fees by mistake. So the freeze problem is currently non-existent, but may pop up in the future in form of a state-sponsored attack.

The Freeze problem as an Attack

If an attacker plans to repeat such attack periodically at the expense of wasting a lot of BTC, there is little the current protocol can do, because miners will be prepared to take advantage of the attack. If the attacker issues a new fee burning transaction before the network converges, then the attacker can maintain incentives to keep every miner separated in his own branch. So wasting 50 BTC every 4 hours, an attacker can maintain the network frozen forever.  Even if we restrict the maximum fee per transaction, the scripting system has infinite ways to create transactions whose output can be taken by anyone, and the attacker can announce the method miners can use to collect those BTC and even prepare and publish the bitcoind patches to automate collecting those transaction outputs.

The best thing the community can do is act together and cooperate to share the high transaction fee. This will neutralize the attack completely and allow miners to earn extra bitcoins. But cooperation in the Bitcoin community has never been easy. There is a technical solution which is to modify the Bitcoin protocol so that every transaction output has a maturity time of 6 blocks, and if a transaction output is redeemed multiple times in a 6 block interval, then the BTC amount is split between all redeemers, and also fees would be automatically shared in a 6 block sliding window. At a first glance, this provides a way for miners to cooperate even anonymously and there is no immediate drawback, but an in depth analysis is necessary.

If i understand this correctly, this would take an deleberate, orchestrated and very costly attack in order to exploit the vulnerability. Personally, it does not weaken my belief in bitcoin at all; Many of crypto's greatest minds have already drafted proposed fixes for this theoretical vulnerability. Unfortunately, the best solution will make transactions in the bitcoin network even slower.

What say ye?
9  Alternate cryptocurrencies / Altcoin Discussion / My favorite Cryptocoins on: December 14, 2013, 01:22:06 PM

The Original, you can't go wrong with bitcoin. Such a cool innovation i couldn't create  a list like this without giving it a mention. You rock bitcoin!


Litecoin uses the scrypt algorithm, the first of its kind. It deserves a mention here as well.


A coin before its time, PPcoin is a modern innovation that allows us to explore beyond the end of proof of work mining. An awesome coin that deserves recognition.


The first coin to take the PoS algorithm introduced by PPcoin and apply it to a scrypt algorithm, Novacoin has since went on to solve many bugs in the original PPcoin source, such as the floating point math in Stake calculation which was flawed.


A totally new proof of work, offering pseudo scientific value by computing cunningham chains or prime chains. Another great innovation in the cryptoworld. This one has been slowly fading, however it could blow at any moment.

Honorable Mentions
Introduction of the Kimoto Gravity Well algorithm keeps this borderline scrypt coin squarely atop the Honorable Mentions list. This coin would have more interest if it wasn't for its shameless reward of early miners with the majority of coins in circulation. Other than this small gripe, this coin is a winner with a large community and overall proffessional team.

This rising star in the crypto community is able to store files in the blockchain at a price of 50 Datacoins per megabyte. Look for Datacoin to make a bigger splash in the coming months as the crypto world slowly opens their minds to this exciting new technology. Best case scenario the moon, worst case scenario Namecoin, which isn't exactly bad company. Sign me up.

Out of all the coins i have mined, this one has been the hardest next to bitcoin. After digging, it appears to be a clone of something called Bounty coin, and also there are mentions of PPcoin and "minerscoin" in the source code. On oct 18th, this coin was at 50 gh/s and was hit with an attack of 3.3 th/s, yet yielded only 1449 blocks during the 24 hour period, which is a testament to the strength of ppcoin, which this coin is ultimately derived from. After googling this coin, i'm surprised how much info is out there about it. One gripe i have is that it was premined(this is not fud, it even says so in the source code). I would like to see something done with this coin along the lines of what Devcoin is supposed to be, being that it should atleast attempt to align its self with the greater opensource community as a whole. Could be a good marketing strategy and could help the coin carve out a useful niche.

Memorycoin--No website
This coin was once a very promising coin, with a grant system where coin holders could vote for grants to be awarded. Think of it as a Devcoin with a Parliament/Congress/Committee controlling the projects the coin could be used to support. I've been hearing rumblings that this coin could be relaunching soon with a few tweaks. If it does, this is one to definitely keep an eye on.

well, thats my list! thanks for reading. if you enjoyed my delusional ramblins, BTCeam me up scotty! 18LXhfxgbJpaW343uTALmrayvVGg9MkRmZ

Did i miss a coin thats notable? let me know! i will consider your suggestions.  Cool

hi everyone my name is h4xx0r. before you freak out, i am a white hat, so don't worry about me hacking into your stuff, because i won't do that. I have been working hard over the past few months to create a new coin that atleast adds some fun to the proof of work algorithm, and offers proof of stake as a security measure and prolonged mining incentive. I won't release much info about the coin yet, but i just wanted to let you know who i am, what i'm about and why i'm here. I look forward to learning and growing with the fine community here. TGIF and God Bless my new friends.
