Wall Observer BTC/USD - Bitcoin price movement tracking & discussion

[kromer]

might as well ask on here: how do you verify (?pgp key) that the bitcoin qt is legit from bitcoin.org ?

http://bitcoin.org/en/download

notice the .exe is 9mb but in actuality it is 11.1 mb.... did someone alter it?

sirus runs that site, i doubt something odd is going on. (unless hacked)

Isn't there a checksum?

Yes, there is a link on the download page "Verify release signatures".

Verifying the checksum of Bitcoin software is important.

If someone were able to change the software on the site, don't you think they'd be able to adjust the checksum mentioned there as well?

That's why developers should always sign the checksums with their keys. However, the client_downloads to checksum_downloads ratio
is daunting.

[Crazy]

I'm so confused.

What is actually driving this movement in China? It must be upper 90% speculation? And why are the moves so tight? Any blip in China and we almost immediately see equivalent movement in US markets. Just bots? Or something else?

Full disclosure: I sold at ~$310 and yes I'm sick about it.

[FTWbitcoinFTW]

or maybe the first wave of interest hit china and all those rich ppl ?

The checksums are signed.

Checksum is for validating bit errors likely to occur in a bit stream i.e. communication channel. It is NOT EVER EVER meant to be used cryptographically!! It is very feasible to modify the file and keep a valid checksum. In fact, CRC was used in the old 802.11/WEP standard as a message authentication code, and we know how well that worked out.

The entire file needs to be signed, or a secure hash (SHA256 hash in this case) that is signed. Signed by whom and validated by whom in which chain of trust is another can of worms best left unopened.

I know that what is actually provided is a SHA256 hash and not a checksum so I'm just being mean :-(

Edit: Technically it should be a MAC like HMAC_SHA256 as a pure SHA256 is vulnerable to a padding based attack, while SHA-3/Keccak in general is not.

I think you are right. I got caught up in lingo, as they name the file SHA256SUMS.asc on their site.

LOL, that made me chuckle.

[jubalix]

when I look at the sell wall there seems nothing to sell after $500 to about $1000+ as if no one is selling??

[solex]

$500 to get murdered next...

Don't worry, I'll be selling on the other side. Others will be too. The price just hasn't gotten high enough to take a position yet.

I think there is a chance the bitcoin representatives may have to walk out on this hearing. Nothing good can come of this if they have already decided bitcoin is directly associated with child porn.
