You should get some of those BTC

You could use whatever you want as a password/key, and have your own private hash function that key maps to 256 bits.

For starters, your key is, 123456, and your hash is to simply sha-2 it once.

That wouldn't be very secure, but you can add complexity as you please.

Your key could also be "use sha-2 eleven times on this string to produce my secret private key", and then your key and your private hash function are the same

1 shirt please

someone write a script that enters fake user data on the scam site

Did you finish high school? How dare you release such a paper? Wow.

I think it's cause BTC is getting real life traction, but no alt does.

Pizze deliverey, Zynga, Netflix, Ebay, Colorado Kush, etc, all allow spending BTC, but no notable alt service yet

To answer the question, Bitcoin can change any part about it's protocol, if enough people accept that change.

To comment on cracking SHA-2, I suspect most people talking about this don't even understand what cracking a hash function means. If this were to happen however, there is a solid chance that all hashes at once get broken, and no Quark or Litecoin offers a solution.

Really enjoyed this write up from Vitalik

I can't comment on the matter at hand but just for perspective:
They have an office in Berlin, I was there recently. It's not some website-only company, and you can see their names on the site, which makes this a bit unlikely to be a scam.

I want coins which are as few tx deep as possible. That never changes, they stay fresh until moved.

I guess I just contact someone who is mining.

[LBC] is already reserved

I needed to pay for a Hotel in foreign currency and they would only accept credit cards. Ridic fees on both ends. Sad. We will see if BTC will be better.

Is there a way to get my hands on coins which are freshly mined?

I want coins which have only been around for a short amount of time, a max of 4 tx deep to reach the newly created output from a block.

How do I get my hands on those?


On the flip side, if I wanted to get old, very worn coins, from on the first blocks with endlessly deep spending trees, how can I get those?

Thanks

You should attach a leaflet with information / links to resources to increase the chance of adoption.

Also make sure you explain what you are handing out at the time of handing it out. Without trying to insult anyone, many waiters and pizza deliverers are not tech-savvy or spend-an-hour-to-find-out-about-something type people, they are likely to see it as advertisement and trash it, or to just put it on their stack of other papers and forget about it.

There is certainly some truth to that joke. BTC are mostly useful for moving large amounts of money around the globe quickly and cheaply.

Buying a $3 latte is already not too cheap with an 8cent tx fee, 2.66%, more than the often quoted average 2.5% paypal or visa fee.

addresses that don't check? could be true. Does someone know?

lol what is going on there

3BTC in lost funds, tons of micro transactions, some gigantic transactions with fees only...

There is different safety mechanism next to first place anonymity.

No one can force you to return your bitcoins. You don't need to store bitcoins in your matress to hide them. You just store them in the cloud with a password, or just as a private key on a piece of paper, whichever you prefer.

Now theoretically your coins could get flagged and even though they can't be taken away from you, you wouldn't be able to use them. But this would mean the majority of the network agrees on some centralized flagging mechanism. But that very idea goes directly against the ideology of most nodes in the network and is thus very unlikely to happen.

First drugs, then porn, then the rest of the economy, muahahaha

I'm not clicking a link on this forum, especially not from someone's first post. Sorry.
