Ahhh... Bitcoin memes and green candles. Reminds me of the good old days on the original Wall Observer when pages went by faster than you could shitpost more memes.

College is a huge scam.  People are going into debt for thousands of dollars for a useless piece of paper.  You can already learn everything for free with all the resources out there.  It's quite funny, the wealthiest people I know didn't even attend college.

This may be off topic but the majority of wealth being created is going straight to the top.  We are more productive than ever but wages have been stagnant.  Younger generations can barely even afford to live with the rising housing and medical costs.  Capitalism is going to implode on itself. 

Maybe it is a scam for some occupations, but I wouldn't want my doctor to have "learned it on the internetz". Sure, that's not what you ment but...

I would like to hear peopleís stories about how they first heard about Bitcoin ?

I read about it in Wired Magazine in early 2013.  I was familiar with gold farming in WOW so it didnít seem too outlandish.  It took a second mention in the media in November 2013 for me to pay attention and find this forum on google.

I stumpled on bitcoin back in the autumn of 2012 through a random google search: At the time I was thinking of investing my surplus student loan (a few hundred usd worth) and thought about possible industries that I should invest in. I had this notion that the internet revolution wasn't over yet but rather one industry at a time was still being revolutionzed from the less conservative to more conservative. I tried to think of industries that were ultra conservative and hadn't really been digitized yet. Banking was the obvious answer (actually thought of car industry first) and after some random googling I stumpled on Bitcoin through pure luck.

Bought Bitcoin with everything I had to spare at 9usd IIRC. Couldn't believe my luck when Bitcoin started mooning soon thereafter and, of course, sold most like a fool. I hadn't really thought through my investment strategy in the case if I actually was right. You could say I took a big investment risk but hadn't properly planned on how to take profit out of it which was idiotic. In the end, I still have about 25% my original Bitcoin. And, no, I'm not rich as I only had very little money to invest back then. But I did pay back my student loan with profits which was nice.

OH MY GOD!! : DDD That Twitter feed is pure gold. I'm convinced that too few funny posts/memes in this thread led to this bear market in the first place, but the fundamentals have seen much improvement recently what with the hats and videos like that.

Whatever happened to Risto, BTW?

He was institutionalized due to bipolar before, IIRC. Now he's out of country so nobody's looking after him and he has by all likelihood relapsed into psychotic mania.

The ultra-individualism/liberalism is strong in this thread!

Historically speaking it's almost funny how individualistic we are in the west these days. So much so that I don't think it's going to last.

Just sayin'..

From reddit:

He paid for the membership, I'm not sure he can be removed without a refund.
So the Bitcoin Foundation has suspended the withdrawal of board members?

Naah, they probably just have their funds stored at Gox and are now being goxxed themselves. What a clusterfuck....  Undecided

Why aren't businesses adopting bitcoin payments like crazy? we really should start with this now. Amazon, get on with it. We have to make this sustainable and not reliable on the fragile human psychology.



Because its still actually shit as a simple currency. Check reddit story of guy who buys a burito and has to wait an hour for confirmations, ends up paying them fiat aswell just to get home.

Uh, 0-confirm transactions are just fine for small purchases. Vendors need to get on with the program.
Yeah, this is ridiculous.

There's actually a pretty simple way around this even for bigger transactions: A hardware wallet with an internal balance counter. The hardware wallet would prevent double/overspending and only incoming transactions confirmed by a trusted third party would be added to the internal balance counter. Whenever you'd pay with this hardware wallet the hw would sync the balance with the third party, if possible, and then sign the transaction and asymmetrically sign the transaction with a manufacturer provided private key (inorder to assure the receiver of the payment that this is indeed an authentic hw wallet made by the said manufacturer). This way the receiver of that transaction can check if both signatures are valid and, if so, he/she can be instantly certain that he will receive the coins. This would make offline transactions possible, too.

Of course this means that the private keys can only exist on that hw wallet. (Actually you could have another backup hw wallet which, if used, would revoke the manufacturer certified second signature. This could also be used to spend your coins in case the trusted third party should stop providing the confirmed incoming transaction data.)

All this would be possible without ever having to trust your coins to any third party online service... Basically like your average CC/debit card but better. I actually suggested this to Trezor but they seemed to have issues with understanding the concept.
9  Bitcoin / Development & Technical Discussion / A hobbyist programmer's take on the selfish miner issue on: November 20, 2013, 10:23:42 PM
Just a quick and rough idea that I just came up with. Might be that this has been suggested before and/or that this idea is downright stupid but I thought that not sharing this would be even more stupid if there's even a slight chance that there's something to this.

The idea is really quite simple; a node should prefer within a 2 block window (and perhaps some arbitrary time window, say 30 seconds) that part of the block chain that contains most transactions per block. However, only those new transactions that the node was aware of BEFORE receiving the new competing branches of block chain would be counted towards the transactions-per-block count. (This way the selfish miners couldn't increase their transactions-per-block count using non-publicized self-to-self transactions.)

This way if a selfish miner tries to keep a block (or multiple blocks) that was/were found earlier secret it is more likely that this branch will contain less transactions per block than a block that was found later on by honest miners. After a conflict situation it'd now be more likely that the majority of the network would continue mining on the honest miners' branch and the selfish miners' branch would be discarded.

This would also have a unintended side-effect of potentially filling blocks in the block chain more efficiently due to the fact that bigger blocks would be preferred to smaller blocks published within the time window and miners/pools would be incentivized to contain more transactions in a block (by updating their work more often).

Any and all feedback is appreciated!

So I go to the newsvendor and get the paper, but then I can't get a coffee next door, because I'm on cooldown?



Sure you can if the payee supports sending the transaction to the balance management database. The database will respond with a confirmation (digitally signed) which will then revoke the cool off time. The cool off time is there only to make sure that the database is up to date even if the payee doesn't support sending the signed transaction to the database for confirmation...

What if my newsvendor is out in his shitty little kiosk in the street? Cause newsvendors usually are.

Think of this as an equivalent for a debit/credit card; you'll need internet access for instant confirmation. :/ But the HW wallet could be connected to the internet, for example, through your phone using Bluetooth.

It could also just be GSM (I think is the acronym for what phones use?) enabled. This would allow usage pretty much anywhere.

That's a valid possibility.. Usage offline is possible too (like with the TREZOR), of course, but then it's just like any other bitcoin transaction; the payee's not safe until the transaction is in the block chain.

EDIT: .. And like I wrote above the cool off time was actually a flawed idea and unnecessary. But you can still make the transaction without connection to the database, however, but the payee cannot be sure of receiving the payment until he/she has the bitcoins just like with offline credit card payments.

Instead of cooloff time, it can show a warning to user or it should confirm from user whenever he tries to send money.

Yes, actually now that I come to think of it there's no real need for the cool off time: whenever the key is about to make a database synchronized transaction it can also confirm any older transaction with the database before signing a new transaction.....

Thanks....
