I'd love to see a site that nicely shows (probably on one long page) the 1yr chart vs bitcoin of all sufficiently-aged alt-coins. I'd guess 99%+ would look like LTC and MSC.

Bitcoin is the first monetary system to credibly offer perfect information to all economic participants.
But Bitcointalk & /r/bitcoin are heavily censored. bitco.in/forum, forum.bitcoin.com, and /r/btc are open.

Mastercoin flushed.
Speaking of those guys, they are getting desperate now.

They are changing the name of the project in an attempt to escape their past bad press.

Several developers have quit in disgust.

D.J. and JR. W. are sending out emails trying to recruit more projects like Maidsafe they can use to pull more MSC bagholders.

I don't think it will do them much good in the end.

no.  just let them die.  the sooner that happens, the sooner Bitcoin can Moon.

Litecoin isn't holding back Bitcoin from mooning. The premise there is wrong in my opinion. Bitcoin will succeed whether or not Litecoin does.

People will speculate despite what some may want. I should know I was and still am one of them.  Cheesy

<chart showing obliteration of litecoin price>

The scale is a bit misleading. It looks perhaps like LTC is down 99% but look at the numbers. It is down from about 0.03 to 0.01.

Bitcoin is down a similar amount against USD. 

(Granted LTC is priced against BTC so down ~90% against USD).

what is "constant time"?

Improved signing security

For 0.10 the security of signing against unusual attacks has been improved by making the signatures constant time and deterministic.

This change is a result of switching signing to use libsecp256k1 instead of OpenSSL. Libsecp256k1 is a cryptographic library optimized for the curve Bitcoin uses which was created by Bitcoin Core developer Pieter Wuille.

There exist attacks[1] against most ECC implementations where an attacker on shared virtual machine hardware could extract a private key if they could cause a target to sign using the same key hundreds of times. While using shared hosts and reusing keys are inadvisable for other reasons, it's a better practice to avoid the exposure.

OpenSSL has code in their source repository for derandomization and reduction in timing leaks, and we've eagerly wanted to use it for a long time but this functionality has still not made its way into a released version of OpenSSL. Libsecp256k1 achieves significantly stronger protection: As far as we're aware this is the only deployed implementation of constant time signing for the curve Bitcoin uses and we have reason to believe that libsecp256k1 is better tested and more thoroughly reviewed than the implementation in OpenSSL.

[1] https://eprint.iacr.org/2014/161.pdf


A countermeasure against

http://en.m.wikipedia.org/wiki/Timing_attack

?

Although I can't think of a practical scenario where a typical user would ever be exposed to this, yes, the concern is side-channel attacks (e.g., a timing attack):

( ... cut a lot of helpful links, quote and explanations ... )

I think deterministic signatures are much more important than constant-time signatures (there's been a non-trivial amount of funds lost due to the repeat k-value problem but I doubt a single satoshi has ever been lost due to a genuine side-channel attack).  Someone like gmaxwell could comment better on the practical risks here…

I concur with all you said. I think that Pieter Wuille took a chance to snap in this "constant time" thing while writing libsecp256k1. What seems weird to me is that they don't mention the main advantage of replacing OpenSSL with such "custom made" signing tool: speed.

Quoting a gmaxwell's email to the bitocoin-development mailing list (related to the headers-first sync feature):

Quote from: gmaxwell
(I'm using 295k as the target here because after that point ecdsa
dominates, and then your 6+x faster libsecp256k makes more of a
difference)
(bold is mine)



Bitcoin is a participatory system which ought to respect the right of self determinism of all of its users - Gregory Maxwell.

(Granted LTC is priced against BTC so down ~90% against USD).


Nov 29 2013, LTC was at 0.043BTC, which was about $47. LTC = $2.74 today, so that's a fall of 94.2% against the dollar (and a fall of 80% against bitcoin at current 0.00859BTC/LTC).

Yes and from the peak of 1163, BTC is now down 73%. At its recently low of 275, it was down 76%. Not quite as bad as LTC but nothing to cheer about either.

Although Syriza's lead in the opinion polls has been narrowing in recent weeks, there is concern in the markets and among EU officials that a new Greek government could throw out many of the fiscal reforms implemented by Mr Samaras's coalition with the left-of-centre Pasok party.

the left-wing Syriza party leading the polls wants the terms of a huge EU-IMF bailout renegotiated. That could cause some upsets in the financial markets, and may even lead to a greek exit of the euro??
